Electronic controller haptic display with simultaneous sensing and actuation

A haptic touch device comprising:

• an insulating substrate comprising a front surface and a rear surface;
• an array of front surface electrodes connected to and disposed on the front surface of the substrate,
• wherein the array of front surface electrodes making up a haptic layer of the haptic touch device are arranged in a first aligned pattern;
• and
• an array of rear surface electrodes connected to and disposed on the rear surface of the substrate,
• wherein the array of rear surface electrodes making up a sensing layer of the haptic touch device are arranged in a second aligned pattern that is substantially identically configured and substantially mirrors the first aligned pattern,
• wherein the front surface electrodes have a substantial mutual capacitance with the rear surface electrodes;
• and
• an electronic controller, the electronic controller comprising a high voltage switching circuitry in electrical communication with the array of front surface electrodes, the array of rear surface electrodes, and a main processor,
• wherein the main processor is configured to control the high voltage switching circuitry through a flying integrated circuit operating with a non-zero reference voltage offset from main digital control and processing.
