Kodi ndi CRT polojekiti

Mwanjira padera ndi nthawi imene maalumali pafupifupi kwathunthu mbisoweka ma TV ndi oyang'anira zochokera luso cathode-ray. Kumbukirani, izi ndi zipangizo wolemera kuti zatenga pafupifupi theka la desiki kompyuta. Ndi tsopano makulidwe zambiri sathandiza kuposa 10 cm, ndiyeno yekha ndi nyali zounikira. N'zosadabwitsa zambiri amasangalala aiwala zimene CRT polojekiti. Koma sizinatheke! Ngakhale ngati kokha chifukwa chakuti ali patsogolo ngakhale Akhristu atsopano madzi-galasi zinthu zina.

Kodi CRT oyang'anira

Choyamba, tiyeni chinawathandiza kumvetsa n'chakuti achidule. Choncho, mawu akuti "CRT" amatanthauza elekitironi mtengo kapena, ngati ife tanenera kale, ndi cathode chubu (ku England CRT -. Cathode Ray-chubu). Kawirikawiri, pamene mawu akuti "chubu" anthu ambiri yamphamvu, malekezero a omwe palibe khoma. Kusiyapo mfundo zimenezi CRT polojekiti, m'pofunika kutchula kuti mu nkhani zimenezi chifaniziro ndi zabodza. Chifukwa mawonekedwe a chubu ali kutali ndege cylindrical ndipo amawachitira mbali imodzi. pamwamba chikuimira gawo la galasi kutsogolo, mmodzi ku zifaniziro anapanga. The mbali mkati mwa gawo ili TACHIMATA ndi chuma chapadera - phosphor. Mbali yake yapadera kuti ngati akulowa mtsinje wa particles mlandu pa izo awo mphamvu kayendedwe mwachibadwa ndi n'kukhala kuwala. Choncho, CRT polojekiti ndi chipangizo chimene matabwa a elekitironi ndi mitanda mkati mwa chophimba silhouetted chithunzi. Munthu amaona izo, chifukwa cha umuna wa phosphor lapansi.

Komano botololo aikidwa chipika wa maelekitirodi, wotchedwa Cannon. Kulenga mtsinje wa particles.

Mu mawu ena, CRT polojekiti imakhala ndi galasi chubu mfuti maelekitirodi ndi dera ulamuliro.

Mfundo ntchito

Monga amadziwika, kusakaniza chiŵerengero ena atatu mitundu zikuluzikulu: wobiriwira, wofiira ndi buluu - mukhoza kupeza ena onse, kuphatikizapo mithunzi. oyang'anira mtundu wonse wa mumtima pamwamba pa nsalu yotchinga ndizo pixels, conventionally m'magulu triads (midadada 3 zidutswa). Aliyense akhoza pounikira wa mitundu choyambirira. Ndipo maelekitirodi atatu, aliyense limene limafotokoza awo akuti "yekha". Mu ena kuti kuunikira ndi kudutsa iwo pa zenera, n'zotheka kupanga mtundu chifaniziro. Zodabwitsa ndizakuti, chipangizo mu utoto mfuti imodzi yokha.

Kulamulira otaya particles ntchito kuchimwa mu atomu ndi malangizo koyamba zoyenda analengedwa, chifukwa kusiyana ndi kuthekera.

Popeza mwaukadaulo kovuta kukwaniritsa ntchito yapadera olondola kusankha mtengo kugwa pa mfundo yake - chigoba. Ndi kulankhula, izi ndi gululi perforated pakati pa nsalu yotchinga ndi mfuti. Pali mitundu yosiyanasiyana ya masks. Mwina ali ndi udindo makhalidwe kuwonetsera (momveka, mawonekedwe-mapikiselo mfundo).

Popeza pambuyo kumenya chowala phosphor particles amachepetsa mofulumira kwambiri, muyenera zonse yolenganso fano. Onse malo amodzi ndi zazikulu. Choncho cheza jambulani mwatsatanetsatane ambiri chifaniziro cha nthawi pa mphindi. Izi wotchuka hedzi chimango chindodo. Pafupipafupi apamwamba, lisamaonekere kukulowa.

Panopa kukonza CRTs ntchito ina mu dongosolo kompyuta Sikoyenera, monga masiku LCD luso kwambiri zingamuthandize. Kupatulapo - ntchito yeniyeni.
