In December we posted a report titled "Apple's Patented Idea of Displays Doubling as a Speaker Could Come to Life with New Gorilla Glass from Corning" which covered an MIT Technology Review article about Corning's new glass that had properties that could turn displays into speakers. Apple's first granted patent on this type of invention surfaced last August and today Apple was granted a second patent from the US Patent and Trademark Office that details this invention even further. The invention will apply to flexible OLED displays. According to Apple's patent filing, the kind of display may apply to a possible future version of Apple Watch in addition to other iDevices and Macs. That could open the door for Siri on Apple Watch down the road. That would fulfill the Dick Tracy component of Apple Watch. Now how cool would that be?
