Abstract:
A wireless handheld communications device with a liquid crystal display, especially, a field sequential liquid crystal display, includes a visual notification for a powered up, inactive state. The visual notification is preferably through a light emitting diode that may be part of the backlighting system for the LCD or may be independent from the backlighting system. The waveforms, periodicity, color selection, and color sequencing may be customizable by one or both of the manufacturer and user.
