Enter the electronics to P areas, in a few micrometers near PN junction respectively with the electronics and the hole-recombination in P areas in N areas, produce spontaneous radiation
Fluorescence.Gallium arsenide diode glows, gallium phosphide diode green light, silicon carbide diode Yellow light-emitting low temperature, gallium nitride diode hair
Blue light.Divide Organic Light Emitting Diode OLED and inorganic light-emitting diode LED again because of chemical property.LED is used as light source to be had
Following plurality of advantages：1. safe：LED uses low-tension supply, is a power supply more safer than using high voltage power supply, particularly suitable
In public place.2. efficient：LED consumed energies relatively reduce 80% or so with the incandescent lamp of light efficiency, and it is left to reduce 40% compared with electricity-saving lamp
It is right.3. strong applicability：LED volume very littles, each unit LEDs small pieces are the squares of 3-5mm, it is possible to be prepared into various shapes
The device of shape, and it is adapted to variable environment.4. stabilization：After using 100,000 hours, light decay is only initial 50% to LED.5.
Response is fast：Compared to the response time of incandescent lamp, the response time of LED is nanosecond.6. environmental protection：LED is free of poisonous metal
Mercury etc..7. color category is various：LED can realize that reddish yellow is green conveniently by the band structure and energy gap of adjustment material
Blue Curacao is multicolor luminous.8. cheap：With industrial expansion, the price of LED is more and more popular.
With Chinese society rapid development of economy, the application of LED is changed into large scale array via exclusive use to be made
With being shown including advertisement, video playback, lamp light landscape etc., particularly in urban traffic information display field, using very wide
It is general.But the extensive LED clusters for being used at present show and problems with are still present, first, waste the energy；Secondth, strong
Under strong sunlight, display effect is still not fully up to expectations；3rd, do not possess vocality；4th, video playback excuse versatility
Difference；5th, network remote communication function is lacked；6th, display image authentication function is lacked.For this drives the invention provides one kind
Dynamic and control LED array system and method, for solving disadvantages mentioned above.
The content of the invention
