step S110, obtaining source image data, wherein the source image data comprises gray scale data of a plurality of image pixels;
step S120, determining a rendering mode corresponding to the source image data according to the source image data as a target rendering mode, wherein the rendering mode at least comprises a first rendering mode and a second rendering mode;

in the first rendering mode, any one screen pixel and an adjacent screen pixel share one sub-pixel;

According to the driving method of the embodiment of the disclosure, a target rendering mode can be selected from multiple rendering modes according to the acquired source image data, data conversion is performed according to the target rendering mode, and gray scale data of image pixels are converted into gray scale data displayed by each sub-pixel of a display panel, so that a plurality of screen pixels are generated on the display panel to display an image. In this process, the sub-pixels can be shared in different ways by different rendering modes, so that an image is displayed with higher resolution without changing the number of sub-pixels of the display panel. Wherein:
in the first rendering mode, any screen pixel and an adjacent screen pixel share one sub-pixel, and can be used for displaying an image with high requirements on color cast and low requirements on jaggy feeling. In the second rendering mode, any screen pixel and an adjacent screen pixel share one sub-pixel and can be used for displaying an image with low requirements on color cast. In the second rendering mode, any screen pixel and a plurality of adjacent screen pixels share one sub-pixel, so that the resolution can be improved, and the method can be used for displaying images with high sawtooth feeling requirements and low color cast requirements. Thus, an appropriate rendering mode may be determined from the source image data in order to improve the display effect.
The following describes each step of the driving method according to the embodiment of the present disclosure in detail:
in step S110, source image data is acquired, the source image data including grayscale data of a plurality of image pixels.
The source image data may be sent by the control circuit to the display panel in response to a user's operation of the display panel to display a picture corresponding to the operation. Each image pixel may include a plurality of image sub-pixels of different colors, and the grayscale data for each image pixel includes a grayscale for each image sub-pixel. For example, each image pixel includes three image sub-pixels, namely, a red image sub-pixel, a green image sub-pixel and a blue image sub-pixel, and the gray scale data of the image pixel includes the gray scales of the red image sub-pixel, the green image sub-pixel and the blue image sub-pixel, which can be used as the source data of the display frame of the display panel.
The display panel can be used for an electronic device, the electronic device can be a mobile phone, a tablet computer and the like, the control circuit can be a mainboard circuit of the electronic device, the display panel is connected with the control circuit, and the control circuit can control the display panel to display images.
For example, a user clicks an icon displayed on the display panel to open a frame, and the control circuit may generate gray scale data of image pixels required for the frame in response to the operation. The screen may be a reading screen displaying characters, a non-reading screen displaying pictures, or the like, and is not particularly limited herein.
In step S120, a rendering mode corresponding to the source image data is determined according to the source image data as a target rendering mode, where the rendering mode at least includes a first rendering mode and a second rendering mode.
The rendering mode is as follows: and converting the source image data into the gray scale data of the sub-pixels according to the distribution mode of the sub-pixels of the display panel so as to display a corresponding picture. The rendering modes can be various, so that the rendering modes correspond to various conversion modes, and pictures corresponding to the same source image data can be displayed in different modes. Each Rendering mode may be implemented by a Sub-Pixel Rendering (SPR) method, and different Sub-Pixel Rendering methods are used for the different Rendering modes. The specific content of the sub-pixel rendering method is not particularly limited herein.
The rendering mode is multiple, that is, one of the rendering modes can be selected as a target rendering mode according to the source image data, so as to display the source image data on the display panel according to the target rendering mode. The rendering modes include at least two modes, i.e., a first rendering mode and a second rendering mode, wherein the first rendering mode and the second rendering mode are different modes and thus correspond to different sub-pixel rendering methods so as to display an image in the different modes. For example, the first rendering mode is used for displaying a non-reading picture, and the second rendering mode is used for displaying a reading picture.
The following is an exemplary description of determining a target rendering mode from the source image data:
in some embodiments of the present disclosure, the source image data may further include identification information, which may be a unique identification code or other information, as long as it is ensured that the identification information of different source image data is different.
Determining a rendering mode corresponding to the source image data as a target rendering mode according to the source image data, that is, step S120, including:
and determining a rendering mode corresponding to the identification information as a target rendering mode according to the identification information and a preset corresponding relation.
The corresponding relation between various kinds of identification information and various rendering modes can be established in advance, and after the identification information is obtained, the identification information can be compared with the identification information in the corresponding relation, so that the corresponding rendering mode is selected as the target rendering mode.
In other embodiments of the present disclosure, the identification information may also be calculated by a predetermined algorithm, and a code of a corresponding target rendering mode is determined, so that the target rendering mode is selected.
Step S130, converting the gray scale data of each image pixel into gray scale data of each sub-pixel of the display panel according to the target rendering mode, so as to generate a plurality of screen pixels corresponding to each image pixel one by one on the display panel, where each screen pixel includes a plurality of sub-pixels.
Since the number of image sub-pixels of an image pixel and the number of sub-pixels of a display panel may be different, the gray scale data of each image sub-pixel is not necessarily applied to each sub-pixel of the display panel in a one-to-one correspondence. The screen pixels are pixels of an image displayed by the display panel, which are formed by emitting light from sub-pixels of the display panel, and each screen pixel includes a plurality of screen sub-pixels of different colors. One sub-pixel of the display panel can be simultaneously used to form a plurality of screen pixels, i.e., at least two screen pixels share one sub-pixel of the display panel.
Through the conversion of the rendering mode, the gray scale data displayed by the shared sub-pixel is formed by overlapping the gray scale data of the screen sub-pixels with the same color of two adjacent screen pixels, and the overlapping mode can be that the sum or the weighted sum of the gray scale data of the screen sub-pixels with the same color of the two adjacent screen pixels is calculated to be displayed by one sub-pixel of the display panel, namely, the conversion of the gray scale data is realized through the color borrowing mode. Illustratively, the weighted sum is calculated as follows:
P-P1 × α + P2 × β, where P1 and P2 are gray scale data of screen sub-pixels of the same color of two adjacent screen pixels, α and β are weights of the gray scale data of the two screen sub-pixels, specific values of α and β are not particularly limited herein, and P is gray scale data of sub-pixels of the display panel.
As shown in fig. 2, fig. 2 exemplarily shows a principle of converting gray-scale data of an image pixel into gray-scale data of each sub-pixel of a display panel, and S rows in fig. 2 show the image pixels, each of which includes an R image sub-pixel, a B image sub-pixel, and a G image sub-pixel; the line D shows sub-pixels of the display panel, the sub-pixels of the line D are distributed into a first pixel unit and a second pixel unit which are arranged at intervals, the first pixel unit comprises an R sub-pixel and a G sub-pixel, and the second pixel unit comprises a B sub-pixel and a G sub-pixel. The gray scale data of the R image sub-pixels of two adjacent image pixels can be converted into the gray scale data of one R sub-pixel of the display panel for displaying.
In some embodiments of the present disclosure, as shown in fig. 3, the sub-pixels of the display panel include first, second, and third sub-pixels R, B, and G, which are different in color; all the sub-pixels are divided into a plurality of pixel units distributed in an array, and each pixel unit comprises a first sub-pixel R, a second sub-pixel B and two third sub-pixels G; the two third sub-pixels G of each pixel unit are distributed along the column direction, the second sub-pixel B is positioned between the first sub-pixel R and the third sub-pixel G along the row direction, and the arrangement mode of the sub-pixels of each pixel unit is the same.
As shown in fig. 3, the screen pixel X and the screen pixel Y are adjacent in the row direction and both include an R-screen sub-pixel, a G-screen sub-pixel, and a B-screen sub-pixel, and the screen pixel X and the screen pixel Y share one B sub-pixel of the display panel, and the grayscale data of the B sub-pixel is a weighted sum of the grayscale data of the two B-screen sub-pixels.
In the first rendering mode, any screen pixel and an adjacent screen pixel share one sub-pixel, namely, one-way color borrowing, at the moment, the displayed picture has small color shift and high saw tooth feeling, but the influence of the color shift is large for the picture, so that the method can be used for displaying non-reading pictures such as the picture.
In the second rendering mode, any screen pixel and a plurality of adjacent screen pixels share one sub-pixel, namely, the color borrowing is carried out in a plurality of directions, at the moment, the color deviation of the displayed picture is large, the saw tooth feeling is low, the influence of the color deviation is small because the color of the picture displaying the characters is single, the characters are usually black and the like, and the influence of the saw tooth feeling on the picture is large, so that the method can be used for displaying the reading picture with more characters.
Two adjacent screen pixels sharing the same subpixel are distributed in the row direction, but may be distributed in the column direction. Of course, they may also be distributed in other directions, i.e. in a direction inclined with respect to the row and column directions.
The row direction and the column direction herein only indicate two intersecting directions, and are not limited to a horizontal direction or a vertical direction, but if the row direction is the horizontal direction in the drawing, the column direction may be the vertical direction.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
