Circuit For Eliminating Shutdown Afterimages of A Display Device

摘要

The invention relates to a field of display technique. There is disclosed a circuit for eliminating shutdown afterimages of a display. By designing a circuit capable of generating voltages for tuning on TFTs in a time-division way, it is realized that when the display screen shuts down, not only the significant discontinuous differences of pictures are ensured to be not perceived by human eyes so as to eliminate the shutdown afterimages, but also such a problem can be avoided that the circuitry in the panel is burned out by the overlarge instantaneous current caused by the simultaneous turning on of all the TFTs at the moment of shutdown.
