    • A display apparatus is provided to prevent flickering by generating gray scale voltages having luminance difference of 1% between the most significant gray scale and a very low gray scale of the most significant gray scale. A display apparatus includes a display panel(100), a timing controller(400), and a source driver(300). The display panel includes plural pixel units. The timing controller outputs compensation gray scale data of k or (k+1) gray scale of (a-d) bits corresponding to higher (a-d) bits of original gray scale data according to lower d-bits of original gray scale data. The source driver converts the compensation gray scale data into gray scale voltages and outputs the gray scale voltages to the pixel units. If luminance of the most significant gray scale is 100%, luminance difference between the most significant gray scale and a very low gray scale of the most significant gray scale is 1%.
