Kev lag luam xav tau thiab kev txawj ntse ntawm LCD kua siv lead ua kua
Zaub yog ib qho tseem ceeb nruab nrab ntawm tib neeg thiab cov cav tov. Thaum ntxov CRT / Cathode Txoj Kev Taws Teeb (Tube) yog qhov tseem ceeb. Txawm li cas los xij, nrog kev sib tw hauv tshuab, ntau yam yees duab tau nce. Tsis ntev los no, LCD monitors tau ua nyias thiab teeb. , tsis tshua muaj hluav taws xob, tsis muaj hluav taws xob, tsis muaj teeb meem hluav taws xob, thiab muaj kev ruaj ntseg duab tsis muaj teeb meem, thiab lwm yam., nyob rau xyoo tsis ntev los no, tus nqi poob nqis los ntawm kev hloov maj mam hloov ntawm CRT qhov chaw khiav dej num, lub monitor yog tag nrho cov hnub qub. Yog li cas cov yeeb yam tshiab ntawm cov kua siv lead ua piv rau cov lus qhia?
Cov zaub mov zoo
Txij li txhua kis ntawm cov kua siv lead ua kua dej ua kom qhov xim thiab ci ntsa iab tom qab tau txais lub teeb liab, nws tuaj yeem lub teeb tsis tu ncua, tsis zoo li lub cathode txoj kab hluavtaws tso tawm (CRT), uas yuav tsum tau ua kom tsis tu ncua lub chaw ci ntsa iab. Vim li no, cov kua siv lead ua kua muaj cov duab zoo thiab tsis yoov, tsis yoj muag qhov muag qaug zog.
Tsis muaj hluav taws xob electromagnetic
Cov khoom siv ntawm cov lus qhia yog ib lub phosphor, uas yog tso tawm kom pom los ntawm cov nqaj hlau electron nqus ntawm lub phosphor. Cov nplaim hluav taws xob ua rau cov hluav taws xob tshuab hluav taws xob muaj zog nyob hauv lub caij nyoog uas nws ua rau lub phosphor, txawm tias muaj ntau cov khoom uas muaj tam sim no piv nrog kev tawg. Txoj kev kho kom zoo pab txo tau hluav taws xob ntau li ntau tau, tab sis nws tsis yooj yim kiag li. Hauv kev sib piv, cov kua siv lead ua kua muaj txiaj ntsim zoo hauv kev tiv thaiv kom tawg vim nws tsis muaj hluav taws xob txhua. Nyob rau hauv lub nam ntawm electromagnetic wave kev tiv thaiv, lub kua siv lead ua kua kuj muaj nws tus kheej zoo. Nws txais ib txoj kev siv tshuab sealing nruj heev thiab ib qho tsawg tsawg ntawm electromagnetic tsis muaj nyob rau hauv cov lus. Txhawm rau dissipate lub tshav kub, cov zaub zoo tib yam yuav tsum ua kom muaj kev sib tiv tauj nrog cov huab cua kom ntau li ntau tau. Lub electromagnetic tsis tau tsim los ntawm cov khoom siv sab hauv tseem xaim "tawm sab nraud" nyob rau hauv loj qhov ntau.
Loj saib loj
Rau tib qho loj, cov kua siv lead ua kua muaj thaj tsam loj dua. Kev saib cheeb tsam ntawm cov kua siv lead ua kua yog tib yam li nws cov kab pheeb ces kaum. Lub cathode txoj kab hluav taws xob tso tawm muaj ib nti los yog ib qho puag ncig ntawm sab xub ntiag ntawm lub raj xa duab thiab tsis tuaj yeem siv rau cov khoom.
Daim duab zoo
Sib piv nrog cov tshuaj pom, cov kua siv lead ua kua siv lub phaj purely lub iav thaum pib, thiab nws cov nyhuv tso tawm yog lub kaum sab xis ntawm lub dav hlau, muab cov neeg ua zoo rau nws. Thiab cov kua siv lead ua kua yog qhov yooj yim ua kom muaj kev sib haum xeeb rau ib cheeb tsam me me ntawm qhov screen. Piv txwv li, 17-inch kua Crystal teeb yuav ncav cov lus daws 1280 × 1024, thiab kev daws teeb meem ntawm 1280 × 1024 los yog ntau tshaj feem ntau yog siv rau ntawm 18-inch CRT xim xim. Cov duab nyhuv tsis txaus siab kiag li.
Tsawg zog noj
Cov zaub no yog tsim los ntawm ntau cov circuits. Thaum cov circuits tsav cathode txoj kab tshav dav hlau, lawv yuav tsum haus cov hwj huam ntau. Nrog rau qhov nce ntawm lub ntim, lub hwj huam siv los ntawm lub circuits sab hauv yeej yuav nce. Nyob rau hauv kev sib piv, lub hwj huam ntawm cov kua siv lead ua kua yog cov khoom noj hauv nws cov electrodes thiab kev tsav ICs, thiab yog li lub hwj huam noj ntau dua li ntawm cov pa zaub.
