Qhov txawv ntawm OLED thiab QLED

Hauv cov thev naus laus zis siab tshaj plaws niaj hnub no, OLED (Organic Light-Emitting Diode) thiab QLED (Quantum Dot Light-Emitting Diode) yog ob lub ntsiab lus tseem ceeb. Txawm hais tias lawv lub npe zoo sib xws, lawv txawv ntau hauv cov ntsiab cai kev siv tshuab, kev ua tau zoo, thiab cov txheej txheem tsim khoom, yuav luag sawv cev rau ob txoj hauv kev sib txawv kiag li rau thev naus laus zis tso saib.

Lub hauv paus ntsiab lus, OLED cov thev naus laus zis yog raws li lub hauv paus ntsiab lus ntawm cov organic electroluminescence, thaum QLED vam khom lub electroluminescent lossis photoluminescent mechanism ntawm inorganic quantum dots. Vim tias cov ntaub ntawv inorganic feem ntau muaj kev ruaj khov thermal thiab tshuaj lom neeg siab dua, QLED theoretically muaj qhov zoo dua hauv kev ruaj khov ntawm lub teeb thiab lub neej ntev. Qhov no kuj yog vim li cas ntau tus neeg xav tias QLED yog qhov kev coj ua zoo rau cov thev naus laus zis tom ntej.

Hais yooj yim xwb, OLED tso tawm lub teeb los ntawm cov khoom siv organic, thaum QLED tso tawm lub teeb los ntawm cov inorganic quantum dots. Yog tias LED (Light-Emitting Diode) piv rau "niam," ces Q thiab O sawv cev rau ob txoj kev siv tshuab "txiv" sib txawv. LED nws tus kheej, ua lub cuab yeej semiconductor teeb-emitting, ua rau lub zog teeb pom kev zoo thaum tam sim no hla dhau cov khoom siv luminescent, ua tiav kev hloov pauv photoelectric.

Txawm hais tias OLED thiab QLED ob leeg yog raws li lub hauv paus ntsiab lus ntawm LED, lawv dhau qhov kev pom LED ib txwm muaj hauv kev ua haujlwm zoo, pixel density, kev ua haujlwm xim, thiab kev tswj kev siv hluav taws xob. Cov zaub LED ib txwm siv cov chips electroluminescent semiconductor, nrog rau cov txheej txheem tsim khoom yooj yim. Txawm tias cov zaub LED me me uas muaj qhov siab tam sim no tsuas yog ua tiav qhov pixel pitch tsawg kawg nkaus ntawm 0.7 hli. Qhov sib piv, ob qho tib si OLED thiab QLED xav tau kev tshawb fawb siab heev thiab cov qauv siab los ntawm cov ntaub ntawv mus rau kev tsim khoom siv. Tam sim no, tsuas yog ob peb lub tebchaws xws li Lub Tebchaws Yelemees, Nyiv Pooj, thiab Kaus Lim Qab Teb muaj peev xwm koom nrog lawv cov saw hlau xa khoom, ua rau muaj kev cuam tshuam siab heev.

Cov txheej txheem tsim khoom yog lwm qhov sib txawv loj. Lub chaw teeb pom kev zoo ntawm OLED yog cov organic molecules, uas tam sim no feem ntau siv cov txheej txheem evaporation - ua cov khoom siv organic rau hauv cov qauv me me hauv qab qhov kub siab thiab tom qab ntawd rov ua kom raug rau ntawm qhov chaw tshwj xeeb. Txoj kev no xav tau cov xwm txheej 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 loj hauv kev ua kom tau raws li cov kev xav tau ntawm cov ntxaij vab tshaus loj.

Ntawm qhov tod tes, lub hauv paus ntawm lub teeb ci ntawm QLED yog cov nanocrystals semiconductor, uas tuaj yeem yaj rau hauv ntau yam kev daws teeb meem. Qhov no tso cai rau kev npaj los ntawm cov txheej txheem raws li kev daws teeb meem, xws li thev naus laus zis luam ntawv. Ntawm ib sab tes, qhov no tuaj yeem txo cov nqi tsim khoom, thiab ntawm qhov tod tes, nws tawg los ntawm cov kev txwv ntawm qhov loj ntawm lub vijtsam, nthuav dav cov xwm txheej ntawm daim ntawv thov.

Hauv kev xaus lus, OLED thiab QLED sawv cev rau qhov siab tshaj plaws ntawm cov thev naus laus zis organic thiab inorganic light-emitting, txhua tus muaj nws tus kheej lub zog thiab qhov tsis muaj zog. OLED paub txog nws qhov sib piv siab heev thiab cov yam ntxwv ntawm kev tso saib yooj ywm, thaum QLED nyiam nws qhov ruaj khov ntawm cov khoom siv thiab tus nqi. Cov neeg siv khoom yuav tsum xaiv raws li lawv cov kev xav tau siv tiag tiag.
