Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an information display device for displaying information on a reflective or transmissive screen, and particularly to information display devices for displaying information on information processing devices such as microcomputers, etc. It is most suitable for use in display devices.

Background technology and its problems Information processing devices such as microcomputers usually have OR,
A T-display is connected, and data and images are displayed. However, such an OR,T device has a limited display area, and can only be viewed by the person operating the information processing device or those around the person.

OBJECTS OF THE INVENTION In view of the above-mentioned problem K, it is an object of the present invention to provide an information display device intended for tens to hundreds of people.

Summary of the Invention The information display device according to the present invention has a liquid crystal layer interposed between transparent electrodes disposed on each of the front side and the back side transparent plates, for example, in an X-Y matrix shape, and displays light according to information to be displayed. A display body capable of forming a transmissive portion and a non-transmissive portion of the display body, and an optical device for enlarging the preliminarily passed through the display body and projecting the image onto a reflective or transmissive screen.

With such a configuration, it is possible to obtain a display device that targets a large number of people.

Examples of the invention The present invention will be described below with reference to Examples.

FIG. 1 is a block diagram schematically showing an information display device according to the present invention. In FIG. 1, light from a light source (1) is converted into parallel light I!jVc through a condenser lens (21t-) and is irradiated onto a translucent display (3).This display (3)
is a light-transmissive display using a liquid crystal display, and is used as a film for a normal slide glodictor. The display body (3) is driven by the output button of the microcomputer (6), and required numerical or character data, images, etc. are displayed as transparent or opaque parts. Such data and images are formed by arithmetic processing by a microcomputer (6) of all input data from a key human power device (power and disk drive device (8)) connected to the microcomputer (63K).

The light that has passed through the transparent part of the display (3) is passed through the magnification lens (4).
)<Therefore, it is enlarged and projected onto the screen (5).

As a result, the output data and output image of the microcomputer (6) are displayed on the screen (51K grayscale image).
Information can be transmitted to dozens to hundreds of people. Note that the screen (5) may be a reflective screen or a transmissive screen.

Is Fig. 2 the structure of the display body (3) in Fig. 1? FIG. The display body (3) has a liquid crystal layer (9) enclosed or inserted between two transparent plates (QO) 10 such as glass plates. Side I of the liquid crystal layer (9) of each transparent plate Ql (11)
A plurality of transparent electrodes Q2 (13) formed of CId, 8nOz, etc. are arranged in the vertical and horizontal directions. Then, a voltage of K is applied to the liquid crystal layer (9) through these transparent electrodes α7J (131c). Dot matrix display is performed by creating optical anisotropy in the display material at positions corresponding to the lattice points of each electrode.In addition to dot matrix display, segment display and sound can be used as display formats. Further, it is also possible to display the shape of the electrode αB (13) in a graphical manner.Also, the display body (3) can be displayed in t-color, and the screen (5) can also be displayed in color.

Although the present invention has been described above based on the embodiments, various modifications can be made in accordance with the technical idea of the present invention.

For example, the information displayed by the display (3) is not limited to the output of the microcomputer (6), and may be information transmitted via wire or wireless. Further, as the screen (5), it is also possible to use it, for example, as a TV size transmission screen or as a substitute for an ORT screen.

Effects of the Invention As described above, the present invention uses a light-transmissive liquid crystal display to enlarge and display the displayed information on the screen, so it can provide information to a large number of people with a very simple configuration. A display device 11t can be obtained.
