1. A display device, comprising:
- a base that includes a housing and a light source within the housing configured to generate light;
a projection chamber that includes a) a projection chamber housing, b) an optical modulation device configured to selectively transmit light generated by the light source according to video data included in a video signal provided to the optical modulation device, and c) a projection lens system for outputting light transmitted by the optical modulation device along a projection path; and
a positional interface coupled to the base and the projection chamber, the positional interface configured to stabilize the projection chamber in each of a first position relative to the base and a second position relative to the base, the positional interface further configured to facilitate moving the projection chamber from the first position to the second position.

Abstract
Described herein are devices that provide projection-type video output in a portable and flexible design. The design includes a projection chamber, a base, and an interface that permits relative positioning between the projection chamber and base. The base maintains the position of the display device. The projection chamber includes components responsible for the production of images based on received video data and components responsible for the projection of those images. Relative pointing between the projection chamber and base allows the projection chamber to be pointed—and an output projected image to be positioned—with minimal effort.

6. A display device, comprising:
-
a base that includes a housing and a light source within the housing for generating light; a projection chamber that includes a) a projection chamber housing, b) an optical modulation device for selectively transmitting light generated by the light source according to video data included in a video signal provided to the optical modulation device, and c) a projection lens system for outputting light transmitted by the optical modulation device along a projection path; and a bendable tubing, wherein the bendable tubing is coupled to the base and coupled to the projection chamber, the bendable tubing configured to facilitate moving the projection chamber from a first position relative to the base to a second position relative to the base when a threshold force or greater is applied to the bendable tubing, and the bendable tubing further configured to stabilize the projection chamber in either of the first position or the second position. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
