Video signal processing circuit and display apparatus comprising the same

A video signal processing circuit processing an input video signal and outputting the video signal to the display panel comprising:

• a processor which procesess the input video signal;
• a picture quality improving part which improves picture quality of the processed video signal;
• and
• a switch which switches output of the video signal processed through the processor to one of the picture quality improving part and the display panel.

A video signal processing circuit comprising:

• a decoder;
• a de-interlacer;
• a scaler;
• an image-enhancer;
• a display;
• a first switch which switches output of a video signal output from the decoder to one of the scaler and the de-interlacer;
• and
• a second switch which switches output of the video signal output from the scaler to one of the image-enhancer and a display.

A method for avoiding delays associated with processing a video signal for a display, the method comprising:

• receiving an input video signal by a processor;
• inputting, by a user, a mode for processing the input video signal;
• processing the received video signal according to the mode,
• wherein the mode comprises a general processing mode in which quality of the input video signal is enhanced and a bypass mode in which improving the quality of the received video signal is omitted.
