Ngubani owavela umabonwakude. Imibono kulo mba ngenxa ezahlukeneyo kwimbali nobungqina.

Ngelo xesha langoku ixesha uluntu bale mihla ubomi bakhe obuqhelekileyo ngaphandle eendaba. Ulwazi nganye amadoda afumana nge unomathotholo okanye umabonakude, oolindixesha kunye neminye imithombo. Kuzo zonke ndlu kukho TV ukuba langoku ibakala uphuhliso ayibobuchule iluncedo kakhulu intuthuzelo ubuninzi ukuze bachithe ixesha labo mahala.

Imbali kokusungulwa TV uxhokonxa neengqondo ezininzi. Ngubani owavela TV yokuqala, eyakuzisa umphakathi ulwazi oluninzi luncedo? Impendulo yalo mbuzo olula abemi abaninzi bafuna ukwazi. Ngapha koko, ngokuba indalo le bugcisa, eza alungele ukusetyenziswa abaninzi, kwathabatha ixesha elininzi kunye izazinzulu ezininzi baye bazama ukwenza ubomi babantu ezinomdla kakhulu and mobile.

Eyona nto inomdla kakhulu kukuba lo mbuzo ngubani kuqala owavela umabonwakude, akukho impendulo enye. Phela, akukho umdla ukuqaphela ukuba imeko efanayo yabonakala wayila kanomathotholo. Ngubani owavela umabonwakude, kakhulu, ngubani kuqala iyile radio - imithombo eyahlukeneyo banikela iimpendulo ezahlukeneyo. Kakade ke, ukuba kukho umdla phakathi abemi, ophezu kwisifundo apho wenza umabonwakude.

Ngowe-1873, Smith, oyinzalelwane kwilizwe eNgilani, owokuqala wathi ukukwazi semiconductor lohlobo crystalline lwe selenium izinto zobumnini isithuba emnyama ekwazi ukumelana. Oku emva kwethuba wafumana ukusetyenziswa kabanzi kwiinkqubo zikamabonwakude. Ngaphezu koko, umbuzo lowo owavela umabonwakude, eminye imithombo zibonisa ukuba unjingalwazi physics evela Portugal phantsi igama de Paiva, liphuhlise isixhobo ukuba ayihambi imifanekiso ngokuthunyelwa. Kubulungisa kufanele kuqatshelwe ukuba akukho lwaba iskrini ukunika ukhanyiso kwisikhululo eso siwamkelayo umyalezo. Xa 1900 Ekuqaleni kwenkulungwane lokugqibela, edume Isazinzulu A.Enshteyn ekubikwe kakuhle eli isivamvo. Ukususela ngelo xesha, ixesha kamabonakude waqalisa uhambo yayo lobungangamsha kumazwe. Phambi kokuvulwa-nzulu yokugqibela, izifundo ezifanayo ziingcali A.Stoletov. Ngowe-1888, nguye lowo lokuqala bathatha uphuhliso 'iliso zombane ".

imithombo abaninzi zibonisa ukuba, ngubani kuqala owavela TV - oko livela emigrant Russian, VK Zworykin Wazalwa ngasekupheleni 1800 yenkulungwane yangaphambili kwintsapho zorhwebo. Umfundi elungileyo iziqu. Ngexesha izifundo zakhe wayedibana abaninzi abanegama yenzululwazi lizwe lethu. Kodwa ke, ngenxa yokoyika ukubanjwa, ngexesha iMvukelo ebizinyikimisa ilizwe lethu, ndaya US. Kukho kakhulu kwicandelo lookhetshe kunye ukunyaniseka kweli sesayensi wayinikela ukuba basebenze elebhu kwisixeko yePittsburgh. Xa indawo yalowo umphengululi kaRhulumente ngo-1923 wasebenza waza wafunda ukuyilwa ngemibhobho electron yokudlulisela nokufumana izicelo. kweminyaka esibhozo kamva, isazinzulu ngokubambisana kunye nogxa imvelaphi Russian kudala umbhobho serial. It has a photocathode noMosaic izazinzulu ukusombulula umba ukutshintshwa imibala. Basics umbala kamabonakude ibekwe kubo. Kunyaka olandelayo, le shini umbala wokuqala zithe zafakelwa eNew York. Ekuqaleni imi--30 kwinkulungwane yokugqibela Zworykin yenza ingxelo kwintlanganiso ye Radio Engineers of America. Emva kokufunda nokuphulaphula kule ngxelo, iintatheli ezininzi physics Isazinzulu igama le television izinyanya. Kodwa sisazinzulu ngokuthobeka kuphawulwe ukuba nje igalelo lakhe kuphuhliso kunye nokuphuculwa umbala-uhlobo kamabonakude. Ngomhla ekudalweni TV asebenza izazinzulu ezininzi. Ngoko ke, umbuzo wokuba ngubani owavela umabonwakude, ukufumana impendulo ubhalo - izazinzulu nabaphandi abavela kumazwe ahlukeneyo kunye namazwe. igalelo Joint kulwakhiwo components shini izise iinzuzo ezibambekayo eluntwini. Mhlawumbi wonke Bulelani owasungula umabonwakude.
