Description

LED display system with real-time remote monitoring function {LED ELECTRIC BULLETIN BOARD SYSTEM HAVING REAL-TIME MONITORING FUNCTION}

The present invention relates to an LED signboard system, and more particularly, to a LED signboard system that can implement a real-time remote monitoring function by including a sensing board that can detect the internal state in the LED signboard.

In order to provide information to the public in places where a lot of people gather, for the purpose of publicity and advertising, or in places where information such as history waiting rooms, sports grounds, roads, or other information is needed, such as public information, etc. Bulletin boards are constructed to express various messages.

For example, boarding stations where passengers wait for getting on and off public transportation such as subways require bulletin boards that can display train operation information such as arrival time and destination of the next vehicle to arrive. Since should be able to immediately display the situation that changes over time, it is preferable that the description is formed in a structure that can be easily changed according to the situation.

Therefore, in the past, a mechanical structure in which a thin plate with a destination or the like is automatically replaced, and a bulletin board having a simple structure such that the contents are lit when the train comes in has been used, but in recent years, when electronic technology has advanced rapidly. In addition, the display technology using electronic technology has been greatly improved, and thus, an electric bulletin board (hereinafter referred to as an electric bulletin board), which is easy to change a displayed message, has been widely distributed. Tend to be.

The display unit of the signboard is composed of small light emitting units that can emit light. The LED signboard is composed of light emitting diodes (LEDs), and the LED at a specific position constituting the display unit. By controlling the light emission pattern, specific characters, shapes, images, and the like can be displayed.

LED uses the light emitting phenomenon generated when voltage is applied to the semiconductor, that is, the electroluminescence, and since the discovery of the high luminous efficiency at the p-n junction, the research has been actively conducted and it has been put into practical use in the 1970s.

As a suitable material condition for manufacturing LED, firstly, the emission wavelength should be near the visible or infrared region, secondly, the luminous efficiency is high, and thirdly, the pn junction can be manufactured. Gallium GaAs, gallium phosphide GaP, gallium-arsenic-phosphorus GaAs1-x Px, gallium-aluminum-arsenic Ga1-xAlxAs, indium phosphide InP, indium-gallium-phosphorus ln1-xGaxP, etc. Is being used.

The light emitting mechanism of LED can be largely classified into the recombination of free carriers and the recombination in the impurity emission center. The recombination of free carriers mainly results in light emitting diodes in the visible region, whereas in the impurity emission center. By the recombination of is dependent on the type of impurities added to the semiconductor.In the case of gallium phosphide, the emission of zinc and oxygen atoms is red (wavelength 700 nm) and the emission of nitrogen atoms is green (wavelength 550 nm). to be.

Such LEDs can be manufactured in a small size, have a long lifespan, and because electrical energy is directly converted into light energy, the response speed is fast, the power is low, and the efficiency is high, and various colors can be realized. Therefore, it has a great advantage of satisfying various performances required as light emitting units of an electric signboard at the same time. Recently, LED TVs have been manufactured in response to the rapid development of LED-related technologies.
