Abstract

An image display device capable of preventing screen burning or residual image phenomena is provided. The image display device includes a display which displays an image according to preset pixel output characteristics; a motion detection unit which detects motion of the displayed image; and an output controller which adjusts the pixel output characteristics of pixels corresponding to a still image if at least one portion of the image is determined to be a still image, based on the detection result of the motion detection unit. Therefore, screen burning or residual image phenomena can be effectively reduced.

Description

technical field [0001] Apparatuses and methods according to the present invention relate to displaying images, and more particularly, to displaying images in which image motion is detected and pixel output characteristics are adjusted in accordance with said detection so that display burning or Afterimage phenomenon. Background technique [0002] Recently, various display devices have been developed and widely distributed as a substitute for cathode ray tube (CRT) display devices as a result of the development of digital technology. A newly developed display device has relatively light weight and is easy to install, and has a larger screen size and lighter thickness than the CRT display device. Specifically, displays using liquid crystal displays (LCDs) or plasma display panels (PDPs) are currently being focused. [0003] However, if a still image is displayed on such a display for more than a predetermined period of time, pixels at a portion where the still image is displ...
