Abstract

This idea is a means for reducing the power consumption required to drive two light emitting devices for visual alert (allowing for color mixing) and/or dual source illumination of a panel. A unique electrical circuit utilizes two high frequency signal sources to sequentially strobe two light emitting devices at a rate higher than tha retina capture rate. The frequency sources are, in the preferred embodiment, already available from the apparatus the system is in (example a pager).
