Technology yog tas li innovating, thiab tso saib technology yog nce sai heev. Cov kua siv lead ua kua (LCD) muaj cov txiaj ntsig zoo xws li qhov me me, lub teeb yuag, kev siv hluav taws xob tsawg, thiab nws cov duab ruaj khov thiab tsis flicker. Tus nqi kuj pheej yig heev. CRT saib tau maj mam hloov. Dab tsi yog cov yam ntxwv pom tseeb ntawm LCD piv nrog CRTs yav dhau los?
1. Cov zaub zoo yog siab
Txhua lub ntsiab lus ntawm lub vijtsam LCD tuav cov xim tom qab tau txais lub teeb liab, thaum lub cathode ray tube zaub (CRT yuav tsum tau ua kom lub teeb ci ntsa iab tas li. Yog li ntawd, cov duab zoo ntawm LCD zaub tsis yog siab xwb, tab sis kuj tsis Flicker, txo. qhov muag nkees.
2. Loj saib thaj tsam ntawm LCD npo
Nyob rau hauv cov ntaub ntawv ntawm tib qhov loj, LCD kua siv lead ua zaub tuaj yeem pom thaj tsam loj dua, qhov pom ntawm cov kua siv lead ua kua thiab cov kab pheeb ces kaum yog tib yam, tab sis cov zaub CRT kuj yog ib nti Tsis muaj txoj hauv kev los tso saib nws. ib txwm.
Peb, LCD muaj ntau yam kev siv
Thaum pib, lub vijtsam LCD tsis tuaj yeem pom cov cim, thiab feem ntau nws yog siv rau hauv lub tshuab hluav taws xob thiab lub tshuab xam zauv. Nrog rau kev txhim kho txuas ntxiv thiab kev nce qib ntawm cov kua siv lead ua kua siv thev naus laus zis, cov cim tuaj yeem pom, thiab cov xim yooj yim tshaj plaws kuj tau txais kev txhawb nqa, thiab maj mam siv rau LCD TVs, LCD saib ntawm camcorders, handheld game consoles, thiab lwm yam.
Tom qab ntawd, DSTN thiab TFT tau dav ua raws li cov khoom siv LCD hauv computers. DSTN LCD cov ntxaij vab tshaus tau siv hauv cov khoos phis tawj thaum ntxov. TFT LCD cov ntxaij vab tshaus tau siv nyob rau hauv phau ntawv computers (feem ntau phau ntawv computers yog tam sim no Siv TFT zaub screen), thiab siv nyob rau hauv lub ntsiab desktop zaub.
Plaub, cov nyhuv ntawm daim duab yog qhov zoo
Piv nrog rau cov khoom siv ib txwm siv, cov kua siv lead ua kua siv lub iav phaj, cov nyhuv cov duab zoo dua, thiab nws qhov kev daws teeb meem kuj yog siab heev.
Tsib, digital interface
Cov kua siv lead ua kua feem ntau yog cov digital, thiab cathode ray tube xim qhia siv analog interfaces. Thaum siv cov kua siv lead ua kua, daim npav duab tsis tas yuav tsum tau hloov dua siab tshiab. Nyob rau hauv txoj kev xav, qhov no yuav ua rau cov xim thiab qhov chaw zoo dua thiab zoo meej.
Rau, lub" lub cev" yog qhov zoo-proportioned thiab compact
Cov zaub ntawm ib txwm cathode ray tube muaj lub raj xa hluav taws xob tom qab nws. LCD saib tsis muaj nws, yog li nws yuav ua rau tib neeg muaj kev xav tshiab. Cov khoom siv ib txwm siv phom hluav taws xob los tawm cov kab hluav taws xob thiab xa mus rau qhov screen. Qhov no yog kev txwv heev. Lub raj txoj kab uas hla ntawm daim duab raj tsis tuaj yeem luv luv, uas ua rau qhov loj ntawm cov duab loj dua.
Cov kua siv lead ua kua yog pom tau los ntawm kev hloov lub xeev ntawm cov kua siv lead ua kua molecules los ntawm cov electrodes ntawm qhov screen. Txawm hais tias qhov screen loj, nws qhov ntim yuav tsis nce proportionally, thiab qhov hnyav yuav sib dua.
Xya, lub zog siv me me
Lub voj voog sab hauv ntawm cov khoom siv ib txwm muaj qhov nyuaj heev, thiab cov duab hluav taws xob cathode yuav tsum tau siv ntau lub zog los ua haujlwm. Raws li nws qhov ntim tau nce, lub zog siv los ntawm kev siv hluav taws xob sab hauv kuj tseem yuav nce ntxiv. Nyob rau hauv sib piv, lub hwj chim noj ntawm ib tug kua siv lead ua kua zaub yog tsuas yog noj ntawm nws sab hauv electrodes thiab tsav IC, yog li ntawd lub hwj chim noj yuav tsawg dua li ntawm ib txwm zaub.
