DISPLAY APPARATUS AND METHOD OF DRIVING THE SAME

摘要

A display apparatus includes a display panel displaying a normal image in a normal mode and displays a static image in a PSR (Panel Self Refresh) mode, a memory storing refresh image data corresponding to the static image, a comparator comparing image data of an N-th frame received from a graphics processor and refresh image data readout from the memory, a compensator generating a compensation value based on a comparison result and adding the compensation value to the refresh image data, and a data driver generating a data voltage using the refresh image data compensated by the comparator and outputting the data voltage to the display panel.

1. A display apparatus comprising:
a display panel configured to display a normal image in a normal mode and display a static image in a PSR (Panel Self Refresh) mode; a memory configured to store refresh image data corresponding to the static image; a comparator configured to compare image data of an N-th frame received from a graphics processor and refresh image data readout from the memory; a compensator configured to generate a compensation value based on a comparison result and adding the compensation value to the refresh image data; and a data driver configured to generate a data voltage using refresh image data compensated by the compensator and outputting the data voltage to the display panel, wherein the N-th frame is a selected frame corresponding to the static image in the PSR mode.
