Classification: CPC H  G | IPC G  H

Claim 13:
14. A method for manufacturing a display panel, the method comprising:
forming a display layer, the display layer being configured to display an image, the display layer having light-transmitting portions configured to transmit infrared light;
forming a photosensitive layer on a side of the display layer; and
forming an infrared mask on a side of the photosensitive layer proximate to the display layer, the infrared mask having hollowed-out regions configured to make the infrared mask have a preset pattern, and a region in the infrared mask except the hollowed-out regions being configured to prevent transmission of infrared light,
wherein the photosensitive layer is configured to receive infrared light passing through the hollowed-out regions in the infrared mask and the light-transmitting portions, and convert the infrared light into an image signal;
wherein the display panel further includes an encapsulation substrate, forming the photosensitive layer on a side of the display layer includes:
forming the photosensitive layer on the encapsulation substrate, the photosensitive layer including photosensitive layer (hiving circuits and a plurality of photosensitive elements, and the photosensitive layer driving circuits being coupled to the plurality of photosensitive elements; and
attaching the encapsulation substrate to the display layer, the photosensitive element being closer to the display layer than the encapsulation substrate, and an orthogonal projection of each photosensitive element on the display layer being within a region where a corresponding light-transmitting portion is located.
