Kia mōhio ki te rama RGB o teKaitātari Kiri
Ko te RGB i hangaia i runga i te mātāpono o te kanapa o ngā tae. Ki te kōrero noa, ko tana tikanga whakaranu tae he rite ki ngā rama whero, kakariki, me te kikorangi. Ina taupatupatu ō rāua rama tetahi ki tetahi, ka whakaranua ngā tae, engari he ōrite te kanapa ki te. Ko te tapeke o te kanapa o ngā mea e rua, ko te nui ake o te whakaranu ka teitei ake te kanapa, arā, he whakaranu tāpiri.
Mō te taupatupatu o ngā rama whero, kakariki me te kikorangi, ko te mā te rohe taupatupatu kanapa o ngā tae matua e toru, ā, ko ngā āhuatanga o te whakaranu tāpiri: ko te nui ake o te taupatupatu, ko te kanapa ake.
E wehea ana ia o ngā awa tae e toru, te whero, te kakariki, me te kikorangi, kia 256 ngā taumata kanapa. I te 0, ko te "mārama" te mea ngoikore rawa - ka whakawetohia, ā, i te 255, ko te "mārama" te mea kanapa rawa. Ina ōrite ngā uara hina-tae-toru, ka puta ngā oro hina me ngā uara hina-rerekē, arā, ina 0 katoa te hina-tae-toru, koia te oro pango pōuri rawa; ina 255 te hina-tae-toru, koia te oro mā kanapa rawa.
Ka kiia ngā tae RGB he tae tāpiri nā te mea ka hangaia he mā mā te tāpiri i te R, G, me te B (arā, ka whakaatahia te mārama katoa ki te kanohi). Ka whakamahia ngā tae tāpiri i roto i ngā rama, pouaka whakaata me ngā mata rorohiko. Hei tauira, ka puta he tae i ngā whakaaturanga mā te tuku mārama mai i ngā whēwha whero, kakariki, me te kikorangi. Ko te nuinga o te whānuitanga e kitea ana ka taea te whakaatu hei ranunga o te mārama whero, kakariki, me te kikorangi (RGB) i roto i ngā ōwehenga me ngā kaha rerekē. Ina taupatupatu ēnei tae, ka puta te kikorangi, te magenta, me te kōwhai.
Ka hangaia ngā rama RGB mā te whakakotahi i ngā tae matua e toru hei hanga i tētahi ahua. Hei tāpiri, kei reira anō ngā LED kikorangi me ngā phosphor kōwhai, me ngā LED ultraviolet me ngā phosphor RGB. I te nuinga o te wā, he mātāpono whakaahua ō rāua e rua.
He rite tonu te whāinga o te rama mā LED me te rama RGB LED, ā, e tumanako ana rāua kia rite ki te hua o te rama mā, engari ka whakaatuhia tika tētahi hei rama mā, ā, ka hangaia tētahi mā te whakaranu i te whero, te kakariki me te kikorangi.
