单片机与3种液晶显示器的接口技术

Interface Technology of MCU and Three Kinds of Liquid Crystal Display

液晶显示以其低辐射、低能耗、体积小、重量轻等优点被广泛应用,并且在大多数应用中常常使用单片机对液晶显示器进行控制,所以单片机与液晶显示器的接口技术成为一种很重要的技术。我们在产品开发中使用过多种液晶显示器,主要有段式液晶显示器、字符型液晶显示器和图形液晶显示器3种。不同的液晶显示器适用于不同的应用,根据不同的应用需求选用合适的液晶显示器,并综合考虑硬件和软件两个方面进行优化设计,达到了很好的实用效果。文中从硬件和软件两个方面全面描述了单片机与3种液晶显示器的接口技术。

Liquid crystal display（LCD） is widely used because of its low radiation, low power consumption, small size and light weight, and in most applications we often use MCU to control the LCD, so the interface technology of MCU and LCD becomes very important. We have used many kinds of LCD in product development, they are segment LCD, character LCD and graphic LCD. Different kinds of LCD are suited for different applications, we select suitable LCD according to application requirements, optimize the design of hard-ware and software, and get good effects. This paper presents the interface technology of MCU and three kinds of LCD in terms of their hardware and software.
