Classification: CPC G | IPC G

Claim 14:
15. A method of driving a display panel, the method comprising:
determining a level of a gate power voltage based on a compensation duty ratio corresponding to a ratio between a display duration of a normal image and a display duration of a compensation image of a first image frame;
generating a gate signal based on the gate power voltage;
outputting the gate signal to a gate line; and
outputting a data voltage to a data line based on input image data,
wherein a level of at least one of a high voltage or a low voltage of the gate signal is adjusted based on the level of the gate power voltage to compensate for a change in a charge rate of the data voltage to a pixel,
wherein a driving controller is configured to control the outputting of the gate signal to the gate line and the outputting of the data voltage to the data line, and
wherein the driving controller comprises:
a compensation image insertion enable determiner configured to enable and disable a compensation image insertion; and
a compensation duty ratio determiner configured to determine the compensation duty ratio, and output the compensation duty ratio to a power voltage generator to determine the level of the gate power voltage, when the compensation image insertion is enabled.
