Abstract
Description
Technical Field
[0001] This disclosure relates to the field of display technology, and more specifically, to a display method and display device for improving line sharpness. 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 will be 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 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] However, existing subpixel rendering interpolation algorithms for diamond-shaped pixel arrangements require color borrowing between red and blue subpixels. If a pixel in the original input image is pure red or pure blue, then adjacent pixels will also have red or blue subpixels lit up on the display screen. This can lead to insufficient differentiation in some scenarios. For example, when the original image consists of alternating red and black lines or alternating blue and black lines, the display on the screen will appear visually blurry and lack sharpness. Summary of the Invention
[0005] In view of this, the present disclosure provides a display method and display device for improving line sharpness in AMOLED displays with subpixels arranged in a diamond pattern, aiming to solve the problem that red-black or blue-black alternating lines are not sharp enough when displayed on such displays.
[0006] According to a first aspect of this disclosure, a display method for improving line sharpness is provided, wherein the lines are red lines in red-black alternating lines or blue lines in blue-black alternating lines, the display method comprising:
[0007] Obtain the original image to be displayed on the display screen, wherein the display screen is an active matrix organic light-emitting diode display screen in which the sub-pixels are arranged in a diamond arrangement;
[0008] When performing subpixel rendering on the original image to be displayed, the pixels within the lines in the original image to be displayed are mapped to subpixels with the same color as the pixel within the corresponding range on the display screen, and non-zero pixel values are configured for other subpixels within the corresponding range.
[0009] Furthermore, the sub-pixel data obtained after sub-pixel rendering of the original image to be displayed is displayed through the display screen.
[0010] Optionally, the other sub-pixels within the corresponding range are first color sub-pixels and second color sub-pixels;
[0011] Configuring non-zero pixel values for other sub-pixels within the corresponding range includes: configuring a non-zero first pixel value for the first color sub-pixel within the corresponding range, and configuring non-zero second pixel values for the two second color sub-pixels within the corresponding range, respectively.
[0012] Optionally, the first color is green, and the first pixel value is less than the second pixel value.
[0013] Optionally, the display method further includes:
[0014] Configure the sub-pixels of the line color on the display screen to the maximum pixel value;
[0015] Configure the first color sub-pixel and the second color sub-pixel on the display screen by using a pair of unused pixel values;
[0016] Determine whether the display screen displays the line color with purity and brightness within a preset range. If not, return to the step of configuring the first color sub-pixel and the second color sub-pixel on the display screen using an unused pair of pixel values. If yes, determine the currently used pair of pixel values as the first pixel value and the second pixel value.
[0017] Optionally, determining whether the display screen displays a line color with purity and brightness within a preset range includes: analyzing whether the color displayed on the display screen is a line color with purity and brightness within a preset range using a color analyzer.
[0018] Optionally, mapping the pixels within the lines of the original image to be displayed to sub-pixels of the same color as the pixel within the corresponding range on the display screen includes: configuring 1 / 4 of the pixel value of the pixel within the lines to sub-pixels of the same color as the pixel within the corresponding range on the display screen.
[0019] Optionally, the display method further includes: when performing subpixel rendering processing on the original image to be displayed, determining the pixel value of each subpixel on the display screen by summing the pixel values configured thereon.

[0025] This disclosure has the following advantages or beneficial effects:
[0026] The display method provided in this disclosure, when performing sub-pixel rendering processing on the original image to be displayed on the display screen, for the red lines in the red-black interval lines or the blue lines in the blue-black interval lines, not only maps the pixels within them to the sub-pixels with the same color as the corresponding pixel on the display screen, but also configures non-zero pixel values for other sub-pixels within the corresponding range. That is, by introducing sub-pixels of blue and green colors, the red in the red-black interval lines is distinguished, and similarly, by introducing sub-pixels of red and green colors, the blue in the blue-black interval lines is distinguished. This solves the problem of insufficient sharpness of red-black interval lines or blue-black interval lines when displayed on an AMOLED display screen arranged in a diamond pattern. Attached Figure Description

[0036] Figure 7 A structural block diagram of a display device provided in another embodiment of this disclosure is shown. Detailed Implementation
[0037] 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.
[0038] like Figure 2 As shown, in an AMOLED display with subpixels arranged in a diamond pattern, the number of red and blue subpixels is equal, each being half the number of green subpixels. This is compared to an LCD display with subpixels arranged in Real RGB, where the number of red and blue subpixels is halved, while the number of green subpixels remains unchanged. Currently, the mainstream subpixel rendering interpolation algorithm for diamond patterns requires red and blue subpixels to borrow color, while green subpixels do not. Because red and blue subpixels need to borrow color, if a pixel in the input image is pure red or pure blue, adjacent pixels will also have red or blue subpixels lit up on the display. This can lead to insufficient differentiation in some scenarios. For example, when the original image contains alternating red and black or blue and black lines, the red and blue areas displayed on the screen are not clearly separated, making the lines appear blurry and less sharp.
[0039] The following example uses alternating red and black lines. Figure 3 Figure (a) shows an exemplary single-pixel red-black alternating line, which is the original image without subpixel rendering processing; Figure 3 Figure (b) shows Figure 3 The image in Figure (a) shows a pixel-level display example of red and black alternating lines, where white dotted lines indicate the boundaries between pixels. Figure 3 In Figures (a) and (b), the diagonally filled areas represent the red areas. The aforementioned single-pixel red and black interval lines are the interval lines where both the red and black lines are a single pixel wide.
[0040] Figure 4 This diagram illustrates an example of red and black alternating lines displayed using an existing subpixel rendering interpolation algorithm for diamond patterns. The two-digit numbers 00-24 (in bold) represent the input pixels in the subpixel rendering process, i.e., the pixels in the original image. Specifically, pixels 00-04 represent a pure red line, pixels 10-14 represent a pure black line, and pixels 20-24 represent another pure red line. The lowercase letters r, g, and b in parentheses immediately following the two-digit numbers, along with the numbers immediately to their right, indicate the pixel value. The uppercase letters R, G, and B represent subpixels on the display screen, with the numbers in the lower right corner indicating the pixel value, i.e., the output result of the subpixel rendering process.
[0041] It should be noted that in existing subpixel rendering interpolation algorithms for diamond-shaped arrangements, each pixel in the original image has a corresponding range on the display screen during mapping. The corresponding range of one pixel on the display screen includes one green subpixel, two red subpixels, and two blue subpixels, such as... Figure 4 The dashed box shown indicates the corresponding range of pixel 12 on the display screen. As mentioned above, in the current subpixel rendering interpolation algorithm, green subpixels do not need to borrow color. That is, the green component of any pixel in the original image is mapped to only one green subpixel on the display screen. The green subpixels on the display screen and the pixels in the original image have a one-to-one correspondence. Therefore, the corresponding green subpixel of a pixel on the display screen and the four subpixels surrounding that green subpixel can be determined as the subpixels within the corresponding range of that pixel.
[0042] Furthermore, in current subpixel rendering interpolation algorithms, the process of mapping a pixel in the original image to the corresponding range on the display screen is as follows: the green component of the pixel is mapped to the only green subpixel within the corresponding range; the red component of the pixel is mapped to two red subpixels within the corresponding range, with each red subpixel mapping 1 / 4 of the pixel's red component; and the blue component of the pixel is mapped to two blue subpixels within the corresponding range, with each blue subpixel mapping 1 / 4 of the pixel's blue component. The pixel value of each subpixel on the display screen is the sum of the pixel values mapped to that subpixel.
[0043] Based on this Figure 4 On one pure red line, pixels 00-04 each have a red sub-pixel value of 128 within their corresponding range on the display screen. Similarly, on another pure red line, pixels 20-24 each have a red sub-pixel value of 128 within their corresponding range on the display screen. However, the green and blue sub-pixels within their respective ranges on the display screen for these two pure red lines each have a pixel value of 0. Taking red pixel 02 as an example, the lower right corner R within that range... 128 Specifically, it is calculated by formula (1), where the symbol Mean represents the average operation; R
[02] represents the red component of pixel 02, which is 255; R
[03] represents the red component of pixel 03, which is 255; R
[12] represents the red component of pixel 12, which is 0; R
[13] represents the red component of pixel 13, which is 0.
[0044] R 128 = Mean (R
[02] + R
[03] + R
[12] + R
[13] ) (1)
[0045] It should be noted that, Figure 4The image shows a display example of the middle section of the red and black interval lines. The red sub-pixel on the left edge of the entire red and black interval lines has a pixel value of 64, and the red sub-pixel on the right edge of the red and black interval lines also has a pixel value of 64.
[0046] The result obtained after processing by the sub-pixel rendering interpolation algorithm described above Figure 4 In the image, all red subpixels have a pixel value of 128, while all green and blue subpixels have a pixel value of 0. Therefore, visually, the black line between the two red lines is invisible, and only two adjacent red lines can be seen.
[0047] Figure 4 The image shows red and black alternating horizontal lines. Red and black alternating vertical and diagonal lines also suffer from the same problem: the black lines disappear during display, causing a decrease in the sharpness of the red lines. Furthermore, the same issue exists in patterns such as fonts formed by multiple red and black alternating horizontal, vertical, and diagonal lines. The same applies to blue and black alternating lines. Specifically, in the example displaying blue and black alternating lines using the existing subpixel rendering interpolation algorithm for diamond arrangements, the black line between the two blue lines is not visible; only two adjacent blue lines are visible.
[0048] To address the aforementioned issue of insufficient sharpness of red-black or blue-black interleaved lines when displayed on an AMOLED display with subpixels arranged in a diamond pattern, this disclosure provides a display method for improving line sharpness. The method aims to separate the red lines in red-black interleaved lines to improve their sharpness, and to separate the blue lines in blue-black interleaved lines to improve their sharpness.
[0049] Figure 5 The diagram shows a flowchart of a method for enhancing line sharpness according to an embodiment of this disclosure. For ease of description, the red lines in red-black alternating lines and the blue lines in blue-black alternating lines are collectively referred to as non-black lines. In other words, the non-black lines in the alternating lines described below specifically refer to the red lines in red-black alternating lines or the blue lines in blue-black alternating lines. (Refer to...) Figure 5 The display method includes:
[0050] Step S110: Obtain the original image to be displayed of the AMOLED display with subpixels arranged in a diamond pattern.
[0051] Step S120: When performing subpixel rendering processing on the original image to be displayed, the pixels within the non-black lines in the original image to be displayed are mapped to the subpixels with the same color as the pixel within the corresponding range on the display screen, and non-zero pixel values are configured for other subpixels within the corresponding range.
[0052] It should be noted that for red-black alternating lines, after any red pixel within a red line has a non-red sub-pixel within its corresponding range on the display screen configured with a non-zero pixel value, it must be ensured that although the red pixel on the display screen is not pure red, the hue of the displayed color is red and its purity and brightness are within the preset range, so that it still appears red visually. The same principle applies to blue-black alternating lines; that is, after any blue pixel within a blue line has a non-blue sub-pixel within its corresponding range on the display screen configured with a non-zero pixel value, it must be ensured that the hue of the displayed color is blue and its purity and brightness are within the preset range, so that it still appears blue visually.
[0053] Step S130: The subpixel data obtained after subpixel rendering of the original image to be displayed is displayed on the display screen.
[0054] The display method provided in this embodiment maps pixels within non-black lines in the original image to subpixels of the same color as the pixel within the corresponding range on the display screen, and configures non-zero pixel values for other subpixels within the corresponding range. In this way, the green subpixels within the corresponding range of the non-black pixel will light up, thereby distinguishing it from the case where the green subpixels within the corresponding range on the display screen are not lit when the pixels within the black lines in the original image are displayed. As a result, multiple non-black lines can be distinguished, and the sharpness of each non-black line is improved.
[0055] The following is a detailed description of the display method for improving line sharpness provided by the embodiments of this disclosure.
[0056] In an optional embodiment, the other sub-pixels within the corresponding range of the non-black pixel on the display screen are first color sub-pixels and second color sub-pixels. Step S120, configuring non-zero pixel values for the other sub-pixels within the corresponding range, includes: configuring a non-zero first pixel value for the first color sub-pixel within the corresponding range, and configuring non-zero second pixel values for the two second color sub-pixels within the corresponding range, i.e., configuring the first color sub-pixel with the first pixel value, and configuring the two second color sub-pixels with the same second pixel value, thereby helping to ensure the uniformity of the line color. Specifically, in red-black alternating lines, the other sub-pixels within the corresponding range of the non-black pixel on the display screen are two blue sub-pixels and one green sub-pixel, wherein the two blue sub-pixels are set to second pixel values, and the green sub-pixel is set to the first pixel value; in blue-black alternating lines, the other sub-pixels within the corresponding range of the non-black pixel on the display screen are two red sub-pixels and one green sub-pixel, wherein the two red sub-pixels are set to second pixel values, and the green sub-pixel is set to the first pixel value.
[0057] Furthermore, the first color is green, and the first pixel value is smaller than the second pixel value. Since the human eye is most sensitive to green light, this setting helps ensure that the color of pixels within non-black lines ultimately displayed on the screen is visually similar to the color of those non-black pixels.
[0058] Furthermore, the display method further includes: configuring the sub-pixels of non-black line colors on the display screen as the maximum pixel value; configuring a first color sub-pixel and a second color sub-pixel on the display screen using an unused pair of pixel values, that is, configuring one value of the unused pair of pixel values to the first color sub-pixel and the other value to the second color sub-pixel; then determining whether the display screen displays a non-black line color with saturation and brightness within a preset range, which can be done by analyzing the color displayed on the display screen using a color analyzer (e.g., CA410); otherwise, returning to the step of configuring the first color sub-pixel and the second color sub-pixel on the display screen using an unused pair of pixel values, and continuously adjusting the pixel values of the first color sub-pixel and the second color sub-pixel on the display screen until the display screen displays a non-black line color with saturation and brightness within the preset range. In this case, the currently used pair of pixel values is determined as the first pixel value and the second pixel value, that is, the pixel value of the current first color sub-pixel is determined as the first pixel value and the pixel value of the second color sub-pixel is determined as the second pixel value. The aforementioned preset range is set in advance, and colors with hues that are non-black line colors and saturation and brightness within the preset range are visually approximated as non-black line colors.
[0059] It should be noted that the requirements for color purity and brightness on the display screen vary in practice, therefore the above preset range can be set differently according to practical needs. Furthermore, due to factors in the display screen driver circuit, the first and second pixel values set on different displays within the same preset range may also differ. The above debugging process is performed based on practical experience and the actual conditions of the display screen, thereby determining the first and second pixel values to ensure that the red or blue displayed on the screen more closely matches the requirements.
[0060] In another optional embodiment, step S120, mapping the pixels within the lines of the original image to be displayed to sub-pixels of the same color as the pixel within the corresponding range on the display screen, includes: configuring 1 / 4 of the pixel value of the pixels within the non-black lines to sub-pixels of the same color as the pixel within the corresponding range on the display screen.
[0061] Furthermore, the above display method also includes: when performing subpixel rendering processing on the original image to be displayed, determining the pixel value of each subpixel on the display screen by summing the pixel values configured thereon.
[0062] Figure 6An example of a single-pixel red-black spaced horizontal line displaying a display method provided according to an embodiment of this disclosure is shown. (Refer to...) Figure 6 Compared to Figure 4 The difference between the example shown here, which displays a single-pixel red-black spaced horizontal line based on existing subpixel rendering interpolation algorithms, is that: Figure 6 In the original image, the red pixels 00-04 and 20-24 each have not only red sub-pixels lit up within their corresponding ranges on the display screen, but also green and blue sub-pixels. In this example, the green sub-pixel is the first color sub-pixel mentioned above, and its first pixel value is configured as 3; while the blue sub-pixel is the second color sub-pixel mentioned above, and its second pixel value is configured as 5. Figure 6 In the original image, the black pixels 10-14 each have corresponding green sub-pixels that are not lit on the screen, thus distinguishing them from the red sub-pixels 00-04 and 20-24. As a result, the red lines on the screen are separated and no longer stick together.
[0063] It should also be noted that Figure 6 The image shows a display example of the middle section of the red and black interval lines. The red sub-pixel on the left edge of the entire red and black interval lines has a pixel value of 64, and the red sub-pixel on the right edge of the red and black interval lines also has a pixel value of 64.
[0064] The display method provided in this embodiment is applied to red and black alternating lines to separate the red lines in the red and black alternating lines, thereby improving the sharpness of the red lines. The red and black alternating lines may include one or more of the following: red and black alternating horizontal lines, red and black alternating vertical lines, and red and black alternating diagonal lines. In many cases, they may be combined to form fonts or other patterns. The width of the red lines in the red and black alternating lines may be a single pixel or multiple pixels, and the width of the black lines may also be a single pixel or multiple pixels.
[0065] The display method provided in this embodiment is applied to blue-black interval lines to separate the blue lines in the blue-black interval lines, thereby improving the sharpness of the blue lines. The blue-black interval lines may include one or more of the following: blue-black interval horizontal lines, blue-black interval vertical lines, and blue-black interval diagonal lines. In many cases, they may be combined to form fonts or other patterns. The width of the blue lines in the blue-black interval lines may be a single pixel or multiple pixels, and the width of the black lines may also be a single pixel or multiple pixels.
[0066] The display methods for improving line sharpness provided above, for red-black alternating lines, separate adjacent red lines by lighting up the green and blue sub-pixels within the corresponding range of the red pixels in the original image on the display screen, thereby improving the sharpness of the red lines; similarly, for blue-black alternating lines, separate adjacent blue lines by lighting up the green and red sub-pixels within the corresponding range of the blue pixels in the original image on the display screen, thereby improving the sharpness of the blue lines.
