Ubani owasungula le ithelevishini, futhi ngamuphi unyaka?

Namuhla singethuki ubani TV. Leli bhokisi noma ngisho nezisekelo ezincane, okuyinto ikuvumela ukuba sibonise izithombe wathutha. Kunzima ukucabanga ukuthi nje kancane eminyakeni engaphezu kwekhulu edlule, lobu buchwepheshe wayengekho isimiso. ngiyabonga kuphela omningi ucwaningo siyakwazi ukujabulela TV.

Mayelana nabantu kwasinika ithuba ukuze uthumele izithombe bekude, futhi kuzoxoxwa ngani kulesi sihloko.

Ngesikhathi impande

Ubani owasungula le ithelevishini, futhi ngamuphi unyaka? Baningi abantu bebuzwa lo mbuzo, kodwa hhayi wonke umuntu angamnika impendulo enembile.

Kusengenzeka ovulekile futhi umbuzo lapho ithelevishini yasungulwa. Izimpendulo zingase zingabi esiyingqayizivele. Lokho kungenxa yokuthi akukho umuntu oyedwa yasungulwa TV lokuqala. Kuyinto umsebenzi onzima owenziwa abaningi.

Lapho yasungulwa ithelevishini? Ngenxa yalesi kwesokudla ukulwa eziningi emazweni, ngalinye elikwazi ngasebenza ngalolu daba lonke ibutho ososayensi. Kodwa izinto zokuqala kuqala.

Indlela Bonke baqala

Eyokuqala kakhulu owasungula ithelevishini, angabhekwa wemithi Swedish okuthiwa Jens Berzelius. Usosayensi esebeké eziningi ucwaningo endaweni yokucwaninga, ukuze kwatholakala isici ezazingaziwa, ethiwa "selenium".

Ukubaluleka kwalokhu mcimbi awukwazi babenesibindi esikhulu. Kwaphawulwa ukuthi lapho lesi sakhi uqhuba zamanje kagesi kuye esebenza kwalo ubuningi ukukhanya.

Ngaphandle kwayo, ukudluliswa image ebandleni bekungekhe kukghonakale.

Kusukela ithiyori - ukuzijayeza

Boris Lvovich Rozing - yilokho owasungula ithelevishini - uzobe wagomela-mlando. Futhi kuyoba neze iqiniso.

Biography of the physics kanye umsunguli empeleni kwasinika ithuba ukuchitha kusihlwa isikrini blue, kubalulekile ukuba uhlole kakhulu.

Boris Lvovich Rozing wazalwa ngo ayizinkulungwane ngonyaka namashumi ayisithupha nesishiyagalolunye ayisishiyagalombili Petersburg.

Cishe zonke izinsuku zokuhamba kwakhe wayehumusha nomsebenzi we-Institute. Lobu buchwepheshe Petersburg Arkhangelsk amaHlathi Engineering, nabanye abaningi, lapho emenywa njengenhlangano womfundisi zokuhlonipha. Usosayensi bavikela mqondo yakhe.

Umsebenzi wakhe uye enikelwe ekutadisheni uzibuthe, umsakazo, ugesi, ensimini yamangqamuzana, izinto ferromagnetic, quantum physics, Dynamics.

Umqondo ukuze uthumele isithombe ibanga wafika Borisu Lvovichu e ayizinkulungwane ngonyaka ayisishiyagalolunye nesikhombisa asibhozo anamanci. ucwaningo lakhe akakwazanga wacabanga ngaphandle ngamapayipi cathode-ray, eyayisanda kufika yasungulwa, kanye izifundo we Photoelectric umphumela physics Aleksandra Grigorevicha Stoletova.

impumelelo yakhe ekutadisheni udaba zazinkulu. Kakade ngonyaka zomhlaba nesishiyagalolunye engamakhulu lwesikhombisa yayimelelwe ezithwetshuliwe ubuchwepheshe usebenzisa tube cathode-ray nge screen Fluorescent futhi ligijima izibuko. Inventions Physics ziye lobunikazi neyaziwayo e-United States, Great Britain eJalimane. Okuhlangenwe nakho kwaba isibonisi imivimbo grey esikrinini abamnyama. Kubonakala kanjalo elula. Kodwa ngaleso sikhathi kwaba intuthuko enkulu. Mayelana usosayensi abanamakhono ukhuluma emhlabeni wonke.

amane nje kweminyaka physics wakwazi uthumele isithombe kude. Cishe, noyedwa kubafundi akungabazeki ukuthi ubani owavela ithelevishini.

Esikhathini esifanayo eyodwa namakhulu ayisishiyagalolunye namashumi ngonyaka weshumi nanye Rosing wenze ushintsho kusuka mechanical kuya izinhlaba.

Kwaze kwaba sekufeni kwakhe ngo-nesishiyagalolunye amathathu nantathu ngonyaka physics lalihlala ukudala futhi bathuthukise imishini yabo, nezindlela entsha bashintshashintshe izwi, bahlabe amashubhu nelezifunda design.

I ucwaningo kuqala nge isithombe

Ubani owasungula le ithelevishini yokuqala, ngoba umsunguli odumile waseMelika, uMnu Kerry, ngokuvumelana abacwaningi abaningi. Imiphumela zokuhlolwa yakhe kwaba lihlelo lokuthoma lokusebenza, lapho wakwazi ukudlulisa ongaqondakali, kodwa namanje isithombe.

Mayelana owasungula ithelevishini, ungaqala i inzalo ukungqubuzana umsunguli Paul Nipkow. Okuhlangenwe nakho kwakhe kwangaleso kwakufunwa ngcono, nakuba isimiso ukusebenza idivayisi efanayo imishini uMnu Kerry. UPawulu wanikeza indlela yakhe ngokuthi "umfanekiso enemininingwane". Egcekeni wema ngonyaka namakhulu ayisishiyagalombili namashumi ayisishiyagalombili nane.

elithi entsha

Igama elithi "ithelevishini" udumo unjiniyela Russian Konstantin Dmitrievich WasePheresiya.

Ngaphambi kwalokhu, ososayensi baye basebenzisa izinkulumo eyinkimbinkimbi njengezimpi "dalnovidenie" noma "izibonakude kagesi".

Kukholakala ukuthi wayengumuntu wokuqala ukwethula kube ukusetshenziswa ngo-August 1900. Lokhu kwakwenziwa phakathi kohlaka International Electrotechnical Congress e-Paris. Igama bathandile amaqembu, futhi ngokushesha wayendlala esiyingini bakho emuva ekhaya.

Lo mbiko "ngalo mbono buqamama," olwenziwa ngesiFulentshi.

Onyakeni owawandulele, uKonstantin Persky wathola igunya lokwenza eyodwa yezindlela yokudlulisela isithombe. Eshukunyiswe impumelelo, unjiniyela ngomdlandla watshela ozakwabo European mayelana namathuba enkulu kunganikeza esintwini ubuchwepheshe yayo.

Mayelana ososayensi ukwazana. kwavela Konstantin Dmitrievich kusukela emndenini ezihloniphekayo, okhokho baso babengabapristi omkhulu kakhulu Prince Dmitry Donskoy.

Ngaphambi kokunikezela ukuphila kwakhe yokusungulwa, Persky ayikwazanga ukuqedela Mikhailovsky wezikhali Academy, futhi zizosetshenziswa lwati lolutfolakele phakathi nempi Russian-Turkish, lapho ngisho waklonyeliswa Order "Ukuze Mendi".

Ngemva ababevela empini Konstantin Dmitrievich ezakhetha ukuhlanganyela indlela wezempi isayensi ngesikhathi esifanayo ube uyilungu elisebenzayo Petersburg imiphakathi lobuchwepheshe kagesi kanye.

I esiphawuleka kakhulu emsebenzini wakhe baba umbiko olunzulu enesihloko esithi "Isimo yamanje yempikiswano elektrovidenii buqamama", okuyinto wayemelela ngempumelelo etikhungweni letahlukahlukene ezemfundo ezweni nasemazweni aphesheya.

Nakuba yemvelo ka umsebenzi benza kahle ukuhlakulela usosayensi futhi emkhakheni lempi. Ikakhulukazi, wathola indondo ye Fair Chicago Wezwe idivayisi isixwayiso esivela izama ukungena egumbini imfihlo.

Akubi womqalisi ngo-1906.

Imiphumela ukuthi ayemakhulu amathemba ababenawo

On umbuzo lapho uJohane Logie Baird yasungulwa ithelevishini, zikhona abalandeli ithalente lakhe, okuyinto kugcwale umlomo ukuthi lesi nesishiyagalolunye Ngonyaka wamashumi amabili nantathu. Yingaleso sikhathi-ke ukuthi usosayensi kwaba ukwazi ukudlulisela isithombe ikhebuli esifakiwe nozakwethu, Charles Jenkins, United States.

Kodwa nomabonakude - iyona ukudluliselwa amaza kagesi ngokusebenzisa izintambo hhayi kuphela. Ukuze agijime kubo kwasekuqaleni Udinga ikhamela TV.

Ochwepheshe bathi ngokuqiniseka, yasungulwa TV usosayensi Russian okuthiwa uVladimir Zworykin, ngo-1931 ezakhiweni we Radiocorporations ibhizinisi of America. Kodwa-ke iphuzu moot, ngoba cishe ngesikhathi esifanayo, kwenye umsunguli Fil Farnsuort, ukwakha idivayisi efanayo.

Emlandweni walondoloza igama yomnikeli usosayensi Russian ababekholwa umqondo wakhe Futuristic kakhulu futhi Amazing - kungcono Devid Abramovich Sarnov, iU.S. Signal Corps nosomabhizinisi. Kwaba ngenxa yakhe zezimali zomhlaba babone iningi ezisunguliwe uVladimir Zworykin.

Eyokuqala ikhamera yevidiyo

Ikhamera wokuqala u "inkoskop" futhi "tube Fine-okuxhunyanwa."

Kuyo yonke le minyaka nane esilandelayo, idivayisi uzohanjiswa wokubuyekeza sina futhi kuyodingeka isakhiwo esifana nesika esetshenziswa amadivaysi yesimanje.

Babeka isisekelo tube cathode-ray, ngokusebenzisa okuyilokho, eqinisweni, isithombe idluliselwa ku umbukeli.

umbala ithelevishini

Abaningi bakholelwa ukuthi ithelevishini umbala kusungulwe unjiniyela Soviet Ovanesom Adamyanom.

Emuva ngo-nesishiyagalolunye namashumi Ngonyaka wesishiyagalombili umsunguli wathola igunya lokwenza wadala kudivayisi mkhosi. Ukusungulwa bangadlulisela ngaleso sikhathi imibala emibili kuphela.

Noma kunjalo, kuwukuhlakanipha ukucabangela ukuthi uJohane Logue Brad labo owasungula le ithelevishini ngombala. Lo muntu wajoyina izihlungi oluhlaza, blue and abomvu ukuze bakwazi ukudlulisa ezihlukahlukene inhlanganisela.

Amaqiniso ethakazelisayo TV

Izipikha omnyama nomhlophe ithelevishini ukusebenzisa lipstick oluhlaza. umbala obomvu esikrinini wabheka eliphaphathekile kakhulu futhi igezwa. Ngemva eziningi ucwaningo futhi Isivivinyo wafinyelela esiphethweni ukuthi green umbala ivumelane kakhulu.

Mayelana lapho futhi hlobo luni ukudluliswa wadedelwa lokuqala, izingxabano kukhona ngombala. Umbono ezivamile ukuthi kwaba Carling webhola.

okusakaza Okugcwele unomphela okwaqala ngonyaka e-United States nesishiyagalolunye engamakhulu wamashumi amane futhi.

Isicelo lokuqala commercial eshicilelwe ngo-1951 e-United States. Kwakuyisenzo esasibonisa show bezijabulisa osaziwayo kuyi-CBS.

Kufinyeta idatha

Esihlokweni kukhona amagama abantu abaningi kakhulu owayesebenza ngezikhathi ezihlukahlukene wocwaningo yamazwe ahlukene futhi amazwekazi. Ngamunye wabo negalelo elikhulu ekuthuthukiseni ithelevishini. Ngaphandle imisebenzi lezi ezinkulu, abantu uzibophezele Awukwazi ukudlulisela izithombe.

Akubalulekile ukwaba umuntu oyedwa. Ngenxa zonke lezi izifundo, thina manje ithuba lokujabulela evamile ezifana ithelevishini.
