基于FPGA的无机EL显示模块控制电路设计

介绍了一种无机EL显示模块控制电路的设计过程。该控制电路是基于PLANNAR公司的EL640.480-AF1无机显示模块,使用FPGA设计完成的。在FPGA内部设计了数据处理、存储器时序控制、显示模块时序控制等模块,代替了专用芯片的功能,用数字技术取代传统的模拟技术实现电路各模块,简化了电路;能够完成指定的显示模块的时序及控制方面的要求;适用于大部分的无机EL显示器件,通用性好。利用该控制电路,可以使无机显示模块作为计算机终端。

A design process of a control circuit for inorganic Electro-Luminescence display module is introduced. This control circuit is based on EL640.480-AF1 Inorganic Electro-Lumineseence display of PLANNAR Company and designed by FPGA. Some circuit functions, such as data processing, timing control for RAM, timing control for display, can be realized efficiently with FPGA instead of all the functions of integrated chips. The signal processing used digital way instead of traditional analog technology. So the circuit is simplified. It can fulfill the timing and control requirements for the designated display and is versatile at control.The design can drive most inorganic Electro-Luminescence display , so it can be universally used. Using the control circuit, the inorganic Electro-Luminescence display module can be used as a computer terminal.
