Abstract: A curved surface backlight module and a curved surface display device are provided. The backlight module includes a plurality of light-emitting units. The light-emitting units include reflector cups. The plurality of reflector cups include first reflector cups located in an edge partition and second reflector cups located in a central partition. The first reflector cups are asymmetric with respect to a first curved surface normal corresponding to a position at where the first reflector cups are located. A maximum brightness center of the first reflectors of the edge partition can be made to emit light parallel to a user's viewing direction, and brightness attenuation at an edge of a display device can be relieved.

Abstract: A driving method, a device, and a display terminal of a display panel are proposed. A charging order is sorted for each row of sub-pixels among the plurality of sub-pixels, so that total numbers of different color sub-pixels arranged at a target position are the same, wherein the target position comprises a first bit and a last bit in the charging order corresponding to each row of sub-pixels. When the sub-pixels in each row are scanned, each sub-pixel in a row is charged to drive the display panel according to the charging order corresponding to the row, thereby the display panel is driven.
