A company called Osram Opto Semiconductors
has created a new infrared LED that can be used in conjunction with
detectors to create ultra-thin touchscreens.
We've seen infrared used in
touchscreens before, most notably in Microsoft's Surface and recent e-readers from Barnes & Noble and Kobo. But, Osram's solution is complex enough to work in a multitouch tablet, while being as space-saving zForce.
At only 0.45mm tall the diodes and sensors can easily be crammed into a
bezel around a screen and sip just 35mW during regular use. Now the
company just has to convince someone to put the tiny IREDs in their
products.
