摘要

介绍笔段式液晶的显示原理和控制方法

具体实现了数字仪表中的设计。该驱动方法采用了德州仪器公司的超低功耗单片机CC430F6137

使用其自带的LCD控制器

并以驱动GD46532液晶显示器为例

给出了温度采集系统的数值显示驱动方法和程序设计

并对该控制器独有的闪烁功能给出了说明。经实际程序测试

采用自带LCD控制器的数显仪表可最大程度上降低系统的尺寸

且可靠性高

程序可移植性好。

Abstract

This paper mainly introduces the segment type liquid crystal display principle and control methods in design and application of digital display instrument. The liquid crystal display system made by Texas Instruments with ultra low power microcontroller CC430F6137

which has a segment type LCD controller

can drive 96 segments at most. The GD46532 LCD module is designed by DaLian JiaXian electronic Co.

Ltd. The authors design the driving program in temperature sampling system

and also give the twinkle display way to display the value of sampled temperature. By application testing

the digital instrument with LCD controller can reduce the system size to the largest extent. The system is high reliable. Its program is easily portable in other systems.
