Abstract: AN IMPROVED DISPLAY SYSTEM IN WHICH A TRAVELING MESSAGE IS SMOOTHLY DISPLAYED ON A FIXED MATRIX IN ACCORDANCE WITH INPUT DATA WHICH IS RECEIVED AT ABRUPTLY VARYING RATES. A CIRCUIT IS PROVIDED FOR CAUSING THE MESSAGE TO CONTINUE TRAVELING FOR A PREDETERMINED TIME INTERVAL AFTER THE CHARACTER CORRESPONDING TO THE LAST RECEIVED INPUT DATA HAS BEEN FORMED ON THE DISPLAY MATRIX.

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.
