Abstract

Apparatus and method for controlling a screen of an image display device on which an image signal transmitted from a PC can be displayed are provided. In the above apparatus and method, a TV mode and a PC mode are discerned by a selection of a user. In the case of a fast moving picture like in a TV, a fast display frame rate is set, and in the case of many slow moving pictures or still images, a normal display frame rate is set. In the PC mode having a fast moving picture, a motion degree is sensed such that the fast display frame rate is set, thereby preventing an increase in power consumption in advance. Also, a display frame rate most suitable to a display module can be set to thereby improve a life time problem of the display module, so that a user can view a natural screen without an afterimage phenomenon to enhance a user satisfaction.

Description

Technical field [0001] The present invention relates to an image display device, and more specifically, to an apparatus and method for controlling a screen of an image display device that can display an image signal sent from a personal computer (PC), wherein the TV mode and the PC mode are distinguished from each other On, the display frame rate can be adjusted automatically. Background technique [0002] Recently, due to the development of technology for processing external image signals, it is possible to use a TV as a monitor of a PC by setting the external input mode of the TV to the PC input mode, and connecting the image signal output line of the PC to the TV PC input terminal among input terminals. That is, it is possible to display the PC operation screen on the TV. At this time, as the PC operation screen displayed on the TV, there is a window screen. Among these operation screens, the window operation screen has a vertical frequency of 60 Hz. Summary of the inventi...
