Texture recognition device and driving method of texture recognition device

A driving method of a texture recognition device, wherein the texture recognition device has a touch side and comprises:

• a light source array;
• an image sensor array 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;
• and
• a light valve structure which is on a side, close to the touch side, of the light source array;
• the driving method comprises:
• controlling a first region of the light valve structure to be in a light transmission state according to a control signal, so as to allow light emitted from the light source array to pass through the first region in the light transmission state to form a first photosensitive light source, wherein the first photosensitive light source forms a first imaging range on the image sensor array, and the first imaging range is used for imaging the texture.
