Publication number: 20160170250Abstract: An electronic device includes a stack assembly and a cover glass. The stack assembly includes an electronic paper display sub-assembly for rendering content, a front light sub-assembly for illuminating the electronic display sub-assembly, and a capacitive touch sensing sub-assembly for detecting touch inputs. The cover glass includes two apertures for the placement of control buttons for the electronic device. Prior to assembly of the electronic device, the cover glass is strengthened after the two apertures are formed so as to strengthen the interior edges of the apertures.Type: ApplicationFiled: December 11, 2014Publication date: June 16, 2016Inventors: Hany Mounir Ghali, Gregory Turner Witmer, Chin Siong Khor, Anoop Menon, Premal Vinodchandra Parekh, Robert L.D.

Patent number: 9244550Abstract: A method includes identifying a first plurality of drive frequencies at which drive electrodes of a touch-sensitive display of an electronic device are driven, wherein the first plurality of drive frequencies includes a first frequency and a second frequency. A first noise value at the first frequency is determined. When the first noise value meets a first threshold value and the first noise value is less than a second threshold value that is greater than the first threshold value, a second noise value at the second frequency is determined by the electronic device and, in response to determining that the second noise value is less than the first threshold value, driving the drive electrodes at the second frequency. When the first noise value meets the second threshold value, a third frequency at which the drive electrodes are driven is identified by the electronic device, wherein the third frequency is not one of the first plurality of drive frequencies.Type: GrantFiled: August 16, 2013Date of Patent: January 26, 2016Assignee: BlackBerry LimitedInventors: Amit Pal Singh, Premal Vinodchandra Parekh, Rohan Michael Nandakumar, Byron Allen Schiel, John Edward Dolson
