Title:
DISPLAY CONTROLLER
Document Type and Number:
Japanese Patent JPH04369688
Kind Code:
A
Abstract:
PURPOSE: To obtain a display oscillation signal of frequency corresponding to plural horizontal synchronizing signals.
CONSTITUTION: The display controller is provided with a prescaler 5 which divides the frequency of the display oscillation signal from a display oscillation circuit 4 and a phase comparing circuit 6 which compares the phase of the frequency-divided display oscillation signal with the phases of the horizontal synchronizing signals to obtain the display oscillation signal for the horizontal synchronizing signals by the one display oscillation circuit 4 without placing any load on a CPU 2.
