Abstract
A pixel circuit of a display panel includes a light emitting device, a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor and a first capacitor. The first transistor includes a drain terminal, a source terminal and a gate terminal. The second transistor is coupled to a data input terminal of the pixel circuit. The third transistor is coupled to the second transistor. The fourth transistor is coupled between the second transistor and the light emitting device. The fifth transistor is coupled between the drain terminal of the first transistor and the gate terminal of the first transistor. The sixth transistor is coupled between the second transistor and the drain terminal of the first transistor. The first capacitor is coupled between the third transistor and the gate terminal of the first transistor.
