Tsis ntev los no, BOE pawg neeg tshawb fawb tau luam tawm ib daim ntawv hu ua Novel Package Design Enhances Optical Efficiency of Micro LED Displays hauv phau ntawv xov xwm Information Display.
Cov Txheej Txheem Tsim Khoom Siv Micro LED Zaub (Duab los ntawm: Cov Ntaub Ntawv Qhia)
Txoj kev tshawb fawb no tau tawm tswv yim txog txoj kev npaj ntim khoom Micro LED tshiab, uas daws tau cov teeb meem kev lag luam xws li kev tso tawm ntawm cov chips micro LED sab nraud, kev siv hluav taws xob tsawg, thiab kev hloov xim.
Nws tau tshaj tawm tias thaum qhov loj ntawm pixel txo qis dua 50μm, thaj tsam ntawm lub chip sidewall nce ntxiv, ua rau muaj kev cuam tshuam ntxiv rau sab nraud thiab txo qis kev cuam tshuam sab saud ntawm Micro LEDs. Qhov no ua rau poob qhov ci ntsa iab thiab kev hloov pauv xim, txwv tsis pub siv Micro LEDs hauv cov xwm txheej tso saib siab.
Txhawm rau daws qhov teeb meem no, pab pawg tshawb fawb ntawm BOE tau tsim cov qauv ntim khoom sib xyaw ua ke uas muaj cov nplaum pob tshab uas muaj cov ntsuas siab, cov roj dawb uas muaj cov xim ci ntsa iab, cov microlens arrays, thiab cov xim dub matrix (BM).
Los ntawm kev qhia txog cov txheej txheem gradient refractive index ntawm Micro LED chips, cov kws tshawb fawb tau txhim kho lub kaum sab xis ntawm lub teeb tawm ntawm sab saum toj ntawm lub chip, ua rau lub kaum sab xis tseem ceeb ntawm 25 degrees mus rau qhov siab tshaj plaws ntawm 65.9 degrees thiab txhim kho qhov ua tau zoo ntawm kev rho tawm lub teeb sab saum toj.
Lub caij no, cov resin dawb reflective residues tsim cov qauv trapezoidal isosceles ntawm cov chips, uas tuaj yeem sib sau ua ke thiab tawg lub teeb, ua rau lub teeb ci ntsa iab ntawm 0 ° saib lub kaum sab xis li ntawm 27%. Tsis tas li ntawd, cov txheej txheem plasma los tshem tawm cov nplaum seem ua kom lub teeb tsis muaj kev cuam tshuam.
Hais txog kev tswj lub teeb, pab neeg tau siv cov thev naus laus zis nanoimprint lithography los tsim cov microlens arrays uas muaj qhov tseeb siab, ua tiav kev sib sau ua ke ntawm lub teeb hauv ±60°.
Cov txiaj ntsig simulation qhia tau tias thaum lub lens curvature yog 0.03 thiab qhov refractive index yog 1.85, lub teeb ci ntsa iab nce ntxiv ntau dua 53%. Tsis tas li ntawd, txoj kev tshawb fawb tau qhia txog cov qauv dub matrix rau hauv txheej iav ntim khoom, ua kom txo qhov kev cuam tshuam tsawg dua 2% thiab ua tiav qhov sib piv siab tshaj 20,000: 1, txhim kho qhov zoo ntawm cov zaub.

BOE pawg neeg tshawb fawb tau hais tias txoj kev npaj no tsis yog tsuas yog ua tiav cov kev tshawb pom hauv kev ua haujlwm zoo thiab kev sib xws xwb tab sis kuj xav txog kev ntseeg siab ntawm kev ntim khoom. Kev sib xyaw ua ke ntawm lub iav npog thiab OCA (Optical Clear Adhesive) txheej txhim kho cov khoom tiv thaiv dej, tiv thaiv kev oxidation, thiab hnav-resistant, muab txoj hauv kev txhim khu kev qha rau kev siv ntau lawm ntawm Micro LEDs hauv cov teb xws li cov khoom tso saib tsheb, AR / VR headsets, thiab cov khoom siv hnav tau.
BOE tsis yog tsuas yog ua tiav cov txiaj ntsig tshawb fawb Micro LED tshiab xwb tab sis kuj tseem txuas ntxiv txhawb kev txhim kho Mini / Micro LED cov thev naus laus zis tso saib ncaj qha thiab cov ntawv thov.
