Lub neej ntev ntawm OLED yog dab tsi?

Thaum cov ntxaij vab tshaus OLED (Organic Light-Emitting Diode) tau dhau los ua qhov chaw nyob hauv cov xov tooj ntse, TVs, thiab cov khoom siv hluav taws xob siab, cov neeg siv khoom thiab cov chaw tsim khoom ib yam tab tom nug cov lus nug txog lawv lub neej ntev. Cov ntxaij vab tshaus ci ntsa iab thiab txuag hluav taws xob no kav ntev npaum li cas tiag tiag - thiab cov yam twg txiav txim siab lawv lub neej ntev?

Kev Tshawb Fawb Tom Qab OLED Degradation

Cov thev naus laus zis OLED siv cov organic compounds uas tso tawm lub teeb thaum hluav taws xob hla dhau lawv. Tsis zoo li cov LCDs ib txwm muaj, uas siv lub teeb nraub qaum, txhua lub pixel hauv OLED zaub ci ntsa iab ntawm nws tus kheej. Qhov no tso cai rau cov xim dub tob dua thiab qhov sib piv zoo dua tab sis ua rau muaj qhov tsis zoo: cov khoom siv organic lwj zuj zus raws sijhawm.

Feem ntau cov chaw tsim khoom ntsuas lub neej ntawm OLED los ntawm kev siv ib nrab ntawm lub neej - lub sijhawm uas lub vijtsam siv los poob 50% ntawm nws qhov ci ntsa iab thawj. Feem ntau cov vaj huam sib luag OLED niaj hnub no, xws li cov hauv cov xov tooj ntse thiab TV zoo, tau ntsuas rau 30,000 txog 100,000 teev ntawm kev siv ua ntej mus txog ib nrab ntawm lub neej. Piv txwv li:

Cov Xov Tooj Ntawm Tes: Yog siv 5-6 teev hauv ib hnub, lub vijtsam OLED yuav kav ntev li 10-15 xyoo ua ntej yuav tsaus ntuj.

Cov TV: Yog siv 8 teev hauv ib hnub, lub TV OLED yuav ua haujlwm tau zoo tshaj plaws rau 8-14 xyoos.

Txawm li cas los xij, lub neej ntev hauv ntiaj teb tiag tiag nyob ntawm ntau yam kev siv, qhov chaw, thiab cov yam ntxwv ib puag ncig.

Cov Yam Tseem Ceeb Uas Cuam Tshuam Rau Lub Neej OLED:

1. Qhov Ci Ntawm Qhov Screen: Qhov ci ntau dua ua rau cov pixel puas sai dua. Kev siv ntev ntawm qhov ci siab tshaj plaws, tshwj xeeb tshaj yog nrog cov khoom tsis txav (piv txwv li, cov logos lossis cov navigation bars), tuaj yeem ua rau hlawv lossis laus tsis sib xws.

2. Kev Siv Xim: Cov subpixels xiav lwj sai dua li cov liab lossis ntsuab, uas ua rau xim hloov pauv raws sijhawm.

3. Kub thiab Av noo: Kub lossis av noo ntau dhau tuaj yeem ua rau cov khoom siv organic tawg sai dua.

Kev Tsim Kho Tshiab Hauv Kev Lag Luam Los Ntev Lub Neej

Cov chaw tsim khoom tau siv cov kev tiv thaiv los daws cov teeb meem no. Samsung's QD-OLED, LG's WRGB OLED, thiab Apple's LTPO cov zaub suav nrog cov thev naus laus zis xws li:

- Pixel Shifting: Cov khoom txav mus los zoo kom tiv thaiv kev hlawv.

- Cov Tshuab Ua Kub: Txo kev ntxhov siab thermal ntawm cov khoom siv organic.

- Cov Algorithms Siab Tshaj Plaws: Kho qhov kaj thiab xim sib npaug.

 Raws li DSCC (Display Supply Chain Consultants), cov vaj huam sib luag OLED tshiab uas tau tso tawm hauv xyoo 2023 qhia txog kev txhim kho 15-20% hauv lub neej piv rau cov qauv xyoo 2020.

Cov kws tshaj lij pom zoo yuav ua li cas kom OLED ruaj khov

- Siv cov chaw teeb tsa qhov kaj tsis siv neeg thiab zam kom qhov kaj ntev tshaj plaws.

- Qhib cov screen savers lossis hom pw tsaug zog rau cov ntsiab lus static.

- Hloov kho firmware kom tau txais txiaj ntsig los ntawm kev ua kom zoo dua ntawm cov chaw tsim khoom.

Yav tom ntej ntawm OLED lub neej ntev

Txawm hais tias kev txhawj xeeb tseem muaj, cov qauv kev lag luam qhia txog kev ntseeg siab. LG Display nyuam qhuav tshaj tawm lub vaj huam sib luag OLED tshiab uas ntsuas tau 150,000 teev (17 xyoo ntawm kev siv 24/7), tsom mus rau cov paib lag luam. Lub caij no, UBI Research kwv yees tias los ntawm xyoo 2027, cov subpixels xiav OLED - qhov txuas tsis muaj zog tshaj plaws - yuav pom lub neej ntev ob npaug vim yog cov khoom siv phosphorescent.

Raws li Dr. Jessica Smith, tus kws tshaj lij ntawm MIT, tau hais tias: "OLED tsis zoo tag nrho, tab sis nws lub neej tam sim no dhau lub voj voog hloov kho tshiab rau feem ntau ntawm cov khoom siv. Rau tus neeg siv nruab nrab, kev tsim kho tshiab ntawm lub vijtsam yuav dhau qhov kev puas tsuaj."

Nrog rau kev siv OLED nthuav dav mus rau hauv cov laptops, cov zaub tsheb, thiab cov khoom siv uas muaj peev xwm quav tau, kev nkag siab txog nws cov kev txwv - thiab kev hloov pauv ntawm cov kev daws teeb meem - tseem ceeb rau cov neeg siv khoom uas tab tom nrhiav kev lag luam zaub zoo tshaj plaws.
