ABSTRACT:
A display control apparatus comprises a control signal generator for generating various control signals including pixel video data and a display clock signal synchronous to the pixel video data, a flat-panel controller for driving a flat-panel display according to the control signals, a color palette RAM for color-converting the pixel video data supplied from the control signal generator into a digital RGB signal, and a video DAC for converting the digital RGB signal supplied from the color palette RAM into an analog RGB signal in response to the display clock signal supplied from the control signal generator to drive an analog color CRT display. Particularly, the control signal generator includes a power-down controller for supplying a power-down signal to the video DAC in response to data indicating a use of the flat-panel display, and performing a control of the display clock signal to complete a sequence of the digital-to-analog conversion which has been started at the time of supplying the power-down signal.
