Kutheni onjalo umgca sombane ebizayo

Ukuya kwi umfanekiso CRT yi kwikhusi, yaye abaphulaphuli yakwazi ukunandipha usasazo zakho ozithandayo, kufuneka ithunyelwe umqadi electron, looped indawo yayo yonke. Umgaqo nokusebenza esweni okanye TV, apho element libonisiweyo a cathode ray tube, Kulula ukuba asondeze umzekelo izixhobo abamnyama nabamhlophe.

Ngoko ke, lo mfanekiso kwikhusi ukhandwa ingongoma nje enye, kunye rhoqo aphezulu runs malunga amakhulu lemiqolo. Lo mfanekiso jikelele sinako ukubona ngenxa inertia ngayo imizimba yethu.

Ukongeza, umfanekiso ukuba onamandla, kwaye ufuna ukutshintsha yabasebenzi. Umqadi electron iqhuba umgca nge umgca ukusuka phezulu ukuya ezantsi kwakhona kuba iqhutywa lo mhlaba otsalayo eveliswa yi jiko kwinkqubo aphambuke. Ukuze oku kunjalo, kufuneka utshintshe kwi omiyo njalo ethile.

circuit TV Classical luquka amacandelo ahlukeneyo: line amandla isakhelo ukukrwaqula, isitishi serediyo, iyunithi yolawulo, amandla njalo imodyuli chrominance ukuba akwamkele umbala. Eyona nto iphambili unit umgca isixhobosovavanyo lwemifanekiso enqamlezileyo a sombane. Xa nomabonakude mihla oko kudla kudityaniswe yakha ombane. injongo yawo - ukubonelela pulses sawtooth ngayo umbane, ezinikwa kwinkqubo aphambuke coil. ombane wokuphindaphinda, shelwe zezindlu efanayo njengoko sombane umgca, uvelisa a phezulu, phezulu ukuya kilovolts 27 nokukhawulezisa ombane olunika yokunyusa elektroni kumbutho wabo imaski isikrini, phosphor camera. Ngoko, yena, anikwe ityhubhu umfanekiso esebenzisa ophezulu-ombane zigqunyiwe nghena ebizwa ngokuba "ibala," ukukhusela umfowunelwa Ukuqhekeka lwezindlu.

Transformer oxwesileyo ekhwele kunye yakha (TDKS) kukho inani engathi ezenza iziganeko zolawulo olongezelelweyo. Ezi ziquka ugxininiso adjustable kunye ubukhulu le ombane lunikezelo, kwaye coil blanking blanking yekhusi kufuneka ubonakale.

Ngoko ke, amaqela amabini engathi kwenkqubo ukuphambukisa ibhola inika yeraster scan nkqo (HR, CR) kunye tye (tyaba, CP). Ngenxa ukwakheka kwalo kusondele kakhulu isikwere, kodwa bengabonakali ncam ayifani kuyo. Oku kuphambuka ibangwa umahluko umgama ukuba electron kufuneka boyise kwindlela eya imaski. Ukusondela ekupheleni kwekhusi, ngoko ke ngakumbi, yaye CRT flat screen ubunzima kule isiphene ukuya kakhulu kuyaphi kunezixhobo "abadumileyo". Line transformer ngokusebenzisana yakha kunye nenkqubo aphambuke kukho ulawulo ngenyameko uhlengahlengiso into, emva koko ukufiphala iba ubuncinane.

TDKS kwiimfuno ezisemgangathweni ophezulu kakhulu, ubude ukusebenza oluchanekileyo yonke kwisamkeli umabonwakude ixhomekeke kuyo. voltage eyakhiwe ngohlobo lwendibano potted kwaye ayikwazi inokulungiswa, ukuze bonke abafowunelwa lwangaphakathi phakathi engathi kufuneka oluthembekileyo kakhulu.

CP node odla uninzi lwamandla ndiyaphela TV kube kwisiqingatha ixabiso layo yonke.

Njengaye nawuphi na isixhobo zokuqala, umgca sombane sele engundoqo nosiba lisebenza ezingundoqo apho jiko zibekwa. Ukwenzela ukunciphisa ubungakanani, nto yenziwa ferrite olukhethekileyo conductivity high ngemagnethi.

Kuba zonke ezi zizathu TDKS - ukubuyisela udumo kuyabiza kakhulu emva CRT, imfuneko ezakheke xa TV ilungiswe.
