Cov neeg saib xyuas qub siv lub cathode txoj kab tshav dav hlau los tso saib cov duab
Nkag li CRT, cathode txoj kab hluav taws xob yog lub tshuab nqus tsev nqus siv los tso khoom rau ntawm ib qho screen. Feem ntau, nws yog hais txog hom computer saib xyuas siv CRT.
Txawm hais tias CRT qhia (feem ntau hu ua "tube" saib) yog cov khoom loj heev thiab coj mus ntau qhov chaw, lawv feem ntau muaj ntau me me npo me tshaj li cov duab tshiab.
Tus thawj thawj CRT ntaus ntawv hu ua Braun tube thiab nws tau tsim ua xyoo 1897. Tus thawj CRT TV tau muaj rau cov pej xeem nyob hauv xyoo 1950. Ntau xyoo dhau los lawm, cov cuab yeej tshiab tau pom kev txhim kho tsis tau tsuas yog tag nrho qhov loj thiab ntsuas qhov dav, tab sis kuj siv hluav taws xob, tsim nqi, hnyav, thiab duab / xim.
CRTs tau kawg hloov los ntawm cov cuab yeej tshiab uas muaj cov kev txhim kho zoo li no, xws li LCD , OLED , thiab Super AMOLED .
Lus Cim: SecureCRT, ib tus neeg siv Telnet, siv hu ua CRT, tiam sis nws tsis muaj dab tsi ua nrog CRT tus saib xyuas.
Cas CRT Saib Xyuas Haujlwm
Muaj peb hom hlau phom nyob hauv CRT tus qauv tshiab uas siv rau xim liab, ntsuab, thiab xiav xim. Yuav tsim ib cov duab, lawv tua electrons ntawm phosphor mus rau sab pem hauv ntej ntawm lub monitor. Nws pib rau sab laug ntawm ntug qhov screen thiab ces txav ntawm sab laug mus rau sab xis, ib kab ntawm ib lub sij hawm, los ua qhov screen.
Thaum phosphor raug ntaus nrog cov khoom siv hluav taws xob no, nws ua rau lawv ci rau cov zaus nrawm, tshwj xeeb yog pixels, rau ib qho kev siv sij hawm ntev npaum li cas. Qhov no tsim cov duab uas yuav tsum tau siv los ntawm cov xim liab, xiav, thiab xim ntsuab.
Thaum twg ib txoj kab ntawm lub vijtsam, cov phom tua hluavtaws txuas ntxiv nrog rau lwm zaus, thiab ua qhov no kom txog thaum tag nrho cov vijtsam uas muaj cov duab zoo. Lub tswv yim yog rau txoj kev ua kom yooj yim txaus tias koj tsuas yog pom ib tus duab, seb nws yog ib daim duab los sis ib qho duab hauv ib daim duab

Ib qho CRT qhov kev hloov tshiab tus nqi pom tau tias feem ntau npaum li cas tus saib xyuas yuav ua rau qhov kev ntsuas kom tsim tau cov duab. Vim tias cov phomphor glowing effect no tsis muaj kev cuam tshuam tshwj tsis yog tias lub screen yog refreshed, ib qhov qis dua tshiab yog vim li cas qee cov CRT saib cov kev ua kom muaj kev tawm los yog tawm ntawm chaw, tsiv kab.
Dab tsi yog tau ntsib nyob rau hauv cov xwm txheej yog qhov kev txhawb zog qeeb txaus uas koj tuaj yeem pom uas feem ntawm qhov screen tsis tau qhia cov duab.
CRT tus saib xyuas yuav raug qhov kev pheej hmoo rau electromagnetic cuam tshuam txij thaum lub hlau nplaum yog dab tsi pub rau cov electrons txav hauv lub tshuab. Hom kev cuam tshuam no tsis muaj nyob nrog cov duab tshiab xws li LCDs.
Ntsis: Saib Yuav ua li cas Degauss Saib Xyuas Computer yog tias koj tab tom muaj teeb meem sib sib zog nqus cuam tshuam rau qhov point uas qhov khoos phis tawm .
Nyob rau hauv lub loj thiab hnyav CRT tsis tsuas electron emitters tab sis kuj tseem ceeb thiab deflection coils. Tag nrho cov apparatus yog dab tsi ua rau CRT tsom kwm loj, uas yog vim li cas cov tshiab cov ntxaij vab tshaus uas siv ntau yam yees duab zoo li OLED, yuav yog li nyias.
Vaj huam sib luag qhia cov lus zoo li LCDs tuaj yeem ua kom loj tiag tiag (tshaj 60 ") thaum CRT cov lus qhia feem ntau yog nyob ntawm 40" ntawm qhov siab tshaj plaws.
Lwm yam CRT siv
CRT kuj tau siv rau cov khoom tsis-tso, zoo li khaws cov ntaub ntawv. Williams raj, raws li nws tau hu, yog CRT uas yuav khaws cov ntaub ntawv binary.
Lub .CRT cov ntaub ntawv txuas ntxiv yog tsis ncaj nraim rau kev siv tshuab, thiab nws tsis yog siv rau Daim Ntawv Pov Thawj Zeem cov ntaub ntawv. Cov websites siv lawv los kuaj xyuas lawv tus kheej.
Zoo ib yam li C Lo (CRT) cov tsev qiv ntawv cuam tshuam nrog hom lus C programming.
