ABSTRACT:
A method and system for a thermal architecture and user adjustable keystone in a display device is described. The system includes a screen, a lens to project images, and one or more mirrors to reflect the images projected by the lens to the screen. A mirror assembly to adjust the images projected on the screen includes a first frame to pivot about a first axis, a second frame pivotably mounted in the first frame to pivot about a second axis, and a mirror moveably mounted in the second frame to reflect an image on a screen of a display device. The mirror is adapted to pivot about the first axis and the second axis via the first frame and the second frame to adjust the images on the screen. The base to which the screen is mounted has a thermal architecture that includes a plurality of vents to allow air to flow in and out of the base and an air movement device to move air from one or more heat sources away from the screen and toward the vents.
