Abstract
A detection circuit includes a photosensitive device, a first storage sub-circuit, a second storage sub-circuit group, and an output control sub-circuit. The photosensitive device is coupled to a device voltage terminal and an output node. The first storage sub-circuit is coupled to the output node and a first voltage terminal. The second storage sub-circuit group is coupled to the output node, a second voltage terminal group and a second control signal terminal group. The output control sub-circuit is coupled to a signal receiving terminal, a first control signal terminal, and the output node.
