Abstract
A pixel circuit includes a light-emitting diode (LED), a first driving transistor, a second driving transistor, a pulse amplitude modulation circuit, and a pulse width modulation circuit. The first driving transistor has a first terminal, a control terminal receiving an amplitude control signal, and a second terminal. The second driving transistor has a first terminal coupled to the second terminal of the first driving transistor, a control terminal receiving a width control signal, and a second terminal coupled to an anode of the LED. A channel polarity of the second driving transistor is different from that of the first driving transistor. The pulse amplitude modulation circuit provides the amplitude control signal based on an emission signal and an amplitude data voltage. The pulse width modulation circuit provides the width control signal based on the emission signal, a swing signal, and a width data voltage.
