Maybe the solution to touchscreen displays that don't get washed out in direct sunlight is to skip the screen altogether. Researchers at Aerial Burton
are working to perfect a new kind of display technology that uses
lasers to produce 3D pixelated images that appear to hang in mid-air and
are still visible no matter how bright it is outside.
The
projector technology itself uses a 1kHz infrared laser (so it's
invisible to the human eye) that's fired into a rapidly moving mirror
that reflects and focuses the pulse onto specific points in the air. The
area where the laser is focused becomes ionized which then causes
visible photons to be released creating the bright white dots.
And
just like the display on your smartphone, the more dots (pixels) that
can be used to create the 3D image that seems to just hang in the air,
the more detailed and complex it can be. Initially the researchers are
hoping their new projection technology can be employed during
emergencies, providing highly visible signage and directions for escape
routes. But once a stadium gets its hands on the tech, imagine how cool a
3D floating scoreboard would be.
