Pixel circuit and method of controlling the same, display panel and display device
The present disclosure discloses a pixel circuit and a method of controlling the same. The pixel circuit includes: a light-emitting control sub-circuit, configured to transmit a data voltage at a data signal terminal to a first node under control of a first control terminal; a driving sub-circuit, configured to transmit a first power supply voltage at a first power supply terminal VDD to a second node N2 under control of a voltage at the first node; a first sensing sub-circuit, configured to maintain a voltage at the second node to be at a fixed level under control of the first control terminal; a second sensing sub-circuit, configured to transmit the voltage at the second node to a first sensing signal terminal under control of a second control terminal, so that the first sensing signal terminal senses a voltage associated with a threshold voltage of the driving sub-circuit.
