Abstract
The disclosure discloses a pixel circuit, an electroluminescent display panel, driving methods thereof, and a display device. An initialization circuit, a photosensitive drive circuit, a photosensitive output circuit, and a photosensitive device are provided in the pixel circuit. Under the control of a second control signal terminal, an initialization signal provided by an initialization signal terminal is transmitted to a third node by the initialization circuit; under the control of a potential of the third node, the photosensitive drive circuit outputs a corresponding electrical signal; and under the control of a first gate signal terminal, the photosensitive output circuit transmits the electrical signal output by the photosensitive drive circuit to a reading signal terminal.
