    • A method for a band display of at least two analog signals in a display device having a display scale with a plurality of successive display elements of which a part defined by an analog signal in each scanning cycle is made luminous by a specified scanning frequency to produce an analog display, comprises changing the current supply to the display elements and changing the scanning speed of the display elements to produce a three level variation of light intensity on the same display scale. A light spot of a specified length displaying the value of a first analog signal is provided on the display scale by a first level of light intensity. A uniform light column displaying the value of a second analog signal is provided on the display scale by a second, middle, level of light intensity. A separation is provided on the display scale between the first analog signal display and the second analog signal display by a third level of light intensity.
    • 一种用于在具有多个连续显示元件的显示标尺的显示装置中的至少两个模拟信号的频带显示的方法,其中由每个扫描周期中的模拟信号限定的部分被指定的扫描频率发光,以产生 模拟显示器包括改变对显示元件的电流供应并改变显示元件的扫描速度,以在相同的显示比例尺上产生三级光强度变化。 显示第一模拟信号的值的指定长度的光点以第一级光强度在显示比例上提供。 显示第二模拟信号的值的均匀的光柱在第二,中等光强度下在显示比例上提供。 在第一模拟信号显示和第二模拟信号显示之间的显示比例上提供具有第三级光强度的分离。
