Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be, for example, a finger, a stylus, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

Whereby the stylus 200 can be moved with the terminal body.

Hereinafter, the stylus 200 will be described in more detail with reference to FIGS. 4 and 5. FIG.

FIG. 4 is a perspective view showing an example of the stylus 200 shown in FIG. 3, and FIG. 5 is a sectional view taken along line V-V shown in FIG.

4 and 5, a first contact portion 201a and a second contact portion 201b may be provided on an outer circumferential surface of the body 201. [ The first contact portion 201a and the second contact portion 201b are portions that can be contacted when the user holds the stylus 200. As will be described later, Lt; / RTI >

The first contact portion 201a and the second contact portion 201b may be disposed along the longitudinal direction of the body portion 201. As shown in FIG. The first contact portion 201a and the second contact portion 201b may be spaced apart from each other at a predetermined interval. However, the present invention is not limited thereto. The first contact portion 201a and the second contact portion 201b may be disposed along the circumference of the body 201 or continuously.

The first and second contact portions 201a and 201b may be formed of a metal material and may be integrally formed with the body portion 201 by double injection molding. The body portion 201 may be formed of synthetic resin, have.

The first and second contact portions 201a and 201b may be formed to form the same surface as the outer circumferential surface of the body portion 201. [ Alternatively, the first and second contact portions 201a and 201b may be formed so as to protrude from the outer circumferential surface of the body portion 201 so that the user can make contact using a tactile sense.

A tip portion 210 is provided at one end of the body portion 201. The tip portion 210 is disposed so as to protrude outward from one end of the body portion 201. The tip portion 210 is a portion where the user directly touches the touch screen when the stylus 200 is used. The tip portion 210 may be formed of an elastic material to mitigate the impact when the touch screen is touched.

The tip portion 210 is connected to the body portion 201 so that the electric charge flowing through the touch screen flows to the body of the user holding the body portion 201 when the tip portion 210 touches the touch screen.

In addition, the tip portion 210 is connected to the first and second contact portions 201a and 201b, respectively. Specifically, the first contact portion 201a is connected to the tip portion 210 through the first connection portion 220, and the second contact portion 201b is connected to the tip portion 210 through the second connection portion 230 .

The first and second connection portions 220 and 230 include materials having different dielectric constants. The change in capacitance is related to the permittivity. Accordingly, when the tip portion 210 touches the touch screen, different capacitance changes may be generated for each contact point, and the touch screen distinguishes the change of the electrostatic capacitance, Signal.

The body 201 may also be formed of a material having a dielectric constant different from that of the first and second connection portions 220 and 230. In this case, if the tip portion 210 touches the touch screen while the stylus 200 is held by the user without touching the first and second contact portions 201a and 201b, the first and second contact portions 201a , 201b may be generated that is different from the case where at least one of them is contacted.

The first and second connection portions 220 and 230 may be formed by sealing the dielectric bodies 222 and 232 in the connection cases 221 and 231 and then sealing them. The connection case 221 is connected to the first contact part 201a and the tip part 210 and forms a built-in space which is sealed to the outside. The built-in space may be filled with a dielectric material 222 made of a fluid or powder having a high dielectric constant. As such a dielectric material 222, a material having a high dielectric constant such as water, alcohol, acetone, and ceramic powder may be used.

Alternatively, the first and second connection portions 220 and 230 may be formed of a material having a high dielectric constant without being connected to the connection cases 221 and 231. For example, the first and second connection portions 220 and 230 may be formed of a ceramic material having a specific shape.

6 is a cross-sectional view showing a modified example of the stylus 200 shown in FIG.

Referring to the drawing, the first connection part 220 'connects the first contact part 201a' and the tip part 210 '. The first connection part 220 'is formed on the outer circumferential surface of the body part 201' and the tip 210 'is provided at one end of the body part 201' in the longitudinal direction. May be formed in a bent shape at least at one point.

The second connection part 230 'may be branched from a part of the first connection part 220' and connected to the second contact part 201b '. In this case, it is preferable that the dielectric material included in each of the first and second connection portions 220 'and 230' is formed of a material that is not mixed with each other. For example, the first and second connection portions 220 'and 230' may be formed of a rigid ceramic material having a specific shape.

According to the above structure, when the tip 210 'touches the touch screen in a state where the first contact 201a' is in contact, the change in capacitance is related to the dielectric material provided in the first connection 220 ' do. Meanwhile, when the tip portion 210 'touches the touch screen in a state that the second contact portion 201b' is in contact, a change in capacitance is caused by a change in the dielectric constant of the first and second connection portions 220 'and 230' It is related to matter. That is, in the above two cases, a different capacitance change may be generated. It goes without saying that another capacitance change can be generated in a state in which the user does not touch both the first and second contact portions 201a 'and 201b'.

Hereinafter, examples of the user interface using the stylus 200 shown in Fig. 4 will be described with reference to Figs. 7 to 9. Fig.

As described above, when the tip portion 210 of the stylus 200 touches the touch screen (an example of the display portion 151), the change in capacitance generated on the touch screen is caused by the body portion 201, 1 contact portion 201a and the second contact portion 201b are contacted with each other. This is because the dielectric constant varies depending on the portion to be contacted.

The touch screen converts this capacitance change into an electrical input signal, and the control unit 180 (see FIG. 1) is configured to process the input signal. The mobile terminal 100 distinguishes the change in the electrostatic capacity generated on the touch screen according to the portion to be contacted when the tip portion 210 touches the touch screen and performs different control commands according to the contact portion .

7A to 7C are conceptual diagrams showing that the image information displayed on the touch screen is changed according to the portion to which the tip 210 touches when touching the touch screen. 7A shows a state in which the body 201 is in contact when the tip 210 touches the touch screen and FIG. 7B shows a state in which the first contact 201a is in contact with the tip when the tip 210 touches the touch screen. And FIG. 7C shows a state in which the second contact portion 201b is in contact when the tip portion 210 touches the touch screen.

As shown in FIG. 7A, when the body 201 is contacted when the tip 210 touches the touch screen, the first image information (thin line in this figure) may be displayed on the touch screen. This may be the same image information as when the user directly touches the touch screen without using the stylus 200. [ That is, when the user directly touches the touch screen and when the user touches the tip portion 210 with the body portion 201 of the stylus 200 in contact with the touch screen, Command. Of course, different control commands may be performed by distinguishing the above two cases.

7B, if the first contact portion 201a is contacted when the tip portion 210 touches the touch screen, second image information (a line having a medium thickness in the drawing) is displayed on the touch screen . As shown in FIG. 7C, when the second contact portion 201b is contacted when the tip portion 210 touches the touch screen, third image information (a thick line in the drawing) may be displayed on the touch screen .

8A to 8C are conceptual diagrams showing that the image information displayed on the touch screen changes when the first and second contact portions 201a and 201b are successively contacted when the tip portion 210 touches the touch screen.

The touch screen may generate an input signal different from the input signal described above when the first and second contact portions 201a and 201b are in turn contacted when the tip portion 210 touches the touch screen. At this time, based on the order in which the first and second contact portions 201a and 201b are in contact, the touch screen distinguishes the input signal as the first sub input signal and the second sub input signal corresponding to functions opposite to each other .

8A, when the tip portion 210 touches the touch screen as shown in FIG. 8B, the first contact portion 201a is contacted with the second contact portion 201b, The image information can be zoomed in. Conversely, when the tip portion 210 touches the touch screen, as shown in FIG. 8C, when the first contact portion 201a is contacted after the second contact portion 201b is contacted, the image information is reduced out.

In the above two cases, the controller 180 may enlarge or reduce the image information around the point where the tip 210 is touched.

On the other hand, the control unit 180 may display the image information contrary to the example illustrated in the figure. For example, if the tip portion 210 touches the touch screen and the second contact portion 201b is contacted after the first contact portion 201a is contacted, the image information may be zoomed out have.

9 shows a case where the first and second contact portions 201a and 201b are contacted together when the tip portion 210 touches the touch screen. In this case, the touch screen can generate an input signal different from the input signal described above have.

In this figure, when the first and second contact portions 201a and 201b are contacted together when the tip portion 210 touches the touch screen, the control portion 180 can capture the screen information displayed on the touch screen and store the screen information in the album have. At this time, the controller 180 can give a visual effect to the touch screen so that the user can know that the first and second contact portions 201a and 201b are all contacted and the capture function is performed. For example, the touch screen may display a concentric scanning line S about a point at which the tip 210 is touched.

The tip portion 410 and the pushing portion 440 are configured to be capable of being drawn into and drawn out from the body portion 401, respectively. That is, when the body portion 401 is pressed toward the touch screen in a state where the tip portion 410 is in contact with the touch screen, the tip portion 410 is drawn into the body portion 401. Further, the pushing operation portion 440 can be pulled into the body portion 401 by the user's pressing operation.

The first connection portion 420 is disposed between the tip portion 410 and the pushing portion 440 and is configured to be connected to the dielectric portion 410a of the tip portion 410 when the tip portion 410 is inserted. The second connection part 430 is provided in the pushing part 440 and is connected to the first connection part 420 when the pushing part 440 is pushed.

As shown in the figure, the first connection part 420 may be disposed to cover the inner wall of the body part 401 and extend along the longitudinal direction. When the tip portion 410 and the pushing portion 440 are drawn into the body portion 401, the dielectric portion 410a and the second connection portion 430 of the tip portion 410 are connected to each other through a first connection portion 420 .

An intermediate member 450 may be disposed between the tip 410 and the pushing portion 440 and includes at least a portion of the first connection 420. A first elastic member 460 may be disposed between the tip portion 410 and the intermediate member 450 to elastically press the tip portion 410 in the direction in which the tip portion 410 is drawn out. A second elastic member 470 may be disposed between the pressing portion 440 and the intermediate member 450 to elastically press the pressing portion 440 in the direction in which the pressing member 440 is drawn out.

The first and second connection portions 420 and 430 include materials having different dielectric constants. The change in capacitance is related to the permittivity. Accordingly, when the tip portion 410 touches the touch screen, different capacitance changes may be generated depending on the pull-in or pull-out states of the tip portion 410 and the pushing portion 440.

Specifically, when the tip portion 410 is drawn into the body portion 401, the dielectric portion 410a of the tip portion 410 contacts the first connection portion 420, and the pushing operation portion 440 contacts the inside of the body portion 401 The second connection unit 430 is brought into contact with the first connection unit 420. When both the tip portion 410 and the pushing portion 440 are drawn into the body portion 401, the first connection portion 420 is brought into contact with the dielectric portion 410a and the second connection portion 430 of the tip portion 410 do. The touch screen can distinguish changes in capacitance caused by this situation and convert them into different electrical input signals.

12A and 12B, the stylus 500 includes a body portion 501, a tip portion 510, and a connection portion 520.

At least one contact portion may be provided on the outer circumferential surface of the body portion 501. For example, the first contact part 501a and the second contact part 501b may be provided on the outer circumferential surface of the body part 501. [ Hereinafter, the first and second contact portions 501a and 501b will be described by way of example, but the present invention is not limited thereto, and the contact portions may be provided in various numbers.

The first contact portion 501a and the second contact portion 501b are portions in which a user's finger is contactable when the user holds the stylus 500. The first contact portion 501a and the second contact portion 501b have different capacitances Can be generated.

The first and second contact portions 501a and 501b may be spaced apart from each other at various positions of the body portion 501 as described above with reference to FIG.

Meanwhile, as shown in the figure, the first contact portion 501a and the second contact portion 501b may have different areas. That is, the stylus 500 according to an embodiment of the present invention can change the duration of the capacitance change due to the difference in area of the first and second contact portions 501a and 501b.

Specifically, when the user's finger touches the outer peripheral surface of the body portion 501 at a constant speed along one direction, the area of the first and second contact portions 501a and 501b is different from each other, The duration of contacting the first and second contact portions 501a and 501b may be varied. Thus, the stylus 500 can change the duration of the change of the capacitance.

The connection part 520 may connect the first and second contact parts 501a and 501b to the tip part 510. [ At this time, since the connection part 520 includes the dielectric 522, it is possible to transmit a change in the capacitance caused by the touch to the first and second contact parts 501a and 501b to the tip part 510 have.

When touches are sequentially applied to the contact portions 501a and 501b, the touch screen displays the difference in the duration of change in capacitance caused in such a situation (i.e., when the first and second contact portions 501a and 501b are touched Time difference) can be distinguished and converted into different electrical input signals.

For example, as shown in FIG. 12C, the touch screen may sense a time when a change in capacitance is detected. More specifically, when a touch is applied to the first contact portion 501a, the duration of the change in capacitance is sensed during the first time interval (530 or a section), and the touch is applied to the second contact portion 501b The duration of the change in capacitance during the second time period (540 or b) may be sensed.

The connection unit 520 may be fabricated by placing the dielectric 522 in the connection case 521 and then sealing the same. In addition, the dielectric 522 may be made of a material having a dielectric constant.

As described above, the connection part 520 may be formed in its own shape without the connection case 521, and may be formed of a material having a high dielectric constant.

Meanwhile, the connecting portion 520 of the stylus 500 according to an embodiment of the present invention may be made of a material having the same permittivity for each of the first and second contact portions 501a and 501b. However, the present invention is not limited thereto, but may be made of a material having a different dielectric constant for each of the first and second contact portions. In this case, the touch screen can sense at least one of the change of the duration of the capacitance and the change of the permittivity, and it is possible to detect various types of electrical input signals. For example, a touch screen can sense an electrical input signal by using a change in the duration of capacitance and a change in permittivity.

The stylus 300, 400, 500 according to another embodiment of the present invention may also provide a user interface using various signals as described above with reference to FIGS.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
