Patent ID: 8773373

Claim:
A display apparatus with a touch panel comprising: a touch panel including a touch switch operable to detect that the touch switch is touched by an operator with a finger; a piezoelectric actuator operable to vibrate the touch panel when the touch switch is touched by the operator with the finger, the piezoelectric actuator including a pair of input electrodes disposed at predetermined intervals on a back surface of the piezoelectric actuator; a circuit substrate facing the back surface of the piezoelectric actuator and spaced away from a back surface of the touch panel, the circuit substrate including at least a drive circuit for driving the piezoelectric actuator, the drive circuit including a pair of output electrodes; and a support structure for supporting the piezoelectric actuator on a front surface of the circuit substrate, disposed between the piezoelectric actuator and the circuit substrate, wherein: the piezoelectric actuator is mechanically connected to the back surface of the touch panel such that vibration generated when the piezoelectric actuator is driven by the drive circuit may be transmitted to the touch panel; the support structure is formed of a pair of electrically conductive support members having electrical conductivity and elasticity and capable of electrically connecting the pair of input electrodes of the piezoelectric actuator and the pair of output electrodes of the drive circuit; and the pair of electrically conductive support members are disposed between the pair of input electrodes and the pair of output electrodes for supporting the piezoelectric actuator such that the vibration of the piezoelectric actuator may not be suppressed as much as possible.
