ABSTRACT:
Described herein are devices that provide projection-type video output in a portable design. The projection-type display devices include a battery that stores electrical energy. The battery increases display device portability and flexible usage by permitting display device operation in locations not serviceable by a fixed power supply. For example, inclusion of a battery extends projector-type display device usage into a car, library, remote environment, or any other setting where fixed power outlets are not readily available or within power cord reach. To increase device endurance from a finite battery power supply, the present invention may also implement one or more hardware designs that reduce power consumption.
