1. A computing device comprising:
one or more processing modules; and
a display that includes a plurality of pixel electrodes operably coupled to the one or more processing modules via a plurality of lines, wherein, when enabled, the display configured to:
transmit first data to another computing device based on a first signal having a first frequency that is generated by displaying a first image within the display based on first image data provided by the one or more processing modules, wherein the first image includes a first plurality of alternating stripes based on a first function of a frame refresh rate (FRR) of the display; and
transmit second data to the another computing device based on a second signal having a second frequency that is generated by displaying a second image within the display based on second image data provided by the one or more processing modules, wherein the second image includes a second plurality of alternating stripes based on a second function of the FRR of the display, wherein the first signal and the second signal are coupled into a user being in contact with or within proximity to the display that facilitates coupling of the first signal and the second signal through the user to the another computing device that includes a touchscreen that is configured to detect and receive the first signal and the second signal based on the user being in contact with or within proximity to the touchscreen of the another computing device that facilitates coupling of the first signal and the second signal from the user.
