Description
Technical field
The present invention relates to a kind of LED display and its process for making, in particular, it is related to a kind of high intensity to resist
Impact LED display and its process for making.
Background technology
LED display（LED display）：A kind of flat-panel monitor, is made up of LED module panel small one by one.
LED, light emitting diode（Light emitting diode abridge）.It is one kind by controlling semiconductor light emitting
The display mode of diode, by gallium（Ga）With arsenic（As）, phosphorus（P）, nitrogen（N）, indium（In）The diode that is made of compound, work as electricity
Visible ray can be given off when son is with hole-recombination, thus can be used to be made light emitting diode.Conduct refers in circuit and instrument
Show lamp, or composition word or numerical monitor.Gallium arsenide phosphide diode glows, gallium phosphide diode green light, carborundum two
Pole pipe Yellow light-emitting low temperature, indium gallium nitrogen diode blue light-emitting.
LED display is generally used to the various information such as display word, image, video, video signal.
The glow color and luminous efficiency of LED are relevant with the material and technique that make LED, and lamp ball just starts to be full blue light
, behind add fluorescent material, according to the different needs of user, adjust out different photochromic, it is widely used have red, green, blue,
Huang Si kinds.Because LED operation voltage is low（Only 1.2 ~ 4.0V）, can actively light and have certain brightness, brightness can use voltage again
（Or electric current）Regulation, itself again impact resistance, anti-vibration, long lifespan（100000 hours）, so in large-scale display device, still
It is equal to LED display modes without other display modes.
The display screen made as a pixel that the LED wafer or fluorescent tube of red and green are put together calls three colors or biradical
Color screen, puts as a display screen for pixel three kinds of LED wafers of red, green, blue or fluorescent tube three primary colours screen or full-color together
Screen.It is called monochromatic or single primary colours screen if only a kind of color, the Pixel Dimensions of LED screens are usually 1.5-12 in make-up room
Millimeter, usually encapsulates integrally using several LED dies that can produce different base colors, and the Pixel Dimensions of outdoor LED screens are generally
6-41.5 millimeters, each pixel is made up of several various monochromatic LEDs, and common finished product claims pixel cylinder, and double-colored pixel cylinder is general
By 2 red 1 it is green constitute, three color pixels cylinder blue is constituted with 1 red 1 green 1.
No matter monochromatic, double-colored or three color screens are made with LED, each LED's of image pattern of wants pixel to be shown is luminous
Brightness all must be able to regulation, and the fine degree of its regulation is exactly the tonal gradation of display screen.Tonal gradation is higher, the image of display
Finer and smoother, color is also abundanter, and corresponding display control program is also more complicated.The image of general 256 grades of gray scales, color mistake
Cross very soft, and 16 grades of coloured images of gray scale, color transition boundary line is fairly obvious.So, color LED screen currently will
Ask and make 256 grades to 4096 grades gray scales.
Why in widespread attention LED is and is developed rapidly, be had the advantage that with itself it is inseparable.This
A little advantages sum up and are：Brightness is high, operating voltage is low, small power consumption, maximization, long lifespan, impact resistance and stable performance.LED
Development prospect it is extremely wide, just towards more high brightness, more high weather resistance, luminous density higher, higher luminous uniform
Property, reliability, panchromaticization direction are developed.LED display be widely used in stadiums, business application, bank, card Securities, postal service,
Harbour, market, station, postal service, telecommunication, office, monitoring, school, dining room, hotel, amusement, etc. different outdoor locations advertisement a surname
Pass, Russian Games for university students UNILUMIN is smooth fine and smooth using Umesh25 building screen live events picture within 2013.
Static scanning technology uses static latch scan mode, high-power driving to fully ensure that luminosity is automatically bright
Degree regulation has automatic brightness adjusting function, optimal result of broadcast ..LED display screens can be obtained under different lightness environment and is being protected
While having brightness, drawback is there is also, be exactly that, on rainy day, LED display drenches by rainwater, the eyes of people are near for a long time
Distance will be easy to induce eye illness against display screen, situation about dropping tears, this light source pollution, LED display conduct occur
Green technology should need more to fill part in view of light to the influence in terms of the spirit of people, should not excessively pursue brightness.
Import large scale integrated circuit is used comprehensively, and reliability is greatly improved, and is easy to debugging maintenance.
LED display now on the market is all more fragile, anti-fight poor performance, meeting during by more big external impacts
There is situations such as damaging, it is fairly cumbersome.
