    摘要: An image distortion correction circuit performs a distortion correction process on an image signal on the basis of distortion correction data to generate a distortion-corrected image signal. The distortion correction data is for correcting coordinate positions of display data fragments corresponding to respective N coordinate positions in the display image to first to N-th distortion correction coordinate positions. The image distortion correction circuit determines a distortion correction coordinate position where abnormality occurs as an abnormal coordinate position among the first to N-th distortion correction coordinate positions on the basis of respective intervals between the adjacent first to N-th distortion correction coordinate positions indicated by the distortion correction data. The image distortion correction circuit corrects a part corresponding to the abnormal coordinate position in the distortion correction data on the basis of at least the two distortion correction coordinate positions excluding the abnormal coordinate position among the first to N-th distortion correction coordinate positions.

    摘要: A display device has: a display panel; a source driver group including 2j source drivers that are arranged in the lengthwise direction of gate lines; and a display controller that is connected to the 2j source drivers via j data supply lines provided in common between adjacent pairs of source drivers. The display controller outputs j pixel data piece groups, into which m/2 pixel data pieces were divided, to the data supply lines. The (2k)th source driver receives m/(4j) pixel data pieces via a data supply line, and receives three pixel data pieces from the (2k+1)th source driver. The (2k)th source driver generates m/(2j) of gradation voltage signals on the basis of the pixel data pieces.
