LCD zaub tau nyob rau hauv kev ua lag luam rau ze li ntawm 10 xyoo, thiab nws tau hloov tag nrho cov tsoos CRT zaub thiab tau dhau los ua qhov tseem ceeb ntawm kev ua lag luam. Cov qauv ntawm LCD yog muab cov kua dej tso rau ntawm ob qho tib si ntawm cov iav. Muaj ntau cov kab me me ntsug thiab kab rov tav ntawm ob daim iav. Cov pas nrig-shaped crystal molecules raug tswj kom hloov cov kev taw qhia los ntawm kev siv hluav taws xob los yog tsis siv rau refrac lub teeb los tsim cov duab. Nws muaj kev pab cuam lub neej ntev dua li CRT, kev siv hluav taws xob qis dua thiab tus nqi qis dua. Yog li dab tsi txiav txim siab qhov ci ntawm LCD zaub? Tus editor ntawm Zhilingxin yuav qhia rau koj.
Dab tsi txiav txim siab qhov ci ntawm LCD zaub:
Raws li peb txhua tus paub, LCD qhia cov duab tam sim no los ntawm lub teeb pom kev tshwj xeeb, thiab kev ua haujlwm ntawm lub teeb pom kev zoo kuj muaj qhov cuam tshuam tseem ceeb rau qhov ci ntawm cov zaub, yog li qhov ci ntawm LCD zaub nyob ntawm qhov chaw teeb pom kev zoo xwb.
Tom qab lub teeb rov qab emits lub teeb, lub teeb yog tswj los ntawm qhov voltage ntawm lub pem hauv ntej LCD zaub vaj huam sib luag, thiab cov kua siv lead ua kua molecules tso cai rau lub teeb hla los yog daim npog qhov ncauj los tso saib lub brightness ntawm daim duab. Cov txheej txheem no yog tswj hwm los ntawm IC nti, uas zoo ib yam li lub hauv paus ntsiab lus rau lub kaw lus hauv lub koob yees duab thiab tuaj yeem tswj tau lub luminous flux. Cov khoom siv lub koob yees duab feem ntau yog nruab nrog lub kaw lus nyob rau sab nraum qab ntawm lub lens, thiab lub kaw lus qhib thaum tua, tso cai rau cov khoom kom pom hauv zaj duab xis lossis cov khoom siv photosensitive los tsim cov duab. Tsis tas li ntawd, lub vaj huam sib luag kua siv lead ua emits lub teeb nrog qhov sib npaug ntawm lub teeb ci, uas yog thaiv / tswj los ntawm lub teeb ntawm lub vaj huam sib luag kua siv lead ua, thiab yog cov duab los ntawm lub teeb thiab duab ntxoov ntxoo ntawm lub teeb.
Thaum saib cov duab ntawm LCD saib lossis LCD TV, koj yuav pom tias lub teeb dhau los ntawm LCD vaj huam sib luag tsis tsuas yog tshwm nyob rau hauv daim ntawv ntawm lub npe thiab qhov tsaus ntuj, tab sis kuj muaj ntau yam xim ntawm lub teeb mus rau qhov tsaus ntuj. Tsis tas li ntawd, thaum peb tsis tu ncua saib ib qho animation, tus qauv yog tias peb xav tau 60 duab ib ob, uas yog, lub teeb thiab tsaus ntuj hloov pauv 60 zaug ib ob. Txhawm rau tso cov duab kom raug, yuav tsum muaj pixels txaus. Cov qauv ntawm cov kua siv lead ua kua yuav tsum zoo txaus. Los ntawm qhov kev xav no, high-end LCD panels thiab cov khoom qis kawg yuav txawv ntawm qhov kev hwm no, uas kuj yog ib qho ntawm cov laj thawj rau tus nqi sib txawv.
LCD saib tuaj yeem siv qhov hluav taws xob los tswj lub teeb ci ntawm kev kub ceev, tab sis txij li lub vaj huam sib luag LCD tuaj yeem tswj lub teeb thiab duab ntxoov ntxoo, qhov no tsuas yog siv tau rau cov duab dub thiab dawb xwb. Yog tias koj xav tso cov duab xim, koj kuj yuav tsum tso cov xim lim rau pem hauv ntej ntawm cov kua siv lead ua kua molecule txheej kom ntxiv xim rau lub teeb ci thiab tsaus. Yog li ntawd, ntxiv rau qhov ci ntsa iab ntawm lub teeb pom kev ntawm nws tus kheej, kev tswj cov kua siv lead ua kua molecules los ntawm IC nti (kev ua haujlwm rau / tawm), qhov zoo ntawm cov kua siv lead ua vaj huam sib luag nws tus kheej, qhov piv ntawm aperture thiab lub teeb transmittance, thiab lwm yam. txhua tus yuav muaj qee yam cuam tshuam rau qhov ci ntawm cov kua siv lead ua kua.
