In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure.

In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the disclosure.
Fig. 2 is a flowchart illustrating steps of a display method provided in an embodiment of the present disclosure, where the display method may be applied to a display panel driven by at least two data drivers, and the display panel may be an OLED display panel.
As shown in fig. 2, in step S10, at least two data drivers respectively provide data signals to at least two pixel arrays in the display panel, wherein each pixel array includes a plurality of pixel units. A narrow boundary exists between the pixel arrays, and the boundary is used as a boundary, and the pixel arrays between every two boundaries are driven by providing data signals through corresponding data drivers.
As shown in fig. 2, in step S20, each two adjacent data drivers respectively use the adjacent data drivers to render the data signals of the pixel units at the boundary.
In the present embodiment, two data drivers are taken as an example, that is, at least two data drivers include a first data driver and a second data driver, and the first data driver and the second data driver are respectively used for driving a first pixel array and a second pixel array that are adjacent to each other on a display screen. The first pixel array and the second pixel array each include M (columns) × N (rows) pixel units.
Taking a part of the first pixel array as an example, fig. 3 shows a schematic diagram of the pixel array. Each pixel unit includes a first sub-pixel S1, a second sub-pixel S2, and a third sub-pixel S3, and the three sub-pixels are arranged in a "pin" shape, as shown in fig. 3, the specific structure of the "pin" shape is: the first sub-pixel S1 and the second sub-pixel S2 are located in the same pixel column (e.g., a single column), and the third sub-pixel S3 is located in a pixel column (e.g., a double column) adjacent thereto. Meanwhile, the pixel columns of the first sub-pixel S1 and the second sub-pixel S2 and the pixel column of the third sub-pixel S3 on adjacent rows are staggered, so that sub-pixels of other colors are arranged around the sub-pixel of each color, thereby realizing more effective color rendering. In the present embodiment, the colors of the first sub-pixel S1, the second sub-pixel S2, and the third sub-pixel S3 may be red, green, and blue, respectively.
Still taking fig. 3 as an example, the data line D1 provides data signals for the first sub-pixel S1 of the first row and column (odd row and column) and the third sub-pixel S3 of the first row and column (even row and odd column), the data line D2 provides data signals for the second sub-pixel S2 of the first row and column (odd row and odd column) and the first sub-pixel S1 of the second row and column (even row and even column), and the data line D3 provides data signals for the third sub-pixel S3 of the first row and second column (odd row and even column) and the second sub-pixel S2 of the second row and second column (even row and even column). Similarly, the connection relationships between the data lines D4-D6 and the data lines D1-D3 and the sub-pixels are similar.
In this embodiment, the manner of rendering by using the data signals of the pixel units close to the edge in the pixel array driven by the adjacent data drivers may be:
the last pixel cell in the first pixel array along the first direction X1 is rendered by the data signals of the first Q pixel cells in the second pixel array along the first direction X1, and the first pixel cell in the second pixel array along the first direction X1 is rendered by the data signals of the first Q pixel cells in the first pixel array along the second direction X2, wherein Q is greater than or equal to 2, and the first direction X1 is opposite to the second direction X2.
Fig. 4 is a schematic diagram illustrating a correspondence relationship between two pixel arrays and a display screen, where the pixel arrays include 2M columns × N rows of pixel units, and the display screen 10 is divided into two parts, and corresponds to the two pixel arrays, which are respectively represented by a first pixel array 11 and a second pixel array 12. The pixel units in the H1 line frame are composed of two parts, one part is from the last pixel unit (i.e. the last group of RGB) of the first pixel array 11, the other part is from the first pixel unit (i.e. the first group of RGB) of the second pixel array 12, and each sub-pixel in the two parts of pixel units in the H1 line frame is rendered by the data signal of the sub-pixel of the corresponding color in the other pixel array, so as to compensate the thrust difference generated when the two data drivers drive the two pixel arrays independently.
Regarding the structure of each pixel array, taking the pixel unit shown in the frame of H2 in the first partial pixel array 11 as an example, the arrangement of the sub-pixels in odd columns is RGB, RGB … …, and the arrangement of the sub-pixels in even columns is BRG, BRG … …, and the sub-pixels in the same color in odd columns and even columns have a difference of at least 1.5 sub-pixel pitches, so as to realize rendering fusion of the sub-pixels and the adjacent sub-pixels in different colors in each pixel unit, and achieve better display effect. The specific rendering within the box H1 is as follows:
as shown in fig. 4, when data of one RGB pixel is externally input to the first row of pixel cells, 1/3 pixels are cut off after rendering through the pixel arrangement in the H2 wire frame, and only 2/3 pixels remain, so that one RGB pixel data is computed and rendered in V1 to obtain RG, and then computed and rendered in V2 to obtain BR. And performing operation and rendering in V3 to obtain GB. Although the arrangement of the sub-pixels in the second row of pixel units is staggered with the arrangement of the sub-pixels in the first row, the rendering manner is the same, and is not described herein.
In this embodiment, taking the case of Q being 2 as an example, that is, rendering is performed by using the data signals of two pixel units in adjacent pixel arrays, the formula for rendering by using the data signals of the first two pixel units in the first direction X1 in the second pixel array 12 by the last pixel unit in the first direction X1 in the first pixel array 11 is as follows:
(SM-2)’＝α*(SM-2)+β*(S1)+γ*(S4)
(SM-1)’＝α*(SM-1)+β*(S2)+γ*(S5)
(SM)’＝α*(SM)+β*(S3)+γ*(S6)
with reference to fig. 4, where (SM-2) ' is the luminance value of the first sub-pixel in the last pixel unit along the first direction X1 in the first pixel array 11 after rendering, (SM-1) ' is the luminance value of the second sub-pixel in the last pixel unit along the first direction X1 in the first pixel array 11 after rendering, (SM) ' is the luminance value of the first sub-pixel in the last pixel unit along the first direction X1 in the first pixel array 11 after rendering, (SM-2) is the luminance value of the first sub-pixel in the last pixel unit along the first direction X1 in the first pixel array 11 before rendering, (SM-1) is the luminance value of the second sub-pixel in the last pixel unit along the first direction X1 in the first pixel array 11 before rendering, (SM) is the luminance value of the third sub-pixel in the last pixel unit along the first direction X1 in the first pixel array 11 before rendering, (S3) is the luminance value of the third sub-pixel in the last pixel unit along the first direction X6325 in the first pixel array 11 before rendering, (S-2) is the luminance value of the second sub-pixel array S9642 in the first pixel array before rendering, (S-7) is the luminance value of the second sub-pixel array S3642 in the first pixel array before rendering, (S-X9612) is the second sub-pixel array S3 in the first pixel array before rendering, (S3) is the second sub-pixel array S3 in the second sub-pixel array S3612 in the second pixel array before rendering direction X3612, and the second sub-.
Similarly, when Q is 2, the first pixel cell in the second pixel array 12 along the first direction X1 uses the data signals of the first Q pixel cells in the first pixel array 11 along the second direction X2 to perform rendering according to the following formula:
(S1)’＝α*(S1)+β*(SM-2)+γ*(SM-5)
(S2)’＝α*(S2)+β*(SM-1)+γ*(SM-4)
(S3)’＝α*(S3)+β*(SM)+γ*(SM-3)
where (S1) ' is the luminance value of the first sub-pixel in the first pixel unit along the first direction X1 in the second pixel array 12 after rendering, (S2) ' is the luminance value of the second sub-pixel in the first pixel unit along the first direction X1 in the second pixel array 12 after rendering, (S3) ' is the luminance value of the first sub-pixel in the first pixel unit along the first direction X1 in the second pixel array 12 after rendering, (S1) is the luminance value of the first sub-pixel in the first pixel unit along the first direction X1 in the second pixel array 12 before rendering, (S2) is the luminance value of the second sub-pixel in the first pixel unit along the first direction X1 in the second pixel array 12 before rendering, (S3) is the luminance value of the third sub-pixel in the first pixel unit along the first direction X1 in the second pixel array 12 before rendering, (S SM-2-SM 5) is the luminance value of the third sub-pixel in the first pixel unit along the first direction X1 in the second pixel array before rendering, (S SM-11) is the luminance value of the first sub-pixel array before rendering, (S3611) is the luminance value of the second pixel array X11 in the first pixel array before rendering, (S X9611, and (S3611) is the luminance value of the first sub-M-3 in the first pixel array before rendering, (S3611, the second pixel array before rendering direction X11, and the luminance value of the second pixel array before rendering, (S3611) is the second pixel array before rendering coefficients of the second pixel array before rendering, (S3611, respectively, and the luminance value of the second pixel array before rendering coefficients of the first pixel array before rendering, (S3611).
Each sub-pixel in the first column of pixel units in the second pixel array, namely the pixel units formed by S1, S2 and S3, is rendered by the data signals of the corresponding color sub-pixel in the first 2 columns of pixel units (namely the pixel units formed by S1, S2 and S3 and the pixel units formed by S4, S5 and S6) in the first pixel array (namely the pixel units formed by SM-2, SM-1 and SM).
Rendering is performed according to the above manner, and the obtained display effect on the display screen is as shown in fig. 5, so that bright lines can be avoided from appearing in the middle, and the display effect is improved.
In summary, the display method provided by this embodiment can solve the problem that in the prior art, two data drivers independently provide data signals, and a bright line appears in the middle of a display screen due to a thrust difference, which affects the display effect.

The rendering module 120 is configured to render the data signals of the pixel units at the boundary by using the adjacent data drivers respectively for every two adjacent data drivers.
The at least two data drivers for driving the display panel in this embodiment take two data drivers as an example, and include a first data driver and a second data driver, where the first data driver and the second data driver are respectively used for driving a first pixel array and a second pixel array adjacent to each other on the display panel, as shown in fig. 4.
As shown in fig. 6, in the present embodiment, the rendering module 120 includes: a first rendering sub-module 121 and a second rendering sub-module 122. The first rendering submodule 121 is configured to render, by using the data signals of the first Q pixel units in the first direction in the second pixel array, the last pixel unit in the first pixel array in the first direction; the second rendering submodule 122 is configured to render a first pixel unit in the second pixel array along the first direction by using the data signals of the first Q pixel units in the first pixel array along the second direction; wherein Q is greater than or equal to 2, and the first direction is opposite to the second direction.
