摘要： A texture recognition device and a display device are provided. The texture recognition device includes a backlight element, configured to provide first backlight; a light constraint element, configured to perform a light divergence angle constraint process on the first backlight to obtain second backlight with a divergence angle within a preset angle range, the second backlight being transmitted to a detection object; and a photosensitive element, configured to detect the second backlight reflected by a texture of the detection object to recognize a texture image of the texture of the detection object.

摘要： An array substrate includes a substrate, at least one first light-shielding layer disposed above the substrate, semiconductor retention layers disposed on a side of the at least one first light-shielding layer facing away from the substrate, and data lines disposed on a side of the plurality of semiconductor retention layers facing away from the at least one first light-shielding layer. One first light-shielding layer of the at least one first light-shielding layer is disposed between one semiconductor retention layer of the semiconductor retention layers and the substrate, and an orthographic projection of the first light-shielding layer on the substrate covers an orthographic projection of the semiconductor retention layer on the substrate. The data lines are in one-to-one correspondence with the semiconductor retention layers, and an orthographic projection of each data line on the substrate overlaps with an orthographic projection of a corresponding semiconductor retention layer on the substrate.

摘要： A display driving method includes: determining, by a timing controller, an actual grayscale value of a sub-pixel image in an X-th row and a Y-th column according to a preset grayscale value of a sub-pixel image in an (X−1)-th row and the Y-th column and a preset grayscale value of the sub-pixel image in the X-th row and the Y-th column of an image frame to be displayed. The image frame to be displayed includes J rows and Q columns of sub-pixel images. X is greater than or equal to 2, and is less than or equal to J. Y is greater than or equal to 1, and is less than or equal to Q, and X, Y, J, and Q are all integers.
