摘　　要：本文对目前广泛应用的真空荧光显示器件(VFD)的发光原理和性能特点进行了介绍。VFD是在真空环境下进行驱动的,因此其对应用环境具有很强的适应性、可靠性,使用寿命长,动作温度范围广,特别适用于车载显示。因此本文对VFD的连码、断码检测提出了解决方案,并详述了实现原理。The vacuum fluorescent display （VFD）devices are widely used.This paper introduces the operating principle of VFDs and their characteristics. VFD is drived in vacuum. It applies the environment to have the strong compatibility, the reliability higher, the service life is also long.The range of movement temperature is broader, specially is suitable to demonstration of the vehicle carries. This article is proposed the solution on the VFD examination, And more, it gives a realizable blue print.
