Abstract
A display panel and a pixel circuit of the display panel are provided. The pixel circuit includes a driving transistor and a light-emitting time length modulator. The driving transistor has a control terminal receiving a pulse width control signal and an amplitude control signal, and the driving transistor generates a driving signal. In a first time period, the light-emitting time length modulator modulates a time length of a plurality of second time periods for providing the driving signal to a light-emitting device according to a light-emitting time control signal.
