Interface : Otu esi ekewa mara TTL na LVDS

Mgbama TTL bụ ọkọlọtọ ọkọlọtọ nke TFT-LCD nwere ike ịmata, na ọbụna LVDS TMDS eji emechaa na-etinye koodu na ndabere ya.The TTL akara akara nwere ngụkọta nke 22 (obere, uncalculated na ike) kewara n'ime RGB tri-agba mgbama, abụọ HS VS field synchronization signal, otu data na-enyere akara ngosi DE a elekere mgbanaka CLK, ebe RGG atọ-isi agba dị iche dị ka. na ọnụ ọgụgụ nke ibe n'ibe nke ihuenyo, na dị iche iche data ahịrị (6 ibe n'ibe, na 8-bit point) 6-bit ihuenyo na 8-bit ihuenyo tri-agba bụ R0-R5 (R7) G0-G5 (G7) B0- B5(B7) mgbama tricolor bụ mgbama agba, nhụsianya ga-eme ka ihuenyo gosipụta nsogbu agba.
