Abstract

The present structure involves a drive mechanism for apparatus which forms a multiple line character display by vibrating a single line of light-emitting diodes (LEDs). The electromagnetically actuated, electronicially controlled tuning fork oscillator drive is self-starting and will maintain the vibration amplitude to a preset adjustable magnitude.
