点阵式液晶显示器在仪器仪表开发中是一项新技术，国内在近两年才开始开发和使用．本文主要介绍目前市场上流行的、性能价格比优良的典型产品ＤＭＦ５００１、ＤＭＦ６８２（ＤＭＦ６５１）显示系统硬件、软件设计及开发使用中应注意的问题．文章最后给出点阵式液晶显示器在物探仪器中应用的一个典型实例．
Dot matrix liquid crystal display in the instrumentation development is a new technology, the domestic only in the past two years to start the development and use. This article mainly introduces the typical products DMF5001 and DMF682 (DMF651), which are popular on the market at present, and have good performance and low price ratio. The system hardware and software design and development and application should pay attention to. Finally, the paper gives a typical example of the application of dot matrix liquid crystal display in geophysical instruments.
