Qhov txawv ntawm OLED thiab QLED

Nyob rau niaj hnub no lub ntsiab high-end zaub technologies, OLED (Organic Light-Emitting Diode) thiab QLED (Quantum Dot Light-Emitting Diode) yog undoubtedly ob lub ntsiab lus tseem ceeb. Txawm hais tias lawv cov npe zoo sib xws, lawv sib txawv hauv cov qauv kev ua haujlwm, kev ua tau zoo, thiab cov txheej txheem tsim khoom, yuav luag sawv cev rau ob txoj kev txhim kho sib txawv rau kev siv thev naus laus zis.

Hauv paus, OLED zaub thev naus laus zis yog ua raws li lub hauv paus ntsiab lus ntawm cov organic electroluminescence, thaum QLED tso siab rau lub electroluminescent lossis photoluminescent mechanism ntawm inorganic quantum dots. Txij li cov ntaub ntawv inorganic feem ntau muaj ntau dua thermal thiab tshuaj lom neeg ruaj khov, QLED theoretically muaj qhov zoo ntawm lub teeb qhov chaw ruaj khov thiab lifespan. Qhov no kuj yog vim li cas ntau tus xav txog QLED txoj kev cog lus rau cov khoom siv thev naus laus zis tom ntej.

Cias muab, OLED emits lub teeb los ntawm cov khoom siv organic, thaum QLED emits lub teeb los ntawm inorganic quantum dots. Yog tias LED (Light-Emitting Diode) piv rau "niam", ces Q thiab O sawv cev rau ob txoj kev siv thev naus laus zis. LED nws tus kheej, raws li ib tug semiconductor lub teeb-emitting ntaus ntawv, excites lub teeb lub zog thaum tam sim no dhau los ntawm cov khoom siv luminescent, ua tiav photoelectric hloov dua siab tshiab.

Txawm hais tias ob qho tib si OLED thiab QLED yog raws li lub hauv paus ntsiab lus ntawm lub teeb-emitting txoj cai ntawm LED, lawv nyob deb tshaj li ib txwm LED qhia nyob rau hauv cov nqe lus ntawm luminous efficiency, pixel ceev, xim kev ua tau zoo, thiab lub zog noj. Ordinary LED zaub cia siab rau electroluminescent semiconductor chips, nrog rau cov txheej txheem tsim khoom yooj yim. Txawm hais tias high-density me-pitch LED qhia tau tam sim no tsuas yog ua tiav qhov tsawg kawg nkaus pixel suab ntawm 0.7 hli. Hauv qhov sib piv, ob qho tib si OLED thiab QLED xav tau kev tshawb fawb kev tshawb fawb siab heev thiab cov qauv ntawm cov khoom siv rau kev tsim khoom. Tam sim no, tsuas yog ob peb lub teb chaws xws li lub teb chaws Yelemees, Nyiv, thiab Kaus Lim Qab Teb muaj peev xwm koom nrog lawv cov khoom siv hluav taws xob sab saud, ua rau muaj kev cuam tshuam kev siv tshuab siab heev.

Cov txheej txheem tsim khoom yog lwm qhov sib txawv loj. Lub teeb-emitting qhov chaw ntawm OLED yog cov organic molecules, uas tam sim no tsuas yog siv cov txheej txheem evaporation-ua cov ntaub ntawv organic rau hauv cov qauv me me nyob rau hauv qhov kub thiab txias thiab tom qab ntawd hloov pauv lawv mus rau qhov chaw teev tseg. Txoj kev no xav tau ib puag ncig siab heev, suav nrog cov txheej txheem nyuaj thiab cov khoom siv meej, thiab qhov tseem ceeb tshaj plaws, ntsib cov teeb meem tseem ceeb hauv kev ua kom tau raws li cov kev xav tau ntawm cov ntxaij vab tshaus loj.

Ntawm qhov tod tes, lub teeb-emitting chaw ntawm QLED yog semiconductor nanocrystals, uas tuaj yeem yaj hauv ntau yam kev daws teeb meem. Qhov no tso cai rau kev npaj los ntawm kev daws teeb meem, xws li tshuab luam ntawv. Ntawm ib sab, qhov no tuaj yeem txo cov nqi tsim khoom, thiab ntawm qhov tod tes, nws tawg los ntawm cov kev txwv ntawm qhov screen loj, nthuav daim ntawv thov scenarios.

Hauv cov ntsiab lus, OLED thiab QLED sawv cev rau qhov kawg ntawm cov organic thiab inorganic teeb-emitting technologies, txhua tus muaj nws tus kheej lub zog thiab tsis muaj zog. OLED paub txog nws qhov sib piv tsis tshua muaj siab thiab hloov pauv cov yam ntxwv, thaum QLED tau txais txiaj ntsig rau nws cov khoom siv ruaj khov thiab tus nqi peev. Cov neeg siv khoom yuav tsum xaiv raws li lawv cov kev xav tau tiag tiag.
