Lub LCD yog ib lub tiaj thiab ultra-nyias zaub ntaus ntawv, uas yog tsim los ntawm ib tug tej yam xim los yog dub thiab dawb pixels, muab tso rau pem hauv ntej ntawm lub teeb los yog xav txog. Cov kua siv lead ua kua muaj kev siv hluav taws xob tsawg heev, yog li lawv tau nyiam los ntawm cov kws tsim khoom thiab tsim nyog rau cov khoom siv hluav taws xob uas siv roj teeb. Nws lub hauv paus ntsiab lus tseem ceeb yog los txhawb cov kua siv lead ua kua molecules los tsim cov dots, kab, thiab qhov chaw nrog lub teeb rov qab raj los tsim ib daim duab. Yog li dab tsi yog qhov zoo ntawm cov ntxaij vab tshaus LCD? Tus editor ntawm Zhilingxin yuav qhia rau koj.
Technical zoo ntawm cov ntxaij vab tshaus LCD:
1. Qhov loj me thiab qhov hnyav dua
Cov tsoos CRT saib siv cov duab tube thev naus laus zis los ua duab, nws yuav tsum muaj lub tshuab nqus tsev duab, thiab tom qab ntawd nruab nrog rab phom electron thaum kawg, kom qhov ntev yog feem ntau ntau dua 30 cm, yog li qhov ntim ntawm tag nrho cov zaub yog ntawm chav kawm loj. Cov kua siv lead ua kua siv cov khoom siv ua kua siv lead ua kua, thiab tom qab ntawd siv cov cuab yeej siv tshuaj ntsuam xyuas kom ua tiav cov hom phiaj pom. Tsis tas yuav tsum tau nruab ib lub raj duab hauv cov zaub, thiab qhov ntim yog qhov me me.
2, qhov txheeb ze zaub cheeb tsam loj dua
Vim qhov kev txwv ntawm kev siv thev naus laus zis, cov tshuaj CRT tsoos qhia tias qhov loj me dua li qhov chaw ntawm lub vijtsam fluorescent. Feem ntau, ib qho 15-inch CRT saib muaj qhov loj ntawm 15 ntiv tes, tab sis nws qhov pom tseeb tiag Nws yuav tsuas yog kwv yees li 14.1 ntiv tes xwb, thiab 17-inch zaub yuav tsuas muaj 15 mus rau 16 ntiv ntawm thaj chaw tso saib. sab laug. Txawm li cas los xij, vim yog cov qauv duab sib txawv ntawm cov kua siv lead ua kua, qhov loj qhia tau yog qhov chaw tso saib tiag tiag. Piv txwv li, thaj chaw tso saib ntawm Samsung's 15-inch LCD yog ua tiav 15-inch, uas yog sib npaug rau thaj tsam ntawm 17-inch CRT saib. , Yog hais tias tus nqi ntawm ob yog zoo sib xws, ntawm chav kawm nws yog ntau npaum li cas nqi-zoo mus yuav ib tug LCD saib.

3, xoom hluav taws xob, tsis muaj flicker
CRT saib siv cov duab cathode rau kev thaij duab. Cov kab hluav taws xob muaj nyob rau hauv nws tsim hluav taws xob zoo li qub thiab hluav taws xob ntau thaum ua haujlwm. Qhov ceev ntawm lub teeb hluav taws xob ceev, qhov hluav taws xob ntau dua. Kev siv tib neeg lub cev mus ntev yuav ua rau lub qhov muag thiab tawv nqaij puas. Ua rau myopia, tawv nqaij ua xua thiab lwm yam teeb meem. Txij li cov kua siv lead ua kua siv cov khoom siv ua kua siv lead ua kua, tsis tas yuav siv cov kab hluav taws xob thaum ua haujlwm, yog li tsis muaj hluav taws xob zoo li qub thiab hluav taws xob cuam tshuam rau kev pom. Tsis tas li ntawd, ib daim duab ntawm CRT zaub yog tsim los ntawm kev luam theej duab. Tsuas yog thaum lub scanning zaus nce mus txog ib qho nqi, tsis muaj flicker. Txawm li cas los xij, cov kua siv lead ua kua tsis xav tau cov txheej txheem scanning. Ib daim duab tsim yuav luag tib lub sijhawm, txawm tias qhov hloov tshiab zaus Nws tsawg heev thiab yuav tsis muaj flicker txhua.
4, tsawg zog noj, muaj zog tiv thaiv kev cuam tshuam muaj peev xwm
Ntxiv nrog rau kev siv lub zog ntawm lub voj voog thiab cov duab tube, CRT zaub kuj muaj lub zog noj ntawm lub vijtsam zaub, thiab cov kua siv lead ua kua zaub yog qhov tseem ceeb ntawm kev siv hluav taws xob ntawm lub teeb nraub qaum thiab lub voj voog, thiab kev siv hluav taws xob ntawm cov khoom siv hluav taws xob. zaub screen tuaj yeem tsis quav ntsej. Tsis tas li ntawd, vim tias cov kua siv lead ua kua tsis siv lub raj duab thiab cov phom hluav taws xob zoo li CRT cov zaub, nws tsis tas yuav xav txog cov hluav taws xob hluav taws xob siab uas tshwm sim los ntawm kev nce cov hluav taws xob hluav taws xob los ntawm cov phom hluav taws xob, tab sis tsuas yog tau txais qhov ci ntsa iab. los ntawm lub teeb rov qab tawm los ntawm lub raj fluorescent, yog li nws muaj zog tiv thaiv. Kev cuam tshuam muaj peev xwm, txawm tias nyob hauv ib puag ncig nrog lub teeb pom kev zoo, koj yuav tau txais cov txiaj ntsig zoo.
5, daim duab zoo dua
Cov tsoos CRT saib feem ntau txais yuav analog zaub hom, thiab cov teeb liab tso zis ntawm cov khoom siv analog tso zis hom, uas yuav ua rau cov duab poob thaum lub sij hawm kis tau tus mob, uas ua rau ib tug poob rau hauv daim duab zoo, thaum lub teeb liab kis tau tus mob ntawm cov kua siv lead ua zaub txais cov hom digital. , uas yog ncaj qha los ntawm daim card graphics. Kev tso tawm cov teeb liab yuav tsis ua rau lub teeb liab poob, tab sis feem ntau cov duab LCD tseem siv VGA interfaces rau cov lus qhia analog, thiab tsuas yog ob peb lub tuam txhab tau teeb tsa cov teeb liab video interfaces.
6, kev siv lub luag haujlwm yog qhov ntse dua
Vim hais tias ntawm cov khoom sib txawv thiab cov thev naus laus zis siv hauv cov kua siv lead ua kua, qee qhov ntawm nws qhov tsis muaj feem ntau yog kho, uas yuav tsum tau ua haujlwm ntawm cov zaub kom raug kho kom ntse dua. Hauv qhov no, txhua tus neeg tsim khoom muaj nws tus kheej cov cuab yeej paub tab.
7. Ib qho kev dhia hauv cov khoom siv
Cov tsoos CRT saib siv lub iav ultra-thick zaub. Txawm hais tias sab nrauv yog tiaj tus zoo li cov kua siv lead ua kua, lub puab nto yog me ntsis nkhaus, uas zoo li concave, thiab cov duab yuav txawv me ntsis. Cov khoom siv yooj yim siv hauv cov kua siv lead ua kua yog cov kua siv lead ua kua-ib yam khoom uas muaj ob qho tib si fluidity ntawm cov kua thiab cov txheej txheem tsis tu ncua ntawm cov muaju. Thaum cov kua siv lead ua kua yog rhuab mus rau ib qho twg, nws yuav dhau los ua kua pob tshab. Tom qab txias, nws yuav qhia cov yam ntxwv ntawm cov muaju. Vim hais tias cov yam ntxwv ntawm cov kua siv lead ua kua yog nruab nrab ntawm cov khoom thiab cov kua, nws tsis tsuas yog muaj cov yam ntxwv kho qhov muag ntawm cov khoom siv lead ua, tab sis kuj muaj cov yam ntxwv ntws ntawm cov kua. Cov kua siv lead ua kua siv cov yam ntxwv no kom ua tiav lub hom phiaj ntawm kev kos duab.
