ABSTRACT A display unit is disclosed which utilizes at least one line of oscillated light sources such as LED's selectively turned on and off to create an alphanumeric display. The display unit comprises a supporting member from which a display unit base is resiliently suspended. A pair of display arms is fixed to said base and extend therefrom and a plurality of light sources are mounted on these display arms in at least one line. One or more counterbalancing arms are also fixed to and extend from the base parallel to the display arms. Means are pro- vided for oscillating the display arms and the light sources and for oscillating the counterbalancing arm in the opposite direction so as to counterbalance the dis- play arms, and pulsing means are provided for each of the plurality of light sources, preferably light emitting diodes, to permit at least one "on" light for each of a plurality of positions through which the oscillator moves the line of light emitting diodes.
