  • Publication number: 20230260472
    Abstract: The present disclosure discloses an array substrate, a liquid crystal display panel, and a display apparatus, which relate to the field of display technologies. The array substrate includes a first base and a plurality of photosensitive devices disposed on the first base. The photosensitive device can recognize fingerprints. In this way, the screen-to-body ratio of a display apparatus manufactured by using the array substrate is effectively increased. When an orthographic projection of the photosensitive device in the array substrate onto the first base at least partially overlaps with a white sub-pixel region, a pixel aperture ratio of the array substrate can be increased, so that a display apparatus that is subsequently manufactured by using the array substrate has a relatively good display effect.
