Abstract
The disclosure provides a light emitting diode including a light emitting diode (LED), a first transistor, a second transistor and capacitor. A cathode terminal of the LED is configured to receive a first power supply voltage. A first port of the capacitor coupled to the gate of the first transistor is configured to store a data signal in a first duration. A first port of the second transistor is configured to receive a second power supply voltage. A gate of the second transistor is configured to receive a PWM signal in a second duration. A second port of the second transistor is coupled to the second port of the first transistor. The second transistor is turned on for a conducting time in the second duration according to the PWM signal, and the first transistor provides, in the conducting time, a drive current to the LED according to the data signal.
