I-interface ye-RGB (eBomvu, eluhlaza, eluhlaza okwesibhakabhaka) yindlela esetyenziswa ngokubanzi yokudibanisa kunye nokunxibelelana nezikrini ze-LCD, ngokukodwa zixhaphake kwiinkqubo zokubonisa ezincinci. Ikwabizwa ngokuba yi-TTL (i-Transistor{1}}i-Transistor Logic), olu jongano luthumela idatha ngokunxuseneyo, luququzelela ukudluliselwa ngaxeshanye kwamasuntswana amaninzi edatha. Olu dluliselo oluhambelanayo lwenza amaxabiso okudluliselwa kwedatha ngokukhawuleza xa kuthelekiswa neendlela zothumelo lwe-serial.
I-interface ye-RGB inezikhonkwane ezininzi zesignali, nganye isebenzela injongo ethile:
SETSHENZISWA KHONA: Esi sikhonkwane siseta kwakhona isiboniso kwisimo saso sokuqala, sicoca nayiphi na idatha ekhoyo kwaye siyilungiselele igalelo elitsha.
HSYNC (Ungqamaniso oluthe tye): Ingqamanisa ukuskena okuthe tye komboniso, iqinisekisa ukuba umqolo ngamnye weepixels ulungelelaniswe ngokuchanekileyo kumfanekiso ozinzileyo.
I-VSYNC (Ungqamaniso oluthe nkqo): Ingqamanisa ukuskena okuthe nkqo komboniso, iqinisekisa ukuba ikholamu nganye yeepikseli ilungelelaniswe ngokuchanekileyo ukusuka phezulu ukuya ezantsi.
I-DOTCLK (Ikloko): Ibonelela ngesignali yewotshi eyimfuneko ukuvumelanisa ukuhanjiswa kwedatha, iqinisekisa ukuba idatha ithunyelwa ngezithuba ezihambelanayo.
DE (Vumela idatha): Ibonisa xa idatha ethunyelwayo isemthethweni kwaye kufuneka iboniswe kwisikrini, ngaloo ndlela iphucula ukuchaneka kunye nokunciphisa iimpazamo.
Imigca yedatha yeRGB: Le migca iphethe ulwazi lombala, enemigca eyahlukileyo ebomvu, eluhlaza, nebhlowu, ivumela isikrini ukuxuba le mibala ukuvelisa imibala epheleleyo ebonakalayo.
Ujongano lweRGB luxhasa iifomathi ezahlukeneyo zedatha, kubandakanya:
I-16-bit (RGB565): Isebenzisa i-5 bits kubomvu, i-6 bits eluhlaza, kunye ne-5 bits eluhlaza okwesibhakabhaka, ixhasa ukuya kuthi ga kwi-65,536 imibala eyahlukeneyo, inika ibhalansi phakathi kobunzulu bombala kunye nobukhulu bedatha.
I-18-bit (RGB666): Iqeshe 6 bits nganye ebomvu, eluhlaza, kunye blue, ivumela 262,144 imibala, ukunika ubunzulu umbala ngakumbi kunye nemifanekiso etyebileyo xa kuthelekiswa ifomathi 16-bit.
24-bit (RGB888): Isebenzisa iibhithi ezisi-8 nganye kubomvu, eluhlaza, naluhlaza, ixhasa ukuya kuthi ga kwi-16.7 yezigidi zemibala, inika obona mbala ubunzulu kunye nokuchaneka, ilungele ukubonisa imifanekiso eneenkcukacha kunye nedlamkileyo.
Iinzuzo ze-interface ye-RGB ziquka ukuhanjiswa kwedatha ngokukhawuleza kunye nokubhala ngokuthe ngqo kwisikrini, esinciphisa i-latency kunye nokwandisa isantya somboniso kunye nokuphendula. Nangona kunjalo, ikwanazo izinto ezingeloncedo, ezinje ngevolthi ephezulu yesiginali, enokuthi iyenze ibe lula kwingxolo kunye nokuphazamiseka kwe-electromagnetic interference (EMI), kunye nokuthintelwa kwayo kwimiboniso emincinci ngenxa yobunzima bokulawula imigca yedatha ehambelanayo.
I-interface ye-RGB ifumana izicelo kwizixhobo ezifuna uhlaziyo olukhawulezayo kunye nokuhanjiswa kwedatha ngokukhawuleza, njengeemonitha ezincinci, iifreyimu zeefoto zedijithali, kunye nezixhobo zoshishino. Uyilo lwayo olubambene luyenza ilungele indawo{1}}izixhobo ezithintelweyo, ngelixa ukukwazi kwayo ukubonisa imifanekiso ngokukhawuleza nangokutyibilikayo kuluncedo kwizakhelo zeefoto zedijithali. Kwizixhobo zemizi-mveliso, i-interface ye-RGB ibonelela nge{3}}ixesha lokwenyani lokubonwa kwedatha, eyimfuneko kwiiphaneli zolawulo kunye neenkqubo zokubeka iliso apho isantya kunye nokuchaneka kubalulekile.
