Patently Apple has the news that Apple has filed for another touchscreen display patent, but here's the catch: this one's probably not for a tablet! Or at least, not for the tablet we're expecting. The patent, which covers the idea of a thinner and brighter touchscreen display by combining the touch and pixel display elements (basically including the capacitive and pixel elements in the same hardware), could actually be used in any of Apple's devices, from the iPhone and iPod touch, to future versions of their laptops. And yes, it could be used in a potential tablet, but really, this is more of a way to create touchscreens anywhere rather than specifically a tablet-only function.
Note that this is also different from the dynamic tactile display Apple patented a little while ago. Personally, I'd rather see the much more inventive tactile display used in the hopefully soon-to-be-unveiled tablet -- I'd love to finally get some touchable feedback from touchscreens. But of course Apple will use what they think is best. Having a quicker and brighter display to go along with a multitouch screen wouldn't be a bad thing, either.
