Xaiv lub TV tshiab, tus neeg yuav khoom tau ntsib nrog cov lus nug, uas yog ib qho zoo dua: LCD lossis "ntshav"? Yog hais tias LCD TVs kim dua, puas yog txhais tau tias lawv tau zoo dua li pheej yig cov ntshav TVs?
Dab tsi yog qhov sib txawv ntawm LCD thiab ntshav TVs: kev tshawb xav
Tsoos TVs nrog cov duab lub lauj kaub thiab lub raj, qhov tseeb, twb dhau los ua ib feem ntawm keeb kwm. Tam sim no ntawm kev ua lag luam TV hauv lub pob yog tswj hwm los ntawm cov kua siv lead ua thiab cov plasma ntshav. Nyob rau tib lub sijhawm, tus nqi "ntshav" yog qis dua tus nqi ntawm LCD TV. Tab sis puas kim dua ib txwm txhais tau tias zoo dua? Lo lus teb rau lo lus nug no tau ua nrog TV tsim thev naus laus zis.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov ntshav plasma vaj huam sib luag yog li nram qab no. Qhov chaw nqaim ntawm ob lub pob tshab yog qhov uas muaj cov roj tshwj xeeb. Kuj tseem muaj kab sib txuas ntawm cov xaim hluav taws xob los ntawm kev hluav taws xob tam sim no. Thaum lub TV qhib, hluav taws xob hloov lub roj nkev mus rau hauv ntshav, uas ua rau cov fluorescent ntsiab ci. Nov yog cov duab tsim.
LCD TVs yog qhov sib txawv kiag li. Daim duab ntawm lub vijtsam yog tsim los ntawm cov kua siv ua kua uas hloov kho lub teeb uas ci tuaj ntawm lub teeb tom qab. Cov kua muaju, nyob ntawm qhov hluav taws xob hluav taws xob, dhau ib qho lossis lwm qhov ntawm lub teeb hluav taws xob dhau ntawm lawv tus kheej.
Yuav ua li cas yog cov yam mus nyob rau hauv kev xyaum?
Yuav ua li cas cov kev qhia thev naus laus zis qhia lawv tus kheej hauv kev coj ua, thiab dab tsi yog qhov zoo ntawm cov nqi hluav taws xob ntau hauv TVs piv rau "plasmas", uas yog pheej yig dua? Ua ntej, txog thaum nyuam qhuav tas, kev tsim cov TV LCD nrog cov kab pheeb ces kaum ntau dua 32 ntiv tsis tau. Tam sim no cov tuam txhab lag luam tau kawm yuav ua li cas ua cov LCD loj-cov lus, tab sis cov thev naus laus zis nws nyuaj thiab kim.
Nrog "plasmas" qhov xwm txheej yog qhov fab ntxeev: thev naus laus zis tsis tso cai rau tsim cov plasma vaj huam sib luag nrog cov kab pheeb ces me me. Ntawm qhov tod tes, kev tsim cov xov tooj cua TV nrog cov kab pheeb ces kaum ntau dua 32 ntiv taw yog pheej yig dua piv rau LCD TV ntawm tib qho loj.
Nyob rau lub sijhawm tam sim no, tus nqi ntawm LCD panels yog nyob rau nruab nrab 25% siab dua, uas yog qhov laj thawj tseem ceeb rau tus nqi siab dua ntawm cov TVs txheeb ze rau cov plasma panels. Hauv kev coj ua, "plasmas" yeej muaj ntau yam, txawm hais tias LCD TV kuj tseem muaj lawv qhov zoo, txwv tsis pub yuav tsis muaj qhov taw tes hauv kev tsim lawv.
Ib qho ntawm qhov tseem ceeb ntawm LCD TVs yog lawv lub zog noj qis: lub plasma xav tau ob zaug ntau npaum li hluav taws xob ua haujlwm. Ntxiv rau, cov ntshav TV TV tau kub heev thaum lub sijhawm ua haujlwm, yog li lawv yuav tsum tau nruab nrog cov tshuab pa tshwj xeeb uas tsim muaj suab nrov ntxiv. Tsis tas li ntawd xwb, vim tias muaj kev phom sij ntawm kev ua kom muaj zog, nws tsis muaj kev nyab xeeb los tso lub plasma TV hauv niches. Lwm qhov zoo dua ntawm LCDs yog lawv cov kev pabcuam lub neej: lawv muaj lub sijhawm nruab nrab 80,000 teev, uas yog ob zaug ntev npaum li qhov "ntshav".
Raws li rau cov duab zoo, ntawm no LCD yog qis dua "ntshav". LCD tsis tso tawm lub teeb, tab sis kis nws los ntawm cov kua muaju, yog li ntawd daim duab yog qhov pom plooj piv rau cov duab meej thiab zoo ib yam uas lub plasma zaub muab. Ntxiv rau, daim duab ntawm "ntshav" tsis flicker thiab zoo li muaj tiag dua.
