Kunezinhlobo eziningi zokusebenzelana kwe-LCD, futhi ukuhlukaniswa kuhle kakhulu.Ikakhulukazi kuncike kwimodi yokushayela kanye nemodi yokulawula ye-LCD.Njengamanje, kunezinhlobo ezimbalwa zokuxhuma kwe-LCD ngombala kumakhalekhukhwini: Imodi ye-MCU, imodi ye-RGB, imodi ye-SPI, imodi ye-VSYNC, imodi ye-MDDI, nemodi ye-DSI.Imodi ye-MCU (futhi ibhalwe ngemodi ye-MPU).Imojula ye-TFT kuphela ene-interface ye-RGB.Kodwa-ke, uhlelo lokusebenza luyimodi ye-MUC nemodi ye-RGB, umehluko umi kanje:
1. I-interface ye-MCU: Umyalo uzochazwa, futhi ijeneretha yesikhathi izokhiqiza izimpawu zesikhathi ukushayela abashayeli be-COM kanye ne-SEG.
Isixhumi esibonakalayo se-RGB: Lapho ubhala ukulungiselelwa kwerejista ye-LCD, awukho umehluko phakathi kwesixhumi esibonakalayo se-MCU nesixhumi esibonakalayo se-MCU.Umehluko kuphela indlela isithombe esibhalwe ngayo.
2. Kumodi ye-MCU, njengoba idatha ingagcinwa ku-GRAM yangaphakathi ye-IC bese ibhalwa esikrinini, le modi ye-LCD ingaxhunywa ngokuqondile ebhasini le-MEMORY.
Kuhlukile uma usebenzisa imodi ye-RGB.Ayinayo i-RAM yangaphakathi.I-HSYNC, VSYNC, ENABLE, CS, RESET, RS ingaxhunywa ngokuqondile embobeni ye-GPIO ye-MEMORY, futhi imbobo ye-GPIO isetshenziselwa ukulingisa i-waveform.
3. Imodi yokusebenzelana ye-MCU: Idatha yokubonisa ibhalelwe i-DDRAM, evame ukusetshenziselwa ukubonisa isithombe esimile.
Imodi yokusebenzelana ye-RGB: idatha yokubonisa ayibhalwanga ku-DDRAM, isikrini sokubhala esiqondile, esisheshayo, esivame ukusetshenziselwa ukubonisa ividiyo noma ukugqwayiza.
Imodi ye-MCU
Ngenxa yokuthi isetshenziswa kakhulu emkhakheni we-single-chip microcomputers, iqanjwe ngayo.Isetshenziswa kakhulu kumaselula asezingeni eliphansi naphakathi nendawo, futhi isici sayo esiyinhloko ukuthi ishibhile.Itemu elijwayelekile lesixhumi esibonakalayo se-MCU-LCD lingamabhasi e-Intel's 8080, ngakho-ke i-I80 isetshenziselwa ukubhekisa kusikrini se-MCU-LCD emibhalweni eminingi.Ikakhulukazi ingahlukaniswa ngemodi ye-8080 nemodi ye-6800, umehluko omkhulu phakathi kwalokhu kokubili isikhathi.I-data bit transmission inamabhithi angu-8, angu-9, angu-16, angu-18, nama-24.Uxhumano luhlukaniswe: CS/, RS (okukhethwa kukho kokubhalisa), RD/, WR/, bese kuba ulayini wedatha.Inzuzo ukuthi ukulawula kulula futhi kulula, futhi azikho iwashi namasignali okuvumelanisa adingekayo.Okubi ukuthi kubiza i-GRAM, ngakho-ke kunzima ukuzuza isikrini esikhulu (3.8 noma ngaphezulu).Ku-LCM yesixhumi esibonakalayo se-MCU, i-chip yangaphakathi ibizwa ngokuthi umshayeli we-LCD.Umsebenzi oyinhloko ukuguqula idatha/umyalo othunyelwe umsingathi ube idatha ye-RGB yephikseli ngayinye bese uyibonisa esikrinini.Le nqubo ayidingi iphuzu, umugqa, noma amawashi ozimele.
Imodi ye-SPI
Isetshenziswa kancane, kukhona imigqa emi-3 nemigqa engu-4, futhi uxhumano yi-CS/, SLK, SDI, SDO imigqa emine, uxhumano luncane kodwa ukulawula isofthiwe kuyinkimbinkimbi.
Imodi ye-DSI
Le modi ye-serial bidirectional high-speed command transmission mode, uxhumano lune-D0P, D0N, D1P, D1N, CLKP, CLKN.
Imodi ye-MDDI (MobileDisplayDigitalInterface)
I-interface ye-Qualcomm ye-MDDI, eyethulwa ngo-2004, ithuthukisa ukwethembeka komakhalekhukhwini futhi inciphisa ukusetshenziswa kwamandla ngokunciphisa izintambo, okuzothatha indawo yemodi ye-SPI futhi ibe isixhumi esibonakalayo esinesivinini esikhulu seselula.Uxhumo ngokuyinhloko luyidatha_yokusingatha, i-host_strobe, idatha_yeklayenti, i-client_strobe, amandla, i-GND.
Imodi ye-RGB
Isikrini esikhulu sisebenzisa izindlela eziningi, futhi ukudluliswa kwe-data bit nakho kunamabhithi angu-6, amabhithi angu-16 namabhithi angu-18, namabhithi angu-24.Uxhumano ngokuvamile luhlanganisa: I-VSYNC, i-HSYNC, i-DOTCLK, i-CS, i-RESET, kanti okunye futhi kudinga i-RS, kanti okunye ulayini wedatha.Izinzuzo zayo kanye nokubi kuphambene ncamashi nemodi ye-MCU.
