Pocket projectors are poised to explode, but will lasers or LEDs be the pre-eminent light source?

Melinda Rose, Senior Editor, [email protected]

Tiny projectors, known as pico or pocket projectors, are on the cusp of becoming the next big thing as they shrink to sizes practical for embedding into ever-smaller cell phones and other mobile devices as well as head-up displays for the military and auto industries. As these projectors continue to shrink, a battle is growing between LEDs and lasers to become the pre-eminent pico light source. The lamps first used as light sources for tabletop projectors or rear-projection televisions are large and power hungry, and they generate enormous amounts of heat, so manufacturers have turned...Read full article

    liquid crystal
    Liquid crystals are a state of matter that exhibits properties intermediate between those of conventional liquids and solid crystals. In a liquid crystal, the molecules are ordered like those in a crystal, but they can still flow like a liquid. This unique combination of structural order and fluidity gives liquid crystals their distinctive characteristics and makes them valuable in various technological applications, particularly in display technology. Key features and characteristics of...
