Abstract
A pixel circuit includes a display unit, a driving unit, a reset unit, a data unit, and a storage unit. The display unit is electrically coupled to a first supply voltage source. The driving unit has one end electrically coupled to the display unit and has another end electrically coupled to a second supply voltage source. The driving unit charges the display unit. The reset unit is electrically coupled to the driving unit and the display unit, and provides a reset voltage to an operating node between the driving unit and the display unit. The data unit is electrically coupled to the driving unit and provides a data voltage to the driving unit. The storage unit stores a voltage difference between the operating node and a data node between the data unit and the driving unit.
