ABSTRACT:
A display controller includes a blanking adjustment signal generation section which generates first and second horizontal blanking adjustment signals for respectively setting first and second horizontal blanking periods; first and second horizontal blanking period setting registers in which periods until the first and second horizontal blanking adjustment signals change are respectively set; and a grayscale clock signal generation section which generates first and second grayscale clock signals, which have first to N-th grayscale pulses within predetermined periods specified by the first and second horizontal blanking adjustment signals, respectively. The first horizontal blanking adjustment signal and the first grayscale clock signal are output to the first data driver, and the second horizontal blanking adjustment signal and the second grayscale clock signal are output to the second data driver.
