Abstract
The liquid-crystal display control apparatus provided by the present invention comprises a display RAM unit for storing character codes, character-generator RAM and ROM units and for storing character font patterns and a segment RAM unit for storing picture patterns such as marks and icons. When displaying a character, the following display control is carried out. First of all, a character code is read out from the display RAM unit at a display address generated by a display-address counter . The character code is then used in conjunction with a raster address output by a line-address counter for reading out a character font pattern from the character-generator RAM unit or the character-generator ROM unit . When displaying a picture pattern such as a mark or an icon, on the other hand, the following display control is carried out. Display control information is read out from the segment RAM unit at an address generated by the display-address counter . Dot-matrix characters and picture patterns such as marks and icons are displayed on the same screen on a time-division basis.
