Tom qab defeating CRT, LCD tshuab tau ua huab tais undisputed ntawm cov lus teb rau ze li ntawm 20 xyoo. Thaum lub Kaum Hlis 2013, Panasonic tshaj tawm tias cov kev ua lag luam plasma las yog xaus rau thaum lub Peb Hlis 2014. Ib lub sijhawm tas lawm, thiab keeb kwm lub teeb meem LCD tau siv los ntawm OLED.
Ntawm lub LCD mus rau OLED, cov lus satirical dynasty hloov
Ironically, lub planar LCD tshuab hloov cov nkhaus CRT cathode duab tshav raj 20 xyoo dhau los; 20 xyoo tom qab, lub LCD tseem yog ib qhov txuj ci ntawm tshuab curved - OLED (Lub Teeb Duab Hluav Taws Xob Emitting Diode).
Thaum pom CES hauv lub xyoo 2013, lub ntiaj teb thawj curved TV tau pib los ntawm LG. Dab tsi ntau ironic yog tias, ib yam li cov neeg lag luam thiaj li yuav cia cov CRT txuas ntxiv, "imitation" tiaj tus vaj huam sib luag LCD launched ib daim duab CRT siab, kom tswj tau nrog cov fascinating OLED, Sony launched lub ntiaj teb thawj curved LED TV hauv lub tib lub xyoo.
Technology yog siab phem, LCD LCDs tau raug ntaus CRT, tab sis LCDs yuav ntxov los yog tom qab hloov tau los ntawm lwm cov technologies. Tab sis ua ntej yuav tau hloov, manufacturers yuav txuas ntxiv mus qhia cov khoom hloov mus rau tus thawj LCD kab. Yog vim li cas rau thawb lub LCD mus rau forefront yog sim los txeeb cov nkhaus LCD TV uas yog keeb kwm los ntawm cov lag luam OLED.
OLED TV qauv
Dong Shi nyhuv, vim li cas cov ntxhuav LCD yuav tsum tsis txhob muab ua rau hauv qhov chaw nto curved?
Cov ntaub ntawv nkhaus yuav muab sib piv rau ib tus neeg siv loj dua qhov kev pom, txhim kho qhov kev pom zoo, thiab lub TV nkhaus muaj ntau tsos tsis pom kev. Yog li ntawd, nws yog ib qho yooj yim los ua ib tus curved OLED, thiab nws tau raug tsim los ua ib lub TV hauv OLED los ntawm LG. Tab sis qhov qub tshaj plaws yog muab tso rau hauv LCD yog kom zoo.
Lub hauv paus ntsiab lus thiab cov qauv ntawm LCD kua siv lead ua los kuj nyuaj. Nws tswj cov kua siv lead ua kua molecules tig los ntawm qhov ntsuas, qhov no thaiv cov teeb nrig kom tswj tau qhov tob xim (grayscale ci ntsa iab), thiab tom qab ntawd cia qhov txawv sub-pixels los tso saib peb lub ntsiab xim los ntawm cov phom polarizing thiab cov lim, xim thiab qhov tob ntawm qhov controllable sub-pixel ntsiab lus yuav muab tau. Txawv cov dluab yog tso tawm kom pom hauv pixel array.
TN, IPS, MVA, thiab PVA panels uas txhua leej txhua tus feem ntau yog mloog yog TFT-tsav LCD ntsuas. Qhov txawv yog qhov kev tsim cov kua siv lead ua kua molecules. Hauv cov qauv tseeb, cov kua tshuaj ua kua xeb tseem ceeb ntawm ob lub tsom iav los ntawm kev siv hluav taws xob los ntawm TFT (Thin Film Transistor).
Rau txhua tus taw tes ntawm sub-pixel, cov kua siv lead ua kua yog lub luag hauj lwm rau kev tswj cov grey nplai, thiab peb thawj xim cov ntxaij lim dej tswj cov xim, thiab lawv yuav tsum nyob rau hauv ib-rau-ib tsab ntawv los nthuav cov xim kom yog. Yog hais tias cov kua hluav taws xob hauv lub kav dej yog cov nyhav, lub sab nraud yuav me dua cov txheej txheem sab nraud, thiab thawj ib leeg rau cov kua ua kua thiab lub lim yuav muaj qhov sib txawv ntawm qhov sib txawv, uas ua rau cov xim txawv txawv. Lwm cov kev mob tshwm sim muaj xws li lub nrig qis, tsaus nti duab ntxoov ntxoo, thiab daus paj.
