Abstract: A method of compensating an image to be display on a display panel is disclosed. In one aspect, the method includes receiving a first input image and adjusting a contrast sensitivity of the first input image. The method also includes calculating a first derivative of luminance of a pixel included in the adjusted image, calculating a second derivative of the luminance of the pixel, and accumulating the first and second derivatives. The method further includes determining a burn-in causing boundary based at least in part on the accumulated first and second derivatives, receiving a second input image, and comparing the burn-in causing boundary to a boundary of the second input image to determine whether to apply burn-in compensation. The method finally includes compensating a portion of the second input image corresponding to the burn-in causing boundary based at least in part on an unsharpening filter.
