1967年,日本的中村正用低能电子发光原理、以ZnO:Zn为发光粉发明了第一只真空荧光显示器件(Vacuum Fluorescent Display,VFD),伊势公司迅速将其商业化,并取得了极大的成功。产品由数码管发展到平板多位数码、文字和符号的复合显示屏、矩阵屏,以及显示图像的视频显示屏;颜色由单一的蓝绿色发展到多色;广泛用于仪器仪表、办公设备和家用电器等,VFD在近几年平板显示市场中占第二位。从发明开始它就有下列优点:
In 1967, Japan’s Nakamura was using the principle of low-energy electroluminescence to create the first Vacuum Fluorescent Display (VFD) using ZnO: Zn as a luminescent powder. Ise Corporation rapidly commercialized it and achieved extremely high voltage Big success. Products from the digital tube to the development of a number of flat-panel digital, text and symbols of the composite display, the matrix screen, as well as the video display image display; color from a single blue to multicolor; widely used in instrumentation, office equipment and Household appliances, etc., VFD in the flat panel display market in recent years accounted for second. From the beginning of the invention it has the following advantages:
