Abstract
A pixel circuit includes a control switch module, a capacitor, a driving switch, and a light emitting element. The control switch module is enabled and disabled according to a scan signal. A first end of the capacitor can be electrically connected to the control switch module, and a second end of the capacitor can be electrically connected to a voltage level. The capacitor receives and stores a predetermined driving voltage when the control switch module is enabled. Area of the capacitor occupies more than 20% area of the pixel circuit. The driving switch can be electrically connected to the capacitor and a voltage source for controlling a driving current flowing through the driving switch according to the predetermined driving voltage stored in the capacitor. The light emitting element emits light according to the driving current flowing through the driving switch.
