CRT-aroturuki: whakaahuatanga, te āhuatanga matua o te pūrere

CRT-aroturuki - he pūrere, e hāngai ana nei i runga i te ngongo hihi pito tōraro. I whakawhanakehia tēnei hangarau i roto i te 1897 i te pūtaiao Tiamana F. Brown. I te tīmatanga i hanga reira rite te mea motuhake hangaia mō te ine tauutuutu nāianei (tīkorikori).

CRT-aroturuki me tona hoahoa

Ko te huānga taketake o tenei pūrere ko te kinescope. Kei a ia ko te ngongo hermetically hiri karaihe i nei nekehia atu hau te (i.e., te mārua roto reira). He papatahi me whānui tetahi mutunga o te ngongo - ko te mata, me te tahi atu - te roa me te kuiti - te reira kaki. pani te taha ki mua o te roto o te ngongo e ki te hanganga phosphor (e hāngai ana i runga i yttrium me erbium). Ko te huānga muri ko te irahiko pū CRT-aroturuki, i nei i raro i te mahi o te mara hiko rau te rere o ngā irahiko, reira puta he whakapakoko i runga i te mata. matūriki Elementary tika na waenganui i te grille whakarewa me te patua te roto o te mata karaihe pani ki ira phosphor o tae rerekē. whakarato pūnaha deflection Special he hit ōrite te kurupae i runga i te mara mata. Ko o rua momo pūnaha faahuri: nohoanga me te toroidal. Kei o inductors, whakanohoia i roto i te kaki o te kinescope te pūnaha.

huānga Next tautuhi CRT-aroturuki, he anga poraka me te matawai raina. Tenei kōpuku Ko te puna matua o te ngangau i roto i te whānuitanga auau whakahaere. Ko te mana pau e enei kōpuku - tetahi o nga āhuatanga nui e Me whakaaro ka hoahoa i te aroturuki CRT. Ko te mema i muri ko te modulator kaha, e tahi ki te pūnaha tere mahi i runga i te parau tumu o te rerekētanga pea. Nā ki enei kōpuku whiwhi irahiko pūngao, wahi o e noho i runga i luminescence o te phosphor.

RGB-hangarau

Ko te tikanga kei roto i te tae CRT-aroturuki e toru pu irahiko, me taetahi - kotahi. Enei hāngai pū tuatahi tae: matomato, whero, me te puru. Ka taea e ratou huinga waihanga he maha mure ore o atarangi me ngā tae. Hei whakahaere i te CRT hiahiatia te hikohiko mana, e whakatau i te kounga o te aroturuki. E rerekētanga rite hikohiko, whakaputaina e ngā kaihanga, ko te paearu mō te whakatau i te rerekētanga i waenganui i CRT-te aroturuki, ahakoa te meka e te ngongo hihi pito tōraro i roto ia ratou, ko te taua. Ko te kupu, E faatae mai ia pū he awa e pānga te mata o rerekē phosphor tae. Ko te kurupae irahiko o te tae taua kia pā anake nga āhuatanga o te tae kotahi. Hei whakatutuki i rite tenei kurupae mahi mā te whakamahi i te kanohi motuhake, te hanganga o nei tei runga i te momo o te ngongo pikitia.

Tapia CRT-te aroturuki

Ko te malfunctions taketake CRT-pūrere he mana supply arā. Nuinga o ngā wā he tika ki ongo mana tenei. Ki te kore te reira i te supply mana, na te pea te nuinga ki te puta me te kino ◊oatu fakataha ki ētahi atu kōwae, hei tauira, he takahi o te tae, image distortion. I tua atu ongo, ai kore o te aroturuki i e maha mihini pakaru (aro) te pānga o ngā mātāpuna o radiation hiko, puehu aroturuki pukā, hoholo pūtau. Ka taea e Tūkinotanga pāmahana arahi ki te kore o te poari tukatuka tohu ataata me te pūnaha atahanga. Tūkinotanga tōtika matawai whakapae ko e tika ana ki te wehenga i roto i te ara iahiko ngaohiko tiketike, me te TDKS. Ko tētahi o nga take whakahuatia tītohunga tu puehu.
