中文摘要：
对于嵌入式系统的显示电路模块设计,要根据不同的显示屏类型来决定。对于一些可供多种产品研发的通用系统平台,要根据不同产品的需要设计成可支持多种的屏幕。文章以EP9312的系统平台为例,详细介绍了同时支持TFT、CSTN、DSTN、LVDS、VGA屏幕的显示模块的硬件设计。给出了硬件电路设计的方法及注意事项,有利于促进多种类型的屏幕在嵌入式设备中的灵活应用。显示模块在系统整合后运行稳定,经过实际测试表明,电路的设计符合了嵌入式系统的要求,满足了设计需要。目前该显示模块设计已在银税类终端产品上得到应用。
英文摘要：
The display circuit design of embedded system must base on the different types of display screens. For some all-purpose embedded system which provided to different products, it must be designed to support many different types of display screens. This paper introduced a hardware design of display circuit of embedded system with EP9312 which support TFT,CSTN,DSTN, LVDS, VGA at the same time, which is propitious to the design of display circ.uit of embedded system. The display circuit runs steady after the system has integrated. The test shows that the design is up to the mustard for the embedded system. The display circuit design has used in the bank and taxation terminal product.
