Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

To illustrate the features of the embodiments of the present invention, prior art will be described before the embodiments of the present invention are described in detail. As shown in fig. 1, a plurality of sub-pixels are defined by a scanning line 2 'and a data line (not shown in fig. 1) in a crossing manner, each sub-pixel is provided with a switch tube, a control end of the switch tube is connected to a corresponding scanning line 2', when the display panel is scanned, the scanning line 2 'is sequentially provided with a conducting level, the scanning line 2' controls the switch tube corresponding to a row of sub-pixels to be conducted, the data line charges the sub-pixels of the row through the switch tube, for example, for the liquid crystal display panel, each sub-pixel is provided with a pixel electrode correspondingly, a source electrode of the switch tube is connected to a corresponding data line, a drain electrode of the switch tube is connected to a corresponding pixel electrode, when the switch tube is conducted, a data voltage on the data line is transmitted to the corresponding pixel electrode through the switch tube, the pixel electrode is charged, so that the pixel electrode is charged to a corresponding voltage, the liquid crystal display panel further comprises a common electrode and a liquid crystal, the liquid crystal is deflected under an electric field between the common electrode and the pixel electrode to realize gray scale control of the sub-pixels. However, the number of sub-pixels connected to one scan line 2 'in the special-shaped display area 12' is small, and the number of sub-pixels connected to one scan line 2 'in the normal display area 11' is large, so that the scan line 2 'of the special-shaped display area 12' has a small load, so that the switching tube in the special-shaped display area 12 'has a fast turn-on time, the time for charging the pixel electrode in the special-shaped display area 12' is long, and the scan line 2 'of the normal display area 11' has a large load, so that the switching tube in the special-shaped display area 12 'has a slow turn-on time, and the time for charging the pixel electrode in the normal display area 11' is short. This results in the luminance of the special-shaped display area 12 'being greater than the luminance of the normal display area 11' under the same screen.

As shown in fig. 2, fig. 3 and fig. 4, fig. 2 is a schematic structural diagram of a display panel in an embodiment of the present invention, fig. 3 is a schematic partial enlarged structural diagram of a first region in fig. 2, and fig. 4 is a schematic partial enlarged structural diagram of a second region in fig. 2, where an embodiment of the present invention provides a display panel, including: adisplay area 1, thedisplay area 1 including anormal display area 11 and anirregular display area 12, thenormal display area 11 and theirregular display area 12 being adjacent in the first direction h1, a width of theirregular display area 12 in the second direction h2 being smaller than a width of thenormal display area 11 in thesecond direction h 2; thedisplay region 1 includes a plurality of sub-pixels defined by a plurality ofscan lines 2 and a plurality ofdata lines 3 which are cross-insulated, the plurality ofscan lines 2 extending in the second direction h2 and arranged in the first direction h1, and the plurality ofdata lines 3 extending in the first direction h1 and arranged in thesecond direction h 2; the special-shaped display area 12 comprises afirst area 41, thenormal display area 11 comprises asecond area 42, and the aperture ratio of thefirst color sub-pixels 51 in thefirst area 41 is smaller than the aperture ratio of thefirst color sub-pixels 51 in thesecond area 42.

Specifically, the higher the aperture ratio, the higher the efficiency of light passing. Setting the aperture ratio of thefirst color sub-pixel 51 in the special-shaped display area 12 to be smaller than the aperture ratio of thefirst color sub-pixel 51 in thenormal display area 11, under the same picture, since the aperture ratio of thefirst color sub-pixel 51 in the special-shaped display area 12 is smaller than the aperture ratio of thefirst color sub-pixel 51 in thenormal display area 11, the difference of the aperture ratios of the first color sub-pixels reduces the brightness of the special-shaped display area 12 relative to thenormal display area 11, thereby reducing the brightness difference between the special-shaped display area and the normal display area. In addition, in the embodiment of the invention, the reduction of the brightness difference between the special-shaped display area and the normal display area is realized by changing the aperture ratio of the sub-pixels with the same color, and the influence on the chromaticity of the display picture is small.

It should be noted that the aperture ratio of the white sub-pixel W in the normal display area illustrated in fig. 4 is the same as the aperture ratios of the other color sub-pixels, but the embodiment of the present invention is not limited to the relationship between the aperture ratio of the white sub-pixel W and the aperture ratios of the other color sub-pixels in the normal display area, for example, in an achievable implementation, the aperture ratio of the white sub-pixel W is smaller than the aperture ratios of the other color sub-pixels, so that the overall display luminance can be improved by the white sub-pixel W, but the chromaticity of the display screen is not greatly affected by the larger aperture ratio of the white sub-pixel W.

Optionally, the aperture ratio of any one of thefirst color sub-pixels 51 in thefirst region 41 is smaller than the aperture ratio of any one of thefirst color sub-pixels 51 in thesecond region 42.

Specifically, setting the aperture ratio of all thefirst color sub-pixels 51 in thefirst region 41 to be smaller than the aperture ratio of all thefirst color sub-pixels 51 in thesecond region 42 can make the display brightness in thefirst region 41 and thesecond region 42 more uniform. When the driving chip is driven by the data line, the corresponding data voltage is required to be provided according to the aperture ratio relation of the sub-pixels, and because the sub-pixels with the same color all have the aperture ratio change, the design logic of the driving chip is simpler.

Alternatively, as shown in fig. 2, 5 and 6, fig. 5 is another schematic partial enlarged structure of the first region in fig. 2, and fig. 6 is another schematic partial enlarged structure of the second region in fig. 2, where the plurality of sub-pixels include a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B; thefirst color sub-pixel 51 is a green sub-pixel G.

Specifically, among the red, green, and blue sub-pixels R, G, and B, the green sub-pixel G contributes most to the display luminance, and therefore, taking the green sub-pixel G as thefirst color sub-pixel 51 can reduce the luminance difference between theirregular display region 12 and thenormal display region 11 at the expense of a small aperture ratio.

Alternatively, as shown in fig. 2, 3 and 4, the plurality of sub-pixels includes a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B and a white sub-pixel W; thefirst color sub-pixel 51 is a white sub-pixel W.

Specifically, the white subpixel W is used to increase the luminance of the display region, and the white subpixel W contributes most to the display luminance among the red subpixel R, the green subpixel G, the blue subpixel B, and the white subpixel W, so that the luminance difference between theirregular display region 12 and thenormal display region 11 can be reduced by using the white subpixel W as thefirst color subpixel 51 at the expense of a small aperture ratio. In addition, the white subpixel W is used only for enhancing luminance, and color display of the pixel is realized by the red subpixel R, the green subpixel G, and the blue subpixel B, and thus, the aperture ratio of the white subpixel W is reduced, and luminance may be reduced, but chromaticity of color display is not adversely affected.

Alternatively, as shown in fig. 2, 7 and 8, fig. 7 is another partial enlarged structural diagram of the first region in fig. 2, and fig. 8 is another partial enlarged structural diagram of the second region in fig. 2, where the aperture ratio of any onesecond color sub-pixel 52 in thefirst region 41 is smaller than the aperture ratio of any onesecond color sub-pixel 52 in thesecond region 42; thesecond color sub-pixel 52 is a green sub-pixel G.

Specifically, if the white sub-pixel is used as thefirst color sub-pixel 51, and the luminance approaches between the special-shapeddisplay region 12 and thenormal display region 11 cannot be adjusted, the green sub-pixel G can be further used as thesecond color sub-pixel 52, and the aperture ratio of thesecond color sub-pixel 52 in thefirst region 41 is smaller than the aperture ratio of thesecond color sub-pixel 52 in thesecond region 42, so as to further reduce the luminance difference between the special-shapeddisplay region 12 and thenormal display region 11.

Alternatively, as shown in fig. 2 and 9, fig. 9 is a partial enlarged structural diagram of the third area and the fourth area in fig. 2, the special-shapeddisplay area 12 includes athird area 43 located on the side of thefirst area 41 close to thenormal display area 11, and thethird area 43 is adjacent to thenormal display area 11; thenormal display area 11 comprises afourth area 44 located on a side of thesecond area 42 adjacent to the shapeddisplay area 12, thefourth area 44 being adjacent to the shapeddisplay area 12; the third andfourth regions 43 and 44 include a plurality offirst pixel groups 61 and a plurality ofsecond pixel groups 62, an aperture ratio of any one white subpixel W in eachfirst pixel group 61 is smaller than an aperture ratio of any one white subpixel W in eachsecond pixel group 62, and eachfirst pixel group 61 and eachsecond pixel group 62 are alternately arranged in thefirst direction h 1.

Specifically, thethird region 43 and thefourth region 44 are boundary regions of the special-shapeddisplay region 12 and thenormal display region 11, in order to avoid that the aperture ratios of all the white sub-pixels in the special-shaped display region are smaller than the aperture ratios of all the white sub-pixels in the normal display region, thereby causing a significant display boundary, thefirst pixel group 61 and thesecond pixel group 62 which are alternately arranged in the first direction h1 are arranged in the boundary region of the special-shapeddisplay region 12 and thenormal display region 11, and the aperture ratio of the white sub-pixel W in thefirst pixel group 61 is smaller than the aperture ratio of the white sub-pixel W in thesecond pixel group 62, so that thethird region 43 and thefourth region 44 are used as transition regions between thefirst region 41 and thesecond region 42, thereby avoiding abrupt picture changes at the boundary of the special-shapeddisplay region 12 and thenormal display region 11, and improving the visual effect during display.

As shown in fig. 2, 10 and 11, fig. 10 is another partial enlarged schematic structural diagram of the first region in fig. 2, and fig. 11 is another partial enlarged structural diagram of the second region in fig. 2, where the display panel is a liquid crystal display panel, and the liquid crystal display panel includes ablack matrix 7; the area of the black matrix corresponding to any one of the white subpixels W in thefirst region 41 is larger than the area of theblack matrix 7 corresponding to any one of the white subpixels W in thesecond region 42.

Specifically, in the liquid crystal display panel, theblack matrix 7 is provided for shielding thescanning line 2, thedata line 3, the thin film transistor, and the like, and theblack matrix 7 is provided with a hollow area (i.e., an opening of a sub-pixel) at a position of each sub-pixel, so that setting the aperture ratio of the white sub-pixel W in thefirst area 41 to be smaller than the aperture ratio of the white sub-pixel W in thesecond area 42 can be achieved by changing the area of theblack matrix 7 corresponding to the sub-pixel.

Alternatively, as shown in fig. 2, 10 and 11, the display panel includes asub-pixel region 8 corresponding to each sub-pixel, a thin film transistor 9 and apixel electrode 10, where eachsub-pixel region 8 is defined by intersecting thescan line 2 and thedata line 3, the thin film transistor 9 is connected to thecorresponding pixel electrode 10, it should be noted that the shape of thepixel electrode 10 in the drawings is only schematic, and the shape of thepixel electrode 10 in the embodiments of the present invention is not limited, for example, in other realizable embodiments, the pixel electrode is a strip electrode; in thefirst region 41, a corresponding thin film transistor 9, a correspondingpixel electrode 10, and a thin film transistor 9 corresponding to an adjacent sub-pixel are provided in a sub-pixel region corresponding to each white sub-pixel W, and the adjacent sub-pixel is a sub-pixel of a color other than the white sub-pixel W.

Specifically, since the opening area corresponding to the white sub-pixel W in thefirst region 41 is smaller, the thin film transistor 9 corresponding to the adjacent green sub-pixel G can be disposed in thesub-pixel region 8 corresponding to the white sub-pixel W to save the space of the green sub-pixel G, so that the green sub-pixel G can be designed with a larger opening area to meet the higher chromaticity requirement.

Alternatively, as shown in fig. 2, 3 and 4, among the two rows and four columns of sub-pixels, among the first row of pixels in the first direction h1, four sub-pixels arranged in the second direction h2 are a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B and a white sub-pixel W in order, and among the second row of pixels in the first direction h1, four sub-pixels arranged in the second direction h2 are a blue sub-pixel B, a white sub-pixel W, a red sub-pixel R and a green sub-pixel G in order.

Alternatively, as shown in fig. 2 and 9, the shapeddisplay area 12 includes athird area 43 located on a side of thefirst area 41 close to thenormal display area 11, thethird area 43 being adjacent to thenormal display area 11; thenormal display area 11 comprises afourth area 44 located on a side of thesecond area 42 adjacent to the shapeddisplay area 12, thefourth area 44 being adjacent to the shapeddisplay area 12; thethird region 43 and thefourth region 44 include a plurality offirst pixel groups 61 and a plurality ofsecond pixel groups 62, an aperture ratio of any one white subpixel W in eachfirst pixel group 61 is smaller than an aperture ratio of any one white subpixel W in eachsecond pixel group 62, and eachfirst pixel group 61 and eachsecond pixel group 62 are alternately arranged in thefirst direction h 1; eachfirst pixel group 61 is two adjacent rows of sub-pixels, and eachsecond pixel group 62 is two adjacent rows of sub-pixels.

Specifically, in the structure shown in fig. 9, every two rows have the same arrangement of sub-pixels, and therefore, when thefirst pixel group 61 and thesecond pixel group 62 in the transition region are provided, in order to accommodate the arrangement of sub-pixels that repeats every two rows, eachfirst pixel group 61 is provided as two adjacent rows of sub-pixels, and eachsecond pixel group 62 is provided as two adjacent rows of sub-pixels, so that, in the transition region, corresponding to the arrangement of sub-pixels, the white sub-pixel W in two adjacent rows of sub-pixels has a smaller opening area, the white sub-pixel W in the other adjacent two rows of sub-pixels has a smaller opening area, and so on, the transition region is implemented.

Alternatively, as shown in fig. 2, the display panel includes two shapeddisplay areas 12 arranged in thesecond direction h 2.

In particular, the non-display area between the two shapeddisplay areas 12 is used to set other elements in the display device, such as a headphone, a camera, etc., to improve the screen occupation ratio of the display device.

In the display device in the embodiment of the invention, the aperture ratio of the first color sub-pixel in the special-shaped display area is set to be smaller than the aperture ratio of the first color sub-pixel in the normal display area, and under the same picture, because the aperture ratio of the first color sub-pixel in the special-shaped display area is smaller than the aperture ratio of the first color sub-pixel in the normal display area, the difference of the aperture ratios of the first color sub-pixels reduces the brightness of the special-shaped display area relative to the normal display area, thereby reducing the brightness difference between the special-shaped display area and the normal display area.
