Abstract

PURPOSE:To prevent the parallax to be generated due to the protection layer such as glass or the like on the display layer such as liquid crystal panels and CRTs which makes the coordinates located further than the position pointed by pens or the like which points the coordinates and to make the visible position and the position pointed by pen or the like come closer. CONSTITUTION:Plural light guides 2 as protection layer are arranged on the surface of a light emitting body 3 twodimensionally. A light emitting part 5 makes the light emitting body 3 emit light by a cathod ray 4. The light from the part 5 advances vertically through the light guide 2 like the light 6 and does not leak out. Thus, the visible display part moves on the surface of the light guide in the display device with the light guide 2 provided on the surface as protection layer so that the surface looks like shining and changes from being reflected and transparent and the parallax between the position to be pointed and the visible display position can be eliminated.

In order to achieve the present invention, a large number of light guides are two-dimensionally arranged on the surface of the display layer in order to prevent the light emitted from the original display section from traveling in a direction other than the direction perpendicular to the display surface. Since the light emitted from the display layer is guided to a desired position by the light guide, the actual display surface can be moved to the surface of the light guide. As a result, the position where the surface of the light guide is designated as the pointing portion and the displayed position match, so that it is possible to obtain an easy-to-use display device without parallax.

For example, suppose that the light emitting portion 5 located immediately below the portion designated by the coordinate designating portion 1 of the light emitting body 3 is caused to emit light by the cathode ray 4. The light emitted from the light emitting portion 5 travels in the light guide 2 in a substantially vertical direction like the light 6, and does not leak to the other. Therefore, as the display unit, the position of the surface of the light guide 2 designated by the coordinate designating unit appears to be shining, and the position of the light emitting unit 5 does not appear to shine.
That is, no parallax is generated.

FIG. 2 shows an example in which the light guide according to the present invention is arranged on the surface of the liquid crystal, and it is assumed that the display unit 8 is in the reflective state. At this time, the light from the outside travels like light 6,
Get out of the surface again. That is, it appears that reflection occurs on the surface, and the position of the display unit 8 has moved to the surface of the coordinate designating unit. On the contrary, when the display unit 9 is in the transmissive state, the light 7 from the outside passes through the display unit 9 and the light does not return to the surface. As shown in FIGS. 1 and 2, the light guide 2 has a plate-like structure in which short optical fibers are in contact with each other. Further, the size of the surface of the light guide 2 that contacts the display unit 8 and the size of the outer surface that does not contact the display unit 8 are substantially the same.
