Chiyankhulo : Momwe mungasiyanitsire dziwani TTL ndi LVDS

Chizindikiro cha TTL ndi chizindikiro chodziwika bwino chomwe TFT-LCD imatha kuzindikira, ndipo ngakhale LVDS TMDS yomwe imagwiritsidwa ntchito pambuyo pake imasungidwa pamaziko ake.Mzere wa chizindikiro cha TTL uli ndi chiwerengero cha 22 (chochepa, chosawerengeka ndi mphamvu) chogawidwa mu RGB tri-color sign, awiri HS VS kulumikiza kumunda chizindikiro, deta imodzi imathandiza chizindikiro DE chizindikiro cha wotchi CLK, kumene RGG mitundu itatu yoyambira ndi yosiyana ku chiwerengero cha zidutswa za chinsalu, ndi mizere yosiyana ya deta (6 bits, ndi 8-bit point) 6-bit point ndi 8-bit screen tri-color ndi R0-R5 (R7) G0-G5 (G7) B0- B5 (B7) chizindikiro cha tricolor ndi chizindikiro chamtundu, kusanja bwino kumapangitsa kuti mawonekedwe awonekedwe amtundu.
Zizindikiro zina za 4 (HS VS DE CLK) ndizo zizindikiro zowongolera, ndipo kusagwirizana kumapangitsa kuti mawonedwe awonekedwe osayatsa komanso osawonetsa bwino.Chifukwa mlingo wa chizindikiro cha TTL uli pafupi ndi 3V, umakhudza kwambiri kufalikira kwa mtunda wautali, ndipo kukana kusokoneza kulinso kosauka.Kotero ndiye pali mawonekedwe a mawonekedwe a LVDS, malinga ngati XGA pamwamba pa chiwerengero cha chinsalucho ikugwiritsa ntchito LVDS mode.

LVDS imagawidwanso mu njira imodzi, njira ziwiri, 6 bits, 8 bits, magawo, mfundo ndi magawano a TTL ndi ofanana.LVDS (chizindikiro chosiyanitsa chotsika) imagwira ntchito pogwiritsa ntchito IC yodzipatulira kuyika chilembo cha TTL mu siginecha ya LVDS, 6 bits ngati 4 masiyanidwe, 8 bits pamitundu 5, mayina a mzere wa data d0-D0-D1-D2-CK- CK-Ck-Ngati ndi skrini ya 6-bit, palibe D3 - D3 kuphatikiza ma siginecha, omwe amasungidwa pa bolodi yathu yamakompyuta.Kumbali ina ya chinsalu, palinso decoding IC ndi ntchito yomweyi, kutembenuza chizindikiro cha LVDS kukhala chizindikiro cha TTL, ndipo chinsalu chimatha ndi chizindikiro cha TTL, chifukwa mlingo wa chizindikiro cha LVDS uli pafupi 1V, ndi kusokoneza pakati. mizere ndi mizere akhoza kuletsa wina ndi mzake.Kotero mphamvu yotsutsa-jamming ndi yamphamvu kwambiri.

Ndizoyenera kugwiritsidwa ntchito pazithunzi zokhala ndi ma code apamwamba kwambiri chifukwa cha kusamvana kwakukulu.Chifukwa mawonekedwe apamwamba kwambiri a skrini 1400X1050 (SXGA) 1600X1200 (UXGA) ndiwokwera kwambiri, kuchuluka kwa ma code a siginecha kumakhalanso bwino, kudalira kufalikira konse kwa LVDS kwachulukidwa, kotero akugwiritsa ntchito njira ziwiri za LVDS mawonekedwe. kuchepetsa mlingo wa LVDS iliyonse.Kukhazikika kwa chizindikiro
