  • Publication number: 20220277584
    Abstract: 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.

  • Publication number: 20220244579
    Abstract: The present application discloses a display module, a preparation method thereof, and a display apparatus. In a non-display region of the display panel, the display panel and the optical adhesive have a first open pore and a second open pore penetrating through their thickness, respectively; and an orthographic projection of the first open pore falls in an orthographic projection of the second open pore on the cover plate. A light shading part in the light shading region has a third open pore surrounding the light transmitting region; and the light shading part includes a photochromic material in a light shading state, and an orthographic projection of the light shading part on the cover plate at least covers a region, which does not overlap with the orthographic projection of the first open pore on the cover plate, of the orthographic projection of the second open pore on the cover plate.
