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 reality space. 3D stereoscopic images are implemented using binocular disparity. The binocular parallax means the parallax caused by the positions of the two separated eyes. When the two eyes see different two-dimensional 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 do.

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 measures the presence or absence of an object approaching a predetermined sensing surface It refers to a sensor that uses infrared rays to detect without mechanical contact. 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 fluorescent light sensor, a mirror reflection fluorescent light sensor, a high frequency oscillation 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 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.

Hereinafter, the internal structure of the mobile terminal 200 will be described in more detail.

FIG. 3 is an exploded perspective view of the mobile terminal 200 shown in FIGS. 2A and 2B.

Referring to FIG. 3, a printed circuit board (PCB) 280 is embedded in the terminal body. The printed circuit board 280 may be mounted to, for example, the front case 201 or the rear case 202, or may be mounted on a separate structure. The separate structure may be a middle case (not shown). Hereinafter, a structure in which the front case 201 and the rear case 202 are separately provided will be described as an example, but the present invention is not limited thereto, and the cases 201 and 202 may be integrally formed.

The printed circuit board 280 is configured as an example of a control unit 180 (see FIG. 1) for operating various functions of the mobile terminal 200. A plurality of the printed circuit boards 280 are provided and may perform the function of the control unit 180 (see FIG. 1) by mutual combination.

The rear case 202 and the battery cover 203 may have through holes 202a and 203a corresponding to the rear input unit 233, respectively.

A connector 281 for electrically connecting an electronic component (not shown) to the printed circuit board 280 is mounted on the printed circuit board 280. The connector 281 electrically connects electronic components of a size that can not generally be directly mounted on the printed circuit board 280 with the printed circuit board 280. The electronic component includes a flexible printed circuit board (not shown) for electrically connecting another printed circuit board (not shown), a microphone 222, or the like to the printed circuit board 280, Not shown) and the like. However, the present invention is not limited thereto, and any electronic component may be used as long as it requires electrical connection with the printed circuit board 280.

The connector 281 is formed so that at least a part thereof is bent and is divided into two parts about the bent part. When the connector 281 is pressed on both sides by the printed circuit board 280 and the electronic part approaching the printed circuit board 280, the two divided parts of the connector 281 are brought close to each other, The elastic member is elastically deformed. Accordingly, the connector 281 can maintain contact with the printed circuit board 280 and the electronic component.

Hereinafter, the specific structure of the connector will be described with reference to Figs. 4 to 11. Fig.

4 is an enlarged perspective view of the connector 281 shown in Fig.

The connector 281 includes a bonding portion 281a, a contact portion 281b, an elasticity providing portion 281c, and a rigidity beam portion 281d.

The adhesive portion 281a extends in a direction parallel to one surface of the printed circuit board so as to be adhered to the printed circuit board 280 (see Fig. 3). Adhesive 281a is bonded to a predetermined mounting area of the printed circuit board by Surface Mounting Technology (SMT) including soldering.

The contact portion 281b has a region 281b 'connected to the adhering portion 281a and extending in a direction opposite to the extending direction of the adhering portion 281a. The contact portion 281b is projected and bent in the extending process so that at least a portion thereof is pressed by an electronic component (not shown) approaching the printed circuit board.

The elastic supporter 281c is bent at least in part so as to provide an elastic force to the contact portion 281b pressed by the electronic component to connect the contact portion 281b and the adhesive portion 281a. The end of the adhesive portion 281a and the end of the contact portion 281b are spaced apart from each other and the adhesive portion 281a and the contact portion 281b are formed so as to be divided into two halves based on the elastic material supply 281c.

When the contact portion 281b is pressed by the electronic component approaching the printed circuit board in a state where the adhesive portion 281a is bonded to the printed circuit board, the elastic member 281c is pressed against the contact portion 281b by the bending shape, And the contact portion 281b can also press the electronic component to maintain contact with the electronic component by reaction against the action applied to the contact portion 281b in the electronic component.

The rigid beam guiding portion 281d is formed between the bonding portion 281a and the elastic support portion 281c or between the contact portion 281b and the elastic support portion 281c. The rigid beam guiding portion 281d is at least partially bent and bent so as to prevent plastic deformation of the elastic material supplying portion 281c. In Fig. 4, the rigid beam guiding portion 281d is shown to be formed between the bonding portion 281a and the elastic support portion 281c.

The rigid supporting beam portion 281d is connected to the region 281b 'where the contact portion 281b extends and the bonding portion 281a' As shown in FIG. The rigidity-imparting beam portion 281d and the elasticity providing portion 281c may be formed to bend continuously. For example, as shown in Fig. 4, the rigid beam guiding portion 281d connected to the bonding portion 281a protrudes in the extending direction of the bonding portion 281a, and at least one region can be bent and bonded to the printed circuit board again Return to the position. The return portion of the rigid-beam guiding steel portion 281d is bent again to be connected to the elastic feeder 281c and the elastic feeder 281c is also bent to be connected to the extended region 281b 'of the contact portion 281b.

The case where the contact portion 281b is pressed by the electronic component and the case where there is the rigidity beam portion 281d is compared with the case where the contact portion 281b is not pressed. stress decreases. The fact that the stress of the elasticity providing member 281c is reduced means that the resistance generated by the connector 281 is reduced, thereby improving the rigidity. Therefore, the rigid-beam-guiding steel portion 281d can prevent plastic deformation of the connector 281. [

The rigid beam guiding portion 281d is bent in the space between the extending portion of the contact portion 281b and the adhering portion 281a so that it does not interfere with other components protruding outward or mounted on the printed circuit board. Therefore, the connector 281 including the rigid-beam-guiding steel portion 281d has an advantage that the rigidity can be ensured without increasing the thickness and dimension of the connector 281 in the same mounting space of the printed circuit board.

5 is a perspective view showing a connector 381 of a different form from that of FIG.

The connector 381 includes the bonding portion 381a, the contact portion 381b, the elasticity providing portion 381c and the rigid beam protecting portion 381d. Unlike the connector 281 shown in Fig. 4, the connector 381 includes the connector 381 The rigid beam guiding portion 381d is formed between the abutting portion 381b and the elastic supporting portion 381c. The rigid beam protecting portion 381d is connected to the region 381b 'where the contact portion 381b extends and the bonding portion 381a', 381b ' As shown in FIG. The rigidity-imparting beam portion 381d and the elastic support portion 381c may be formed to bend continuously.

In the case where the contact portion 381b is pressed by an electronic component (not shown) as compared with the case where the rigid-beam-guiding steel portion 381d is provided, ) Becomes smaller. The fact that the stress of the elasticity providing member 381c is reduced means that the resistance generated by the connector 381 is reduced, thereby improving the rigidity. Therefore, the rigid-beam-guiding steel portion 381d can prevent plastic deformation of the connector 381. [

The rigidity of the connector without rigid reinforcement, the connector 281 shown in Fig. 4 and the connector 381 shown in Fig. 5 can be compared with each other with reference to Figs. 6A to 6C and Table 1.

FIG. 6A shows a connector without a rigid reinforcement, FIG. 6B shows the connector 281 of FIG. 4, and FIG. 6C shows the connector 381 of FIG.

The images are simulated when the connector is pressed by the electronic component, and the stresses of the connectors are compared with each other to show different colors. Simulation results show that the smaller the stress is, the closer to blue, and the larger the stress, the closer to red.

As can be seen from Figs. 6A to 6C, the maximum stressed portion of each connector is the elastic material shown in red. The maximum stresses of the elasticity providing portions in Figs. 6A to 6C can be compared as shown in Table 1 below.

division stress (von Mises, N / mm ² ) Connector without elastic reinforcement About 554.3 4, About 412.2 5, About 506.7

The bead 481e extends the area of the elastic member 481c to prevent the stress of the elastic member 481c from concentrating and to reinforce the rigidity of the elastic member 481c. The bead 481e may be formed to protrude toward the stiffening steel portion 481c, and at least a part of the bending portion of the elastic member 481c may be recessed when viewed from the opposite side.

The connector 581 shown in Fig. 8 has the same configuration as the connector 481 of Fig. 7 except that the beads 581e 'and 581e "are further added. The connector 681 shown in Fig. 9 Has a shape in which the bead 681e extends from the elastic member 681c to the region 681b 'where the contact portion 681b extends.

The connectors 581 and 681 shown in Figs. 8 and 9 have a structure in which the number and area of the beads 581e ', 581e ", and 681e are respectively enlarged as compared with the connector 481 shown in Fig. The connectors 581 and 681 of the structure can further reinforce the rigidity of the elastic supporters 581c and 681c as compared with the connector 481 shown in Figure 7. The beads 481e and 581e ' The number and area can be selectively determined according to the size of the connectors 481, 581, 681 and the use of the connectors 481, 581, 681.

The number of protrusions 781f ' May be selectively determined depending on the size of the connector 781 and the use of the connector 781. [

Hereinafter, a connector including a deformation preventing portion formed to prevent plastic deformation of the connector will be described.

11A is a perspective view of the connector 881 including the deformation preventing portion 881g, and FIG. 11B is a sectional view taken along line A-A of FIG. 11A.

The deformation preventing portion 881g is formed to prevent plastic deformation of the connector 881 due to an external force or an impact during the process of mounting the connector 881 on the printed circuit board or during the process of assembling the mobile terminal or using the mobile terminal do.

The deformation preventing portion 881g includes a side wall 881g ', a front wall 881g' 'and a rear wall 881g' '.

The side wall 881g 'extends from the adhering portion 881a toward the contact portion 881b to cover the side surface of the contact portion 881b to prevent the contact portion 881b and the adhesive portion 881a from being plastically deformed in mutually opposite directions. For example, the side circle may be formed to surround both sides of the contact portion 881b. The side wall 881g prevents the adhering portion 881a and the contact portion 881b from spreading in different directions when an external force of different directions is applied to the adhering portion 881a and the contacting portion 881b, respectively.

The front wall 881g "extends from the adhesive portion 881a or the side wall 881g 'to prevent the contact portion 881b and the adhesive portion 881a from being brought into contact with each other by plastic deformation, The front wall 881g " is shown extending from the side wall 881g 'to both sides of the side wall 881g'. The front wall 881g "can prevent the external force from being transmitted to each end of the adhesive portion 881a and the contact portion 881b even when an external force is applied in the direction in which the front wall 881g" is formed.

The rear wall 881g '' encloses the extended region 881b 'of the contact portion 881b to prevent the adhesive portion 881a and the contact portion 881b from being separated from each other by the plastic deformation of the elasticity providing portion 881c. The rear wall 881g "'may be formed to extend from the side wall 881g' to both, as shown. The rear wall 881g "'restricts the elastic deformation range of the contact portion 881b so that the contact portion 881b can be prevented from moving away from the adhesion portion 881a by an external force.

Referring to Fig. 11B, the distance H between the end of the contact portion 881b and the end of the adhesion portion 881a is shown. When the contact portion 881b is pressed by the electronic component, the connector 881 is elastically deformed by the elastic member 881c to maintain contact with the electronic component. However, as the electronic component approaches the printed circuit board, ) May be plastically deformed. Particularly, when the distance H between the adhering portion 881a and the contact portion 881b is formed farther than necessary, the connector 881 is more likely to be plastically deformed beyond the range of elastic deformation as the electronic component is closer to the printed circuit board The possibility increases.

The present invention is characterized in that the end of the contact portion 881b pressed by the electronic component is in contact with the end of the contact portion 881b spaced apart from each other so as to come into contact with the adhesion portion 881a before plastic deformation of the elastic member 881c, Is set within the elastic deformation range of the elastic supplying portion 881c. When the distance H is set within the elastic deformation range of the elastic supplying portion 881c, the contact portion 881b contacts the bonding portion 881a before the elastic supplying portion 881c is plastically deformed, 881 can be prevented.

The side wall 981g 'is formed so as to enclose only one side of the contact portion 981b and the front wall 981g' 'is formed not to extend from the side wall 981g' but to extend from the bonding portion 981a. The rear wall 981g "'extends from the side wall 981g' and is formed to enclose the extending area 981b 'of the contact portion 981b. The functions of the side wall 981g ', the front wall 981g' 'and the rear wall 981g' '' are the same as those described above with reference to FIG. 11a.
