Cov hom lcd zaub yog dab tsi?

Hais txog cov kev qhia hauv lcd, kuv twb tau hais rau nws hauv koob yav dhau los. Tsis ntev los no, qee cov neeg tuaj yeem tau nug txog qhov teeb meem no, vim li ntawd kuv yuav qhia koj txog kev cais ntawm LCD duab hauv kev nthuav dav, thiab nws yuav tsum muab sib sau ua ke rau txhua tus:

Ua ntej, TN lcd zaub

TN hom yog hom uas tau txais los ntawm cov ntsiab lus siv tshuaj tua hluav taws feem ntau, thiab yog siv rau hauv nkag nruab nrab thiab nruab nrab ntawm qhov xaus. Tam sim no, qhov kev ua tau zoo qhia tsis yog ntuj thiab muaj lub ntuj dysentery. Cov TN panels pom ntawm lub khw yog txhua yam tuaj zoo dua TN + zaj duab xis. Cov yeeb yaj kiab yog cov nyiaj xiam oob khab, uas yog siv los ua kom tsis txhob saib lub kaum ntawm TN vaj huam sib luag. Nws hais tias lub TN vaj huam sib luag yog qhov zoo dua rau hauv daim phiaj ua ntej ob sab vim nws tso tawm. Tus naj npawb ntawm cov grey theem loj, thiab cov kua siv lead ua kua molecules deflected ntawm kev kub ceev, kom lub sij hawm teb ntawm cov kua siv lead ua kua molecules tau yooj yim. Tam sim no, cov kua siv lead ua kua ntawm 8 ms lossis tsawg dua ntawm kev ua lag luam yog tag nrho TN panels. Feem ntau, TN vaj huam sib luag yog ib yam khoom nrog cov kev zoo thiab qhov tsis zoo. Tus nqi pheej yig, thiab lub sij hawm teb tuaj yeem ua raws li qhov yuav tsum tau ua kom nws ua tau zoo dua. Hauv cov duab hauv TV, TN saib pom tsis zoo thiab qhov kev ua haujlwm xim tsis muaj tseeb. Obvious disadvantage.

Thib ob, STD lcd zaub

Lub hauv paus ntsiab lus ntawm STN yog zoo ib yam li ntawm TN. Qhov txawv yog hais tias TN cov hauj lwm nematic siv cov kua siv lead ua kua molecules tig qhov teeb pom kev los ntawm 90 degrees, thaum STN super twisted nematic teb nyhuv tig qhov xwm teeb ntawm 180 mus rau 270 degrees.

Peb, DSTN lcd zaub

DSTN scans tus ntswj nematic kua siv lead ua los ntawm ob qho tib si xa kom tiav cov duab. DSTN yog tsim los ntawm Super Twisted Nematic Display (STN). Txij thaum DSTN siv kev siv tshuab ob lub tshuab, cov nyhuv ua kom pom tseeb zoo dua qub rau ntawm STN hauv cov qauv kev qhia hauv lcd.

Plaub, IPS lcd zaub

IPS tseem hu ua lub dav saib dav dav. Nws yog lub vaj huam sib luag technology ua ke los ntawm Hitachi hauv xyoo 2001. Nws tseem raug hu ua "Super TFT." Los ntawm ib txoj kev pom kev, cov kua siv lead ua kua roj ntawm cov pa roj carbon monoxide qhia feem ntau hloov ntawm cov xeev-ntsig-seem, thiab MVA thiab PVA ua kom zoo dua rau hauv txoj kab-bidirectional qaij hloov hom. Qhov sib txawv ntawm IPS technology thiab cov cuab yeej saum toj no lies hauv Nyob rau hauv lub xeev, cov kua siv lead ua kua molecules yeej ib txwm mus rau qhov kev tshuaj ntsuam, tab sis qhov kev taw qhia ntawm kev sib hloov ntawm cov molecules yog txawv hauv hwj huam / ua / xeev - ceeb toom tias kev sib hloov ntawm MVA thiab PVA kua siv lead ua kua molecules belongs rau spatial rotation (Z-axis), thaum IPS kua siv lead ua molecules Cov kev sib hloov yog nyob rau hauv lub dav hlau ntawm kev sib hloov (XY axis). IPS tseem muaj qhov tsis zoo ntawm lub sijhawm teb qeeb. 16.7 M xim, 178 degree saib lub kaum sab xis thiab 16 xuaj moos lus teb sawv cev rau qib IPS LCD zaub hnub no.
