2 is a view illustrating a touch and haptic driving system 100 using an element 110 having input / output properties according to an embodiment of the present invention, which may solve the problems of the prior art as described above, and FIG. 3. Is a cross-sectional view of the touch and haptic driving system 100 using the device 110 having the input and output properties according to an embodiment of the present invention. As shown in FIG. 2 and FIG. 3, the touch and haptic driving system 100 using the device 110 having the input / output property according to the embodiment of the present invention may include the device 110 having a plurality of input / output properties. It may be configured to include, and may further comprise an electrode (130a, 130b).

The device 110 having the input / output property is a deformation that occurs in relation to the pressure, and may be in the form of a small film, and preferably may be a piezo device. As shown in FIG. 2, the device 110 having the input / output property may be plural in the present invention, and the device 110 having the input / output property of a predetermined size may be arranged in a tile form. The present invention includes a device 110 having a plurality of input and output properties arranged in a tile form as described above, and changes the output signal according to physical deformation occurring in the device 110 having input and output properties by a user's touch. The haptic may be provided by recognizing the coordinates touched through and transmitting the physical deformation occurring to the device 110 having the input / output property to the user.

At this time, the size of the device 110 having the input and output properties, the user can recognize the exact touch coordinates of the touched portion to produce an input signal, while the user recognizes the degree of deformation of the device 110 having the input and output properties You can make it big enough. Meanwhile, in the touch and haptic driving system 100 using the device 110 having the input / output property according to the embodiment of the present invention, as shown in FIG. 2, the device 110 having the input / output property has a lattice form. It may be implemented by installing in the plate 120 to form a tile.

The device 110 having the input / output property of the present invention may be implemented in the form of a small piezoelectric film such as piezo, and the input / output property is proportional to the force applied when the vibration or force is applied to the device 110 having the input / output property. The voltage is generated in the device 110 having a voltage, and on the contrary, when a voltage is applied to the device 110 having an input / output property, a mechanical force may be generated due to deformation of a shape. The touch and haptic driving system 100 using the device 110 having the input / output property according to the embodiment of the present invention uses the property of the device 110 having the input / output property having bidirectionality as described above, and thus forms a tile. Alternatively, by arranging the device 110 having input / output properties in a grid pattern, it is possible to recognize a user's touch input coordinates and provide local haptic feedback.

More specifically, the device 110 having the input / output property may be used as a sensor because the device 110 outputs an electrical signal corresponding thereto when physical deformation is applied from the outside. Therefore, in the present invention, the device 110 having a small input / output property may be arranged in a tile form to recognize coordinates to which a touch signal is input. As such, by using the device 110 having input / output properties having input and output functions at the same time, a separate touch sensor is not required, which is advantageous in miniaturization.

On the other hand, when the device 110 having the input / output property is activated by applying a voltage, its position may be shifted or its shape may be distorted. The type and extent of the deformation may be different from each other depending on the shape of the device 110 having the specific input and output properties used, but since the deformation can be restored to its original shape, the deformation may be transmitted to a user to be recognized as a haptic actuator. In addition, in the present invention, since the device 110 having the small input / output property in the form of a tile is disposed, the deformation of the device 110 having the input / output property may occur only in a local region in which a user's touch input is made, and the use of the device 110 may be performed. This can provide a variety of delicate haptic feedback to the user. In addition, since the device 110 having the input / output property itself serves as a haptic actuator, there is no need to provide a separate haptic actuator, and the device having the input / output property without control such as a micro controller unit (MCU). Since haptic is provided to the user at 110, it is possible to provide immediate and rapid haptic feedback.

A pair of electrodes 130a and 130b may be provided to contact both surfaces of the device 110 having input / output properties. As shown in FIG. 3, the electrodes 130a and 130b are provided on both sides of the device 110 having the input / output property to apply voltage to the device 110 having the input / output property. In this case, the electrodes 130a and 130b may be formed of a copper thin film, a silver thin film, or the like, and may be shaped to be deformed together according to the deformation of the device 110 having input / output properties.

4 is a diagram illustrating a detailed configuration of the touch and haptic driving system 100 using the device 110 having input and output properties according to an embodiment of the present invention. As shown in FIG. 4, the touch and haptic driving system 100 using the device 110 having the input / output property according to the embodiment of the present invention is provided by the device 110 having the input / output property as described above. The touch recognition unit 140, the haptic driver 150, and the controller 160 may be further configured. 2 and 3 have already been described in detail with respect to the device 110 having the input and output properties, other components will be described below.

The touch recognition unit 140 may convert the touch coordinates recognized by the device 110 having the input / output property into a signal and transmit the signal. That is, in the present invention, since the device 110 having the input / output property may serve as a touch sensor, the touch recognition unit 140 converts the touch coordinates recognized by the device 110 having the input / output property into a signal so that the control unit ( By transmitting to 160, various input signals can be effectively transmitted.

The haptic driver 150 may generate a haptic driving signal and apply the generated haptic driving signal to the device 110 having input / output properties. The haptic driver 150 may apply a driving signal to the device 110 having the input / output property through the electrodes 130a and 130b as shown in FIG. 3, and the coordinates of the device 110 having the input / output property are arranged. Different voltages can be supplied. Since each device 110 having a plurality of input / output properties may be separately controlled by the haptic driver 150, there is an advantage of providing haptic feedback in a local area.

Meanwhile, the haptic driver 150 may apply and apply different haptic driving signals according to a device to which the touch and haptic driving system 100 is applied or software installed and executed on the device. That is, the shape of the haptic feedback required for various devices may vary, and haptic feedback of various intensities and frequencies may be required according to the type of software installed and executed. Therefore, the haptic driver 150 may control the haptic feedback of the touch and haptic driving system 100 of the present invention by adjusting the amount of voltage corresponding to the required haptic feedback, a voltage application waveform, and the like.

The controller 160 may serve to control overall functions of the touch and haptic driving system 100 using the device 110 having input / output properties according to an embodiment of the present invention. In particular, as shown in FIG. 4, the controller 160 may receive the touch coordinates recognized by the touch recognizer 140 and provide various control signals. In addition, the controller 160 may transmit various control signals to the haptic driver 150 to adjust a voltage type applied to the device 110 having input / output properties from the power supply unit.

Meanwhile, the present invention may further include a signal detector (not shown). The signal detector may serve to sense a signal input to the device 110 having input / output properties from the outside.

FIG. 3 is a view illustrating a driving process of the touch and haptic driving system 100 using the device 110 having input / output properties according to the above. 5 and 6, the touch and haptic drive system 100 using the device 110 having input / output properties according to an embodiment of the present invention is driven by a touch input of the user 10. If an external force is applied from the outside by the user 10, the haptic feedback may be provided at the portion that receives the external force. That is, the device 110 having the input / output property may have different strengths of deformation according to the touch intensity applied by the user 10, and different strengths of deformation according to a distance separated from the recognized touch coordinates. have.

As shown in FIG. 5, when a touch is made by the user 10, the device 110 having an input / output property of an external force applied by the touch may be deformed to provide haptic feedback to the user 10. . In FIG. 5, the parts having different colors indicate the intensity of the haptic, and the degree of deformation of the device 110 having the input / output property is different depending on the touch intensity applied by the user 10 or the distance spaced from the touch coordinates. As a result, the degree of haptic feedback provided to the user 10 may be different. For example, as shown in FIG. 6, the haptic feedback provided to the user 10 may be a feeling of pressing a button, and the user 110 having the input / output property bends downwards to feel the feeling. (10) can be provided. As shown in FIG. 6, the haptic feedback may be the strongest at the touch input by the user 10, and the surrounding may be somewhat weak and the standby state may be maintained if it is completely out of touch coordinates. Therefore, according to the touch and haptic driving system 100 using the device 110 having the input / output property according to the embodiment of the present invention, since the haptic feedback can be provided only to the local part, the part touched by the touch pad itself. Haptic feedback may be implemented only in an area, thereby providing effective and detailed haptic feedback to the user 10.
