Isikrini sokubonisa se-LCD siyidivayisi yokubonisa evame kakhulu empilweni yethu yansuku zonke nasemsebenzini.Ingatholakala kumakhompuyutha, kumathelevishini, kumaselula, nakweminye imikhiqizo ehlukahlukene kagesi.Imojula ye-crystal ye-liquid ayinikezi kuphela imiphumela yokubukwa kwekhwalithi ephezulu, kodwa futhi inikeza ulwazi ngokusebenzisa isikhombimsebenzisi sayo esiyinhloko.Lesi sihloko sizogxila kusixhumi esibonakalayo esiyinhloko kanye nencazelo yomkhiqizo we-Tft Display.
I-interface eyinhloko ye-Tft Display isetshenziswa ngobuchwepheshe obuhlukahlukene bokusebenza.Obunye ubuchwepheshe obujwayelekile bokusebenzisana buhlanganisa i-RGB, i-LVDS, i-EDP, i-MIPI, i-MCU, ne-SPI.Lobu buchwepheshe bokusebenza budlala indima ebalulekile ekwakhiweni nasekusebenzeni kwezikrini ze-LCD.
I-interface ye-RGB ingenye yezindlela ezivame kakhulu zokubonisa isikrini se-LCD.Idala izithombe ngamaphikseli emibala emithathu: obomvu (R), oluhlaza okotshani (G), noluhlaza okwesibhakabhaka (B).Iphikseli ngalinye limelelwa inhlanganisela ehlukile yale mibala emithathu eyisisekelo, okuholela ekubonisweni kombala wekhwalithi ephezulu.I-interface ye-RGB iyatholakala kumamonitha amaningi wendabuko wekhompyutha nezikrini zethelevishini.
Isixhumi esibonakalayo se-LVDS (Low Voltage Differential Signaling) siwubuchwepheshe besixhumi esibonakalayo obuvamile obusetshenziselwa amamojula ekristalu ewuketshezi anokulungiswa okuphezulu.Kuyisixhumi esibonakalayo sobuchwepheshe besignali esine-voltage ephansi.Indlela yokudlulisa isignali yevidiyo yedijithali ithuthukiswe ukuze inqobe ukushiyeka kokusetshenziswa kwamandla aphezulu kanye nokuphazamiseka kukagesi okuphakeme kwe-EMI lapho kuthunyelwa idatha ye-broadband high bit rate ezingeni le-TTL.Isixhumi esibonakalayo se-LVDS sisebenzisa i-voltage ephansi kakhulu (cishe i-350mV) ukuze idlulise idatha ngokuhlukile kumathrekhi amabili e-PCB noma izintambo ezilinganayo, okungukuthi, ukudluliswa kwesignali ehlukile yamandla aphansi.Ukusetshenziswa kwesixhumi esibonakalayo se-LVDS kuvumela amasiginali ukuthi adluliselwe emigqeni ehlukile ye-PCB noma izintambo ezilinganiselayo ngenani elingamakhulu ambalwa Mbit/s.Ngenxa yokusetshenziswa kwamandla kagesi aphansi kanye nezindlela zokushayela zamanje eziphansi, umsindo ophansi kanye nokusetshenziswa kwamandla okuphansi kufinyelelwa.Isetshenziswa kakhulu ukukhulisa isivinini sokudluliswa kwedatha kwesikrini nokunciphisa ukuphazamiseka kwe-electromagnetic.Ngokusebenzisa isixhumi esibonakalayo se-LVDS, izikrini ze-LCD zingadlulisela inani elikhulu ledatha ngesikhathi esisodwa futhi zithole ikhwalithi yesithombe ephezulu.
Isixhumi esibonakalayo se-EDP (Embedded DisplayPort) isizukulwane esisha sobuchwepheshe besixhumi esibonakalayo se-Tft Display kumakhompyutha aphathekayo namathebulethi.Inezinzuzo zomkhawulokudonsa ophezulu kanye nezinga eliphezulu lokudlulisa idatha, elingasekela ukulungiswa okuphezulu, izinga eliphezulu lokuvuselela kanye nokusebenza kombala okucebile.Isetshenziswa kakhulu ukukhulisa isivinini sokudluliswa kwedatha kwesikrini nokunciphisa ukuphazamiseka kwe-electromagnetic.Ngokusebenzisa isixhumi esibonakalayo se-LVDS, izikrini ze-LCD zingadlulisela inani elikhulu ledatha ngesikhathi esisodwa futhi zithole ikhwalithi ephezulu yesithombe.I-interface ye-EDP yenza isikrini sokubonisa se-LCD sibe nemiphumela engcono yokubonwa kumadivayisi eselula.
I-MIPI (I-Mobile Industry Processor Interface) iyindinganiso evamile yesixhumi esibonakalayo samadivayisi eselula.I-interface ye-MIPI ingadlulisela idatha yevidiyo nesithombe sekhwalithi ephezulu ngokusetshenziswa kwamandla okuphansi kanye nomkhawulokudonsa ophezulu.Isetshenziswa kakhulu kuzikrini ze-LCD zamadivayisi eselula njengama-smartphone namathebulethi.
Isixhumi esibonakalayo se-MCU (I-Microcontroller Unit) sisetshenziselwa ikakhulukazi izibonisi ze-Tft ezinamandla aphansi, ezinokulungiswa okuphansi.Ivamise ukusetshenziswa ezintweni ezilula zikagesi njengezibali namawashi ahlakaniphile.I-interface ye-MCU ingalawula ngempumelelo isibonisi kanye nemisebenzi yesikrini sokubonisa se-LCD kuyilapho isebenzisa amandla aphansi.Ukudluliswa kwe-data bit kuhlanganisa i-8-bit, 9-bit, 16-bit kanye ne-18-bit.Ukuxhumana kuhlukaniswe: CS/, RS (okukhethwa kukho kokubhalisa), RD/, WR/, bese kuba ulayini wedatha.Izinzuzo yilezi: isilawuli esilula nesikahle, alikho iwashi namasignali okuvumelanisa adingekayo.Ububi buwukuthi: idla i-GRAM, ngakho-ke kunzima ukuzuza isikrini esikhulu (i-QVGA noma ngaphezulu).
I-SPI (i-Serial Peripheral Interface) iwubuchwepheshe be-interface obulula futhi obuvamile obusetshenziselwa ukuxhuma amakhompyutha athile amancane, njengamawashi ahlakaniphile namadivayisi aphathwayo.I-interface ye-SPI ihlinzeka ngesivinini esisheshayo nosayizi wephakheji omncane lapho uthumela idatha.Nakuba ikhwalithi yayo yokubonisa iphansi ngokuqhathaniswa, ifaneleka kwamanye amadivayisi angenazo izimfuneko eziphezulu zemiphumela yokubonisa.Inika amandla i-MCU kanye namadivayisi ahlukahlukene asendaweni ukuxhumana ngendlela ye-serial ukushintshanisa ulwazi.I-SPI inamarejista amathathu: irejista yokulawula i-SPCR, irejista yesimo i-SPSR kanye nerejista yedatha ye-SPDR.Imishini ezungezayo ihlanganisa ikakhulukazi isilawuli senethiwekhi, umshayeli we-Tft Display, i-FLASHRAM, i-A/D converter ne-MCU, njll.
Ukufingqa, isixhumi esibonakalayo esiyinhloko sesikrini sokubonisa se-LCD sihlanganisa ubuchwepheshe obuhlukahlukene bokusebenzisana obufana ne-RGB, i-LVDS, i-EDP, i-MIPI, i-MCU ne-SPI.Ubuchwepheshe be-interface obuhlukile bunezinhlelo zokusebenza ezihlukene kuma-Tft Displays ahlukene.Ukuqonda izici nemisebenzi yobuchwepheshe bokusebenzelana kwesikrini se-LCD kuzosisiza sikhethe imikhiqizo yemojuli yekristalu ewuketshezi efanelana nezidingo zethu, futhi sisebenzise futhi siqonde kangcono isimiso sokusebenza sezikrini ze-LCD.
