Abstract:
A texture recognition device and a manufacturing method of the texture recognition device, a color filter substrate and a manufacturing method of the color filter substrate are provided. The texture recognition device has a touch side, and includes: a light source array, a light valve structure and an image sensor array. The light valve structure includes a first substrate, a second substrate, and a light adjustment layer, 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 in the light transmission state to form a first photosensitive light source. The second substrate of the light valve structure is closer to the touch side than the first substrate, and the image sensor array is on the second substrate.
