Waa maxay Tube Cathode Ray

Waxaa laga yaabaa in ay jirto ma jirto qof oo kale kuwaas oo noqon lahaa ee uu wajahay qalabka, design ka mid ah taas oo ka mid ah tuubo ray cathode (ama CRT) nolosha. Haddaba xal la mid ah si firfircoon lagu badalay dhigooda dheeraad ah oo casri ah oo ku salaysan qaab crystal dareere (LCD). Si kastaba ha ahaatee, waxaa jira tiro ka mid ah meelaha ay tube ray cathode ah weli waa lagama maarmaan. Tusaale ahaan, in oscilloscopes-sax sare LCD aan la isticmaali Karin. Si kastaba ha ahaatee, mid ka mid ah wax waa cad yahay - qalab warbixin horumarka bandhigay ayaa ugu danbeyn waxay keeni doontaa in failure guud ee CRT ah. Waa arrin waqti.

tube ray Cathode: taariikhda dhicitaanka

discoverer The qaadan laga yaabaa Yu Plucker, taas oo 1859 sano, daraasadda of dhaqanka ee biraha la saamaynta kala duwan dibada, ugub ah helay shucaaca (hawada) qayb ka hoose - electrons. alwaaxdii saqafka haysay walxaha la sameeyay ayaa lagu magacaabay rays cathode. Waxa uu sidoo kale soo jiideen muuqaalka kore ee hawada la arki karo walxaha qaarkood (phosphor) oo xiriir la alwaaxdii saqafka haysay electron, kuwaas oo dareenka. CRT Modern awood u abuuraya image ah ay sabab u tahay labadan helay.

20 sano ka dib, waxaa la helay siman in jihada mooshin ka mid ah electrons timaada waa la xakameyn karaa beerta dibadda ah magnetic. Tan waxaa si fudud u sharxay haddii waxaannu xusuusan nahay in ka sidayaal mas'uul ka xun lagu gartaa dhaqaaqin beerihii magnetic iyo korontada.

In 1895, Karl F. Braun safeeyey maamulka ee tuubada, oo sidaas ay awoodaan in ay bedesho dulinka ah ee jihada socodka walxaha ee ma aha oo kaliya beer nidaamka, laakiin sidoo kale muraayad gaar ah in loo wareejiyo karo, taas oo kor u furay rajada cusub isticmaalka been abuurtay ah. In 1903 godu Venelt kaalinta gudaha koronto cathode tuubada qaab dhululubo ah, taas oo suurto gal ah si loo xakameeyo xoogga daadanayo timaada.

In 1905, Einstein diyaariyey isla'egta xisaabinta saamaynta photoelectric, iyo ka dib markii 6 sano waxaa la soo bandhigay socda qalab kala iibsiga image meel fog. Dogobka ahaa gacanta by beer magnetic, iyo amarka capacitor of qiimaha nuurka.

Inta lagu jiro bilowga ee wax soo saarka ka mid ah tusaalayaasha ugu horeysay ee warshadaha CRT waxaa diyaar u ah in la abuuro screens leh dadab weyn ma ahaa, sidaas weynaynaya lenses loo isticmaalaa sida tanaasul.

Qalab tube ray cathode

Tan iyo qalabka wax laga badalay, laakiin isbedelka waa evolutionary ee dabiiciga ah, sida jiro wax aasaas cusub oo dabcan ah ee shaqada ayaa lagu daray.

jirka Glass bilaabmaa shaashad toobinta tube kordhin la xirrira. The qalabka image midabka, dusha hoose waxaa dahaarka leh kula tallaabo gaar ah saddex nooc oo phosphors (Red, Green, Blue), siinta color luminescence a at dogob electron galo. Iyadoo la raacayo, waxaa jira saddex cathode (qoryaha). Si inay gacan bir ah ku electrons defocus iyo siiyaan dogob doonayo hadda galaya dhibic la doonayo shaashadda u dhexeeya cathode iyo nidaamka lakabka phosphor qataarrada birta diyaarin - maaskaro. Waa in la la Stencil la barbar dhigo karo, iska jar oo dhan aan loo baahnayn.

On dusha sare ee hawada electron cathode u kulul bilaabmaa. Waxay ku degdegin xagga anode ah (koronto ay la socoto lacag fiican), ku xiran qaybta toobinta ee tuubada. Dheeraad ah, alwaaxdii saqafka haysay waxaa diiradda gariiradda gaar ah oo ma waxaan gelayaa berrinkii nidaamka darbo ah. Isagoo maraya shabaggeedii on dhibcood la doonayo shaashadda dayrta, keenaya diinta ee ay tamar ogeed Nuurka.

technology computer

Mishiinada la tube cathode-ray hubkaas ayaa loo isticmaalaa in nidaam computer ah. lillaahinimada of design, isku halaynta sare, midabka sax ah, iyo dib u dhac lahayn (LCD furta jawaab millisecond isla) - taasi waa ay faa'iido ugu weyn. Recently, si kastaba ha ahaatee, sida hore u soo sheegnay, CRT waxaa ku barakacay kormeerayaasha LCD ka dhaqaale badan oo ergonomic.
