IDT transmit touch information over DisplayPort's auxiliary channel
Still wondering if the future of display linkage really lies in DisplayPort? Hard to say for sure, but IDT's definitely making a good case for it with its latest demonstration. Integrated Device Technology has seemingly figured out how to shuffle touch information through DisplayPort's existing auxiliary channel, which simplifies and lowers the cost of integrating touch technology into tablets, laptops, AIO PCs, monitors, etc. It's being hailed as the world's first usage of the DisplayPort AUX channel to carry touch screen data, and if the prototype proves solid, it'll allow laptop manufacturers to eliminate USB interface communication from host to panel and reduce the number of wires that must pass through the display's hinge. And you know what that means -- slimmer, more flexible designs. IDT's not barking about a release date for its latest trick, but we're guessing it'll have display makers begging for access in no time flat.
