Abstract
A display panel has a light-exit side and a non-light-exit side opposite to the light-exit side. A direction pointing to the non-light-exit side from the light-exit side is a first direction. In the first direction, the display panel includes a coded aperture mask layer and an optical sensing layer. The coded aperture mask layer includes a plurality of first light-transmission portions and a plurality of first light-shielding portions. The coded aperture mask layer is configured to form at least one part of a coded aperture array. The optical sensing layer includes a plurality of optical sensors. The optical sensing layer is configured to receive texture recognition light passed through the coded aperture array and convert optical signals of the texture recognition light into electrical signals. The texture recognition light is light carrying information about a texture to be recognized.
