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： A display apparatus includes a display module and a camera module. The camera module is within a display area of the display module, and the camera module is over a side of the display module distal to a light-emitting surface of the display module. The display area of the display module includes a light-incident region positionally corresponding to a lens of the camera module, wherein the light-incident region is configured to allow lights from a side of the display apparatus proximal to the light-emitting surface of the display module to pass therethrough to thereby enter the lens of the camera module. The display apparatus further includes a backlight portion over a side of the display module distal to the light-emitting surface of the display module, and the camera module is arranged inside a mounting hole in the backlight portion.

摘要： A side-type backlight module includes a light guide plate and a reverse prism sheet that are stacked. The reverse prism sheet includes a first prism. A surface of the first prism proximate to the light guide plate includes a plurality of prism structures substantially parallel to each other. Each prism structure protrudes toward a direction approaching the light guide plate. A surface of the light guide plate proximate to the reverse prism sheet includes a plurality of strip-shaped microstructures substantially parallel to each other. Each strip-shaped microstructure protrudes toward a direction approaching the reverse prism sheet. An extending direction of the prism structure crosses an extending direction of the strip-shaped microstructure.
