LED hluav taws xob zaub screen yog tsim los ntawm kaum tawm txhiab-pua pua txhiab ntawm semiconductor lub teeb-emitting diode pixels uniformly teem. Cov ntaub ntawv sib txawv tuaj yeem siv los ua LED pixels ntawm cov xim sib txawv. Tam sim no, feem ntau siv yog liab, ntsuab, thiab daj. Txoj kev loj hlob ntawm xiav thiab ntshiab ntsuab LEDs tau mus txog theem ua tau zoo.
Lub vijtsam LED tuaj yeem tso saib cov lej hloov pauv, ntawv nyeem, thiab cov duab nraaj; Nws tuaj yeem siv tsis tau tsuas yog nyob rau hauv ib puag ncig sab hauv, tab sis kuj nyob rau hauv ib qho chaw sab nraum zoov, thiab muaj qhov zoo sib xws ntawm cov projectors, TV phab ntsa, thiab cov ntxaij vab tshaus LCD.
Yog vim li cas vim li cas LED tau dav muaj nuj nqis thiab tsim kho sai yog sib cais los ntawm nws tus kheej qhov zoo. Hauv kev xaus, cov txiaj ntsig no yog:
High brightness, tsis tshua muaj kev ua haujlwm voltage, tsawg zog noj, miniaturization, lub neej ntev, cuam tshuam tsis kam thiab kev ua haujlwm ruaj khov. Txoj kev loj hlob zeem muag ntawm LED yog qhov dav heev, thiab tam sim no tab tom txhim kho nyob rau hauv cov kev taw qhia ntawm brightness, siab dua huab cua tsis kam, siab luminous ntom, siab dua luminous uniformity, kev cia siab, thiab tag nrho cov xim.
Classification ntawm LED zaub
1. Raws li cov xim puag xim, nws tuaj yeem muab faib ua:
Ib qho xim thawj xim: ib xim (liab lossis ntsuab).
Dual-primary xim zaub: liab thiab ntsuab dual-primary xim, 256-theem greyscale, 65536 xim tuaj yeem pom.
Cov xim puv xim: liab, ntsuab, thiab xiav peb lub ntsiab xim, 256- theem grey-scale puv-xim zaub tuaj yeem pom ntau dua 16 lab xim.
2. Classified los ntawm cov khoom siv:
LED cov zaub: Cov cuab yeej tso saib yog 7- ntu cov raj, uas yog tsim rau ua cov ntxaij vab tshaus, cov paj paj, thiab lwm yam, thiab cov ntxaij vab tshaus digital.
LED dot matrix graphic zaub: Cov khoom siv yog dot matrix zaub module tsim los ntawm ntau yam teeb pom kev zoo sib xws ntawm lub teeb-emitting diodes, haum rau kev ua si cov ntawv nyeem thiab cov ntaub ntawv duab.
3. Muab faib raws lub sijhawm siv:
Sab hauv tsev tso saib: Lub luminous point yog me me, feem ntau Φ3mm--Φ8mm, thiab cov zaub cheeb tsam feem ntau yog ob peb mus rau kaum square meters.
Sab nraum zoov zaub screen: thaj tsam feem ntau yog kaum ntawm square metres mus rau ntau pua square metres, muaj qhov ci ntsa iab, tuaj yeem ua haujlwm nyob rau hauv lub hnub, thiab muaj kev ua haujlwm ntawm cov cua tsis muaj zog, tsis muaj nag thiab tsis muaj dej.
4. Kev faib tawm raws li txoj kab uas hla ntawm lub luminous point:
Sab Hauv Tsev: Φ3mm, Φ3.75mm, Φ5mm,
Sab nraum zoov npo: Φ10mm, Φ12mm, Φ16mm, Φ19mm, Φ21mm, Φ26mm
