  • Publication number: 20160170250
    Abstract: 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.

  • Patent number: 9244550
    Abstract: 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.

  • Publication number: 20140210731
    Abstract: An electronic device includes a touch-sensitive display. The touch-sensitive includes a first set of drive electrodes and a first set of sense electrodes configured to detect touches on a first area of the touch-sensitive display, and a second set of drive electrodes and a second set of sense electrodes configured to detect touches on a second area of the touch-sensitive display. At least one controller is operably coupled to the first set of drive electrodes, the first set of sense electrodes, the second set of drive electrodes, and the second set of sense electrodes, and is configured to drive electrodes of the first set of drive electrodes while driving electrodes of the second set of drive electrodes. The first area is different from the second area.
