Abstract
A horizontal position adjusting circuit for a raster includes a reference voltage outputting unit for outputting a reference voltage to enable a raster to be centered on a fluorescent screen; a reference voltage adjusting unit for varying an output voltage of the reference voltage outputting unit in accordance with an operating mode for displaying an image signal; and a deflection voltage outputting unit for generating a deflection voltage in accordance with the output signal of the reference voltage outputting unit, and for applying it to a horizontal deflection coil. In accordance with the present invention, the position of the raster formed on the fluorescent screen of the cathode-ray tube is automatically adjusted according to the operating mode so that positioning of the image screen on the fluorescent screen is simply adjusted to be at the center of the fluorescent screen, resulting in improved reliability of the display device.
