Ziva chiedza cheRGB cheMuongorori weganda
RGB yakagadzirwa kubva papfungwa yekupenya kwemavara. Mukutaura kwevanhuwo zvavo, nzira yayo yekusanganisa mavara yakafanana nemwenje mitsvuku, yegirini, neyebhuruu. Kana mwenje yavo yakabatana, mavara acho anosanganiswa, asi kupenya kwakaenzana. Huwandu hwekupenya kweviri, kusanganiswa kwakawanda ndiko kupenya kwakakwira, kureva kusanganisa kwekuwedzera.
Pakuisa mwenje mutsvuku, girini nebhuruu panzvimbo ine mwenje mitsvuku, girini nebhuruu, nzvimbo inopenya zvikuru yemavara matatu epakati ichena, uye hunhu hwekusanganisa kwekuwedzera: kuisa mwenje mutsvuku, ndiko kunowedzera kupenya.
Imwe neimwe yenzira nhatu dzemavara, dzvuku, girini, nebhuruu, yakakamurwa kuita mazinga 256 ekupenya. Pa 0, "chiedza" ndicho chisina kusimba - chinodzimwa, uye pa 255, "chiedza" ndicho chakanyanya kupenya. Kana ma greyscale ane mavara matatu akafanana, ma grey tone ane ma greyscale akasiyana anogadzirwa, kureva kuti, kana greyscale ine mavara matatu iri 0, inenge iri dema rakasviba; kana greyscale ine mavara matatu iri 255, inenge iri white tone yakajeka.
Mavara eRGB anonzi mavara ekuwedzera nekuti unogadzira machena nekuwedzera R, G, naB pamwe chete (ndiko kuti, chiedza chose chinodzoserwa kuziso). Mavara ekuwedzera anoshandiswa mumwenje, terevhizheni uye makombiyuta. Semuenzaniso, zviratidziro zvinoburitsa ruvara nekubudisa chiedza kubva kuphosphors dzvuku, girini, nebhuruu. Ruzhinji rwe spectrum inooneka inogona kumiririrwa semusanganiswa wechiedza chitsvuku, girini, nebhuruu (RGB) muhuwandu hwakasiyana uye simba. Kana mavara aya akabatana, cyan, magenta, neyero zvinogadzirwa.
Mwenje yeRGB inoumbwa nemavara matatu makuru akabatanidzwa kuti agadzire mufananidzo. Pamusoro pezvo, kunewo maLED ebhuruu ane phosphors yeyero, uye maLED e ultraviolet ane phosphors yeRGB. Kazhinji, ese ari maviri ane maitiro awo ekutora mifananidzo.
Mwenje we LED chena ne RGB LED zvese zvine chinangwa chimwe chete, uye zvese zvinotarisira kuwana simba remwenje muchena, asi chimwe chinoratidzwa zvakananga semwenje muchena, uye chimwe chinoumbwa nekusanganisa tsvuku, girini nebhuruu.
