ABSTRACT:
There is provided an image input device-integrated type display device concurrently having an image display function, a document image input function, and a pen input function. A common electrode of the image input device-integrated type display unit is formed on a glass plate. A segment electrode is formed on a micro lens of a glass plate. An island electrode located at each pixel is connected to the segment electrode via a photoconductor. Liquid crystals are interposed between the common electrode and the island electrode. In an image input mode, light reflected on a document is applied to the photoconductor to control a voltage applied to the liquid crystals. In a pen input mode, light from an input pen is applied to the photoconductor to control a voltage applied to the liquid crystals. In an image display mode, a voltage applied to the liquid crystals is controlled according to image data of each pixel. Thus brightness data of the document, position data of the input pen, and image data corresponding to a display signal are written into the image input device-integrated type display unit.
