摘要：: An image displayer having a function of automatically eliminating an afterimage, comprises a signal processing unit for processing signals inputted from an external device and outputting video signals and audio signals to a display and a speaker, respectively, 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, and a control unit for controlling the signal processing unit to display an afterimage-eliminating picture on the display when a signal corresponding to the non-presence of the user within the predetermined range is outputted from the detecting sensor, thereby eliminating the afterimage caused due to the still picture. Accordingly, the afterimage eliminating function is automatically performed without manipulation input of the user.
