二、液晶面板的同步信号模式与定时液晶彩电主板上的SCALER(缩放)电路通过输出接口电路向液晶面板传送信号,常见的输出接口包括TTL、LVDS、TMDS、RSDS及TCON共5种,在液晶彩电中,主要采用TTL和LVDS接口。在TTL、LVDS这两种接口中,包括的信号主要有:RGB数据信号、像素时钟信号DCLK、行同步信号HS、场同步信号VS及有效 Second, the LCD panel synchronization signal mode and timing LCD SCALER (color) circuit on the motherboard through the output interface circuit to send signals to the LCD panel, the common output interface, including TTL, LVDS, TMDS, RSDS and TCON total of 5, Color TV, the main use of TTL and LVDS interface. In the TTL, LVDS these two interfaces, including the main signals are: RGB data signal, the pixel clock signal DCLK, line synchronization signal HS, field synchronization signal VS and effective
