Abstract
A display controller which can display a cursor on either of a CRT display or a liquid crystal type display device is described. The liquid crystal type display device is a type that has an upper and lower display blocks which are scanned substantially in parallel. This display controller allows the display position of the cursor to be designated in the same manner, independent of the type of display device used. The display controller operates in a time sharing manner, alternately on the upper and lower display blocks of the liquid crystal device. Two groups of data corresponding to these upper and lower blocks are formed and are supplied to the liquid crystal display device substantially in parallel. X and Y coordinate positions of the cursor position are also stored. The cursor pattern signal for the liquid crystal display device is also stored in a time shared manner.
