Abstract: A tactile feedback module not subject to a failure in function because of high-voltage arcing includes a circuit board and a piezoelectric unit. The circuit board includes spaced first connecting pad and second connecting pad. The piezoelectric unit includes a piezoelectric layer, a first electrode, and a second electrode. The piezoelectric layer is adjacent to the circuit board, and the first electrode and the second electrode are insulated from each other. A first voltage is applied to the first electrode and a second voltage different from the first voltage is applied to the second electrode, the piezoelectric layer generates a tactile feedback based on a voltage difference between the voltages. The disclosure also provides a method for making the tactile feedback module and a touch device.

Abstract: A touch panel capable of being simply manufactured includes a foldable substrate, a plurality of touch driving electrodes on the substrate, and a plurality of touch sensing electrodes on the substrate. The substrate includes two laminated layers achieved by folding. The touch driving electrodes are on one of the two laminated layers and the touch sensing electrodes are on the other of the two laminated layers. The touch driving electrodes and the touch sensing electrodes are formed by a same conductive layer on a surface of the substrate.
