Abstract
A display system and a method of eliminating a residual image on a display causes an on screen display (OSD) block to be moved to different locations on the display to eliminate the residual image. In a method embodying the invention, a mixed video image that includes a video image from a video source and at least one OSD block is generated. Thereafter, the mixed video image is displayed on a display screen to thereby eliminate a residual image on the display screen and the at least one OSD block is scanned to different positions on an active image portion of the display screen. In a progressive scanning mode, the OSD block is progressively scanned across the active image portion. On the other hand, in a random scanning mode the at least one OSD block is randomly moved to different locations on the active image portion of the display screen for a predetermined period of time.
