[0048] Through the above-mentioned accompanying drawings, specific embodiments of the present application have been shown, and will be described in more detail hereinafter. These drawings and the written description are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by reference to specific embodiments. Detailed Description of the Embodiments

[0049] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0050] Figure 1 A schematic structural diagram of a display device is shown, as Figure 1 shown, the display device includes a Timing Controller (TCON) 400, a Dimmer Controller 300, a Backlight Unit (BLU) 100, and a Liquid Crystal Display 200. Among them, the backlight unit 100 may include a plurality of backlight drivers 10 arranged in an array, and a plurality of light sources 30 connected to each backlight driver 10. The light source 30 may be, for example, a Light-emitting Diode (LED).

[0051] The timing controller 400 is configured to generate display data and local dimmer data according to video data output by a video source (such as a graphics card, a video processor), and send the display data to the liquid crystal display panel 200 and the local dimmer data to the backlight controller 300. The backlight controller 300 is configured to send the local dimmer data of each local backlight area in the backlight unit to the corresponding backlight driver 10. The backlight driver 10 provides a backlight driving signal to the light source 30, and the backlight driving signal can control the light emitting brightness of the light source 30, thereby providing backlights with different brightnesses. The display data includes the brightness values and color depths of each pixel on the liquid crystal display panel 200, and the liquid crystal display panel 200 displays an image based on the display data.

[0052] It should be noted that a local backlight area can be composed of one or several light sources. The number of pixels on the liquid crystal display panel that match the local dimming area can be n×m. These n×m pixels are called the number of pixels corresponding to the local backlight area (Pixel Per Zone).

[0053] However, with the improvement of people's living quality and diverse demands, AM mini-LED (Active Matrix mini Light-emitting Diode) display devices are gradually becoming larger and more high-performance. To support a larger display size and resolution, the display device requires more light sources to provide uniform backlight. To achieve finer local dimming, the display area needs to be divided into more local backlight areas, and the number of local backlight areas gradually increases, as Figure 2 shown. Correspondingly, the number of pixels on the liquid crystal display panel that match a local backlight area gradually decreases, as Figure 3 shown, that is, the number of pixels corresponding to the local backlight area gradually decreases.

[0054] The applicant found that as the number of local backlight areas increases, it becomes more important to distribute the pixels on the liquid crystal display panel as evenly as possible among each local backlight area. The reasons are as follows:

[0055] 1. Fine brightness control: Increasing the number of local backlight areas can achieve finer brightness control. To make full use of this fine control, the pixels need to be evenly distributed to ensure that each area can independently adjust its brightness, thereby achieving higher contrast and deeper black levels.

[0056] 2. Reducing the halo effect: The halo effect is caused by the backlight of the bright area spilling over into the dark area. When the number of local backlight areas is small, the area of the liquid crystal display panel corresponding to each area is large, and the backlight of the bright area is more likely to affect the backlight of the dark area. When the number of local backlight areas is large, the brightness of each area can be more accurately controlled, reducing the halo effect, and the evenly distributed pixels can make the control of each backlight area more precise.

[0057] 3. Improving image consistency: When the number of backlight areas increases, the uniform pixel distribution helps to maintain the consistency and uniformity of the image. This can avoid some areas being too bright or too dark, ensuring a consistent visual effect across the entire screen.

[0058] 4. Optimizing energy efficiency: More backlight areas mean that it is possible to more finely control which areas need to increase brightness and which areas can reduce brightness. The evenly distributed pixels make this control more effective, thereby optimizing energy efficiency and reducing unnecessary energy consumption.

[0059] 5. Enhance the dynamic range: By increasing the local backlight areas and evenly distributing the pixels, the display can better support High Dynamic Range (HDR). This means that very bright and very dark details can be displayed simultaneously in the same picture, enhancing the visual experience.

[0060] Therefore, how to divide the pixels on the liquid crystal display panel as evenly as possible among the local backlight areas is a relatively important issue.

[0061] For this purpose, this application provides a pixel matching method. After obtaining the preset number of pixels corresponding to each local backlight area in the target direction, the preset number of pixels is rounded to obtain the target number of pixels. Then, the target number of pixels corresponding to two adjacent local backlight areas in the target direction is subtracted to obtain the final number of pixels corresponding to the latter local backlight area in the target direction among two adjacent local backlight areas. Thus, the final number of pixels corresponding to each local backlight area can be made similar, and the pixels on the liquid crystal display panel can be divided as evenly as possible among the local backlight areas.

[0062] The following uses specific embodiments to elaborate in detail on the technical solution of this application and how the technical solution of this application solves the above technical problems. These several specific embodiments below can be combined with each other, and for the same or similar concepts or processes, they may not be repeated in some embodiments. The embodiments of this application will be described below in conjunction with the accompanying drawings.

[0063] Figure 4 is a schematic flowchart of the pixel matching method provided by this application, as Figure 4 shown, this method includes:

[0064] S101. Obtain the initial number of pixels corresponding to each local backlight area on the backlight unit in the target direction of the liquid crystal display panel.

[0065] Exemplarily, the backlight unit includes multiple local backlight areas, and each local backlight area corresponds to a group of pixels on the liquid crystal display panel.

[0066] In some embodiments, the target direction may include a first direction and a second direction, and the first direction and the second direction are two mutually perpendicular directions. Correspondingly, the initial number of pixels corresponding to each local backlight area on the backlight unit in the first direction of the liquid crystal display panel can be obtained, as well as the initial number of pixels corresponding to each local backlight area in the second direction of the liquid crystal display panel.

[0067] In some examples, obtain the total number of pixels in the first direction of the liquid crystal display panel, the total number of pixels in the second direction of the liquid crystal display panel, and the number of local backlight regions on the backlight unit. The number of local backlight regions on the backlight unit refers to the quantity of all local backlight regions on the backlight unit.

[0068] Correspondingly, according to the total number of pixels in the first direction on the liquid crystal display panel and the number of local backlight regions on the backlight unit, the initial number of pixels corresponding to each local backlight region in the first direction can be determined. Also, according to the total number of pixels in the second direction on the liquid crystal display panel and the number of local backlight regions on the backlight unit, the initial number of pixels corresponding to each local backlight region in the second direction can be determined.

[0069] It should be noted that the initial number of pixels corresponding to each local backlight region in the first direction is the same, and the initial number of pixels corresponding to each local backlight region in the second direction is the same.

[0070] For example, after obtaining the total number of pixels in the first direction and the total number of pixels in the second direction on the liquid crystal display panel, the first ratio between the total number of pixels in the first direction and the number of local backlight regions on the backlight unit can be calculated, so as to obtain the initial number of pixels of each local backlight region in the first direction. Also, the second ratio between the total number of pixels in the second direction and the number of local backlight regions on the backlight unit can be calculated, so as to obtain the initial number of pixels of each local backlight region in the second direction.

[0071] For example, if the total number of pixels in the first direction of the liquid crystal display panel is 3840, the resolution can be 4K at this time, and the number of local backlight regions on the backlight unit is 20, then the initial number of pixels corresponding to each local backlight region in the first direction is 3840 / 20 = 192.

[0072] Another example, if the total number of pixels in the first direction of the liquid crystal display panel is 3840 and the number of local backlight regions on the backlight unit is 25, then the initial number of pixels corresponding to each local backlight region in the first direction is 3840 / 25 = 153.6.

[0073] In practical applications, the pixels on the liquid crystal display panel can be arranged in an array. The number of pixels in the first direction can be the number of pixels in a row, and the number of pixels in the second direction can be the number of pixels in a column. Conversely, the number of pixels in the first direction can be the number of pixels in a column, and the number of pixels in the second direction can be the number of pixels in a row.

[0074] S102. Based on the initial number of pixels, determine the preset number of pixels corresponding to each local backlight region in the target direction, and round the preset number of pixels to obtain the target number of pixels corresponding to each local backlight region in the target direction.

[0075] Exemplarily, each local backlight region has a corresponding identification number. For the target local backlight region, the preset number of pixels corresponding thereto in the target direction may include the initial number of pixels corresponding to the target local backlight region in the target direction, and the initial number of pixels corresponding to all the local backlight regions whose identification numbers are before the identification number of the target local backlight region. Wherein, the target local backlight region may be any local backlight region.

[0076] For example, if the identification number of the target local backlight region is 3, the preset number of pixels corresponding to the target local backlight region includes the initial number of pixels corresponding to three local backlight regions; if the identification number of the target local backlight region is 2, the preset number of pixels corresponding to the target local backlight region includes the initial number of pixels corresponding to two local backlight regions.

[0077] In some embodiments, each local backlight region on the backlight unit is sorted to obtain the identification number of each local backlight region, and then the product of the identification number and the initial number of pixels of each local backlight region is calculated to obtain the preset number of pixels corresponding to each local backlight region in the target direction. For example, each local backlight region on the backlight unit may be sorted in ascending order to obtain the serial number of each local backlight region.

[0078] Exemplarily, the initial number of pixels corresponding to each local backlight region in the first direction may be multiplied by the corresponding identification number to obtain the preset number of pixels corresponding to each local backlight region in the first direction. It is also possible to multiply the initial number of pixels corresponding to each local backlight region in the second direction by the corresponding identification number to obtain the preset number of pixels corresponding to each local backlight region in the second direction.

[0079] Table 1

[0080]

[0081]

[0082] As shown in Table 1, taking the initial number of pixels corresponding to the local backlight region in the first direction as 153.6 as an example. If the identification number of the local backlight region is 1, the preset number of pixels corresponding to the local backlight region in the first direction is 153.6×1 = 153.6; if the identification number of the local backlight region is 2, the preset number of pixels corresponding to the local backlight region in the first direction is 153.6×2 = 307.2; and so on. If the identification number of the local backlight region is 25, the preset number of pixels corresponding to the local backlight region in the first direction is 153.6×25 = 3840.

[0083] In some other embodiments, the total number of pixels in the target direction of the liquid crystal display panel can be successively subtracted by the initial number of pixels. Each time the initial number of pixels is subtracted, a preset number of pixels corresponding to a local backlight area in the target direction can be obtained, thereby obtaining the preset number of pixels corresponding to each local backlight area in the target direction.

[0084] In this step, after obtaining the preset number of pixels corresponding to each local backlight area in the target direction, since the preset number of pixels is the sum of multiple initial numbers of pixels, and the initial number of pixels may include decimals, that is, the initial number of pixels is not an integer, so the preset number of pixels corresponding to any local backlight area in the target direction may include decimals. However, when performing the matching operation between the local backlight area and the pixels, it is impossible to match the pixels corresponding to the decimals for the local backlight area. Therefore, the preset number of pixels corresponding to each local backlight area in the target direction is rounded to obtain the target number of pixels corresponding to each local backlight area in the target direction.

[0085] Exemplarily, the preset number of pixels corresponding to each local backlight area in the first direction can be rounded to obtain the target number of pixels corresponding to each local backlight area in the first direction.

[0086] It is also possible to obtain the preset number of pixels corresponding to each local backlight area in the second direction, round the preset number of pixels corresponding to each local backlight area in the second direction, and obtain the target number of pixels corresponding to each local backlight area in the second direction.

[0087] In some embodiments, when the preset number of pixels is an integer, the target number of pixels is the preset number of pixels, and the rounding operation can be omitted to simplify the operation process; when the preset number of pixels includes decimals, that is, when the preset number of pixels is not an integer, the preset number of pixels is rounded to obtain the target number of pixels.

[0088] In some embodiments, the preset number of pixels can be rounded according to the rounding method to obtain the target number of pixels.

[0089] Table 2

[0090]

[0091]

[0092] As shown in Table 2, when the preset number of pixels is 153.6, the target number of pixels obtained after rounding is 154; when the preset number of pixels is 307.2, the target number of pixels after rounding is 307.

[0093] Correspondingly, as Figure 5As shown, the first local backlight area provides backlight for 154 pixels in the first direction, the second local backlight area provides backlight for 153 pixels in the first direction, the twenty-fourth local backlight area provides backlight for 153 pixels in the first direction, and the twenty-fifth local backlight area provides backlight for 154 pixels in the first direction.

[0094] In some embodiments, the preset number of pixels is rounded up to obtain the target number of pixels.

[0095] Table 3

[0096]

[0097]

[0098] As shown in Table 3, the preset number of pixels is 153.6, and the target number of pixels obtained after rounding up is 154; the preset number of pixels is 307.2, and the target number of pixels obtained after rounding up is 308.

[0099] In some embodiments, the preset number of pixels is rounded down to obtain the target number of pixels.

[0100] Table 4

[0101]

[0102]

[0103] As shown in Table 4, the preset number of pixels is 153.6, and the target number of pixels obtained after rounding down is 153; the preset number of pixels is 307.2, and the target number of pixels obtained after rounding down is 307.

[0104] S103. Obtain the final number of pixels corresponding to the Nth local backlight area in the target direction according to the difference between the target number of pixels corresponding to the (N - 1)th local backlight area and the Nth local backlight area in the target direction.

[0105] Wherein, N is an integer greater than 0.

[0106] Exemplarily, according to the difference between the target number of pixels corresponding to two adjacent local backlight areas in the target direction, obtain the final number of pixels corresponding to the local backlight area with a later identification number among the two adjacent local backlight areas in the target direction.

[0107] Specifically, subtract the target number of pixels corresponding to the (N - 1)th local backlight area in the target direction from the target number of pixels corresponding to the Nth local backlight area in the target direction to obtain the final number of pixels corresponding to the Nth local backlight area in the target direction.

[0108] Exemplarily, subtract the number of target pixels corresponding to the Nth local backlight area in the first direction from the number of target pixels corresponding to the (N - 1)th local backlight area in the first direction to obtain the final number of pixels corresponding to the Nth local backlight area in the first direction. Subtract the number of target pixels corresponding to the Nth local backlight area in the second direction from the number of target pixels corresponding to the (N - 1)th local backlight area in the second direction to obtain the final number of pixels corresponding to the Nth local backlight area in the second direction.

[0109] It should be noted that the final number of pixels is close to the initial number of pixels, and it can ensure that the final number of pixels corresponding to each local backlight area in the target direction is close, so that the pixels in the target direction on the liquid crystal display panel can uniformly correspond to each local backlight area.

[0110] For example, as shown in Table 2, taking the first direction as an example, when N = 1, the final number of pixels corresponding to the first local backlight area is 154; when N = 2, subtract the number of target pixels corresponding to the first local backlight area from the number of target pixels corresponding to the second local backlight area to obtain the final number of pixels corresponding to the second local backlight area as 153; when N = 25, subtract the number of target pixels corresponding to the 24th local backlight area from the number of target pixels corresponding to the 25th local backlight area to obtain the final number of pixels corresponding to the 25th local backlight area as 154.

[0111] As shown in Table 3, taking the first direction as an example, when N = 2, subtract the number of target pixels corresponding to the first local backlight area from the number of target pixels corresponding to the second local backlight area to obtain the final number of pixels corresponding to the second local backlight area as 154; when N = 25, subtract the number of target pixels corresponding to the 24th local backlight area from the number of target pixels corresponding to the 25th local backlight area to obtain the final number of pixels corresponding to the 25th local backlight area as 153.

[0112] As shown in Table 4, taking the first direction as an example, when N = 2, subtract the number of target pixels corresponding to the first local backlight area from the number of target pixels corresponding to the second local backlight area to obtain the final number of pixels corresponding to the second local backlight area as 154; when N = 25, subtract the number of target pixels corresponding to the 24th local backlight area from the number of target pixels corresponding to the 25th local backlight area to obtain the final number of pixels corresponding to the 25th local backlight area as 154.

[0113] Moreover, as shown in Tables 2 - 4, the final number of pixels corresponding to each local backlight area obtained by the method according to the embodiments of the present application in the target direction is close, with a maximum difference of 1, so that the pixels in the target direction on the liquid crystal display panel can uniformly correspond to each local backlight area.

[0114] In other embodiments, if the initial number of pixels is an integer, there is no need to round the preset number of pixels. Correspondingly, the final number of pixels corresponding to each local backlight area is the same, that is, the initial number of pixels.

[0115] Table 5

[0116]

[0117]

[0118] As shown in Table 5, the initial number of pixels for each pair of local backlight areas is 192, that is, the final number of pixels corresponding to each local backlight area is 192.

[0119] Correspondingly, each local backlight area can provide backlight for the pixels with the final number of pixels corresponding to the target direction. Taking Table 5 as an example, each local backlight area can provide backlight for 192 pixels in the first direction, as Figure 6 shown.

[0120] S104. Based on the Nth local backlight area, provide backlight for the pixels with the final number of pixels.

[0121] In some embodiments, the target direction may include at least one of the first direction and the second direction. Therefore, the first sub-final number of pixels corresponding to each local backlight area in the first direction and the second sub-final number of pixels corresponding to each local backlight area in the second direction can be obtained based on steps S101 - S103.

[0122] Correspondingly, the final number of pixels corresponding to the Nth local backlight area can be determined according to the first sub-final number of pixels corresponding to the Nth local backlight area in the first direction and the second sub-final number of pixels corresponding to the Nth local backlight area in the second direction.

[0123] For example, multiplying the first sub-final number of pixels and the second sub-final number of pixels can obtain the final number of pixels. Correspondingly, based on each local backlight area, backlight can be provided for the final number of pixels corresponding to each local backlight area.

[0124] For example, if the first sub-final number of pixels corresponding to the Nth local backlight area in the first direction is 192 and the second sub-final number of pixels corresponding to the Nth local backlight area in the second direction is 193, then the final number of pixels corresponding to the Nth local backlight area is 192×193 = 37056, that is, the Nth local backlight area can provide backlight for 37056 pixels.

[0125] The pixel matching method provided by the embodiments of the present application obtains the initial number of pixels corresponding to each local backlight area on the backlight unit in the target direction of the liquid crystal display panel. Based on the initial number of pixels, it determines the preset number of pixels corresponding to each local backlight area in the target direction, and rounds the preset number of pixels to obtain the target number of pixels corresponding to each local backlight area in the target direction. Then, according to the difference between the target number of pixels corresponding to the (N - 1)-th local backlight area and the N-th local backlight area in the target direction, it obtains the final number of pixels corresponding to the N-th local backlight area in the target direction, so that the final number of pixels corresponding to each local backlight area can be made similar, and the pixels on the liquid crystal display panel can be divided as evenly as possible among each local backlight area.
