Kev sib piv ntawm cov yam ntxwv ntawm cov neeg saib xyuas

CRT yuav luag tag nrho ntawm lub ntsiab nta zoo heev, qhov teeb meem yog tias qhov screen me me, loj thiab hnyav;

Kev ua tau zoo ntawm LCD tau raug ua kom zoo dua nyob rau hauv xyoo tas los no, thiab lub ntsiab ua yeeb yam ze rau CRT, tab sis qhov kev ceev ceev thiab lub kaum sab xis pom yog me ntsis zuj zus;

PDP fais fab siv, kev ua haujlwm tau zoo tsis siab;

Lub ntsiab ntawm OLED zoo heev, tab sis lub neej ntawm lub cuab yeej thiab kev paub tab ntawm cov txheej txheem tsim yuav tsum raug kho;

LED vim nws txoj kev ci ntsa iab, muaj peev xwm siv tau rau sab nrauv loj.


Kev loj hlob keeb kwm ntawm cov kua siv lead ua kua thiab kua tshuaj siv ua kua

1 Kev loj hlob ntawm kua muaju

1854 Lyotropic kua siv lead ua kua txig

1888 Cov kua ntxhuab cov thermotropic raug xub tau pom los ntawm Austrian botanists

Lehmann, ib tug German physicist, qhia tias cov kua, kua khoom muaj crystalline zog thiab muaj npe nws kua muaju.

2 Txheej txheem LCD tsim

1964 Xov Tshoj Xov Xwm Hauv Tebchaws Asmeskas (RCA) pom tias tus qauv (GH)

Dynamic scattering hom (DSM) thiab theem hloov qauv tau pom nyob rau hauv tib lub xyoo

1968 RCA tshaj tawm lub hnub yug ntawm lub ntiaj teb thawj zaug --LCD, tus qauv siv rau kev tawg paj nruag (DSM)

Xyoo 1971 Swiss ROCHE tau tsim cov khoom sib txig nematic ua kua (TN - LCD), tus qauv uas tseem niaj hnub siv, xws li TFT - LCD cov khoom, uas tseem siv.

1984 Swiss SCHEFFER ua tus qauv SBE, thiab Nyiv tuaj yeem ua tus qauv SBE kom tau cov qauv STN thiab tau siv nws. Cov qauv no, zoo li TN qauv, los ua ib feem ntawm cov qauv siv ntau tshaj plaws niaj hnub no

1971 RCA npaj lub tswv yim ntawm lub tshuab matrix tsav tsheb, uas yog lub hauv paus ntawm AM - LCD.

1981 Lub Tsev Kawm Ntawv DUUDEE hauv ntiaj teb rau thawj zaug tau zoo tsim tau 5X7 dot matrix TFT - LCD.

1986 Panasonic tau pib muaj 3 nti xim LCD TV.

1991 A 10 nti xim TFT - LCD laptop tshwm.

1993 TFT - LCD nkag hauv qhov ntau lawm theem, .2005 hauv 1 lub hlis twg, Samsung Electronics tsim eighty-two inch LCD TV

TFT - LCD tau dhau los ua tus neeg hauv tsev LCD tshaj ntawm qhov hnyav, qhov loj tshaj plaws cov khoom tso tawm ntawm qhov khoom.

Nyob rau lub sijhawm no, hluav taws xob tswj cov tshuaj tiv thaiv, ECB, kua tshuaj ua kua (PDLC) siab, hloov pauv kua tshuaj (PC), cov dej ua kua (ferroelectric liquid Crystal) (FLC) hom zaub tau yug.
