Abstract:
A texture recognition device and a driving method of a texture recognition device (100) are provided. The texture recognition device has a touch side, and includes: a light source array, an image sensor array and a light valve structure; the image sensor array is configured to receive light emitted from the light source array and then reflected to the image sensor array by a texture for a texture image collection; the light valve structure is disposed on a side of the light source array close to a touch side and is configured to control a first region to be in a light transmission state in response to a control signal, so as to allow light emitted from the light source array to pass through the first region to form a first photosensitive light source in the light transmission state.
