Abstract

The present disclosure provides a display device including a light emitting diode and a driving module. The driving module drives the light emitting diode. The driving module includes a first switch circuit, a second switch circuit, and a driver transistor. The first switch circuit selectively writes a gray scale voltage in a first capacitor. The second switch circuit selectively writes an offset voltage in a second capacitor. The driver transistor is coupled to the light emitting diode, the first capacitor, and the second capacitor. The driver transistor adjusts a driving current being outputted to the light emitting diode according to the gray scale voltage and the offset voltage. The gray scale voltage adjusts the voltage difference between the gate and the source of the driver transistor, while the offset voltage adjusts a threshold voltage of the driver transistor.
