He aha te mea he ngongo hihi pito tōraro

Mahalo kahore he tangata taua nei e kia i fehangahangai ki te whakaaro, te hoahoa o e ngā te ngongo hihi pito tōraro (ranei CRT) tona ora. Na kei te kaha te whakakapi rite rongoā e ratou ake ritenga hou e hāngai ana i runga i ngā whakaaturanga karaihe wai (LCD). Heoi, i reira e he maha o ngā wāhi i roto i te mea mahuinga tonu he ngongo hihi pito tōraro. Hei tauira, e kore e taea te whakamahi i roto i oscilloscopes tiketike-pū LCD. Heoi, he mārama kotahi mea - e te pūrere whakaatu i te ahunga whakamua mōhiohio iku arahi ki te kore katoa o te CRT. Ko reira he mea o te wā.

Hihi pito tōraro ngongo: hītori o takanga

kia amo TE I Yu Plucker, i roto i 1859 tau, te ako o te whanonga o te konganuku ki ngā pānga o waho, kitea te āhuatanga radiation (paheke) o matūriki pūmotu - irahiko. huaina kurupae matūriki i hanga i hihi pitoiho. Ia ka whakatata hoki whakarongo ki te ahua o te tukunga kitea o etahi matū (phosphor) i roto i te whakapā ki enei kurupae irahiko. Ko te ahei o te hanga i tētahi whakapakoko e tika ana ki enei āhuatanga e rua CRT Modern.

I muri i te 20 tau, kua kitea te reira empirically e taea te whakahaere te ahunga nekehanga o te irahiko whakaputa e te autō waho. Kei te ngāwari faataa tenei ki te mahara tatou e te kawe kino tiaki āhuatanga e neke i te mara autō, me te hiko.

I roto i te 1895, parakore Karl F. Braun whakahaere i roto i te ngongo, a ko te kupu i taea ki te huri i te pere o te ahunga rere matūriki ko kore noa he mara o te pūnaha, engari ano hoki i te whakaata motuhake e taea te koané, i whakatuwheratia ake opuaraa tino hou mo te whakamahi o te tenenga. I te tau 1903 godu Venelt whakanohoia roto te kawehiko ngongo pitoiho i roto i te puka o te rango, hanga reira taea ki te whakahaere i te kaha o te rere tukuna.

I roto i te 1905, i waihanga Einstein te whārite mō te tātai i te awenga whakaahua-hiko, me i muri i te 6 tau kua reira faaite rere image pūrere whakawhiti i te tawhiti. i te mana kurupae i te papa autō, me te tiaki pūnga o te uara wherikotanga.

I roto i te tīmatanga o te hua o te tauira tuatahi o te ahumahi CRT kihai i reira rite ki te hanga i mata ki te hauroki nui, pera i whakanui arotahi whakamahia rite te ngāwari.

Taputapu pitoiho ngongo hihi

Kua Mai kua whakarerekētia te pūrere, engari he kunenga i roto i te natura te huringa, rite reira he mea faufaa hou i roto i te akoranga o te mahi kua tapiritia.

haamata Karāhe tinana ki te toronga ngongo hanga mata koeke. Ko te whakaaro image tae, pani te mata i roto kei te ki te tetahi taahiraa e toru momo o phosphors (Whero, Green, Blue), hoatu he tae luminescence i te kurupae irahiko tomo. Fakatatau ki ai, i reira e toru pitoiho (pu). I roto i te tikanga ki te tarutaru i nga irahiko defocus me te whakarato nāianei kurupae e hiahiatia ana tomo te pūwāhi e hiahiatia ana i runga i te mata i waenganui i te pitoiho me te pūnaha apa phosphor tutaki maitai whakaritea - kanohi. Ka taea te whakarite te reira ki te stencil, hatepea atu tikanga katoa.

I runga i te mata o te pitoiho wera irahiko paheke haamata. rere ratou ki te pitoake (kawehiko ki te tiaki pai), hono ki te wahi koeke o te ngongo. I tua atu, kei te arotahi kurupae pōkai motuhake, me te taka ki roto ki te parae o te pūnaha deflection. E haere ana i te hinga pae kupenga ki runga ki te wāhi e hiahiatia ana i runga i te mata, ka meinga te faafariuraa o tona pūngao neke ki te marama.

hangarau rorohiko

Kei te whānui ngā kaupane ki pitoiho-hihi ngongo whakamahia i roto i te pūnaha rorohiko. Ko te tapatahi o te hoahoa, tika tiketike, tae tika, me kahore e whakaroa (te taua hākonamano whakautu kopu LCD) - ko to ratou painga matua tenei. Aita i maoro a'e, Heoi, rite kua whakahuatia, ngā te CRT te aroturuki i LCD atu economical, me te hāneanea.
