  • Publication number: 20200279529
    Abstract: A method for driving a display device includes stopping a display operation of a display based on a presence or absence of a signal indicating an off operation of a main power switch of the display. The method further includes applying a recovery voltage across a gate and source of a driving transistor in the display based on a threshold voltage shift of the driving transistor. The threshold voltage shift is determined during a stopped state of the display operation of the display. The stopped state of the display operation of the display occurs prior to starting the display operation of the display.
