Chii Cathode Ray Tube

Zvichida hakuna munhu akadaro uyo aizova muupenyu hwake watarisana mano, magadzirirwe rinosanganisira cathode ranzi chubhu (kana CRT). dzakafanana zvingaitwa zvino vari kushingaira kuitwa ne zvakawanda vazvo ano pachishandiswa mvura sekristaro kuratidzirana (LCD). Zvisinei, pane vakawanda munzvimbo umo cathode ranzi chubhu richiri chinokosha. Somuenzaniso, mune mukuru-zvakarurama oscilloscopes LCD haagoni kushandiswa. Zvisinei, chimwe chinhu chiri pachena - kufambira mberi mashoko vanoratidza mudziyo achapedzisira kutungamirira chaunobura yacho CRT. Inyaya nguva.

Cathode ranzi chubhu: nezvenhoroondo chiitiko

Akawana vangafungidzira Yu Plucker, izvo 1859 gore, kudzidza kwemaitiro nesimbi dzakasiyana-siyana zvokunze zvinokonzerwa, kutanga vakaona nemwaranzi (akabuda) kuti zvokutanga nezvimedu - maerekitironi. Kuvakwa PARTICIPLE matanda dzainzi cathode mwaranzi. Iyewo vakachera kuteerera chitarisiko rinooneka akabuda zvimwe zvinhu (phosphor) uchikurukura izvi Erekitironi namatanda. Modern CRT anokwanisa pakusika chifananidzo nokuda izvi zviviri zvakawanikwa.

Pashure pemakore 20, zvave kuwanikwa empirically kuti inofamba nenzira chaibwinya maerekitironi zvinogona kudzorwa ne ane kwokunze remagineti. iri nyore Izvi zvinotsanangurwa kana tikayeuka kuti akaipa mutariri vatakuri dzinoratidzwa anozunungusa rinobva uye dzemagetsi minda.

Muna 1895, Karl F. Braun yakanatswa utariri ari chubhu, uye saka akakwanisa kuchinja Vector pamusoro PARTICIPLE kuyerera mirayiridzo haisi chete munda wegadziriro, asiwo girazi chairo kuti inogona zvayaitenderera paguyo, iro netariro zvachose matsva kushandisa nokugadzirwa. Muna 1903 godu Venelt akaiswa mukati chubhu cathode electrode ari muchimiro humburumbira, zvichiita kudzora kusimba ari chaibwinya okuyerera.

Muna 1905, Einstein akagadzira mukana wokuti vanhu vanga kuti pakuverenga ari photoelectric zvazviri, uye pashure 6 makore Zvakaratidzwa achimhanya mufananidzo kuchinjirwa mudziyo kure. Beam hwaidzorwa noruoko remagineti, uye capacitor rokuchengeta kupenya ukoshi.

Munguva pakatanga kugadzirwa okutanga yemashoko CRT indasitiri zvakanga zvisiri agadzirira kusika sefa ane makuru diagonal, saka kukudza lenses senzira nzwisisa.

Midziyo cathode ranzi chubhu

Sezvo mudziyo chakagadziridzwa, asi kuchinja vari shanduka mune zvakasikwa, sezvo hapana vangasimudzira chitsva mukufamba basa yave akawedzerwa.

Glass muviri chinotanga conical chubhu chiwedzerwa Anoumba sikirini. Ruvara mufananidzo mano, yomukati pamusoro zvinenge zvakazara imwe nhanho mhando nhatu phosphors (Red, Green, Blue), zvichipa luminescence ruvara panguva Erekitironi danda anopinda. Saizvozvowo, pane vatatu cathode (pfuti). Kuti Anosakurawo kunze maerekitironi defocus uye zvinopa zvandinenge danda ano kupinda aida pfungwa iri chidzitiro pakati cathode uye phosphor rukoko ezvinhu akaronga simbi mbariro - chifukidzo. Unogona kuenzaniswa rakanyorwa mabhii rinowanzodhinda mapepa, akagura zvose basa.

On penyika huru cathode Erekitironi achine kunotanga. Dzinobhururuka kurutivi anode (electrode uine mutariri), zvakabatanidzwa kune conical chikamu chubhu. Uyezve, matanda vari pfungwa inokosha coils uye kuwira kumunda Kutsauka hurongwa. Nomunyika chendarira kuwa pamusoro aida pfungwa pamusoro chidzitiro, kukonzera kutendeuka yayo kinetic simba kupinda chiedza.

kombiyuta michina

Monitors vane cathode-ray chubhu zvinonzi nevakawanda kushandiswa makombiyuta. Kujeka design, mukuru kuvimbika, ruvara yakarurama, uye kunonoka (zvakafanana millisecond norudaviro chizvaro LCD) - iri nani yavo huru. Munguva ichangopfuura, zvisinei, sezvo kare ambotaurwa, kuti CRT iri misha mari yakawanda uye ergonomic LCD monitors.
