Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm LCD zaub feem ntau suav nrog kev tswj hluav taws xob ntawm cov kua siv lead ua kua molecules thiab kev hloov pauv ntawm lub teeb.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm: LCD zaub siv hluav taws xob los tswj kev teeb tsa ntawm cov kua siv lead ua kua molecules, yog li hloov pauv kev sib kis lossis kev cuam tshuam ntawm lub teeb. Thaum tam sim no dhau los ntawm cov kua siv lead ua kua txheej, cov kev taw qhia ntawm cov kua siv lead ua kua molecules yuav hloov, uas yuav cuam tshuam rau kev nthuav tawm cov kev taw qhia thiab kev siv lub teeb, thiab tom qab ntawd tsim cov duab ntawm qhov screen.
Backlight thiab xim lim: Lub vijtsam LCD nws tus kheej tsis tawm lub teeb, thiab lub teeb pom kev zoo yuav tsum tau muab lub teeb. Tom qab cov teeb no dhau los ntawm cov kua siv lead ua kua, lawv dhau los ntawm cov xim lim los ua cov duab peb pom. Cov ntxaij lim dej feem ntau muaj xim liab, ntsuab, thiab xiav cov ntxaij lim dej, uas tsim cov pixels raws li kev sib xyaw ua ke kom pom cov duab xim.
Polarizer thiab hluav taws xob tswj birefringence: Cov kua siv lead ua kua molecules tuaj yeem hloov lub polarization lub xeev ntawm lub teeb nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb. Los ntawm kev tswj cov cuab yeej no ntawm cov kua siv lead ua kua molecules, kev sib kis lossis kev xav ntawm lub teeb tuaj yeem raug kho kom meej kom ua tiav cov duab pom. Polarizers yog siv los tswj lub polarization kev taw qhia ntawm lub teeb thiab yog siv nrog rau cov kua siv lead ua txheej kom ua tau zoo dua lub teeb hloov.
Scan tsav thiab teeb liab ua: Hauv cov ntxaij vab tshaus LCD, scan tsav ICs yog lub luag haujlwm rau kev tswj xyuas cov pixels thiab ua cov teeb liab. Lawv xyuas kom meej tias txhua pixel tuaj yeem teb tau raws li cov teeb liab pom, yog li ua tiav cov duab zoo siab -cov duab zoo.
