  • Display device
    Patent number: 11244631
    Abstract: A display device includes a display panel including data lines, gate lines which cross the data lines, and pixels; a gamma voltage generator configured to generate first to nth gamma voltages, n being an integer; and a data driver configured to generate data voltages by selecting the gamma voltages according to input image data, and to supply the data voltages to the data lines, wherein the gamma voltage generator comprises a first voltage dividing unit configured to divide a reference voltage; a first voltage dividing circuit configured to generate the first gamma voltage by selecting voltages output from the first voltage dividing unit according to a highest gamma register value; and a second voltage dividing circuit configured to generate the second to nth gamma voltages using the reference voltage.
