撮像機能一体型表示装置
Document Type and Number:
Japanese Patent JP4759511
Kind Code:
B2
Abstract:
An image display device according to the present invention is disclosed wherein a display function is added to an area sensor in which an optical sensor (constituted by a thin film light sensing diode) and a TFT are disposed in two dimensions on a transparent substrate to form a read function. Pixels each having a read function are each provided with a light transmitting area, and the thin film light sensing diodes and the TFTs are each formed using a substantially transparent material, so that the device itself is transparent. Therefore, a user can directly see the contents of a printed matter while the area sensor is placed on the printed matter. Further, an image can be read by, for example, designating the image required for the user from above the device. Consequently, it is possible to decrease the power consumption of the device.
