Led advertising screen principle
In 1907 Henry Joseph Round first observed electroluminescence in silicon carbide. The first commercial diode was made in 1960.The emitting diode, an abbreviation of the English light emitting diode, is basically an electroluminescent semiconductor material that is placed on a lead bracket and sealed with epoxy resin to protect the internal core wire, so the LED has a good seismic performance.
The core of led is a chip composed of p-type semiconductor and n-type semiconductor. There is a transition layer between p-type semiconductor and n-type semiconductor, which is called p-n junction.In PN junction of some semiconductor materials, the combination of minority carriers and majority carriers injected will release the excess energy in the form of light, thus directly converting electrical energy into light energy.PN junction plus reverse voltage, a few carriers are difficult to inject, so no light.This kind of diode that USES injection electroluminescence principle to make is called LED, common name LED.When it is in a positive working state (that is, add a positive voltage at both ends), when the current flows from the LED anode to the cathode, the semiconductor crystal will emit different colors of light from ultraviolet to infrared, and the intensity of light depends on the current.
Led advertising screen features
LED advertising screen is mainly used in indoor large area of commercial advertising and venue, lobby, hotel, etc.
(1) high density, high definition display;
(2) the light-sensitive control system can automatically adjust the brightness of the display screen according to the changes of indoor and outdoor light, which is energy-saving and environmentally friendly, greatly reducing your operating costs and making it more acceptable to the audience;
(3) the product launches a low-power solution, which can save 1/3 of the energy when the display screen is running, further greatly reducing your operating costs;
(4) with high refresh rate and high grayscale, LED advertising screen images are more realistic and meet the requirements of high visual quality for commercial use;
(5) with the function of brightness and point-by-point color correction, LED advertising screen can provide richer images and meet the requirements of high visual quality for commercial use;
(6) the advertising content on the screen can be changed at any time, and different advertisements can be displayed for different customers around the clock;
(7) with dual network cable hot backup function, two computers control one screen at the same time, when one computer has a problem, the other computer automatically replace, to ensure the normal work of the display screen;
(8) all the display information can be controlled by remote network, and the screen information can be easily changed by mouse click operation, so as to realize the clustering of advertising display network in cities and regions;
(9) support network control function, so that you can control the display screen of several cities in one place, and change the content you want to play at any time;
(10) with the multi-function card equipped by mingrui optoelectronics, the display screen can be switched on and off at any time with software or manually to realize the unattended function.
