It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Fig. 1 is a schematic structural diagram of a display panel provided in the prior art. Referring to fig. 1, the display panel includes a display region 10 ' and a non-display region 20 ' surrounding the display region 10 '; the display area 10' is in the shape of a parallelogram; the display region 10 'includes a plurality of rows and columns of sub-pixels 30' and a plurality of data lines 40 ', and each column of sub-pixels 30' is aligned in the row direction, and each data line 40 'connects one column of sub-pixels 30'. However, the applicant found that when the data lines 40 'are connected to the driving chip 50' through the fan-out traces 60 ', there are a partial number of data lines 40' which need to occupy the right bezel for routing, and therefore, the right bezel is wide in width and it is difficult to implement a narrow bezel.

In view of the above, an embodiment of the present invention provides a display panel, including: a display area and a non-display area surrounding the display area;

the display area comprises a first side and a second side which are oppositely arranged, and a third side and a fourth side which are oppositely arranged; the first edge is parallel to the second edge; the third edge is respectively connected with the first edge and the second edge; the fourth edge is respectively connected with the first edge and the second edge; the included angle between the third edge and the first edge is an acute angle, and the included angle between the fourth edge and the first edge is an obtuse angle;

the display area comprises a plurality of rows of sub-pixels, and the adjacent two rows of sub-pixels are staggered by a preset distance delta x in the row direction; wherein the row direction is parallel to the first edge;

the slope of the extending direction of each signal line is h/delta x, wherein h is the height of the sub-pixels along the column direction; the extending direction of the signal line is the direction of the connection line of the sub-pixels connected with the signal line.

The above is the core idea of the present invention, and the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the embodiments of the present invention.

Fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention. Referring to fig. 2, the display panel includes: adisplay area 10 and anon-display area 20 surrounding thedisplay area 10; thedisplay area 10 comprises afirst side 11 and asecond side 12 which are oppositely arranged, and athird side 13 and afourth side 14 which are oppositely arranged; thefirst edge 11 is parallel to thesecond edge 12; thethird side 13 is connected to thefirst side 11 and thesecond side 12, respectively; thefourth side 14 is connected to thefirst side 11 and thesecond side 12, respectively; the included angle between thethird edge 13 and thefirst edge 11 is an acute angle, and the included angle between thefourth edge 14 and thefirst edge 11 is an obtuse angle; thedisplay area 10 includes a plurality of rows of sub-pixels P, and two adjacent rows of sub-pixels P are staggered by a preset distance Δ x in the row direction; wherein the row direction is parallel to thefirst side 11; a plurality ofsignal lines 40, wherein the slope of the extending direction Y of eachsignal line 40 is h/Δ x, wherein h is the height of the sub-pixel P along the column direction; the extending direction Y of thesignal line 40 is the direction in which the connection lines of the sub-pixels P connected thereto are located.

Specifically, the slope of the third side and the slope of the fourth side may be the same or different, and those skilled in the art may set the slope according to actual situations, and the slope is not limited herein.

Specifically, the sub-pixels P in two adjacent rows are shifted by the predetermined distance Δ x in the row direction, which means that two adjacent sub-pixels P are shifted in the row direction among the plurality of sub-pixels P connected to thesame signal line 40. The direction in which the connection lines of the sub-pixels P connected to thesame signal line 40 are located here refers to the direction in which the connection lines of the same point (shown in the upper right corner in fig. 2) of each sub-pixel P are located.

It can be understood that, compared to the case that the two adjacent rows of sub-pixels P are aligned in the row direction as shown in fig. 1, by arranging the two adjacent rows of sub-pixels P to be staggered by the preset distance Δ x in the row direction, the extending direction of thesignal line 40 can be made closer to the direction of thethird side 13 or thefourth side 14, so that the number of sub-pixels P connected to thesignal line 40 close to thethird side 13 and thesignal line 40 close to thefourth side 14 is made larger, and thus, when each sub-pixel P is connected to thecorresponding signal line 40, the total number of requiredsignal lines 40 is reduced. For example, referring to fig. 1 and fig. 2, in fig. 1, the direction of thesignal line 40 is perpendicular to the row direction, the number of thesignal lines 40 is 34, in fig. 2, the direction of thesignal line 40 is parallel to thethird side 13 and thefourth side 14, and the number of thesignal lines 40 is 30, when thesignal lines 40 are connected to thedriving chip 50 through the connectingtrace 60, all thesignal lines 40 are located in thedisplay area 10, and the right frame (the portion connected to thefourth side 14 in the non-display area 20) does not have to reserve positions for thesignal lines 40, so that the width of the right frame can be reduced, and the screen occupation ratio can be improved. In addition, if onedriving chip 50 is needed to provide signals for thesignal lines 40, the number of thesignal lines 40 is reduced, so that the occupation of pins on thedriving chip 50 can be reduced; if a plurality ofdriving chips 50 are needed to provide signals for thesignal lines 40, the number of thesignal lines 40 is reduced, which is beneficial to reducing the number of pins on eachdriving chip 50, or reducing the amount of thedriving chips 50 required, thereby reducing the cost.

In the display panel provided by the embodiment of the invention, thedisplay area 10 includes a plurality of rows of sub-pixels P and a plurality ofsignal lines 40, a preset distance Δ x is staggered in the row direction by setting two adjacent rows of sub-pixels P, and the slope of the extending direction Y of eachsignal line 40 is h/Δ x, wherein h is the height of the sub-pixels P in the column direction, and the extending direction Y of thesignal line 40 is the direction of the connecting line of the sub-pixels P connected with thesignal line 40, so that the extending direction Y of thesignal line 40 is close to the straight line direction of thethird edge 13 and thefourth edge 14 of thedisplay area 10, thus the number of thesignal lines 40 can be reduced, the area of the frame area which needs to be reserved for the routing of thesignal line 40 is reduced, and the effects of reducing the frame width and improving the screen occupation ratio are achieved.

Specifically, thedisplay area 10 may be implemented in various forms, and those skilled in the art may set the form according to the actual situation, and the form is not limited herein. Several typical examples of thedisplay area 10 will be described below.

Referring first to fig. 2, thedisplay area 10 may alternatively be a parallelogram. Thus, the number of the sub-pixels P in each row of the sub-pixels P can be the same, which is beneficial to realizing that all thesignal lines 40 are located in the display area.

When thedisplay area 10 is a parallelogram, optionally, with continued reference to fig. 2, the shape of the sub-pixel P is rectangular; the value range of Δ x is:

wherein h is the height of the subpixel P in the column direction; theta is an included angle between thethird side 13 and thefirst side 11; w is the width of the portion of thenon-display area 20 connected to thethird side 13; w is a pitch betweenadjacent signal lines 40 in the non-display region, the pitch including a line width and a line distance of thesignal lines 40; d is the width of the sub-pixel P unit along the row direction; n is the number of rows of the sub-pixel P. It should be noted that, the width of the portion of thenon-display area 20 connected to thethird side 13 is a vertical distance from the third side to the edge of the display panel. The width between theadjacent signal lines 40 in the non-display area described herein refers to a vertical distance between the adjacent signal lines.

When Δ x ≠ h/| tan θ |, the extending direction Y of thesignal line 40 is not completely parallel to thethird side 13,

specifically, thenon-display area 20 of the display panel includes an upper frame (a portion of thenon-display area 20 connected to the first edge 11) and a lower frame (a portion of thenon-display area 20 connected to the first edge 12) that are disposed opposite to each other, and further includes a left frame (a portion of thenon-display area 20 connected to the third edge 13) and a right frame (a portion of thenon-display area 20 connected to the fourth edge 14) that are disposed opposite to each other, the upper frame connects the left frame and the right frame, and the lower frame connects the left frame and the right frame. Generally, circuit elements known to those skilled in the art, such as an electrostatic protection circuit, are disposed on the left frame and/or the right frame, and therefore, the left frame and the right frame each have a certain width W, that is, in order to dispose necessary circuit elements, the width of the left frame and the right frame of the display panel is at least W, and within the width W, in theory, W/W signal lines 40 may be disposed.

It should be understood that, for convenience of drawing, it is only exemplarily shown in fig. 1 that the arrangement manner of each column of sub-pixels 30 ' aligned in the row direction enables four signal lines 40 ' to be located in the right frame, but in the actual manufacturing of the display panel, the arrangement manner of each column of sub-pixels 30 ' aligned in the row direction enables the number of signal lines 40 ' routed in the right frame to be much larger than W/W, that is, the right frame needs to be widened to provide space for routing the signal lines 40 ' on the basis of the width W of the right frame. However, in the present application, by controlling the number of thesignal lines 40 that need to be routed on the left frame or the right frame to be less than or equal to W/W, it is avoided that the left frame or the right frame is widened again on the basis that the widths of the left frame and the right frame are W. Thus, the number ofsignal lines 40 connecting the sub-pixels P is theoretically at most m + W/W, where m signallines 40 are located in thedisplay region 10, W/W signal lines 40 are located in the left frame region or the right frame region, and m is the number of sub-pixels P in each row of sub-pixels P. Further, it is also understood that the width W betweenadjacent signal lines 40 may be minimized to make the value of W/W large, under the precondition and conditions of process allowance.

For example, fig. 3 is a schematic structural diagram of another display panel provided in an embodiment of the present invention. Referring to fig. 2 and 3, it can be understood that, as the extending direction Y of thesignal line 40 is closer to the direction in which the third side 13 (or the fourth side 14) is located, the greater the number of sub-pixels P connected to thesignal line 40 near thethird side 13 and thefourth side 14, the fewer the total number ofsignal lines 40 required for the plurality of rows of sub-pixels P of theentire display area 10. Illustratively, the extending direction Y of thesignal lines 40 in fig. 2 is closer to the direction of thethird side 13 than the extending direction Y of thesignal lines 40 in fig. 3, and the number of thesignal lines 40 in fig. 2 is smaller than that of thesignal lines 40 in fig. 3. It can also be understood that, with continued reference to fig. 2, when the extending direction Y of thesignal line 40 is not completely parallel to thethird side 13, a partial number of thesignal lines 40 may be located in the left frame (or the right frame), but since the number of thesignal lines 40 located in the left frame (or the right frame) is less than or equal to W/W, thesignal lines 40 located in the left frame (or the right frame) may not cause the left frame (or the right frame) to widen.

It should be noted that, with reference to fig. 3, since thedisplay area 10 is irregular, a part of the same sub-pixel P (regular rectangular sub-pixel) may be located in thedisplay area 10, and another part of the same sub-pixel P is located in thenon-display area 20, and the sub-pixel P may be referred to as an edge sub-pixel. In the process of manufacturing the display panel, the edge sub-pixels in thenon-display area 20 may not be manufactured, or may be manufactured normally, as shown in fig. 3, the portion in thenon-display area 10 is covered by the black matrix.

Preferably, referring to fig. 2, when Δ x is h/| tan θ |, the extending direction Y of thesignal line 40 is parallel to the direction of the third side 13 (or the fourth side 14), the number of the sub-pixels P connected to eachsignal line 40 is equal to the number of the rows of the sub-pixels P in thedisplay area 10, all thesignal lines 40 are located in thedisplay area 10, and neither the left frame nor the right frame has to reserve space for routing the signal lines 40, so that the width of the frame can be reduced to the maximum extent.

About the formula

Principle of (1)To solve this problem, as can be seen from fig. 2 and 3, in fig. 2, Δ x is h/| tan θ |, the first row of sub-pixels P (the row of sub-pixels closest to the second edge 12) and the last row of sub-pixels P (the row of sub-pixels closest to the first edge 11) are staggered by (N-1) × h/| tan θ |, and the first sub-pixel P in the first row of sub-pixels P (for example, the sub-pixel labeled 1 in the first row of fig. 2) and the first sub-pixel P in the last row of sub-pixels P (for example, the sub-pixel labeled 1 in the last row of fig. 2) are connected to thesame signal line 40. When Δ x ≠ h/| tan θ |, which can be written as Δ x ═ htan θ - δ, the first row of sub-pixels P and the last row of sub-pixels P are shifted by (N-1) × (h/| tan θ | + δ), let ((N-1) × δ)/d calculate the number of sub-pixels P shifted between the first sub-pixel P in the last row of sub-pixels P (e.g., the sub-pixel in the last row of fig. 3 labeled 3) and the first sub-pixel P in the first row (e.g., the sub-pixel in the first row of fig. 3 labeled 1), the sub-pixel P that is shifted cannot be connected to thesame signal line 40 as the sub-pixel P in the last row of sub-pixels P, thesignal line 40 connected to the sub-pixel P that is shifted needs to be routed on the border (e.g., the signal line connected to the sub-pixels labeled 1 and 2 in the first row of fig. 3 needs to be on the left border), the value range of delta can be reversely deduced by making ((N-1) multiplied by delta)/d less than W/W, and then the value range of delta x is reversely deduced.

Next, optionally, thethird side 13 and thefourth side 14 are both oblique lines, and the side length of thefirst side 11 is greater than the side length of thesecond side 12. For example, fig. 4 is a schematic structural diagram of another display panel provided in the embodiment of the present invention.

When the length of thefirst side 11 is longer than that of thesecond side 12, optionally, the shape of the sub-pixel P is rectangular; the value range of Δ x is:

wherein h is the height of the subpixel P in the column direction; theta is the included angle between thethird side 13 and the first side 11 (or theta is the included angle between thefourth side 14 and the first side 11); w is the width of the portion of thenon-display area 20 connected to thethird side 13; w is a pitch betweenadjacent signal lines 40 in the non-display region, the pitch including a line width and a line distance of the signal lines 40; d is the width of the sub-pixel P unit along the row direction; n is the number of rows of the sub-pixel P.

Preferably, Δ x is h/| tan θ |, as shown in fig. 4, so that all thesignal lines 40 are located in thedisplay area 10, and the width of the frame is reduced to the maximum extent.

Next, optionally, thethird side 13 and thefourth side 14 are both oblique lines, and the side length of thefirst side 11 is smaller than that of thesecond side 12. For example, fig. 5 is a schematic structural diagram of another display panel provided in an embodiment of the present invention.

When the length of thefirst side 11 is smaller than that of thesecond side 12, optionally, the shape of the sub-pixel P is a rectangle; the value range of Δ x is:

wherein h is the height of the subpixel P in the column direction; theta is the angle between thethird side 13 and the first side 11 (or theta is the angle between thefourth side 14 and thefirst side 11; W is the width of the portion of thenon-display area 20 connected to thethird side 13; W is the pitch betweenadjacent signal lines 40 in the non-display area, the pitch including the line width and line pitch of the signal lines 40; d is the width of the sub-pixel P unit in the row direction; N is the number of rows of the sub-pixels P; and N is the difference between the row with the largest number of sub-pixels P and the row with the smallest number of sub-pixels P.

Specifically, the length of thefirst edge 11 is smaller than the length of thesecond edge 12, and the number of sub-pixels P in one row of sub-pixels P closest to the upper frame in the multiple rows of sub-pixels P is the largest, and even if Δ x ═ h/| tan θ |, the left frame area or the right frame area of the display panel needs to reserve the trace space for n signal lines 40, for example, in fig. 5, when Δ x ═ h/| tan θ | (θ is shown in fig. 5 as an included angle between thethird edge 13 and the first edge 11), the right frame needs to reserve the trace space for onesignal line 40. W/W-n indicates the number ofsignal lines 40 that can be provided, except for the trace space reserved for n signal lines 40, in the left frame or the right frame.

About

Can refer to the above for understanding

The explanation of (1) will not be repeated herein.

Preferably, Δ x is h/| tan θ |, as shown in fig. 5, which is advantageous in that the number ofsignal lines 40 can be minimized, thereby minimizing the width of the right frame.

Based on the above technical solution, with continuing reference to fig. 2, 4 and 5, optionally, thesignal line 40 includes acolumn line segment 41 and arow line segment 42 alternately connected to make thesignal line 40 in a step shape, where therow line segment 42 is parallel to thefirst side 11, and thecolumn line segment 41 is perpendicular to thefirst side 11.

The advantage of this arrangement is that the vertical projection of thesignal line 40 on the plane of the sub-pixel P is located outside the sub-pixel P, and thesignal line 40 does not block the light emitted from the sub-pixel P, which is beneficial to improving the display effect of the display panel. It should be noted that, when there is an overlap between the vertical projections of theline segments 42 of the twoadjacent signal lines 40 on the plane where the sub-pixels P are located, the twoadjacent signal lines 40 can be prevented from being short-circuited by arranging theline segments 42 of the twoadjacent signal lines 40 at different layers.

With reference to fig. 3, optionally, thesignal line 40 includes a column-direction line segment 41 and aslant line segment 43 alternately connected to make thesignal line 40 "step-like", wherein theslant line segment 43 has a predetermined included angle with thefirst side 11, the column-direction line segment 41 is perpendicular to thefirst side 11, and a perpendicular projection of theslant line segment 43 on a plane where the sub-pixel P is located at least partially within the sub-pixel P.

The advantage of this arrangement is that the vertical projections of twoadjacent signal lines 40 on the plane of the sub-pixel P can be prevented from overlapping, and the arrangement of thecolumn line segment 41 can reduce the occupation ratio of the portion of thesignal line 40 located in the sub-pixel P in the vertical projection on the plane of the sub-pixel P, thereby reducing the blocking of the sub-pixel P by thesignal line 40.

Fig. 6 is a schematic structural diagram of a display panel according to an embodiment of the present invention. Fig. 7 is a schematic structural diagram of another display panel according to an embodiment of the present invention. Optionally, thesignal line 40 includes a plurality ofarc segments 44 as shown in fig. 6, or a plurality ofinclined segments 43 as shown in fig. 7, and the vertical projection of thesignal line 40 on the plane of the sub-pixel P is located in the sub-pixel P.

This arrangement has the advantages of preventing the vertical projections of twoadjacent signal lines 40 on the plane of the sub-pixel P from overlapping, and is beneficial to reduce the total length of the signal lines 40, thereby reducing the loss of the signals transmitted on the signal lines 40.

It should be noted that fig. 6 only illustrates that, in thesame signal line 40, the curvatures of thearc line segments 44 are the same, but the present application is not limited thereto, and for example, in other embodiments, the curvatures of thearc line segments 44 may not be completely the same. Similarly, fig. 7 only illustrates that, in thesame signal line 40, the slopes of theinclined line segments 43 are the same, but the present application is not limited thereto, for example, in other embodiments, the slopes of theinclined line segments 43 may not be completely the same.

Fig. 8 is a schematic structural diagram of another display panel according to an embodiment of the present invention. Fig. 9 is a schematic structural diagram of another display panel according to an embodiment of the present invention. Referring to fig. 8 and 9, alternatively, the sub-pixels P are shaped as parallelograms; Δ x ═ h/| tan θ |; wherein h is the length of the sub-pixel P in the column direction, and the column direction is parallel to the row direction; theta is the angle between thethird side 13 and thefirst side 11.

For example, fig. 10 is a schematic structural diagram of a display panel according to an embodiment of the present invention. It is understood that when the slopes of thethird side 13 and thefourth side 14 are different, the sum of the included angle between thethird side 13 and thefirst side 11 and the included angle between thefourth side 14 and thefirst side 11 is not equal to 180 °, and in this case, the shape of the sub-pixel P may also be set to be a parallelogram; Δ x ═ h/| tan θ |; wherein h is the length of the sub-pixel P in the column direction, and the column direction is parallel to the row direction; θ is the angle between thefourth side 14 and thefirst side 11.

It can be understood that, the sub-pixels are arranged in a parallelogram shape, so that the vertical projection of thesignal line 40 on the plane where the sub-pixel P is located outside the sub-pixel P, and thesignal line 40 does not block the light emitted by the sub-pixel P, which is beneficial to improving the display effect of the display panel. It is also advantageous to reduce the overall length of thesignal line 40, thereby reducing the loss of the signal transmitted on thesignal line 40. In addition, when thedisplay region 10 is a parallelogram, thedisplay region 10 can be just filled with a plurality of rows of parallelogram-shaped sub-pixels P by flexibly adjusting the width of the parallelogram-shaped sub-pixels in the row direction.

In fig. 8, thethird side 13 is parallel to thefourth side 14, and the number of sub-pixels P in each row of sub-pixels P is the same, so that the number ofsignal lines 40 is equal to the number of sub-pixels P in each row of sub-pixels P, and eachsignal line 40 is located in the display area; in fig. 9, the slope of thethird side 13 is different from the slope of thefourth side 14, and the length of thefirst side 11 is smaller than the length of thesecond side 12, so that the number of sub-pixels P in the row of sub-pixels P closest to thefirst side 11 is smaller than the number of sub-pixels P in the row of sub-pixels P closest to thesecond side 12, when each sub-pixel P in the row of sub-pixels P closest to thefirst side 11 is connected to a corresponding signal line 40 (for example, after the sub-pixels P marked 1, 2, 3 · 29 are all connected to thesignal line 40 in fig. 9), a part of sub-pixels P (for example, the sub-pixels P marked 30 in fig. 9) in the row of sub-pixels P closest to thesecond side 12 are not connected to thesignal line 40, and thesignal line 40 connected to the part of sub-pixels P needs to be routed to the left frame or the right frame; in fig. 10, the slope of thethird side 13 is different from the slope of thefourth side 14, and the length of thefirst side 11 is greater than the length of thesecond side 12, so that the number of sub-pixels P in the row of sub-pixels P closest to thefirst side 11 is greater than the number of sub-pixels P in the row of sub-pixels P closest to thesecond side 12, and after each sub-pixel P in the row of sub-pixels P closest to thesecond side 12 is connected to a corresponding signal line 40 (for example, after all the sub-pixels P labeled 3, 4, 5 · 30 are connected to thesignal line 40 in fig. 10), a part of the sub-pixels P (for example, the sub-pixels P labeled 1, 2 in fig. 10) in the row of sub-pixels P closest to thefirst side 11 is not connected to thesignal line 40, and thesignal line 40 connected to the part of the sub-pixels P can still be in the display area without being routed on the left frame or the right frame. In summary, when the length of thefirst side 11 is greater than or equal to the length of thesecond side 12, all thesignal lines 40 can be routed in thedisplay area 10, and when the length of thefirst side 11 is less than the length of thesecond side 12, a part of thesignal lines 40 need to be routed in the left frame or the right frame.

Fig. 11 is a schematic structural diagram of another display panel according to an embodiment of the present invention. Fig. 12 is a schematic structural diagram of another display panel according to an embodiment of the present invention. Fig. 13 is a schematic structural diagram of a display panel according to an embodiment of the present invention. Referring to fig. 11 to 13, alternatively, the contour line of the subpixel P includes oppositely disposed fifth and sixth sides, and oppositely disposed seventh and eighth sides; the fifth side is parallel to the sixth side; the seventh side is respectively connected with the fifth side and the sixth side; the eighth side is respectively connected with the fifth side and the sixth side; the seventh side and the eighth side are both arcs, and the seventh side is parallel to the eighth side (the sub-pixel P with the characteristics is called an arc-shaped sub-pixel P); thesignal line 40 includes a plurality ofarc segments 44, and the concave direction of thearc segments 44 is the same as the concave direction of the seventh side.

Wherein the fifth side and the sixth side have the same side length. In two adjacent sub-pixels P connected to the same data line, the vertical projection of the fifth side of one sub-pixel P and the sixth side of the other sub-pixel P on thesecond side 12 of thedisplay area 10 coincide, that is, in the same sub-pixel P, the staggered distance of the fifth side and the sixth side in the row direction is the staggered distance Δ x of the two adjacent rows of sub-pixels P. In other words, when the distance Δ x by which the two adjacent rows of the sub-pixels P are staggered varies, the shape of the arc-shaped sub-pixels P needs to be changed accordingly.

The advantage of this arrangement is that the vertical projection of thesignal line 40 on the plane of the sub-pixel P is located outside the sub-pixel P, and thesignal line 40 does not block the light emitted from the sub-pixel P, which is beneficial to improving the display effect of the display panel. It is also advantageous to reduce the overall length of thesignal line 40, thereby reducing the loss of the signal transmitted on thesignal line 40.

It is understood that, when the sub-pixels P are arc sub-pixels P, the slope of the parallelogram or thethird side 13 of thedisplay area 10 is different from the slope of thefourth side 14, and the side length of thefirst side 11 is less than that of thesecond side 12, the offset distance Δ x (i.e. the offset distance of the fifth side and the sixth side in the row direction) of the sub-pixels P in two adjacent rows may be:

wherein h is the height of the subpixel P in the column direction; theta is the included angle between thethird side 13 and the first side 11 (or theta is the included angle between thefourth side 14 and the first side 11); w is the width of the portion of thenon-display area 20 connected to thethird side 13; w is a pitch betweenadjacent signal lines 40 in the non-display region, the pitch including a line width and a line distance of the signal lines 40; d is the width of the sub-pixel P unit along the row direction; n is the number of rows of the sub-pixel P.

When the sub-pixel P is an arc sub-pixel P, the slope of thedisplay area 10 is a parallelogram or the slope of thethird side 13 is different from the slope of thefourth side 14, and the side length of thefirst side 11 is longer than that of thesecond side 12, the range of the staggered distance Δ x (that is, the staggered distance of the fifth side and the sixth side in the row direction) of the sub-pixels P in two adjacent rows may be:

wherein h is the height of the subpixel P in the column direction; θ is the angle between thethird side 13 and the first side 11 (or the angle between thefourth side 14 and the first side 11); w is the width of the portion of thenon-display area 20 connected to thethird side 13; w is a pitch betweenadjacent signal lines 40 in the non-display region, the pitch including a line width and a line distance of the signal lines 40; d is the width of the sub-pixel P unit along the row direction; n is the number of rows of the sub-pixel P; n is the difference between the number of subpixels P in the row with the largest number of subpixels P and the number of subpixels P in the row with the smallest number of subpixels P.

It should be noted that, for understanding the value range of the staggered distance Δ x between two adjacent rows of the sub-pixels P when the sub-pixel P is the arc-shaped sub-pixel P, reference may be made to the foregoing, and details are not described herein again.

Preferably, Δ x ═ h/| tan θ |, as shown in fig. 11. This has the advantage of minimizing the number ofsignal lines 40 and thus the width of the bezel.

Alternatively, thedisplay area 10 includes a plurality of interconnected parallelograms arranged in a row direction.

For example, fig. 14 is a schematic structural diagram of another display panel provided in the embodiment of the present invention. Thedisplay area 10 may be divided into a plurality of parallel quadrilaterals in the row direction. Each parallel four-sub-polygon comprises a first sub-edge and a second sub-edge which are oppositely arranged, and a third sub-edge and a fourth sub-edge which are oppositely arranged; the first sub-edge is parallel to the second sub-edge; the third sub-edge is respectively connected with the first sub-edge and the second sub-edge; the fourth sub-edge is respectively connected with the first sub-edge and the second sub-edge; the included angle between the third sub-edge and the first sub-edge is an acute angle, and the included angle between the fourth sub-edge and the first sub-edge is an obtuse angle. The first sub-side of each parallelogram forms afirst side 11 of thedisplay area 10, the second sub-side of each parallelogram forms asecond side 12 of thedisplay area 10, the third sub-side of each parallelogram forms athird side 13 of thedisplay area 10 and the fourth sub-side of each parallelogram forms afourth side 14 of thedisplay area 10.

Specifically, when thedisplay region 10 includes a plurality of interconnected parallelograms, the sub-pixels P may be rectangular sub-pixels P, parallelogram-shaped sub-pixels P, or arc-shaped sub-pixels P, alternatively. Further, preferably, the sub-pixels P in two adjacent rows are staggered by a distance Δ x ═ h/| tan θ |; wherein h is the height of the subpixel P in the column direction; theta is an included angle between thethird side 13 and thefirst side 11; w is the width of the portion of thenon-display area 20 connected to thethird side 13; w is the width betweenadjacent signal lines 40 in the non-display region; d is the width of the sub-pixel P unit along the row direction; n is the number of rows of the sub-pixel P.

Optionally, thethird side 13 and thefourth side 14 are both arcs, and thethird side 13 is parallel to thefourth side 14.

Connecting lines of end points of thefirst side 11 and thesecond side 12 which are located on the same side are a third reference side and a fourth reference side respectively, and the third reference side is connected with thefirst side 11 and thesecond side 12 respectively; the fourth reference edge is connected to thefirst edge 11 and thesecond edge 12, respectively; the third reference edge forms an acute angle with thefirst edge 11, and the fourth reference edge forms an obtuse angle with thefirst edge 11.

Specifically, when thethird side 13 and thefourth side 14 of thedisplay area 10 are both arcs, the sub-pixel P may be a rectangular sub-pixel P or a parallelogram-shaped sub-pixel P. Further, preferably, the distance Δ x between two adjacent rows is h/| tan θ |; wherein h is the height of the subpixel P in the column direction; theta is the angle between thethird side 13 and thefirst side 11.

Fig. 15 is a schematic structural diagram of another display panel according to an embodiment of the present invention. When thethird side 13 and thefourth side 14 of thedisplay area 10 in thedisplay area 10 are both arcs, optionally, the sub-pixels P may also be arc-shaped sub-pixels P, and the fifth side of each arc-shaped sub-pixel P in each row of arc-shaped sub-pixels P is parallel to the portion of thethird side 13 of thedisplay area 10, which is directly opposite to the row of arc-shaped sub-pixels P. Thus, thesignal line 40 is parallel to thethird edge 13, that is, the vertical projection of thesignal line 40 on the plane of the sub-pixel P is located outside the sub-pixel P, and thesignal line 40 does not block the light emitted by the sub-pixel P, which is beneficial to improving the display effect of the display panel. It is also advantageous to reduce the overall length of thesignal line 40, thereby reducing the loss of the signal transmitted on thesignal line 40. In addition, the width of the sub-pixel P along the row direction can be properly set so that the sub-pixel P just fills thedisplay region 10.

Based on the above technical solution, optionally, thesignal line 40 includes a scan line or a data line.

Specifically, when the data lines are parallel to thefirst side 11 and the scan lines cross the data lines in the display panel, thesignal lines 40 may be scan lines; when the scan lines are parallel to thefirst side 11 and cross the data lines in the display panel, thesignal lines 40 can be data lines. The type of thesignal line 40 can be set by those skilled in the art according to practical situations, and is not limited herein.
