Abstract: A control system for a data display system such as a scoreboard, message board or the like wherein display indicators having location addresses, on the board are addressed and actuated through a logic system which first receives and stores address data pertaining to a particular indicator, receives display character data, and responsive to the receipt of the character display data automatically reads out the address data to the board for enabling the desired indicator followed by the display character data to actuate it to display the desired character. Indicator circuits are provided for the control of each indicator comprising semiconductor switches which are reset by the addressing of the indicator and actuated to display the desired character responsive to the receipt of the display character data. A memory storage is also provided to cause the display of repeatedly used messages and animated characters.

Abstract: A completely electronic traveling message display system in which the input data is loaded into a buffer at the rate received and read out to a lamp encoder for actuating the lamps at a rate dependent on but nonsynchronous with the input rate. A control circuit determines the contents of the buffer and controls the readout rate so that a smooth transition is made in the visual display rate despite fast changes in the rate of input. A shift register is shown for sequentially enabling the lamps in a lamp matrix display board and the control circuit controls the shift rate through the register. Provisions are made to fire the lamps a controlled number of times for each shift of the shift register and only for a short period to prevent image distortions to the observer. The brightness of the display is both automatically and manually controllable to adjust for variations in the display rate and for ambient light conditions.
Abstract translation: 一种完全电子行驶信息显示系统，其中输入数据以接收和读出的速率加载到缓冲器中，灯编码器用于以与输入速率相关但不是非同步的速率致动灯。 控制电路确定缓冲器的内容并控制读出速率，使得尽管输入速率的快速变化，以可视显示速率进行平滑过渡。 显示了一个移位寄存器，用于顺序启用灯泡矩阵显示板中的灯，控制电路通过寄存器控制移位速率。 规定了对移位寄存器的每次移位的控制次数进行控制，并且仅在短时间内防止对观察者的图像失真。 显示器的亮度可自动和手动控制，以适应显示速率和环境光线条件的变化。
