Document Type and Number:
WIPO Patent Application WO/2022/225224
Kind Code:
A1
Abstract:
A display device according to the present invention comprises pixels and a sensor. The pixels comprise a light-emitting device and a pixel driving circuit. The pixel driving circuit receives a first scan signal and a second scan signal. The sensor comprises a photosensitive element and a sensor driving circuit. The sensor driving circuit comprises a reset transistor, an amplifier transistor, and an output transistor. The reset transistor receives a reset voltage and the first scan signal, and is connected to a first sensing node. The amplifier transistor receives a first driving voltage and is connected to first and second sensing nodes. The output transistor is connected to the second sensing node and a lead outline, and receives the second scan signal.
