<p>PURPOSE:To obtain the input / output integrating display device with the sense of 'paper and pencil' by forming the device by bonding plural block plates by a transparent adhesive agent. CONSTITUTION:For a parallax correction plate 3, optical fibers are bundled and adhered, small block pieces are prepared by slicing them in a direction rectangular to a lengthwise direction, and these small block pieces are bonded only for the area of a plane display. In this case, when a handwritten stroke is inputted to a sensor plate 2 of a coordinate input device, the image of a plane display 4 is radiated with a back light 5, and formed on the front face of the parallax correction plate 3 or on the back of an image formation sheet. Then, the image is projected on the transparent sensor plate 2 of the coordinate input device so as to observe the inputted handwritten stroke 6. Thus, the low- priced and easily workable parallax correction plate can be obtained.</p> |
