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:
display a first image within at least a portion of the display based on handshake data provided by the one or more processing modules, wherein displaying of the first image via at least some of the plurality of pixel electrodes or the plurality of lines generates a handshake signal that is coupled into a user of the computing device being in contact with or within proximity to the display that facilitates coupling of the handshake signal through the user and transmission of the handshake signal to another computing device that includes a touchscreen that is configured to detect and receive the handshake 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 handshake signal from the user, wherein:
when enabled, the computing device configured to:
detect and receive a response signal from the another computing device;
process the response signal to determine whether the response signal compares favorably to an acknowledgement (ACK) signal; and
when enabled, the display configured to:
based on a determination that the response signal compares favorably to the ACK signal, display a second image within the at least a portion of the display based on other signal data provided by the one or more processing modules.
