摘要： A display panel has a display area including a light-transmissive area. The display panel includes a substrate, and a plurality of shielding patterns, a plurality of light-emitting layers and a plurality of cathodes that are disposed in the light-transmissive area and on the substrate. Orthogonal projections of the plurality of shielding patterns on the substrate are separated from each other. Each light-emitting layer and a respective cathode constitute a portion of a light-emitting device. The light-emitting device has an active light-emitting area. An orthogonal projection of the active light-emitting area on the substrate is located within an orthogonal projection of a cathode of the light-emitting device on the substrate. The plurality of cathode is located at a side of a respective shielding patterns away from the substrate. An orthogonal projection of the shielding pattern on the substrate covers the orthogonal projection of the cathode on the substrate.

摘要： The display substrate includes: a first electrode located in a first display region and a second electrode located in a second display region; a first light emitting layer located in the first display region and a second light emitting layer located in the second display region; and a third electrode located in the first display region and a fourth electrode located in the second display region. By optimizing patterned design of the third electrode, a first electrode wiring mode in the first display region is optimized, so that a display effect in the first display region is improved, glare interference is reduced, the transmittance of the first display region is optimized and improved, and a photographing effect of an under-screen camera configured in the first display region is ensured.
