Abstract
Disclosed is a display device having a pixel electrode and a pixel driving transistor. The display device comprises a capacitor, a gate voltage control transistor and a source driving circuit. The capacitor, coupled to the gate of the pixel driving transistor, holds the applied voltage to the aforesaid gate. The gate voltage control transistor has a drain coupled to a connection point between the gate of the pixel driving transistor and the capacitor, a source coupled to the source bus line and a gate coupled to the gate line, for controlling the applied voltage of the capacitor. The source driving circuit utilizes the adjacent source bus lines to alternately switch the voltage held by the capacitor among several different high voltages and several different low voltages to drive the source.
