I-interface ye-RGB (Red, Green, Blue) iyindlela esetshenziswa kakhulu yokuxhuma kanye nokuxhumana nezikrini ze-LCD, ezivame kakhulu ezinhlelweni zokubonisa ezincane. Futhi kubizwa ngokuthi i-TTL (Transistor-Transistor Logic), lesi sixhumi esibonakalayo sidlulisela idatha ngokufana, esiza ukudluliswa kanyekanye kwamabhithi amaningi edatha. Lokhu kudluliswa okuhambisanayo kwenza amazinga okudlulisa idatha asheshe uma kuqhathaniswa nezindlela zokudlulisa idatha.
I-interface ye-RGB iqukethe izikhonkwane zesignali ezimbalwa, ngalinye lisebenzisa injongo ethile:
SETHA KABUSHA: Le phinikhodi isetha kabusha isibonisi esimweni saso sokuqala, isula noma iyiphi idatha ekhona futhi isilungiselela okokufaka okusha.
I-HSYNC (Ukuvumelanisa Okuvundlile): Ivumelanisa ukuskena okuvundlile kwesibonisi, iqinisekisa ukuthi umugqa ngamunye wamaphikseli uqondaniswe kahle ukuze uthole isithombe esizinzile.
I-VSYNC (Ukuvumelanisa Okuqondile): Ivumelanisa ukuskena okuqondile kwesibonisi, iqinisekisa ukuthi ikholomu ngayinye yamaphikseli iqondaniswe kahle ukusuka phezulu kuye phansi.
I-DOTCLK (Iwashi): Ihlinzeka ngesignali yewashi edingekayo ukuze uvumelanise ukudluliswa kwedatha, iqinisekisa ukuthi idatha ithunyelwa ngezikhathi ezingaguquki.
I-DE (Vumela Idatha): Ibonisa ukuthi idatha ethunyelwayo isebenza nini futhi kufanele iboniswe esikrinini, ngaleyo ndlela ithuthukise ukunemba nokunciphisa amaphutha.
Imigqa Yedatha ye-RGB: Le migqa iphethe imininingwane yombala, enemigqa ehlukene yokubomvu, okuluhlaza okotshani, nokuluhlaza okwesibhakabhaka, okuvumela isikrini sihlanganise le mibala ukuze sikhiqize i-spectrum egcwele yemibala ebonakalayo.
I-interface ye-RGB isekela amafomethi wedatha ahlukahlukene, okuhlanganisa:
I-16-bit (RGB565): Isebenzisa amabhithi angu-5 kokubomvu, amabhithi angu-6 kokuluhlaza, namabhithi angu-5 kokuluhlaza okwesibhakabhaka, isekela imibala ehlukene engafika ku-65,536, enikeza ibhalansi phakathi kokujula kombala nosayizi wedatha.
I-18-bit (RGB666): Iqasha amabhithi angu-6 ngalinye kokubomvu, okuluhlaza okotshani, nokuluhlaza okwesibhakabhaka, okuvumela imibala engu-262,144, inikeze ukujula kombala okwengeziwe nezithombe ezicebile uma kuqhathaniswa nefomethi ye-16-bit.
24-bit (RGB888): Isebenzisa amabhithi angu-8 ngakunye kokubomvu, okuluhlaza okotshani, nokuluhlaza okwesibhakabhaka, isekela imibala efika ezigidini ezingu-16.7, enikeza ukujula kombala okuphezulu nokunemba, okulungele ukubonisa izithombe ezinemininingwane nezinempilo.
Izinzuzo zesixhumi esibonakalayo se-RGB zifaka phakathi ukudluliswa kwedatha okusheshayo nokubhala okuqondile esikrinini, okunciphisa ukubambezeleka futhi kuthuthukise isivinini sesibonisi nokuphendula. Kodwa-ke, iphinde ibe nokubi, okufana ne-voltage yesiginali ephezulu, engayenza ibe lula kumsindo nokuphazanyiswa kukagesi kagesi (EMI), kanye nomkhawulo wayo kuzibonisi ezincane ngenxa yobunkimbinkimbi bokuphatha imigqa yedatha efanayo.
I-interface ye-RGB ithola izinhlelo zokusebenza kumadivayisi adinga ukubuyekezwa okusheshayo nokudluliswa kwedatha okusheshayo, njengeziqaphi ezincane, amafreyimu ezithombe zedijithali, nemishini yezimboni. Idizayini yayo ehlangene iyenza ifanele isikhala-kumadivayisi abambekayo, kuyilapho ikhono layo lokubonisa izithombe ngokushesha nangokushelela lizuzisa ozimele bezithombe zedijithali. Ezisetshenziswa zezimboni, ukusebenzelana kwe-RGB kunikeza{3}}ukubukwa kwedatha yesikhathi sangempela, okubalulekile kumaphaneli okulawula namasistimu okuqapha lapho isivinini nokunemba kubalulekile.
