In recent years, mobile devices such as PDAs, cell phones and laptops have become smaller and more powerful, while the end user markets for such products have become increasingly ubiquitous. However, the human interface elements (e.g. displays and keypads) are posing limitations on the ability of OEMs to continue to reduce the size of these devices. Symbol's laser projection display (LPD) technology can resolve this issue for the display element by providing a very small, power efficient display engine which produces full color, high quality images.


The LPD technology is analogous in function to cathode ray tube (CRT) technology, with the replacement of the CRT electron beams with three visible laser beams. The LPD image is created via two orthogonally moving mirrors, one of which is a high speed micromachined mirror. Unlike a CRT, however, LPD can be projected in free space on any light diffusing surface at any distance, and does not require a vacuum tube and phosphor screen.
