Abstract

PURPOSE:To enable the easy production of the display device of a large screen at a low cost by adjacently disposing many sets of one set of neon tubes on one plane and controlling the brightness of the neon tubes. CONSTITUTION:The neon tubes 1R, 1G, 1B are bent to a U shape and both ends thereof are fixed to plugs 2. The neon tubes 1R which emit red light, the neon tubes 1G which emit green light and the neon tubes 1B which emit blue light are respectively produced as the neon tubes and are mounted to a power feed board 7. This power feed board 7 is partitioned to plural block chambers 5 by partition plates 3, 4,... having the front surfaces intersecting orthogonally with each other. The plugs 2 of the neon tubes 1R, 1G, 1B are freely attachably and cletachably inserted into sockets 6 provided in the respective block chambers 5. The power source voltages applied via the sockets 6 to the neon tubes 1R, 1G, 1B are controlled to control the brightness of the respective neon tubes, by which the color tones optically synthesized for each of the respective block chambers 5 are changed. Characters, graphics, etc., are thus displayed in full colors.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large-screen electronic display device for displaying characters and the like in a large size with a large number of neon tubes.

[0002]

2. Description of the Related Art Liquid crystal, electroluminescence, plasma displays and the like have been conventionally known as electronic character display devices. On the other hand, as is well known, a neon tube is a long and narrow glass tube in which neon gas and a circular electrode are enclosed, and has been used as a neon sign for a long time in signboards and advertising lights by bending it into various shapes.

[0003]

By the way, if the above-mentioned conventional display device is made very large so that it can be viewed from a long distance for the purpose of enhancing the advertising effect, the manufacturing cost becomes extremely high, and There were technically unresolved points and it was difficult to realize.

[0004]

Therefore, the present invention is intended to provide a large-screen electronic display device at a low cost by using a neon tube which has been widely used as a neon sign. The present invention relates to U
At least two neon tubes that are bent in a letter shape and have different emission colors are juxtaposed with their bent portions facing forward, and a large number of adjacent neon tubes are arranged adjacent to each other on one plane. However, the brightness of each neon tube is controlled.

[0005]

By arranging the bent portions of the U-shaped neon tubes side by side so as to face forward, the neon tubes can be used as a lighting source with high optical density, and clear display and low cost can be provided. Become.

[0006]

An embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the neon tube used here is bent in a U shape, and both ends thereof are fixed to the plug 2. In this neon tube, a neon tube 1R that emits red light, a neon tube 1G that emits green light, and a neon tube 1B that emits blue light are manufactured. Each of the neon tubes has a power supply board 7 shown in FIG.
Be attached to.

The power supply board 7 is a partition plate 3 whose front faces are orthogonal to each other.
Sockets 6 and 6 partitioned by a plurality of compartments 5 and 5 by 3 ...
The plugs 2 of the neon tube 1R, the neon tube 1G, and the neon tube 1B can be removably inserted into.

Then, the power supply voltage applied to the neon tube 1R, the neon tube 1G, and the neon tube 1B through the sockets 6, 6 ... Is controlled by a control device (not shown), and the brightness of each neon tube is controlled. The color tone that is optically combined can be changed for each of the compartments 5, 5, ... By controlling the, and characters, figures, etc. can be drawn in full color on this display device.

It should be noted that full color display is possible by adopting one set of neon tubes that emit red, green, and blue ternary colors, respectively. However, in the present invention, such a combination of colors is not always necessary. However, the color can be changed by controlling the brightness of both neon tubes by forming a set of at least two neon tubes having different emission colors, and a sufficient function as a display can be exhibited.

[0010]

As described above, according to the present invention, a neon tube bent in a U shape is used as a pixel, and the brightness can be controlled to display with a change in color. There is a beneficial effect that the device can be easily manufactured at low cost.
