Abstract
An electronic device comprises a processor, a light source, and a controller coupled to the light source. The controller comprises logic to cycle the light source between an active state and an inactivate state at with a pulse duration that measures between 30 milliseconds and 100 milliseconds and jitter a time onset of the active state by a quasi-random time that measures between 0 and 30 milliseconds for one or more cycles. Other embodiments may be described.
Claims18
An apparatus, comprising:
- a controller to control a light source, wherein the controller comprises logic to:

- and
- jitter a time onset of the active state by a quasi-random time that measures between 0 and 30 milliseconds for one or more cycles.
