Oyang'anitsitsa achikulire amagwiritsa ntchito chubu yotchedwa cathode ray kuti asonyeze zithunzi
Ophatikizidwa ngati CRT, chubu yotchedwa ray tube ndi chubu yaikulu yotukira yomwe imagwiritsidwa ntchito kusonyeza chithunzi pawindo. Kawirikawiri, imatanthawuza mtundu wa kompyuta kuyang'anira CRT.
Ngakhale ma CRT maulendo (omwe amatchedwa "tube" oyang'anitsitsa) alidi amphamvu ndipo amatenga malo ambirimbiri, nthawi zambiri amakhala ndi mawonekedwe ochepa kwambiri a mawonekedwe kusiyana ndi matebulo atsopano.
Chipangizo choyamba cha CRT chinatchedwa tube ya Braun ndipo inamangidwa mu 1897. TV yoyamba ya CRT yomwe inaperekedwa kwa anthu onse inali mu 1950. Kwa zaka zambiri kuyambira nthawi imeneyo, zipangizo zatsopano zakhala zikuwonetseratu kusintha kwa kukula kwake ndi kukula kwake, koma komanso kugwiritsa ntchito mphamvu, kupanga ndalama, kulemera, ndi fano / mtundu.
Nkhoti zatsimikiziridwa kuti zasinthidwa ndi matekinoloje atsopano omwe amapereka kusintha kwakukulu, monga LCD , OLED , ndi Super AMOLED .
Zindikirani: SecureCRT, wogula Telnet, ankatchedwa CRT koma alibe chochita ndi oyang'anira CRT.
Momwe Oyang'anira A CRT Amagwira Ntchito
Pali mfuti zitatu za electron mkati mwa mawonekedwe a CRT amakono omwe amagwiritsidwa ntchito kwa mtundu wofiira, wobiriwira, ndi wabuluu. Kuti apange fano, amawombera ma electron pa phosphor kutsogolo kutsogolo kwake. Zimayambira pamwamba kumanzere kumapeto kwa chinsalu ndikusunthira kuchoka kumanzere kupita kumanja, mzere umodzi pa nthawi, kudzaza chinsalu.
Phosphor ikagwedezeka ndi makompyutawa, imawathandiza kuwotcha maulendo, makamaka ma pixel, kwa nthawi yeniyeni. Izi zimapanga chithunzi chofunikira pogwiritsa ntchito mitundu yofiira, ya buluu, ndi yobiriwira.
Pamene mzere umodzi umapangidwa pawindo, mfuti za electron zipitiliza ndizotsatira, ndipo pitirizani kuchita izi mpaka pulogalamu yonseyo ili ndi chithunzi choyenera. Lingaliro ndilo kuti njira ifulumire mwangoona chithunzi chimodzi, kaya chithunzi kapena chimango chimodzi muvidiyo
Zambiri zowonjezera pa CRT
Pulojekiti ya CRT yowonetseratu zowonjezera imatsimikizira momwe khungu likutsitsimutsira chinsalu kuti chikhale chithunzi. Chifukwa chowotcha phosphor sichikhazikika pokhapokha ngati chinsalucho chikutsitsimutsidwa, kuchepa kwapafupi ndiko chifukwa chake oyang'anira ena a CRT ali ndi mizere yozungulira kapena yodutsa.
Zomwe zikukuchitikirani muzochitikazi ndizowunikira pakutsitsimula pang'onopang'ono kuti muwone kuti mbali zina zowonekera siziwonetsanso chithunzi.
Owonetsa CRT ali pangozi ya kusokonezeka kwa magetsi kuchokera pamene maginito ndi omwe amalola kuti magetsi azisunthira mkati. Kusokoneza kotereku sikukupezeka ndi zowonetsera zatsopano monga LCD.
Chizindikiro: Onani Mmene Mungagwiritsire Ntchito Degauss ndi Computer Monitor ngati mukukumana ndi maginito kuti masewerowa achoke .
Mu CRT yaikulu ndi yolemetsa sikuti ndi electron emitters koma amagwiritsa ntchito makompyuta. Zida zonsezi zimapangitsa CRT kuyang'anitsitsa kwambiri, chifukwa chake masewera atsopano omwe amagwiritsira ntchito matekinoloje osiyanasiyana monga OLED, akhoza kukhala ochepa kwambiri.
Pulogalamu yazitali ngati ma LCD angapangidwe kukhala aakulu (oposa 60 ") pomwe ma CRT mawonetsero amakhala pafupifupi 40" pamtunda.
Matumizi ena a CRT
CRT imagwiritsidwanso ntchito pazinthu zosasonyeza, monga kusunga deta. The tube tube, monga idatchulidwira, inali CRT yomwe ingasunge data ya binary.
Zowonjezera za fayilo ya .CRT sizigwirizana ndi makina owonetsera, ndipo m'malo mwake amagwiritsidwa ntchito popanga mafayilo a Security Certificate. Mawebusaiti amawagwiritsa ntchito kutsimikizira awo.
Chimodzimodzi ndi labukhu la C runtime (CRT) lomwe limagwirizanitsidwa ndi chinenero cha C.
