Until now, most projectors used either LED, LCD or DLP as the light source and they all possessed one bothersome problem: Focus needed to be adjusted manually. This was especially a big problem for portable projectors since they were meant to be carried around and the user had to adjust the focus every single time
Finally, a portable projector that doesn't require focus adjustment came out with laser technology. Focus-free meant that projected image was never out of focus, no matter what surface it was displayed on. Laser technology also made it possible for the projector to produce vivid colors incomparable to those by other LED, LCD and DLP projectors
There are currently 3 portable laser projectors in the world: SK Telecom's UO Smart Beam Laser, S company, and C company. S and C use technology very similar to that of an electron gun. One can see through a camera lens, electron beam wave flowing on the projected image like an analog TV. This laser beam can cause serious harm to human eye
The team behind the creation of UO Smart Beam Laser invented a highly-advanced laser technology that is completely safe to human eye. The Class 1 Laser used in the projector is registered with FDA. UO Smart Beam Laser's ingenious focus free and harmless laser technology has earned itself the 2016 CES Innovative Award
UO Smart Beam Laser is the only true portable projector in the world that can be used anywhere without a screen, used by children without worries, connect with various devices (smartphone, tablet, computer, media player, action camera, etc.) to enjoy crisp and vivid image with wireless & wired options
