Yog li thaum peb xav yuav lub LCD saib zoo, peb yuav tsum muaj qee qhov kev nkag siab ntawm LCD vaj huam sib luag, uas cuam tshuam ncaj qha rau qhov ci thiab xim ntawm cov zaub. Cov khoom siv hluav taws xob tam sim no tau txhim kho sai heev, thiab txhua tus neeg yuav tsum paub tias cov tuam txhab tseem ceeb ntawm LCD panels yog Samsung, LG, Philip, thiab AUO. Cov thev naus laus zis thiab qib sib txawv, thiab qhov zoo ntawm cov vaj huam sib luag tsim tau yog qhov sib txawv. Cov vaj huam sib luag tam sim no muaj xws li: TN panels, MVA panels, PVA panels, VA panels, IPS panels thiab CPA panels.
1. TN hom vaj huam sib luag
TN: Twisted nematic vaj huam sib luag, nws cov nqi ntau lawm tsis siab, tab sis nws yog ib hom vaj huam sib luag nrog cov lus teb zoo dua hauv kev ua lag luam, thiab nws tau siv dav. Qhov peb pom ntawm kev ua lag luam tam sim no yog nws cov kev hloov kho dua tshiab, uas yog, ib hom yeeb yaj kiab ntxiv, hu ua zaj duab xis them nyiaj. Raws li lub npe qhia, nws yog siv los sau qhov tsis txaus ntawm lub kaum sab xis saib ntawm TN vaj huam sib luag. Lub ntsiab kom zoo dua ntawm TN vaj huam sib luag: lub deflection ceev ntawm cov kua siv lead ua kua molecules yog ceev heev, yog li lub sij hawm teb yog zoo dua.
2. VA hom vaj huam sib luag
VA panels tau siv nyob rau hauv high-end LCD panels. Nws yog lub vaj huam sib luag pom dav. Piv nrog TN panels, nws cov nqi kuj yog siab heev, thiab nws yog cov khoom siv high-end. Nws tus yam ntxwv yog tias sab pem hauv ntej (pem hauv ntej saib) ntawm VA vaj huam sib luag muaj qhov sib txawv siab tshaj plaws, tab sis cov zaub tsis sib xws, thiab xim feem ntau hloov.

Thaum peb tus ntiv tes kov nws maj mam, nws yuav pom cov qauv plum. Qhov zoo dua yog qhov pom lub kaum ntse ntse yog qhov loj, thiab cov xim luam tawm yog qhov tseeb. Qhov tsis zoo yog tias lub zog siab dua thiab lub sijhawm teb kuj qeeb.
3. IPS vaj huam sib luag
IPS: Nyob rau hauv-dav hlau hloov tshuab, nws yog kua siv lead ua vaj huam sib luag tshuab tsim los ntawm Hitachi hauv 2002. Nws yog hu ua" SuperTFT". Tab sis peb tsis tshua muaj nyob rau hauv kev ua lag luam, thiab muaj ob peb qauv. Nws ob tug ncej yog nyob rau tib qhov chaw, uas yog qhov loj tshaj feature uas txawv nws los ntawm lwm yam panels. Vim hais tias cov electrodes nyob rau tib lub dav hlau, cov kua siv lead ua kua molecules ib txwm nyob rau tib lub sijhawm rau lub vijtsam txawm tias lub xeev twg, uas yuav txo qhov aperture piv. , Txo cov teeb pom kev zoo, yog li IPS daim ntawv thov ntawm LCDTV yuav xav tau ntau lub teeb rov qab. S-IPS vaj huam sib luag yog ib hom kev txhim kho ntawm IPS. Nws qhov zoo yog qhov pom lub kaum ntse ntse, cov lus teb ceev ceev, thiab tus nqi qis. Qhov tsis zoo yog tias lub teeb xau yog qhov hnyav dua, qhov purity ntawm cov xim dub tsis yog raws li tus qauv, thiab yuav tsum muaj cov yeeb yaj kiab kho qhov muag los hloov nws. Thaum peb saib lub vijtsam kom zoo, yog tias peb pom ntses- nplai pixels tig mus rau sab laug, ntxiv rau lub vijtsam nyuaj, ces peb tuaj yeem paub tseeb tias nws yog IPS vaj huam sib luag.
4. CPA vaj huam sib luag (ASV vaj huam sib luag)
CPA: (Nruam foob pob hluav taws) hom dav saib lub kaum ntse ntse thev naus laus zis (soft screen), nws yog ib hom VA, nws cov kua siv lead ua kua molecules tab tom ntsib lub hauv paus electrode, zoo ib yam li cov foob pob hluav taws. Lub teb hluav taws xob saum toj ntawm pixel electrode kuj tseem hloov pauv tas li, yog li qhov kev pom dav dav no tseem hu ua" txuas ntxiv foob pob hluav taws" hom. CPA yog txhawb nqa los ntawm Sharp. Nws yog ib tug dav-saib tshuab tsim los ntawm lawv. Sharp' s CPA vaj huam sib luag muaj ntau cov xim tiag tiag, saib lub kaum ntse ntse, thiab cov duab ilv, tab sis tus nqi yog kim dua, thiab Sharp tsis tshua muaj qhov sib piv rau lwm tus neeg muag khoom CPA panels. Lub CPA vaj huam sib luag kuj belongs rau lub vijtsam muag. Cov qauv dej zoo sib xws yuav tshwm sim thaum koj maj mam los so nrog koj txhais tes. Cov vaj huam sib luag no yog TFT vaj huam sib luag, tab sis tam sim no txhua yam ntawm cov vaj huam sib luag muaj lawv tus kheej cov yam ntxwv thiab cov qauv tsim, thiab muaj cov npe sib txawv. , Yog li TFT tsis tshua hnov hauv khw.
