Display apparatus and method of driving display panel using the same

A method of driving a display panel, the method comprising:

• inserting a compensation image to first image data including a normal image to generate second image data;
• determining a compensation counting value corresponding to the compensation image;
• shifting an output time of a gate signal;
• outputting the gate signal having a shifted output time to the display panel;
• generating a data voltage based on the second image data;
• and
• outputting the data voltage to the display panel,
• wherein a gate shift value of a gate signal applied to a gate line for applying the compensation image is the same as a gate shift value of a gate line disposed immediately before the gate line for applying the compensation image, and
• wherein the gate shift value is a difference in time between a gate signal applied to pixels connected to one gate line and data voltages applied to the pixels connected to the one gate line.

A display apparatus comprising:

• a display panel;
• a driving controller inserting a compensation image to first image data including a normal image to generate second image data;
• a gate driver shifting an output time of a gate signal and outputting the gate signal having a shifted output time to the display panel;
• and
• a data driver generating a data voltage based on the second image data and outputting the data voltage to the display panel,
• wherein, when an L-th compensation image is inserted between an M-th normal image and an M+1-th normal image, a second interval between an M-th gate pulse corresponding to the M-th normal image and an M+1-th gate pulse corresponding to the M+1-th normal image is greater than a first interval between an M−1-th gate pulse corresponding to an M−1-th normal image and the M-th gate pulse corresponding to the M-th normal image, where M is a positive integer equal to or greater than two and L is a positive integer,
• wherein, when a number of the compensation images inserted between the M-th normal image and the M+1-th normal image is N, the second interval is N+1 times the first interval, where N is a positive integer equal to or greater than 1, and
• wherein the driving controller determines a compensation counting value corresponding to the compensation image.
