In some embodiments, the display panel has a plurality of sub-pixel regions, each display partition corresponding to at least one sub-pixel region, or a plurality of display partitions corresponding to one sub-pixel region.
As shown in fig. 2a and 2b, when one display partition 11 corresponds to a plurality of sub-pixel regions 12, one image sensor is used to capture the display pictures displayed by the plurality of sub-pixel regions 12, and the display brightness of each display partition 11 may be the average brightness, the maximum brightness, the minimum brightness, or the like of the plurality of sub-pixel regions 12 corresponding to the display partition 11.

Since the display gray scale of each display section 11 is obtained from the actual display luminance of each display section 11, the display gray scale of each display section 11 is the actual display gray scale corresponding to the actual display luminance when the display panel 10 displays a screen.
As shown in fig. 5, the abscissa represents the gray scale and the ordinate represents the luminance. The gray scale can be divided into 10 equal parts, and if the value range of the gray scale is 0-255, the gray scale of each equal part is 25.5; the brightness is divided into 10 equal parts, and if the value range of the brightness is 0-1000 nit (nit), the brightness of each equal part is 100 nit.

By adjusting the data signal Vdata received by the thin film transistor 17 corresponding to the first display sub-region, the electric potential of the pixel electrode 15 corresponding to the first display sub-region is changed, and thus the voltage between the common electrode 16 and the pixel electrodes 15 is changed, the electric field between the common electrode 16 and the pixel electrodes 15 is changed, and under the action of the electric field, the deflection angle of the liquid crystal 18 corresponding to the first display sub-region is changed, and thus the display brightness of the sub-pixel region 12 corresponding to the first display sub-region is changed.
As shown in fig. 7a, the pixel electrode 15 may be disposed on the array substrate, and the common electrode 16 may be disposed on the opposite-to-cartridge substrate; alternatively, as shown in fig. 7b, the pixel electrode 15 and the common electrode 16 may be both disposed on the array substrate. In addition, the liquid crystal display panel may further include a color filter layer, a black matrix, an alignment layer, a spacer, and the like. The color filter layer and the black matrix can be arranged on the array substrate and can also be arranged on the box aligning substrate; the alignment layers are respectively arranged on the array substrate and the box substrate, and the liquid crystals 18 can be arranged according to the alignment direction of the alignment layers; the spacer is arranged between the array substrate and the box aligning substrate and used for supporting the array substrate and the box aligning substrate after the alignment.

In some embodiments, values of the display gray scale and the input gray scale of the second display partition and the input gray scale of the sub-pixel region before adjustment are not limited, and the values of the display gray scale and the input gray scale of the second display partition and the input gray scale of the sub-pixel region 12 before adjustment are related to the image displayed by the display panel 10.
For example, taking the preset range of 0 to 20, the input gray scale of the second display sub-area is 200, the display gray scale of the second display sub-area is 170, and the input gray scale of one sub-pixel area 12 corresponding to the first display sub-area before adjustment is 150 as an example, the dark spot appears in the second display sub-area, the display brightness of the sub-pixel area 12 corresponding to the first display sub-area can be reduced, and the input gray scale of the sub-pixel area 12 after adjustment is 150
Taking the preset range of 0-20, the input gray scale of the second display sub-area being 200, the display gray scale being 230, and the input gray scale of one sub-pixel area 12 corresponding to the first display sub-area before adjustment being 150 as an example, the second display sub-area appears bright spots, which can brighten the display brightness of the sub-pixel area 12 of the first display sub-area, and the input gray scale of the sub-pixel area 12 after adjustment being 150

Of course, when adjusting the input gray scale of the sub-pixel region 12 corresponding to the first display sub-region, the color coordinate and/or the color temperature of the sub-pixel region 12 may be used as a reference.
