Abstract: An image processing method is applied to an image display device, the image display device includes a lens having distortion coefficients and a display screen. The image processing method includes: dividing a display region of the display screen into image regions according to the distortion coefficients of the lens, an outer boundary line of each image region enclosing a polygon, a geometric center of the polygon enclosed by the outer boundary line of the image region coinciding with a geometric center of the lens, and distortion coefficients of positions of the lens on which vertexes of the polygon enclosed by the outer boundary line of the image region are mapped being the same; and performing anti-distortion processing on coordinates of vertexes of the image region according to a distortion coefficient corresponding to the vertexes of the image region to obtain texture coordinates of the vertexes of the image region.

Abstract: 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.
