Chokutanga, regai achiongorora zvaive abbreviations. Saka, shoko rokuti "CRT" rinoreva Erekitironi danda kana, sezvo isu akanongedza apfuura, cathode chubhu (kubva Chirungu CRT -. Cathode Ray-Tube). Kazhinji, kana shoko "chubhu" vanhu vakawanda humburumbira, pamigumo iyo hakuna rusvingo. Kunze chokwadi kuti kwakadaro CRT tarisisa, zvakakodzera kutaura kuti iyi nyaya yakadaro mufananidzo ndeyenhema. Nokuti Maumbirwe chubhu mairi iri kure cylindrical ndege uye kunosvika kune rimwe divi. pemvura ichi chinomiririra chikamu pamberi regirazi, mumwe pairi mifananidzo vari aumba. The divi chomukati mugove ichi zvemapuranga aine zvinhu chaiyo - phosphor. Its yakasiyana chinhu ndechokuti kana achipinda parukova mhosva inoramba iri yavo payo kinetic simba inongoitika nzira dzikwanise chiedza. Saka, mumwe CRT tarisisa chinhu mudziyo umo matanda ari Erekitironi nematanda mukati silhouetted mufananidzo chidzitiro. Man anoriona, anoonga akabuda ari phosphor.

Ukuwo chinu anoiswa chidhina electrodes, inonzi kanoni. Ivo kusika norwizi inoramba.

Nemamwe mashoko, CRT tarisisa rine girazi chubhu-pfuti electrodes uye kudzorwa redunhu.

Sezvo chikazozikamwa, nokusanganisa imwe nhamba nhatu zvikuru mavara: mutema, tsvuku uye zvitema - unogona kuwana zvose vamwe, kusanganisira kwerima guru. Ruvara monitors yose nechomukati pose chidzitiro rine pixels, conventionally dzikarongwa mu vatatu vatatu (kutigumbura 3 zvidimbu). Mumwe nomumwe wavo anogona aivhenekere chimwe chezvinhu mavara. Uye electrodes matatu, chimwe nechimwe unoratidza dzavo okuti "pachavo". Mune mamwe Kuti chiedza uye achipfuura navo pamusoro chidzitiro, zvinokwanisika kuti vaumbe ruvara mufananidzo. Sezvineiwo, mudziyo nhema uye chena nepfuti mumwe chete.

Kudzora chekubuda nezvimedu vaishandisa remagetsi Kutsauka uye kutanga kutungamirirwa inofamba akasikwa, nokuda dzingangoitika musiyano.

Sezvo zvazviri zvakaoma kuwana, vachishandisa chaiyo Mutongo rakarurama danda wakawira pamusoro wake pfungwa - chifukidzo. Tichishandisa kutaura, ichi chinhu Perforated afoot pakati chidzitiro uye pfuti. Kune mhando akasiyana Masiki. Neimwe vava mhosva kuratidzwa unhu (yakajeka, chimiro-Pixel pfungwa).

Sezvo pashure kurova sokupenya phosphor nezvimedu zvinoderedza nokukurumidza kwazvo, unofanira kugara kusikazve mufananidzo. Vose kunofambira mberi uye simba. Naizvozvo mwaranzi kuzochera zvakadzama mufananidzo kakawanda por wechipiri. Ndicho akakurumbira Hertz pepuranga kushanda pakuvheneka. The yepamusoro kakawanda, kashoma kuoneka kudzima.

Pari kugadzira CRTs kuti akazotevera kushandiswa yekombiyuta kwaizova kukodzera, sezvo ano LCD zvemichina zvikuru zvinovimbisa. Kunze - kuchiitirwa kushandiswa.
