Abstract

A display system includes a signal source to provide a video signal and location information on a partial area of a display picture which is selected in order to control an image display state, a signal processor to process the input video signal to be converted to a predetermined display resolution from an intermediate resolution based on an output resolution of the video signal input from the signal source, and a control unit which corrects location information from the signal source in correspondence to the intermediate resolution and provides the corrected location information to the signal processor.

Description

[0001] This application claims priority based on Korean Patent Application No. 2005-0113153 filed with the Korean Patent Office on November 24, 2005 under U.S.C. §119(a), the entire contents of which are incorporated herein by reference. technical field [0002] The present general inventive concept relates to a display device, a display system, and a control method thereof, and in particular, to a display device, a display system, and a control method thereof that establish an arbitrary area on which an image is displayed.
