Abstract
A display controller for a display may include a frame rate circuit to change a frame rate of the display from a first frame rate to a second frame rate, and a reference voltage circuit to adjust a reference voltage of the display from a first reference voltage corresponding to the first frame rate to a second reference voltage corresponding to the second frame rate. The display may be a thin film transistor liquid crystal display. The reference voltage may correspond to a common voltage (Vcom) for the display.
