Vakuru vevatariri vanoshandisa cathode ray ray kuti varatidze mifananidzo
Yakapfupiswa seCRT, cathode ray tube ipurasitiki huru inoshandiswa kuratidza mufananidzo pachigadziko. Kazhinji, rinoreva rudzi rwekombiyuta kutarisa kushandisa CRT.
Kunyange zvazvo kuratidzwa kweCRT (kazhinji kunonzi "tube" vatariri) ndeyechokwadi uye inotora nzvimbo yakawanda yedeskiti, ivo kazhinji vane uwandu hwemahwindo kadiki pane hutaneti hutsva hwekuratidzira.
Imwe yekutanga CRT device yainzi Braun tube uye yakavakwa muna 1897. Yokutanga yeTV yakapihwa yakawanikwa kuvanhu vose yaiva muna 1950. Kwemakore mazhinji kubvira ipapo, madivashoni matsva akaona kuvandudzwa kwete kwete chete ukuru hwemazana uye chiyero chepiritsi, asi uyewo mumashandisirwo emagetsi, kushandiswa kwezvinhu, uremu, uye mufananidzo / ruvara.
Vatongi vekupedzisira vakatsiviwa nehutachiona hutsva hunoita kuti hurumende idzi dzivandudzike, saLCD , OLED , uye Super AMOLED .
Cherechedza: SecureCRT, mutengi weTelnet, ainzi kunzi CRT asi haina chokuita nevanotarisa CRT.
Nzira yekuti CRT Vatariri Vanoita Basa
Iko kune magetsi matatu e electron mukati mekuongorora kweRT yemazuva ano inoshandiswa pakutsvuka, tsvuku, uye bhuruu. Kuti kuve nomufananidzo, vanopfura magononi pa phosphor kumucheto wepamberi. Inotanga kumusoro kwekumucheto kumucheto kwerwindo uye inofamba kubva kuruboshwe kuenda kurudyi, imwe mutsara pane imwe nguva, kuzadza vhizha.
Apo phosphor inogumburwa nemakombiyuta aya, inoita kuti vashande pane dzimwe nguva, pane mapikisiki, pane imwe nguva yakawanda yenguva. Izvi zvinogadzira mufananidzo unoda kushandiswa uchishandisa musanganiswa wemavara matsvuku, bhuruu, uye mavara.
Apo rimwe rwonzi rinobudiswa pahwindo, mabhota e electron anoenderera mberi neainotevera, uye unoramba uchiita izvi kusvikira zero rose rakazadzwa nemufananidzo wakafanira. Mhedziso ndeyekuti nzira inokurumidzira zvakakwana kuti iwe unongoona mufananidzo mumwe chete, kana uri mufananidzo kana fomu imwe muvhidhiyo

A CRT screen refresh rate inotarisa kuti kazhinji gadziriro yacho ichazorodza sei chinyorwa kuti ibudise mufananidzo. Nemhaka yekuti phosphor inopenya inogadziriswa isina kusimbiswa kunze kwekuti chivharo ichi chivandudzirwa, purogiramu yakaderera yekuvandudza ndeyekuti vamwe vatariri veRCT vanowanzotarisa kana kuti kunze kwenzvimbo, migwagwa inofamba.
Chii chiri kuitika mune izvozvi mamiriro ekugadzirisa anozorodza zvishoma nezvishoma zvokuti unokwanisa kuona zvikamu zvipi zvesvhenekeri zvisati zvaratidza mufananidzo.
Vatengesi ve CRT vari pangozi yemagetsi ekugadziriswa sezvo magnet ndiyo inobvumira kuti magetsi aende mukati mekuona. Izvi zvinopesana nehutachiona hutsva seLCDs.

Mukati reCRT huru uye ine simba haisi chete electron emitters asiwo kuisa pfungwa uye kushandura mapiritsi. Izvo zvipfeko zvose ndizvo zvinoita kuti CRT iongorore zvakakura, saka nei zvitsva zvitsva zvinoshandisa nzira dzakasiyana-siyana dzakadai seOLED, inogona kunge yakaonda.
Flat panel inoratidza seLCDs inogona kuitwa kuti ive yakakura zvikuru (inopfuura 60 ") apo CRT zviratidzo zvinowanzokomberedza 40" papamusoro.
Mamwe eCRT Uses
CRT yakashandiswawo kune zvisiri izvo zvinoratidzira, sezvinochengetedza deta. IWilliam tube, sezvazvaidanwa, yaiva CRT inogona kuchengeta dhinari ye data.
The .CRT file extension inonyatsosiyana nekombiyuta yekuratidzira, uye inoshandiswa kushandiswa kweSecurity Certificate file format. Websites dzinoshandisa ivo kuti vimbise huzivi hwavo.
