用薄膜工艺制作的真空荧光显示器(下均略号为VFD)已广泛用到汽车仪器上,因为它们具有极好的温度和湿度特性,而且便于阅读,不会产生驱动困难。汽车仪器面板上采用真空荧光显示器还具有设计灵活、可采用几种颜色、工作电压范围内的集成电路驱动能力强。视觉分辨力好、体积小、重量轻、可靠性高、价格合理等优点。用丝网印刷法可形成显示图形,而采用薄膜工艺能得到更好的设计图形。以低压激发荧光粉可产生多种颜色,有关VFD的性能改进工作一直在进行。
Vacuum fluorescent displays made of thin-film technology (underscore VFDs) have found widespread use in automotive instruments because of their excellent temperature and humidity characteristics, ease of reading and ease of actuation. Automotive instrument panel with a vacuum fluorescent display also has a flexible design, can be used in several colors, operating voltage range of integrated circuit drive capability. Good visual resolution, small size, light weight, high reliability, reasonable price and so on. Screen printing method can be used to form the display graphics, and thin film technology can get a better design graphics. Exciting phosphors at low pressure produces a wide range of colors, and performance improvement on VFDs is ongoing.
