In order to facilitate understanding of the present application, first, a brief description will be made of an application scenario related to the present application.
The basic display unit of an image is a pixel point, and the quality of the image is mainly influenced by the physical density of the pixel point (namely, the resolution of the image). Each pixel point represents the color attribute through the intensity values of the three primary colors of red, green and blue.
The basic display unit of the display panel is a pixel unit, and each pixel unit includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B as an example. The display effect of the display panel is mainly affected by the pixel cell density (i.e., the number of pixel cells per unit area). The display effect of the display panel can be changed by adjusting the distribution and/or arrangement of R, G, B sub-pixels on the display panel. FIG. 1a shows a schematic diagram of a first arrangement of sub-pixels; fig. 1b shows a schematic diagram of a second arrangement of sub-pixels.
In some embodiments of the display panel, as shown in fig. 1a, each R, G, B sub-pixel combination is arranged as a light group P, i.e., each light group P is a pixel unit. In this case, the pixels on the image correspond one by one to the lamp group P on the display panel, and thus the color and brightness of each pixel on the image can be accurately presented. However, since each sub-pixel needs to correspond to one LED lamp bead, the number of required LED lamp beads is large, and the cost is correspondingly high. And limited by the development of LED lamp bead assembly technology, the maximum resolution that can be supported by this type of display panel is comparatively limited.
In some embodiments of the display panel, as shown in FIG. 1b, each subpixel on the display panel is arranged separately. In fig. 1b, the odd-numbered rows of subpixels illustratively include R and G alternately arranged; the even-numbered rows of sub-pixels include G and B alternately arranged, and each sub-pixel is different in emission color from its adjacent sub-pixel. Each sub-pixel can form different pixel units with adjacent sub-pixels according to different combination modes, and display data of the sub-pixel is obtained through a rendering algorithm of pixel image data corresponding to the pixel units. In the display process, a picture is overlapped in human eyes by utilizing the persistence of vision of human eyes in cooperation with a scanning driving technology. Thus higher resolution display can be achieved with fewer lamp beads and lower power consumption.
In the display panel shown in fig. 1b, each pixel is displayed as a "virtual image point" formed by the phenomenon of human eye persistence of vision during the display process, and thus these pixel units are also referred to as virtual pixel units. And the color and brightness of the image pixel point cannot be accurately restored due to the 'virtual image point', and particularly, the problems of blurring and distortion occur when images such as characters, horizontal lines, vertical lines and the like are displayed.
Fig. 2 shows a schematic flow chart of a data processing method according to a first embodiment of the present application, and as shown in fig. 2, the data processing method provided by the present application includes the following steps:
Step S10, acquiring an image;
The image is composed of a plurality of pixel points, and each pixel point is composed of three colors of red, green and blue, and the color attribute of the pixel point is changed by adjusting the mixing proportion of the three colors of red, green and blue. Accordingly, the image data includes RGB values corresponding to each pixel point. Taking 8-bit image color (i.e. 256 levels of display color) as an example, if R, G, B values of a certain pixel point are (0, 0), the pixel point is black; if R, G, B of a pixel is (0, 255, 0), the pixel is green; if R, G, B of a pixel is (255, 255, 255), it indicates that the pixel is white.
Step S20, selecting a display mode;
In an embodiment of the present application, a display mode is determined according to display contents of an image. In an embodiment of the application, the display modes include a first display mode and a second display mode. When the display content of the image does not comprise any one of characters, horizontal lines and vertical lines, selecting a first display mode; when the display content of the image includes at least one of text, horizontal lines, vertical lines, then a second display mode is selected. The first display mode and the second display mode will be described in detail below.
Step S30, determining a plurality of pixel units of the display panel according to the selected display mode;
The display panel includes a plurality of sub-pixels arranged according to a preset rule.
The basic display unit of the display panel is a pixel unit, and each pixel unit corresponds to a corresponding pixel point on an image and comprises a plurality of corresponding sub-pixels.
Wherein, in the first display mode, at least one sub-pixel is shared by a plurality of pixel units; in the second display mode, each sub-pixel is included in only a corresponding one of the pixel units. For convenience of description, the pixel unit determined in the first display mode is referred to as a first pixel unit, and the pixel unit determined in the second display mode is referred to as a second pixel unit. And, for example, each of the first/second pixel units includes sub-pixels of three colors of red, green, and blue.
FIG. 3 shows a schematic diagram of a first display mode; fig. 4 shows a schematic diagram of a second display mode. The first display mode and the second display mode are further described below with reference to fig. 3 and 4.
The display panel includes, for example, a plurality of red sub-pixels R, a plurality of green sub-pixels G, and a plurality of blue sub-pixels B. The sub-pixels are arranged according to a preset rule. Illustratively, in fig. 3 or 4, the odd-numbered row subpixels of the display panel include red subpixels R and green subpixels G alternately arranged; the even-numbered row sub-pixels include green sub-pixels G and blue sub-pixels B alternately arranged, and for each sub-pixel, the color corresponding to the sub-pixel is different from the color corresponding to the sub-pixel adjacent in the horizontal direction or the vertical direction.
In the first display mode, each first pixel unit comprises R, G, B sub-pixels with three colors, and each sub-pixel is shared by a plurality of first pixel units. In some embodiments, referring to fig. 3, each first pixel unit includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B according to the arrangement of the sub-pixels on the display panel. Each red sub-pixel R/blue sub-pixel B is shared by four first pixel units, for example, for the blue sub-pixel B22 of the second row and the second column, the blue sub-pixel B22 is shared by four first pixel units P11, P12, P21, P22. Each green sub-pixel G is shared by two first pixel units, for example, for a green sub-pixel G23 of the second row and the third column, the green sub-pixel G23 is shared by two first pixel units P13 and P23.
In the second display mode, each second pixel unit comprises R, G, B sub-pixels with three colors, and each sub-pixel and only one second pixel unit corresponds to the sub-pixel. In some embodiments, referring to fig. 4, each of the second pixel units includes one red sub-pixel R, two green sub-pixels G, and one blue sub-pixel B according to the arrangement of the sub-pixels on the display panel.
It should be noted that, in the embodiment provided in the present application, the sub-pixels included in the first pixel unit/the second pixel unit are determined according to the arrangement manner of the sub-pixels on the display panel, but in the embodiment of the present application, the specific number of the sub-pixels of each color in each first pixel unit/second pixel unit is not limited (i.e., each first pixel unit/second pixel unit includes at least one red sub-pixel R, at least one green sub-pixel G, and at least one blue sub-pixel B). However, it should be appreciated that in some embodiments, the number of sub-pixels in a single first pixel cell/second pixel cell should be minimized to increase the number of first pixel cells/second pixel cells per unit area, thereby improving display quality.
Step S40, determining the mapping relation between each sub-pixel and each pixel point according to the mapping relation between each pixel unit and each pixel point;
The display process of the display panel is a mapping process of image data of each pixel point on the image to display data of each sub-pixel on the display panel. In the step, the mapping relation between each sub-pixel and the corresponding pixel point is determined according to the mapping relation between the pixel unit to which the sub-pixel belongs and the pixel point.
In the first display mode, each sub-pixel is shared by a plurality of first pixel units, and thus each sub-pixel corresponds to a plurality of adjacent pixel points on the image; in the second display mode, each sub-pixel has only one corresponding second pixel unit, and thus each sub-pixel corresponds to one pixel point on the image.
It should be noted that, since the resolution of the image is generally fixed, but the number of pixel units is different in different division modes, in some embodiments, further processing of the image is required, for example, the processing method includes scaling the image so that the number of pixel points on the image corresponds to the number of the first pixel units/the second pixel units, so as to determine the mapping relationship between each sub-pixel and the pixel point of the image.
Step S50, calculating display data of each sub-pixel according to the image data of the pixel point corresponding to the sub-pixel;
In the first display mode, each sub-pixel corresponds to a plurality of adjacent first pixel units, that is, a plurality of adjacent pixel points in the image, and display data of the sub-pixel is calculated based on the plurality of pixel point image data. In some embodiments, the display data of the sub-pixel may be obtained by a pixel rendering algorithm based on image data of each pixel point corresponding to a plurality of pixel units corresponding to the sub-pixel.
In the second display mode, each sub-pixel corresponds to a second pixel unit, that is, corresponds to a pixel point in the image, so that the display data of the sub-pixel is determined according to the image data of the pixel point.
According to the data processing method provided by the application, different display modes are selected to determine a plurality of pixel units on the display panel, and one sub-pixel corresponds to one/a plurality of pixel units and each pixel unit corresponds to one pixel point on an image under different display modes, so that the mapping mode of the sub-pixel and the pixel point can be flexibly selected, and the display quality is improved.
Further, in some embodiments, after the image is acquired in step S10, the method further includes the steps of: an image is divided into a plurality of sub-images. In this step, the image is divided into a plurality of sub-images according to a preset image dividing method. It should be understood, however, that the present application is not limited to a particular method of sub-image division, for example, in some embodiments, an image may be divided into a plurality of sub-images according to a preset size for ease of calculation; in other embodiments, the image may also be partitioned according to features (e.g., color, texture, shape) of the image to obtain multiple sub-images.
Correspondingly, the step S20 comprises a display step of determining a display panel and a sub-region corresponding to each sub-image according to the display content of each sub-image; when the sub-image display content does not include any one of text, horizontal lines, and vertical lines, a plurality of first pixel units are determined on the display panel in a sub-region corresponding to the sub-image, and at least one sub-pixel is shared by the plurality of first pixel units. When the sub-image display content includes at least one of text, horizontal lines, and vertical lines, a plurality of second pixel units are determined on the display panel corresponding to the sub-image sub-region, and each sub-pixel is included in only a corresponding one of the second pixel units.
And accordingly, step S30 includes determining a plurality of pixel units of each sub-region of the display panel according to a display mode of the sub-region.
The image is divided into a plurality of sub-images, and the display mode of the sub-image in the corresponding area on the display panel is determined according to the display content of each sub-image, so that the degree of distinction of the pixel edges is better for the sub-images with the display content comprising the content of display characters, horizontal lines, vertical lines and the like; for the sub-images with display contents not including contents such as display characters, horizontal lines, vertical lines and the like, the resolution of display is higher, and the display effect is improved as a whole.
Fig. 5 shows a schematic structural diagram of a data processing apparatus according to a second embodiment of the present application. As shown in fig. 5, the data processing apparatus 100 provided by the present application includes a selecting unit 130, a mapping unit 140, and a calculating unit 150.
And a selection unit 130 for selecting a display mode of the display panel to determine a plurality of pixel units of the display panel according to the display mode. The display panel comprises a plurality of sub-pixels arranged according to a preset rule, and each pixel unit corresponds to a corresponding pixel point on the image and comprises a plurality of corresponding sub-pixels. The display mode includes a first display mode in which at least one sub-pixel is shared by a plurality of pixel units, and a second display mode in which each sub-pixel is included in only a corresponding one of the pixel units. The first display mode, the second display mode, the first pixel unit corresponding to the first display mode, and the second pixel unit corresponding to the second display mode are described in detail above, and are not described herein.
The mapping unit 140 is connected to the selecting unit 130, and determines the mapping relationship between each sub-pixel and each pixel according to the mapping relationship between each pixel and each pixel. In the first display mode, each sub-pixel is shared by a plurality of first pixel units, and thus each sub-pixel corresponds to a plurality of adjacent pixel points on the image; in the second display mode, each sub-pixel has only one corresponding second pixel unit, and thus each sub-pixel corresponds to one pixel point on the image.
It should be noted that, since the resolution of the image is generally fixed, but the number of pixel units is different in different division modes, in some embodiments, further processing of the image is required, for example, the processing method includes scaling the image so that the number of pixel points on the image corresponds to the number of the first pixel units/the second pixel units, so as to determine the mapping relationship between each sub-pixel and the pixel point of the image.
The calculating unit 150 is connected to the mapping unit 140, and calculates display data of each sub-pixel according to image data of a pixel point corresponding to the sub-pixel. In the first display mode, each sub-pixel corresponds to a plurality of adjacent first pixel units, that is, a plurality of adjacent pixel points in the image, and display data of the sub-pixel is calculated based on the plurality of pixel point image data. In some embodiments, the display data of the sub-pixel may be obtained by a pixel rendering algorithm based on image data of each pixel point corresponding to a plurality of pixel units corresponding to the sub-pixel.
In some embodiments, the selection unit 130 detects display contents of the image to select a corresponding display mode. When the display content of the image does not comprise any one of characters, horizontal lines and vertical lines, determining a pixel unit according to the first display mode; when the display content of the image comprises any one of characters, horizontal lines and vertical lines, the pixel unit is determined according to the second display mode.
The data processing device thus further comprises an input unit 110 connected to the selection unit 130 for acquiring images. The image is composed of a plurality of pixel points, each pixel point is composed of three colors of red, green and blue, and each pixel point is enabled to display corresponding colors by adjusting the mixing proportion of the three colors of red, green and blue. Accordingly, the image data includes RGB values corresponding to each pixel point. Taking 8-bit image color (i.e. 256 levels of display color) as an example, if R, G, B values of a certain pixel point are (0, 0), the pixel point is black; if R, G, B of a pixel is (0, 255, 0), the pixel is green; if R, G, B of a pixel is (255, 255, 255), it indicates that the pixel is white.
According to the data processing method and the processing device, different display modes are selected to determine the plurality of pixel units on the display panel, and one sub-pixel corresponds to one/more pixel units and each pixel unit corresponds to one pixel point on an image under different display modes, so that the mapping mode of the sub-pixel and the pixel point can be flexibly selected, and the display quality is improved.
In some embodiments, in order to improve the overall display effect of the picture to be displayed, a processing unit 120 is further included between the input unit 110 and the selection unit 130, for dividing the image into a plurality of sub-images according to a preset image dividing method. The selection unit 130 thus determines the display mode of the display panel and the sub-region corresponding to each sub-image according to the display content of the sub-image, and determines the plurality of pixel units of the sub-region according to each sub-region display mode. It should be noted that the present application is not limited to a specific method of dividing the sub-image, for example, in some embodiments, for simplicity of calculation, the image may be divided into a plurality of sub-images according to a preset size; in other embodiments, the image may also be partitioned according to features (e.g., color, texture, shape) of the image to obtain multiple sub-images.
The image is divided into a plurality of sub-images, and the display mode of the sub-image in the corresponding sub-region on the display panel is determined according to the display content of each sub-image, so that the degree of distinction of the pixel edges is better for the sub-images with the display content comprising the content of display characters, horizontal lines, vertical lines and the like; for the sub-images with display contents not including contents such as display characters, horizontal lines, vertical lines and the like, the resolution of display is higher, and the display effect is improved as a whole.
Further, since the resolution of the image is generally fixed, but the number of pixel units is different in different division modes, in some embodiments, the processing unit 120 further needs to perform further processing on the image, for example, scaling the image, so that the number of pixel points on the image corresponds to the number of the first pixel units/the second pixel units, so as to determine the mapping relationship between each sub-pixel and the pixel point of the image.
In addition, the application also provides a chip comprising the data processing device, so that the chip has the beneficial effects and is not repeated herein.
