Abstract
The present application provides a method for controlling an offset voltage in a display device, a display device and a storage medium. The method for controlling an offset voltage in a display device comprises: generating a chopper signal based on at least one of a data output control signal and a polarity inversion control signal; and, controlling, according the chopper signal, the polarity of an offset voltage of an operational amplifier in the display device, so that the offset voltage is equivalently eliminated within at least one of a design space range and a design time range. By using the control method of the present application, without using large-size transistors and providing more signals, the display effect can be ensured and the size of the chip can also be reduced.
