Calaamadda TTL waa calaamad caadi ah oo TFT-LCD ay aqoonsan karto, oo xitaa LVDS TMDS-ka dambe ee la isticmaalo ayaa lagu dhejiyay iyada oo ku saleysan.Xariiqda calaamadda TTL waxay leedahay wadar dhan 22 (ugu yar, aan la xisaabin iyo awood) oo loo qaybiyay calaamadda saddex-midabka RGB, laba calaamadda is-dhexgalka goobta HS VS, hal xog ayaa awood u siinaysa calaamadda DE calaamadda saacadda CLK, halkaasoo RGG midabka saddex-saldhig uu ka duwan yahay marka loo eego ilaa tirada qaybaha shaashadda, iyo khadadka xogta kala duwan (6 bits, iyo 8-bit point) 6-bit screen iyo 8-bit screen tri-color waa R0-R5 (R7) G0-G5 (G7) B0- B5(B7) calaamada midabka tricolor waa calaamada midabka, si khaldan u qallafsanaantu waxay ka dhigi doontaa muraayadda muujinta cilladda midabka.
Calaamadaha 4 ee kale (HS VS DE CLK) waa calaamadaha kantaroolka, iyo isku xirnaanta khaldan waxay ka dhigi doontaa dhibcaha shaashadda oo aan si fiican u soo bixin.Sababtoo ah heerka calaamadda TTL waxay ku saabsan tahay 3V, waxay saameyn weyn ku leedahay gudbinta fogaanta fog ee heerka sare, caabbinta faragelinta sidoo kale waa liidata.Markaa markaa waxa jira shaadhka interface LVDS, ilaa iyo inta XGA ee ka sarreeya heerka xallinta shaashadda isticmaalaya habka LVDS.
LVDS waxa kale oo loo qaybiyaa hal kanaal, dual channel, 6 bits, 8 bits, fractions, mabda'a iyo qaybta TTL waa isku mid.LVDS (calaamadaha kala duwanaanta cadaadiska hooseeya) waxay ku shaqeysaa iyadoo la adeegsanayo IC gaar ah si loogu dhejiyo xarafka TTL-ga gelinta calaamadda LVDS, 6 bits sida 4 kala duwanaansho, 8 bits ee 5 kala duwan, magacyada xariiqda xogta d0-D0-D1-D2-CK- CK-Ck-Haddii ay tahay shaashad 6-bit ah, ma jiro D3 – The D3 plus set of signals, kaas oo ku xardhan sabuuradda kombayutaradayada.Dhinaca kale ee shaashadda, waxa kale oo jira IC-dejineed oo isku mid ah, oo u beddelaya signalka LVDS ee TTL, oo shaashadu waxay ku dhammaanaysaa calaamadda TTL, sababtoo ah heerka calaamadda LVDS waxay ku saabsan tahay 1V, iyo faragelinta u dhaxaysa xadhkaha iyo xadhkaha ayaa burin kara midba midka kale.Markaa awoodda ka-hortagga-jammaynta waa mid aad u xooggan.
Waxay ku habboon tahay in loo isticmaalo shaashadaha leh heerka koodka sare sababtoo ah xallinta sare.Sababtoo ah shaashadda sare ee 1400X1050 (SXGA) 1600X1200 (UXGA) heerka xallintu aad ayuu u sarreeyaa, heerka koodhka calaamadaha ayaa sidoo kale si la mid ah loo hagaajiyay, ku tiirsanaanta dhammaan gudbinta LVDS waa la buuxdhaafiyay, sidaas darteed waxay isticmaalayaan laba-dhinac LVDS interface yaree heerka LVDS kasta.Xasilooni calaamadeed oo la hubiyay
