Umqondiso we-TTL ngumqondiso oqhelekileyo onokuthi i-TFT-LCD ikwazi ukuqaphela, kunye ne-LVDS TMDS esetyenziswe kamva ifakwe ngekhowudi kwisiseko sayo.Umgca wesignali we-TTL unenani elipheleleyo le-22 (encinci, engabalwanga kunye namandla) eyahlulwe kwi-RGB ye-tri-color signal, ezimbini ze-HS VS isignali yokuvumelanisa intsimi, enye idatha yenza isignali ye-DE isignali yewashi ye-CLK, apho i-RGG yombala wesiseko sesithathu ihluke ngokutsho. kwinani lamasuntswana ekhusi, kunye nemigca yedatha eyahlukeneyo (iisuntswana ezi-6, kunye nenqaku le-8-bit) i-6-bit yesikrini kunye ne-8-bit screen-tri-umbala yi-R0-R5 (R7) G0-G5 (G7) B0- I-B5 (B7) uphawu lwe-tricolor luphawu lombala, ukungahambi kakuhle kuya kwenza ukuba isikrini sibonise ukuphazamiseka kombala.
Ezinye iimpawu ze-4 (i-HS VS DE CLK) ziyimpawu zokulawula, kwaye ukudibanisa kakubi kuya kwenza ukuba amanqaku esikrini angabonakali kwaye angabonakali kakuhle.Ngenxa yokuba inqanaba lesiginali ye-TTL limalunga ne-3V, linempembelelo enkulu ekuhanjisweni komgama omde wezinga eliphezulu, kwaye ukuchasana nokuphazamiseka kubi.Ke ngoko kukho isikrini sojongano lwe-LVDS, okoko nje i-XGA ingaphezulu komyinge wesisombululo sesikrini isebenzisa imo ye-LVDS.
I-LVDS iphinde yahlulwe ibe ngamajelo angatshatanga, amajelo amabini, amasuntswana angama-6, amasuntswana angama-8, amaqhezu, umgaqo kunye necandelo le-TTL liyafana.I-LVDS (uphawu olusezantsi loxinzelelo oluphantsi) lusebenza ngokusebenzisa i-IC ezinikeleyo ukufakela igalelo leleta ye-TTL kwisiginali ye-LVDS, iibhithi ezi-6 njengezahlulo ezi-4, iibhithi ezi-8 zokwahluka kwe-5, amagama omgca wedatha d0-D0-D1-D2-CK- CK-Ck-Ukuba yi-6-bit screen, akukho D3 - I-D3 kunye nesethi yeempawu, ezifakwe kwikhowudi kwibhodi yethu yekhompyutha.Ngakolunye uhlangothi lwesikrini, kukho kwakhona i-IC yokubhala kunye nomsebenzi ofanayo, ukuguqula isignali ye-LVDS ibe yisignali ye-TTL, kwaye isikrini siphela ngesignali ye-TTL, kuba inqanaba lesignali ye-LVDS malunga ne-1V, kunye nokuphazamiseka phakathi imigca kunye nemigca inokurhoxisa enye kwenye.Ngoko isakhono sokuchasa i-jamming sinamandla kakhulu.
Ilungele ukusetyenziswa kwizikrini ezinezinga eliphezulu lekhowudi ngenxa yesisombululo esiphezulu.Ngenxa yokuba isikrini se-high-score 1400X1050 (SXGA) 1600X1200 (UXGA) izinga lesisombululo siphezulu kakhulu, izinga lekhowudi yesignali liphuculwe ngokuhambelanayo, ngokuxhomekeke kuyo yonke i-LVDS transmission iye yagqithiswa, ngoko basebenzisa indlela ezimbini ze-LVDS interface ukunciphisa izinga le-LVDS nganye.Uzinzo lwesignali oluqinisekisiweyo
