ABSTRACT:
Each display control block processes color pixel data stored in a refresh memory to convert the processed data into 1-bit monochromatic picture signals. At this time, the color information possessed by the respective color pixel data are converted in a form in which the color information possessed by the color pixel data may be expressed on a monochromatic display panel. The monochromatic picture signals produced by plural display control blocks are synthesized in a display synthesizing circuit and converted into one monochromatic picture signal. At this time, the display synthesizing circuit synthesizes the signals with different degrees of display preference so that the picture surface having a lower display preference is not seen on the picture surface having a higher display preference.
