Description

Technical Field

[0001] This application relates to the field of display technology, and more specifically, to a method, apparatus, and display device for removing color patterns. Background Technology

[0002] With the continuous development of display technology, users' demands for display devices are also constantly increasing. Users' expectations for display devices are no longer limited to simply increasing screen size, but extend to improvements in aspects such as color performance, resolution, brightness, contrast, and dynamic image quality. Against this backdrop, glasses-free 3D display technology has gradually gained widespread attention. This technology provides users with a more realistic and immersive visual experience through optical design and image processing, becoming one of the important directions for the differentiated development of display device products.

[0003] However, when a display device performs glasses-free stereoscopic display, a phenomenon called viewpoint pattern may appear on the screen. This viewpoint pattern may affect the display effect of glasses-free display and thus reduce the user's visual experience. Summary of the Invention

[0004] This application provides a method, apparatus, and display device for removing color patterns, which can reduce or even eliminate color patterns that appear on the display device when it is displayed without glasses, thereby improving the display effect of the display device without glasses.

[0005] In a first aspect, a method for removing color patterns is provided, the method comprising: obtaining a viewpoint mapping map of a display panel, the viewpoint mapping map including the correspondence between pixels of the display panel and viewpoints, the pixels including multiple sub-pixels;

[0006] Based on the viewpoint mapping, the number and arrangement order of sub-pixels corresponding to the first viewpoint within the first viewpoint period are determined; based on the number and arrangement order of sub-pixels corresponding to the first viewpoint within the first viewpoint period, the grayscale values ​​of the sub-pixels within the first viewpoint period are adjusted to control the brightness of the sub-pixels within the first viewpoint period.

[0007] In this embodiment, by adjusting the number and arrangement order of sub-pixels of the first viewpoint within the first viewpoint period, the grayscale values ​​of the sub-pixels within the first viewpoint period can be adjusted so that the brightness values ​​of different types of sub-pixels corresponding to the first viewpoint remain relatively similar, thereby reducing or even eliminating color patterns caused by differences in brightness of various sub-pixels, thus improving the naked-eye display effect of the display device.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the sub-pixel corresponding to the first viewpoint includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. The number of the first sub-pixel is a first value, the number of the second sub-pixel is a second value, and the number of the third sub-pixel is a third value. Adjusting the grayscale value of the sub-pixel within the first viewpoint period according to the number and arrangement order of the sub-pixels includes: when the first value is greater than the second value and the second value is equal to the third value, adjusting the grayscale value of the first sub-pixel within the first viewpoint period according to the arrangement order of the sub-pixels corresponding to the first viewpoint within the first viewpoint period; or, when the first value is less than the second value and the second value is equal to the third value, adjusting the grayscale values ​​of the second sub-pixel and the third sub-pixel within the first viewpoint period according to the arrangement order of the sub-pixels corresponding to the first viewpoint within the first viewpoint period.

[0009] In this embodiment, when the number of the first sub-pixel differs from the number of other sub-pixels within the first viewpoint period, the grayscale value of the first sub-pixel, or the grayscale values ​​of the second and third sub-pixels, are adjusted to keep the brightness values ​​of different types of sub-pixels relatively similar. In this way, the color patterns caused by the brightness differences of various sub-pixels can be reduced or even eliminated more efficiently, thereby improving the overall display effect and user experience of the display device in naked-eye 3D display scenarios.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the arrangement order of the sub-pixels includes: the arrangement order of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the second first sub-pixel. Adjusting the grayscale value of the first sub-pixel within the first viewpoint period according to the arrangement order of the sub-pixels includes: setting the grayscale value of the first sub-pixel or the second first sub-pixel to 0.

[0011] In this embodiment of the application, during the first viewpoint period, when the number of first sub-pixels corresponding to the first viewpoint is greater than the number of second or third sub-pixels, by setting the grayscale value of the first or second sub-pixel to 0, the brightness values ​​of different types of sub-pixels can be made the same. In this way, the color patterns caused by the brightness differences of various sub-pixels can be reduced or even eliminated simply and efficiently, ensuring the color consistency and visual comfort of the display device screen.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the arrangement order of the sub-pixels includes: the arrangement order of a first sub-pixel, a second sub-pixel, a third sub-pixel, and a second first sub-pixel. Adjusting the grayscale value of the first sub-pixel within the first viewpoint period according to the arrangement order of the sub-pixels includes: assigning the grayscale value of the first sub-pixel corresponding to the image of the first viewpoint to the first first sub-pixel and the second first sub-pixel, so that the sum of the brightness values ​​of the first first sub-pixel and the second first sub-pixel is equal to the brightness value of the second sub-pixel or the third sub-pixel.

[0013] In this embodiment, when the number of first sub-pixels corresponding to the first viewpoint is greater than the number of second or third sub-pixels, by adjusting the distribution of grayscale values ​​of the first sub-pixels, the sum of the brightness values ​​of the first and second sub-pixels can be made equal to the brightness value of the second or third sub-pixels. In this way, the color patterns caused by the brightness differences of various sub-pixels can be reduced or even eliminated more effectively, thereby improving the color consistency and uniformity of the displayed image and further improving the user's stereoscopic viewing experience.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, determining the arrangement order of the sub-pixels corresponding to the first viewpoint within the first viewpoint period based on the viewpoint mapping includes: determining the position coordinates of the sub-pixels corresponding to the first viewpoint based on the position of the sub-pixels corresponding to the first viewpoint in the viewpoint mapping and the tilt angle of the lens in the display panel; and determining the arrangement order of the sub-pixels corresponding to the first viewpoint based on the position coordinates of the sub-pixels corresponding to the first viewpoint.

[0015] In this embodiment, by using the position of the sub-pixel corresponding to the first viewpoint in the viewpoint mapping map and the tilt angle of the lens, the position coordinates of the sub-pixel corresponding to the first viewpoint can be accurately and efficiently determined, thereby determining the arrangement order of the sub-pixels corresponding to the first viewpoint, thus providing a premise and foundation for subsequent adjustment of the brightness of the sub-pixels within the first viewpoint period.

[0017] In this embodiment, the viewpoint mapping can be accurately and efficiently determined based on the lens parameters and the number of viewpoints, thus providing a basis for subsequently determining the number and arrangement order of sub-pixels corresponding to the first viewpoint.

[0041] In the description of the embodiments in this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. In this application, "at least one" means one or more, and "more than one" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of a single item or multiple items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0042] The use of prefixes such as "first" and "second" in this application embodiment is solely for distinguishing different descriptive objects and does not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes to distinguish descriptive objects in this application embodiment does not constitute a limitation on the described objects. The description of the described objects is found in the claims or the context of the embodiments, and the use of such prefixes should not constitute unnecessary restrictions.

[0043] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0044] As described in the background section, naked-eye 3D display technology has gradually attracted widespread attention. This technology provides users with a more realistic and immersive visual experience through optical design and image processing, and has become one of the important directions for the differentiated development of display device products.

[0045] However, when a display device performs glasses-free stereoscopic display, a phenomenon called viewpoint pattern may appear on the screen. This viewpoint pattern may affect the display effect of glasses-free display and thus reduce the user's visual experience.

[0046] For example, Figure 1 This is a schematic diagram illustrating the display device displaying 3D color patterns according to an embodiment of this application. Figure 2 This is a schematic diagram illustrating the display device displaying 2D colored patterns according to an embodiment of this application. For example... Figure 1 and Figure 2 As shown, when a display device performs glasses-free 3D stereoscopic display, phenomena such as 3D single-viewpoint color patterns or 2D single-viewpoint color patterns may appear on the screen. The appearance of these patterns can easily disrupt the color uniformity and stereoscopic effect of the image, thus affecting the overall effect of the glasses-free display. If this phenomenon is not effectively suppressed, it will not only cause users to experience obvious color unevenness and image quality degradation during viewing, but may also reduce visual comfort, thereby significantly reducing the glasses-free 3D display performance of the display device and the user's immersive experience.

[0047] Based on this, embodiments of this application provide a method, apparatus, and display device for removing color patterns, which can reduce or even eliminate color patterns that appear on the display device when it is displayed without glasses, thereby improving the display effect of the display device without glasses.

[0048] Figure 3 This is a schematic flowchart of a color pattern removal method provided in an embodiment of this application. Method 300 may include steps S301 to S303.

[0049] S301, Obtain the viewpoint map of the display panel.

[0050] The viewpoint map can include the correspondence between pixels on the display panel and viewpoints, and each pixel includes multiple sub-pixels.

[0051] For example, Figure 4 This is a schematic diagram of a viewpoint mapping provided in an embodiment of this application, such as... Figure 4As shown, the viewpoint map includes red, green, and blue sub-pixels. Numbers 1 to 24 represent different viewpoints; each number corresponds to a specific viewing direction or position. Viewers at different spatial locations can receive the viewpoint image corresponding to that number, thus achieving a continuous and smooth stereoscopic visual effect. Figure 4 The viewpoint map shown includes the correspondence between sub-pixels of different colors and viewpoints.

[0052] S302, Based on the viewpoint mapping, determine the number and arrangement order of sub-pixels corresponding to the first viewpoint within the first viewpoint period.

[0053] Optionally, the number of viewpoint periods included in the viewpoint map is not limited in this application, and the number of viewpoint periods can be flexibly set based on the scenario to which the color texture removal method is applicable. For example, the viewpoint map may include two viewpoint periods.

[0054] Optionally, the number of viewpoints in a viewpoint cycle is not limited in this application. The number of viewpoints can be flexibly set based on the scenario to which the color texture removal method is applicable. For example, no more than 100 viewpoints can be set in a viewpoint cycle.

[0055] For example, the first viewpoint can be any viewpoint within the first viewpoint period. For instance, when the viewpoint map includes 24 viewpoints, the first viewpoint can be any one of viewpoints 1 to 24. The sub-pixels corresponding to the first viewpoint can include red sub-pixels, blue sub-pixels, or green sub-pixels. The arrangement order of the sub-pixels corresponding to the first viewpoint can be understood as the order and / or coordinates in which the red sub-pixels, blue sub-pixels, or green sub-pixels corresponding to the first viewpoint appear in the first viewpoint period.

[0056] S303, adjust the grayscale value of the sub-pixels in the first viewpoint period according to the number and arrangement order of the sub-pixels corresponding to the first viewpoint in the first viewpoint period, so as to control the brightness of the sub-pixels in the first viewpoint period.

[0057] Based on the above-mentioned color pattern removal method, by adjusting the number and arrangement order of sub-pixels of the first viewpoint within the first viewpoint period, the grayscale values ​​of sub-pixels within the first viewpoint period can be adjusted so that the brightness values ​​of different types of sub-pixels corresponding to the first viewpoint remain relatively similar, thereby reducing or even eliminating color patterns caused by differences in brightness of various sub-pixels, thus improving the naked-eye display effect of the display device.

[0058] It should be noted that the colored stripes involved in this application may refer to colored stripes produced by uneven color distribution on the display panel, excluding moiré patterns or monochrome stripes.

[0059] It should also be noted that the color pattern removal method involved in this application is applicable to LCD display scenarios, OLED display scenarios, or Micro LED display scenarios.

[0060] According to some embodiments, the sub-pixels corresponding to the first viewpoint include a first sub-pixel, a second sub-pixel, and a third sub-pixel. The number of the first sub-pixels is a first value, the number of the second sub-pixels is a second value, and the number of the third sub-pixels is a third value. Then, step S303 includes: when the first value is greater than the second value and the second value is equal to the third value, adjusting the grayscale value of the first sub-pixel in the first viewpoint period according to the arrangement order of the sub-pixels corresponding to the first viewpoint in the first viewpoint period; or, when the first value is less than the second value and the second value is equal to the third value, adjusting the grayscale value of the second or third sub-pixel in the first viewpoint period according to the arrangement order of the sub-pixels.

[0061] Based on the above-mentioned color pattern removal method, when the number of the first sub-pixel is different from the number of other sub-pixels within the first viewpoint period, the grayscale value of the first sub-pixel, or the grayscale values ​​of the second and third sub-pixels, can be adjusted to keep the brightness values ​​of different types of sub-pixels relatively similar. In this way, the color patterns caused by the brightness differences of various sub-pixels can be reduced or even eliminated more efficiently, thereby improving the overall display effect and user experience of the display device in naked-eye 3D display scenarios.

[0062] Optionally, the first sub-pixel, the second sub-pixel, and the third sub-pixel may have different colors. For example, the first sub-pixel may be a red sub-pixel, the second sub-pixel may be a green sub-pixel, and the third sub-pixel may be a blue sub-pixel.

[0063] For example, adjusting the brightness of the first sub-pixel within the first viewpoint period includes: reducing the number of lit sub-pixels by controlling the grayscale value, so that the first value equals the second value and the third value.

[0064] As another example, adjusting the brightness of the second and third sub-pixels within the first viewpoint period includes: reducing the number of lit sub-pixels and third sub-pixels by controlling the grayscale value, so that the first value equals the second value and the third value.

[0065] According to some embodiments, when the arrangement order of sub-pixels includes the arrangement order of a first sub-pixel, a second sub-pixel, a third sub-pixel, and a second first sub-pixel, the above-mentioned adjustment of the brightness of the first sub-pixel within the first viewpoint period according to the arrangement order of sub-pixels includes setting the grayscale value of the first or second first sub-pixel to 0.

[0066] Based on the above-mentioned color pattern removal method, when the number of first sub-pixels corresponding to the first viewpoint is greater than the number of second or third sub-pixels, by setting the grayscale value of the first or second sub-pixel to 0, the brightness values ​​of different types of sub-pixels can be made the same. In this way, the color patterns caused by the brightness differences of various sub-pixels can be reduced or even eliminated simply and efficiently, ensuring the color consistency and visual comfort of the display device screen.

[0067] For example, the arrangement order of the sub-pixels of the first viewpoint includes: the first red sub-pixel, the blue sub-pixel, the green sub-pixel, and the second red sub-pixel. Based on the above-mentioned color pattern removal method, the grayscale value of the first red sub-pixel can be set to 0, or the grayscale value of the second red sub-pixel can be set to 0, which can also be understood as turning off one of the red sub-pixels of the first viewpoint.

[0068] According to some embodiments, the arrangement order of sub-pixels includes: the arrangement order of a first sub-pixel, a second sub-pixel, a third sub-pixel, and a second first sub-pixel. The above-mentioned adjustment of the brightness of the first sub-pixel within the first viewpoint period according to the arrangement order of sub-pixels includes: assigning the grayscale value of the first sub-pixel corresponding to the image of the first viewpoint to the first first sub-pixel and the second first sub-pixel, so that the sum of the brightness values ​​of the first first sub-pixel and the second first sub-pixel is equal to the brightness value of the second sub-pixel or the third sub-pixel.

[0069] Based on the above-mentioned color pattern elimination method, when the number of first sub-pixels corresponding to the first viewpoint is greater than the number of second or third sub-pixels, by adjusting the distribution of the grayscale value of the first sub-pixel, the sum of the brightness values ​​of the first and second sub-pixels can be made equal to the brightness value of the second or third sub-pixel. In this way, color patterns caused by differences in brightness of various sub-pixels can be reduced or even eliminated more effectively, thereby improving the color consistency and uniformity of the displayed image and further improving the user's stereoscopic viewing experience.

[0070] For example, the arrangement order of the sub-pixels of the first viewpoint includes: the first red sub-pixel, the blue sub-pixel, the green sub-pixel, and the second red sub-pixel. Based on the above-mentioned color pattern removal method, the grayscale value of the red sub-pixel of the first viewpoint can be assigned to the first red sub-pixel and the second red sub-pixel according to a preset rule.

[0071] Optionally, the above preset rules can be designed with reference to the gamma curve (Gamma 2.x), where x is a positive integer.

[0072] According to some embodiments, in step S302, determining the arrangement order of the sub-pixels corresponding to the first viewpoint within the first viewpoint period based on the viewpoint mapping includes: determining the position coordinates of the sub-pixels corresponding to the first viewpoint based on the position of the sub-pixels corresponding to the first viewpoint in the viewpoint mapping and the tilt angle of the lens in the display panel; and determining the arrangement order of the sub-pixels corresponding to the first viewpoint based on the position coordinates of the sub-pixels corresponding to the first viewpoint.

[0073] Based on the above-mentioned color pattern elimination method, by using the position of the sub-pixel corresponding to the first viewpoint in the viewpoint mapping map and the tilt angle of the lens, the position coordinates of the sub-pixel corresponding to the first viewpoint can be accurately and efficiently determined, thereby determining the arrangement order of the sub-pixels corresponding to the first viewpoint, thus providing a premise and foundation for subsequent adjustment of the brightness of the sub-pixels within the first viewpoint period.

[0074] According to some embodiments, step S301 includes: obtaining lens parameters and the number of viewpoints in the display panel, wherein the lens parameters include: the relative positional relationship between pixels and lenses and the number of lens lines; and determining a viewpoint mapping map based on the lens parameters and the number of viewpoints.

[0075] Based on the above-mentioned color pattern elimination method, the viewpoint map can be accurately and efficiently determined according to the lens parameters and the number of viewpoints, thus providing a basis for subsequently determining the number and arrangement order of sub-pixels corresponding to the first viewpoint.

[0076] Figure 5 This is a flowchart illustrating another method for removing color patterns provided in this application embodiment. Method 500 can be a specific implementation of method 300, and method 500 can include steps S501 to S508.

[0077] S501, obtain the hardware parameters of the display device.

[0078] Optionally, the hardware parameters of the display device may include: lens parameters, pixel size, relative positional relationship between pixels and lenses, and lens line count, wherein the lens line count can be understood as the width of the lens in the horizontal direction.

[0079] S502, determine the viewpoint mapping based on the hardware parameters of the display device.

[0080] Alternatively, the viewpoint map can be determined using the following formula.

[0081]

[0082] Where n is the viewpoint, and (k, p) is the sub-pixel in the k-th row and p-th column. X is the total number of viewpoints, X is the number of lens lines, and β is the angle between the lens axis and the sub-pixel column.

[0083] For example, when β = 8.9°, X = 4.9, and the total number of viewpoints is 24, the following can be obtained based on the above formula: Figure 4 The viewpoint mapping diagram shown.

[0084] S503 calculates the viewpoint period and the distribution of sub-pixels within the viewpoint period.

[0085] The viewpoint period may include the first viewpoint period in method 300, and the distribution of sub-pixels in the viewpoint period includes the number or arrangement order of red sub-pixels, green sub-pixels and blue sub-pixels.

[0086] S504 determines whether the number of different types of sub-pixels is the same for each viewpoint within a viewpoint period.

[0087] For example, Figure 6 This is a schematic diagram of another viewpoint mapping provided in an embodiment of this application, such as... Figure 6 As shown, within the first viewpoint period (represented by the blue box), the red, blue, and green sub-pixels are cyclically distributed, and the number of red, blue, and green sub-pixels at viewpoints 1 to 12 is the same. Therefore, it can be considered that the display device does not exhibit viewpoint color pattern phenomenon. At this time, method 500 can be terminated; otherwise, step S505 can be performed.

[0088] S505, It has been determined that a viewpoint pattern has appeared on the display device.

[0089] S506a, determines that within a viewpoint period, the first sub-pixel is N more than other sub-pixels.

[0090] The aforementioned viewpoint period may include a first viewpoint period, the first sub-pixel may be a red sub-pixel, a green sub-pixel or a blue sub-pixel, and N is a positive integer.

[0091] For example, Figure 7 This is a schematic diagram of another viewpoint mapping diagram provided in an embodiment of this application. Figure 7 The viewpoint mapping is based on β=8.9°, X=4.9, and a total of 24 viewpoints, as shown below. Figure 7 As shown, within the first viewpoint period, red, blue, and green sub-pixels are cyclically distributed. However, the number of red, blue, and green sub-pixels corresponding to viewpoints 1 to 3 is different. That is, the number of red sub-pixels in viewpoint 1 is relatively large (compared to other sub-pixels in that viewpoint), the number of green sub-pixels in viewpoint 2 is relatively large, and the number of blue sub-pixels in viewpoint 3 is relatively large. At this time, it can be considered that the number of red sub-pixels in viewpoint 1, the number of green sub-pixels in viewpoint 2, and the number of blue sub-pixels in viewpoint 3 are N more than the number of other sub-pixels in the corresponding viewpoints. At this time, step S507a can be performed.

[0092] S506b determines that within a viewpoint period, the first sub-pixel is N fewer than other sub-pixels.

[0093] The aforementioned viewpoint period may include a first viewpoint period, the first sub-pixel may be a red sub-pixel, a green sub-pixel or a blue sub-pixel, and N is a positive integer.

[0094] For example, Figure 8 This is a schematic diagram of another viewpoint mapping provided in an embodiment of this application, such as... Figure 8 As shown, the viewpoint mapping diagram includes a first viewpoint period and a second viewpoint period. In the first viewpoint period, red, blue, and green sub-pixels are distributed cyclically. However, the number of red, blue, and green sub-pixels at viewpoints 1 to 3 is different. That is, the number of blue sub-pixels at viewpoint 1 is relatively small (compared to other sub-pixels at that viewpoint), the number of green sub-pixels at viewpoint 2 is relatively small, and the number of red sub-pixels at viewpoint 3 is relatively small. At this time, it can be considered that the number of blue sub-pixels at viewpoint 1, green sub-pixels at viewpoint 2, and red sub-pixels at viewpoint 3 is N fewer than the number of other sub-pixels at the corresponding viewpoints. At this time, step S507b can be performed.

[0095] S507a, determine the coordinates of the sub-pixel with a larger proportion of the viewpoint period in the display device.

[0096] For example, with Figure 7 Taking a lens tilted to the left (the lens setting direction is from the upper left to the lower right), this section details how to determine the coordinates and arrangement order of the sub-pixels of viewpoint 1. For example... Figure 7 As shown, the first row and first column represent the red sub-pixel 1R corresponding to viewpoint 1, denoted as (1,1). The coordinates of the other color sub-pixels of viewpoint 1 are denoted as (m,n). Then (m,n) and (1,1) satisfy the following relationship:

[0097] θ = arctan((m-1) / (n-1) / 3)

[0098] Where θ is the line tilt angle between (m,n) and (1,1), which can be determined by the tilt angle of the lens ±Q, where Q is the maximum deviation calculated based on the hardware parameters of the display device, and Q≤1°.

[0099] Using the above formula, the coordinates of other sub-pixels corresponding to viewpoint 1 can be calculated. For example, the coordinates of the green sub-pixel 1G (3,2) corresponding to viewpoint 1, the blue sub-pixel 1B (5,3) corresponding to viewpoint 1, the second red sub-pixel 1R (7,4) corresponding to viewpoint 1, and so on can be calculated.

[0100] Therefore, the order of appearance of the sub-pixels of viewpoint 1 within the first viewpoint period is: 1R_1, 1G, 1B, 1R_4. This means that within the first viewpoint period, there is one additional red sub-pixel, indicating a larger proportion of red sub-pixels. Similarly, the order of the sub-pixels corresponding to viewpoint 1 within each viewpoint period can be calculated. For example, it can be determined that there is one additional red sub-pixel in each viewpoint period. Here, 1R_1 can correspond to the first sub-pixel in method 300, and 1R_4 can correspond to the second sub-pixel in method 300.

[0101] Then, the coordinates of the green sub-pixel 5G of viewpoint 5 in the first row and second column, the blue sub-pixel 10B of viewpoint 10 in the first row and third column, and the sub-pixel corresponding to viewpoint X in the first row and nth column can be calculated sequentially. If the first row does not include the sub-pixels of all viewpoints (1 to 24), the above calculation process can be repeated for the sub-pixels of different viewpoints in the second row until the sub-pixels corresponding to all viewpoints are included.

[0102] Finally, the above process can be repeated for columns 1 to m in the viewpoint map, where m can be less than or equal to 10.

[0103] It should be noted that the above processing method is an example of lens tilting to the left. When the lens is tilted to the right (the lens setting direction is from the upper right to the lower left), the coordinates of the sub-pixels with a larger proportion in each viewpoint cycle can also be determined by referring to the above method.

[0104] S507b, determine the coordinates of the sub-pixel with a smaller proportion of the viewpoint period in the display device.

[0105] For example, referring to step S507a, the coordinates of the smaller sub-pixels within each viewpoint period can be calculated.

[0106] S508a, adjusts the brightness of the sub-pixels that account for a larger proportion within the viewpoint period.

[0107] In one possible implementation, following the example in step S507a, if the order of appearance of the sub-pixels of viewpoint 1 in the first viewpoint period is: 1R_1, 1G, 1B, 1R_4, and the order of appearance of the sub-pixels of viewpoint 2 is: 2G_1, 2B, 2R, 2G_4, then step S508 may include: setting the brightness value of 1R_1 or 1R_4 to 0, and setting the brightness value of 2G_1 or 2G_4 to 0. In other words, the adjusted brightness values ​​of 1R / 1G / 1B are 1 / 1 / 1, and the adjusted brightness values ​​of 2R / 2G / 2B are 1 / 1 / 1.

[0108] In one possible implementation, following the example in step S507a, if the order of appearance of the sub-pixels of viewpoint 1 in the first viewpoint period is: 1R_1, 1G, 1B, 1R_4, and the order of appearance of the sub-pixels of viewpoint 2 is: 2G_1, 2B, 2R, 2G_4, then step S508 may include: assigning the grayscale values ​​corresponding to the image of viewpoint 1 to 1R_1 and 1R_4 with reference to the Gamma2.x curve, such that the sum of the brightness values ​​of 1R_1 and 1R_4 is equal to 1G or 1B; and assigning the grayscale values ​​corresponding to the image of viewpoint 2 to 2G_1 and 2G_4 with reference to the Gamma2.x curve, such that the sum of the brightness values ​​of 2G_1 and 2G_4 is equal to 2B and 2R. In other words, the adjusted brightness values ​​of 1R / 1G / 1B are equal to 1 / 1 / 1, and the adjusted brightness values ​​of 2R / 2G / 2B are equal to 1 / 1 / 1.

[0109] Similarly, in other viewpoint cycles, the above two methods can be used to process sub-pixels that account for a large proportion.

[0110] S508b adjusts the brightness of the sub-pixel with a larger proportion of the viewpoint period.

[0111] For example, if the proportion of red sub-pixels in viewpoint 1 is relatively low during the first viewpoint period, the brightness of the extra green and blue sub-pixels can be set to 0, so that the adjusted brightness values ​​of 1R / 1G / 1B = 1 / 1 / 1. The brightness adjustment of sub-pixels can be achieved by adjusting the driving signal to control the grayscale value of the sub-pixels.

[0112] As another example, if the proportion of red sub-pixels in viewpoint 1 is relatively low during the first viewpoint period, the brightness value of 1R / 1G / 1B can be adjusted to 1 / 1 / 1 by adjusting the grayscale values ​​of the green and blue sub-pixels corresponding to viewpoint 1.

[0113] Similarly, sub-pixels of other viewpoints within the first viewpoint period, or viewpoints in other viewpoint periods, can also be processed in the same way as described above.

[0114] In this embodiment of the application, by adjusting the grayscale values ​​of sub-pixels at different viewpoints within the viewpoint period, the brightness values ​​of different types of sub-pixels corresponding to the viewpoints within the viewpoint period can be kept close, thereby reducing or even eliminating color patterns caused by differences in brightness of various sub-pixels, thus improving the naked-eye display effect of the display device.
