(3) Kev txhim kho keeb kwm ntawm LED npo zaub tshuab
Saib rov qab los ntawm kev txhim kho keeb kwm ntawm LEDs, txoj kev loj hlob ntawm cov tsoos LEDs muaj ib tug me ntsis feature, uas yog, feem ntau hom nyob rau hauv lub lag luam yog maj hloov los ntawm sab nraum zoov LED zaub thiab loj-pitch LEDs rau me me-pitch khoom.
Tom qab ntawd nws nkag mus rau cov kev lag luam me me thiab zoo hauv qab P2.5 suab, thiab maj mam nce cov ntawv thov dav hauv sab hauv tsev. Lub teeb hlaws lub suab txuas ntxiv zuj zus, thiab cov txiaj ntsig cov duab txuas ntxiv txhim kho.
Me-pitch LED thev naus laus zis tau tsim sai heev txij li xyoo 2016, thiab tau dhau los ua lub zog tseem ceeb ntawm LED zaub loj hlob nyob rau theem no. Tam sim no, LED me-pitch zaub technology, txheej txheem thiab kev lag luam saw txhawb cov chaw yog cov paub tab.
Tus nqi pheej yig mus txuas ntxiv, thiab qhov chaw loj heev rau cov khoom siv sab hauv tsev tau ua tiav tiav. Txawm li cas los xij, tseem muaj kev txwv kev siv lub cev rau me me-pitch LEDs. Yog li ntawd, me me-pitch Mini / MicroLEDs tau pib los rau hauv lub qhov muag ntawm cov pej xeem.
(4) Kev txhim kho keeb kwm ntawm LCD zaub backlight
Tsoos LED ncaj-lit backlight: Nws yog tam sim no lub ntsiab backlight daws rau cov kua siv lead ua kua. Tus nqi ntawm cov tshuaj no yog tsawg, thiab dynamic partitioning tuaj yeem ua tiav; nws yog thicker thiab ntau dua nyob rau hauv lub zog noj. Kev lig kev cai LED ntug-lit backlight: Nws tuaj yeem ua nyias thiab tsis muaj qhov sib faib ua ke.
Quantum dot backlight: Lub dav xim gamut tuaj yeem ua tiav, tab sis tus nqi tsim khoom kuj yog siab, nws muaj tshuaj lom me ntsis, thiab tus nqi kuj siab. Tsuas yog ob peb lub tuam txhab muaj peev xwm ntau lawm.
Mini LED backlight: Siv cov teeb pom kev ncaj qha, cov tsoos LED tuag loj yog txo mus rau ntawm 100 ~ 200 μm, uas ua rau muaj ntau qhov chaw teeb pom kev zoo. Nrog rau kev tswj dimming hauv cheeb tsam, nws tuaj yeem ua tiav qhov kev hloov pauv hauv cheeb tsam thiab coj qhov pom kev zoo dua.
Cov tshuaj no muaj cov yam ntxwv ntawm lub zog txuag, lub teeb thiab nyias, dav xim gamut, ultra-siab sib piv, zoo dynamic muab faib, thiab lwm yam., uas muaj peev xwm kov yeej cov shortcomings ntawm lwm yam backlight txoj kev, tab sis tam sim no tus nqi ntau lawm kuj siab, thiab nws. yog tsuas yog siv rau high-end zaub.
(5) Micro LED technology xav tau kev tawg
Tam sim no, muaj peb lub ntsiab lus tseem ceeb txwv tsis pub Micro LED: ib qho yog kev hloov pauv loj, uas yog, yuav ua li cas hloov Micro LED chips rau TFT Circuit Court substrates hauv batch.
Thiab raws li lub micron-theem lub voj voog sib dhos los ua ib qho kev sib koom ua ke ntawm ob-dimensional array qauv, qhov thib ob yog qhov teeb meem ntawm lub teeb pixel ntawm peb-xim Micro LED; qhov thib peb yog qhov ntim ntawm Micro LED.
Vim yog qhov tsawg micronization ntawm pixel sib dhos loj ntawm peb lub ntsiab xim Micro LED, nws yog ib qho nyuaj rau ua tiav ultra-high-density ntim. Yuav ua li cas miniaturize LEDs yuav tsum muaj wafer-theem txheej txheem.
Piv txwv li, 4K qib Micro LED npo xav tau ntau dua 8 lab LEDs kom muaj kev sib koom ua ke, yog li theoretically nws yog qhov nyuaj heev los siv nws rau lub vijtsam loj.
Tam sim no, kev lag luam feem ntau ntseeg tias kev hloov pauv loj yog qhov teeb meem loj tshaj plaws uas ntsib Micro LED cov txheej txheem tsim khoom. Yuav ua li cas koom ua ke cov txiaj ntsig thiab kev ua tau zoo thiab hloov ntau txhiab tus LED chips rau TFT substrates yog qhov teeb meem loj tshaj plaws ntsib Micro LED ntau lawm.
Kev hloov pauv loj ntawm Micro LED feem ntau suav nrog ob txoj hauv kev: hloov lub cev thiab hloov tshuaj lom neeg. Ntawm lawv, txoj kev hloov lub cev feem ntau suav nrog cov tshuab electrostatic adsorption hloov chaw sawv cev los ntawm LuxVue (tau los ntawm Apple hauv 2014);
Txoj kev hloov tshuaj lom neeg feem ntau suav nrog micro-transfer printing technology (μTP thev naus laus zis) sawv cev los ntawm X-Celeprint.
(6) Mini LED thev naus laus zis yuav tsum tau tawg
Mini LED ntau lawm tshuab tseem muaj teeb meem, thiab yuav tsum tau siv zog ceev kom ceev industrialization. Txawm hais tias Mini LED zaub tau ua tiav cov khoom xa tuaj me me, tseem muaj ob peb lub fwj hauv cov khoom loj loj uas yuav tsum tau daws ntxiv.
Thawj yog chip manufacturing. Kev tsim khoom loj ntawm Mini LED chips yuav tsum muaj qhov tseeb ntawm sub-micron, thiab cov txheej txheem kuaj tam sim no tsuas yog 10 microns;
Qhov thib ob yog qhov teeb meem ntawm kev hloov loj heev. Kev tsim khoom loj yuav tsum tau hloov pauv cov pixel tuag tsawg dua ib feem ntawm ib lab, tab sis tam sim no nws tsuas yog nce mus txog ib feem ntawm 100,000, thiab cov nqi kho mob kuj tseem siab;
Qhov thib peb yog qhov teeb meem ntawm kev sib txuas ntawm electrode. Tus nqi ntawm electrode kev twb kev txuas flip-chip tshuab yog siab dhau lawm. Tam sim no, tsuas yog cov txheej txheem mounting raug siv nyob rau hauv Suav teb, uas txo cov khoom ntseeg tau;
Qhov thib plaub yog qhov teeb meem tsav tsheb, nws yog ib qho tseem ceeb los tsim kom zoo dua PCB backplane manufacturing thiab TFT backplane tsav tshuab; qhov thib tsib yog qhov teeb meem splicing, cov txheej txheem splicing uas twb muaj lawm tsuas tuaj yeem ua tiav qhov ntev-ntev qhov muag seamlessness, thiab tus du seamless splicing yog qhov nyuaj dua.
