Display apparatus and control method of the same

A display apparatus comprising:

• a display panel which has a plurality of pixels;
• a panel driver which applies a gray scale value corresponding to an image signal to corresponding pixels;
• a highlight detector which detects high gray level pixels having gray scale values greater than a predetermined high gray scale value, and a highlight zone comprising the detected high gray level pixels, wherein a gray scale value difference between boundary pixels of the highlight zone and adjacent pixels is greater than a predetermined reference difference;
• and
• a controller which controls the panel driver to apply a gray scale value greater than a gray scale value of the high gray level pixels to a surrounding zone adjacent the highlight zone.
