ABSTRACT:
The invention provides display controllers, display units and electronic apparatuses using the same, which can achieve transfer rates that can accommodate increases in the amount of display data that may result from increases in the screen size of liquid crystal panels in the future with low power consumption. The display unit includes a liquid crystal panel (display section), a display data RAM that stores display data for at least one frame, an X driver IC (display controller) that display-drives the liquid crystal panel at a given frame cycle, and a Y driver IC that scan-drives the liquid crystal panel. Display data is supplied from the MPU to the X driver IC through a differential IF. The MPU supplies display data at a high-speed transfer rate with the differential IF, using a dummy blanking period, and stops the operation of the differential IF until the next display data transfer timing.
