Abstract

PURPOSE: To easily couple a computer system, which generates and displays various pictures, and an overhead projector by using a liquid crystal type light- transmissive display device. CONSTITUTION: A personal computer is used as the computer system, and the personal computer displays a picture on a CRT display device 2 based on information inputted from a floppy disk device 4 or a keyboard 3. A video signal for CRT picture is branched by a picture signal branch device 7 and passes a display controller 8 to display the same picture as the CRT picture on a liquid crystal type light-transmissive display device 9. Since light transmission can be controlled in the device 9 in the unit of picture elements of three primary colors of red R, green G, and blue B, the picture on the device 9 is optically expanded and projected on a screen 6 in the same manner as a normally used color transparent sheet is put on a sheet table of an overhead projector main body 5.
