Muab piv nrog CRT cov saib, LCD overcomes cov shortcomings ntawm CRT loj loj, kev siv hluav taws xob thiab flicker, tab sis nws kuj coj teeb meem xws li nqi siab, dav saib kaum sab xis thiab tsis zoo xim xim. Txawm li cas los xij, technically, cov txiaj ntsig ntawm cov khoom siv lead ua kua tseem pom tseeb, thiab cov nram qab no muaj ntau yam tshwm sim:
1. Tsawg me me thiab nyhav dua
Cov lus CRT yuav tsum muaj cov duab thaij duab vim muaj cov duab tho tshuab siv, thiab siv hlua hluav taws xob hauv qhov kawg kom ntev tshaj 30 cm. Qhov loj ntawm tag nrho cov zaub yog ntawm chav kawm loj dua. Cov kua siv lead ua kua siv cov khoom siv lead ua kua, thiab tom qab ntawd siv cov kev sib piv coj los ua kom pom cov hom phiaj. Nws tsis tas yuav nruab ib cov duab raj hauv duab, thiab qhov ntim yog tau me me. Zoo li lub EMC 15-inch kua siv lead ua BM-568, nws lub ntim tsuas yog 19 nti CRT zaub ntim. Los ntawm ib nrab mus rau ib feem peb, nws muaj ib lub pob zeb loj thaum muab tso rau, thiab nws txoj kev loj me me yeej txo nws qhov hnyav.
2. Nres thaj tsam thaj tsam ze dua
Traditional CRT tus saib xyuas yog txwv los ntawm kev siv tshuab, thiab lawv loj me me tshaj qhov ntawm qhov screen. Feem ntau, 15-nti CRT saib, txawm tias nws loj npaum li cas yog 15 ntiv (inches), nws qhov muag pom tseeb Nws tsuas yog 14.1 nti xwb, thaum muaj 17-inch zaub tsuas muaj thaj tsam li ntawm 15 mus rau 16 ntiv hauv qab. Txawm li cas los xij, vim qhov sib txawv hauv cov qauv ntawm daim duab, qhov loj ntawm cov kua siv lead ua kua yog qhov pom ntawm cheeb tsam. Piv txwv, thaj chaw ntawm Samsung lub 15-nti LCD saib yog 15 inches tag, uas yog sib npaug ntawm cov duab ntawm ib tug 17-nti CRT saib. Thaj tsam, yog hais tias tus nqi ntawm ob yog zoo sib xws, ntawm chav kawm, nws yog ntau npaum li cas-zoo los yuav ib cov kua siv lead ua kua.
3. Zero hluav taws xob, tsis muaj ntiv tes
Lub CRT siv cov cathode cathode tube kuaj, thiab cov nplaim hluav taws xob muaj nyob rau hauv cov generates hluav taws xob ntau thiab hluav taws xob thaum tsiv, thiab ceev cov kab hluav taws xob hauv tshuab electronics, ntau dua qhov hluav taws xob, siv lub cev ntev puas rau lub qhov muag thiab tawv nqaij. Ua rau lub qhov muag myopia, tawv nqaij khaus thiab lwm yam teeb meem. Txij li cov kua siv lead ua kua siv cov kua siv lead ua kua, nws tsis yog qhov tsim nyog siv ib txoj hlua hluav taws xob hauv lub sijhawm ua haujlwm, yog li tsis muaj teeb meem uas lub zog hluav taws xob thiab hluav taws xob ua rau pom kev. Tsis tas li ntawd, qhov tsim ntawm daim duab ntawm CRT zaub yog ua los ntawm kab rov tav. Tsuas yog thaum lub sij hawm thaij tuaj yeem ncav cuag ib qho nqi, tsis muaj teeb meem tshwm sim, thiab cov khoom siv ua kua dej tsis tas yuav tsum muaj kev xa tshuaj, thiab ib daim duab yuav luag ib txhij ua, txawm yog qhov rov ua dua tshiab thiab tsis muaj qhov tsis muaj zog.
4. Tsawg zog siv zog thiab muaj zog tiv thaiv kev cuam tshuam
Ntxiv nrog rau Circuit Court thiab duab fais fab siv, CRT qhia txog lub hwj huam ntawm cov zaub. Cov kua siv lead ua kua yog siv rau kev teeb pom kev pom thiab kev siv hluav taws xob. Lub hwj huam tau siv ntawm cov zaub yog negligible, xws li EMC tus 15-nti display BM- Lub 568, uas siv tsuas yog 35 watts, ze li 50% me dua cov khoom CRT nrog tib qhov chaw pom. Tsis tas li ntawd, txij li cov kua siv ua kua dej tsis siv cov duab raj thiab rab phom electron rau duab zoo ib yam li cov CRT zaub, nws tsis tas yuav xav txog cov hluav taws xob loj tshwm sim los ntawm hluav taws xob nqaj hlau tawm ntawm rab phom electron, tab sis tsuas yog lub teeb tawm los ntawm lub raj tshuaj fluorescent kom tau lub ci ci, thiaj li hais tias nws muaj zog tsis kam. Kev muaj peev xwm cuam tshuam, txawm nyob hauv ib cheeb tsam kuj tseem ceeb, yuav yog ib qho zoo.
5. Cov duab zoo tshaj
Cov tshuaj CRT pom tau siv cov qauv analog tso tawm, thiab lub teeb liab ntawm lub npov tso saib pom tus analog cov zis, uas yuav ua rau cov duab yuav poob thaum lub sijhawm kev sib kis, ua rau lub degradation ntawm cov duab zoo, thiab lub teeb liab kis ntawm cov kua siv lead ua kua qhwv pom cov qauv. Cov tswv yim ncaj nraim ntawm cov pib ntsig txog qhov tsis paub los ntawm daim card ntaus ntawv yuav tsis ua teeb liab. Txawm li cas los xij, LCD monitors feem ntau tseem siv VGA interfaces rau cov lus qhia analog. Tsuas yog ib ob peb tuam txhab lag luam xws li EMC, Samsung, thiab ACER tau teeb tsa cov teeb meem digital video interfaces.
6. Siv ntau lub luag haujlwm
Vim cov khoom sib txawv thiab cov technologies siv hauv cov khoom siv lead ua kua, qee yam ntawm nws cov tsis muaj kev ruaj ntseg, uas yuav tsum tau kho qhov kev ntsuas ntawm cov khoom kom txawj ntse. Nyob rau hauv no hwm, txhua tus neeg tsim khoom muaj nws tus kheej mature technology. Feem ntau, Muaj ob hom loj. Ib tug yog zoo li EMC Pib-pib tsis siv neeg thiab kev pom kev ua haujlwm. Tsuas yog ib qho ntawm qhov tsis hloov kho, lwm cov kev tsis hloov kho rau qhov tseem ceeb coj los siv, thiab qhov kev pom zoo yog qhov tseeb. Cov nyhuv zoo. Lwm hom siv cov kev ua haujlwm ib qho rov qab, uas ua ntej yuav tsim ib qhov tseem ceeb, thiab txhua yam tsis tuaj yeem hloov rov qab rau lub Hoobkas kev tso cai nrog ib zaug xwb.
