On May 30, 2013, the US Patent & Trademark Office published a patent application from Apple that reveals a new flexible display invention. Apple has filed a number of flex display based patents over the last year including one for advanced concepts and features, another relating to the a next generation Smart Cover and yet another relating to unique functionality beyond the gimmickry of flex screen designs. Today's patent extends on the latter patent in that it ties a flex screen directly to an application such as Apple's GarageBand. In the future, playing the piano will be more realistic allowing the user to press the keys harder or softer to get the right sound that they're seeking. I'm sure that Apple is working on other applications for this new functionality but we'll just have to wait until they roll it out to see just how cool this could be.
