Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more specifically, to a pixel display method and related apparatus. Background Technology

[0002] With the increasing prevalence of AMOLED (Active-matrix organic light-emitting diode) displays, the mainstream resolution of AMOLED displays currently used in the market is Full High Definition (FHD) and above. As the resolution increases, the number of sub-pixels on the display also increases.

[0003] To reduce display costs and improve production yield, sub-pixel rendering (SPR) technology emerged. AMOLED displays produced using SPR employ a novel sub-pixel arrangement, reducing the number of subpixels to two-thirds that of traditional LCD (Liquid Crystal Display) displays while achieving the same resolution. Furthermore, Real RGB (true red, green, blue) images, after SPR processing, can achieve a visually similar Real RGB effect when displayed on this type of display. Examples of these novel sub-pixel arrangements include Diamond, Diamond-like (a variant of Diamond), and Delta RGB. Diamond and Diamond-like have become mainstream due to their superior display quality; in the following description, they are collectively referred to as Diamond arrangement. For Diamond arrangement, the sub-pixel data in the Real RGB original image is as follows: Figure 1 As shown in Figure (a), the sub-pixel data obtained after sub-pixel rendering processing of the original image is as follows: Figure 1 As shown in Figure (b), Figure 2 The specific arrangement of subpixels on the display screen is shown.

[0004] Due to factors in the display's driving circuitry, certain patterns may exhibit color shift when displayed on AMOLED displays with subpixels arranged in a diamond pattern. This is particularly noticeable with special patterns used to evaluate subpixel rendering performance; for example, large areas of alternating white and black lines with single or double spacing may show a noticeable green tint.

[0029] This disclosure has the following advantages or beneficial effects:

[0030] The pixel display method provided in this disclosure, when performing sub-pixel rendering processing on the original image to be displayed on the display screen, maps the green component of the white pixel in the original image to the green sub-pixel corresponding to the white pixel and the green sub-pixel surrounding the green sub-pixel on the display screen according to the display screen's color shift characteristics. In this way, the problem of white pixels appearing green is solved by dispersing the green component of the white pixel to the green sub-pixel surrounding the green sub-pixel corresponding to the white pixel, thereby reducing the green color. This solves the problem of green tint when white and black alternating lines are displayed on an AMOLED display screen with sub-pixels arranged in a diamond pattern. Attached Figure Description

[0031] The above and other objects, features, and advantages of this disclosure will become clearer from the following description of embodiments with reference to the accompanying drawings, in which:

[0032] Figure 1 Figure (a) shows the sub-pixel data in the original Real RGB image;

[0033] Figure 1 Figure (b) shows the sub-pixel data obtained after rendering the original image for the diamond arrangement of subpixels;

[0034] Figure 2 The diagram illustrates the specific arrangement of subpixels on an AMOLED display where subpixels are arranged in a diamond pattern.

[0035] Figure 3 An example of a single white dot display is shown based on an existing subpixel rendering interpolation algorithm for diamond arrangements;

[0036] Figure 4 A flowchart illustrating a pixel display method provided in one embodiment of this disclosure is shown;

[0037] Figure 5 An example of a single white dot display of a pixel display method provided according to an embodiment of the present disclosure is shown;

[0038] Figure 6 A structural block diagram of a pixel display device provided in another embodiment of this disclosure is shown. Detailed Implementation

[0039] The invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale. Furthermore, some well-known parts may not be shown in the drawings.

[0040] For AMOLED displays with subpixels arranged in a diamond pattern, if traditional interpolation algorithms are used during subpixel rendering of the original image, the processed image will exhibit color cast due to factors in the display's driving circuit. For example, if the driving voltage of the green subpixels is higher, large-area alternating white and black lines with single or double pixel intervals, commonly used to evaluate subpixel rendering performance, will show a noticeable green cast. Here, alternating white and black lines with single pixel intervals refer to alternating white and black lines where each line is one pixel wide, and alternating white and black lines with double pixel intervals refer to alternating white and black lines where each line is two pixels wide.

[0041] like Figure 2 As shown, in an AMOLED display where subpixels are arranged in a diamond pattern, the number of red and blue subpixels is equal, each being half the number of green subpixels. That is, compared to an LCD display where subpixels are arranged in a Real RGB pattern, the number of red and blue subpixels is halved, while the number of green subpixels remains unchanged.

[0042] Currently, the mainstream subpixel rendering interpolation algorithm for diamond subpixels requires color borrowing for red and blue subpixels, but not for green subpixels. Figure 3 This diagram illustrates a single white dot display example based on an existing subpixel rendering interpolation algorithm for diamond-shaped patterns. The two-digit numbers 00-22 (in bold) represent the input pixels in the subpixel rendering process, i.e., the pixels in the original image. Pixel 11 is an isolated white dot. The lowercase letters r, g, and b in parentheses immediately following the two-digit numbers, along with their respective subscript numbers, indicate the pixel values. The uppercase letters R, G, and B represent subpixels on the display screen, with their respective subscript numbers indicating the pixel values, i.e., the output results of the subpixel rendering process. For example... Figure 3 As shown, when a single white dot is displayed on the screen, it is mapped onto the subpixel within the dashed frame on the screen.

[0043] Specifically, Figure 3 The R in the upper left corner inside the dashed box 64 It is calculated by the weighted average of the red components of the pixels in the adjacent original image, as shown in formula (1), where R

[00] represents the red component of pixel 00, which is 0; R

[01] represents the red component of pixel 01, which is 0; R

[10] represents the red component of pixel 10, which is 0; and R

[11] represents the red component of pixel 11, which is 255.

[0044] R 64 = Mean (R

[00] + R

[01] + R

[10] + R

[11] ) (1)

[0045] Similarly, Figure 3 The R in the lower right corner inside the dashed box 64 It is calculated by the weighted average of the red components of the pixels in the adjacent original image, as shown in formula (2), where R

[11] represents the red component of pixel 11, which is 255; R

[12] represents the red component of pixel 12, which is 0; R

[21] represents the red component of pixel 21, which is 0; R

[22] represents the red component of pixel 21, which is 0.

[0046] R 64 = Mean (R

[11] + R

[12] + R

[21] + R

[22] ) (2)

[0047] as well as, Figure 3 The B in the upper right corner of the dashed box 64 It is calculated by the weighted average of the blue components of the pixels in the adjacent original image, as shown in formula (3), where B

[01] represents the blue component of pixel 01, which is 0; B

[02] represents the blue component of pixel 02, which is 0; B

[11] represents the blue component of pixel 11, which is 255; and B

[12] represents the blue component of pixel 12, which is 0.

[0048] B 64 = Mean (B

[01] + B

[02] + B

[11] + B

[12] ) (3)

[0049] Similarly, Figure 3 B in the lower left corner of the dashed box 64 It is calculated by the weighted average of the blue components of the pixels in the adjacent original image, as shown in formula (4), where B

[10] represents the blue component of pixel 10, which is 0; B

[11] represents the blue component of pixel 11, which is 255; B

[20] represents the blue component of pixel 20, which is 0; and B

[21] represents the blue component of pixel 21, which is 0.

[0050] B 64 = Mean (B

[10] + B

[11] + B

[20] + B

[21] ) (4)

[0051] In the above formulas (1), (2), (3) and (4), the symbol Mean represents the average calculation.

[0052] Figure 3 G at the center of the dashed box255 The green component of pixel 11, meaning the green component of the white dot in the original image, will only be mapped to one green sub-pixel on the display screen. It should be noted that in the existing sub-pixel rendering interpolation algorithm described above, the green component of any pixel in the original image is mapped to only one green sub-pixel on the display screen. For ease of description, the unique green sub-pixel on the display screen mapped to by the green component of a pixel in the existing sub-pixel rendering interpolation algorithm for diamond pixel arrangement will be referred to as the corresponding green sub-pixel. That is, for an AMOLED display with subpixels arranged in a diamond pattern, there is a one-to-one correspondence between the green sub-pixels on the display screen and the pixels in the original image.

[0053] As mentioned above, when a single white dot is displayed in the original image, only one green sub-pixel is lit on the screen, with a pixel value of the maximum value of 255. Therefore, if there is a defect in the display screen's driving circuit, and the driving voltage of the lit green sub-pixel is too high, the single white dot will appear greenish. If multiple white dots displayed in this way form a line, the entire line will appear greenish, meaning that alternating white and black lines will have a greenish tint.

[0054] To address the aforementioned issue of greenish tint in alternating black and white lines, this disclosure provides a pixel display method. Figure 4 The diagram shows a flowchart of a pixel display method provided in one embodiment of this disclosure. (Refer to...) Figure 4 Pixel display methods include:

[0055] Step S110: Obtain the original image to be displayed of the AMOLED display with subpixels arranged in a diamond pattern.

[0056] Step S120: When performing subpixel rendering processing on the original image to be displayed, the green component of the white pixel in the original image to be displayed is mapped to the green subpixel corresponding to the white pixel on the display screen and the green subpixel around the green subpixel, according to the green display characteristics of the display screen.

[0057] It should be noted that the green subpixels surrounding a green subpixel on the display screen refer to the green subpixels on the display screen corresponding to the pixels surrounding the pixel in the original image to which the green subpixel corresponds. In the original image, the pixels surrounding a pixel refer to the pixels that surround that pixel, that is, the eight pixels that are adjacent to the pixel and located above, below, left, right, upper left corner, upper right corner, lower left corner, and lower right corner of that pixel.

[0058] Step S130: The subpixel data obtained after subpixel rendering of the original image to be displayed is displayed on the display screen.

[0059] The pixel display method provided in this embodiment addresses the problem of white pixels appearing greenish by dispersing the green component of the white pixel to the green sub-pixels surrounding the green sub-pixels corresponding to the white pixel. This prevents the green component of the white pixel from becoming concentrated, thereby visually reducing the green component of the white pixel. This solves the problem of white and black alternating lines appearing greenish when displayed on an AMOLED display with sub-pixels arranged in a diamond pattern.

[0060] The pixel display method provided in the embodiments of this disclosure will be described in detail below.

[0061] In an optional embodiment, the green-biased display characteristic of the display screen includes: when the green component of the white pixel in the original image is only mapped to the green sub-pixel corresponding to the white pixel on the display screen during sub-pixel rendering processing, there exists an original image type with a green-biased display; step S120, according to the green-biased display characteristic of the display screen, maps the green component of the white pixel in the original image to be displayed to the green sub-pixel corresponding to the white pixel on the display screen and the green sub-pixels surrounding the green sub-pixel, including: determining the mapped green sub-pixels among the green sub-pixels surrounding the green sub-pixel according to the original image type, thereby achieving the effect that the original image is not green-biased overall when displayed on the display screen.

[0062] In the following description, the green sub-pixel on the display screen corresponding to the white pixel in the original image to be displayed on the display screen is called the central green sub-pixel, and the green sub-pixels mapped among the green sub-pixels surrounding the central green sub-pixel on the display screen are called newly added green sub-pixels.

[0063] In some examples, factors related to the display's driving circuitry cause the original image type to include only black and white horizontal lines with single-pixel intervals. Determining the addition of green sub-pixels based on the original image type includes identifying green sub-pixels located in the same column as and immediately adjacent to the central green sub-pixel. Specifically, if the central green sub-pixel is not located in the first or last row of the original image, the green sub-pixels located in the same column as and immediately adjacent to the central green sub-pixel are the two green sub-pixels located above and below the central green sub-pixel. In this example, in the black and white horizontal line pattern, the green components of each pixel in the single-pixel-wide white lines are dispersed along the column direction. Therefore, when the entire white line is displayed on the screen, the green color is visually reduced in the same dispersed manner, which helps to eliminate the green tint while achieving color uniformity.

[0064] In other examples, factors related to the display's driving circuitry cause the original image type to include only single-pixel-spaced black and white vertical lines. Determining the addition of green sub-pixels based on the original image type includes identifying green sub-pixels located in the same row as and immediately adjacent to the central green sub-pixel. Specifically, if the central green sub-pixel is not located in the first or last column of the original image, the green sub-pixels located in the same row as and immediately adjacent to the central green sub-pixel are the two green sub-pixels located to the left and right of the central green sub-pixel. In this example, in the pattern of black and white vertical lines, the green components of each pixel in the single-pixel-wide white lines are dispersed along the row direction. Therefore, when the entire white line is displayed on the screen, the green color is visually reduced in the same dispersed manner, which helps to eliminate the green tint while achieving color uniformity.

[0065] In some examples, factors related to the display's driving circuitry cause the original image type to only include horizontal and vertical black-and-white lines with single-pixel intervals. Determining the addition of a green sub-pixel based on the original image type involves identifying a first green sub-pixel and a second green sub-pixel as the new green sub-pixel. The first green sub-pixel is the one located in the same column as and adjacent to the central green sub-pixel, and the second green sub-pixel is the one located in the same row as and adjacent to the central green sub-pixel. This ensures that both the horizontal and vertical black-and-white lines with single-pixel intervals exhibit good color shift-free performance when displayed on the screen. Specifically, in this example, when a horizontal black-and-white line with single-pixel intervals is displayed on the screen, the final pixel value of the central green sub-pixel corresponding to a white pixel is the sum of the value of the green component of the white pixel mapped onto the central green sub-pixel and the value of the green component of the adjacent white pixels in the same row mapped onto the central green sub-pixel. Similarly, when the black and white vertical lines with single-pixel spacing are displayed on the screen in this example, the final pixel value of the central green sub-pixel corresponding to a white pixel is the sum of the value of the green component of the white pixel mapped to the central green sub-pixel and the value of the green component of the adjacent white pixels in the same column mapped to the central green sub-pixel.

[0066] It should be noted that in the examples above for black and white alternating horizontal lines and / or black and white alternating vertical lines, the green sub-pixels in the upper left, upper right, lower left, and lower right corners of the green sub-pixels surrounding the central green sub-pixel on the display screen are not used as newly added green sub-pixels. These four sub-pixels are reserved as green sub-pixels for use in more complex original image types to eliminate the corresponding green tint.

[0067] In another optional embodiment, the green tint characteristic of the display screen further includes: the color shift value when the display is green; step S120, mapping the green component of the white pixel in the original image to be displayed to the green sub-pixel corresponding to the white pixel and the green sub-pixel surrounding the green sub-pixel on the display screen according to the green tint characteristic of the display screen, further includes: configuring the pixel value of each mapped green sub-pixel according to the color shift value, so as to achieve more accurate elimination of color shift. Specifically, the mapped green sub-pixels include the central green sub-pixel and the newly added green sub-pixels. When the color shift value is large, the value mapped on the central green sub-pixel among the mapped green sub-pixels is smaller.

[0068] Furthermore, there are multiple original image types. Determining the new green sub-pixels based on the original image type can include: determining different green sub-pixels as new green sub-pixels based on different original image types; and configuring the pixel values ​​of each mapped green sub-pixel based on the color cast value can include: determining whether the color cast values ​​of different original image types are the same, and configuring different pixel values ​​for the green sub-pixels determined based on different original image types if they are not the same, so that the color cast of different original image types can be eliminated more accurately.

[0069] Furthermore, if the color cast values ​​of the different original image types are the same, then the same pixel value can be configured for the green sub-pixels determined according to the different original image types.

[0070] For example, if there are two types of original images, namely horizontal black-and-white lines with single-pixel intervals and vertical black-and-white lines with single-pixel intervals, the first green sub-pixel is determined as a newly added green sub-pixel based on the horizontal black-and-white lines with single-pixel intervals, and the second green sub-pixel is determined as a newly added green sub-pixel based on the vertical black-and-white lines with single-pixel intervals. In this case, if the color shift values ​​of the horizontal black-and-white lines with single-pixel intervals and the vertical black-and-white lines with single-pixel intervals are the same, then the first green sub-pixel and the second green sub-pixel are configured with the same pixel value; if the color shift values ​​of the horizontal black-and-white lines with single-pixel intervals and the vertical black-and-white lines with single-pixel intervals are different, then the first green sub-pixel and the second green sub-pixel are configured with different pixel values.

[0071] Furthermore, the pixel values ​​of each mapped green sub-pixel are configured according to the color shift value, including: configuring the central green sub-pixel to be 255 and the difference between the total pixel values ​​configured for each newly added green sub-pixel. In this way, the green component of the white pixels in the original image is not actually reduced, but is visually weakened by dispersion when displayed on the screen.

[0072] Figure 5 An example of a single white dot display according to an embodiment of the pixel display method provided in this disclosure is shown. (Refer to...) Figure 5 Compared to Figure 3The difference between the single white point display example shown and the one based on the existing subpixel rendering interpolation algorithm is: Figure 5 When pixel 11, which is a single white dot in the original image, is displayed on the screen, it is mapped to a sub-pixel on the screen (i.e., Figure 5 The number of sub-pixels enclosed by the dashed box increases. Figure 5 In the image, the central green sub-pixel corresponding to pixel 11 is labeled "G". 243 This means that the pixel value of the central green sub-pixel is 243, no longer 255; and the newly added green sub-pixel corresponding to pixel 11 is marked as "G3", there are four of them, and the pixel value of these four newly added green sub-pixels is configured to be 3, so that the sum of the pixel values ​​of the four newly added green sub-pixels and the pixel value of the central green sub-pixel is 255.

[0073] The pixel display method described above breaks away from the existing subpixel rendering interpolation algorithm for diamond-shaped arrangements, which requires only one green subpixel to be lit on the display screen for a single white dot in the original image. It solves the problem of green tint in the display of alternating white and black lines in the existing technology by dispersing the green component of the white pixel to the green subpixel around the green subpixel corresponding to the white pixel in the original image.
