Claim:
1. A touch panel comprising: first electrodes; second electrodes separated from and intersecting the first electrodes, the second electrodes including a plurality of electrodes and adjacent electrodes, each of the plurality of electrodes disposed between a corresponding one of the adjacent electrodes and another corresponding one of the adjacent electrodes adjacent to said each of the plurality of electrodes; bridge electrodes, each of the bridge electrodes directly connected to one end of the corresponding one of the adjacent electrodes and one end of said another corresponding one of the adjacent electrodes, the bridge electrodes physically disconnected from the plurality of electrodes; and an elastic dielectric member disposed between the first electrodes and the second electrodes to separate the first electrodes and the second electrodes, wherein during a first haptic mode, a first voltage is applied to the first electrodes and a reference voltage is applied to the second electrodes to vibrate the elastic dielectric member, and wherein during a second haptic mode, (i) a second voltage is applied to one or more of the second electrodes to generate electrostatic force between the one or more of the second electrodes and a user's finger and (ii) a third voltage is applied to the first electrodes to generate additional electrostatic force between the first electrodes and the user's finger through the elastic dielectric member for providing electrostatic haptic effect to the user's finger.
