Rotatably coupled touch screen displays

On a computing device comprising a first touch screen display comprising a first coupled side that is rotatably coupled to a second coupled side of a second touch screen display, a method comprising:

• at a first time:
• in the first touch screen 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 the first coupled side of the first touch screen display, and providing other signals at other frequencies to other drive electrodes in other frequency regions;
• and
• in the second touch screen display, providing a second signal at the first frequency to a second drive electrode in a different first frequency region abutting the second coupled side that is opposite to a second non-coupled side of the second touch screen display, and providing additional signals at the other frequencies to additional drive electrodes in additional frequency regions,
• wherein the first frequency region and the other frequency regions are ordered by frequency in ascending or descending order from the first non-coupled side to the first coupled side of the first touch screen display, and
• wherein the different first frequency region and the additional frequency regions in the second touch screen display are ordered by frequency in a same order as the order of the first frequency region and the other frequency regions from the second coupled side to the second non-coupled side of the second touch screen display.

A computing device, comprising:

• a processor;
• a memory storing instructions executable by the processor;
• a first touch screen display comprising,
• a first coupled side and a first non-coupled side that is opposite to the first coupled side,
• a first frequency region abutting the first non-coupled side,
• a first drive electrode in the first frequency region,
• other frequency regions located between the first frequency region and the first coupled side, and
• other drive electrodes in the other frequency regions;
• and
• a second touch screen display comprising,
• a second coupled side and a second non-coupled side that is opposite to the second coupled side,
• a different first frequency region abutting the second coupled side,
• a second drive electrode in the different first frequency region,
• additional frequency regions located between the different first frequency region and the second non-coupled side, and
• additional drive electrodes in the additional frequency regions;
• wherein the first coupled side of the first touch screen display is rotatably coupled to the second coupled side of the second touch screen display;
• and
• wherein the other frequency regions in the first touch screen display are positioned between the first frequency region in the first touch screen display and the different first frequency region of the second touch screen display, thereby spatially separating the first frequency region of the first touch screen display from the different first frequency region of the second touch screen display.
