1, Cov qauv yooj yim ntawm LCD npo
Cov ntxaij vab tshaus LCD feem ntau yog tsim los ntawm cov kua siv lead ua kua, cov khoom siv hluav taws xob rov qab, cov phaj polarizing, cov ntxaij lim dej xim, TFT (thin film transistor) arrays, thiab tsav circuits. Cov kua siv lead ua kua yog cov tub ntxhais, nyob nruab nrab ntawm ob lub iav substrates, uas muaj ntau cov kua siv lead ua kua me me uas suav tsis txheeb. Lub backlight module muab lub teeb ci los ua kom pom cov kua siv lead ua kua, tso cai rau cov duab pom. Polarizing daim hlau yog siv los tswj cov kev taw qhia ntawm lub teeb, kom ntseeg tau tias nws dhau los ntawm cov kua siv lead ua kua txheej raws txoj kev uas tau teem tseg. Cov ntxaij lim dej muaj lub luag haujlwm ntxiv cov xim rau cov duab los ntawm kev sib txuas peb lub ntsiab xim ntawm liab, ntsuab, thiab xiav los tsim ntau txhiab xim.
2, Lub hauv paus ntsiab lus ua haujlwm ntawm cov kua siv lead ua kua molecules
Cov kua siv lead ua kua molecules muaj cov khoom uas yog nruab nrab ntawm cov kua thiab cov khib nyiab, thiab lawv tuaj yeem hloov lawv cov kev coj ua raws li qhov kev txiav txim ntawm ib qho hluav taws xob sab nraud. Thaum tsis muaj hluav taws xob hluav taws xob, cov kua siv lead ua kua molecules tau teeb tsa hauv qhov tsis sib xws, thiab lub teeb dhau los ntawm lawv tawg, ua rau lub vijtsam tsaus. Thaum muaj qee lub zog ntawm hluav taws xob hluav taws xob, cov kua siv lead ua kua molecules yuav ua raws li cov kev taw qhia ntawm hluav taws xob, tsim cov kev txiav txim uas tso cai rau lub teeb kom dhau mus, thiab lub vijtsam yuav ci ntsa iab. Txoj kev tswj xyuas qhov kev pom ntawm lub teeb los ntawm qhov hluav taws xob yog lub hauv paus ntsiab lus ntawm kev nthuav tawm cov duab ntawm cov kua siv lead ua kua.
3, Cov txheej txheem tsim cov duab
Kev txais cov teeb liab thiab kev ua haujlwm: Ua ntej, cov duab teeb liab (xws li cov teeb liab video) yog cov tswv yim rau hauv kev tsav tsheb ntawm LCD npo los ntawm kev cuam tshuam (xws li HDMI, USB, thiab lwm yam). Lub voj voog tsav tsheb txiav txim siab thiab ua cov teeb liab, hloov mus rau hauv cov teeb liab digital uas tuaj yeem lees paub los ntawm LCD npo.
Pixel tswj: Lub vijtsam LCD yog tsim los ntawm suav tsis txheeb pixels, txhua qhov sib xws rau TFT transistor thiab cov kua siv lead ua kua cell. TFT transistors ua raws li kev hloov cov ntsiab lus los tswj kev qhib / tawm ntawm cov kua siv lead ua kua sib xws. Thaum lub voj voog tsav tsheb xa cov teeb liab mus rau TFT transistor, TFT transistor yuav qhib lossis kaw, yog li tswj lub zog ntawm lub xeev ntawm cov kua siv lead ua kua cell.
Kev hloov xim thiab ci ntsa iab: Txhua pixel yog them nrog xim liab, ntsuab, thiab xiav xim lim hauv qab chav LCD. Los ntawm kev kho lub zog raws li txoj cai ntawm cov xim LCD sib txawv, qhov siv thiab xim ntawm lub teeb dhau los ntawm pixel tuaj yeem tswj tau, yog li ua tiav cov xim thiab qhov ci ci. Vim qhov tseeb tias tib neeg lub qhov muag pom cov xim los ntawm kev sib xyaw ntawm peb lub ntsiab xim, los ntawm kev tswj qhov sib piv thiab ci ntsa iab ntawm txhua pixel xim liab, ntsuab, thiab xiav thawj xim, cov duab nplua nuj thiab muaj yeeb yuj tuaj yeem nthuav tawm.
Kev ua haujlwm ntawm lub teeb pom kev zoo: Lub teeb ci teeb pom kev zoo muab lub teeb pom kev zoo rau tag nrho LCD npo. Nyob rau hauv qhov tsaus ntuj nti, lub teeb emitted los ntawm lub backlight module yog thaiv los ntawm cov kua siv lead ua txheej, thiab qhov screen tshwm dub; Nyob rau hauv lub teeb ci, lub teeb ci ci los ntawm cov kua siv lead ua kua rau hauv cov xim lim, tsim cov duab zoo nkauj. Txhawm rau txhawm rau txhim kho kev ua tau zoo thiab txo qis kev siv zog, niaj hnub LCD cov ntxaij vab tshaus kuj tau txais ntau yam kev hloov kho lub teeb pom kev zoo, xws li kev hloov kho lub teeb pom kev zoo, muab faib rov qab hloov kho, thiab lwm yam.
4, Txhim kho cov duab zoo
Nrog rau kev nce qib ntawm thev naus laus zis, cov khoom siv thev naus laus zis ntawm LCD cov ntxaij vab tshaus tseem tab tom tsim. Txhawm rau txhim kho cov duab zoo, LCD npo cov tuam txhab tau txais ntau yam kev siv thev naus laus zis, xws li kev daws teeb meem ntxiv (xws li 4K, 8K), nce xim qhov tob (xws li 10 ntsis, 12 ntsis), thiab txhim kho qhov sib txawv (xws li HDR thev naus laus zis) . Nyob rau tib lub sijhawm, txhawm rau txhawm rau daws qhov teeb meem ntawm kev pom lub kaum ntse ntse, kev pom dav dav xws li IPS (In Plane Switching) kuj tau tsim. Kev siv cov thev naus laus zis no ua rau cov txiaj ntsig ntawm cov ntxaij vab tshaus LCD ntau qhov tseeb, muag heev, thiab zoo nkauj.
