Lub neej expectancy ntawm OLED yog dab tsi?

Raws li OLED (Organic Light-Emitting Diode) cov ntxaij vab tshaus dhau los ua thoob plaws hauv lub xov tooj ntawm tes, TVs, thiab cov khoom siv hluav taws xob siab, cov neeg siv khoom thiab cov neeg tsim khoom sib xws tau nug txog lawv lub neej ntev. Ntev npaum li cas cov vibrant, lub zog-npaum cov lus qhia tau kawg - thiab dab tsi cuam tshuam txiav txim siab lawv lub neej?

Kev Tshawb Fawb Tom Qab OLED Degradation

OLED thev naus laus zis tso siab rau cov organic tebchaw uas tawm lub teeb thaum muaj hluav taws xob dhau los ntawm lawv. Tsis zoo li cov LCDs ib txwm siv, uas siv lub teeb rov qab, txhua pixel hauv OLED zaub illuminates nws tus kheej. Qhov no tso cai rau kev sib sib zog nqus dub thiab qhov sib txawv zoo dua tab sis qhia txog qhov tsis muaj peev xwm tseem ceeb: cov ntaub ntawv organic degrade dhau sijhawm.

Cov neeg tsim khoom feem ntau ntsuas OLED lifespan nyob rau hauv cov nqe lus ntawm ib nrab-lub neej-lub sij hawm nws yuav siv sij hawm rau ib tug screen kom poob 50% ntawm nws thawj brightness. Feem ntau niaj hnub OLED vaj huam sib luag, xws li cov hauv xov tooj smartphones thiab TVs, raug ntsuas rau 30,000 txog 100,000 teev ntawm kev siv ua ntej mus txog ib nrab-lub neej. Piv txwv li:

Smartphones: Thaum 5-6 teev ntawm kev siv txhua hnub, ib qho screen OLED tuaj yeem kav ntev li 10-15 xyoo ua ntej pom qhov dimming.

TVs: Nrog 8 teev ntawm kev siv txhua hnub, OLED TV yuav tswj tau qhov ua tau zoo tshaj plaws rau 8-14 xyoo.

Txawm li cas los xij, lub neej ntev tiag tiag nyob ntawm qhov kev siv cov qauv, kev teeb tsa, thiab ib puag ncig yam.

Yam tseem ceeb cuam tshuam rau OLED Lifespan:

1. Screen Brightness: Siab dua brightness accelerates pixel hnav. Kev siv ntev ntev ntawm qhov ci ntsa iab, tshwj xeeb tshaj yog nrog cov ntsiab lus zoo li qub (xws li, logos lossis navigation bars), tuaj yeem ua rau hlawv-hauv lossis tsis sib xws.

2.Color Siv: Xiav subpixels degrade sai dua li cov liab lossis ntsuab, uas yuav ua rau xim hloov lub sijhawm.

3. Thaum tshav kub kub thiab av noo: Cov cua kub ntau dhau los yog noo noo tuaj yeem ua rau cov khoom tawg yooj yim.

Kev lag luam Innovation rau Extend Lifespan

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

- Pixel Shifting: Subtly txav cov khoom zoo li qub los tiv thaiv kev kub hnyiab.

- Thaum tshav kub kub Dissipation Systems: Txo thermal stress ntawm cov ntaub ntawv organic.

- Advanced Algorithms: Hloov kho qhov ci thiab xim sib npaug.

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

Cov kws tshaj lij pom zoo yuav ua li cas txhawm rau txhim kho OLED ntev

- Siv qhov teeb tsa teeb pom kev zoo pib thiab zam qhov ci ci ntev ntev.

- Ua kom lub vijtsam txuag lossis hom pw tsaug zog rau cov ntsiab lus zoo li qub.

- Hloov kho firmware kom tau txais txiaj ntsig los ntawm kev tsim kho kom zoo.

Lub neej yav tom ntej ntawm OLED Ntev

Txawm hais tias muaj kev txhawj xeeb tsis tu ncua, kev lag luam kev lag luam qhia kev ntseeg siab. LG Display tsis ntev los no tau tshaj tawm OLED vaj huam sib luag tshiab rau 150,000 teev (17 xyoo ntawm 24/7 siv), tsom rau kev lag luam kos npe. Lub caij no, UBI Kev Tshawb Fawb kwv yees tias los ntawm 2027, xiav OLED subpixels - qhov txuas tsis muaj zog tshaj plaws - yuav pom kev ua neej nyob ob npaug vim yog cov khoom siv phosphorescent tawg.

Raws li Dr. Jessica Smith, tus kws tshaj lij thev naus laus zis ntawm MIT, sau tseg: "OLED tsis zoo tag nrho, tab sis nws lub neej tam sim no dhau ntawm lub voj voog hloov tshiab rau feem ntau cov khoom siv.

Nrog OLED kev saws me nyuam nthuav dav mus rau hauv lub laptops, cov khoom siv tsheb, thiab cov foldables, nkag siab txog nws cov kev txwv - thiab cov kev daws teeb meem hloov zuj zus - tseem yog qhov tseem ceeb rau cov neeg siv khoom siv kev lag luam zoo tshaj plaws.
