Abstract:
A display device is proposed, the display device including a display panel and a driving circuit, and pixels included in the display panel includes a driving transistor, a light emitting element, a capacitor, and first to sixth switching transistors T1 to T6. T1 senses threshold voltage of the driving transistor, the capacitor stores data voltage and a threshold voltage in both electrodes, T2 applies data voltage to the capacitor, T3 initializes the storage capacitor to reference voltage, and T4 initialize the light emitting element to reference voltage, T5 controls current flow between the driving transistor and the light emitting element, and T6 connects both electrodes of the capacitor. The driving circuit divides one frame into an initialization period, a program period, and a light emission period to drive a pixel, and stops light emission of the light emitting device and make equal voltage across the capacitor, in the initialization period.
