Cov xim sawv cev muaj peev xwm ntawm TFT LCD zaub ncaj qha txiav txim siab qhov zoo ntawm qhov pom kev. Los ntawm kev npaj ntawm cov kua siv lead ua kua molecules mus rau qhov tsim ntawm lub backlight system, txhua yam khoom cuam tshuam rau qhov kawg xim tso zis. Los ntawm kev tswj cov kev xa tawm ntawm liab, ntsuab, thiab xiav sub-pixels hauv txhua pixel, hom zaub no tuaj yeem ua tiav txog 16.7 lab xim, npog cov qauv sRGB xim gamut ntau yam.
Raws li cov ntsiab lus tseem ceeb rau kev tsim xim, txoj hauv kev ua haujlwm ntawm cov kua siv lead ua kua ncaj qha cuam tshuam rau cov xim raug. Thaum qhov hluav taws xob tau siv rau nyias - zaj duab xis transistor, cov kua siv lead ua kua molecules deflect, yog li hloov cov nyiaj rov qab uas dhau los ntawm cov kua siv lead ua kua. Qhov no electro-optical effect tso cai rau txhua qhov sub-pixel kom ua tiav 256 qib ntawm greyscale variation. Los ntawm superposition thiab sib tov ntawm peb lub ntsiab xim, nplua nuj xim qhia tau tiav.
Kev nce qib hauv cov teeb pom kev zoo tau txhim kho cov xim ua haujlwm zoo ntawm TFT LCDs. LED backlight thev naus laus zis tuaj yeem tsim lub teeb dawb dawb los ntawm kev ua kom zoo dua phosphor formulations, nteg lub hauv paus ruaj khov rau cov xim kom raug. Kev taw qhia ntawm quantum dot thev naus laus zis tau nthuav dav ntxiv rau cov xim gamut ntau yam. Los ntawm kev sib koom ua ke nanoscale semiconductor hais rau hauv lub teeb pom kev zoo, siab - purity liab thiab ntsuab lub teeb tuaj yeem ua tau zoo siab, ua rau cov zaub xim gamut npog tau yooj yim tshaj NTSC 100% tus qauv.
Kev ua tau zoo ntawm cov tsav tsheb ICs kuj tseem cuam tshuam nrog cov xim raug. TFT LCD zaub feem ntau siv 8-ntsis lossis 10-ntsis tsav tsheb chips, ua ke nrog FRC (Frame Rate Control) thev naus laus zis, kom ua tiav cov khoom muaj peev xwm ntawm 1.07 billion xim. High-precision Gamma kho circuits kom du thiab ntuj greyscale hloov, tiv thaiv xim banding.
Qhov tseeb xim feem ntau yog sawv cev los ntawm ΔE tus nqi- tus nqi me dua, qhov qis dua qhov sib txawv xim. Ib qho kev ntsuas ntsuas tau zoo tuaj yeem ua tiav ΔE < 1. Thaum lub sijhawm ua haujlwm ntawm lub Hoobkas, lub spectrophotometer yog siv los ntsuas cov khoom tso tawm ntawm ntau pua xim thaj ua rau thaj, thiab ICC profile yog tsim los kho cov xim sib txawv. Rau cov xwm txheej ua haujlwm uas cuam tshuam nrog ntau- npo kev sib koom tes, ΔE qhov sib npaug yog qhov tseem ceeb, vim nws tuaj yeem ua kom cov xim sib txawv ntawm ntau yam khoom siv qis dua qhov pom tau.
Kev cuam tshuam ntawm kev saib lub kaum sab xis ntawm kev ua haujlwm xim tsis tuaj yeem raug saib xyuas. IPS thev naus laus zis optimizes cov txheej txheem ntawm cov kua siv lead ua kom nthuav dav saib lub kaum sab xis rau 178 degrees, ua kom cov xim sib xws los ntawm yuav luag txhua qhov kev taw qhia. VA panels muab qhov sib txawv ntau dua thaum tuav lub kaum sab xis pom dav, ua rau muaj kev nthuav dav ntau dua.
Lub teeb nyob ib puag ncig tuaj yeem cuam tshuam loj npaum li cas tib neeg lub qhov muag pom ntawm - xim xim. TFT LCDs feem ntau yog nruab nrog ambient lub teeb sensors uas tau kho lub vijtsam xim kub raws li qhov ci ntsa iab. Nyob rau hauv cov nqe lus ntawm kev tswj xim, kho vajtse calibration tau maj mam dhau los ua tus qauv feature hauv kev qhia. Cov neeg siv tuaj yeem sau ncaj qha cov ntaub ntawv calibration rau hauv cov zaub ua cov nti kom paub meej ntev -lub sij hawm ruaj khov ntawm cov xim xim.
Los ntawm cov neeg siv khoom siv hluav taws xob mus rau cov ntawv thov kev tshaj lij, TFT LCD cov lus qhia txuas ntxiv ua kom pom qhov muaj zog ntawm cov xim sawv cev, ua tsaug rau lawv cov thev naus laus zis paub tab thiab kev hloov pauv tsis tu ncua. Txawm hais tias rau cov neeg tsim qauv nrhiav qhov tseeb- rau- kev tsim tawm lub neej lossis cov neeg siv niaj hnub uas nyiam cov duab zoo nkauj, TFT LCD cov khoom muaj cov xim xim kom tau raws li cov kev xav tau sib txawv.
