Abstract
Disclosed is a personal portable device that includes a microprojector. The microprojector creates an image for display. The image is sent to a “beam-switching element” that shunts the image toward a selected display screen (e.g., a display screen on the device or an off-device projection). The image is then displayed on the selected screen. By commanding the beam-switching element to change its configuration, different screens can be driven by the same microprojector. The combination of a single microprojector with multiple display screens gives the personal portable device the flexibility of multiple displays while preserving space within the device and, in some embodiments, lowering power consumption. In some embodiments, the microprojector simultaneously drives more than one display screen. The driven display screens may display the same or different images, and the images displayed may be of the same or of different resolutions.
