               1. A display apparatus comprising: 
            a display panel; and 
                a display panel driver which drives the display panel, 
                wherein the display panel driver determines at least one selected from a first low luminance pattern and a second low luminance pattern, wherein the first low luminance pattern includes a first low luminance area at a first end portion of the display panel in a vertical direction and a second low luminance area at a second end portion of the display panel in the vertical direction, and the second low luminance pattern includes a third low luminance area at a first end portion of the display panel in a horizontal direction and a fourth low luminance area at a second end portion of the display panel in the horizontal direction, 
                wherein when the first low luminance pattern is determined, the display panel driver determines a first compensation area including a first boundary between the first low luminance area and a first normal area and a second compensation area including a second boundary between the second low luminance area and the first normal area and operates a compensation for reducing grayscale values of the first compensation area and the second compensation area, and 
                wherein when the second low luminance pattern is determined, the display panel driver determines a third compensation area including a third boundary between the third low luminance area and a second normal area and a fourth compensation area including a fourth boundary between the fourth low luminance area and the second normal area and operates a compensation for reducing grayscale values of the third compensation area and the fourth compensation area.
