无论是TTL接口还是LVDS(低压差分信号)接口,都有像素时钟信号(DCLK)、行同步信号(HS)、场同步信号(VS)和有效数据选通信号(DE)。不同的是:对于TTL接口,这四种信号采用并行传输方式,即每个信号各占一条信号线;对于LVDS接口,这四种信号采用串行传输方式,其中,HS、VS、DE信号和RGB信号一起传输,单 Both the TTL interface and the LVDS interface have a pixel clock signal (DCLK), a horizontal sync signal (HS), a vertical sync signal (VS), and a valid data strobe signal (DE). The difference is: For the TTL interface, these four signals using parallel transmission, that is, each signal each occupy a signal line; for the LVDS interface, these four signals using serial transmission, including HS, VS, DE signal and RGB signals are transmitted together, single
