Patent ID: 7403194

Claim:
An image displayer having a function of automatically eliminating an afterimage, the image displayer comprising: a signal processing unit for processing signals and outputting video signals to a display; a detecting sensor for detecting whether there exists a user within a predetermined range from the display when a still picture corresponding to video signals of an identical pattern outputted from the signal processing unit is displayed on the display beyond a pre-set time; a control unit for controlling the signal processing unit to display an afterimage-eliminating picture on the display when a signal corresponding to a non-presence of the user is outputted from the detecting sensor, thereby eliminating the afterimage caused due to the still picture; and an On-Screen Display (OSD) processing unit outputting to the signal processing unit a pre-set OSD signal indicating that the afterimage-eliminating picture is being displayed on the display, corresponding to a signal outputted from the control unit when the afterimage-eliminating picture is displayed on the display, wherein, on receipt of a signal indicating that there exists the user within the predetermined range from the detecting sensor, the control unit controls the OSD processing unit to output the pre-set OSD signal to the signal processing unit, thereby allowing the user to select whether to perform an afterimage-eliminating function.
