Hauv lub ntiaj teb digital niaj hnub no uas thev naus laus zis nkag mus rau txhua yam ntawm lub neej, LCD (Liquid Crystal Display) thev naus laus zis siv yuav luag ib nrab ntawm kev ua lag luam zaub, los ntawm cov xov tooj ntse uas peb siv rau cov yeeb yaj kiab luv luv, mus rau cov khoos phis tawj rau kev ua haujlwm, thiab cov TV rau kev lom zem hauv tsev. Txawm hais tias muaj cov thev naus laus zis zaub tshiab tshwm sim, LCD tseem yog ib feem tseem ceeb ntawm peb lub neej txhua hnub vim nws qhov kev loj hlob, kev ntseeg siab, thiab kev siv nyiaj tsim nyog. Tsab xov xwm no yuav piav qhia txog peb yam tseem ceeb ntawm LCD thev naus laus zis, qhia txog cov lus zais tom qab nws qhov nrov npe.
Txoj Cai Ua Haujlwm thiab Cov Qauv Tseem Ceeb - Cov "Chaw Tseem Ceeb" ntawm LCD
LCD sawv cev rau "Liquid Crystal Display," thiab nws lub hauv paus yog cov khoom siv tshwj xeeb hu ua "liquid crystal," uas muaj nyob rau hauv lub xeev ntawm kua thiab khoom khov. Txij li thaum xyoo 1888, cov kws tshawb fawb tau tshawb pom tias cov molecule liquid crystal tuaj yeem hloov pauv hauv qab lub zog hluav taws xob, ua haujlwm zoo li ntau lub "teeb pom kev me me" kom tswj tau qhov kev hla ntawm lub teeb.
Yuav kom ua tiav qhov kawg ntawm daim duab, lub vijtsam LCD xav tau tsib txheej txheej ua haujlwm sib koom tes kom meej:
Txheej Teeb Pom Kev Tom Qab: Muab lub teeb ci. Cov LCD niaj hnub no feem ntau siv cov teeb pom kev tom qab LED ci dua thiab txuag hluav taws xob ntau dua.
Polarizer: Ua haujlwm zoo li "tus neeg saib xyuas lub teeb," tswj kev co ntawm lub teeb.
Electrode Iav Substrate: Tswj lub kaum sab xis ntawm cov kua siv lead ua kua hauv txhua pixel los ntawm kev siv hluav taws xob.
Txheej Siv Crystal Ua Kua: Lub txheej tswj hwm tseem ceeb, ua haujlwm zoo li "Venetian blinds," kho qhov ntau ntawm lub teeb hla los ntawm kev tig molecular.
Lim Xim: Muab peb lub xim tseem ceeb (RGB) ua ke los tsim cov xim nplua nuj uas peb pom.
Kev ua haujlwm sib koom tes ntawm tsib txheej no tsim lub hauv paus ntawm LCD imaging thiab lub hauv paus rau nws txoj kev ua kom zoo dua ntawm cov duab zoo.
Cov Hom Kev Txawj thiab Kev Txhim Kho Zoo ntawm Duab– Lub LCD Ecosystem Ua Tau Raws Li Ntau Yam Kev Xav Tau
Yuav kom hloov kho rau ntau yam kev siv, LCD thev naus laus zis tau hloov zuj zus mus rau hauv peb hom tseem ceeb:
TN Screen: Paub txog nws lub sijhawm teb sai thiab tus nqi qis, nws yog ib qho kev xaiv rau cov khoom siv ua si, txawm hais tias nws muaj lub kaum sab xis saib nqaim dua thiab kev ua haujlwm xim tsis zoo.
IPS Screen: Muab cov xim zoo heev thiab lub kaum sab xis dav, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov xov tooj ntse thiab cov saib xyuas siab.
VA Screen: Muaj qhov sib piv siab thiab cov xim dub tob dua, ua rau nws nyiam heev rau cov TV thiab cov khoom siv multimedia.
Tsis tas li ntawd xwb, los ntawm kev txhim kho qhov kev daws teeb meem tas li (los ntawm 1080P mus rau 8K), qhov refresh rate (los ntawm 60Hz mus rau 240Hz thiab dhau ntawd), thiab kev koom ua ke HDR (High Dynamic Range) thev naus laus zis thiab cov qauv xim dav dav, qhov zoo ntawm cov duab LCD tau raug txhim kho tas li, muab cov kev pom zoo dua thiab zoo li muaj sia nyob rau kev ua si, video, thiab kev tsim khoom tshaj lij.
Lub zog nyob mus ib txhis ntawm thev naus laus zis laus
Txawm hais tias muaj teeb meem los ntawm cov thev naus laus zis tshiab xws li OLED thiab Mini-LED, LCD tseem tsis tau thim rov qab. Ua tsaug rau nws cov txheej txheem tsim khoom uas paub tab heev, cov txiaj ntsig zoo ntawm tus nqi tsis hloov pauv, thiab kev yooj yim hauv cov ntawv thov loj, LCD tseem txuas ntxiv tswj hwm cov lag luam tseem ceeb xws li TV thiab monitors. Yav tom ntej, LCD thev naus laus zis yuav tswj hwm nws qhov kev sib tw muaj zog hauv thaj chaw tso saib los ntawm kev txhim kho thiab kev tsim kho tshiab, txuas ntxiv muab cov kev daws teeb meem tso saib rau cov neeg siv thoob ntiaj teb.
