Inventor： Shinji Takasugi ,  Hae Yoon Kang ,  Mi Hee Uhm

IPC: G09G5/18 ,  G09G3/32

CPC classification number: G09G5/18 ,  G09G3/3233 ,  G09G2300/0452 ,  G09G2300/0842 ,  G09G2320/0295 ,  G09G2320/043 ,  G09G2340/0457

Abstract: The present application relates to a display apparatus having a panel including sub-pixels, data lines, and horizontal lines; a sensing circuit to collect sensing data by sensing for external compensation in the horizontal lines; a calculator to determine a characteristic change of each of the sub-pixels using the sensing data to calculate an external compensation value; a data aligner to receive input image data, and when the input image data corresponds to a horizontal line where the sensing is performed, to convert the input image data into compensation image data based on a compensation value; and a data driver to output a compensation data voltage corresponding to the compensation image data to a data line corresponding to the sensed horizontal line before and after the sensing is performed, and output a sensing data voltage to the data line while the sensing is performed.
