DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a display device provided with a distortion correction function for correcting screen distortion due to the deterioration of high voltage regulation caused by a change in horizontal frequency of a received signal. SOLUTION: A frequency discrimination device 15 discriminates the horizontal frequency of the received signal on the basis of a received horizontal/vertical synchronizing signal and a distortion correction circuit 13 controls a prepared distortion correction signal on the basis of the discriminated horizontal frequency.
