Abstract
A portable electronic apparatus has light sources that can be controlled to produce decorative or informational effects. Each light source is controlled by the combination of an enable signal from a 1-bit port of a controller and a PWM signal from a PWM signal from the controller. Each PWM signal is used to control a plurality of light sources in parallel whereas each 1-bit enabled signal controls, generally, only one. The light sources are preferably arranged to shine through soft structures on the apparatus.
