Gane hasken RGB naFatar Analyzer
An tsara RGB daga ka'idar haske mai launi. A cikin ma'anar layman, hanyar haɗa launin launi kamar ja, kore, da shuɗi. Lokacin da fitilunsu suka yi karo da juna, launukan suna gaurayawa, amma hasken yana daidai da Jimillar hasken biyun, da yawan gauraye mafi girma, wato additive mixing.
Ga superposition na ja, kore da shuɗi fitilu, mafi haske superposition yankin na tsakiyar uku launuka ne fari, da kuma halaye na ƙari hadawa: da mafi superposition, da haske.
Kowace tashoshi masu launi uku, ja, kore, da shuɗi, an raba su zuwa matakan haske 256. A 0, "haske" shine mafi rauni - an kashe shi, kuma a 255, "haske" shine mafi haske. Lokacin da ma'aunin launin toka masu launi uku suka zama iri ɗaya, ana haifar da sautin launin toka mai launin toka daban-daban, wato idan launin toka mai launi uku ya zama 0, to shine mafi duhun sautin baki; lokacin da launin toka mai launi uku ya kasance 255, shine mafi kyawun sautin farin .
Ana kiran launukan RGB masu ƙari saboda ka ƙirƙiri fari ta hanyar haɗa R, G, da B tare (wato, duk hasken yana haskakawa a ido). Ana amfani da launuka masu ƙari a cikin hasken wuta, talabijin da na'urorin kwamfuta. Misali, nuni yana samar da launi ta hanyar fitar da haske daga ja, kore, da shuɗi phosphor. Mafi rinjayen bakan da ake iya gani ana iya wakilta su azaman cakuda ja, kore, da shuɗi (RGB) haske cikin mabanbantan ma'auni da ƙarfi. Lokacin da waɗannan launuka suka mamaye, ana samar da cyan, magenta, da rawaya.
Ana samar da fitilun RGB ta launuka na farko guda uku da aka haɗa don samar da hoto. Bugu da kari, akwai kuma shudiyan ledoji masu rawaya phosphor, da ultraviolet LEDs tare da RGB phosphor. Gabaɗaya magana, dukansu biyu suna da ƙa'idodinsu na hoto.
Dukansu farin haske LED da RGB LED suna da manufa ɗaya, kuma dukkansu suna fatan cimma tasirin farin haske, amma ɗayan ana gabatar da shi azaman farin haske, ɗayan kuma yana samuwa ta hanyar haɗa ja, kore da shuɗi.
