Raws li cov ntsiab lus tseem ceeb ntawm cov khoom siv hluav taws xob, cov qauv tsim ntawm kev lag luam TFT LCD zaub ncaj qha cuam tshuam rau kev pom kev ua haujlwm, kev ntseeg tau, thiab cov nqi tsim khoom. Los ntawm cov ntaub ntawv yooj yim mus rau qhov kev ua tau zoo ntawm kev kho qhov muag, txhua theem yuav tsum tau muab xam kom meej thiab tsim kho tshiab. Tsab ntawv xov xwm no yuav tshuaj xyuas nws cov kev tsim kho tseem ceeb thiab cov yam ntxwv tseem ceeb, nthuav qhia cov neeg nyeem nrog kev ua tiav cov txheej txheem ntawm cov khoom siv hluav taws xob zoo nkauj no.
Nyob rau hauv kev tsim ntawm lub backlight module, lub microstructural layout ntawm lub teeb qhia phaj txiav txim lub uniformity ntawm illumination. Cov txheej txheem xws li laser engraving lossis txhaj tshuaj molding yog ua haujlwm los tsim ntau lab micron- nplai prism qauv ntawm cov ntawv acrylic nrog lub thickness ntawm 0.1-0.3 hli. Noj ntug-lit backlighting ua piv txwv, LED lub teeb tuav feem ntau muab tso rau ntawm ob sab ntawm cov zaub, hloov cov teeb pom kev zoo rau hauv qhov chaw teeb pom kev zoo los ntawm kev tsim tshwj xeeb wedge- zoo li lub teeb qhia daim phiaj. Qee cov qauv suav nrog cov tshuab dimming hauv zos, faib lub teeb rov qab mus rau ntau pua thaj chaw tswj nws tus kheej. Ua ke nrog cov duab ua algorithms, qhov no ua tiav qhov sib piv zoo sib xws ntawm txog li ib lab rau ib qho.
Lub nyias - zaj duab xis transistor (TFT) array yog lub hauv paus ntawm kev tsav tsheb, thiab nws cov qauv tsim ncaj qha cuam tshuam rau pixel teb ceev. TFT substrates feem ntau siv qis-kub polysilicon thev naus laus zis, muab cov khoom siv hluav taws xob ntau dua 100 npaug siab dua li ntawm amorphous silicon. Nyob rau hauv Gen 6 cov kab ntau lawm, iav substrates ntsuas txog 1850 mm × 1500 mm, tso cai rau ntau txhiab TFT arrays rau TFT LCD zaub yuav tsum fabricated ib txhij los ntawm photolithography. Cov qauv tsim tseem ceeb suav nrog cov kab dav dav - mus rau - qhov ntev piv, qhov muaj peev xwm khaws cia tus nqi, thiab kev tiv thaiv kab mob parasitic. Gate driver circuit integration technology ncaj qha cov ntaub ntawv scanning tsav circuits ntawm array substrate, txo tus naj npawb ntawm cov khoom sab nraud.
Cell gap tswj yog ib qho tseem ceeb parameter cuam tshuam cov lus teb ceev hauv cov kua siv lead ua kua cell. Siv spherical spacers 3-5 μm nyob rau hauv txoj kab uas hla ua ke nrog photoresist barriers, lub cell thickness yog khaws cia nyob rau hauv 2.5-4.5 μm. Polymer-stabilized alignment (PSA) ntxiv 0.3% cov khoom siv photosensitive rau cov kua siv lead ua kua molecules; tom qab UV curing, ib tug nano-scale anchoring qauv yog tsim, txo lub sij hawm teb rau qis dua 5 ms. Ntug sealants siv epoxy resin doped nrog nyiaj hmoov, muab ob qho tib si airtightness thiab electrostatic shielding. Rau 55-nti 4K vaj huam sib luag, qhov kev faib tawm raug ntawm lub foob yuav tsum tswj tsis pub dhau ± 0.1 hli, nrog cov dej noo permeability tom qab kho kom qis dua 0.01 g / m²·hnub.
Kev sib raug zoo ntawm cov xim lim thiab TFT array ncaj qha cuam tshuam rau aperture piv. Cov kab ntau lawm niaj hnub siv CCD lub zeem muag qhov chaw los tswj qhov kev sib raug zoo ntawm RGB pixels thiab TFTs hauv ± 1.5 μm. Cov ntxaij lim dej tshiab siv cov khoom siv photoresist nrog cov xim purity zoo dua, ua tiav cov chromaticity kev sib koom tes x- tus nqi ntawm 0.68 rau cov lim dej liab thiab ay- tus nqi ntawm 0.71 rau cov lim dej ntsuab.
Cov qauv tsim ntawm kev lag luam TFT LCD zaub yog hloov zuj zus mus rau ultra- bezels nqaim, siab ib puag ncig kam rau ua, thiab ntau- ua haujlwm sib koom ua ke. Tsav los ntawm kev thov los ntawm AR / VR cov khoom siv, pixel ceev tau dhau 1200 PPI. Cov thev naus laus zis no txuas ntxiv nthuav dav daim ntawv thov ciam teb ntawm TFT LCDs, tswj hwm lawv txoj haujlwm tseem ceeb hauv thaj chaw xws li kev tswj hwm kev lag luam thiab cov khoom siv tsheb.
