本文對目前廣泛應用的真空熒光顯示器件(VFD)的發光原理和性能特點進行了介
紹。VFD是在真空環境下進行驅動的，因此其對應用環境具有很強的適應性、可靠性，使用壽命長，動作溫度范圍廣，特別適用于車載顯示。因此本文對VFD的連碼、斷碼檢測提出了解決方案，并詳述了實現原理。

Abstract：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．
