More Information
Summary:A device display with a touch sensor includes a housing bezel, a plain clear substrate, and a display panel. The display includes a circuit board having a display aperture, the circuit board disposed between the clear substrate and display panel, and assembled with the housing bezel such that a portion of the display can be viewed through a bezel aperture. Sensor electrodes are disposed around the display aperture of the circuit board. A capacitive touch controller generates an electric field between sensor electrodes such that the electric field extends through and above the clear substrate. The controller can then detect a disturbance in the electric field above the clear substrate within and along a periphery of the bezel aperture.
