Classification: CPC G | IPC G

Claim 0:
1. A display apparatus comprising:
a display panel comprising:
a gate line;
a data line; and
a pixel electrically connected to the gate line and the data line, and

configured to display a normal image and a compensation image in a first image frame;
a gate driver configured to output a gate signal to the gate line;
a data driver configured to output a data voltage to the data line; and
a power voltage generator configured to vary a level of a gate power voltage based on a compensation duty ratio corresponding to a ratio between a display duration of the normal image and a display duration of the compensation image of the first image frame,
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 the pixel,
wherein the display apparatus further comprises a driving controller configured to control an operation of the gate driver and an operation of the data driver, 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 the power voltage generator, when the compensation image insertion is enabled.
