The touch pad 120 will be described later. In the present embodiment, the mode selection button 170 may be provided as a metal dome key, and a plurality of mode selection buttons 170 may be disposed in the circumferential region of the touch pad 120.

In the present embodiment, four first to fourth mode selection buttons 170 are provided, but the scope of the present invention is not limited to the number and location thereof. In addition, the mode selection button 170 may be applied as a tact switch in addition to a metal dome key.

Meanwhile, in the present embodiment, the touch pad 120 and the mode selection button 170 form the integrated module, the touch and circuit unit 110. The structure of the remote controller will be described in detail.

The remote controller of the present embodiment includes a bottom case 101 and a bottom case 106 that are detachably assembled to each other, and a touch and circuit unit assembly 110 disposed therebetween.

The bottom case 101 is a structure forming a lower region of the remote controller, and a wireless module 102 is provided at one side thereof, and the touch and circuit assembly 110 is fixed at the central region.

As described above, the touch and circuit unit assembly 110 indicates a component in which the touch pad 120 and the mode selection button 170 are modularized, and the touch pad 120 and the mode selection button 170 are shown in FIG. 111).

3, a touch pad deco 115 for inputting a touch operation is provided on an upper surface of the touch pad 120, and the mode selection button 170 is operated around the touch pad deco 115. A mode select button deco 116 is provided.

The mode selection button deco 116 has an opening 116a at which a touch pad deco 115 is exposed, and an operation surface disposed outside the touch pad deco 115 to operate the mode select button 170. To form.

The top case 106 is a structure detachably coupled to the bottom case 101 with the touch and circuit unit assembly 110 interposed therebetween. In the central region of the top case 106, a penetrating portion 107 is formed to expose the touch pad deco 115 and the mode select button deco 116 to the outside.

Meanwhile, the touch pad 120 will be described with reference to FIGS. 3 and 4. The touch pad 120 applied to the remote controller of the present exemplary embodiment is provided for inputting a touch operation, such as operating a pointer or inputting a character on a display screen.

The touch pad 120 is organically operated with the touch pad decor 115, and includes a circuit board 140, an elastic body 150, a spacer 160, an elastic pressing member 165 provided with an electrode 145, And a common pressurizing plate 168.

As described above, the touch pad decor 115 is a part for inputting a substantial touch operation such as operating a pointer or inputting a character that appears on the display screen. Therefore, the exposed surface, which is the upper surface of the touch pad deco 115, is always exposed to the outside, and the user may input a touch operation while touching the upper surface of the touch pad deco 115 with a finger or a touch fan.

Although the touch surface, which is the upper surface of the touch pad deco 115, is shown flat in the present embodiment, a plurality of recognition protrusions (not shown) may be further provided on the touch surface, which is the upper surface of the touch pad deco 115. A plurality of recognition protrusions may be provided in the corner region of the touch surface, and serve as a guide for recognizing where the touch surface is located by the sense of a finger even if the touch surface is not seen. In other words, even if the touch surface is not seen, the touch surface may be recognized by the sense of a finger so that a software-defined function may be easily executed.

The circuit board 140 is provided on one side of the touch pad decor 115 and may be a printed circuit board (PCB) on which a plurality of electronic components are mounted.

The electrode 145 is provided on the upper surface of the circuit board 140. When touching the touch surface, at least one of the touch position and the touch pressure (hereinafter, referred to as the same term as the touch force) may be sensed based on the action of the electrode 145. The electrode 145 may be coupled to the circuit board 140 or may be provided in a mounted form. When the touch surface is touched, the principle of sensing the touch position and the touch pressure based on the action of the electrode 145 is already disclosed in the prior patent literature, so a detailed description thereof will be omitted.

The plurality of electrodes 145 detects whether the touch operation is input, the touch position and the touch based on the detected amount or change in capacitance after detecting the amount or change in capacitance generated between the elastic body 150 at the corresponding position. At least one of the pressure information, for example, the present embodiment serves to transmit the information to the controller (not shown) so that the information of the touch position and the touch pressure is recognized.

The electrode 145 is controlled by a controller (not shown), in which case the controller may be electrically connected to any one side of the elastic body 150, which may be made of a conductive metal material, and the electrode 145.

However, if the elastic body 150 is made of a non-conductor like plastic, after the conductive electrode pattern (not shown) through which the electrically conductive conductive pattern (not shown) is applied to one surface of the elastic body 150 facing the electrode 145, the controller is elastic body The conductive electrode pattern 150 and the electrode 145 may be electrically connected to each other.

In the present embodiment, when a touch operation is input, the controller detects the amount or change in capacitance generated between the elastic body 150 and the electrode 145 and then touches the touch action based on the detected amount or change in capacitance. Whether or not the input, the touch position and the touch pressure can be controlled to be recognized.

The elastic body 150 is disposed between the touch pad decor 115 and the circuit board 140, and elastically deforms toward the electrode 145 when the touch operation on the touch surface, which is the upper surface of the touch pad decor 115, and the touch operation disappears. Has an elastic force to return to its original position.

The elastic body 150 is elastically deformed due to the touch pressure generated when the touch operation is performed, that is, when the touch surface of the touch pad decor 115 is touched by a finger or the like, and thus the elastic body 150 is formed of the capacitance generated between the electrode 145 and the electrode 145. It changes the size.

In other words, the elastic body 150 is disposed between the touch pad decor 115 and the circuit board 140, and has an elastic force that is elastically deformed toward the electrode 145 during the touch operation and returns to its original position when the touch operation is extinguished.

The elastic body 150 may be provided as various types, but in the present embodiment, the elastic body 150 is applied to a leaf spring made of a conductive metal material.

The elastic body 150 is divided into an assembly part 151, a driving part 153, and an elastic part 155 according to its position. Of course, the assembly part 151, the driving part 153, and the elastic part 155 may be functionally divided, and may be integrally provided at the time of manufacture.

The assembly part 151 is a portion formed along the outer circumferential direction of the elastic body 150 and is used as an area to be assembled to the circuit board 140 together with the spacer 160. Therefore, a plurality of through holes 152 are formed through the assembly part 151.

The driving part 153 substantially approaches the electrode 145 during the touch operation with respect to the touch surface, thereby generating a magnitude or a change amount (also referred to as a capacitance value) between the electrode 145 and the electrode 145.

More specifically, in the present embodiment, during the touch operation, the driving part 153 of the elastic body 150 is moved toward the electrode 145 so that the gap between the driving part 153 of the elastic body 150 and the electrode 145 is moved. As this change, the capacitance value changes.

In the present exemplary embodiment, when the pressing force is applied to the elastic body 150, the driving part 153 may be moved toward or spaced toward the electrode 145 while being substantially moved in parallel with the circuit board 140. In this case, when the pressing force is applied to the elastic body 150, the driving part 153 may be driven to approach or spaced apart from the electrode 145 while keeping the state parallel to the electrode 145, thereby increasing the size of the capacitance. Alternatively, the reliability can be improved in calculating the amount of change.

The elastic part 155 is connected to the assembly part 151 and the driving part 153, and serves to provide an elastic deformation or restoring force to the driving part 153. That is, the elastic part 155 serves to allow the driving part 153 to approach or be spaced apart from the electrode 145 while keeping the driving part 153 in parallel with the electrode 145 based on the assembly part 151.

The elastic part 155 is provided with a plurality of elastic deformation or restoring force slit 156 to double the elastic deformation or restoring force.

The elastic deformation or restoring force multiplying slit 156 is formed by partially combining an arc shape and a straight shape, but a bent shape may be added beyond those shown.

In this case, the elastic deformation or restoring force slit 156 may be regularly arranged symmetrically with respect to the front surface of the elastic body 150. In this case, when the pressing force is provided to the elastic body 150, the driving part 153 is The electrode 145 may be approached or spaced apart while being in parallel with the electrode 145.

Since the elastic part 155 plays such a role, it is preferable that the elastic part 155 is connected to the assembly part 151 and the driving part 153 in a minimum area. Small thicknesses may be advantageous. However, this is not necessarily the case.

As such, when the elastic body 150 including the assembly part 151, the driving part 153, and the elastic part 155 is used, the capacitance between the driving part 153 of the elastic body 150 and the electrode 145 may be reduced. The reliability of the size or the amount of change can be improved to reduce the error of the touch input.

In the present embodiment, four driving parts 153 and four elastic parts 155 are provided in the elastic body 150, but this is only one example. Therefore, the scope of the present invention can not be limited to the illustrated shape.

The spacer 160 is disposed between the circuit board 140 and the elastic body 150 so that the elastic body 150 returns to its original position when there is no touch operation. As such, the spacer 160 is disposed between the circuit board 140 and the elastic body 150 to support the elastic body 150 with respect to the circuit board 140.

Although the spacer 160 is illustrated as a disk-shaped plate structure in which a through part is formed in a region where the driving part 153 and the elastic part 155 are positioned, the shape and arrangement position of the spacer 160 may be changed at any time. . For example, unlike the drawings, the spacer 160 may be a plurality of separate pieces.

The elastic pressing member 165 is disposed between the driving part 153 of the elastic body 150 and the touch pad deco 115 to substantially press the driving part 153 of the elastic body 150 during the touch operation of the touch surface. Do it.

When there is no elastic pressing member 165, since the touched pressure may not be transmitted to the driving part 153 of the elastic body 150 even if the touch surface is touched, the elastic pressing member 165 is provided.

Since the elastic pressing member 165 serves to transmit the pressing force generated during the touch operation of the touch surface to the driving part 153 of the elastic body 150, the elastic pressing member 165 may be a driving part of the elastic body 150. It is advantageous to have a size corresponding to the size of 153). In this embodiment, one elastic member 165 is disposed for each driving part 153.

The common pressing plate 168 is disposed between the plurality of elastic pressing members 165 and the touch pad decor 115 to press the elastic pressing members 165 in common.

As the common pressing plate 168 is provided, when a touch operation is input to the touch pad deco 115, the force applied during the touch operation may be transmitted to the plurality of elastic pressing members 165 through the common pressing plate 168. Therefore, the touch position and the touch pressure can be sensed based on this action. Thus, you can operate the pointer, or even enter letters or numbers.

On the other hand, as described above, the touch pad 120 is a part for inputting a touch operation such as operating a pointer or inputting a character that appears on the display screen. Character input may be performed by touching a finger on the upper surface of the touch pad 120 and moving the finger while looking at the screen.

In addition, the mode selection button 170 serves to select and execute a plurality of function-specific modes together with or independently of the touch pad 120.

In the present embodiment, as shown in FIG. 5, the plurality of function-specific modes include a mode change, a copy of the recognized character string to the browser search window, a deletion of the recognized character string, a search using a copied character string, and the like. And a pointing mode in which all changes, page downs, previous windows, page ups, and the like can be manipulated.

Both the writing mode for inputting a character by recognizing the detected coordinates caused by the touch pad 120 as an absolute position and the pointing mode used for pointing using a relative change amount of the detected coordinates may be implemented.

As described above, the write mode and the pointing mode may be performed through the mode selection button 170. In addition, in the present embodiment, the previous menu return, the volume down, the pause / playback, the mode selection button 170 may be performed. It is also possible to proceed with a media playback function that allows operations such as volume up.

In FIG. 5, various examples of operations by pressing the first to fourth mode selection buttons 170 provided in the remote controller according to the present embodiment are shown. Of course, the matter of FIG. 5 is only one example, and the scope of the present invention is not limited to the content of FIG. 5.

For example, when the mode selection button 170 is one or two, various kinds of menus may be executed by pressing the button once or two or more times, which is also within the scope of the present invention. Should belong.

Through the remote control of the present embodiment having such a configuration, web browsing may be executed as shown in FIG. 6, or a media player may be utilized as shown in FIG. 7.

7 is briefly described.

The user inputs a touch operation by touching the touch surface of the touch pad decor 115 while watching the pointer appearing on the display screen. That is, the pointing process is performed in the pointing mode.

Then, the controller (not shown) controls which touch pressure is input at which touch position. That is, the controller detects the amount or change in capacitance generated between the elastic body 150 and the electrode 145 as the driving part 153 of the elastic body 150 approaches the electrode 145, and then detects the capacitance. On the basis of the size or the amount of change of whether the input of the touch operation, the touch position or the touch pressure information is recognized.

Meanwhile, after the pointer operation according to the touch operation, if the touch pad decor 115 is touched strongly, the selected menu may be executed.

At this time, during execution of the selection menu, for example, when the first mode selection button 170 is pressed, the volume may be increased, and when the second mode selection button 170 is pressed, the volume may be decreased. When the third mode selection button 170 is pressed, the journal stop / play function is performed, and when the fourth mode selection button 170 is pressed, the previous menu may be returned.

Of course, if the mode selection button 170 is less than four, the volume increase function, the volume decrease function, the journal stop / play function, and the previous menu return function may be performed based on the number of times the corresponding button is pressed.

According to the present embodiment having the structure and operation as described above, since the program search or the Internet search can be performed without the keypad as shown in FIGS. 1 (b) and (c), the portability can be improved while reducing the weight or compactness of the remote controller In addition, by simplifying the input method of the user it is possible to significantly improve the operability and convenience than conventional.

More specifically, first of all, it is possible to input an essential character input when searching the Internet or a program by a remote controller implemented through the present invention without a keyboard-type keypad. That is, after inputting a character by touching a finger on the upper surface of the touch pad 120, the character may be moved while watching the screen.

As described above, in the case of the present invention, since a force-based technology is applied, character input is possible, but since the keypad of the keyboard type is not utilized, the number of buttons can be greatly reduced than before, and the remote control is lighter, improving portability and user input. The operation can be improved by simplifying the method.

In addition, it is possible to increase the convenience of the user by defining the buttons arranged around the touch pad 120 to be frequently used for each menu instead of a fixed purpose.

8 is a modified example according to the arrangement between the touch pad and the mode selection buttons.

The arrangement between the touch pad and the mode selection buttons may vary from the method of FIG. 2 as shown in FIGS. 8A to 8D.
