Abstract
An image sticking prevention circuit for a display. The image sticking prevention circuit comprises a diode, a first capacitor, a transistor, and a second capacitor. The first terminal of the diode is coupled to a first voltage terminal of a voltage converter. The first capacitor has a first terminal coupled to the second terminal of the diode and a second terminal coupled to a first fixed potential. The transistor has a first terminal coupled to the first terminal of the first capacitor, a second terminal coupled to the first terminal of the diode and the first voltage terminal of the voltage converter, and a third terminal coupled to a second voltage terminal of the voltage converter and a gate driver circuit. The second capacitor has a first terminal coupled to the third terminal of the transistor and a second terminal coupled to a second fixed potential.
