Abstract
A surface texture identification display device including a base substrate (10) and a contact plate overlapped with each other, the contact plate having a first surface configured to contact a textured surface, the first surface being located on a side of the contact plate facing away from the base substrate; and a plurality of pixel units located between the base substrate and the contact plate, wherein at least one of the pixel units includes a light sensing component on the base substrate, a light converging component located between light sensing component and the contact plate; a light shielding component located between light converging component and the light sensing component; wherein the light shielding component has a light transmission hole so that light passing through the contact plate and the light converging component passes through the light transmission hole to arrive at the light sensing component.
