Patent ID: 7586546

Claim:
A display apparatus having a display, the display apparatus comprising: a video signal processor comprising: a processor which processes an input video signal, and a picture quality improving part which improves picture quality of the processed video signal, wherein the video signal processor processes the video signal through a path comprising a signal processing path to selectively bypass the picture quality improving part; a selection input part which receives a user input regarding a selection of a bypass mode corresponding to the signal processing path; a switch which switches the video signal output from the processor to be output to at least one of the picture quality improving part and the display; and a controller which controls the video signal processor to output the video signal processed through the processor to the display, after bypassing the picture quality improving part if the user selects the bypass mode through the selection input part, wherein the picture ciuality improving part comprises a plurality of picture quality improving integrated circuits (ICs), and the controller controls the video signal processor to bypass at least one of the plurality of picture quality improving ICs if the user selects the bypass mode through the selection input part.
