    • To provide for optical indication of output values relating to the operating conditions, or other parameters for display on the dashboard of a display panel, for example on automotive vehicles, a display panel (10) has a plurality of indicating blocks (15a . . . 15k) distributed thereover. A logic circuit, for example provided by a micro-processor (12) supplies data over data busses (21, 41) to the respective indicating blocks, which can be connected in series (FIGS. 2, 4) or in parallel (FIGS. 5-7). The logic circuit is connected through suitable connecting lines (13) with sensor inputs, providing ambiant, or operation or operating data. The logic circuit, additionally, generates data of its own, for example time outputs. The indicating blocks each include a shift register (17, 18, 50) which is connected to a data line, the stages of the shift register being connected to respective indicating elements (16, 53) which, together, formed the indicating blocks--for example LCD elements--so that the shift state of the respective shift register will provide suitable output indications. For example, if a shift register has eight positions, and four sequential positions have a 1-signal and four other sequential positions have a zero-signal, a line can be displayed representative of half-full state of a fuel tank.
    • 为了提供与操作条件相关的输出值的光学指示或用于在显示面板的仪表板上显示的其它参数,例如在汽车上,显示面板(10)具有多个指示块(15a ...) 15k)。 例如由微处理器(12)提供的逻辑电路将数据总线(21,41)上的数据提供给可以串联连接的各个指示块(图2,4)或并联连接(图4和图4)。 5-7)。 逻辑电路通过具有传感器输入的合适的连接线(13)连接,提供方便或操作或操作数据。 另外,逻辑电路产生自己的数据,例如时间输出。 指示块各自包括连接到数据线的移位寄存器(17,18,50),移位寄存器的级连接到相应的指示元件(16,53),它们一起形成指示块,用于 例如LCD元件,使得各个移位寄存器的移位状态将提供合适的输出指示。 例如,如果移位寄存器具有八个位置,并且四个顺序位置具有1-信号,另外四个连续位置具有零信号,则可以显示代表燃料箱的半满状态的线。
