Cov khoos phis tawj niaj hnub tsis zoo ib yam li cov tshuab qeeb qeeb, uas, txawm li cas los xij, tau ua kom muaj kev hloov pauv hauv thev naus laus zis. Thiab cov saib tam sim no deb deb ntawm cathode ray raj thiab kinescopes. Qhov sib txawv tseem ceeb ntawm txhua tus saib yog hom matrix. Ntawm cov niaj hnub no, feem ntau tuaj yeem hu ua cov saib raws li kua siv lead ua thev naus laus zis. Hauv lus Askiv, qhov no yuav zoo li "Liquid crystal display" (liquid crystal display). Koj tuaj yeem pom lwm cov ntawv luv luv - LCD.
Tseem siv hom TFT matrix. Qhov no yog ib hom kev cuam tshuam cov transistor uas yog siv nyob rau hauv yuav luag tag nrho cov kua siv lead ua kua technologies. Hauv lus Askiv, nws suab zoo li "thin-film transistor" (feem ntau luv luv rau cov ntawv luv TFT) Yog li, peb tuaj yeem hais tias feem ntau LCD saib kuj yog TFT saib.
Tab sis txawm nyob ntawm no muaj qhov hloov pauv. Hom matrix txiav txim siab ob qho tib si duab thiab kev ua haujlwm. Yog li ntawd, nws tsim nyog nyob hauv kev nthuav dav ntxiv ntawm hom nrov tshaj plaws.
Cov cuab yeej qub tshaj plaws tuaj yeem suav tauTwisted Nematic (los yog tsuas yog TN). Txog rau hnub tim, nws tau raug suav hais tias yog ob qho tib si pheej yig tshaj plaws thiab feem ntau. Xav txog nws txoj kev yooj yim, hom matrix no tsis tu ncua, txhim kho, ua kom zoo dua thiab pheej yig dua. Ib puag ncig tshiab hauv kev txhim kho Twisted Nematic thev naus laus zis yog txheej txheej ntxiv uas ua rau kom pom lub kaum sab xis ntawm lub monitor. Qhov no feature hu ua "Film". Lub ntsiab kom zoo dua ntawm qhov kev tsim kho tshiab no tuaj yeem hu ua tus nqi qis, uas tau los ua lub hauv paus ntawm nws qhov chaw, nrog rau lub sijhawm teb tsis tshua muaj, uas tso cai rau koj los saib cov yeeb yaj kiab dynamic ntawm cov saib no (nws tsis yog qhov nyuaj rau twv tias qhov no yog. vim li cas hom tn matrix no hu ua "Film".)
Txawm li cas los xij, TN muaj qee qhov tsis zoo. Piv txwv li, nws muaj cov xim tsis zoo thiab muaj qhov tshwm sim ntau uas cov subpixels tsis zoo yuav tshwm sim ntawm qhov screen. Yog li ntawd, cov saib no feem ntau siv hauv chaw ua haujlwm lossis siv hauv tsev nrog kev siv nyiaj tsawg.
Lwm cov thev naus laus zis nrov yog IPS, uas tau koom ua ke tsim los ntawm Hitachi thiab NEC. Lub luag haujlwm tseem ceeb ntawm kev txhim kho yog qhov no: txhawm rau tshem tawm qhov tsis txaus ntawm TN-TFT. Nrog kev pab los ntawm lawv IPS, cov neeg tsim khoom muaj peev xwm ua kom pom lub kaum ntse ntse, daws qhov teeb meem nrog cov xim luam tawm thiab sib piv. Txawm li cas los xij, lawv tsis tuaj yeem zam qhov tsis zoo: lub sijhawm teb tau nce ntxiv. Tus nqi rau cov saib yog ib txwm siab dua rau TN TFT.
Lwm cov thev naus laus zis thev naus laus zis yog IPS-S. Tsab ntawv S ntawm no yuav tsum txhais lo lus"super". Cov hom matrices no yuav tsum daws qhov teeb meem nrog saib cov ces kaum thiab nce lub sij hawm teb ntawm pixels. Qhov twg, qhov tseeb, cov neeg tsim khoom ua tiav tiav. Cov hom kev saib no feem ntau siv rau kev ua si, kev tshaj tawm thiab cov duab kos duab, kev ua qauv qhia.
Muaj ob peb lwm yam subtypes ntawm IPS thev naus laus zis. Cov no yog Kab rov tav, Ultra Kab rov tav thiab kev tshaj lij. Lawv tau hloov kho versions ntawm IPS panels thiab muaj qee qhov zoo, tab sis kuj yog tus nqi siab dua. Piv txwv li, cov txiaj ntsig ntawm cov subtypes xws li qhov sib txawv ntxiv, txhim kho cov duab pom cov ces kaum, qib siab xim rendering.
