摘　　要：由于解析度比模拟屏大,玻璃上的线路会更密,对工艺和背光的成本更高,在对颜色要求不高的工业仪器仪表领域,低成本的模拟彩色液晶屏已成首选。提出一种FPGA技术的彩色液晶驱动控制器的设计方案,使用硬件描述语言完成液晶时序和存储器接口,成功实现对AT056TN04的8种基本颜色的显示,既克服单色液晶模块色彩单调,颜色丰富的数字彩色屏价格贵的缺点,又具有显示数据量小、用户操作简单方便的优点。适当调整可以方便应用于其他模拟彩色液晶屏,在工业仪器仪表中具有较好的应用价值。Duo to the denser circuit, better workmanship, higher cost, the low cost color analog screen is preferred in the production of test and measurement equipments. A driving controller based on FPGA for analog screen is designed. It implements the AT056TN04 driving,the refresh of LCD,and external user interface. Simulations and system test results show that the design works well in the display of 8 kinds of basic colors. The designed driving overcomes both the monotony of monochrome LCD module and the high price of the real color digital LCD module. By appropriate adjustment, it can be easily applied to other LCD module and can be widely used in the industrial instrumentations.
