RGB (Red, Green, Blue) matut mahkai lam gaw LCD screen ni hte matut mahkai na matu hte matut mahkai na matu grai lang ai ladat langai rai nga ai, grau nna kaji ai display application ni hta grau law ai. TTL (Transistor{-Transistor Logic) ngu nna mung tsun ai, ndai interface gaw parallel hku nna data ni hpe htawt sit ya ai, data law law hpe kalang ta htawt sit ai lam hpe loi ai hku galaw ya ai. Ndai parallel transmission gaw serial transmission ladat ni hte shingdaw yang grau lawan ai data htawt sit ai lam hpe galaw ya lu ai.
RGB interface hta signal pin law law lawm nna, langai hte langai gaw yaw shada lam langai hpe daw jau ai:
RESET: Ndai pin gaw, dai display hpe shi a shawng nnan na masa de bai gram lajang ya ai, ya nga ai data ni hpe clear galaw nna, input nnan ni a matu hkyen lajang ya ai.
HSYNC (Horizontal Sync): Synchronize galaw ai gaw, display a horizontal scanning hpe, pixel langai hpra hpe ngang grin ai sumla a matu hkrak hkrak hkrak hkra galaw da ai.
VSYNC (Vertical Sync): Synchronize galaw ai gaw, display a vertical scanning hpe, pixel ni a column langai hpra hpe ntsa kaw nna lawu du hkra hkrak hkra hkrak hkra galaw da ai.
DOTCLK (Clock): Data hpe garan gachyan na matu ra ai ahkying masat hpe jaw ya ai, data hpe n galai shai ai aten ni hta sa ya ai hpe kam hpa ai.
DE (Da Reable): Gara aten hta sa dat ai hpe madun nna, screen ntsa kaw madun ra ai, dai hku nna hkrak ai lam hpe grau kaja hkra galaw nna, shut ai lam ni hpe shayawm ya lu ai.
RGB Data Lines: Ndai line ni gaw nsam hte seng ai shiga ni hpe gun hpai nna, hpraw, hpraw, hpraw ni a matu garan nna ka da ai, screen hpe kayau kaya galaw nna, mu lu ai nsam ni a hkum tsup ai spectrum hpe shapraw lu na matu galaw ya ai.
RGB interface gaw data format amyu myu hpe madi shadaw ya ai, dai ni hta:
16-bit (RGB565): Hpun hpraw a matu 5 bits, hpraw a matu 6 bits, blue a matu 5 bits hpe jai lang nna, nsam amyu myu 65,536 du hkra madi shadaw ya ai, nsam sung ai hte data size lapran hta rap ra ai lam hpe jaw ya ai.
18-bit (RGB666): Hpraw, hpraw, hpraw ni a matu langai hpra hpe 6 bits galaw ya ai, 262,144 hpe jaw ya ai, 16-bit format hte shingdaw yang grau nna nsam sung ai hte grau sut su ai sumla ni hpe jaw ya ai.
24-bit (RGB888): Hpraw, hpraw, hte hpraw ai ni a matu langai hpra 8 bits lang nna, nsam wan 16.7 du hkra madi shadaw ya ai, nsam sung ai hte hkrak ai lam grau tsaw ai hpe jaw ya ai, hkrang sumla ni hpe hkrak hkrak hte n-gun ja ai sumla ni hpe madun na matu grai kaja ai.
RGB interface a akyu ni gaw, lawan ai data transmission hte screen de direct ka ai lam ni lawm ai, dai gaw latency hpe shayawm kau ya nna, display a lawan ai hte mahtai jaw ai lam hpe grau kaja hkra galaw ya ai. Raitim, shi hta n kaja ai lam ni mung nga ai, n kaja ai lam ni mung nga ai, dai gaw signal voltage grai law ai, dai gaw nsen hte electromagnetic shingjawng ai lam (EMI), parallel data lines ni hpe hparan ai lam hta yak hkak ai majaw, kaji ai display ni hpe shadawn sharam tawn da ai.
RGB interface gaw, lawan ai hku gram lajang ra ai jak ni hte lawan ai data ni hpe shalai ya ra ai device ni hta application ni hpe mu lu ai, dai ni gaw, monitor kaji ni, digital sumla hkrung ni, hte bungli galaw ai arung arai ni zawn re ai ni hpe mu lu ai. Shi a compact design gaw shara- n-gun rawng ai jak ni a matu htuk manu ai, sumla ni hpe lawan ai hte hkrak hkra madun dan lu ai atsam gaw digital sumla hkrung ni a matu akyu rawng ai. Industrial arung arai ni hta, RGB interface gaw tengman ai- aten na jahpan ni hpe jaw ya ai, dai gaw hkang zing ai panel ni hte yu reng ai ladat ni a matu ahkyak ai shara ni hta ahkyak ai shara ni hta ahkyak nga ai.
