1. Polymer kua Crystal
Cov kua ua kua yog cov khoom nyob rau hauv lub xeev tshwj xeeb, feem ntau tsis yog cov khoom ua kua, tab sis nyob rau hauv ib lub xeev nyob nruab nrab. Lawv qhov kev npaj molecular yog me ntsis kev coj ua, tab sis tsis ruaj khov li cov khib nyiab thiab tuaj yeem ntws zoo li kua. Cov cuab yeej tshwj xeeb no ua rau cov kua siv lead ua kua ua lub luag haujlwm tseem ceeb hauv kev siv thev naus laus zis. Cov kua siv lead ua kua molecules yog tsim los ntawm cov pas nrig ntev lossis cov qauv zoo li disk, thiab lawv tuaj yeem hloov kho lawv txoj kev npaj raws li kev hloov pauv ntawm cov xwm txheej sab nraud xws li hluav taws xob, teb sib nqus, kub, thiab siab. Qhov kev hloov pauv no ncaj qha cuam tshuam rau cov khoom siv kho qhov muag ntawm cov kua siv lead ua kua, xws li lub teeb kis tau tus mob, thiab yog li dhau los ua lub hauv paus ntawm kev siv thev naus laus zis.
2. LCD Main Hom
covTN LCD(Twisted Nematic, TN)： Hom LCD no feem ntau yog siv rau cov cwj mem lossis cov cim qhia thiab muaj tus nqi qis dua. TN LCD muaj lub kaum sab xis saib nqaim tab sis teb, ua rau nws haum rau cov ntawv thov uas yuav tsum tau hloov kho sai.
covSTN LCD(Super Twisted Nematic, STN)： STN LCD muaj lub kaum sab xis pom dav dua TN LCD thiab tuaj yeem txhawb nqa dot matrix thiab cov cim ua cim. Thaum STN LCD ua ke nrog transflective lossis reflective polarizer, nws tuaj yeem tso tawm ncaj qha yam tsis muaj lub teeb rov qab, yog li txo qis kev siv hluav taws xob. Tsis tas li ntawd, STN LCDs tuaj yeem kos nrog cov haujlwm yooj yim kov, ua rau lawv muaj kev xaiv zoo tshaj plaws rau lub cev pob khawm.
VA LCD(Vertical Alignment, VA):VA LCD nta qhov sib txawv siab thiab pom dav dav, ua rau nws haum rau cov xwm txheej uas xav tau qhov sib txawv siab thiab pom tseeb. VA LCDs feem ntau yog siv nyob rau hauv high-end zaub los muab cov xim nplua nuj thiab cov duab ntse dua.
TFT LCD(Thin Film Transistor, TFT): TFT LCD yog ib qho ntawm ntau hom LCDs, nrog kev daws teeb meem siab dua thiab kev ua haujlwm zoo dua xim. TFT LCD yog dav siv nyob rau hauv high-end zaub, muab cov duab kom meej thiab ceev teb lub sij hawm.
OLED(Organic Light-Emitting DiodeOLED): Txawm hais tias OLED tsis yog LCD thev naus laus zis, nws tau hais ntau zaus hauv kev sib piv rau LCD. OLEDs yog tus kheej teeb pom kev zoo, muab cov xim nplua nuj thiab kev ua haujlwm dub tob, tab sis ntawm tus nqi siab dua.
3. Daim ntawv thov
Cov ntawv thov LCD yog dav, suav nrog tab sis tsis txwv rau:
Cov cuab yeej tswj kev lag luam: xws li cov khoom siv tswj kev lag luam.
Nyiaj txiag terminals: xws li POS tshuab.
Cov khoom siv sib txuas lus: xws li xov tooj.
Cov khoom siv hluav taws xob tshiab: xws li cov khoom siv hluav taws xob.
Hluav taws kub tswb: siv los tso saib cov ntaub ntawv tswb.
3D tshuab luam ntawv: siv los tso saib lub lag luam interface.
Cov cheeb tsam daim ntawv thov no qhia tau hais tias muaj ntau yam thiab dav ntawm LCD thev naus laus zis, qhov twg LCDs ua lub luag haujlwm tseem ceeb los ntawm tus nqi qis qis yuav tsum tau thov rau kev thov kev lag luam thiab kev tshaj lij.
