These terms are only used to distinguish the light-emitting color sub-pixels from each other. For example, the first light-exiting color sub-pixel may also be referred to as a second light-exiting color sub-pixel, and similarly, the second light-exiting color sub-pixel may also be referred to as a first light-exiting color sub-pixel without departing from the scope of the embodiments of the present invention.

In addition, in this context, it is also to be understood that when an element is referred to as being "on" or "under" another element, it can be directly formed on "or" under "the other element or be indirectly formed on" or "under" the other element through an intermediate element.
Before explaining the technical scheme of the embodiment in detail, the special-shaped display area and the technical problems related to the embodiment are briefly introduced:
generally, the display area of the display panel is designed to be rectangular, and most of mobile phones are rectangular in shape, for example. With the rise of wearable devices, the personalized requirements of users are met, and the shapes of display panels are more and more diversified, such as circular, fan-shaped, arc-shaped, groove-shaped and the like. In this embodiment, a region surrounded by a region in which the pixel units are not rectangular is referred to as an irregular display region, that is, only the pixel units in which the pixel units are not rectangular are included in the irregular display region. However, this is not to be understood as the special-shaped display area is only involved in the present embodiment, and the display area in the present embodiment may also include a normal display area, or may include a normal display area except for the special-shaped display area.
Illustratively, as shown in fig. 1, which is a schematic structural diagram of a display panel in the prior art, a display panel 100 ' includes an irregular pixel unit 102 ' and a regular pixel unit 101 '. Each shaped pixel cell 102 'includes a first edge line 104' adjacent the shaped edge, the first edge line 104 'extending along the shaped edge 103'.
As shown in fig. 1, for the sub-pixels with the same light-emitting color, the proportion of the area of the sub-pixels with the light-emitting color in the special-shaped pixel unit is different from the proportion of the area of the sub-pixels with the light-emitting color in the conventional pixel unit, so that the current densities of the two sub-pixels are different and the luminance per unit area is different when the turn-on voltages are the same, and during macroscopic display, because the opening area of the sub-pixels in the special-shaped pixel unit is smaller and the luminance per unit area is larger, an edge bright spot is easily formed, and the display quality is affected.
Moreover, for the special-shaped pixel unit, the opening area of the sub-pixels included in the special-shaped pixel unit is different from the opening area of the sub-pixels with the same color in the conventional pixel unit, so that the opening area of the whole special-shaped pixel unit is different from the opening area of the conventional pixel unit, and further, when white light is formed after all the sub-pixels included in one pixel unit are lightened, the luminance decay speed of the special-shaped pixel unit is slow, and the pixel white balance at the edge of the display panel is shifted to the conventional display area after a period of time, so that the display quality is influenced.
In addition, due to the limitation of the special-shaped edge, the opening area of each sub-pixel included in the special-shaped pixel unit adjacent to the special-shaped edge is different, and when white light is formed, the color of the white light is different from that of the white light formed by a conventional sub-pixel, so that color deviation at the special-shaped edge is caused. In order to improve color shift, the opening area of the sub-pixel included in the special-shaped pixel unit can be set to be consistent, and certainly, the opening area of the sub-pixel is kept consistent with the sub-pixel with the smallest opening area, that is, the special-shaped sub-pixel unit can sacrifice the opening area to improve the color shift, but at this time, the light transmission effect of the special-shaped pixel unit is poor because the opening area of the special-shaped pixel unit is further reduced.
If the irregular display area is not provided with the irregular pixel units, the display panel will have sawteeth on the edge thereof, which will also affect the display quality.
In order to solve the above problems and provide display quality, the inventors have devised the following technical solutions:
in the present embodiment, as shown in fig. 2, which is a schematic structural diagram of a display panel provided in the embodiment of the present invention, a display panel 100 includes N sub-pixels with different light emitting colors, where N is a positive integer and N is greater than or equal to 3. As shown in fig. 2, the display panel 100 may include a first light-emitting color sub-pixel 101, a second light-emitting color sub-pixel 102, and a third light-emitting color sub-pixel 103.
Continuing with fig. 2, the display panel 100 includes a display area 1 and a non-display area 2 surrounding the display area 1, the display area 1 includes a regular display area 11 and at least one shaped display area 12, the shaped display area 12 is located at an edge of the display area 1, and the shaped display area 12 includes a shaped edge 121.
The irregular display area 12 includes at least one irregular pixel unit 20, the irregular pixel unit 20 includes N sub-pixels with different light-emitting colors, and the irregular pixel unit 20 may include a first light-emitting color sub-pixel 101, a second light-emitting color sub-pixel 102, and a third light-emitting color sub-pixel 103. The sub-pixel adjacent to the shaped edge 121 in the shaped pixel unit 20 comprises a first edge 21, and the first edge 21 of at least one sub-pixel in the shaped pixel unit 20 extends along the shaped edge 121 adjacent thereto. It can be understood that the first edge 21 of the sub-pixel included in the odd-shaped pixel unit 20 adjacent to the odd-shaped edge 121 has the same shape as the odd-shaped edge 121, which facilitates to dispose the sub-pixel at the edge of the display area 11, thereby avoiding the formation of jaggies therein and improving the display effect of the edge of the display panel.
With continued reference to fig. 2, the regular display area 11 includes at least one regular pixel unit 10, the regular pixel unit 10 includes N sub-pixels with different light-emitting colors, and for example, the regular pixel unit 10 may include a first light-emitting color sub-pixel 101, a second light-emitting color sub-pixel 102, and a third light-emitting color sub-pixel 103.
Wherein, the area of the sub-pixel with any one of the light colors in the normal pixel unit 10 occupying the normal pixel unit 10 is P1, the area of the sub-pixel with the same light color in the special-shaped pixel unit occupying the special-shaped pixel unit is P2, and the following conditions are satisfied between P1 and P2: the absolute value of P1-P2 is more than or equal to 0 percent and less than or equal to 10 percent.
It is understood that the area of the pixel unit (the irregular pixel unit and the regular pixel unit) can be understood as the opening area thereof, the area of the sub-pixel included in the pixel unit can be understood as the opening area of the sub-pixel, and the opening area of the pixel unit is the sum of the opening areas of all the sub-pixels included in the pixel unit. Taking the first light-emitting color sub-pixel 101 as an example, the aperture area of the first light-emitting color sub-pixel in the special-shaped pixel unit 20 is P2, the aperture area of the first light-emitting color sub-pixel in the conventional pixel unit 10 is P1, and the difference between the two is within 10%, which can be understood as being similar or even the same.
In this embodiment, for the sub-pixels with the same color of emitted light, the proportion of the sub-pixels occupying the opening area of the special-shaped pixel unit is similar to or even the same as that of the sub-pixels occupying the opening area of the conventional pixel unit, and the brightness of the single-side area is similar to or even the same as that of the sub-pixels, so that the edge bright spot phenomenon is improved, and the display quality is improved.
And all the sub-pixels included in the pixel unit form white light after being lightened, at the moment, the opening area of the sub-pixel with any light-emitting color in the special-shaped pixel unit accounts for the proportion of the special-shaped pixel unit, and the proportion of the opening area of the sub-pixel with the same light-emitting color accounts for the same proportion of the special-shaped pixel unit and the conventional pixel unit, so that the attenuation speed of the white brightness formed by the special-shaped pixel unit is similar to or even the same as the attenuation speed of the white brightness formed by.
In addition, the ratio of the opening areas of the three sub-pixels with different light emitting colors in the special-shaped pixel unit is close to or even equal to the ratio of the opening areas of the three sub-pixels with different colors in the conventional pixel unit, and the formed white light colors are close to or even equal to each other, so that the color cast problem at the special-shaped edge can be obviously improved, and meanwhile, the opening area of the special-shaped pixel unit at the special-shaped edge is not reduced, so that the light transmission amount at the special-shaped edge is not reduced.
In one embodiment, the first edge of each sub-pixel in the odd-shaped pixel unit 20 extends along the odd-shaped edge 121 adjacent thereto. As shown in fig. 2, the first edge of the first emergent color sub-pixel 101, the first edge of the second emergent color sub-pixel 102, and the first edge of the third emergent color sub-pixel 103 included in the heteromorphic pixel unit 20 are adjacent to the heteromorphic edge 121 and have the same extending direction.
For the special-shaped edge only has one or both sub-pixels of light-emitting color and causes the condition of various limit, this embodiment is provided with the sub-pixel of three kinds of different light-emitting colors along the extending direction of special-shaped edge 121 for each sub-pixel evenly distributed has avoided the appearance of various limit at the edge of display area, has improved the various limit problem in edge, has improved display effect.
In one embodiment, the modified pixel unit 20 includes a blue sub-pixel having a blue color, and a first edge of the blue sub-pixel extends along a modified edge adjacent to the first edge. As shown in fig. 3, which is another schematic structural diagram of the display panel according to the embodiment of the present invention, in the three sub-pixels with different light-emitting colors included in the irregular pixel unit 20, for example, the first light-emitting color sub-pixel 101 is a blue sub-pixel.
In this embodiment, since the luminance of the blue sub-pixel is smaller than that of the red sub-pixel and the green sub-pixel, a gradual change of luminance is formed in the direction from the non-display area 2 to the display area 1, as shown by the arrow in fig. 3, so as to avoid the phenomenon of edge bright ring caused by the abrupt change of luminance from the display area to the non-display area.
In one embodiment, as shown in fig. 2 and 3, the heteromorphic pixel cell 20 includes a first light-emitting color sub-pixel 101, a second light-emitting color sub-pixel 102, and a third light-emitting color sub-pixel 103, wherein the first light-emitting color sub-pixel 101, the second light-emitting color sub-pixel 102, and the third light-emitting color sub-pixel 103 are arranged in a delta shape in the heteromorphic pixel cell 20.
In combination with the above embodiments, the first light-emitting color sub-pixel 101, the second light-emitting color sub-pixel 102, and the third light-emitting color sub-pixel 103 are arranged in a delta shape, so that the aperture area of the three different light-emitting color sub-pixels can be reasonably allocated, and the aperture area specific weights of the three different light-emitting color sub-pixels in the conventional pixel unit are similar to or even the same as those of the three different light-emitting color sub-pixels in the conventional pixel unit, thereby avoiding the occurrence of edge bright spots and color cast and improving the display quality.
On the basis of the above embodiments, the present embodiment exemplarily presents the following arrangements:
first, as shown in fig. 2, the first light-emitting color sub-pixel 101 and the second light-emitting color sub-pixel 102 are located in the same row, and the first edge of the first light-emitting color sub-pixel 101, the first edge of the second light-emitting color sub-pixel 102, and the first edge of the third light-emitting color sub-pixel 103 all extend along the irregular edge 121 adjacent thereto. It is understood that all the sub-pixels included in the shaped pixel unit 20 in the present embodiment are adjacent to and extend along the shaped edge. In this embodiment, the sub-pixels with three different light-emitting colors are arranged along the extending direction of the special-shaped edge 121, so that the sub-pixels with three different light-emitting colors are uniformly distributed at the edge of the display area, thereby avoiding the occurrence of a colored edge, improving the problem of the colored edge at the edge, and improving the display effect.
Second, as shown in fig. 4, which is another structural schematic diagram of the display panel provided in the embodiment of the present invention, the first light-emitting color sub-pixel 101 and the second light-emitting color sub-pixel 102 are located in the same column, and a first edge of the first light-emitting color sub-pixel 101 and a first edge of the third light-emitting color sub-pixel 103 both extend along the adjacent special-shaped edge 121. It will be appreciated that the second exit color sub-pixel 102 is not adjacent to the profiled edge 121, only the first exit color sub-pixel 101 and the third exit color sub-pixel 103 are adjacent to the profiled edge 121 and extend along the profiled edge 121.
In this embodiment, the arrangement method facilitates area distribution of three different light-emitting color sub-pixels in the special-shaped pixel unit with a limited area, so that the area proportion of each light-emitting color sub-pixel in the special-shaped pixel unit is similar to or even the same as the proportion of the same light-emitting color sub-pixel in the conventional pixel unit, thereby improving color cast and bright spots at the special-shaped edge and improving display quality.
Further, on the basis of the second illustrated pixel arrangement, the first light-emitting color sub-pixel 101 and the second light-emitting color sub-pixel 102 are each one of a red sub-pixel and a green sub-pixel, and the third light-emitting color sub-pixel is a blue sub-pixel.
Because the brightness of the blue sub-pixel is smaller than the brightness of the red sub-pixel and the green sub-pixel, the blue sub-pixel is arranged on one side of the special-shaped pixel unit close to the special-shaped edge, so that the brightness is gradually transited in the direction from the non-display area to the display area, and the phenomenon of edge bright circles is improved.
Third, as shown in fig. 5, which is another structural schematic diagram of the display panel provided in the embodiment of the present invention, the first light-emitting color sub-pixel 101 and the second light-emitting color sub-pixel 102 are located in the same row, and a first edge of the first light-emitting color sub-pixel 101 and a first edge of the third light-emitting color sub-pixel 103 both extend along the adjacent special-shaped edge 121. It will be appreciated that the first light-exit color sub-pixel 101 and the third light-exit color sub-pixel 103 are arranged along a profiled edge and the second light-exit color sub-pixel 102 is not adjacent to the profiled edge 121.
In this embodiment, the arrangement method facilitates area distribution of three different light-emitting color sub-pixels in the special-shaped pixel unit with a limited area, so that the area proportion of each light-emitting color sub-pixel in the special-shaped pixel unit is similar to or even the same as the proportion of the same light-emitting color sub-pixel in the conventional pixel unit, thereby improving color cast and bright spots at the special-shaped edge and improving display quality.
Fourth, as shown in fig. 6, which is another structural schematic diagram of the display panel provided in the embodiment of the present invention, the first light-emitting color sub-pixel 101 and the second light-emitting color sub-pixel 102 are located in the same row, and the first edge of the first light-emitting color sub-pixel 101, the first edge of the second light-emitting color sub-pixel 102, and the first edge of the third light-emitting color sub-pixel 103 all extend along the adjacent odd-shaped edge 121.
In this embodiment, the arrangement method facilitates area distribution of three different light-emitting color sub-pixels in the special-shaped pixel unit with a limited area, so that the area proportion of each light-emitting color sub-pixel in the special-shaped pixel unit is similar to or even the same as the proportion of the same light-emitting color sub-pixel in the conventional pixel unit, thereby improving color cast and bright spots at the special-shaped edge and improving display quality.
The special-shaped pixel unit extends along the row direction, occupies the positions of four sub-pixels in the column direction, and is limited by the special-shaped edge, so that the area occupied by the outermost sub-pixel is too small to be enough to arrange one sub-pixel.
In this embodiment, as shown in fig. 7, it is another structural schematic diagram of the display panel provided in the embodiment of the present invention, it can be seen that the position is merged into the irregular pixel units adjacent to each other in the column direction, so as to compensate the missing opening area of the irregular pixel unit 20 due to the irregular edge, thereby on one hand, increasing the opening area of the irregular pixel unit, and on the other hand, satisfying the proportion of the sub-pixels with any light-emitting color in the irregular pixel unit, which is similar to or even the same as the proportion of the sub-pixels with the same light-emitting color in the conventional pixel unit, improving the problem of edge bright spots, and improving the display quality.
