Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
As described in the background art, as the requirement for display accuracy of the display device increases, the application of the rendering technology becomes more and more extensive, and the rendering technology adopts lower process capability and achieves better display effect through the borrowing relationship between pixels. For example, in a display device adopting a rendering technology, each rendering pixel in the rendering pixel arrangement includes at least one sub-pixel, and colors of any two adjacent sub-pixels are different, but each pixel corresponding to an image input by the display device includes a red R sub-pixel, a green G sub-pixel, and a blue B sub-pixel, so that when the display device displays a picture, the rendering pixel needs to render by using the sub-pixels of the adjacent rendering pixels to achieve the purpose of displaying the image. However, when the edge rendering pixel of the rendering pixel arrangement borrows the adjacent rendering pixel, the sub-pixel of the adjacent rendering pixel cannot be borrowed by the edge rendering pixel completely, so that the edge rendering pixel of the rendering pixel arrangement has color cast due to insufficient borrowed brightness.
Based on this, the embodiment of the present application provides a display panel and a display device, where a compensation rendering pixel is disposed on an edge side of a pixel row, so that when the edge rendering pixel is driven, the edge rendering pixel borrows a sub-pixel of an adjacent rendering pixel, and meanwhile, the sub-pixel of the compensation rendering pixel can also be used to compensate for the situation of insufficient edge brightness, thereby improving the situation of color cast caused by insufficient borrowed brightness of the edge rendering pixel of the rendering pixel arrangement, and improving the display effect of the display device. In order to achieve the above object, the technical solutions provided in the embodiments of the present application are described in detail below, specifically with reference to fig. 1 to 4.
Referring to fig. 1, a schematic structural diagram of a rendering pixel arrangement provided in an embodiment of the present application is shown, where the embodiment of the present application provides a display panel, the display panel includes a rendering pixel arrangement 100, the rendering pixel arrangement includes a plurality of pixel rows and a plurality of pixel columns, each pixel row includes a first rendering pixel to an nth rendering pixel, each rendering pixel includes at least one sub-pixel, colors of any two adjacent sub-pixels are different, N is an integer not less than 3, and the display panel further includes:
at least one side of at least one of the pixel rows is provided with a compensation rendering pixel 100, wherein the number and color of the sub-pixels of the compensation rendering pixel 10 are the same as the number and color of the sub-pixels near the j-th rendering pixel 10j in the k-th rendering pixel 10k on the corresponding side (as shown in fig. 1, the sub-pixel near the j-th rendering pixel 10j of the k-th rendering pixel 10k is a sub-pixel X2, wherein the compensation rendering pixel 10 includes a sub-pixel X1 corresponding to the sub-pixel X2 of the k-th rendering pixel 10k and having the same color), j is 1 or N, k is 2 when j is 1, and k is N-1 when j is N.
It should be noted that the rendering pixel provided in the embodiment of the present application includes at least one sub-pixel, where the number of the sub-pixels of the rendering pixel is smaller than the number of the color types of the sub-pixels arranged in the rendering pixel, for example, if the color types of the sub-pixels arranged in the rendering pixel include three, the number of the sub-pixels included in the rendering pixel is one or two.
As can be seen from the above, in the technical solution provided in the embodiment of the present application, the compensation rendering pixel is disposed on the edge side of the pixel row, so that when the edge rendering pixel is driven, the sub-pixel of the adjacent rendering pixel is borrowed by the edge rendering pixel, and meanwhile, the sub-pixel of the compensation rendering pixel can also be used to compensate for the situation of insufficient edge brightness, thereby improving the situation of color cast caused by insufficient borrowed brightness of the edge rendering pixel of the rendering pixel arrangement, and improving the display effect of the display device.
It can be understood that, the jth rendering pixel provided in the embodiment of the present application is a rendering pixel at the edge of the rendering pixel arrangement, and the kth rendering pixel is a rendering pixel adjacent to the jth rendering pixel; wherein, when the j rendering pixel is driven to display, the j rendering pixel can borrow at least one sub-pixel in the adjacent k rendering pixel (at least one sub-pixel in the k rendering pixel is a sub-pixel of the corresponding color which is missed by the j rendering pixel, and at least one sub-pixel in the k rendering pixel is positioned at one side close to the j rendering pixel due to the different colors of the adjacent sub-pixels), meanwhile, the jth rendering pixel can also compensate the situation of insufficient edge brightness by using the sub-pixel in the corresponding compensation rendering pixel (the color and the quantity of the sub-pixel in the compensation rendering pixel are the same as those of the sub-pixel of the jth rendering pixel by using the kth rendering pixel), and further, the situation that the color cast is caused by insufficient borrowed brightness of the edge rendering pixels of the rendering pixel arrangement is improved, and the display effect of the display device is improved.
In an embodiment of the present application, the number and the position of the compensation rendering pixels may be designed according to a specific arrangement structure of the arrangement of the rendering pixels. Preferably, a compensation rendering pixel is disposed on both sides of each pixel row provided in the embodiment of the present application. That is, a first compensation rendering pixel and a second compensation rendering pixel are respectively arranged on two sides of any one of the pixel rows provided by the present application, the first compensation rendering pixel is located on one side of the first rendering pixel, and the number and color of the sub-pixels of the first compensation rendering pixel are both the same as the number and color of the sub-pixels of the second rendering pixel, which are close to one side of the first rendering pixel;
the second compensation rendering pixel is positioned on one side of the Nth rendering pixel, and the number and the color of the sub-pixels of the second compensation rendering pixel are correspondingly the same as those of the sub-pixels, close to the Nth rendering pixel, in the N-1 th pixel.
Further, a rendering pixel borrowing relationship of an edge provided by the embodiment of the present application is described in detail with reference to fig. 2a, and fig. 2a is a rendering pixel borrowing relationship schematic diagram provided by the embodiment of the present application, where in the embodiment of the present application, it is described that a rendering pixel arrangement includes subpixels of three colors, and a rendering pixel includes two subpixels, and the three color subpixels are a red R subpixel, a green G subpixel, and a blue B subpixel, respectively; the j-th rendering pixel 10j includes two sub-pixels sequentially arranged as a red R sub-pixel R1 and a green G sub-pixel G, the k-th rendering pixel 10k includes two sub-pixels sequentially arranged as a blue B sub-pixel B1 and a red R sub-pixel R2 in the same order, and the number and the color of the sub-pixels of the compensation rendering pixel 10 are the same as those of the sub-pixels of the k-th rendering pixel 10k near the j-th rendering pixel 10j, so that the sub-pixels of the compensation rendering pixel 10 are the blue B sub-pixel B2.
As shown in fig. 2a, when the jth pixel 10j is driven, the jth pixel 10j needs to borrow the adjacent blue sub-pixel because the jth pixel 10j only includes the red R sub-pixel R1 and the green G sub-pixel G; the jth rendering pixel 10j borrows the blue B sub-pixel B1 in the adjacent kth rendering pixel, and the blue B sub-pixel B1 needs to function as a blue sub-pixel in the kth rendering pixel and cannot be fully borrowed by the jth rendering pixel 10j, so that the situation that the edge of the rendering pixel arrangement is color-biased due to insufficient brightness of the borrowed blue B sub-pixel B1 occurs at this time; therefore, the jth rendering pixel 10j provided by the embodiment of the present application also needs to perform luminance compensation by using the blue B sub-pixel B2 in the compensation rendering pixel 10, and the portion with insufficient luminance by using the blue B sub-pixel B1 performs luminance compensation by using the blue B sub-pixel B2, so as to improve the color cast caused by insufficient luminance in the edge rendering pixels of the rendering pixel arrangement, and improve the display effect of the display device.
In an embodiment of the present application, the size of the area of the sub-pixel of the compensation rendering pixel is not specifically limited, where the area of the sub-pixel of the compensation rendering pixel provided by the present application is not greater than the area of the sub-pixel of the kth rendering pixel, which is close to the jth rendering pixel and has the same color.
The area of the sub-pixels of the rendering compensation pixels provided by the embodiment of the application can be set to be not larger than the area of the sub-pixels with the same color on the side close to the jth rendering pixel in the kth rendering pixel, wherein the compensation rendering pixels do not need to display a picture and only play a role of being borrowed by the jth rendering pixel, so that the sub-pixels of the rendering compensation pixels do not need to be designed to have a large area, and further on the premise of improving the display effect by being borrowed by the jth rendering pixel, the width of a frame area of a display device can be prevented from being increased, and the narrow frame development trend is met.
It can be understood that, if one of the sub-pixels of the kth rendering pixel, which is close to the jth rendering pixel, is a first predetermined sub-pixel, the compensation rendering pixel includes a second predetermined sub-pixel having the same color as the first predetermined sub-pixel, wherein the area of the second predetermined sub-pixel is not greater than the area of the first predetermined sub-pixel; or, if two sub-pixels arranged in the column extending direction of the sub-pixel on the side of the kth rendering pixel close to the jth rendering pixel are respectively a first preset sub-pixel and a second preset sub-pixel, the compensation rendering pixel comprises a third preset sub-pixel having the same color as the first preset sub-pixel and a fourth preset sub-pixel having the same color as the second preset sub-pixel, the arrangement sequence of the third preset sub-pixel and the fourth preset sub-pixel is the same as the arrangement sequence of the first preset sub-pixel and the second preset sub-pixel corresponding to the same color, and the area of the third preset sub-pixel is not larger than the area of the first preset sub-pixel, the area of the fourth preset sub-pixel is not larger than the area of the second preset sub-pixel, and so on the situation when the compensation rendering pixel comprises more sub-pixels.
Specifically, referring to fig. 2b, a schematic diagram of the area of a sub-pixel of a compensation pixel is shown, wherein one of the sub-pixels of the kth rendering pixel 10k near the jth rendering pixel 10j is a sub-pixel X2, and the compensation pixel 10 includes a sub-pixel X1 corresponding to the sub-pixel X2 of the kth rendering pixel 10k and having the same color; in an embodiment of the present application, the area of the sub-pixel X2 may be larger than the area of the sub-pixel X1.
It should be noted that the area of each sub-pixel of the rendering pixel arrangement provided in the embodiment of the present application may be the same size of sub-pixel, and in other embodiments, the area of each sub-pixel may also be different sizes of sub-pixels, which is not specific to the present application.
In an embodiment of the present application, when the jth rendering pixel is driven, the data voltage corresponding to the corresponding color is allocated according to a ratio of an area of the sub-pixel of the compensation rendering pixel to an area of the sub-pixel of the same color on a side, close to the jth rendering pixel, of the kth rendering pixel.
The area size of the sub-pixels of the compensation rendering pixel provided by the embodiment of the application is related to the proportion of the data voltage of the sub-pixels with the same color distributed to the kth rendering pixel to the total data voltage; that is, the ratio of the area of the sub-pixel of the compensation rendering pixel to the area of the sub-pixel of the same color in the kth rendering pixel affects the distribution of the total data voltage. For example, one of the sub-pixels of the kth rendering pixel, which is close to the jth rendering pixel, is a first preset sub-pixel, and the compensation rendering pixel includes a second preset sub-pixel having the same color as the first preset sub-pixel, at this time, the area of the second preset sub-pixel may be a borrowing coefficient multiplied by the area of the first preset sub-pixel, where the borrowing coefficient is a weight of a total data voltage corresponding to a color transmitted to the first preset sub-pixel in the rendering process.
It should be noted that, the area size of the sub-pixel of the compensation rendering pixel provided in the embodiment of the present application needs to be specifically designed according to each parameter of the display device in practical application, and the present application is not particularly limited. In addition, in the above "allocating the corresponding data voltage corresponding to the color according to the ratio of the area of the sub-pixel of the compensated rendering pixel to the area of the sub-pixel of the same color on the side of the kth rendering pixel close to the jth rendering pixel," the corresponding data voltage "is the data voltage required by the corresponding color sub-pixel for the jth rendering pixel, and therefore, the data voltage on the corresponding data line of the sub-pixel of the kth rendering pixel close to the jth rendering pixel corresponding to the compensated rendering pixel actually consists of two parts: the first is the data voltage required by the k-th rendering pixel when displaying, and the second is the data voltage distributed according to the distribution condition when being borrowed by the j-th rendering pixel.
In any of the above embodiments of the present application, the rendering pixel arrangement provided in the embodiments of the present application is a pixel arrangement structure capable of displaying an image through a rendering technology, the structure of the rendering pixel arrangement is not limited in the present application, and the present application needs to be designed according to practical applications, and the following further describes the technical scheme provided in the present application through two specific rendering pixel arrangement structures.
