Embodiment Construction

[0044] The present invention relates to display technology. More specifically, various embodiments of the present invention provide projection display systems in which one or more laser diodes and / or LEDs are used as light sources for illuminating images. In one set of embodiments, the present invention provides a projector system utilizing blue and / or green lasers fabricated using gallium nitride-containing materials. In another set of embodiments, the present invention provides a projection system having a digital light processing engine illuminated by blue and / or green laser devices. Other implementations also exist.

[0045] As mentioned above, traditional display types are often not sufficient. Pico projectors solve this problem by projecting large images (up to 60 inches or more) from handheld devices, allowing movies, web surfing and other images to be shared at the same size as the display size users are accustomed to. As a result, pocket projectors, self-contained ...
