TOUCH PANEL

Embodiments relate to a touch panel (100; 200; 300) operable in a first haptic mode and a second haptic mode. The touch panel (100; 200; 300) includes first electrodes (Tx) and second electrodes (Rx, Dxa, Dxb) intersecting the first electrodes (Tx). The touch panel (100; 200; 300) further includes a...

Zusammenfassung:	Embodiments relate to a touch panel (100; 200; 300) operable in a first haptic mode and a second haptic mode. The touch panel (100; 200; 300) includes first electrodes (Tx) and second electrodes (Rx, Dxa, Dxb) intersecting the first electrodes (Tx). The touch panel (100; 200; 300) further includes an elastic dielectric member (130) disposed between the first electrodes (Tx) and the second electrodes (Rx, Dxa, Dxb) to separate the first electrodes (Tx) and the second electrodes (Rx, Dxa, Dxb). The first electrodes (Tx) are applied with a first voltage during the first haptic mode. The second electrodes (Rx, Dxa, Dxb) are applied with a reference voltage in the first haptic mode. A subset of the second electrodes (Rx, Dxa, Dxb) is applied with a second voltage to generate electrostatic force between the subset of the second electrodes (Rx, Dxa, Dxb) and a user's finger in the second haptic mode. The elastic dielectric member (130) vibrates in response to the first voltage applied to the first electrodes (Tx) in the first haptic mode.
