Abstract
Examples are disclosed relating to computing devices and methods for performing capacitive touch detection in rotatably coupled displays. In one example, a method comprises: in a first display, providing a first signal at a first frequency to a first drive electrode in a first frequency region abutting a first non-coupled side opposite to a first coupled side. Other signals at other frequencies are provided to other drive electrodes in other frequency regions. In a second display, a second signal at the first frequency is provided to a second drive electrode located in a different first frequency region abutting a second coupled side opposite to a second non-coupled side. The other frequency regions of the first display are positioned between the first frequency region and the different first frequency region, thereby spatially separating the first frequency region from the different first frequency region.
