Abstract
A texture recognition method, a texture recognition device, and a display device. The texture recognition method includes: receiving a texture recognition signal by using a light blocking structure having a light transmission aperture; performing an amplification process on the texture recognition signal to obtain an amplified texture recognition signal; and detecting a valley line and a ridge line in a texture based on the amplified texture recognition signal.
