An indirect haptic device includes a substrate having a top surface and a bottom surface, and a plurality of haptic electrodes and a plurality of island electrodes arranged on the top surface. The device further includes a plurality of transmit electrodes and a plurality of receive electrodes arranged on the bottom surface, a position sensor, and a friction modulator. The device further includes a control device configured to apply bipolar electrical signals to the plurality of transmit electrodes to detect touch locations of a user's appendage and to modulate the friction between the user's appendage and the touch surface. Each of the plurality of haptic electrodes are substantially aligned with and capacitively coupled to a corresponding two of the plurality of transmit electrodes.

Bipolar projected haptics with balanced loading

A haptic touch screen including a lower layer including a plurality of control electrodes, an upper layer including a plurality of haptic electrodes, a middle layer between the lower layer and upper layer, where the haptic electrodes are not conductively connected to control electronics.

Haptic touch screen and method of operating the same

A touch panel includes a first substrate; a mask layer formed on the first substrate, and on a marginal region thereof; a first high density conductive layer covering the mask layer and the first substrate. An adaptive method for manufacturing the touch panel incorporating a HiPIMS-assisted-DC sputtering process is provided as well.
