Claim 0:
1. A display panel, having a texture touch surface on a surface of the display panel, comprising:
a driving circuit layer, comprising a pixel driving circuit;
a light source array, on a side of the driving circuit layer close to the texture touch surface, comprising a plurality of light sources, which are driven by the pixel driving circuit of the driving circuit layer during operation;
an image sensor array, on a side of the driving circuit layer away from the texture touch surface, comprising a plurality of image sensors, wherein the plurality of image sensors are configured to receive light emitted from the plurality of light sources and reflected to the plurality of image sensors by a texture on a side of the texture touch surface away from the plurality of light sources, for texture collection; and
a black matrix layer, on a side of the light source array close to the texture touch surface, comprising a plurality of first light-transmitting openings and a plurality of second light-transmitting openings, wherein the plurality of first light-transmitting openings are configured to allow light, which is emitted from at least one of the plurality of light sources, emitted out from at least one of the plurality of second light-transmitting openings, and reflected by the texture, to pass through the plurality of first light-transmitting openings, to reach the plurality of image sensors;
wherein the driving circuit layer comprises a plurality of light-transmitting portions, and each of the plurality of first light-transmitting openings is arranged corresponding to at least one of the plurality of light-transmitting portions for transmitting light whose angle with the surface of the display panel is in a predetermined angle range, and in a first light-transmitting opening and a light-transmitting portion that are arranged correspondingly, a plane size of the first light-transmitting opening in a direction parallel to the surface of the display panel is smaller than a plane size of the light-transmitting portion in the direction parallel to the surface of the display panel.
