为了降低系统成本和功耗, 通过对液晶模块LTBHB203E1K和FPGA芯片EP1K30QC208-3的研究, 利用模块化的设计方法, 完成了手持式数字存储示波器显示部分的设计。给出了利用FPGA实现驱动液晶模块的方法以及数据存储与处理模块等的设计方法。实现了在液晶上显示输入信号波形、用户设置、输入信号参数等功能。该技术具有较高的实用性并已应用于产品之中。

Based on the knowledge about how to use LTBHB203E1KLCD module and EP1K30QC208-3FPGA, a display part of handheld digital storage oscilloscope was completed to reduce system cost and power consumption by modular design. The method of driving liquid crystal module is given and data storage and data processing modules are realized by FPGA. The design achieved such purposes as displaying input signal waveform, user settings, input signal parameters and so on. This technique has highly practical value and has been applied to the products.
