摘要： A display panel includes a substrate and at least one pixel having a plurality of sub-pixels with a light transmission gap between two adjacent sub-pixels; the sub-pixel includes a metal circuit layer disposed on the substrate, a first electrode layer as a non-transparent anode disposed on the metal circuit layer, a light emission layer disposed on the first electrode layer, and a second electrode layer disposed on the light emission layer. Interference with effective imaging is reduced by adding the light shield layer in the each display unit of the display panel to reduce stray light entering the imaging component optimizing lossless rendering of the imaging quality of the under-screen imaging component, thereby balancing resolution and imaging quality.
