Abstract: A pixel circuit driving method of controlling an operation of a light-emitting element provided in a pixel of a display panel may comprise: applying pulse amplitude modulation (PAM) signals having a plurality of levels to a first terminal of a first transistor having a second terminal connected to a control terminal of a second transistor configured to drive the light-emitting element with a current according to a gray scale required for the light-emitting element; and applying a PAM signal of any one level selected from the PAM signals to the control terminal of the second transistor during each sub-frame time corresponding to a turn-on time of the first transistor controlled by a pulse width modulation (PWM) signal having a plurality of sub-frames in a single frame according to the gray scale.
