Koj paub tias CRT ua haujlwm yog lub zog ntawm cov teeb taws cua sov, lub cathode yog stimulated, emission ntawm hluav ncaig, hluav taws xob ntim ntawm sab hauv txheej nrog high voltage acceleration, los ntawm lub lens tsom rau ib tus nplua nuj electron nqaj, ntaus ntawm qhov kev tshuaj ntsuam, yog li ntawd phosphor light-emitting. Thiab lub ntsiab cai ntawm CRT yog qhov txawv txav, LCD xav tau los ntawm qab lub teeb ci, thaum lub nqaj ntawm qhov txheej txheem ntawm kua siv ua kua, LCD sab los sis tsis sib haum, zoo li lub LCD zoo li lub qhov rooj, xaiv lub teeb nkag mus los yog tsis tau, peb tuaj yeem pom qhov ntxoov ntxoo ntawm qhov screen, patchwork image.
Tam sim no mainstream kua Crystal zaub yog nyias zaj duab xis transistor LCD (TFTLCD), yog los ntawm cov thawj kua siv lead ua tshuab technology nthuav dav. Tft LCD Rau txhua lub pixel muaj ib qho kev hloov ntawm semiconductor, thiaj li ua tiav ib qho kev tswj hwm ntawm ib lub pixel, cov khoom siv lead ua kua muaj qhwv ntawm TFT iav txheej thiab xim xim txheej, los ntawm kev hloov qhov voltage ntawm lub LCD kom tswj tau qhov kawg ntawm lub teeb khov thiab xim.
Feem ntau, cov kua siv lead ua kua yog pob tshab tshwj tsis yog qhov siv hluav taws xob. Thaum cov pa, ib feem ntawm nws hloov thiab ua opaque. Qhov kev hloov dua tshiab ntawm cov kua qaub no feem ntau yog qeeb (cov lus piav qhia tom qab). Nyob rau xyoo 1992, EMI tshaj tawm tias tsim muaj cov tshiab kua tshuaj siv tshuab ua kua hluav taws xob ua hluav taws xob FroD (FERROELECTRICLCDS). Qhov kom zoo ntawm cov kua siv ua kua siv ferroelectric yog tias qhov lus teb ceev ceev thiab tuaj yeem ncav cuag microsecond. Thiab tsis tas hloov qhov hluav taws xob kuj muaj peev xwm tswj tau tam sim no lub xeev, uas yog, ntau lub zog, uas rau cov laptops, PDAs thiab lwm yam khoom siv txav ceev heev. FLCD muaj ntau yam zoo, tab sis tam sim no muaj qee cov khoom hauv lub lag luam, vim tias FLCD yog qhov kev kho siab heev, nws yooj yim rau kev siv lead ua, tiam sis yuav muaj kev txhim kho yav tom ntej.
Txawm hais tias lub neej yav tom ntej ntawm cov kua siv ua kua Crystalline FLCD tseem tsis paub, tab sis nws kuj muaj qhov sib txawv ntawm qhov loj thiab loj qhov muag pom ntawm qhov kev ua tau zoo ntawm kev ua lag luam ntawm TFT yuav ua rau muaj kev cuam tshuam.
Thaum ua haujlwm kub, lub sijhawm tshuaj tiv thaiv ntawm FLCD tsuas yog 70us! xws li ib lub sij hawm luv luv yuav luag tsis nco qab.
