LED is the abbreviation of LightEmittingDiode of glow diode English. Have tall brightness, visual sense clarity of ambitious, image, colourful, stability good, power comsumption is low, smooth tall, life grows effect wait for an advantage.
2, the sort of LED indication screen
1, can divide by indication color it is sheet radical color (red or green) , double base color (gules, green) , 3 base color (gules, green, blue) .
2, can divide the Wen Bing that it is a graph, synchronous screen, prices to display screen by indication function (include screen of exchange rate of negotiable securities screen, interest rate, factory to look board, safe card)
3, divide by glow material:
① module (use at indoor screen) : By glow dot diameter can divide 5.0mm of 4.8mm of 3.75mm of the 3.0mm that it is Ф , Ф , Ф , Ф to wait.
② module reachs canal resembling element (use at) of the screen outdoor: The span that press a point can be divided wait for PH8mm, PH10mm, PH16mm, PH20mm
③ number is in charge of (use at prices to show screen) : The span that press a point can be divided it is 1.2 inches, 1.5 inches, 1.8 inches, 2.3 inches, 3 inches, 4 inches wait.
4, divide by use environment: Can divide for the indoor screen, screen outdoor and half outdoors screen.
3, the action of LED indication screen and application
1, LED indication screen reachs TV, kinescope to wait with indication character, image, animation, prices. Have a variety of editors and broadcast a function.
2, LED indication screen applies extensively at all trades and professions such as Wu of finance, duty, electric power, traffic, telegraphic, medical treatment, wholesome system and government organization, stadium canal, industrial and mining enterprises.
4, of LED indication screen form reach its sketch map
By LED + of body of indication screen screen controls structure of frame of peripheral equipment + of + of systematic + relevant software and adornment construction.
1923, luosaifu (Lossen.o.w) studying semiconductor SIC from time to tome the bright in the P-N knot of foreign matter blasts off, excogitated glow diode (LED: LightEmittingDiode) , unvalued all the time. As the rapid development of electronic industry, in 60 time, indication technology gets developing quickly, people excogitates PDP laser to show plasma shows board, LED of diode of LCD LCD, glow, report is sent become angry a variety of technologies such as indication EPID of indication ECD, electrophoresis. As a result of semiconductor make and perfect, glow diode already took dominant place in solid monitor with each passing day. LED is taken seriously extensively and get developing quickly, because itself has activity, a lot of advantages,be. For example: Brightness depress of report of tall, job, power comsumption is small, easily compositive, drive simple, life is long, impulse withstand and performance is steady, its development perspective is very wide. Shining higher forward at present degree, taller weatherability and uniformity of hair optical density, glow, panchromatic changes development.
