Yuav ua li cas ib qho OLED emits teeb?

May 03, 2017

Yuav ua li cas qhov no nyuaj ntawm khaubncaws sab nraud povtseg ua lub teeb?


  1. Yuav kom ua ib qho kev OLED teeb li, peb tsuas muab ib tug voltage (tej zaum sib txawv) thoob plaws lub anode thiab cathode.

  2. Raws li cov hluav taws xob pib ntws, lub cathode tau txais electrons los ntawm lub hwj chim qhov twg los thiab cov anode loses lawv (los yog nws "tau txais qhov," yog hais tias koj xav mus saib nws hais tias txoj kev).

  3. Tam sim no peb muaj ib qhov teeb meem nyob qhov twg lub ntxiv electrons yog ua lub emissive txheej tsis zoo them (zoo li lub n-hom txheej nyob rau hauv ib tug hlws ris diode), thaum lub conductive txheej yog kab zoo them (zoo li p-hom ntaub ntawv).

  4. Zoo qhov yog ntau npaum li cas mobile tshaj tsis zoo electrons kom lawv dhia hla tus ciam ntawm lub conductive txheej mus rau emissive txheej. Thaum muaj ib lub qhov (ib tug tsis muaj electron) raws li ib tug electron, ob yam rho tawm thiab tso ib nyuag tawg ntho ntawm lub zog nyob rau hauv daim ntawv ntawm ib tug particle ntawm lub teeb-ib photon, nyob rau hauv lwm yam lus. Qhov no yog hu ua recombination, thiab vim hais tias nws yog tshwm sim muaj ntau zaus ib tug thib ob lub OLED ua tas mus li lub teeb kom ntev li ntev raws li qhov tam sim no yuav ntws.

Peb yuav ua tau ib tug OLED tsim kob teeb los ntawm kev ntxiv ib tug dawb lias lim rau hauv peb yas nyuaj cia li hauv qab lub iav los yog yas sab saum toj los yog hauv qab txheej. Yog hais tias peb muab tso rau txhiab tus liab, ntsuab, thiab xiav OLEDs tom ntej no mus rau ib lwm thiab hloov lawv rau hauv thiab tawm ntawm nws tus kheej, lawv ua hauj lwm ib yam li cov pixels nyob rau hauv ib tug pa LCD screen, li ntawd, peb yuav ua tau txoj, hi-kev daws teeb meem dawb lias duab.
