Then, in step S3000, the touch pad recognizes the second pressure applied by the user. In detail, the touch pad can recognize the pressure applied by the user when the user applies pressure higher than a specific force.

In detail, when the user applies a pressure higher than a specific force, the touch pad can recognize the pressure applied by the user and transmit the recognition of the pressure to the user through the vibration generated in the vibration member.

In step S3100, the user receives the vibration transmitted from the touch pad, and touches the second touch part or the third touch part to execute the input.

In detail, when the user desires to perform the first, second touch of the first touch part and the operation according to the pressure application, the second touch part can be touched. Alternatively, when the user does not perform the operation according to the first and second touches and pressures of the first touch unit, or when the user wants to perform another operation, the third touch unit can be touched.

In operation S3200, the touch pad performs a predetermined operation on the touch pad corresponding to the second touch unit and the third touch unit.

8 to 11 are views showing various application examples to which the touch pad according to the embodiments is applied.

Referring to FIG. 8, the touch pad according to the embodiments may be applied to a button of an elevator.

When the touch pad according to the embodiments is applied to the elevator button, the elevator button area can be simplified. When the elevator button is applied to an elevator of a high-rise building in detail, the number of elevator buttons can be increased. However, in the case of the touch pad according to the embodiments, various numbers can be implemented through buttons 0 to 9 and selection / The number of elevator buttons can be reduced, and the size of the button area can be reduced.

Further, since the touch pad transmits feedback according to the user's touch and pressure through the light, the display area and the vibration, the user can easily operate the elevator button through the touch pad.

Referring to FIG. 9, the touch pad according to the embodiments may be applied to a door lock.

When the touch pad according to the embodiments is applied to the door lock, since the touch pad transmits feedback according to the user's touch and pressure application through the light, the display area and the vibration, the user can easily operate the door lock through the touch pad .

Referring to FIG. 10, the touch pad according to the embodiments may be applied to electronic devices such as an air conditioner.

When the touch pad according to the embodiments is applied to an electronic device, the button area of the electronic device can be simplified. For example, when the touch pad according to the embodiments is applied to control the temperature and the like of the electronic device, the user can implement various numbers through the buttons 0 to 9 and the select and cancel buttons, The operation of the electronic device can be controlled.

Further, since the touch pad transmits feedback according to the user's touch and pressure application through the light, the display area and the vibration, the user can easily operate the electronic device through the touch pad.

Referring to FIG. 11, the touch pad according to the embodiments may be applied to a vehicle.

When the touch pad according to the embodiments is applied to a vehicle, the button area of the vehicle can be simplified. For example, when the touch pad according to the embodiments is applied to control the temperature inside the vehicle, the volume of the sound, the angle of the vehicle external device, etc., the user can select the buttons 0 to 9 and the select and cancel buttons It is possible to easily and quickly control the operation of the vehicle apparatus.

In addition, since the touch pad transmits feedback according to the user's touch and pressure through the light, the display area and the vibration, the user can easily operate the internal device of the vehicle through the touch pad.

The features, structures, effects and the like described in the foregoing embodiments are included in at least one embodiment of the present invention and are not necessarily limited to one embodiment. Further, the features, structures, effects, and the like illustrated in the embodiments may be combined or modified in other embodiments by those skilled in the art to which the embodiments belong. Therefore, it should be understood that the present invention is not limited to these combinations and modifications.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the present invention. It can be seen that various modifications and applications are possible. For example, each component specifically shown in the embodiments may be modified and implemented. It is to be understood that the present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof.
