Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a large display panel for a display device, a monitoring device, a training simulator device, etc., and particularly relates to a fully illuminated double display panel.

Technical background In recent years, display panels and CRT displays have become increasingly crowded in terms of practical use in display devices, monitoring devices, and training simulator devices, especially compared to display panels, which have the disadvantage of not being able to keep up with the diversity of system displays. With the rapid advancement of CRTs, there is a growing argument that CRT displays alone can fulfill the role of display panels, and that there is no need for display panels.

However, CRT displays have small screens and are difficult to handle when a large number of people are using them.
There is a strong demand for a large-area display panel that has the same functions as the conventional one.

Purpose and Structure of the Invention The present invention was devised in response to the above-mentioned needs, and is capable of removably fitting unit LED display blocks containing a plurality of light emitting diodes as a set into a lattice frame in a grid-like arrangement. The unit display blocks are closely mounted, and the case part fits into each square of the lattice frame, and the display part with a built-in light emitting diode that protrudes from the center of the front of the case part is placed in the center of the square of the lattice frame. A long painter's film is arranged at a distance from the lattice frame, is wound up close to the front of the lattice frame, and is provided so that it can be rewound. The unit LED display block is made to selectively emit light to illuminate the corresponding translucent display portion of the film.

Function The present invention has a simple structure in which LED display blocks are removably fitted into a lattice frame and closely mounted to form a full-scale illuminated panel, and a painting board that can be rolled up and rewound is formed with the full-scale illuminated panel. By combining with film, it is possible to support a large number of system displays that meet the above requirements.
It provides an LED display panel, which allows the screen to be changed freely and is closely mounted on a fully illuminated panel.
The LED display block group is adapted to display all changed glyph display patterns within the illumination surface area.

In addition, the LED display block can easily form a dense arrangement of LEDs by fitting the case part into each square of the lattice frame. By arranging them at a distance from each other in the center, it is possible to easily form a crowding state in which there is no mutual light interference and effective cooling, and the LED display blocks can be fitted and removed individually. Moreover, an appropriate gap can be easily formed between the display parts.

Embodiments of the invention Hereinafter, embodiments of the invention will be described in detail with reference to the drawings.
As shown in FIG. 1A, the display panel consists of a lattice frame, two groups of LED display blocks, and a painter's film 3.

As shown, vertical frame 1a and horizontal frame 1b
The substrate is a lattice frame formed by assembling vertically and horizontally to form a large number of squares 1c, and each of the vertical and horizontal frames 1a, 1b
The LED display blocks 2 are fitted into the squares 1c defined by the squares 1c and arranged in a grid pattern to form a full-surface illumination panel 1.

As shown in FIG. 2B, the LED display block 2 consists of a rectangular case portion 2a and a display portion 2b protruding forward from the center of the front surface of the case portion 2a. The display portion 2b is placed in the center of the square of the grid frame and spaced apart from the grid frame, and the display portions are spaced apart from each other in the center of the grid, and the display portion 2b of the case portion 2a is disposed at a distance from the grid frame.
Mounting pieces 2c provided on a diagonal of 45° are filled with screws at the intersections of the frame on the diagonal of each square 1c, as shown in Figure A.

In the same way, each LED display block 2 is connected to each square 1.
c and are closely arranged in a grid pattern.

The display portion 2b is made up of a set of several LED elements and is capable of selectively emitting red, green, yellow, or the like.

On the other hand, the painter's film 3 is a long film made of a transparent synthetic resin such as opalescent polyester, and as shown in FIG. A glyph display pattern 3' consisting of a light display part 3a and a light shielding part 3b is formed, and this is used as a unit glyph display pattern to display multiple units of different glyph display patterns on multiple screens with or without play 4 between each pattern. Form.

In the glyph display pattern 3', portions 3c such as lines that do not require illumination are formed by directly painting the surface of the film with light-colored paint. That is, the non-transparent display portion 3c, such as a line that does not require illumination, is formed by a coating film 3c' formed on the surface of the film.

Also, in the glyph display pattern 3', the parts that require illumination, such as symbols, are not colored using the translucency of the film base material, and are used as translucent display areas, that is, the translucent display areas 3a are made white. As a blank, a light-shielding coating film 3b' is formed on the entire back surface of the film using a fading color paint, and this is used as the light-shielding part 3b. Light display section 3a
shall be.

The formation of the above-mentioned glyph display pattern 3' takes advantage of the characteristics of the film, and if a line change etc. occurs, it can be formed on the surface without tampering with the light-shielding coating 3b' on the back of the film. The line (non-transparent display area 3
c) can be changed. The non-transparent display section 3c
Since the base material of the painting surface is a smooth resin film, it can be easily removed with a solvent such as thinner.

In addition, in the case of modifying or adding the translucent display section 3a, it is easy to cover the non-colored section 3a' on the back side of the film with a light-shielding coating 3b', or to remove the coating film of the additional translucent display section. It is not necessary to tamper with the entire surface of the non-transparent display section 3c.

As mentioned above, it is possible to freely form a graphical display pattern on the film within the screen.

In addition, the coating film 3c' of the non-transparent display part 3c and the light shielding part 3b
This does not preclude the formation of both coating films 3b' on the surface side of the film.

The painter's film 3 is connected to the motor M as shown in FIG.
1 and M2, it is driven and driven in parallel to the front surface of the lattice frame into which the two groups of LED display blocks are fitted, in the vicinity of the full-surface illumination panel 1, and is capable of being wound up and rewound.

That is, the painter's film 3 is placed on one end side of the entire illuminated panel 1.
A motor M1 for winding one end of the painter's film 3 is provided, and a motor M2 for rewinding the other end of the artist's film 3 is provided at the other end.
The artist's film 3 can be wound and rewound by driving one of the motors. For example, when the artist's film 3 is wound by driving the motor M1,
The motor M2 functions as a braking motor, and conversely, when rewinding by driving the motor M2, the motor M1 functions as a braking motor, so that the artist's film 3 can be pulled and run without slack, and the amount of winding or winding can be controlled. Depending on the amount of rewinding, place the necessary screen near either the winding side or the rewinding side in front of the full-scale illuminated panel 1.
That is, it can be developed in front of the display portion 2b group of the LED display block 2 group.

By arranging the painter's film 3 and the full-surface illumination panel close to each other, a communication gap 5 is formed between them 3 and 1 and between the display portion 2b, and a communication gap 5 is formed between them.
An upward air current is generated over the entire surface to exhaust the heated atmosphere and promote good cooling. In addition, the display portion 2b is properly positioned at the center of the grid by fitting the case portion 2a, and is separated from the lattice frame at the center of the grid and is spaced apart from each other.

A painter's film 3, which has been painted as described above, is wound up in close proximity to the front surface of a fully illuminated panel 1 consisting of two groups of LED display blocks as described above, as shown in FIG.
The artist's film 3 is arranged to be rewindable, and the front surface of the artist's film 3 is covered with a see-through plate 6 such as a glass plate or a plastic plate, so that the pictorial display pattern 3' painted on the artist's film 3 is displayed.
is arbitrarily selected, and LED display blocks 2 are densely arranged on the entire illuminated panel 1 from behind the selected screen.
The LED display block 2' corresponding to the translucent display section 3a in the group is selectively made to emit light to perform a predetermined illumination display.

Effects of the invention As explained above, this invention provides a
By removably attaching a group of LED display blocks using a mating method, a full-scale LED illumination panel can be formed extremely easily and used for illumination display on painter's film. In combination with a painter's film that can be rolled up and rewound with a painter's display pattern (display pattern), a variety of multi-color LEDs can be produced by combining the simple blinking of the LED display block and the glyphic display of the painter's film due to its complementary function.
Display is possible.

In other words, the present invention improves the drawbacks of conventional simulated system display panels that cannot keep up with the diversity, and creates a multifunctional and large-area LED display panel that has the advantages of CRT displays without using advanced technology. , can be easily provided by simple mechanical devices.

In addition, according to the present invention, by removably fitting the case part of the LED display block into each square of the lattice frame, it is possible to easily form a dense arrangement of LEDs in each unit group, which is suitable for illumination display of painter's film.
