摘要： A display device is disclosed. In one embodiment, the display device includes a first conversion unit receiving gray data and outputting a gray data value of a second gamma curve, which has a luminance equal to a luminance of the gray data on a first gamma curve. The device may also include a memory storing a look-up table (LUT) which includes first and second data groups and compensated gray data for the second gamma curve. The device may further include a reference unit generating the compensated gray data based on the two converted gray data. Coordinates formed of i) each value in the first data group and ii) each value in the second data group may correspond to any one of the compensated gray data.

摘要： A display device includes a display panel having first and second display areas. A data driver provides data and bias voltages to data lines. A timing controller controls the data driver and a scan driver based on at least two operation modes. The first mode drives the first and second display areas at a normal frequency, and the second mode drives the first display area at a first frequency substantially equal to or lower than the normal frequency and the second display area at a second frequency lower than the first frequency. The second mode includes an active frame to write a reference voltage to display a black image in the second display area, and blank frames to maintain the reference voltage and apply the bias voltage to the pixels in the second display area. The data driver varies the bias voltage in the blank frames.
