Abstract
A display device includes a display screen, and horizontal and vertical display signals. The horizontal and vertical display signals are to render an image on the display screen. A first and second accelerometers are directly coupled to the display screen. First and second compensation circuits convert acceleration in horizontal and vertical directions respectively to x- and y-compensation signals. First and second adders combine the x- and y-compensation signals with the horizontal and vertical display signals to dynamically adjust a location of the image on the display screen while the display device is subject to movement.
