In detail, the driving chip receives touch and / or pressure signals sensed by the electrodes from the first wiring electrode and the second wiring electrode and performs an operation according to a touch position and a pressure signal according to contact and force of the input device .

Hereinafter, an operation method of the touch pad according to the embodiment will be described with reference to FIGS. 6 to 8. FIG. 6 to 8, the case where the touch pad according to the embodiment is applied to a vehicle will be described as an example.

6 to 8, a method of operating a touch pad according to an embodiment includes a step S310 of touching a touch pad by a user, a step S320 of recognizing a touch of the user by the touch pad S320, Applying pressure to the touch pad (S330); The method may include a step S340 of sensing the pressure of the touch pad, a step 340 of controlling the pressure of the user, and a step S360 of performing the operation according to the pressure signal.

In step S310, the user touches the touch pad.

In detail, the user can touch the first touch part T1 or the second touch part T2 on the touch pad. For example, when the user tries to execute a menu according to the icon, the first touch unit T1 can be touched. Alternatively, when the user tries to input a character or the like or to execute a menu corresponding to the gesture of the user The second touch unit T2 can be touched.

In detail, when the user intends to execute the menu set in the icon I of the first touch unit T1, the user can touch or touch the icon area I to be executed.

In detail, the user can touch a plurality of areas of the touch pad. That is, the user can multi-touch one surface of the touch pad. For example, a user can touch two or more icons. That is, the user can touch two or more icons simultaneously or sequentially through a finger, a stylus pen, or the like.

Alternatively, if the user wishes to execute a menu the same as or different from the menu set in the icon I of the first touch unit T1, the second touch unit T2 can be contacted.

For example, the user can input a character or the like to execute a menu to be executed on the second touch portion T2 of the touch pad.

The operation of the touch pad according to such a character may be preset in the touch pad. In detail, the touch pad is pre-set to operate according to a specific character or symbol, and the touch pad can perform a predetermined operation by characters or symbols input by the user.

For example, the user can input the first letter of a character or a letter of a menu to be executed in the second touch part T2. For example, if the user wishes to execute a volume menu, he can input "volume", "sound", "VOLUME" or "V".

Alternatively, when the user desires to execute the navigation menu, he / she can input "navigation", "yes", "NAVIGATION", and "N".

That is, the user can select a menu to be executed by the user by inputting predetermined characters or the like on the touch pad to the second touch portion T2.

The user can touch two or more areas through an input device such as a finger or a stylus pen to execute a menu to be executed on the second touch part T2 of the touch pad.

For example, the user can repeatedly touch a plurality of areas of the second touch part T2 through the input device, or move the input device in the vertical direction or the left and right directions in a plurality of areas of the second touch part T2 have.

Further, the touch method and movement of the input device such as a finger can be performed simultaneously or sequentially. For example, one finger touches one area or a plurality of areas of the second touch part with one finger, and the other finger can be moved in a desired direction with a touch in one area or a plurality of areas of the second touch part.

That is, the user touches the first touch part T1 or the second touch part T2 or touches the plurality of areas of the first touch part T1 or the second touch part T2 according to the menu to be executed You can touch it.

Then, in step S320, the touch pad recognizes the user's touch and / or the touch position.

In detail, the touch pad can detect whether the user is multi-touching.

In detail, the touch pad has a function of changing the capacitance of the first electrode 221 and the second electrode 222, the position of each region that the user touches or touches in the first touch portion, The user can recognize the characters input by the user.

The touch pad recognizes touch positions, contact positions, characters or motions of a user, and can transmit a menu to be executed to the user. In detail, the touch pad can transmit a menu to a user via a voice by a user according to touches or contacts.

Alternatively, the touch pad may transmit a menu, which is performed according to characters input by a user, to a user through voice.

Accordingly, the user can recognize whether or not a menu desired by the user has been executed by touching the input touch area or inputting a character and then transmitting the voice information via the touch pad.

As shown in FIGS. 7 and 8, when the touch pad does not recognize the user's touch or does not recognize the multi-touch due to a malfunction of the user, the operation of the touch pad is terminated.

Then, in step S330 in which the user applies pressure to the touch pad, the user can apply a constant pressure to the touch pad. In detail, the user can apply a constant pressure to the touch pad when the input device recognizes the touch and the menu to be performed thereby matches the menu to be executed by the user.

Alternatively, if the user recognizes the touch by the input device and the menu to be performed thereby does not match the menu to be executed by the user, the user may touch or re-enter the character by adjusting the touch position, A predetermined pressure may be applied to the touch pad when the touch pad is in conformity with a menu desired to be executed by the user.

The user can touch two or more areas and apply pressure to two or less areas of the touch area.

For example, the user can touch two areas and apply pressure to both areas. That is, the user can apply pressure to the multi-zone.

Alternatively, the user can touch the two areas and apply pressure only to one area. That is, the user can apply pressure to only one area.

That is, the number of regions to which the pressure is applied may be equal to or less than the number of regions where the touch is performed.

Then, in the step of recognizing the pressure of the touch pad, the user can recognize the pressure applied to the touch pad. As described above, a force is applied on one surface of the touch pad by a pressure applied by a user, and the thickness of the intermediate layer having elasticity can be changed by the force.

Accordingly, the touch pad is moved by a first distance between the first electrode 221 and the second electrode 222 before the force is applied by the user and a change amount of the second distance after the force is applied by the input device It is possible to detect whether or not the user applies pressure and the magnitude of the pressure.

For example, when the pressure recognized by the input device is defined as 1 to 10, the input device can recognize that the user applies pressure to the touch pad when the user applies pressure of 3 or more to the touch pad have.

Whether or not the touch pad is recognized depending on the magnitude of the pressure may be preset in the touch pad. In detail, the touch pad is set to operate according to a specific size of pressure, and the touch pad can perform a predetermined operation according to the magnitude of the pressure applied by the user.

However, when the user applies a pressure of less than 3 to the touch pad, the user can not recognize that the pressure is applied to the touch pad. That is, in order to prevent the malfunction of the user, the touch pad can recognize the pressure applied by the user only when the user applies the pressure of a predetermined size.

That is, when the user touches two or more areas, the touch pad can recognize the pressure applied by the user only in the area where the pressure of three or more is applied.

When the user applies a pressure of 3 or more to the touch pad, the pressure device recognizes the pressure applied by the user and can transmit information that the pressure has been recognized to the user.

For example, it is possible to inform the user that the touch pad recognizes whether or not the user's pressure is applied through the vibration generated in the display screen or the touch pad of the dashboard or the windshield. That is, information such as whether the touch pad recognizes the pressure, whether or not the pressure of the area 1 is recognized, and whether the pressure of the multi-area of the area 2 is recognized is transmitted to the user.

When the user does not recognize the pressure applied by the user by applying a pressure of less than 3 to the touch pad, the touch pad can transmit information that the pressure is not recognized to the user. In this case, As shown in FIG. 8, after the user designates the touch position again, the user can apply pressure to the touch portion.

For example, information indicating that the pressure is not recognized can be communicated to the user through the vibration generated in the display screen or the touch pad of the dashboard or the windshield.

In this case, the user can apply a pressure of 3 or more to the touch pad by increasing the magnitude of the applied pressure, and when the touch pad recognizes the pressure of 3 or more, the vibration is generated on the display screen or the touch pad of the dashboard, It is possible to inform the user that the touch pad recognizes whether or not the pressure is applied.

Then, in step S350, the user controls the magnitude of the pressure applied to the touch pad.

In detail, the user can vary the magnitude of the pressure after receiving information that the pressure is recognized from the touchpad. That is, the user can change the magnitude of the pressure applied to the touch pad to various pressures between 3 and 10. That is, when the user applies the multi-pressure, the pressure of the same magnitude may be applied to the first and second regions, or the pressure of the different magnitudes may be applied to the first region and the second region.

Also, the user can input the execution by applying a certain pressure according to the desired operation.

If the menu is not a menu to be executed by the user, the menu can be reset by releasing the touch and ending the operation or by repositioning the touch position without inputting the execution.

This reset may be pre-set on the touchpad. In detail, the operation of initializing the operation when the user releases the touch is set in the touch pad, and the touch pad can perform predetermined operation by the non-touch pressure re-designated by the user.

Subsequently, in step S360, the touch pad executes a signal corresponding to the input. Various operations may be performed according to the magnitude of the pressure applied by the user.

In detail, the user can control the magnitude of the pressure to control the operation to be performed. For example, when the user selects the volume menu, the magnitude of the volume can be increased by gradually increasing the magnitude of the pressure, or by decreasing the magnitude of the pressure.

Alternatively, when the user selects a zoom-in menu, the display screen may be zoomed in or out as the pressure is gradually increased, or the display screen may be zoomed out and zoomed out as the pressure is gradually reduced.

Hereinafter, various operations implemented by the touch pad and the operation method thereof according to the embodiment will be described with reference to FIGS.

FIGS. 9 and 10 are views showing an operation of touching a plurality of areas of the touch pad according to the embodiment.

Referring to FIG. 9, the user can touch at least two areas of the first touch part. That is, the user can multi-touch two or more icons simultaneously or sequentially.

For example, when two or more icons are multi-touched simultaneously or sequentially, not only the function of the 1 icon and the 2 icon but also the other functions associated with the 1 icon and 2 icon are performed .

For example, when the 1 icon is an icon for performing a navigation operation and the 2 icon is an icon for controlling the magnitude of the volume, when the user touches and presses the 1 icon and the 2 icon simultaneously or sequentially, The volume of execution and navigation can be controlled simultaneously or sequentially.

Referring to FIG. 10, the user can touch at least two areas of the second touch part. That is, the user can simultaneously or sequentially multi-touch two or more areas in the two-touch unit.

For example, the user can implement two operations simultaneously or sequentially by performing the navigation through the gesture or the character with one finger in the second touch part and by controlling the volume through the direction movement with the other finger.

11 and 12 illustrate a method of operating navigation using a touch pad.
