LCD ua haujlwm li cas?
Dab tsi yog qhov ua haujlwm ntawm txoj kev ntsug thiab kab rov tav substrate, yog tias muaj kev xav paub ua kua, tab sis nws cov lus teb tag nrho, tab sis nws cov duab qhia txog cov roj ntsha (LCD): Ntxiv rau LCD, ntau hom ntawm 9 teev, Panels yog siv nyob rau hauv ntau yam duab hluav taws xob, xws li LCD saib, LPR TVs, laptop Screens. Txawb xov tooj. tus lwm yam
LCD Panels tau siv dav hauv cov khoom siv allthes, khaws cia rau hauv siab lub zog yuav khoom siv zog ntawm cov neeg. Yog li, peb xub sim
Kawm cov txheej txheem ua haujlwm ntawm cov kua siv lead ua kua.
Feem ntau, cov kua ua kua crystal zaub yog tsawg dua li ob lub qog tuab. Kuj ceeb tias, cov iav no iav nyias muaj rau sab hauv. Yog li ua ntej, koj yuav tsum paub cov npe ntawm cov npe no rau cov substrates- (phim rau txheej rau txheej hauv qab no nrog daim duab saum toj no)
1.led backlight (lub teeb ci)
2.Vhawb puab polarizer (ntsug polarizing lim)
3.Qhov zaj duab xis transistor substrate (TFT Matrix)
4.Kev muaj cov muaju substrate.
5.RGB Xim Lim.
6.Hoghizontal polarizer (kab rov tav polarizing lim).
7.glass npog.
Los ntawm cov npe saum toj no, peb tau paub txog cov npe ntawm cov txiv kab ntxwv ntawm LCD vaj huam sib luag. Tam sim no, peb yuav ua siab ntev todo to taub txoj haujlwm ntawm txhua substrate lossis li cas cov kua crystal zaub ua haujlwm
1. Backlight
Txoj kev ua haujlwm ntawm Backlight ntawm LCD yog dab tsi? Lub Backlight yog lub teeb ci ntawm cov liqustal zaub vaj huam sib luag. Qhov Backlight yog qhov teeb meem ntawm lub teeb rau cov ITOTHAT tshwm sim ntawm LCD TVS, laptop qhia, saib xyuas cov xov tooj ntawm tes. Smartphone deals
Nyob rau hauv cov kev thev naus laus zis tshiab tshaj plaws, LCD Panels 'teeb qhov chaw yog LED Backlights muab cais nyob hauv qab ntawm lub vijtsam. Inthin Displavs, Led Strips tau muab tso rau ntawm cov npoo ntawm lub teeb-ua iav. Kuj, cov qauv qub qauv qhia siv high-voltagefluorescent txoj hau raws li lub teeb ci
2.Vhawb cov polarizer
Tus lej ntsug ua dab tsi hauv LCD?
COLARIER yog dab tsi? Tus polarizer tsis yog hluav taws xob sib xyaw. LT yog ua los ntawm PVA (polyvinyl cawv), ib tug polarizing fillsheet.or lub lim polarizing rau LCD panels.
Raws li lub teeb los ntawm lub backlight dhau los ntawm LCD vaj huam sib luag, nws ntsib lub cev polarizing. Cov lim no tsuas yog tso cai rau cov teeb pom kev hla dhau, oscillating nyob rau hauv ib qho kev taw qhia tshwj xeeb. Qhov no pab kom lub teeb yog polarized ua ntej cuam tshuam nrog theliquid muaju.
Tus lej ntsug hauv LCD (ua kua Crystal zaub) VAJ HUAM SIB TEEB MEEM LOS NTAWM ntau cov txheej txheem ntawm lub teeb, 9 ua kua Crystal Molecules, los tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab, kom tsim cov duab kos duab.
Cov polarizer ntsug tso cai rau lub teeb tsis muaj txiaj ntsig zoo kom dhau los ntawm thaum thaiv cov oscillatinghorizontly.
Qhov kev tswj hwm no ntawm lub teeb yuav pab tswj cov kev qhia ua kua crystal molecules txwv tsis pub muaj koj lub qhov muag, tsim cov duab thiab hues uas koj pom ntawm tus mob.
3. TFT (nyias zaj duab xis transistors) substrate
TFT thiab nws txoj haujlwm hauv LCD yog dab tsi?
Lub TFT nyias-zaj duab xis transistor) substrate yog qhov tseem ceeb hauv LCD Technology. Nws pabcuam ua lub hauv paus lossis theem pib txheej rau thethin-zaj duab xis transistors uas tswj tus neeg pixels ntawm cov zaub. Lub subt deg substrate yog feem ntau ua los ntawm iav thiab dogated nrog cov khoom siv nyias ntawm cov ntaub ntawv subiconductor, xws li kev tswj hwm tus kheej ntawm txhua tus pixel ntawm lub lcd npo. Txhua tuspixel muaj kua crystal baster sandwiched ntawm ob txheej ntawm iav. Cov tfts ntawm txheej txheem kev ua yeeb yam uas tswj hwm tus siv lead ua kua muag, txiav txim siab nws lub xeev kho qhov muag (yog tso cai rau lub teeb lossis thaiv nws).
