Method of driving display panel including compensating for flicker and display apparatus for performing the same

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

• generating a flicker value of a segment of a plurality of segments of an input image;
• compensating the flicker value of the segment based on a segment size, the flicker value of the segment, and flicker values of neighboring segments positioned around the segment;
• determining a frame rate of the display panel based on the flicker value of the segment;
• driving the display panel in the frame rate;
• and
• determining a compensation size,
• wherein the compensation size is determined by dividing a compensation threshold by the segment size,
• wherein determining whether or not to compensate the flicker value of the segment comprises:
• determining not to compensate the flicker value of the segment when the compensation size is equal to or less than 1;
• and
• determining to compensate the flicker value of the segment when the compensation size is greater than 1.

A display apparatus comprising:

• a display panel configured to display an image;
• a low frequency driver connected to the display panel and configured to generate a flicker value of a segment of a plurality of segments of an input image, to compensate the flicker value of the segment depending on a segment size, and to determine a frame rate of the display panel based on the flicker value of the segment;
• and
• a data driver connected to the display panel and configured to output a data voltage to the display panel,
• wherein the low frequency driver is configured to determine not to compensate the flicker value of the segment when the segment size is equal to or greater than a compensation threshold;
• and
• wherein the low frequency driver is configured to determine to compensate the flicker value of the segment when the segment size is less than the compensation threshold.
