Classification: CPC G | IPC G

Claim 11:
12. A display device, comprising:
a display panel including a first pixel electrically coupled to a first gate line and a data line and a second pixel electrically coupled to a second gate line and the data line;
a gate driver configured to provide a gate signal to the first and second gate lines; and
a data driver configured to provide a data signal to the data line,
a timing controller configured to generate frame data based on input image data provided from an external device and to generate attenuated data by downscaling grayscale values included in the frame data,
wherein a frame image is displayed during each of a first frame period and a second frame period, and each of the first and second frame periods includes a first sub-frame period and a second sub-frame period, and
wherein the gate driver is configured to:
provide the gate signal to each of the first gate line and the second gate line during the first sub-frame period in each of the first and second frame periods, and alternately provide the gate signal to the first gate line and the second gate line during the second sub-frame periods of the first and second frame periods,

wherein the data driver is configured to provide a first data signal to the data line during each first sub-frame period, and to provide a second data signal to the data line during each second sub-frame period,
wherein the second data signal is different from the first data signal and varies dependent on the first data signal,
wherein the data driver is configured to generate the first data signal based on the frame data and to generate the second data signal based on the attenuated data, and
wherein the timing controller is configured to calculate a second grayscale value included in the attenuated data by multiplying a scaling factor by a first grayscale value included in the frame data.
