RIM patents a dual capacitive/resistive touchscreen8
And RIM seems to get the idea. They've refiled a patent for a combined capacitive-resistive touchscreen. We say "refiled" because the patent seems identical to one filed in 2009. Further confusing us is the fact that Hitachi already showcased this combination screen technology in November of 2010. Lawsuit, anyone?
But there are more practical issues at play. For one thing, how much more expense would a hybrid touchscreen be? Would the extra expense really be worthwhile, considering how few customers would even notice? Perhaps if RIM marketed this combination touchscreen as a rugged corporate device, they might find a niche. But we suspect people are pretty satisfied with their capacitive screens.
