Abstract

Bit map memories, which have addresses corresponding to orderly-arranged red, green and blue dots of a color display panel, are provided corresponding to red, green and blue colors, respectively, and a color array memory is provided which has prestored data indicating the array of the colors of the dots in at least one dot area of the color display panel. Bit map data are simultaneously read out of the three bit map memories in the order of arrangement of the dots of the color display panel, and the bit map data thus read out are input into a color selector. In synchronization with this data readout color array data is read out of the color array memory. The color array data thus read out is used to control the color selector to output therefrom, as a color display control signal, the bit map data of a specified color.
