HAPTIC DISPLAY WITH SIMULTANEOUS SENSING AND ACTUATION

摘要

Touch interface devices having systems and methods for producing multi-point haptics utilizing simultaneous sensing and actuation, and electronic controllers for actuation thereof are disclosed. In a first configuration, two layers of electrodes are used, including a top layer for haptics near a touch surface of an insulating substrate and a deeper or bottom layer for sensing at a deeper layer or at the bottom surface of the insulating substrate, with the two electrode sets have substantially the same pattern as one another. In a second configuration, a single array of electrodes is used near a touch surface of an insulating substrate and serves as both surface haptic devices and sensing devices.
