Array substrate, display panel and display device capable of synchronizing image display and fingerprint identification
This disclosure provides an array substrate, a display panel and a display device. The array substrate comprises a substrate, a transistor and a photosensitive element above the substrate. The transistor comprises a gate and is used for controlling display of pixels. The photosensitive element comprises a light-transmissive electrode and a photosensitive layer, the light-transmissive electrode being used for allowing sensitive light rays reflected by a surface of a fingerprint pressed thereon to pass through and impinge on the photosensitive layer, and the light-transmissive electrode being connected to the gate. By connecting the light-transmissive electrode to the gate, the array substrate achieves synchronization of image display and fingerprint identification without individually providing a scan function for fingerprint identification, which greatly facilitates the actual applications requiring synchronization of image display and fingerprint identification.
