Abstract: A pixel circuit includes a lighting element, a driving signal generating unit and a switching unit. The driving signal generating unit compares a data signal with a reference signal so as to generate a PWM driving signal. The status of the PWM driving signal is determined according to the comparing result of the data signal and the reference signal. The switching unit is electrically connected to a power source and the lighting element, and generates a driving current to drive the lighting element to emit light according to the PWM driving signal.
