Problems solved by technology

Also, in the case of LCD, after the continuously displayed still image is replaced by a new image, the LCD cannot respond quickly to the change of the video signal, so that afterimages remain due to the still image
Such afterimages degrade image quality, leading to consumer complaints and other problems

Abstract

A display apparatus having a display panel displaying an image thereon, including a GUI generator providing a graphic user interface to set an afterimage elimination area, in which an afterimage is to be eliminated, on the display panel; a user input unit allowing a user to set the afterimage elimination area through the graphic user interface; and a controller controlling the GUI generator to display an afterimage elimination image in the afterimage elimination area set by operating the user input unit on the display panel. With this configuration, the general inventive concept provides a display apparatus and a method of eliminating an afterimage, in which an afterimage elimination can be applied to only a specific area of the display panel.

Description

technical field [0001] The general concept of the present invention relates to a display device and method for removing afterimages, and more particularly, to a display device and method for removing afterimages in which afterimage removal is applied only to a specific area of ​​a display panel. Background technique [0002] Cathode ray tubes (CRTs) are commonly used in display devices, but CRTs are relatively heavy and bulky, and relatively power hungry. Therefore, recently, flat panel displays (FPDs) are widely used for display devices. Such an FPD uses a liquid crystal display (LCD) panel, a plasma display panel (PDP), or the like. [0003] PDPs and LCDs are widely used in computer monitors, televisions (TVs), and the like. In the case of a computer monitor, an image may be displayed for a long time, that is, a static image is often displayed for a long time. Also, in the case of TV, it is common to display a static image such as a color bar image for a long time. [...
