Tus qauv ntawm TFT LCD
TFT LCD (nyias zaj duab xis transistor kua siv lead ua zaub) yog tsim los ntawm backlight + polarizer + kua siv lead ua txheej + nyias zaj duab xis transistor + xim lim + iav substrate + tsav Circuit Court. Txhua feem ntawm nws muaj lub luag haujlwm tshwj xeeb, thiab los ntawm kev sib koom tes, cov duab zoo tuaj yeem ua tiav. Cov txheej txheem molecular nyob rau hauv cov kua siv lead ua kua txheej yog tswj los ntawm electrodes, thiab cov xim zaub yog tswj los ntawm kev koom tes ntawm cov ntxaij lim dej. Yog li dab tsi yog lub luag haujlwm ntawm txhua qhov khoom?
1. Backlight yog ib qho teeb pom kev zoo
Feem ntau siv yog LED backlight (nrog LED teeb hlaws) thiab lub teeb qhia phaj (LED teeb hlaws dai tsim los ntawm PCB pawg thawj coj saib). Nws txoj haujlwm yog los muab cov teeb pom kev zoo uas yuav tsum tau ua kom pom lub teeb pom kev zoo. Nws tuaj yeem siv rau hauv qhov chaw tshwj xeeb.
2. Polarizer
Pem hauv ntej polarizer: nyob rau pem hauv ntej ntawm cov zaub, nws muaj peev xwm ua kom lub teeb propagate nyob rau hauv ib qho kev taw qhia.
Pem hauv ntej polarizer: nyob tom qab cov kua siv lead ua kua txheej, lub hauv paus ntsiab lus ntawm kev ua haujlwm yog los tswj lub teeb pom kev hauv cov kua siv lead ua kua.
3. Cov kua siv lead ua kua txheej
Cov kua siv lead ua kua molecules: nruab nrab ntawm ob lub iav substrates, kua siv lead ua kua molecules tuaj yeem hloov lawv txoj kev npaj raws li qhov kev txiav txim ntawm hluav taws xob teb.
Interlayer nrug: Feem ntau yog cov khoom siv tshwj xeeb polymer (xws li polyimide) tswj qhov sib nrug.
4. Thin Film Transistor (TFT)
Muaj nuj nqi: Txhua pixel feem ntau yog tswj los ntawm nyias zaj duab xis transistor (TFT). TFT yog lub luag haujlwm kho qhov voltage, yog li cuam tshuam rau kev npaj ntawm cov kua siv lead ua kua molecules, kom txhua pixel qhia cov xim sib txawv thiab ci ntsa iab.
Structure: TFT feem ntau yog ua los ntawm cov khoom siv silicon thiab muab tso rau hauv iav substrate los tsim ib lub voj voog.
5. Xim lim
RGB lim: Muaj peb xim xim ntawm cov xim liab, ntsuab thiab xiav ntawm ob sab ntawm cov kua siv lead ua kua, uas tso cai rau cov xim sib xws ntawm lub teeb kom dhau los ua cov xim xav tau.
Kev Npaj: Cov xim lim ua raws li cov kua siv lead ua kua txheej hauv cov qauv tshwj xeeb (xws li kab pheeb ces kaum) kom ua tiav cov yeeb yam zoo nkauj.
6. iav substrate
Pem hauv ntej substrate: Nyob rau pem hauv ntej ntawm cov kua siv lead ua kua zaub, feem ntau yog pob tshab electrodes (xws li indium tin oxide, ITO) los tsim electrodes.
Tsheb substrate: Nyob tom qab cov kua siv lead ua kua zaub, nrog built-in TFT Circuit Court thiab tsav Circuit Court.
7. Tsav Circuit Court
Muaj nuj nqi: Tswj thiab tsav TFT ua haujlwm, thiab xa cov teeb liab mus rau cov kua siv lead ua kua txheej los tsim cov duab.
Qhov chaw: Feem ntau embedded nyob rau hauv lub rear substrate thiab ua ke nrog TFT.
Txhua yam ntawm tftLCD tuaj yeem tso tawm ntau cov xim thiab cov duab zoo nkauj los ntawm kev sib koom tes, ua rau cov ntaub ntawv pom pom tseeb dua thiab xav paub ntau ntxiv. Koj puas to taub nws cov khoom?
