ABSTRACT:
A display system comprises a first image memory storing first image data, a second image memory storing second image data operable independently from the first image memory, a display selection and combination circuit, and two display units. The display selection and combination circuit connected to the first and second image memories is formed such that each of the display units displays a combination of data from the image memories according to a display request. Normally, the display units are cathode ray tubes or liquid crystal displays. Usually, one of the first and second image memories stores character information, such as letters and numerals, and the other stores graphic information, such as figures and curves.
