Description

Display panel and display device

Technical Field

The present invention relates to the field of display technologies, and in particular, to a display panel and a display device.

Background

With the rapid development of internet technology and display technology, intelligent mobile terminal devices in people's daily life play an increasingly important role. The intelligent mobile terminal equipment can acquire the latest information at any time and any place, realize real-time interaction with other intelligent equipment and meet various requirements in life and work. Meanwhile, people also put forward higher requirements on the display effect of the intelligent mobile terminal with the display screen, and the display screens such as 'frameless' and 'full screen' become research hotspots in the display field. The larger screen occupation ratio brings more excellent visual experience to users, and can display more information, so that the pursuit of the larger screen occupation ratio becomes the mainstream development trend of display products.

In order to realize the full-screen display, a camera needs to be directly placed below the liquid crystal display panel, because the density of the sub-Pixels in the image pick-up area is less than that of the sub-Pixels in the normal display area, the sub-pixel arrangement mode of the image pick-up area is difficult to realize the display of high pixel density (Pixels Per inc, PPI), and in order to ensure that the brightness of the image pick-up area is consistent with that of the normal display area, the brightness reduction problem caused by the reduction of the pixel density can be compensated by improving the brightness of a single sub-pixel in the area, so that the brightness uniformity of the whole display area is realized. However, after the brightness of the sub-pixels in the image pickup area is increased, bright lines exist at the boundary between the image pickup area and the normal display area during display, so that the split screen affects the display effect.

Disclosure of Invention

In view of this, the present invention provides a display panel and a display device, in which a virtual pixel unit is disposed at a boundary between a first display area and a second display area, so as to effectively avoid a problem of bright lines at the boundary.

In one aspect, the present invention provides a display panel, which includes a display area, the display area includes a first display area and a second display area, the first display area includes a first pixel unit, the second display area includes a second pixel unit, and a light transmittance of the first display area is greater than a light transmittance of the second display area;

the first pixel unit adjacent to the second display area is a first transition pixel unit, and the second pixel unit adjacent to the first display area is a second transition pixel unit;

the first transition pixel unit includes a plurality of first sub-pixels and auxiliary sub-pixels, the first sub-pixels and the auxiliary sub-pixels are different in color, the auxiliary sub-pixels include at least two auxiliary sub-sections, and the area of the auxiliary sub-sections is smaller than that of the first sub-pixels, and the second transition pixel unit includes a plurality of second sub-pixels;

the display region further includes a dummy pixel unit including sub-pixels of a plurality of different emission colors, and the dummy pixel unit includes the auxiliary sub-section, the second sub-pixels adjacent to the auxiliary sub-section and having different colors.

In another aspect, the present invention provides a display device including any one of the display panels provided in the present application.

Compared with the prior art, the display panel and the display device provided by the invention at least realize the following beneficial effects:

the display panel and the display device provided by the invention comprise display areas, wherein each display area comprises a first display area and a second display area, the light transmittance of the first display area is greater than that of the second display area, and in order to realize the brightness uniformity of the first display area and the second display area, the brightness of sub-pixels in the first display area is set to be higher than that of sub-pixels in the second display area, but bright lines can appear at the junction of the first display area and the second display area. Therefore, the first transition pixel unit comprises a plurality of first sub-pixels and auxiliary sub-pixels, the colors of the first sub-pixels and the auxiliary sub-pixels are different, the auxiliary sub-pixels comprise at least two auxiliary sub-portions, the area of the auxiliary sub-portions is smaller than that of the first sub-pixels, and the second transition pixel unit comprises a plurality of second sub-pixels; the display area further comprises a virtual pixel unit, the virtual pixel unit comprises sub-pixels with different light-emitting colors, and the virtual pixel unit comprises an auxiliary sub-portion and a second sub-pixel which is adjacent to the auxiliary sub-portion and has different colors. Because the auxiliary sub-pixel comprises at least two auxiliary sub-portions, the area of the auxiliary sub-portions is smaller than that of the first sub-pixel, the brightness of the auxiliary sub-portions only partially assists the brightness of the sub-pixels, and the light-emitting brightness of the auxiliary sub-portions is smaller than that of the first sub-pixel, the brightness of the auxiliary sub-portions can be compensated to superpose the brightness of the first pixel unit and the brightness of the second pixel unit during display, so that the light-emitting brightness of the auxiliary sub-portions in the same virtual pixel unit is similar to that of the second sub-pixel and also similar to that of the first sub-pixel, when a picture is displayed, the brightness of the virtual pixel unit is similar to that of other pixel units, the problem that bright lines can appear at the junction of the first display area and the second display area is avoided, and the display uniformity of the display panel is improved.

Of course, it is not necessary for any product in which the present invention is practiced to achieve all of the above-described technical effects simultaneously.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

Fig. 1 is a schematic structural diagram of a display panel in the prior art, and fig. 2 is a partial enlarged view of Q in fig. 1. In adisplay panel 100 provided by the prior art, thedisplay panel 100 includes a display area AA, where the display area AA includes a first display area AA1 and a second display area AA 2; the first display area AA1 includes afirst pixel unit 01, thefirst pixel unit 01 includes a plurality offirst sub-pixels 011, the second display area AA2 includes a plurality ofsecond pixel units 02, thesecond pixel units 02 include a plurality ofsecond sub-pixels 021, and the light transmittance of the first display area AA1 is greater than that of the second display area AA 2; it is further required to set the density of thefirst pixel cells 01 in the first display area AA1 to be greater than the density of thesecond pixel cells 02 in the second display area AA 2. The first display area AA1 may be used for placing optical devices such as an image pickup device, but the present invention is not limited thereto. In practical applications, the display panel can be roughly divided into a conventional Pixel technology and a Pixel Rendering (SPR) technology according to the Pixel arrangement and the driving manner of the display panel. Specifically, the first display area AA1 may adopt the conventional pixel technology, that is, in the display stage, the pixels are clearly divided and independent from each other, and the adjacent pixel units do not need to share the sub-pixels. In order to improve the resolution, SPR may be adopted in the second display area AA2, that is, in the display stage, thesecond pixel units 02 are not arranged independently, and the adjacentsecond pixel units 02 need to share at least onesecond sub-pixel 021, so that thesecond pixel unit 02 adjacent to the first display area AA1 needs to borrow thefirst sub-pixel 011a in the first display area AA1, that is, the luminance of thefirst sub-pixel 011a includes both the luminance of thefirst pixel unit 01 in the display process and the luminance of thesecond pixel unit 02 in the display process, which results in that the luminance of thefirst sub-pixel 011a borrowed by thesecond pixel unit 02 is greater than the luminance of the otherfirst sub-pixels 011b and greater than the luminance of thesecond sub-pixel 021. Meanwhile, in order to keep the brightness of the first display area AA1 and the second display area AA2 in thedisplay panel 100 consistent, the brightness of thefirst pixel unit 01 in the first display area AA1 is increased to compensate the problem of brightness reduction caused by the density reduction of thefirst pixel unit 01, but after the brightness of thefirst pixel unit 01 in the first display area AA1 is increased, the brightness of thefirst sub-pixel 011a borrowed by thesecond pixel unit 02 is obviously higher than the brightness of the otherfirst sub-pixels 011b and higher than the brightness of thesecond sub-pixel 021, so that the problem of bright lines caused by thefirst sub-pixel 011b occurs in the first display area AA1 and the second display area AA2, and the display effect of thedisplay panel 100 is affected.

In order to solve the above technical problem, the present invention provides a display panel and a display device. Embodiments of the display panel and the display device provided by the present invention will be described in detail below.

In this embodiment, please refer to fig. 3 and fig. 4, in which fig. 3 is a schematic diagram of a display panel structure according to the present invention, and fig. 4 is a partial enlarged view of W in fig. 3. Thedisplay panel 200 provided by the embodiment includes a display area AA, where the display area AA includes a first display area AA1 and a second display area AA 2; the first display area AA1 includes a plurality of first pixel cells 1, the second display area AA2 includes a plurality of second pixel cells 2, and the light transmittance of the first display area AA1 is greater than that of the second display area AA 2; the first pixel unit 1 adjacent to the second display area AA2 is a first transition pixel unit 10, and the second pixel unit 2 adjacent to the first display area AA1 is a second transition pixel unit 20; the first transition pixel unit 10 includes a plurality offirst sub-pixels 11 andauxiliary sub-pixels 12, thefirst sub-pixels 11 and theauxiliary sub-pixels 12 have different colors, theauxiliary sub-pixels 12 include at least twoauxiliary sub-sections 121, and the area of theauxiliary sub-sections 121 is smaller than that of thefirst sub-pixels 11, and the second transition pixel unit 20 includes a plurality ofsecond sub-pixels 21; the display area AA further includes a dummy pixel unit H including a plurality of sub-pixels H1 with different light emission colors, and the dummy pixel unit H includes anauxiliary sub-section 121 and asecond sub-pixel 21 adjacent to theauxiliary sub-section 121 and having a different color.

It is understood that the light transmittance of the first display area AA1 is greater than that of the second display area AA 2; the light transmittance of the first display area AA1 may be greater than that of the second display area AA2 by setting the density of thefirst pixel cells 01 in the first display area AA1 to be greater than that of thesecond pixel cells 02 in the second display area AA2, but the invention is not limited thereto, and the light transmittance of the first display area AA1 may be greater than that of the second display area AA2 in other manners. The first display area AA1 may be used for placing optical devices such as an image pickup device, but the present invention is not limited thereto.

Thedisplay panel 200 of the present embodiment further includes a dummy pixel unit H at the boundary between the first display area AA1 and the second display area AA2, where the dummy pixel unit H includes a plurality of sub-pixels H1 with different light emitting colors, and the dummy pixel unit H includes anauxiliary sub-portion 121 and asecond sub-pixel 21 adjacent to theauxiliary sub-portion 121 and having a different color. That is, at least one sub-pixel H1 in the same dummy pixel unit H is theauxiliary sub-portion 121, at least one sub-pixel H1 is thesecond sub-pixel 21, and theauxiliary sub-portion 121 and thesecond sub-pixel 21 in the same dummy pixel unit H are different in color. Since theauxiliary sub-pixel 12 includes at least twoauxiliary sub-portions 121, and the luminance of theauxiliary sub-portion 121 is only a part of the luminance of theauxiliary sub-pixel 12, and since the area of theauxiliary sub-portion 121 in the same first transition pixel unit 10 is smaller than the area of thefirst sub-pixel 11, that is, the light emitting area of theauxiliary sub-portion 121 is smaller than the light emitting area of thefirst sub-pixel 11, it can be further understood that the luminance of theauxiliary sub-portion 121 in the same first transition pixel unit 10 is smaller than the luminance of thefirst sub-pixel 11, as theauxiliary sub-portion 121 is provided as described above, the luminance of theauxiliary sub-portion 121 overlaps the luminances of the first pixel unit 1 and the second pixel unit 2 during displaying, and further the luminance of theauxiliary sub-portion 121 in the same virtual pixel unit H is similar to the luminance of thesecond sub-pixel 21 and to the luminance of, when a picture is displayed, the brightness of the virtual pixel unit H is similar to the brightness of other pixel units, so that the problem of bright lines at the junction of the first display area AA1 and the second display area AA2 is avoided, and the display uniformity of thedisplay panel 200 is improved.

Fig. 4 only illustrates that the first transition pixel unit 10 includes 2first sub-pixels 11 and oneauxiliary sub-pixel 12, and oneauxiliary sub-pixel 12 includes twoauxiliary sub-portions 121, the second transition pixel unit 20 includes 3second sub-pixels 21, and the virtual pixel unit H includes 3 sub-pixels H1 with different emission colors, but the present invention does not specifically limit the number of sub-pixels in the first transition pixel unit 10, the second transition pixel unit 20, and the virtual pixel unit H, and can be set according to an actual situation, which is not described in detail below.

In some alternative embodiments, continuing with fig. 3 and 4, the present embodiment provides thedisplay panel 200 in which the dummy pixel units H perform white display.

It is understood that the white light is synthesized by the light emitted from each of the red, green, and blue sub-pixels. The dummy pixel unit H includes a plurality of sub-pixels H1 with different emitting colors, i.e., red, green, and blue sub-pixels. Further, since the dummy pixel unit H includes theauxiliary sub-portion 121 and thesecond sub-pixel 21 adjacent to theauxiliary sub-portion 121 and having different colors, theauxiliary sub-portion 121 and thesecond sub-pixel 21 in the same dummy pixel unit H can be any two of a red sub-pixel, a green sub-pixel and a blue sub-pixel.

In some alternative embodiments, continuing with fig. 3 and 4, the present embodiment provides a display panel 200: theauxiliary sub-pixel 12 includes twoauxiliary sub-sections 121; in the same first transition pixel unit 10, theauxiliary sub-portions 121 are located at two sides of thefirst sub-pixel 11 along the direction that the first display area AA1 points to the second display area AA 2.

It can be understood that theauxiliary sub-pixel 12 includes twoauxiliary sub-portions 121, and the light-emitting luminance of eachauxiliary sub-portion 121 is equivalent to the light-emitting luminance of a part of theauxiliary sub-pixels 12, that is, the luminance of the sub-pixels in the first pixel unit 1 borrowed by the virtual pixel unit H can be reduced, so that the light-emitting luminance of theauxiliary sub-portion 121 in the same virtual pixel unit H can be similar to the light-emitting luminance of thesecond sub-pixel 21, and the display uniformity of thedisplay panel 200 can be improved. Further, in the same first transition pixel unit H, along the direction from the first display area AA1 to the second display area AA2, theauxiliary sub-portions 121 are located at two sides of thefirst sub-pixel 11. Due to the same first transition pixel unit H, the light emitting colors of theauxiliary sub-portion 121 and thefirst sub-pixel 11 are different, and theauxiliary sub-portion 121 is disposed on two sides of thefirst sub-pixel 11, so that the color light emitted by theauxiliary sub-pixel 12 can be further dispersed, and the problem that the color sub-pixel is visible at the boundary between the first display area AA1 and the second display area AA2 when a white picture is displayed in the prior art can be solved.

In the invention, the size of the area of theauxiliary sub-portion 121 in the sameauxiliary sub-pixel 12 is not specifically required, and fig. 4 only shows that the size of the area of theauxiliary sub-portion 121 in the sameauxiliary sub-pixel 12 is the same, but the size of the area of theauxiliary sub-portion 121 in the sameauxiliary sub-pixel 12 may also be set according to actual display requirements. When the areas of theauxiliary sub-portions 121 in the sameauxiliary sub-pixel 12 are the same, the light-emitting luminance of eachauxiliary sub-portion 121 is equal to 50% of the light-emitting luminance of theauxiliary sub-pixel 12, that is, the luminance of the sub-pixel in the first pixel unit 1 borrowed by the virtual pixel unit H can be reduced, so that the light-emitting luminance of theauxiliary sub-portion 121 in the same virtual pixel unit H can be similar to the light-emitting luminance of thesecond sub-pixel 21, and the problem that the color sub-pixel is visible at the boundary between the first display area AA1 and the second display area AA2 when a white picture is displayed in the prior art can be solved. And due to the area of eachauxiliary sub-portion 121, the device arrangement in thedisplay panel 200 and the process can be simplified.

In some alternative embodiments, shown in conjunction with fig. 3 and 5, fig. 5 is a further partial enlargement of W in fig. 3. Thedisplay panel 200 provided in this embodiment: theauxiliary sub-pixel 12 comprises threeauxiliary sub-portions 121, oneauxiliary sub-portion 121 is located between thefirst sub-pixel 11 and thesecond sub-pixel 21, twoauxiliary sub-portions 121 are located between thefirst sub-pixel 11 and the first pixel unit 1, and the auxiliary sub-pixels 12 are disposed around thefirst sub-pixel 11, in a direction in which the same first transition pixel unit 10 points along the first display area AA1 to the second display area AA 2.

It can be understood that theauxiliary sub-pixel 12 includes threeauxiliary sub-portions 121, and compared with theauxiliary sub-pixel 12 including twoauxiliary sub-portions 121, the luminance of eachauxiliary sub-portion 121 can be further reduced, that is, the luminance of the sub-pixel in the first pixel unit 1 borrowed by the virtual pixel unit H can be effectively reduced, the luminance of theauxiliary sub-portion 121 in the same virtual pixel unit H can be made to be similar to the luminance of thesecond sub-pixel 21, and the display uniformity of thedisplay panel 200 can be improved. Further, in a direction of the first display area AA1 pointing to the second display area AA2, oneauxiliary sub-section 121 is located between thefirst sub-pixel 11 and thesecond sub-pixel 21, and twoauxiliary sub-sections 121 are located between thefirst sub-pixel 11 and the first pixel unit 1 in the same first transition pixel unit H. Due to the same first transition pixel unit H, the light emitting colors of theauxiliary sub-portion 121 and thefirst sub-pixel 11 are different, and theauxiliary sub-portion 121 is disposed on two sides of thefirst sub-pixel 11, so that the color light emitted by theauxiliary sub-pixel 12 can be further dispersed, and the problem that the color sub-pixel is visible at the boundary between the first display area AA1 and the second display area AA2 when a white picture is displayed in the prior art can be solved.

In some alternative embodiments, shown in conjunction with fig. 3 and 6, fig. 6 is a further enlarged view of a portion W of fig. 3. Thedisplay panel 200 provided in this embodiment: theauxiliary sub-pixel 12 includes fourauxiliary sub-sections 121; in the same first transition pixel unit 10, theauxiliary sub-portions 121 are located on two sides of thefirst sub-pixel 11 along the first direction X, and theauxiliary sub-portions 121 are located on two sides of thefirst sub-pixel 11 along the second direction Y, where the first direction X intersects with the second direction Y. Optionally, the second direction Y is a direction in which the first display area AA1 points to the second display area AA 2.

It can be understood that theauxiliary sub-pixel 12 includes fourauxiliary sub-portions 121, and compared with theauxiliary sub-pixel 12 including twoauxiliary sub-portions 121, the luminance of eachauxiliary sub-portion 121 can be further reduced, that is, the luminance of the sub-pixel in the first pixel unit 1 borrowed by the virtual pixel unit H can be effectively reduced, the luminance of theauxiliary sub-portion 121 in the same virtual pixel unit H can be made to be similar to the luminance of thesecond sub-pixel 21, and the display uniformity of thedisplay panel 200 can be improved. Further, in a direction of the first display area AA1 pointing to the second display area AA2, oneauxiliary sub-section 121 is located between thefirst sub-pixel 11 and thesecond sub-pixel 21, and twoauxiliary sub-sections 121 are located between thefirst sub-pixel 11 and the first pixel unit 1 in the same first transition pixel unit H. Due to the same first transition pixel unit H, the light emitting colors of theauxiliary sub-portion 121 and thefirst sub-pixel 11 are different, and theauxiliary sub-portion 121 is disposed on two sides of thefirst sub-pixel 11, so that the color light emitted by theauxiliary sub-pixel 12 can be further dispersed, and the problem that the color sub-pixel is visible at the boundary between the first display area AA1 and the second display area AA2 when a white picture is displayed in the prior art can be solved.

In some alternative embodiments, shown in conjunction with fig. 3 and 7, fig. 7 is an enlarged view of a feature K in fig. 3. Thedisplay panel 200 provided in this embodiment: the second display region AA2 is disposed around the first display region AA1, a part of the first transition pixel units H includes twoauxiliary sub-pixels 12, anauxiliary sub-pixel 12a and anauxiliary sub-pixel 12b, the dummy pixel units Ha arranged in the first direction X includes theauxiliary sub-section 121a of theauxiliary sub-pixel 12a and thesecond sub-pixel 21 adjacent to theauxiliary sub-section 121a and having a different color, and the dummy pixel units Hb arranged in the second direction Y includes theauxiliary sub-section 121b of theauxiliary sub-pixel 12b and thesecond sub-pixel 21 adjacent to theauxiliary sub-section 121b and having a different color.

It can be understood that theauxiliary sub-section 121 of each of the partial first transition pixel units 10 borrows two virtual pixel units H, and the partial first transition pixel unit 10 includes twoauxiliary sub-pixels 12, anauxiliary sub-pixel 12a and anauxiliary sub-pixel 12b, the virtual pixel unit Ha arranged along the first direction X includes theauxiliary sub-section 121a of theauxiliary sub-pixel 12a, and thesecond sub-pixel 21 adjacent to theauxiliary sub-section 121a and having a different color, so that the luminance of the virtual pixel unit Ha arranged along the first direction X is similar to the luminance of other pixel units, and the problem of bright lines at the boundary between the first display area AA1 and the second display area AA2 in the first direction X is avoided; the dummy pixel unit Hb arranged in the second direction Y includes theauxiliary sub-section 121b of theauxiliary sub-pixel 12b, and thesecond sub-pixel 21 adjacent to theauxiliary sub-section 121b and having a different color. The brightness of the virtual pixel units Hb arranged along the second direction Y can be made to be similar to the brightness of other pixel units, so that the problem of bright lines at the junction of the first display area AA1 and the second display area AA2 in the second direction Y is avoided, and the display uniformity of thedisplay panel 200 is improved. Further, theauxiliary sub-segments 121a and 121b in the same first transition pixel unit 10 may be alternately arranged, so that the color light emitted by the first transition pixel unit 10 is dispersed, thereby avoiding the problem of color sub-pixel visibility. In fig. 7, only theauxiliary sub-pixel 12 includes fourauxiliary sub-portions 121, but the number of the auxiliary sub-portions of eachauxiliary sub-pixel 12 is not specifically required in the present invention, and may be set according to actual situations, and is not described in detail below.

In some alternative embodiments, continuing with fig. 3 to 6, the present embodiment provides a display panel 200: in the same first transition pixel unit 10, theauxiliary sub-portion 121 is electrically connected to the same pixel circuit (not shown).

It is understood that, due to the same first transition pixel unit 10, theauxiliary sub-pixel 12 includes a plurality ofauxiliary sub-portions 121, and the number of sub-pixels is increased, so that the number of data lines for providing display signals to the sub-pixels is increased, and the problem of decreasing the aperture ratio may be caused because the data lines are opaque. Therefore, the present application further defines the same first transition pixel unit 10, and theauxiliary sub-portion 121 is electrically connected to the same pixel circuit (not shown), so that the signals can be transmitted synchronously, and the influence of the increase of the number of data lines for transmitting signals to the sub-pixels in the subsequent period on the aperture ratio in the display area AA is reduced. Meanwhile, because the same first transition pixel unit 10 and theauxiliary sub-portion 121 are electrically connected to the same pixel circuit, the signal provided by the pixel circuit is the same as the signal provided by the pixel circuits of the remaining first sub-pixels 11 in the first transition unit 10, so that the light-emitting luminance of theauxiliary sub-portion 121 can be adjusted only by changing the area of theauxiliary sub-portion 121, and the light-emitting luminance of theauxiliary sub-pixel 12 can be controlled, thereby avoiding the problems that a bright line appears at the boundary between the first display area AA1 and the second display area AA2, and the color sub-pixels are visible.

In some alternative embodiments, and as shown in continued reference to fig. 8 and 9, fig. 8 is a further enlarged view of W in fig. 3, and fig. 9 is a further enlarged view of W in fig. 3. Thedisplay panel 200 provided in this embodiment: in the sameauxiliary sub-pixel 12, eachauxiliary sub-section 121 is connected by a connection portion L.

It is understood that, in the same first transition pixel unit 10, theauxiliary sub-pixel 12 includes a plurality ofauxiliary sub-portions 121, and theauxiliary sub-portions 121 are electrically connected to the same pixel circuit (not shown). It is further possible to connect each of theauxiliary sub-sections 121 in the sameauxiliary sub-pixel 12 via the connection section L. Further, the signals can be transmitted synchronously, so that the influence of the increase of the number of the data lines for transmitting the signals for the sub-pixels on the aperture ratio in the display area AA is reduced. In fig. 8, only one first transition pixel unit 10 is used, theauxiliary sub-pixel 12 includes twoauxiliary sub-portions 121, and the blockingsub-portions 121 are connected by providing one connecting portion L, in fig. 9, only one first transition pixel unit 10 is used, theauxiliary sub-pixel 12 includes fourauxiliary sub-portions 121, the fourauxiliary sub-portions 121 are connected at a time to form an accommodating space, and the first accommodating space can be used for accommodating thefirst sub-pixel 11. Therefore, in the direction perpendicular to thedisplay panel 200, the connection portion L and the first sub-pixel are not overlapped, and the problems of short circuit and the like between the connection portion L and the first sub-pixel can be avoided. The film structure and the material of the connecting part L are not required to be specific, and the connecting part L can be arranged according to the actual situation, and is not described in detail below.

In some alternative embodiments, shown in conjunction with fig. 8 and 10, fig. 10 is a cross-sectional view taken in the direction N-N' of fig. 8. Thedisplay panel 200 provided in this embodiment: theauxiliary sub-portion 121 includes ananode 313, and the connecting portion L is on the same layer as theanode 313.

Optionally, the display panel provided in this embodiment is an Organic Light-Emitting display panel (OLED), and the OLED display panel includes an array substrate, a pixel defining layer, a Light-Emitting layer, an encapsulation layer, a color resist layer, and a polarizer. In fig. 10, in order to visually describe the anode structure, only the structures of the light emitting layer 30, the array substrate TFT, and thesubstrate 00 are illustrated, wherein the light emitting layer 30 includes a plurality of organic light emitting devices 31, and the organic light emitting devices 31 are located in the opening area 41. Specifically, the organic light emitting device 31 includes acathode 311, ananode 313, and an organiclight emitting material 312 between thecathode 311 and theanode 313, the patternedanode 313 is disposed on the array substrate TFT, the organiclight emitting material 312 is formed on theanode 313 in the opening region 41 through an evaporation process, and then thecommon cathode 311 is disposed on a side of the organiclight emitting material 312 away from theanode 313. When a voltage is applied between theanode 313 and thecathode 311, the organiclight emitting material 312 emits visible light.

It is understood that theauxiliary sub-portion 121 includes theanode 313, and the connection portion L is in the same layer as theanode 313. That is, the anode of eachauxiliary sub-portion 121 may be electrically connected to each other by the connection portion L, and since theanode 313 is disposed on the array substrate TFT, the anode may be further connected to the same pixel driving circuit. Meanwhile, when theanode 313 is patterned, theanode 313 between adjacentauxiliary sub-portions 121 in the same first transition pixel unit 10 does not need to be etched, so that the anode 131 is connected, that is, the connection portion L and theanode 313 have the same layer, which also simplifies the process.

In some alternative embodiments, as shown in fig. 3 to fig. 6, the area of eachauxiliary sub-portion 121 of thedisplay panel 200 provided in the present embodiment is equal.

It is understood that the areas of theauxiliary sub-sections 121 are equal, that is, the light-emitting areas of theauxiliary sub-sections 121 are equal, so that the light-emitting luminance of eachauxiliary sub-section 121 is the same, and the light-emitting luminance of theauxiliary sub-sections 121 in theauxiliary sub-pixels 12 is prevented from being uneven, that is, the display uniformity of thedisplay panel 200 is further improved.

In some alternative embodiments, as shown in fig. 3, 4 and 6, thedisplay panel 200 provided in this embodiment has theauxiliary sub-pixel 12 with an area equal to or larger than the area of thefirst sub-pixel 11.

It is understood that, as shown in connection with fig. 4, when the area of theauxiliary sub-pixel 12 is equal to the area of thefirst sub-pixel 11. The first transitional pixel unit 10 includes a plurality of first sub-pixels 11 and auxiliary sub-pixels 12, and theauxiliary sub-pixel 12 includes twoauxiliary sub-portions 121, where the area of theauxiliary sub-portion 121 is equal to half of the area of oneauxiliary sub-pixel 12, that is, the light-emitting luminance of oneauxiliary sub-portion 121 is half of the light-emitting luminance of theauxiliary sub-pixel 12, and the light-emitting luminance of oneauxiliary sub-portion 121 is half of the light-emitting luminance of thefirst sub-pixel 11. Because the brightness of the dispersed auxiliary sub-pixels 12 is reduced, the brightness of theauxiliary sub-portion 121 in the virtual pixel unit H can be similar to the brightness of thesecond sub-pixel 21, and further the brightness of theauxiliary sub-portion 121 in the same virtual pixel unit H can be similar to the brightness of thesecond sub-pixel 21, when a picture is displayed, the brightness of the virtual pixel unit H is similar to the brightness of other pixel units, the problem that a bright line appears at the boundary between the first display area AA1 and the second display area AA2 is avoided, and the display uniformity of thedisplay panel 200 is improved.

When the area of theauxiliary sub-pixel 12 is larger than the area of thefirst sub-pixel 11, referring to fig. 6, only taking the example that the area of theauxiliary sub-pixel 12 is twice as large as the area of thefirst sub-pixel 11 as shown in fig. 6, since theauxiliary sub-pixel 12 includes fourauxiliary sub-portions 121, the area of theauxiliary sub-portion 121 is equal to half of the area of oneauxiliary sub-pixel 12, that is, the light-emitting luminance of oneauxiliary sub-portion 121 is half of the light-emitting luminance of theauxiliary sub-pixel 12, and the light-emitting luminance of oneauxiliary sub-portion 121 is half of the light-emitting luminance of the first sub-pixel. Because the brightness of the dispersed auxiliary sub-pixels 12 is reduced, the brightness of theauxiliary sub-portion 121 in the virtual pixel unit H can be similar to the brightness of thesecond sub-pixel 21, and further the brightness of theauxiliary sub-portion 121 in the same virtual pixel unit H can be similar to the brightness of thesecond sub-pixel 21, when a picture is displayed, the brightness of the virtual pixel unit H is similar to the brightness of other pixel units, the problem that a bright line appears at the boundary between the first display area AA1 and the second display area AA2 is avoided, and the display uniformity of thedisplay panel 200 is improved.

Optionally, the area of theauxiliary sub-pixel 12 is S1, the area of thefirst sub-pixel 11 is S2, the area of thefirst sub-pixel 11 is S2 is S1 is 3S2, when the area S1 of theauxiliary sub-pixel 12 is smaller than the area S2 of thefirst sub-pixel 11, since theauxiliary sub-pixel 12 needs to be divided into a plurality ofauxiliary sub-portions 121, the luminance of eachauxiliary sub-portion 121 is too small, the luminance of theauxiliary sub-portion 121 in the same virtual pixel unit H is lower than the luminance of thesecond sub-pixel 21, and the area S1 of theauxiliary sub-pixel 12 needs to be ensured not to be smaller than the area S2 of thefirst sub-pixel 11. Meanwhile, when the area S1 of theauxiliary sub-pixel 12 is larger than 3 times the area S2 of thefirst sub-pixel 11, if the number of theauxiliary sub-portions 121 into which theauxiliary sub-pixel 12 is divided is small, the luminance of theauxiliary sub-portion 121 in the same virtual pixel unit H is higher than that of thesecond sub-pixel 21, that is, the problem that the display effect of thedisplay panel 200 is affected by the split screen due to the bright line existing at the boundary between the first display area AA1 and the second display area AA2 is not solved. The present invention only takes the area of theauxiliary sub-pixel 12 and the area of thefirst sub-pixel 11 as an example, but is not limited thereto, and may be specifically configured according to the actual situation, and will not be described in detail below.

In some alternative embodiments, in combination with thedisplay panel 200 shown in fig. 3 to 6, the present embodiment provides: the density of the first transition pixel unit 10 is greater than the density of the first pixel units 1 other than the first transition pixel unit 10.

It can be understood that, since the first transition pixel unit 10 includes a plurality of first sub-pixels 11 and auxiliary sub-pixels 12, the colors of the first sub-pixels 11 are different from the colors of theauxiliary sub-pixels 12, the auxiliary sub-pixels 12 include at least twoauxiliary sub-portions 121, and a plurality of additionalauxiliary sub-portions 121 are provided, which corresponds to increasing the number of sub-pixels in the first transition pixel unit 10, and if the number is increased in a unit area, the density of the first transition pixel unit 10 is greater than the density of the first pixel units 1 except the first transition pixel unit 10, and further since the luminance of oneauxiliary pixel 12 is dispersed into the plurality ofauxiliary sub-portions 121, the luminance of theauxiliary sub-portions 121 can be reduced, and further the luminance of theauxiliary sub-portions 121 in the virtual pixel unit H can be similar to the luminance of thesecond sub-pixel 21, thereby avoiding the problem that a bright line appears at the boundary between the first display area AA1 and the second display area AA2, the display uniformity of thedisplay panel 200 is improved.

The present invention further provides adisplay device 300 including thedisplay panel 200 according to any of the above embodiments of the present invention.

the display panel and the display device provided by the invention comprise display areas, wherein each display area comprises a first display area and a second display area, the light transmittance of the first display area is greater than that of the second display area, and in order to realize the brightness uniformity of the first display area and the second display area, the brightness of sub-pixels in the first display area is set to be higher than that of sub-pixels in the second display area, but bright lines can appear at the junction of the first display area and the second display area. Therefore, the first transition pixel unit comprises a plurality of first sub-pixels and auxiliary sub-pixels, the colors of the first sub-pixels and the auxiliary sub-pixels are different, the auxiliary sub-pixels comprise at least two auxiliary sub-portions, the area of the auxiliary sub-portions is smaller than that of the first sub-pixels, and the second transition pixel unit comprises a plurality of second sub-pixels; the display area further comprises a virtual pixel unit, the virtual pixel unit comprises sub-pixels with different light-emitting colors, and the virtual pixel unit comprises an auxiliary sub-portion and a second sub-pixel which is adjacent to the auxiliary sub-portion and has different colors. Because the auxiliary sub-pixel comprises at least two auxiliary sub-portions, the area of the auxiliary sub-portions is smaller than that of the first sub-pixel, the brightness of the auxiliary sub-portions only partially assists the brightness of the sub-pixels, and the light-emitting brightness of the auxiliary sub-portions is smaller than that of the first sub-pixel, the brightness of the auxiliary sub-portions can be compensated to superpose the brightness of the first pixel unit and the brightness of the second pixel unit during display, so that the light-emitting brightness of the auxiliary sub-portions in the same virtual pixel unit is similar to that of the second sub-pixel and also similar to that of the first sub-pixel, when a picture is displayed, the brightness of the virtual pixel unit is similar to that of other pixel units, the problem that bright lines can appear at the junction of the first display area and the second display area is avoided, and the display uniformity of the display panel is improved.
