NEC 公司制造的256×32点矩阵真空荧光显示器件,有平板和模件二种形式,在它的真空封装中有驱动器 IC 芯片。NEC 正发运样品。传统产品有270个引线端子,而这种器件的外部引线端子只有9个,包括用来防护印刷板上零件的增强端子,引线端子总数减少到24或更少。由于驱动器 IC 芯片封装在真空外壳内,用于 IC 电源、地线、输入信号以及灯丝只需外引线。这种设计还可减少平板安装过程中引线板的工作时间。总的说,这种方法缩小了系统尺寸并降低整个系统成本10~30%。
256 × 32 dot matrix vacuum fluorescent display devices manufactured by NEC Corp. are available in the form of a flat panel and a module, and have a driver IC chip in a vacuum package. NEC is shipping samples. The traditional product has 270 lead terminals, and this device has only nine external lead terminals, including reinforced terminals for protecting parts on the printed board, reducing the total number of lead terminals to 24 or less. Since the driver IC chip is packaged in a vacuum enclosure, only external leads are needed for the IC power, ground, input signals, and filament. This design also reduces the lead time during flat panel mounting. Overall, this approach reduces system size and reduces overall system costs by 10-30%.
