Qhov zoo, cov txheej txheem tseem ceeb ntawm cov khoom siv thiab cov haujlwm ntawm cov kua siv lead ua kua

I.introduction rau LCD Zaub

Cov zaub ua kua crystal (LCD) yog ib qho kev nquag ua kua siv lead ua kua crystal zaub ntaus los ntawm nyias {{}} zaj duab xis tranistors. Nws txhawb cov kua siv lead ua cov molecules nrog hluav taws xob tam sim no los ua kev sib xyaw ntawm cov ntsiab lus, kab thiab thaj chaw. Ua ke nrog lub teeb ntawm lub teeb nyob sab nraub qaum, nws nthuav tawm cov duab nplua nuj thiab muaj xim. Nws yog tsim nyog teev tias cov thev naus laus zis xws li qhov zoo, cov txheej txheem tseem ceeb thiab cov haujlwm ntawm cov kua siv lead ua kua.

IPS, TFT thiab SLCD txhua lub caij nplooj zeeg nyob rau hauv qeb ntawm LCD.

, Lossis ua kua siv lead ua cov khoom siv crystal, yog cov khoom siv uas siv cov siv lead ua kua ua cov khoom tseem ceeb. Ua kua Crystal, cov organic tshwj xeeb no, ua kom cov dej ntawm lub xeev ua kua thiab cov khoom siv kho tshiab ntawm cov siv lead ua kom sov. Thaum rhuab, nws yuav tig mus rau hauv cov kua pob tshab. Tom qab txias, nws dhau los ua ib qho crystalline, lub xeev Turbid lub xeev.

Ii. Qhov zoo ntawm LCD zaub

Qhov zoo ntawm cov kua siv lead ua kua muaj peev xwm tseem ceeb. Ua ntej tshaj plaws, qhov zoo ntawm cov ua kua siv lead ua kua muaj xws li lub cev nyias thiab lub teeb noj, tsis muaj hluav taws xob, tsis muaj kev phom sij rau lub qhov muag. Nws lub cev yog cov nyias nyias thiab lub teeb, txuag chaw. Piv nrog rau lub crert saib, nws tsuas yog kom muaj ib - peb ntawm qhov chaw ntawm tom kawg. Thib ob, nws yog lub hwj chim - txuag thiab tsis tsim kom muaj qhov kub thiab txias, ua rau nws qis {fais fab khoom. Piv nrog CRT saib, nws tuaj yeem ua tiav tiav tsis- overheating. Ntxiv rau, nws yog hluav taws xob - dawb thiab muaj txiaj ntsig rau kev noj qab haus huv. Qhov hluav taws xob kiag li {{}} ywj ywj pheej tsim ua rau cov neeg siv kev yooj yim dua.

III.Cov haujlwm thiab cov haujlwm ntawm LCD zaub

Cov kua Crystal zaub ua tiav cov duab zaub los ntawm kev ua kom muaj cov kua roj ua kom muaj hluav taws xob nrog lub teeb hluav taws xob nrog lub teeb ci ntsa iab.

MOOCHROME zaub tiav ua tiav multi {multi} grey} Potizing Ececting cuam tshuam los ntawm kev siv lub xeev ua kua ntawm cov kua siv lead ua kua crystal molecules.

Hauv cov xim zaub, txhua tus pixel muaj cov xim liab, ntsuab thiab xiav.

Muaj tshwm sim ib qho tshwm sim ntawm "kev pom kev sib ntsib" hauv kev pom ntawm dynamic duab los ntawm tib neeg pom kev. Los ntawm kev coj kom zoo dua ntawm cov ntsiab cai no, dynamic cov duab yog li tsim.

Vaj huam sib luag ua kua ua kua yog cov tseem ceeb ntawm LCD zaub, thiab nws cov qauv yog cov khoom siv thiab muag heev. Nws yog tsim ntawm ntau cov khoom siv xws li Pelrizing cov yeeb yaj kiab, iav substrates, matrices dub, cov xim lim, thiab cov yeeb yaj kiab tiv thaiv. Vaj huam sib luag ua kua ua kua yog cov tub ntxhais, suav nrog cov khoom sib xyaw xws li duab polarizing, iav substrates, thiab dub matrices.

Phaj zaj yeeb yaj kiab, tseem hu ua Polarizing zaj duab xis, yog qhov tseem ceeb ntawm cov kua siv lead ua kua. Nws tau muab faib ua ib daim polarizer sab sauv thiab tus lej qis dua. Lub polarization kev ua haujlwm ntawm ob yog sib tshuam rau ib leeg, zoo ib yam li cov muaj nuj nqi ntawm lub laj kab, uas tuaj yeem xaiv lub teeb dej ntas kom dhau mus.

Kev tswj hwm pixel Indient tau tiav los ntawm TFT kev siv tshuab los txhim kho cov lus teb kom ceev thiab duab zoo.

IPS Technology Enhension Saib cov ces kaum thiab kev ua yeeb yam. Qhov kev pom zoo no ua rau cov duab ntshiab dua thiab cov xim muaj tseeb tiag.

SLCD thev naus laus zis txhim kho kev ci ntsa iab thiab sib piv. Lub vaj huam sib luag no ua tiav qhov kev piv siab tshiab los ntawm pob tshab Ito Endment Theem Tsim, yog li surpassing MVA thev naus laus zis ntawm cov zis tawm.

Lub ci ci ntawm LCD saib yog tsuas yog txiav txim siab los ntawm nws cov backlight. Lub chaw teeb pom kev txiav txim siab qhov ci ci, thiab LCDs muaj qhov daws teeb meem.

Chromaticity yog ib qho kev ua tau tseem ceeb ntawm LCD. Daim duab zoo yog ntsuas los ntawm cov tsis xws li cov chromaticity thiab sib piv.

Qhov sib piv yog txhais tau tias yog qhov piv ntawm qhov ci ntsa iab tshaj plaws (txhua tus dawb) rau qhov ci me me (txhua tus dub). Qhov sib piv sib piv ntawm LCD cuam tshuam nrog cov xaiv tswj IC, lim thiab kev qhia ua yeeb yaj kiab thiab lwm yam khoom siv.

Lub sijhawm teb yog qhov tseem ceeb technion ntawm LCD, uas txiav txim siab cov kev paub meej thiab du ntawm cov zaub thaum qhia cov duab dynamic. Lub sijhawm teb kev txiav txim siab qhov smoothness ntawm dynamic duab zaub.
