[0049] The specific embodiments of the present application have been shown through the above-described drawings, and will be described in more detail hereinafter. These drawings and the written description are not intended to restrict the scope of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0050] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same or similar components are denoted by the same or similar reference numerals throughout the drawings and the following description. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] Figure 1 A structure diagram of a display device is shown as Figure 1 As shown, the display device includes a timing controller (TCON) 400, a dimmer controller 300, a backlight unit 100 (BLU), and a liquid crystal display 200. The backlight unit 100 can include a plurality of backlight drivers 10 arranged in an array, and a plurality of light sources 30 connected to each backlight driver 10, which can be light-emitting diodes (LEDs) for example.

[0052] The timing controller 400 generates display data and local dimming data based on video data output from a video source (such as a graphics card or video processor), and sends the display data to the liquid crystal display panel 200 and the local dimming data to the backlight controller 300. The backlight controller 300 sends the local dimming data of each local dimming zone in the backlight unit to the corresponding backlight driver 10. The backlight driver 10 provides a backlight driving signal to the light source 30, which controls the brightness of the light source 30, thereby providing backlights of different brightness levels. The display data includes the brightness and color depth of each pixel on the liquid crystal display panel 200, and the liquid crystal display panel 200 displays images based on this data.

[0053] It should be noted that a local backlight area can be composed of one or more light sources, and 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 per zone corresponding to the local backlight area.

[0054] However, with the improvement of people's living standards and diversified needs, AM mini-LED (Active Matrix Mini Light-Emitting Diode) display devices are gradually becoming larger and more high-performance. To support larger display sizes and resolutions, display devices require more light sources to provide uniform backlighting. To achieve finer local dimming, the display area needs to be divided into more local backlight areas, thus the number of local backlight areas is gradually increasing, such as... Figure 2 As shown. Accordingly, the number of pixels on the liquid crystal display panel that matches a local backlight area gradually decreases, such as... Figure 3 As shown, the number of pixels corresponding to the local backlight area gradually decreases.

[0055] The applicant found that as the number of local backlight areas increases, it becomes more important to distribute the pixels on the LCD panel as evenly as possible across each local backlight area, for the following reasons:

[0056] 1. Fine-grained brightness control: Increasing the number of local backlight areas allows for finer brightness control. To fully utilize this fine-grained control, pixels need to be evenly distributed to ensure that each area can independently adjust its brightness, resulting in higher contrast and deeper blacks.

[0057] 2. Reduce halo effect: Halo effect is caused by the backlight of bright areas spilling into dark areas. When the number of local backlight areas is small, the area of the corresponding liquid crystal display panel for 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 uniform distribution of pixels can make the control of each backlight area more accurate.

[0058] 3. Improve image consistency: When the number of backlight areas increases, uniform pixel distribution helps maintain image consistency and uniformity. This can avoid some areas being too bright or too dark, ensuring consistent visual effects across the entire screen.

[0059] 4. Optimize energy efficiency: More backlight areas mean that the control of which areas need brightness enhancement and which areas can reduce brightness can be more precise. Uniformly distributed pixels make this control more effective, optimizing energy efficiency and reducing unnecessary energy consumption.

[0060] 5. Enhance dynamic range: By increasing local backlight areas and uniformly distributing 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.

[0061] Therefore, how to divide the pixels on the liquid crystal display panel as evenly as possible among the local backlight areas is an important problem.

[0062] To this end, the present application provides a pixel matching method, which determines the number of remaining pixels corresponding to the N-1th local backlight area in a target direction based on the number of final pixels corresponding to the N-1th local backlight area and the local backlight areas before it in the target direction on the backlight unit, then determines the number of preset pixels corresponding to the N-1th local backlight area in the target direction based on the number of remaining pixels and the number of remaining local backlight areas corresponding to the N-1th local backlight area, and determines the number of final pixels corresponding to the Nth local backlight area in the target direction based on the number of preset pixels, so that the number of final pixels corresponding to each local backlight area is similar, and the pixels on the liquid crystal display panel are divided as evenly as possible among the local backlight areas.

[0063] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0064] Figure 4 A flowchart of a pixel matching method provided in the present application is shown in FIG. 1, which includes the following steps. Figure 4

[0065] S101, determining a remaining pixel number corresponding to an N-1th local backlight region in a target direction according to a final pixel number corresponding to the N-1th local backlight region and previous local backlight regions in the target direction on a backlight unit.

[0066] wherein N is an integer greater than 1. The final pixel number corresponding to the first local backlight region in the target direction is obtained based on an initial pixel number corresponding to each local backlight region in the target direction.

[0067] In some examples, the initial pixel number corresponding to each local backlight region in the target direction is determined according to a total pixel number in the target direction on a liquid crystal display panel and a number of local backlight regions on the backlight unit, and the final pixel number corresponding to the first local backlight region in the target direction is determined according to the initial pixel number, so that the final pixel number corresponding to the first local backlight region in the target direction is close to the initial pixel number, so that the final pixel numbers corresponding to the local backlight regions can be similar in the subsequent steps, and the pixels on the liquid crystal display panel can be evenly divided into the local backlight regions as much as possible.

[0068] For example, the target direction can include a first direction and a second direction, the first direction and the second direction are two perpendicular directions, and the number of local backlight regions on the backlight unit refers to the number of all local backlight regions on the backlight unit.

[0069] Correspondingly, the final pixel number corresponding to the first local backlight region in the first direction can be determined according to a total pixel number in the first direction on the liquid crystal display panel and the number of local backlight regions on the backlight unit. The final pixel number corresponding to the first local backlight region in the second direction can also be determined according to a total pixel number in the second direction on the liquid crystal display panel and the number of local backlight regions on the backlight unit.

[0070] It should be noted that the initial pixel number corresponding to each local backlight region in the first direction is the same, and therefore the final pixel number corresponding to the first local backlight region in the first direction can be determined according to the initial pixel number corresponding to any local backlight region in the first direction.

[0071] ​The initial pixel number corresponding to each local backlight area in the second direction can also be determined according to the total pixel number in the second direction on the liquid crystal display panel and the number of local backlight areas on the backlight unit. It should be noted that the initial pixel number corresponding to each local backlight area in the second direction is the same, and therefore the final pixel number corresponding to the first local backlight area in the second direction can be determined according to the initial pixel number corresponding to any local backlight area in the second direction.

[0072] Specifically, the total pixel number in the first direction and the total pixel number in the second direction on the liquid crystal display panel can be obtained, and then a first ratio between the total pixel number in the first direction and the number of local backlight areas on the backlight unit can be calculated to obtain the initial pixel number corresponding to each local backlight area in the first direction. A second ratio between the total pixel number in the second direction and the number of local backlight areas on the backlight unit can also be calculated to obtain the initial pixel number corresponding to each local backlight area in the second direction.

[0073] For example, the pixel number of the liquid crystal display panel in the first direction is 3840, which can be a 4K resolution, and the number of local backlight areas on the backlight unit is 20, and therefore the initial pixel number corresponding to each local backlight area in the first direction is 3840 / 20 = 192.

[0074] For another example, the pixel number of the liquid crystal display panel in the first direction is 3840, and the number of local backlight areas on the backlight unit is 25, and therefore the initial pixel number corresponding to each local backlight area in the first direction is 3840 / 25 = 153.6.

[0075] In actual applications, the pixels on the liquid crystal display panel can be arranged in an array, the pixel number in the first direction can be the number of one row of pixels, and the pixel number in the second direction can be the number of one column of pixels. Conversely, the pixel number in the first direction can be the number of one column of pixels, and the pixel number in the second direction can be the number of one row of pixels.

[0076] In an embodiment, when the initial pixel number is an integer, the final pixel number corresponding to the first local backlight area in the target direction is determined as the initial pixel number corresponding to any local backlight area in the target direction, that is, the rounding operation can be omitted to simplify the operation process. When the initial pixel number includes a decimal, that is, the initial pixel number is not an integer, the initial pixel number corresponding to any local backlight area in the target direction is rounded to obtain the final pixel number corresponding to the first local backlight area in the target direction.

[0077] For example, after determining the initial pixel number corresponding to each local backlight region in the first direction, if the initial pixel number corresponding to the first direction is an integer, the final pixel number corresponding to the first direction of the first local backlight region is determined as the initial pixel number corresponding to the first direction, if the initial pixel number corresponding to the first direction is not an integer, the initial pixel number corresponding to the first direction is rounded to obtain the final pixel number corresponding to the first direction of the first local backlight region.

[0078] After determining the initial pixel number corresponding to each local backlight region in the second direction, if the initial pixel number corresponding to the second direction is an integer, the final pixel number corresponding to the second direction of the first local backlight region is determined as the initial pixel number corresponding to the second direction, if the initial pixel number corresponding to the second direction is not an integer, the initial pixel number corresponding to the second direction is rounded to obtain the final pixel number corresponding to the second direction of the first local backlight region.

[0079] In some examples, when the initial pixel number includes a decimal, the initial pixel number can be rounded in a rounding manner, or the initial pixel number can be rounded in an upward rounding manner, or the initial pixel number can be rounded in a downward rounding manner.

[0080] It can be understood that after determining the final pixel number of the first local backlight region in the target direction, the remaining pixel number corresponding to the first local backlight region in the target direction can be determined according to the final pixel number of the first local backlight region in the target direction. After determining the final pixel number of the second local backlight region in the target direction, the remaining pixel number of the second local backlight region in the target direction can be determined according to the final pixel number of the first local backlight region and the second local backlight region in the target direction.

[0081] In some examples, the local backlight regions on the backlight unit can be sorted, the identification number of each local backlight region can be determined, and the remaining pixel number corresponding to the N-1th local backlight region in the target direction can be determined according to the final pixel number of the N-1th local backlight region and all local backlight regions whose identification numbers are located before the identification number of the N-1th local backlight region. For example, the local backlight regions on the backlight unit can be sorted in ascending order, and the identification number of each local backlight region can be determined.

[0082] For example, the sequence number of the local backlight region is 1, which is determined as the first local backlight region, the sequence number of the local backlight region is 2, which is determined as the second local backlight region, and so on. The sequence number of the local backlight region is N, which is determined as the Nth local backlight region. If there is no other local backlight region, the Nth local backlight region is determined as the last local backlight region, and the number of local backlight regions on the backlight unit is N.

[0083] In some examples, the final pixel number corresponding to the Nth local backlight region in the target direction of the liquid crystal display panel can be determined according to the Nth local backlight region and all the local backlight regions located before the Nth local backlight region in the target direction of the liquid crystal display panel.

[0084] In this step, the pixel number in the target direction of the liquid crystal display panel is subtracted by the final pixel number corresponding to the Nth local backlight region and all the local backlight regions located before the Nth local backlight region in the target direction of the liquid crystal display panel, to obtain the remaining pixel number corresponding to the Nth local backlight region in the target direction.

[0085] For example, if N is 2, the pixel number in the target direction of the liquid crystal display panel is subtracted by the final pixel number corresponding to the first local backlight region in the target direction, to obtain the remaining pixel number corresponding to the first local backlight region in the target direction; if N is 3, the pixel number in the target direction of the liquid crystal display panel is subtracted by the final pixel number corresponding to the first local backlight region and the second local backlight region in the target direction, to obtain the remaining pixel number corresponding to the second local backlight region in the target direction.

[0086] In some examples, the remaining pixel number corresponding to the Nth local backlight region in the first direction can be determined according to the final pixel number corresponding to the Nth local backlight region and all the local backlight regions located before the Nth local backlight region in the first direction. The remaining pixel number corresponding to the Nth local backlight region in the second direction can also be determined according to the final pixel number corresponding to the Nth local backlight region and all the local backlight regions located before the Nth local backlight region in the second direction.

[0087] S102, determine the preset pixel number corresponding to the Nth local backlight region in the target direction based on the remaining pixel number and the number of remaining local backlight regions corresponding to the Nth local backlight region.

[0088] In this step, the preset pixel number corresponding to the Nth local backlight region in the target direction is determined according to the ratio of the remaining pixel number corresponding to the Nth local backlight region in the target direction to the number of remaining local backlight regions corresponding to the Nth local backlight region.

[0089] In this step, the preset pixel number corresponding to the Nth local backlight region in the target direction is determined according to the ratio of the remaining pixel number corresponding to the Nth local backlight region in the target direction to the number of remaining local backlight regions corresponding to the Nth local backlight region.

[0090] For example, the preset pixel number corresponding to the Nth local backlight region in the first direction can be determined according to the remaining pixel number corresponding to the N-1th local backlight region in the first direction and the number of remaining local backlight regions.

[0091] The preset pixel number corresponding to the Nth local backlight region in the second direction can be determined according to the remaining pixel number corresponding to the N-1th local backlight region in the second direction and the number of remaining local backlight regions.

[0092] S103, determining the final pixel number corresponding to the Nth local backlight region in the target direction based on the preset pixel number.

[0093] In the embodiments of the present application, the final pixel number corresponding to the Nth local backlight region in the target direction is determined according to the preset pixel number corresponding to the N-1th local backlight region in the target direction, so that the final pixel numbers corresponding to the local backlight regions in the target direction are similar, for example, the final pixel numbers corresponding to any two local backlight regions in the target direction differ by at most 1, so that the pixels on the liquid crystal display panel are as evenly divided as possible among the local backlight regions.

[0094] For example, the final pixel number corresponding to the Nth local backlight region in the first direction is determined according to the preset pixel number corresponding to the N-1th local backlight region in the first direction, and the final pixel number corresponding to the Nth local backlight region in the second direction is determined according to the preset pixel number corresponding to the N-1th local backlight region in the second direction.

[0095] In some embodiments, when the preset pixel number corresponding to the N-1th local backlight region in the target direction is an integer, the final pixel number corresponding to the Nth local backlight region is determined to be the preset pixel number corresponding to the N-1th local backlight region in the target direction, simplifying the operation. When the preset pixel number corresponding to the N-1th local backlight region in the target direction includes a decimal, the preset pixel number corresponding to the N-1th local backlight region in the target direction is rounded to obtain the final pixel number corresponding to the Nth local backlight region in the target direction, ensuring that the final pixel number can match the corresponding number of pixels.

[0096] In some examples, the initial pixel number and the preset pixel number can be rounded in a rounding manner, ensuring that the final pixel number corresponding to each local backlight region is an integer, so that the local backlight region can match the corresponding number of pixels.

[0097] Table 1

[0098]

[0099]

[0100] As shown in Table 1, taking the number of pixels in the first direction on the liquid crystal display panel as 3840 and the number of local backlight areas on the backlight unit as 25 as an example, the initial number of pixels is 3840 / 25 = 153.6.

[0101] The initial number of pixels is rounded to obtain the final number of pixels corresponding to the first local backlight area as 154; according to the final number of pixels corresponding to the first local backlight area in the first direction, the remaining number of pixels corresponding to the first local backlight area in the first direction is determined as 3840-154 = 3686; according to the remaining number of pixels corresponding to the first local backlight area in the first direction and the number of remaining local backlight areas, the preset number of pixels corresponding to the first local backlight area in the first direction is determined as 3686 / 24 = 153.583333; the preset number of pixels is rounded to obtain the final number of pixels corresponding to the second local backlight area in the first direction as 154.

[0102] The final number of pixels corresponding to the second local backlight area in the first direction is 154, and according to the final number of pixels corresponding to the second local backlight area in the first direction and the final number of pixels corresponding to the first local backlight area in the first direction, the remaining number of pixels corresponding to the second local backlight area in the first direction is determined as 3840-154-154 = 3532; according to the remaining number of pixels corresponding to the second local backlight area in the first direction and the number of remaining local backlight areas, the preset number of pixels corresponding to the second local backlight area in the first direction is determined as 3532 / 23 = 153.562174; the preset number of pixels is rounded to obtain the final number of pixels corresponding to the third local backlight area in the first direction as 154.

[0103] By analogy, the final number of pixels corresponding to the twenty-fourth local backlight area in the first direction is 154, and the remaining number of pixels corresponding to the twenty-fourth local backlight area in the first direction can be determined according to the final number of pixels corresponding to the first local backlight area to the twenty-fourth local backlight area in the first direction, that is, 153; according to the remaining number of pixels corresponding to the twenty-fourth local backlight area in the first direction and the number of remaining local backlight areas, the preset number of pixels corresponding to the twenty-fourth local backlight area in the first direction is determined as 153 / 1 = 153; at this time, no rounding is needed, and the final number of pixels corresponding to the twenty-fifth local backlight area in the first direction is determined as 153. Correspondingly, the remaining number of pixels corresponding to the twenty-fifth local backlight area in the first direction is 0, so that the final number of pixels corresponding to each local backlight area in the first direction is determined.

[0104] Accordingly, taking Table 2 as an example, each local backlight region can provide backlight for the pixels matching the final pixel number in the first direction, such as Figure 5 As shown, the first local backlight region provides backlight for 154 pixels in the first direction, the second local backlight region provides backlight for 154 pixels in the first direction, the twenty-fourth local backlight region provides backlight for 154 pixels in the first direction, and the twenty-fifth local backlight region provides backlight for 153 pixels in the first direction.

[0105] As can be seen from Table 1, through the above embodiments, the final pixel number corresponding to each local backlight region in the target direction is similar, for example, the final pixel number corresponding to any two local backlight regions in the target direction is at most 1 different, so that the pixels of the liquid crystal display panel in the target direction are as evenly divided as possible among the local backlight regions, and further, the pixels on the liquid crystal display panel are as evenly divided as possible among the local backlight regions.

[0106] In some examples, the initial pixel number and the preset pixel number can be rounded up in a rounding-up manner, so that the final pixel number corresponding to each local backlight region is an integer, so that the local backlight region can match a corresponding number of pixels.

[0107] Table 2

[0108]

[0109] As shown in Table 2, taking the number of pixels in the first direction on the liquid crystal display panel as 3840 and the number of local backlight regions on the backlight unit as 25 as an example, the initial pixel number is 3840 / 25 = 153.6.

[0110] The initial pixel number is rounded up in a rounding-up manner, and the final pixel number corresponding to the first local backlight region is 154. According to the final pixel number corresponding to the first local backlight region in the first direction, the number of remaining pixels corresponding to the first local backlight region in the first direction is determined to be 3840-154 = 3686. According to the number of remaining pixels corresponding to the first local backlight region in the first direction and the number of remaining local backlight regions, the preset pixel number corresponding to the first local backlight region in the first direction is determined to be 3686 / 24 = 153.583333. The preset pixel number is rounded up in a rounding-up manner, and the final pixel number corresponding to the second local backlight region in the first direction is 154.

[0111] The final pixel number corresponding to the second local backlight region in the first direction is 154. According to the final pixel number corresponding to the second local backlight region in the first direction and the final pixel number corresponding to the first local backlight region in the first direction, the remaining pixel number corresponding to the second local backlight region in the first direction is determined as 3840-154-154=3532. According to the remaining pixel number corresponding to the second local backlight region in the first direction and the number of remaining local backlight regions, the preset pixel number corresponding to the second local backlight region in the first direction is determined as 3532 / 23=153.562174. The preset pixel number is rounded in an upward rounding manner, and the final pixel number corresponding to the third local backlight region in the first direction is 154.

[0112] The final pixel number corresponding to the third local backlight region in the first direction is 154. According to the final pixel number corresponding to the first local backlight region to the third local backlight region in the first direction, the remaining pixel number corresponding to the third local backlight region in the first direction is determined as 3840-154-154-154=3378. According to the remaining pixel number corresponding to the third local backlight region in the first direction and the number of remaining local backlight regions, the preset pixel number corresponding to the third local backlight region in the first direction is determined as 3378 / 22=153.5454545. The preset pixel number is rounded in an upward rounding manner, and the final pixel number corresponding to the fourth local backlight region in the first direction is 153.

[0113] By analogy, the final pixel number corresponding to the twenty-fourth local backlight region in the first direction is 153. According to the final pixel number corresponding to the first local backlight region to the twenty-fourth local backlight region in the first direction, the remaining pixel number corresponding to the twenty-fourth local backlight region in the first direction is determined as 153. According to the remaining pixel number corresponding to the twenty-fourth local backlight region in the first direction and the number of remaining local backlight regions, the preset pixel number corresponding to the twenty-fourth local backlight region in the first direction is determined as 153 / 1=153. At this time, no rounding is needed, and the final pixel number corresponding to the twenty-fifth local backlight region in the first direction is determined as 153. Correspondingly, the remaining pixel number corresponding to the twenty-fifth local backlight region in the first direction is 0, so that the final pixel number corresponding to each local backlight region in the first direction is determined.

[0114] As shown in Table 2, by the above embodiments, the final pixel numbers corresponding to each local backlight area in the target direction are similar, for example, the final pixel numbers corresponding to any two local backlight areas in the target direction differ by at most 1, so that the pixels in the target direction of the liquid crystal display panel are as evenly as possible divided into each local backlight area, and further, the pixels on the liquid crystal display panel are as evenly as possible divided into each local backlight area.

[0116]

[0117]

[0118] As shown in Table 3, taking the pixel number in the first direction on the liquid crystal display panel as 3840 and the number of local backlight areas on the backlight unit as 25 as an example, the initial pixel number is 3840 / 25 = 153.6.

[0119] The initial pixel number is rounded in a downward rounding manner to obtain the final pixel number corresponding to the first local backlight area as 153; according to the final pixel number corresponding to the first local backlight area in the first direction, the remaining pixel number corresponding to the first local backlight area in the first direction is determined as 3840-153 = 3687; according to the remaining pixel number corresponding to the first local backlight area in the first direction and the number of remaining local backlight areas, the preset pixel number corresponding to the first local backlight area in the first direction is determined as 3687 / 24 = 153.625; the preset pixel number is rounded in a downward rounding manner to obtain the final pixel number corresponding to the second local backlight area in the first direction as 153.

[0120] The final pixel number corresponding to the second local backlight area in the first direction is 153, according to the final pixel number corresponding to the second local backlight area in the first direction and the final pixel number corresponding to the first local backlight area in the first direction, the remaining pixel number corresponding to the second local backlight area in the first direction is determined as 3840-153-153 = 3534; according to the remaining pixel number corresponding to the second local backlight area in the first direction and the number of remaining local backlight areas, the preset pixel number corresponding to the second local backlight area in the first direction is determined as 3534 / 23 = 153.6818182; the preset pixel number is rounded in a downward rounding manner to obtain the final pixel number corresponding to the third local backlight area in the first direction as 153.

[0121] Similarly, the final pixel number corresponding to the twenty-fourth partial backlight region in the first direction is 14, and the remaining pixel number corresponding to the twenty-fourth partial backlight region in the first direction can be determined according to the final pixel numbers corresponding to the first partial backlight region to the twenty-fourth partial backlight region in the first direction, which is 154; the preset pixel number corresponding to the twenty-fourth partial backlight region in the first direction can be determined according to the remaining pixel number corresponding to the twenty-fourth partial backlight region in the first direction and the number of the remaining partial backlight regions, which is 154 / 1=153; at this time, the final pixel number corresponding to the twenty-fifth partial backlight region in the first direction can be determined without rounding, which is 154. Correspondingly, the remaining pixel number corresponding to the twenty-fifth partial backlight region in the first direction is 0, so that the final pixel number corresponding to each partial backlight region in the first direction is determined.

[0122] As shown in Table 3, through the above embodiments, the final pixel numbers corresponding to each partial backlight region in the target direction are similar, for example, the final pixel numbers corresponding to any two partial backlight regions in the target direction differ by at most 1, so that the pixels in the target direction of the liquid crystal display panel are as evenly as possible divided into each partial backlight region, and further, the pixels on the liquid crystal display panel are as evenly as possible divided into each partial backlight region.

[0123] In other embodiments, if the initial pixel number and the preset pixel number are integers, rounding is not required, and correspondingly, the final pixel number corresponding to each partial backlight region is the same, that is, the initial pixel number.

[0124] Table 4

[0125]

[0126]

[0127] As shown in Table 4, the initial pixel number corresponding to each partial backlight region pair is 192, that is, the final pixel number corresponding to each partial backlight region is 192. Correspondingly, each partial backlight region can provide backlight for 192 pixels in the first direction, as shown in Table 4. Figure 6

[0130] ​In some embodiments, the target direction can include a first direction and a second direction, and thus the first sub-final pixel number corresponding to each local backlight region in the first direction and the second sub-final pixel number corresponding to each local backlight region in the second direction can be obtained based on steps S101-S103.

[0131] Then, the final pixel number corresponding to the Nth local backlight region can be determined according to the first final pixel number corresponding to the Nth local backlight region in the first direction and the second final pixel number corresponding to the Nth local backlight region in the second direction, and the pixels matched with the final pixel number corresponding to the Nth local backlight region are provided with backlight based on the Nth local backlight region.

[0132] For example, the first sub-final pixel number corresponding to the Nth local backlight region in the first direction and the second sub-final pixel number corresponding to the Nth local backlight region in the second direction are multiplied to obtain the final pixel number corresponding to the Nth local backlight region.

[0133] For example, the first sub-final pixel number corresponding to the first local backlight region in the first direction is 192, and the second sub-final pixel number corresponding to the first local backlight region in the second direction is 193, and thus the final pixel number corresponding to the first local backlight region is 192*193=37056, that is, the first local backlight region can provide backlight for 37056 pixels.

[0134] The pixel matching method provided by the embodiments of the present application can determine the final pixel number corresponding to the Nth local backlight region in the target direction according to the final pixel number corresponding to the N-1th local backlight region and the local backlight regions before the N-1th local backlight region in the target direction of the liquid crystal display panel, and then determine the preset pixel number corresponding to the N-1th local backlight region in the target direction based on the remaining pixel number and the number of the remaining local backlight regions corresponding to the N-1th local backlight region, so as to determine the final pixel number corresponding to the Nth local backlight region in the target direction according to the preset pixel number, thereby making the final pixel numbers corresponding to the local backlight regions similar and making the pixels on the liquid crystal display panel as evenly divided as possible among the local backlight regions.
