Description

[Detailed Description of the Invention] This invention relates to a display method for displaying moving images of character patterns for advertising as optical displays. This relates to display methods.

The following will explain the embodiments shown in the drawings.

This system is characterized in that a group of optical fibers 1 is provided with a dimmer 2 interposed in the middle of each optical fiber 1, and the group of optical fibers is used as a light transmission medium from a light source 3 to a display surface 4.

The dimmer 2 has various forms, some of which will be exemplified below.

A color filter 5 is provided between the optical fibers 1a and lb which are connected in series, as shown in FIG. 2 as a side view and as shown in FIG. 3 as a front view.
The same color filter 5 is a rotary plate connected to the motor 6, and is provided with a color changing process divided into sections in the rotational direction as shown in the front view.

As shown in FIG. 4, the second filter is provided with two filters 5.5 for changing color and shade in the same manner as described above.

Further, part 3 is to move the plunger 8 into and out of the light path by means of a magnet 7, as shown in FIG.

As shown in FIG. 6, there is also a type 4 in which the light from a light source 3 such as a lamp is passed through a liquid crystal panel 9 and then sent to an optical fiber block. 10 is endothermic glass.

The present invention is constructed as described above, and the light emitted from the light source 3 is transmitted to the display surface 4 through a group of optical fibers and displayed. Display surface 4
The luminescent pattern expressed in is formed by selecting the color and density using the dimmer 2, and the selection is made by another computer.

When carrying out the present invention, since light is transmitted by an optical fiber that allows light to be bent, the structure is easy and simple to set up even when installed in an existing building, etc., and the light emitted from a single light source 3 is simple. Because it is a spraying device, it is easy to obtain high brightness, and because it avoids the frequent use of short-lived parts such as miniature light bulbs and cathode ray tubes, it has the advantage of being highly durable and inexpensive.
