摘要:
Provided is a pixel sensing circuit, including a signal generation sub-circuit, a reset sub-circuit, an amplification sub-circuit, and a read sub-circuit. The reset sub-circuit is configured to provide a signal of a first power supply line to a first node under control of a reset signal line. The signal generation sub-circuit is configured to detect a light signal and convert the detected light signal into an electrical signal. The amplification sub-circuit is configured to provide an amplified electrical signal to a second node according to a signal provided by a second power supply line and under control of the first node. The read sub-circuit is configured to output the amplified electrical signal to a signal read line under control of a scan signal line.
