Also, the display unit 151 may be configured as a stereoscopic display unit 152 for displaying a stereoscopic image.

Here, a stereoscopic image represents a 3-dimensional stereoscopic image, and a 3-dimensional stereoscopic image represents a progressive depth and reality in which objects are located on a monitor or a screen, It is an image that makes you feel the same as the space. 3D stereoscopic images are implemented using binocular disparity. The binocular parallax means a parallax caused by the position of two eyes away from each other. When two eyes see two different images and the images are transmitted to the brain through the retina and fused, the depth and real feeling of the stereoscopic image can be felt .

The stereoscopic display unit 152 may be applied to a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system).

In addition, the 3D thumbnail image can generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and combine them to generate one 3D thumbnail image. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit 152 by a stereoscopic processing unit (not shown). The stereoscopic processing unit receives a 3D image and extracts a left image and a right image from the 3D image, or receives a 2D image and converts it into a left image and a right image.

On the other hand, when a display unit 151 and a sensor (hereinafter, referred to as 'touch sensor') that detects a touch operation form a mutual layer structure (hereinafter referred to as a 'touch screen' It can also be used as an input device in addition to the device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area where the touch object is touched on the touch sensor but also the pressure at the time of touch. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

If 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.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor 141 may be provided as an example of the sensing unit 140. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

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. When the touch screen is electrostatic, it is configured to detect the proximity of the pointer by a change of the electric field along the proximity of an object having conductivity (hereinafter, referred to as a pointer). In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch & The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, and the like). Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

In the case where the three-dimensional display unit 152 and the touch sensor have a mutual layer structure (hereinafter referred to as a 'three-dimensional touch screen') or a three-dimensional sensor that detects the touch operation and the stereoscopic display unit 152 are combined with each other The stereoscopic display unit 152 may also be used as a three-dimensional input device.

The sensing unit 140 may include a proximity sensor 141, a three-dimensional touch sensing unit 142, an ultrasonic sensing unit 143, and a camera sensing unit 144 as an example of the three-dimensional sensor.

The proximity sensor 141 measures the distance between the sensing surface (for example, a user's finger or a stylus pen) to which the touch is applied without mechanical contact using the force of the electromagnetic field or infrared rays. The terminal recognizes which part of the stereoscopic image has been touched using the distance. In particular, when the touch screen is of the electrostatic type, the proximity of the sensing object is detected by a change of the electric field according to the proximity of the sensing object, and the touch on the three-dimensional is recognized using the proximity.

The stereoscopic touch sensing unit 142 senses the strength or duration of a touch applied to the touch screen. For example, the three-dimensional touch sensing unit 142 senses a pressure to apply a touch, and when the pressing force is strong, recognizes the touch as a touch to an object located further away from the touch screen toward the inside of the terminal.

The ultrasonic sensing unit 143 is configured to recognize the position information of the sensing target using ultrasonic waves.

The ultrasound sensing unit 143 may include, for example, an optical sensor and a plurality of ultrasound sensors. The light sensor is configured to sense light, and the ultrasonic sensor is configured to sense ultrasonic waves. Since light is much faster than ultrasonic waves, the time it takes for light to reach the optical sensor is much faster than the time it takes for the ultrasonic waves to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to sense a touch of a sensing target with respect to a three-dimensional stereoscopic image. When the distance information detected by the laser sensor is added to the two-dimensional image photographed by the camera, three-dimensional information can be obtained.

As another example, a photosensor may be stacked on a display element. The photosensor is configured to scan the movement of the object 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 light change, thereby acquiring position information of the object to be sensed.

The alarm unit 154 may output a signal for notifying the occurrence of an event by using a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the sound output module 153 so that the display unit 151 and the sound output module 153 may be classified as a part of the alarm unit 154 .

The haptic module 155 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 155 may be vibration. The intensity and pattern of the vibration generated by the hit module 155 can be controlled by the user's selection or setting of the control unit. For example, the haptic module 155 may combine and output different vibrations or sequentially output the vibrations.

The first case 103, together with the window 102, is a portion of the portable terminal 100, which is easy to contact with the outermost object, and can be formed of a metal material so as to minimize wear and scratches. Further, The case 103 may be formed to be conductive to extend the ground of the antenna 200 described later. Also, the first case 103 may be implemented as a 'ornament' existing on the surface of the 'case', in addition to a substantial role of 'case'.

Meanwhile, the second case 104 is formed of a dielectric material to smoothly induce the radiation of the antenna 200. The second case 104 may be formed of resin or the like which is easy to form a complicated internal shape.

Apparently, the second case 104 includes a side 104a that is inclined so as to form a smooth side appearance from the window 102, and a third case 105 Is formed to be conductive so as to form the main ground of the antenna 200. The third case 105 may include a removable cover 106 for inserting a SIM card or the like.

In order to transmit images or images in the watch-type mobile terminal, higher data transmission / reception performance is required. Accordingly, an antenna capable of exhibiting improved efficiency with a smaller size is being considered.

In the case of a watch-type mobile terminal, the band itself may be used as a radiator of an antenna or a radiator may be inserted into the band. In this case, a thin metal plate may be exposed to the outside or a thin metal plate may be inserted into the band. It is subject to a lot of design constraints.

The watch-type mobile terminal described in the following embodiments relates to a method of utilizing a metal thread formed along a rim of a non-metallic band as a radiator of an antenna. As a result, an improved antenna performance can be achieved while having the advantages of an external antenna.

FIGS. 4 to 7 are conceptual diagrams illustrating examples of a metal thread operating as a radiator of an antenna in the watch mobile terminal 100 according to the embodiments of the present invention.

As shown in FIGS. 4 to 7, the watch mobile terminal 100 includes a case 103 and 104, a nonmetal band 107, a metal thread 210, and a power feeder 290.

Various devices including the display portion 151 may be formed in the cases 103 and 104. [ The cases 103 and 104 may be formed of a synthetic resin or a metal member, and at least a part of them may be formed of a metal member.

The band is formed of a non-metallic member, and examples of the non-metallic member include rubber, natural leather or artificial leather. The non-metal band 107 may have a shape in which the first member 107a (see FIG. 8) formed at the upper portion and the second member 107b (see FIG. 8) formed at the lower portion are overlapped with each other. That is, the first member 107a and the second member 107b may be stacked on each other. Further, another metal member or nonmetal member may be inserted between the first member 107a and the second member 107b.

The metal thread 210 has a thin thread shape and is formed along the rim of the non-metal band 107. As a result, the appearance of the nonmetal band 107 can be improved.

The metal thread 210 is formed of a conductive member and can operate as a radiator of the antenna when being fed by the power feeder 290.

The metal thread 210 may join the first member 107a and the second member 107b, which are stacked on each other. For this, the first and second members 107a and 107b may be stacked on each other so that the first and second members 107a and 107b may be stacked.

Alternatively, when the non-metallic band 107 is formed of one member that is not laminated, the metal thread 210 may be simply an ornamental pattern formed along the rim of the non-metallic band 107. Even in this case, it is possible to operate as a radiator of the antenna by feeding the power feeder 290.

Also, the metal thread 210 may be formed along the rim of any one member in a state where the first and second members 107a and 107b are stacked on each other.

The feeding part 290 is a part for supplying a current to the metal thread 210 operating as a radiator, and may be configured by a combination of a balun, a phase shifter, a divider, an attenuator, and an amplifier. The power feeder 290 may be formed inside the case 103, 104.

As described above, the antenna device including the power feeder 290 and the metal thread 210 may be a PIFA, a folded dipole, or a Monopole type antenna device.

Since the metal thread 210 operates as a radiator of the antenna device, the length of the metal thread 210 may be varied to form a resonance at a specific frequency according to the characteristics of the antenna device according to each type. That is, the metal thread 210 may be continuously connected along the rim of the nonmetal band 107 or may be short-circuited at a predetermined interval so as to have a predetermined length.

Referring to FIG. 5, the watch-type mobile terminal 100 may include a plurality of antenna devices. Each of the antenna devices ANT1 and ANT2 may be configured to transmit and receive signals of different frequency bands and may be configured to transmit and receive signals (data signals, MIMO, etc.) of the same frequency band.

For example, the first antenna device ANT 1 may be formed to transmit and receive signals of the DCN 1x scheme or the PCS 1x scheme, and the second antenna device ANT 2 may be formed of a DCN EVDO (Evolution-Data Optimized or Evolution- Data Only) system.

In addition, when the first antenna apparatus ANT 1 transmits / receives a signal conforming to the LTE B4 scheme, the second antenna apparatus ANT 2 can be formed to transmit / receive signals conforming to the LTE B13 scheme.

Alternatively, when the first antenna device ANT 1 transmits / receives a signal corresponding to the voice service of the mobile terminal, the second antenna device ANT 2 may be configured to transmit / receive a data signal corresponding to the LTE service of the mobile terminal have.

Metal threads 210 and 210 'may be formed to operate as a radiator in each antenna device. Also, the metal threads 210 and 210 'may be spaced apart from each other in the diagonal direction. For example, a first metal thread 210 may extend left down from the case 103, 104, and a second metal thread 210 'may extend upwardly. As a result, the isolation characteristics between the antennas can be improved. Feed parts 290 and 290 'feed respective metal threads 210 and 210'.

Referring to FIG. 6, the watch-type mobile terminal 100 may include a min- The reason for putting the meandering portion 230 is to resonate the metal thread 210 at a lower frequency within a limited space. Further, by providing the meandering portion 230, the antenna characteristic can be further improved. That is, it is possible to change the resistance value, which is the real number of the impedance, or the reactance value, which is the imaginary number, through the patterns constituting the medium 230.

Referring to FIG. 7, the metal thread 210 '' may include a first line 217 and a second line 218.

The first line 217 may be a line extending from the power feeder 290 by a predetermined length and the second line 218 may be a line branched from the first line 217. When resonating at the first frequency due to the first line 217, the second line 218 may be configured to resonate at a second frequency adjacent to the first frequency. Additional resonance occurs at the adjacent frequencies, which may improve bandwidth.

8-10 are cross-sectional views illustrating embodiments of a non-metallic band 107 having a metal thread 210. FIG. FIGS. 8 to 10 show examples in which the metal thread 210 is formed when the non-metal band 107 is formed by stacking the first and second members 107a and 107b together.

8 to 10, an annular portion 107d having a hole may be formed on the upper portion of the nonmetal band 107. [ The hinge unit 109 can be inserted through the hole of the hook 107d. As a result, the non-metal band 107 and the case 103, 104 can be combined.

The non-metallic band 107 may be divided into a first band and a second band, and a fastener may be formed at a lower portion of the first band. An insertion hole in which the protrusion of the buckle is inserted corresponding to the fastener may be formed in the lower portion of the second band.

Referring to FIG. 8, the metal thread 210 may join the first member 107a and the second member 107b, which are stacked on each other. For this purpose, the metal thread 210 can hold the first and second members 107a and 107b with the first and second members 107a and 107b stacked on each other.

At this time, the insulating portion 107c may be formed so that the metal thread 210 and the wrist do not contact each other. The insulating portion 107c may be formed to cover the metal thread 210 exposed on one side of the second member 107b. That is, when the insulating portion 107c is exposed and comes into contact with the human body, the insulating portion 107c may be formed to cover the exposed metal thread 210 because it may affect the antenna characteristics.

9, a metal thread 210 is formed along the rim of the first member 107a and another member 260 (not shown) is electrically connected to the metal thread 210 along the rim of the second member 107b May be formed. That is, the metal thread 210 may be formed along the edge of the first member 107a that does not contact the wrist. Thus, it is possible to prevent the metal thread 210 from coming into contact with the human body.

Then, the first and second members 107a and 107b, which are not coupled to each other, can be coupled to each other by an adhesive or another adhesive member 107e such as a double-sided tape.

Fig. 10 shows an example in which another conductive member is formed between the first and second members 107a and 107b. At this time, the metal thread 210 can join the first member 107a and the second member 107b stacked together, and the metal thread 210 can be connected to the conductive member at any one point. The conductive member may be, for example, the above-described meander part 230.

Referring again to Fig. 3, first and second projections 104a and 104b are formed on both sides of the case 103 and 104, respectively. The ring 107d of the nonmetal band 107 is accommodated between the first and second projections 104a and 104b and the hinge unit 109 is arranged to penetrate through the hole of the ring 107d. The hinge unit 109 is inserted into the first and second protrusions 104a and 104b at both ends thereof in a state where the hinge unit 109 has passed through the loop 107d. At this time, the non-metal band 107 is coupled to the case 103, 104 through the hinge unit 109. The metal thread 210 formed on the non-metal band 107 is inserted into the case 103, 104, A structure for supplying power using the power supply 290 will be described below.

Figs. 11 to 14 are conceptual diagrams showing examples of the power feeder 290 for feeding the metal thread 210. Fig.

Referring to Fig. 11, a feed part 290 may be formed close to the projections 104a and 104b of the case 104. Fig. The feeding part 290 is electrically connected to the hinge unit 109 by the feed line 291 and one end of the metal thread 210 is brought into contact with the hinge unit 109. Thus, the feeding part 290 and the metal thread 210 are directly connected through the hinge unit 109. [

12, a feeding part 290 is formed close to the projecting parts 104a and 104b of the case 104 and the feeding part 290 is electrically connected to the hinge unit 109 and the feeding line 291 .

However, an extension 211 is formed at one end of the metal thread 210 connected to the hinge unit 109. The extension 211 is formed parallel to the hinge unit 109 so that the metal thread 210 can be capacitive coupling feed (CCF) by the hinge unit 109.

Due to the capacitive coupling feeding, the value of the capacitive reactance of the antenna can be increased. Increasing the value of the capacitive reactance reduces the resonant frequency because the input impedance due to the capacitance is inversely proportional to the frequency. The fact that the resonant frequency is reduced means that the antenna device includes a capacitive coupling so that it can operate in a lower frequency band with a shorter length. That is, when the antenna device includes capacitively coupled members, the antenna device can operate in a lower frequency band in a narrower space.

Referring to FIG. 13, a feed part 290 may be formed adjacent to the protrusions 104a and 104b of the case 104. FIG.

The feed part 290 may be electrically connected to the first contact 292 exposed to one side of the case 103 or 104 by the feed line 291. The second contact 212 may be formed on one side of the metal thread 210 corresponding to the first contact 292. The first contact 292 and the second contact 212 can be in direct contact with each other. The first contact 292 may be disposed between the protrusions 104a and 104b.

The second contact 212 may be formed to extend along the outer periphery of the ring 107d. Therefore, even if the ring 107d rotates, the contact between the first contact 292 and the second contact 212 can be maintained.

Referring to Fig. 14, the power feeder 290 may be formed adjacent to the protrusions 104a and 104b of the case 104. Fig. The feed part 290 may be electrically connected to the first contact 293 exposed to one side of the case 103 or 104 by the feed line 291. The first contact 293 may be disposed between the protrusions.

The second contact 213 may be formed on one side of the metal thread 210 corresponding to the first contact 293. The second contact 213 may be formed parallel to the first contact 293 so that the metal thread 210 connected to the second contact 213 is coupled to the first contact 293 by a first contact 293, .

The above-described watch mobile terminal is not limited to the configuration and method of the above-described embodiments, but the embodiments may be modified such that all or some of the embodiments are selectively combined so that various modifications can be made. .
