Abaqaphi abadala basebenzisa i-tube ye-cathode ray ukubonisa imifanekiso
Isicatshulwa njenge-CRT, i-cathode ray tube ityhupu enkulu yokucoca isetyenziswe ukubonisa umfanekiso kwiskrini. Ngokuqhelekileyo, ibhekisela kuluhlu lwekhompyutheni esebenzisa i-CRT.
Nangona ukuboniswa kwe-CRT (ngokuqhelekileyo kuthiwa "i-tube" i-monitor) iyanqabile kwaye ithatha indawo eninzi yedesksi, ngokuqhelekileyo inokwakheka kwesikrini esincinci kunezobuchwepheshe ezintsha bokubonisa.
Isixhobo sokuqala se-CRT sabizwa ngokuba yi- Braun tube kwaye yakhiwe ngo-1897. Umboniso wokuqala we-CRT owenziwe kuluntu wawukho ngo-1950. Kwiminyaka emininzi ukususela ngaloo ndlela, amadivaysi amasha abone ukuphucula ubungakanani obukhulu kunye nobukhulu besikrini, kodwa kunye nokusetyenziswa kwamandla, iindleko zokuvelisa, ubunzima, nomfanekiso / umbala.
Ii-CRTs zigqityiweyo zatshintshwa ubuchwepheshe obutsha obanikezela ngolu phuculo olunzulu, njengeLCD , i- OLED kunye ne- Super AMOLED .
Qaphela: I- SecureCRT, umthengi weTelnet, ebizwa ngokuba yi-CRT kodwa ayinanto enxulumene nabagadi be-CRT.
Njani i-CRT Monitor Work
Kukho iintsimbi ezintathu ze-electron ngaphakathi kwenkqubo yokujonga i-CRT yanamhlanje esetyenziselwa umbala obomvu, obuluhlaza kunye nobomvu. Ukuvelisa umfanekiso, batyelela i-electron kwi-phosphor ukuya ekupheleni komboniso. Iqala kumgca ophezulu okhohlo kwesikrini uze uhambe ukusuka kwesobunxele ukuya kwesokudla, umgca omnye ngexesha, ukugcwalisa isikrini.
Xa i-phosphor ishaywa yi-elektroniki, ibenza bakwazi ukuvutha kwii-frequencies ezithile, ngokukodwa ngamaphikseli, ixesha elithile. Oku kudala umfanekiso ofunekayo usebenzisa umxube wemibala ebomvu, eluhlaza, kunye nohlaza.
Xa omnye umgca uveliswa kwisikrini, i-electron guns iyaqhubeka kunye, kwaye uqhubeke uyenza ukuze isikrini sonke sigcwaliswe ngomfanekiso ofanelekileyo. Ingcamango yenkqubo yokukhawuleza ngokwaneleyo ukuba uyabona umfanekiso omnye, nokuba isithunzi okanye ifreyimu enye kwividiyo
Ulwazi olungakumbi kwi-CRT Displays
Isilinganiselo sokuvuselela isikrini se-CRT sinquma ukuba isantya siza kusihlaziya iskrini ukwenzela ukuvelisa umfanekiso. Ngenxa yokuba i-phosphor ephazamisayo ayigcinwanga ngaphandle kokuba isikrini sihlaziyeke, isantya esincinane sokuvuselela isizathu sokuba ezinye i-CRT zikhangele amava atshabalalayo okanye aphumayo, imigca ehambayo.
Yintoni eyenzekayo kwezo meko i-monitor ilungisa ngokukhawuleza ukuba ubone ukuba yeyiphi inxalenye yeskrini engabonisi umfanekiso.
Abagadi be-CRT basengozini yokuphazamiseka kwe-electromagnetic ukususela ekubeni umbane uvumela ukuba iifowuni zihambele ngaphakathi kweso. Olu hlobo lokuphazamiseka alukho kwizikrini ezitsha ezifana nee-LCD.
Iphulo: Bona indlela yoDegauss kwi-Computer Monitor xa ufumana ukuphazamiseka kwamaginti kwinqanaba elithethiweyo .
Kwi-CRT enkulu kunye enzima ayikho kuphela i-electron emitters kodwa iphinda igxininise kwaye ifake iikhoyili. Yonke into eyenza i-CRT ihlolisise kakhulu, ke kutheni izikrini ezitsha ezisebenzisa ubuchwephesha obuhlukeneyo njenge-OLED, lunokuba luncinci.
Iphaneli yendiza ibonisa ukuba i-LCD ingenziwa ibe enkulu (ngaphezu kwama-60 ") ngelixa i-CRT ibonisa ngokubanzi malunga ne-40" ekugqibeleni.
Ezinye izixhobo zokusebenza ze-CRT
I-CRT nayo isetyenzisiwe kumadivayisi angabonakali, njengokugcina idatha. I-tube yaseWilliam, njengoko yayibizwa ngokuba yiyo, yayiyi-CRT eyayingagcina idatha yebinary.
Isandiso sefayile ye .CRT ngokucacileyo asihambelani nobugcisa bokubonisa, kwaye isetyenziselwa isakhiwo sefayile yeSitifiketi soKhuseleko. IiWebhsayithi zizisebenzise ukuqinisekisa ukuzisiza kwazo.
Kuyafana nelayibrari yeC runtime (CRT) enxulumene nolwimi lweC programming.
