Teeb Meem Lub Ntsiab ntawm OLED Zaub Technology
Jul 16, 2018
Nrog rau kev nthuav dav ntawm kev tshawb fawb thiab kev siv tshuab, kev siv cuab yeej hluav taws xob ntawm cov khoom vaj khoom tsev hauv plhaus tiaj yog kev txhim kho, ua raws li kev sib tw, cov kws ua haujlwm tsim kev twv, yav tom ntej, OLED panels yuav hloov tag nrho cov koob panels, -panel TVs. Piv nrog CCFL, LED muaj qhov zoo nyob rau hauv kev ua yeeb yam. Yog li, qhov zoo ntawm OLED yog dab tsi? Niaj hnub no, peb tham me ntsis txog txoj cai tso tawm OLED zaub technology.
Tsis zoo li cov lus qhia hauv LCD, OLED tso tawm tshuab tshem tawm cov kev xav tau rau cov nraub qaum thiab siv cov organic coatings heev thiab cov iav substrates uas taws thaum tam sim no kis los ntawm. Tsis tas li ntawd, qhov screen screen OLED yuav ua tau nrig thiab thinner, muaj lub qhov rooj loj dua, thiab tuaj yeem txuag tau lub zog.
Tus qauv ntawm OLED yog tsim los ntawm cov thev plaub, cov khoos kas semiconductor hauv indium tin oxide (ITO) txuas rau qhov hluav taws xob zoo ntawm hluav taws xob, thiab lwm cov hlau cathode, uas yog sandwiched rau hauv ib lub qauv nyuaj. Tag nrho cov txheej txheem muaj xws li ib lub qhov kev thauj (HTL), ib lub teeb emitting txheej (EL), thiab ib qho hluav taws xob xa hluav taws (ETL). Thaum lub hwj chim muab rau ib qho kev tsim nyog, lub qhov zoo thiab lub cathode nqi them tag nrho hauv lub teeb-emitting txheej tsim teeb pom kev, thiab peb lub ntsiab xim ntawm liab, ntsuab, thiab xiav RGB raug tsim tawm raws li daim ntawv tsim los ua ib qho xim yooj yim. Cov yam ntxwv ntawm OLEDs yog self-illuminating. Tsis zoo li TFT LCDs, uas yuav tsum tau kev txhawb zog, lawv muaj cov visibility siab thiab ci ntsa iab, ua raws li kev tsis tshua muaj qhov tsis zoo thiab kev siv hluav taws xob txuag kev ua haujlwm, ntxiv rau cov lus teb ceev ceev, lub cev nyhav, thin thickness, cov qauv yooj yim, tus nqi qis, thiab lwm yam. feem ntau cov khoom cog ntawm lub xyoo pua 21st.
Kom illustrate tus configuration OLED, txhua lub chav hauv OLED yuav muab piv rau tus hamburger, thiab cov khoom luminescent yog cov zaub qhwv ntawm lawv. Cov kab xev ntawm txhua tus OLED tuaj yeem tswj tau tsim peb xim sib txawv ntawm lub teeb. Zoo ib yam li LCDs, OLEDs kuj tseem ua haujlwm thiab muaj lub luag haujlwm. Lub xov tooj ntawm tes xaiv los ntawm kab thiab kem chaw nyob hauv hom passive yog lit. Nyob rau hauv lub hom phiaj, muaj ib zaj duab xis transistor (TFT) tom qab hauv chav tsev OLED, thiab lub teeb emitting yog lit nyob hauv TFT tsav tsheb. Passive OLEDs yog cov hwj huam ntau, tiam sis cov nquag OLEDs tso saib zoo dua.
Qhov zoo ntawm OLED yog tias nws yog nyias thiab lub teeb, thiab nws cov tuab yog tsuas yog ib feem-peb ntawm cov LCD; vim hais tias nws yog solid-state qauv, nws muaj kev kawm zoo dua seismic thiab tsis ntshai poob; qhov pom lub kaum loj yog loj, thiab daim duab tseem tsis distorted txawm tias thaum pom hauv ib lub qhov loj saib; Lub sij hawm tso saib yog ceev ceev, tsis tshua pom tsis muaj tshwm sim tshwm sim; cov yam ntxwv tsis tshua muaj qhov kub zoo, thiab cov zaub tseem pom tau tias pom tshwm sim nyob rau ntawm 40 degrees; cov txheej txheem tsim tau yooj yim, tus nqi tsawg tsawg, qhov luminosity siab, thiab nws yuav tsum tau qhia rau ntawm substrates cov khoom sib txawv.
