Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A display device, comprising:
a display panel including a pixel electrically coupled to a gate line and a data line;
a gate driver configured to provide a gate signal to the gate line;
a data driver configured to provide a data signal to the data line; and
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 the gate driver is configured to sequentially provide a first gate signal and a second gate signal to the gate line during a first frame period,
wherein the data driver is configured to provide a first data signal to the data line in response to the first gate signal, and to provide a second data signal to the data line in response to the second gate signal,
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.
