Tuning fork oscillator driven light emitting diode display unit

A tuning fork oscillator driven display apparatus comprising

• a base,
• at least one display arm fixed to and extending from said base,
• a plurality of light sources mounted on said display arm in at least one line,
• at least one counterbalancing arm fixed to and extending from said base parallel to said display arm,
• means for oscillating said display arm and said mounted light sources and for oscillating said counterbalancing arm in the opposite direction,
• said at least one counterbalancing arm having a resultant inertial force during said oscillation equal and opposite to the combined resultant inertial force of said display arm and said mounted light sources, said resultant inertial forces being equidistant from said base,
• pulsing means for each of said plurality of light sources to permit at least one on light for each of plurality of positions through which said oscillator moves said line of light sources.

A tuning fork oscillator driven display apparatus comprising

• a supporting member,
• a display unit base,
• means for resiliently suspending said base from said supporting member,
• at least one display arm fixed to and extending from said base,
• a plurality of picture element sources mounted on said display arm in at least one line,
• at least one counterbalancing arm fixed to and extending from said base parallel to said display arm,
• means for oscillating said display arm and said mounted light sources and for oscillating said counterbalancing arm in the opposite direction fixed to and extending from said base, and
• pulsing means for each of said plurality of picture element sources to permit at least one turned-on picture element source for each of a plurality of positions through which said oscillator moves said line of picture element sources.
