DISPLAY DEVICE AND METHOD FOR CONTROLLING DISPLAY DEVICE

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. 根据本公开内容的实施方式，一种用于控制显示装置的方法包括：在垂直同步信号的每个帧输入周期输入帧数据；在垂直同步信号的每个空白周期，基于帧数据以预定的累积单位累积一些像素的应力数据；基于所有像素的应力数据的累积完成时累积的输入时间，计算用于校正累积的应力数据的校正增益值；基于校正增益值来校正累积的应力数据；和存储校正过的累积的应力数据。
