针对某些仅绑定栅源驱动芯片而没有时序控制电路的液晶显示面板，设计了一款基于FPGA的 SOPC嵌入式系统的时序控制器。它利用FPGA的逻辑电路实现LVDS视频信号的解码、灰阶扩展、RSDS信号编码、显示控制时序转换等功能，并通过FPGA中Nios II软核的串行口设置参数，编程GAMMA及VCOM电压，参数具有掉电保护功能。时序控制器中还增加了BIT检测电路，可实时査询电路运行状态。该时序控制器电路集成度高、功耗低，结构简单，适合特殊应用，具有较高使用价值。

A FPGA-based SOPC embedded system timing controller is designed for some LCD panel driver chips which only bonding with source and gate circuits.It uses FPGA logic circuits to implement the functions such as LVDS video signal decoding, grayscale expansion, RSDS signal encoding, and control timing conversion display.Through the serial port setup parameters in FPGA soft-core Nios II, GAMMA and VCOM voltage can be programmed.Those parameters have power-down protection.The timing controller also adds BIT detection circuit which check the operation status in real-time.This high integration, low power consumption, simple structure timing controller circuit is suitable for special applications with high use value.
