Saib Cov Txiaj Ntsim

Niaj hnub nim no cov computers tsis nyob txhua yam li cov tshuab cumbersome qeeb, uas, li cas los xij, tau tsim ib lub kiv puag ncig hauv tshuab. Thiab saib tam sim no nyob deb muab tshem tawm los ntawm cathode txoj sab ci hlab thiab TV hlab. Qhov loj sib txawv ntawm txhua tus saib yog hom ntawm hom ntawv. Ntawm cov niaj hnub no feem ntau yog cov saib raws le kua hluavtaws ua kua. Nyob rau hauv lus Askiv nws yuav sound zoo li "lub kua uas siv lead ua zaub" (LCD). Feem ntau koj tuaj yeem pom lwm qhov txo - LCD.

Hom kev hloov hauv cov duab thin-film transistors kuj yog siv. Qhov no zoo ntawm teb-nyhuv transistor, uas yog siv nyob rau hauv txhua technology ntawm cov kua siv lead ua qhia. Nyob rau hauv lus Askiv nws suab zoo li "nyias-zaj duab xis transistor" (feem ntau yog zog rau acronyms TFT) Yog li ntawd, peb yuav hais tias feem ntau ntawm cov LCD-saib thiab ib tug TFT-saib.

Tab sis txawm no muaj ntau ntau yam sib txawv. Hom matrix pom cov duab thiab kev ua haujlwm. Yog li ntawd, nws yog ib qho muaj nqis ntau tshaj plaws nyob rau hauv hom nrov tshaj plaws.

Cov cuab yeej ua haujlwm qub dhau los yuav pom tau tias Twisted Nematic (los yog TN xwb). Mus rau hnub tim, nws yog zoo raws li qhov pheej yig heev, thiab feem ntau ntau. Vim nws simplicity, hom no ntawm matrix yog tas li evolving, kev txhim kho, ua zoo dua thiab pheej yig. Ib tug tshiab twist nyob rau hauv kev loj hlob ntawm Twisted Nematic technology yog ib qho ntxiv txheej uas tsub kom pom lub kaum sab xis ntawm lub monitor. Qhov no feature hu ua "Zaj Dab Neeg". Lub tswv yim zoo tshaj plaws ntawm qhov kev hloov no tuaj yeem hu ua tus nqi qis, uas yog lub hauv paus ntawm nws qhov chaw, nrog rau lub sijhawm tsis muaj kev ywj pheej, uas tso cai rau cov yeeb yaj kiab hauv cov kev ntsuas no (nws tsis yooj yim twv tias qhov no yog hom ntawv matrix tn hu ua "Film").

Tiam sis, TN muaj qee qhov teeb meem. Piv txwv li, nws muaj cov xim tsis zoo thiab qhov yuav ua rau cov neeg tsis muaj teeb meem tshwm sim hauv qhov screen. Yog li ntawd, xws li cov neeg saib xyuas no feem ntau siv rau hauv chaw ua haujlwm lossis hauv tsev siv nrog rau siv nyiaj tsawg.

Lwm cov tshuab fais fab yog IPS, uas tau koom tes tsim los ntawm Hitachi thiab NEC. Lub ntsiab haujlwm ntawm txoj kev loj hlob yog qhov no: rhuav tshem ntawm qhov tsis zoo ntawm TN-TFT. Nrog kev pab ntawm nws cov IPS, cov neeg tsim khoom tsim muaj peev xwm nce lub zeem muag pom, daws qhov teeb meem nrog kev luam xim thiab sib txawv. Txawm li cas los xij, peb tsis tuaj yeem tsis muaj qhov tsis zoo: lub sijhawm teb nce. Tus nqi rau cov neeg saib xyuas zoo li no, yeej yog siab dua TNT TFT.

Lwm lub tshuab tshiab yog IPS-S. Tsab ntawv S yuav tsum yog lo lus "super". Cov matrices yuav tsum tau daws qhov teeb meem nrog saib cov ces kaum thiab ua rau kom lub pixel teb lub sij hawm. Dab tsi, qhov tseeb, cov neeg tsim khoom tau ua tiav hlo. Cov hom kev saib xyuas zoo li no feem ntau siv rau kev ua si, ua cov ntxig rau cov duab thiab cov duab nraaj, kev qhia tawm ntawm cov haujlwm.

Muaj ntau ntau qhov kev siv IPS technology. Qhov no yog Horizontal, Ultra Horizontal thiab Kev. Lawv hloov versions ntawm IPS matrices thiab muaj ib co zoo, tab sis nyob rau tib lub sij hawm ib tug ntau dua tus nqi. Piv txwv, qhov zoo ntawm cov subtypes zoo li no muaj kev sib txawv dua, kev saib xyuas cov ces kaum, kev ua kom muaj xim loj.
