Abstract:
1. A pixel circuit of a self-emitting display, being electrically coupled to a data line, a first power source line, a second power source line, a first control line, a second control line, and a third control line, the pixel circuit comprising: a first transistor, comprising a first terminal, a second terminal and a control terminal, the first terminal of the first transistor being electrically coupled to the data line, and the control terminal of the first transistor being electrically coupled to the first control line; a second transistor, comprising a first terminal, a second terminal and a control terminal, the first terminal of the second transistor being electrically coupled to the first power source line, and the control terminal of the second transistor being electrically coupled to the second control line; a third transistor, comprising a first terminal, a second terminal and a control terminal, the first terminal of the third transistor being directly and electrically coupled to the second terminal of the second transistor, and the control terminal of the third transistor being directly and electrically coupled to the second terminal of the first transistor; a fourth transistor, comprising a first terminal, a second terminal and a control terminal, the first terminal of the fourth transistor being directly and electrically coupled to the second terminal of the third transistor, and the control terminal of the fourth transistor being electrically coupled to the third control line; a first capacitor, comprising a first terminal directly and electrically coupled to the second terminal of the first transistor, a second terminal directly and electrically coupled to the first terminal of the third transistor; a second capacitor, comprising a first terminal directly and electrically coupled to the first terminal of the third transistor, and a second terminal directly and electrically coupled to the first power source line; and a light emitting element, comprising two terminals, one terminal directly and electrically coupled to the second terminal of the fourth transistor and the other terminal electrically coupled to the second power source line.
