摘要： A display device, a method for driving the same, and a display system are provided. In the display device, a drive circuit can first drive the display panel to display a target image containing a number of colors less than a number threshold in response to detecting that a host computer stops delivering image data (i.e., the screen is turned off), and then drive the display panel to enter a standby state. In this way, the display panel can be made to stably transition to the standby state upon screen-off of the host computer, thereby solving the problems of stalled display or abnormal display caused by the display panel being unable to enter the standby state reliably.
