Qaphela ukukhanya kwe-RGB kweIsihlalutyi solusu

I-RGB yenzelwe umgaqo wokukhanya kombala. Ngokwendlela eqhelekileyo, indlela yayo yokudibanisa imibala ifana nezibane ezibomvu, eziluhlaza, neziluhlaza okwesibhakabhaka. Xa izibane zazo zigqithana, imibala iyaxutywa, kodwa ukukhanya kuyalingana. Isimbuku sokukhanya kwezi zimbini, kokukhona kuxutywa ngakumbi kokukhona ukukhanya kuphezulu, oko kukuthi, ukuxuba okongeziweyo.

Kwi-superposition yezibane ezibomvu, eziluhlaza neziluhlaza okwesibhakabhaka, indawo eqaqambileyo ye-superposition yemibala emithathu ephakathi imhlophe, kwaye iimpawu zokuxuba ezongeziweyo: okukhona i-superposition ingaphezulu, kokukhona ikhanya ngakumbi.

Itshaneli nganye yemibala emithathu, ebomvu, eluhlaza, nebhlowu, yahlulwe yangamanqanaba angama-256 okukhanya. Kwi-0, "ukukhanya" yeyona ibuthathaka - icinyiwe, kwaye kwi-255, "ukukhanya" yeyona ikhanyayo. Xa amaxabiso e-grayscale enemibala emithathu afana, kuveliswa iithoni ezingwevu ezinexabiso elihlukileyo le-grayscale, oko kukuthi, xa i-grayscale enemibala emithathu ingu-0 yonke, iba yithoni emnyama emnyama; xa i-grayscale enemibala emithathu ingu-255, iba yithoni emhlophe eqaqambileyo.

Imibala ye-RGB ibizwa ngokuba yimibala eyongeziweyo kuba wenza umhlophe ngokudibanisa u-R, u-G, kunye no-B kunye (oko kukuthi, lonke ukukhanya kubonakaliswa kwakhona emehlweni). Imibala eyongeziweyo isetyenziswa ekukhanyiseni, kumabonakude nakwiimonitha zekhompyutha. Umzekelo, izibonisi zivelisa umbala ngokukhupha ukukhanya kwi-phosphors ebomvu, eluhlaza, nebhlowu. Uninzi olukhulu lwe-spectrum ebonakalayo lunokubonakaliswa njengomxube wokukhanya okubomvu, okuluhlaza, kunye nobhlowu (RGB) ngobuninzi kunye namandla ahlukeneyo. Xa le mibala idibana, kuvela i-cyan, i-magenta, kunye nomthubi.

Izibane ze-RGB zenziwe ngemibala emithathu ephambili edityanisiweyo ukwenza umfanekiso. Ukongeza, kukwakho nee-LED eziluhlaza okwesibhakabhaka ezine-phosphors etyheli, kunye nee-LED ze-ultraviolet ezine-phosphors ze-RGB. Ngokubanzi, zombini zinemigaqo yazo yokufota.

Zombini i-LED emhlophe kunye ne-RGB LED zinenjongo efanayo, kwaye zombini zinethemba lokufezekisa isiphumo sokukhanya okumhlophe, kodwa enye ivezwa ngqo njengokukhanya okumhlophe, kwaye enye yenziwa ngokuxuba obomvu, oluhlaza kunye noluhlaza okwesibhakabhaka.
