一、TFT液晶彩电中的同步与定时信号在液晶彩电等数字显示设备中必须具备、也是最为重要的同步信号和定时信号,包括:行同步信号、场同步信号、有效数据选通信号和像素时钟信号。1.像素时钟信号(DCLK)只要是数字信号处理电路,就必须有时钟信号。在液晶彩电等数字显示设备中,像素时钟就是一个非常 First, the TFT LCD color TV synchronization and timing signals in the LCD color TV and other digital display devices must have, and most important synchronization signal and timing signals, including: line synchronization signal, field synchronization signal, the effective data strobe signal and the pixel clock signal. 1. Pixel clock signal (DCLK) As long as the digital signal processing circuit, it must have a clock signal. In the LCD color TV and other digital display devices, the pixel clock is a very
