CRT-monitor: tsanangudzo, zvikamu zvekutanga zvechigadzirwa

Mucherechedzo weCRT chigadziro chinobva pa cathode-ray tube. Iyi teknolojia yakagadzirwa kumashure muna 1897 neasayendisiti weGermany F. Brown. Pakutanga, yakasikwa senhumbi yakagadzirirwa yakagadzirirwa kuenzanisa kushandura ikozvino (an oslosloscope).

CRT-monitor uye yakagadzirwa

Chinhu chikuru chechigadzirwa chakadaro kinescope. Inosanganisira girazi remvura inotapira, iyo mweya inobviswa (kureva, chivharo mukati maro). Imwe mugumo we tube ndiyo yakadzika uye yakafara - iyi skrini, uye imwe - yakareba uye yakamanikana - ndiyo mitsipa. Rutivi rwomukati rwebhuku kubva mukati runofukidzwa nehuwandu hwephosphor (yakabva yttrium uye erbium). Chimwe chinhu chinotevera cheCRT chekuongorora ndeyepfuti ye electron, iyo iyo magetsi inotenderera inotangira pasi pekuita kwemaunda emagetsi , kuitira kuti chifananidzo chionekwe pahwindo. Elementary particles inopfuura nepakati pemataresi esimbi uye inowira kurutivi rwomukati rwegirazi regirazi, rakafukidzwa nemaposphor mavara emarudzi akasiyana. Nzira yakasarudzwa yekudzivirira inochengetedza kubatana kwakasimba kunowanikwa pane screen screen. Kusiyanisa zvirongwa ndezvipi zvemarudzi maviri: chikafu uye toroidal. Izvo sangano rinosanganisira inductors yakaiswa mumuromo we kininescope.

Chinhu chinotevera chinotsanangura kuongorora kweCRT ndiyo fomu uye nhamba yekutsvaga unit. Iyi node ndiyo inokonzera kupindira mubasa rekufambisa. Simba rinoshandiswa nodesiti idzi ndechimwe chezvinhu zvikuru zvinotarisirwa pakugadzira kuongorora kwe CRT. Chimwe chinotevera chekugadzirwa ndiko kukwirira kwema modulator, iyo, pamwe nekufambisa kwehutano, inoshanda pamutemo wezvingave zvakasiyana. Nokuda kwemasero aya, magetsi anoshandisa simba, chikamu chacho chinopedzerwa ne luminescence ye phosphor.

RGB teknolojia

Kazhinji ruvara rweCRT rinoshandisa mabhandi matatu emagetsi, uye monochrome imwe. Izvi zvinowirirana nemamwe mavara makuru: tema, tsvuku uye bhuruu. Kushamwaridzana kwavo kunokwanisa kugadzira nhamba dzisingagumi dzemumvuri uye mavara. Kudzora cathode ray-tubes inoda kudzora magetsi, iyo inosarudza kunaka kwekuongorora. Ndiyo musiyano muhutano hwemagetsi hwakagadzirwa nevakagadziri vakasiyana-siyana, ndiyo mamiriro ekugadzirisa musiyano pakati pe CRT-vatariri, pasinei nokuti iyo cathode-ray ray mukati mavo yakafanana. Saka, imwe yepfuti inodhonza kubuda kunokanganisa phosphor mapepa emarudzi akasiyana-siyana. Chigadzirwa chemagetsi chemavara akafanana chinofanira kungogadzirisa zvinhu zvehuvara. Kuti uite chiito ichi chakaita sechishandiswa, shandisa masikisi chaiwo, chimiro chacho chinoenderana nerudzi rwekinescope.

Kugadziriswa kweRT-vatariri

Izvo zvinokonzera kushandiswa kwezvikwata zveRTT iko kukanganisa kwesimba rekubatsira kwekuita. Kazhinji kazhinji izvi zvinokonzerwa nekuchinja kwemagetsi mumagetsi. Kana simba racho risina kukwana, saka kuparara kweimwe mamwe ma modules, somuenzaniso, ruvara runopesana nokuputsika, kupesana kwechifananidzo, kunoitikawo. Mukuwedzera kune simba rinoputika, zvikonzero zvekukundikana kwevatariri zvinowanzowanzoita zvinokanganisa (zvinogadzirisa), kutarisa kune zvitubu zvemagetsi emagetsi, guruva rekuongorora, kupisa, kukwegura kwezvinhu. Kuita zvechisimba kwehurumende yekutonhorera kunogona kutungamirira kukundikana kwekugadzira bhidhiyo yemavhidhiyo uye zvirongwa zvekugadzira. Kurwisana kwebasa rekutsvaga kwakakwana kunokonzerwa nokuputsika kwepamusoro-voltage circuits uye TDKS. Chimwe chezvikonzero zvechiitiko ichi ndicho guruva.
