Abstract
According to an embodiment of the present disclosure, a method for controlling a display device includes inputting frame data for each frame input period of a vertical synchronization signal, accumulating stress data for some pixels in predetermined accumulation units based on the frame data for each blank period of the vertical synchronization signal, accumulating an input time of the frame data, calculating a correction gain value for correcting the accumulated stress data based on the input time accumulated when the accumulation of the stress data is completed for all pixels, correcting the accumulated stress data based on the correction gain value, and storing the corrected accumulated stress data.

A method for controlling a display device, comprising:
- inputting frame data for each frame input period of a vertical synchronization signal;
- accumulating stress data for some pixels of the display device in predetermined accumulation units based on the frame data for each blank period of the vertical synchronization signal;
- accumulating an input time of the frame data;
- calculating a correction gain value for correcting the accumulated stress data based on the input time accumulated when the accumulation of the stress data for all pixels is completed;
- correcting the accumulated stress data based on the correction gain value;
- and
- storing the corrected accumulated stress data.
A display device, comprising:
- a display panel having thereon a plurality of pixels;
- a data driver configured to drive a data line of the display panel;
- a gate driver configured to drive a gate line of the display panel;
- and
- a timing controller configured to control driving of each of the data driver and the gate driver,
- wherein the timing controller is configured to receive a vertical synchronization signal including at least one frame input period and at least one blank period,
- wherein the timing controller is configured to be inputted with frame data for each frame input period of the vertical synchronization signal, accumulate stress data for some pixels among the plurality of pixels in predetermined accumulation units based on the frame data for each blank period of the vertical synchronization signal, accumulate an input time of the frame data, and calculate a correction gain value for correcting the accumulated stress data based on the input time accumulated when the accumulation of the stress data is completed for all pixels.
