Iscreen seLCD sesona sixhobo sixhaphakileyo sokubonisa kubomi bethu bemihla ngemihla nasemsebenzini.Inokufumaneka kwiikhompyuter, koomabonwakude, kwizixhobo eziphathwayo, kunye nezinye iimveliso zombane ezahlukeneyo.Imodyuli yekristale ye-liquid ayinikezeli kuphela imbonakalo yekhwalithi ephezulu, kodwa inikezela ngolwazi nge-interface yayo ephambili.Eli nqaku liza kugxila kujongano oluphambili kunye nenkcazo yemveliso yeTft Display.
Ujongano oluphambili lweTft Display luphunyezwa ngobuchule bojongano olwahlukeneyo.Ezinye zeetekhnoloji zonxibelelwano oluqhelekileyo ziquka i-RGB, i-LVDS, i-EDP, i-MIPI, i-MCU, kunye ne-SPI.Ezi teknoloji zojongano zidlala indima ephambili kuyilo kunye nokusebenza kwezikrini zeLCD.
I-interface ye-RGB yenye yezona zinto ziqhelekileyo zokubonisa isikrini se-LCD.Yenza imifanekiso kwiipikseli zemibala emithathu: obomvu (R), oluhlaza (G), nobhlowu (B).Ipixel nganye imelwe yindibaniselwano eyahlukileyo yale mibala mithathu isisiseko, ekhokelela kumboniso wombala okumgangatho ophezulu.Ujongano lweRGB luyafumaneka kwiimonitha ezininzi zekhompyuter kunye nezikrini zikamabonwakude.
I-LVDS (i-Low Voltage Differential Signaling) i-interface yiteknoloji ye-interface eqhelekileyo esetyenziselwa i-high-resolution liquid crystal modules.Luphawu olusezantsi lwe-voltage umahluko phakathi kojongano lwetekhnoloji.Indlela yokuhambisa umqondiso wevidiyo yedijithali iphuhliswe ukoyisa iziphene zokusetyenziswa kwamandla aphezulu kunye nokuphazamiseka kombane we-EMI ephezulu xa uhambisa idatha yebroadband ephezulu yenqanaba le-TTL.Ujongano lwemveliso ye-LVDS lisebenzisa i-voltage ephantsi kakhulu (malunga ne-350mV) ukuhambisa ngokwahlukileyo idatha kwiitrayisi ezimbini ze-PCB okanye iperi yeentambo ezilungeleleneyo, oko kukuthi, ukuhanjiswa kophawu lolwahlulo lombane ophantsi.Ukusetyenziswa kojongano lwemveliso ye-LVDS ivumela imiqondiso ukuba idluliselwe kwimigca yePCB eyahlukileyo okanye iintambo ezilungeleleneyo ngesantya samakhulu aliqela Mbit/s.Ngenxa yokusetyenziswa kombane ophantsi kunye neendlela eziphantsi zokuqhuba ngoku, ingxolo ephantsi kunye nokusetyenziswa kwamandla aphantsi kuyafezekiswa.Isetyenziswa ikakhulu ukunyusa isantya sothumelo lwedatha yesikrini kunye nokunciphisa ukuphazamiseka kwe-electromagnetic.Ngokusebenzisa ujongano lwe-LVDS, izikrini ze-LCD zinokusasaza amanani amakhulu edatha ngaxeshanye kwaye zifezekise umgangatho womfanekiso ophezulu.
I-EDP (i-Embedded DisplayPort) i-interface sisizukulwana esitsha seTekhnoloji ye-Tft Display interface yeelaptops kunye neetafile.Ineenzuzo ze-bandwidth ephezulu kunye nezinga eliphezulu lokudlulisa idatha, enokuxhasa isisombululo esiphezulu, izinga eliphezulu lokuhlaziya kunye nokusebenza kombala ocebileyo.Isetyenziswa ikakhulu ukunyusa isantya sothumelo lwedatha yesikrini kunye nokunciphisa ukuphazamiseka kwe-electromagnetic.Ngokusebenzisa ujongano lwe-LVDS, izikrini zeLCD zinokusasaza amanani amakhulu edatha ngaxeshanye kwaye zifezekise umgangatho womfanekiso ophezulu.I-interface ye-EDP yenza ukuba isikrini se-LCD sibe neziphumo ezibonakalayo ezingcono kwizixhobo eziphathwayo.
I-MIPI (i-Mobile Industry Processor Interface) ngumgangatho oqhelekileyo wojongano lwezixhobo eziphathwayo.I-interface ye-MIPI inokudlulisa ividiyo ephezulu kunye nedatha yomfanekiso kunye nokusetyenziswa kwamandla aphantsi kunye ne-bandwidth ephezulu.Isetyenziswa kakhulu kwizikrini zeLCD zezixhobo eziphathwayo ezinjengee-smartphones kunye neetafile.
I-interface ye-MCU (i-Microcontroller Unit) isetyenziselwa ubukhulu becala kwamanye amandla aphantsi, i-low-resolution Tft Displays.Idla ngokusetyenziswa kwizixhobo zombane ezilula ezifana nekhaltyhuleyitha kunye neewotshi ezikrelekrele.I-interface ye-MCU inokulawula ngokufanelekileyo umboniso kunye nemisebenzi yesikrini sokubonisa i-LCD ngelixa usebenzisa amandla aphantsi.Ugqithiso lwebit lwedatha lubandakanya i-8-bit, i-9-bit, i-16-bit kunye ne-18-bit.Udibaniso lwahlulahlulwe: CS/, RS (ukhetho lokubhalisa), i-RD/, i-WR/, kunye nomgca wedatha.Iingenelo zezi: ulawulo olulula nolulula, akukho wotshi kunye nemiqondiso yongqamaniso efunekayo.Ukungalungi kukuba: idla i-GRAM, ngoko ke kunzima ukufezekisa isikrini esikhulu (QVGA okanye ngaphezulu).
I-SPI (i-Serial Peripheral Interface) yitekhnoloji yojongano olulula noluqhelekileyo olusetyenziselwa ukuqhagamshela ezinye iikhompyuter ezincinci, ezinjengeewotshi ezihlakaniphile kunye nezixhobo eziphathwayo.I-interface ye-SPI ibonelela ngezantya ezikhawulezayo kunye nobungakanani bephakheji encinci xa uhambisa idatha.Nangona umgangatho wayo wokubonisa uphantsi, ufanelekile kwezinye izixhobo ezingenazo iimfuno eziphezulu zeziphumo zokubonisa.Ivumela i-MCU kunye nezixhobo ezahlukeneyo ze-peripheral ukuba zinxibelelane ngendlela elandelelanayo ukutshintshiselana ngolwazi.I-SPI ineerejista ezintathu: irejista yokulawula i-SPCR, irejista yesimo se-SPSR kunye nerejista yedatha ye-SPDR.Izixhobo ezijikelezayo ikakhulu zibandakanya isilawuli senethiwekhi, umqhubi weTft Display, iFLASHRAM, iA/D converter kunye neMCU, njl.
Ukushwankathela, ujongano oluphambili lwesikrini sokubonisa i-LCD lugubungela iintlobo ngeentlobo zetekhnoloji ye-interface efana ne-RGB, i-LVDS, i-EDP, i-MIPI, i-MCU kunye ne-SPI.Itekhnoloji yojongano olwahlukileyo lunezicelo ezahlukeneyo kwiiDisplay Tft ezahlukeneyo.Ukuqonda iimpawu kunye nemisebenzi yetekhnoloji yojongano lwescreen seLCD kuya kusinceda ukuba sikhethe iimveliso zemodyuli yekristale elulwelo ezihambelana neemfuno zethu, kwaye sisebenzise ngcono kwaye siqonde umgaqo wokusebenza wezikrini zeLCD.
