Iyo RGB (Red, Green, Blue) interface inzira inoshandiswa zvakanyanya yekubatanidza uye kutaurirana neLCD skrini, kunyanya yakapararira mumadiki ekuratidzira maapplication. Iyo inodaidzwawo seTTL (Transistor-Transistor Logic), iyi interface inofambisa data inofambirana, ichifambisa kufambiswa kwedata rakawanda panguva imwe chete. Iyi parallel transmission inogonesa kukurumidza kutamisa data zvichienzaniswa neserial nzira dzekutumira.
Iyo RGB interface ine akati wandei mapini echiratidzo, imwe neimwe ichishanda yakanangana nechinangwa:
RESET: Pini iyi inogadzirisa zvakare chiratidziro kune yayo yekutanga, ichibvisa chero data iripo uye ichigadzirira iyo nyowani yekuisa.
HSYNC (Horizontal Sync): Inowiriranisa kuchinjika kutarisisa kwechiratidziro, kuve nechokwadi chekuti mutsara wega wega wemapikiseli akanyatso kurongeka kumufananidzo wakagadzikana.
VSYNC (Vertical Sync): Inowiriranisa iyo yakatwasuka scanning yechiratidziro, ichiva nechokwadi chekuti imwe neimwe column yemapikseli yakanyatso kurongeka kubva kumusoro kusvika pasi.
DOTCLK (Clock): Inopa wachi chiratidzo chinodiwa kuwiriranisa kutapurirana kwedata, kuve nechokwadi chekuti data rinotumirwa panguva dzinoenderana.
DE (Data Inogonesa): Inoratidza kana iyo data iri kutumirwa inoshanda uye inofanirwa kuratidzwa pachiratidziri, nekudaro ichivandudza huchokwadi uye kuderedza zvikanganiso.
RGB Data Lines: Mitsetse iyi inotakura ruzivo rweruvara, ine mitsetse yakaparadzana yetsvuku, yegirinhi, uye yebhuruu, zvichiita kuti sikirini isanganise mavara aya kuti ibudise huwandu hwakazara hwemavara anooneka.
Iyo RGB interface inotsigira akasiyana data mafomati, anosanganisira:
16-bit (RGB565): Inoshandisa 5 bits kune tsvuku, 6 bits yegirinhi, uye 5 bits yebhuruu, inotsigira kusvika 65,536 mavara akasiyana, ichipa chiyero pakati pekudzika kwemavara uye saizi yedata.
18-bit (RGB666): Inoshandisa 6 bits imwe neimwe yetsvuku, yegirinhi, uye yebhuruu, inobvumira 262,144 mavara, ichipa mamwe mavara akadzika uye akapfuma mifananidzo kana ichienzaniswa neiyo 16-bit fomati.
24-bit (RGB888): Inoshandisa 8 bits imwe neimwe kune yakatsvuka, yegirini, uye yebhuruu, inotsigira anosvika 16.7 miriyoni mavara, ichipa yakanyanya kudzika kweruvara uye nemazvo, yakanakira kuratidza yakadzama uye inoyevedza mifananidzo.
Zvakanakira zveRGB interface zvinosanganisira kukurumidza kufambisa data uye kunyora zvakananga kuchiratidziro, izvo zvinoderedza latency uye inosimudzira kukurumidza kwechiratidziro uye kupindura. Nekudaro, zvakare ine zvayakaipira, senge yakakwira chiratidzo voltage, izvo zvinogona kuita kuti iite ruzha uye kukanganiswa kwemagetsi (EMI), uye kudzikisira kune zvidiki zviratidziro nekuda kwekuoma kwekugadzirisa mitsara yedata.
Iyo RGB interface inowana maapplication mumidziyo inoda kukurumidza kugadziridzwa uye nekukurumidza kutumira data, senge madiki mamonitor, dijitari mafoto mafuremu, uye maindasitiri emidziyo. Magadzirirwo ayo akakwana anoita kuti ikwane nzvimbo-zvishandiso zvinomanikidzika, ukuwo kugona kwayo kuratidza mifananidzo nekukurumidza uye zvakatsetseka kunobatsira kumafuremu emifananidzo yedhijitari. Mumichina yemuindasitiri, RGB interface inopa chaiyo-nguva yekuona data, izvo zvakakosha pakudzora mapaneru nemasisitimu ekutarisisa uko kumhanyisa nekurongeka kwakakosha.
