Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention lights up light emitting diodes arranged arbitrarily to display characters, characters, etc.
The present invention relates to a device that displays display patterns such as numbers and graphics.

"Prior Art" In recent years, instead of flap boards and 7-segment display devices, display boards with light-emitting diodes (hereinafter referred to as LEDs) arranged in a matrix have been used to display text information and graphic patterns, including kana-kanji, in a variety of ways. Electric display devices that display images are becoming widespread.

These devices include a control section consisting of a large-scale microcomputer, and display by selectively lighting up each LED based on display pattern software and display schedules stored in memory.

[Problems to be Solved by the Invention] This type of electronic display device can express far more information than previous devices, considering the types of character patterns that can be displayed. If display variations such as various scrolls are added to this, the frame will further expand, making it suitable as a display means.

However, on the other hand, as mentioned above, it requires a control device such as a large-scale microcomputer, an LED driving means, a large number of LED elements, a display data input system, etc., which increases the price of the entire device.
Although it was popular among companies and relatively large stores, it was difficult to spread to small stores and other areas close to general users.

Therefore, if you look for a device that focuses on low price, you will end up with a device that displays fixed information or cannot display graphics. There was no suitable display device with a display function.

Therefore, an object of the present invention is to provide an LED lighting method and device that does not require a complicated control device or LED driving device, is inexpensive, and can freely display a desired pattern.

[Means for Solving the Problems] The present invention has been made to address the above problems.
A light emitting diode comprising a plurality of conductive mats connected to a power supply and insulated from each other, and a plurality of connection terminals corresponding to each layer of the conductive mat and electrically connected only to the corresponding layers. The light emitting diode has a structure in which the connection terminal of the light emitting diode is inserted into any position of the conductive mat to turn on the light.

[Example] Hereinafter, the embodiment will be described in detail based on the drawings.

FIG. 1 is an explanatory diagram showing an LED element according to an embodiment of the present invention. Reference numeral 1 designates an LED capable of emitting light in three colors, and includes a light emitting part 4 made of a red light emitting element 2 and a green light emitting element 3 molded with transparent resin, and three connection terminals 4 connected to both light emitting elements.
, 5.6. The three connection terminals have pointed tips and are coated with an insulating material 7, and each has a conductive portion 4a5 at a different height for electrical contact.
a, 6a. Therefore, if a current is passed through the conductive parts 4a and 5a, the red light emitting element 2 will emit light, and similarly the red light emitting element 2 will emit light.
When a current is passed through 5a and 5a, the green light emitting element emits light. Furthermore, when all the connection terminals are energized, both light emitting elements emit light, and the overall color becomes orange, making it possible to obtain three colors of emitted light.

Next, FIG. 2 is an explanatory diagram showing a cross section of a display board to which LEDs are fixed. 8a is a longitudinal cross-sectional view of a display board, which is constructed by stacking a plurality of conductive mats, such as conductive rubber, in a layered manner. 9.10.11 is the conductive mat, in this case 3 corresponding to the number of connection terminals of the LED.
It has a three-layer structure using two mats. The conductive mats are stacked with an insulating layer in between, and in the figure, 12 and 13 are made of a material that performs an insulating function and allows the LED connection terminal to be inserted or removed.

The conductive mat 9, which is the uppermost layer, is a transistor T r
The conductive mat 10 connected to the DC power source 12 via 1 and in contact with the insulating layer 12 on both sides is grounded at 14. The remaining conductive mat 11 at the bottom layer is connected to the DC power supply 13 via the transistor Tr2 similarly to the conductive mat 9 described above. Tri again.

The base of Tr2 is connected to the drive ICl3 which is connected to the shift register ICf, and is applied to the drive ICl3 to switch the conduction of electricity to the conductive mats 9 and 11.

Next, Figure 3 shows the state of 7f with the LED inserted into the display board.
It is a cross-sectional explanatory view showing J.

As shown in the figure, when the connection terminal of the LED is completely inserted into the display board 8a, the conductive part 4a is attached to the conductive mat 9.
A is electrically connected to the conductive mat 10, and 6a is electrically connected to the conductive mat 11, forming a closed circuit. Therefore, the drive IC
When the output signal of 13 is applied to the base of Tri, the conductive part 4a of the LED is transmitted from the power supply 12 through the conductive matrix 9.
A current flows through 5a, and as a result, the LED emits red light.

On the other hand, when the output signal of the drive IC is applied to the base of T r 2, the power source 14 and the conductive mat 11 are connected, current flows from the conductive part 6a to 5a, and the LED emits green light. Furthermore, when output signals are applied to the bases of both Tri and Tr2, as described above, both red and green colors are mixed to emit orange light.

As described above, the LEDs inserted into the display board are turned on. However, in the present invention, a plurality of display boards of the same size are connected together, with the display board 8a as the minimum unit, to form one display board. It consists of Figure 4 shows this.

8 is the smallest unit display board (8a, 8b, 8c).

8d...) is a display board. 16 is a drive circuit 16a that actually performs switching of each display board;
The drive board is composed of 16b, 16c...16f"'C, and each drive circuit is composed of elements such as the transistor and resistor. 17 is a driver controller that drives the drive board, and
Consists of. Reference numeral 18 indicates a display specifying means (described later) for specifying the drive method (switching order) of the display board on the display board, the display method of the emitted light color of the LED, etc., and 19 corresponds to the display specifying information given by the display specifying means, It is a control means for controlling the driver controller.

Next, referring to FIG. 5, an input device serving as a display specifying means will be explained.

21 is a liquid crystal panel (hereinafter referred to as an LCD panel), 25a
is a green designation key, 25b is a red designation key, 25c is an orange designation key, 26 is an instruction clear key, 21 is a set key, and 28 is a memory key. In the input device composed of these, the display method is specified according to the flowchart shown in FIG.

When you turn on the power by operating the power key 23, (1), L
A display appears on the CD screen to select the input type: pattern change, display sequence creation, or display change (2
). If you choose to create a pattern, follow the steps below.

First, select the display mode (3). There are two types of display modes to choose from: ``blink mode'' and ``standard mode.'' When you select blink mode, for example, the LED
When lighting up each display board in order from the left, the board does not continue to emit light, but moves to the right (in terms of visual recognition) while board 1 is in a shepherding position. Therefore, when the right end is reached, all the display boards are not lit, and only the rightmost board is lit. In other words, this is a mode in which the display of the previous stage is not continued. After selecting the display mode, enter the lighting order of each display board using the number keys and tongue keys (4).

In that case, the numbers correspond in order from the leftmost display board. If you want to light up one board at a time, press the return key each time you press the corresponding number key. If you want to light up multiple boards at the same time, press the return key each time you press the corresponding number key. After pressing the corresponding number keys, press the return key and press the set key to finish inputting the lighting order. Next, specify the number corresponding to the display board and the emission color using any of the keys 25a, 25b, and 25C, and press the set key to specify the emission color of each display board (5). Then, input the pattern number of the pattern created above (6), press the memory key 28 to register it (7), select whether to execute the pattern (8), and complete the pattern creation.

Next, when display sequence creation is selected in step (2), the following operations are performed.

First, enter the pattern numbers of the already registered patterns in order, and finally press the set key to create a display sequence that is a combination of different patterns (
11). Then, input the sequence number of the created sequence (12) and press the memory key 28 to register it (13). Thereafter, the user selects whether to execute the created display sequence by changing the sequence currently being executed on the display board (14), and ends the pattern creation.

Further, when display change is selected in step (2), a pattern number or sequence number to be adopted in place of the sequence or pattern currently displayed is inputted (17), and the set key is pressed.

Then, the display on the display board will be changed to the new one.

In addition, although the above embodiment describes a three-color emitting LED, a monochromatic emitting LED may also be used. In that case,
Two conductive mats may be used to create a two-layer structure with an insulating layer sandwiched between them. Further, the display designation means may not be provided, and the display may be made into a single function having only several types of simple display methods, thereby further reducing costs.

[Effects of the Invention] As explained above, according to the present invention, there is no need for a control device using a large-scale microcomputer, an LED driving means, a large number of LED elements, or a complicated display data input system. A low-cost display device can be realized. Moreover, the display information does not become fixed or the graphics cannot be displayed, and the desired display pattern can be easily displayed by simply replacing the LED elements on the display board by hand, regardless of whether the device is running or not. I can do it. Therefore, it is a suitable LE that can freely display desired patterns at a low price that is affordable to general users.
The lighting display device D can be realized.
