Ib qho ntawm qhov zoo nkauj ntawm kev siv tshuab yog tias nws tau coj peb cov duab OLED. Yog tias koj nyob hauv kev ua lag luam rau cov zaub niaj hnub thiab xav kom nws muaj cov yam ntxwv uas koj xav tau, ces koj yuav tsum tshawb xyuas OLED cov lus qhia. Hauv lub sijhawm nrawm nrawm no, nws tsim nyog paub txog qhov zoo ntawm OLED cov lus qhia.
OLED yog dab tsi?
OLED yog lub ntsiab lus ntawm "organic light-emitting diode". Lwm lub npe yog "organic electroluminescent diode". Nws emits lub teeb ncaj qha los ntawm hluav taws xob, tsis zoo li cov kev cai ntawm emitting lub teeb los ntawm cua sov lub filament nrog hluav taws xob. OLED cov lus qhia yog tsim los ntawm nyias txheej ntawm iav, yas thiab cov organic molecules tshwj xeeb uas cuam tshuam rau cov nqi hluav taws xob thiab tsim kom muaj cua sov tsawg. Kov lub OLED zaub yog yuav luag tsis sov, uas txuag tau ntau lub zog, uas yog ib qho kev txhim kho loj dua li cov khoom siv hluav taws xob siv CRT yav dhau los.
Keeb kwm ntawm OLED
Kev tshawb pom ntawm OLED technology niaj hnub tuaj yeem taug qab mus rau xyoo 1987. Lub sijhawm ntawd, ob tus kws tshawb fawb los ntawm Donman Kodak, Steven Van Slyke thiab Ching Tang, nrhiav tau qee cov organic uas tuaj yeem tawm lub teeb ntawm qhov hluav taws xob tsawg. Thaum ntxov li xyoo 1960, qhov kev tshawb pom ntawm kev ncua fluorescence tau ua rau txoj kev yug me nyuam ntawm OLED. Txawm hais tias cov ntaub ntawv organic thaum ntxov yuav tsum muaj qhov hluav taws xob siab kom tawm lub teeb, Kodak cov kws tshawb fawb tau ua tiav hauv kev ua tiav cov fluorescence ntawm qhov hluav taws xob tsawg.
Cov kws tshawb fawb thawj zaug tau tsim OLEDs nrog lub ntsej muag daj-ntsuab, tom qab ntawd lub txiv kab ntxwv-liab spectrum, thiab thaum kawg kov yeej txoj cai sib txawv ntawm lub zog kom ua tiav cov xim liab diode emission. Tom qab ntawd, raws li cov thev naus laus zis tau txhim kho, cov duab OLED tshiab xws li AMOLED (active matrix organic teeb-emitting diode) tshwm sim.
Cov Cheebtsam tseem ceeb ntawm OLED zaub
Lub plawv ntawm OLED zaub yog OLED emitter. Nws yog ib qho organic tivthaiv uas tawm lub teeb thaum siv hluav taws xob. Lub hauv paus qauv muaj xws li ib txheej ntawm cov khoom ntawm lub anode thiab cathode. Cov khoom siv niaj hnub OLED muaj ntau txheej txheej los txhim kho kev ua haujlwm ntev thiab kev ua haujlwm, tab sis cov haujlwm tseem ceeb tseem zoo ib yam. OLED panels yog tsim los ntawm lub vaj huam sib luag pem hauv ntej, lub vaj huam sib luag tom qab, electrodes, txheej encapsulation, thiab substrate. Qhov no system yog heev rhiab heev rau ya raws thiab oxygen, yog li lub encapsulation txheej yog heev complex.
Substrate
Lub hauv paus ntawm OLED cov lus qhia yog iav lossis yas substrate, cov khoom pob tshab uas muab qhov chaw ruaj khov rau lwm cov khoom.
Organic Txheej
Ntau txheej ntawm cov ntaub ntawv organic tau muab tso rau ntawm lub substrate, suav nrog:
Emitting txheej: Muaj cov organic molecules uas emit lub teeb nyob rau hauv hluav taws xob stimulation.
Qhov chaw thauj txheej:thauj cov nqi zoo (qhov) mus rau txheej emitting.
Electron thauj txheej: thauj cov nqi tsis zoo (electrons) mus rau txheej emitting.
Transparent Conductive Txheej
Cov txheej no yog nyob rau ntawm ob sab ntawm cov organic txheej thiab ua raws li pob tshab electrode, tso cai rau tam sim no ntws mus rau hauv thiab tawm ntawm cov organic txheej.
Encapsulation Txheej
Txhawm rau tiv thaiv cov txheej txheem organic tsis yooj yim los ntawm ya raws thiab oxygen, txheej txheej encapsulation feem ntau yog siv rau saum, uas muaj cov khoom thaiv kev tiv thaiv ib puag ncig los ntawm kev cuam tshuam cov txheej txheem organic.
Qhov zoo thiab qhov tsis zoo ntawm OLED zaub
Qhov zoo
- Ultra-nyias tsim:OLED zaub yog nyias dua li LCD thiab LED zaub.
- Flexibility:Lub substrate ntawm OLED tuaj yeem yog yas, ua rau nws yooj yim dua.
High brightness: Lub teeb-emitting txheej yog ci dua thiab tsis xav tau kev txhawb nqa iav.
Tsawg zog noj:Tsis tas yuav muaj teeb pom kev zoo, kev siv hluav taws xob qis dua, thiab nws tsim nyog rau cov khoom siv roj teeb.
Yooj yim rau siv:Nws tuaj yeem ua rau ntau qhov loj thiab txhawb nqa cov ntaub ntawv yas, uas yooj yim rau kev nthuav dav.
Qhov tsis zoo
Xim teeb meem:Blue organic cov ntaub ntawv muaj lub neej luv luv.
High manufacturing nqi:Cov dej noo tuaj yeem ua rau lub cev OLED puas.
OLED Daim Ntawv Thov
OLED thev naus laus zis tau ua tiav qhov tseem ceeb hauv ntau yam kev siv:
TV loj:OLED TVs paub txog lawv cov duab zoo heev.
Digital Signage:Siv los nyiam cov khw muag khoom, khw noj mov, tshav dav hlau, thiab lwm yam.
Video phab ntsa:Lub phab ntsa loj video tsim los ntawm ntau lub OLED cov lus los tsim kom muaj kev paub zoo.
Heads-up Display:siv hauv maus taus kaus mom hlau los muab cov ntaub ntawv tsim nyog yam tsis muaj kev cuam tshuam qhov muag.
Pob tshab OLED:rau automotive displays thiab augmented reality tsom iav.
Thaum twg thiaj xaiv OLED zaub rau kev lag luam?
OLED cov lus qhia muab kev pom zoo zoo rau kev lag luam kev lag luam uas qhov kev pom zoo nkauj yog qhov tseem ceeb. Nov yog qee qhov kev txiav txim siab tseem ceeb:
• Cov ntsiab lus siab:OLED cov lus yog qhov kev xaiv zoo tshaj plaws thaum cov duab daws teeb meem siab, cov yeeb yaj kiab, lossis cov duab yuav tsum tau tso tawm.
•Kev pom dav dav:OLED cov lus qhia muab cov duab sib xws, kom ntseeg tau tias cov ntsiab lus raug nthuav tawm thaum pom los ntawm ntau lub kaum ntse ntse.
•Nyias thiab lub teeb tsim:OLED cov lus yog nyias thiab sib zog dua li cov khoom siv LCD, ua rau lawv tsim nyog rau cov ntawv thov qhov chaw txwv lossis tsim kom zoo nkauj.
•Tsawg zog noj:OLED cov lus pom muaj zog ntau dua li cov duab LCD, txo cov nqi khiav lag luam thiab kev cuam tshuam ib puag ncig.
Yog tias koj daim ntawv thov kev lag luam xav tau cov duab zoo, pom dav dav, thiab tsim kom zoo nkauj, OLED zaub yuav yog qhov kev xaiv zoo tshaj.
Qhov txawv ntawm OLED Vs LED / QLED zaub
Cov khoom siv coj ua LED yog ua raws li cov thev naus laus zis LCD, lub sijhawm sim qauv. Cov ntxaij vab tshaus LCD muaj ib daim phiaj nyias ntawm cov transistors uas ua haujlwm siv cov khoom siv lead ua me me. Cov txheej txheem no suav nrog kev tswj hwm ntawm qhov tsaus thiab ci pixels, tab sis qhov tseeb lub teeb tawm los ntawm kev cia ntawm LEDs. Txoj hauv kev zoo tshaj plaws los ntsuas lub vijtsam LCD yog siv lub teeb ci LED, uas tso cai rau qhov sib txawv ntau dua thiab zoo dua lub vijtsam dimming, ua rau cov zaub zoo dua li yav dhau los. OLED technology mus ib kauj ruam ntxiv, muab kev tiv thaiv qhov muag thiab tsis ua rau pom kev qaug zog.
Kev tsim kho ntawm QLED cov lus qhia txawv heev ntawm OLED cov lus. QLED cov lus siv quantum dots, uas tsim lub teeb thaum siv hluav taws xob, zoo ib yam li OLED. Tab sis QLED hloov lub teeb xiav nws tau txais mus rau hauv lub teeb dawb, uas ua tiav los ntawm kev siv liab thiab xiav quantum dots. QLED cov duab ci dua, tab sis kuj tseem kim dua OLED thiab tseem nyob rau theem pib ntawm kev txhim kho. Hauv qhov sib piv, OLED cov lus qhia yog tus kheej luminous, tso saib lawv cov xim, thiab tsis tshua kim. LED zaub, ntawm qhov tod tes, yog ib lub vaj huam sib luag ua los ntawm lub teeb-emitting diodes, thiab feem ntau yog siv hauv cov ntawv tshaj tawm thiab cov paib.
