Akwai nau'ikan musaya na LCD da yawa, kuma rabe-raben yana da kyau sosai.Ya dogara da yanayin tuƙi da yanayin sarrafawa na LCD.A halin yanzu, akwai nau'ikan haɗin LCD masu launi da yawa akan wayar hannu: Yanayin MCU, yanayin RGB, yanayin SPI, yanayin VSYNC, yanayin MDI, da yanayin DSI.Yanayin MCU (kuma an rubuta shi a yanayin MPU).Tsarin TFT kawai yana da haɗin RGB.Koyaya, aikace-aikacen yafi yanayin MUC da yanayin RGB, bambancin shine kamar haka:
1. MCU interface: Za a canza umarnin, kuma janareta na lokaci zai samar da sigina na lokaci don fitar da direbobin COM da SEG.
RGB dubawa: Lokacin rubuta saitin rajista na LCD, babu bambanci tsakanin ƙirar MCU da ƙirar MCU.Bambancin kawai shine yadda aka rubuta hoton.
2. A cikin yanayin MCU, tun da ana iya adana bayanan a cikin GRAM na ciki na IC sannan a rubuta su zuwa allon, ana iya haɗa wannan yanayin LCD kai tsaye zuwa bas ɗin MEMORY.
Ya bambanta lokacin amfani da yanayin RGB.Ba shi da RAM na ciki.HSYNC, VSYNC, ENABLE, CS, RESET, RS za a iya haɗa kai tsaye zuwa tashar GPIO na MEMORY, kuma ana amfani da tashar GPIO don daidaita yanayin motsi.
3. Yanayin dubawa na MCU: An rubuta bayanan nuni zuwa DDRAM, wanda galibi ana amfani dashi don nunin hoto.
Yanayin dubawa na RGB: bayanan nuni ba a rubuta su zuwa DDRAM, allon rubutu kai tsaye, sauri, galibi ana amfani dashi don nuna bidiyo ko rayarwa.
Yanayin MCU
Domin galibi ana amfani da shi a fannin na'urorin na'ura mai kwakwalwa guda daya, ana sanya masa suna.Ana amfani da shi sosai a cikin wayoyin hannu marasa ƙarfi da matsakaici, kuma babban fasalinsa shine arha.Ma'auni na ƙayyadaddun ƙayyadaddun ƙirar MCU-LCD shine ma'aunin bas na Intel 8080, don haka ana amfani da I80 don komawa zuwa allon MCU-LCD a cikin takardu da yawa.Ana iya raba galibi zuwa yanayin 8080 da yanayin 6800, babban bambanci tsakanin su biyun shine lokaci.Mai watsa bayanai yana da 8-bits, 9-bits, 16-bits, 18-bits, da 24-bits.An raba haɗin zuwa: CS/, RS (zaɓin rajista), RD/, WR/, sannan layin bayanai.Amfanin shine cewa sarrafawa yana da sauƙi kuma mai dacewa, kuma ba a buƙatar agogo da siginar aiki tare.Rashin hasara shine cewa yana biyan GRAM, don haka yana da wahala a cimma babban allo (3.8 ko fiye).Don LCM na MCU dubawa, guntu na ciki ana kiransa direban LCD.Babban aikin shine canza bayanai/umurnin da mai watsa shiri ya aika zuwa bayanan RGB na kowane pixel da nuna shi akan allon.Wannan tsari baya buƙatar maki, layi, ko agogon firam.
Yanayin SPI
An yi amfani da shi ƙasa da ƙasa, akwai layi 3 da layi 4, kuma haɗin haɗin shine CS/, SLK, SDI, SDO guda hudu, haɗin yana da ƙananan amma sarrafa software ya fi rikitarwa.
Yanayin DSI
Wannan yanayin serial bidirectional high-gudun umarnin watsa yanayin, haɗin yana da D0P, D0N, D1P, D1N, CLKP, CLKN.
Yanayin MDI (MobileDisplayDigitalInterface)
MDI na Qualcomm's interface, wanda aka gabatar a cikin 2004, yana inganta amincin wayar hannu kuma yana rage yawan amfani da wutar lantarki ta hanyar rage wayoyi, wanda zai maye gurbin yanayin SPI kuma ya zama babban hanyar sadarwa mai sauri don wayar hannu.Haɗin shine galibi host_data, host_strobe, client_data, client_strobe, power, GND.
Yanayin RGB
Babban allon yana amfani da ƙarin hanyoyi, kuma watsa bayanan bit yana da 6-bits, 16-bits da 18-bits, da 24-bits.Haɗin kai gabaɗaya sun haɗa da: VSYNC, HSYNC, DOTCLK, CS, RESET, wasu kuma suna buƙatar RS, sauran kuma shine layin bayanai.Amfaninsa da rashin amfanin sa daidai suke da yanayin MCU.
