"Multi-touch LCD displays are suddenly all the rage, and it looks like Sony's planning on joining the party soon -- the company is touting a new 3.5-inch multi-touch LCD that uses optical sensing technology today. The 640 x 480 screen is made of what Sony's calling \"low-temperature polysilicon thin-film transistor\" tech, and it supports recognition of up to five fingers at a time, as well as pen input. Of course, there's no word on when we might see these screens pop up in actual devices, but let's hope Sony's product designers find a better use for them than chicken-scratching holiday greetings like the press photos.[Via Engadget Japanese]"^^<http://www.w3.org/2001/XMLSchema#string>
