Abstract:
The present disclosure provides a display substrate including a display area and a fingerprint recognition area. The display area includes a low-temperature polycrystalline oxide structure, an organic light-emitting layer, a cathode layer, and an anode layer that are sequentially stacked. The fingerprint recognition area includes an under-screen fingerprint recognition structure. The low-temperature polycrystalline oxide structure and the under-screen fingerprint recognition structure are disposed on a same layer. The under-screen fingerprint recognition structure includes the cathode layer and the organic light-emitting layer.
