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.

Figure 3 is a cross-sectional view of portion F of Figure 2a in accordance with an embodiment of the present invention.

Referring to FIG. 3, the display unit includes a window 200 and a display module 201.

The display unit may further include a touch pattern. The touch pattern may be integrated with the display module 201 by adopting an Incell Touch LCD (Incell Touch LCD) method. According to the Insel-Touch LCD method, since the touch pattern is not stacked on one side of the window 200, the protrusion amount of the window 200 can be minimized.

More specifically, the window 200 includes a first area overlapping the touch pattern and a second area corresponding to an outer edge of the first area. When the touch pattern is formed to be laminated on one surface of the window 200, connection lines connecting the touch pattern and the flexible circuit board should be disposed in the second area. In the in-cell touch LCD method, the size of the second area can be reduced.

The display module 201 is seated in a set mechanism. The set mechanism may be a printed circuit board 182. The set mechanism, the display module 201 and the window 200 are stacked in this order. The double-sided tape is disposed between the back of the set mechanism and the display module 201 and the bonding is maintained by the adhesive force of the double-sided tape. The window 200 and the display module 201 may be coupled to each other by transparent adhesive 202 such as OCA (Optically clear adhesive) or OCR (Optically clear resin).

Since the adhesive means such as OCA and OCR are formed of a transparent material, their bonding strength is lower than that of the double-sided tape due to their low density. Thus, in the prior art, the edge of the window 200 and the housing of the display module 201 are joined by the double-sided tape to firmly couple the window 200 and the display module 201 together.

At this time, the double-sided tape needs a space that can be arranged with a width of at least 0.8 mm or more. When the mobile terminal is viewed from the front, the bezel is outside the region 200a where the screen is displayed. If the double-sided tape is used as in the prior art, the bezel is extended as much as the space where the double-

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems and it is an object of the present invention to provide a joining structure capable of strongly bonding a window 200 to a terminal body by changing a lamination bonding method of a window 200 and a case to a side- .

According to the drawings, the side edge of the window 200 is fixed in contact with the side wall of the case. The side wall includes a frame 301 formed with a metal material, and an injection member 302 injection-molded to enclose at least a part of the frame 301.

The side end of the window 200 may be fixed to the case side wall with double-sided tape. Also, according to one embodiment of the present invention, the side end of the window 200 and the side wall of the case may be adhered by the adhesive 203.

Figures 4 and 5 are cross-sectional views of portion F of Figure 2a in accordance with another embodiment of the present invention.

Referring to FIG. 4, a first groove 303a is formed in the side wall of the case so that the adhesive 203 can be easily introduced into the space between the case and the side edge of the window 200. The first groove 303a is formed by being recessed in the thickness direction of the case side wall. The first groove 303a may be formed so as to be closer to the side edge of the window 200 toward the upper end in order to improve the esthetics of the appearance of the terminal. That is, it is difficult to confirm existence of the first groove 303a in the outside.

According to an embodiment of the present invention, the lower end of the first groove 303a further includes a second groove 303b in the case side wall. The second groove 303b provides a space in which the adhesive 203 flowing downward by gravity can be rolled up. That is, it is possible to prevent the devices 203 from malfunctioning due to the fluidity of the adhesive 203 before flowing into the terminal.

The second groove 303b is formed to have a circular cross-section as shown in the drawing, thereby maximizing the space in which the adhesive 203 is held.

Referring to FIG. 5, the side walls of the case further include protrusions 302a protruding upward from one side of the first groove 303a. As shown, the protrusions 302a protrude so as to form a layer on the lower surface of the first groove 303a.

The protrusion 302a prevents the adhesive 203 from being introduced into the terminal along the lower surface of the window 200 after the adhesive 203 is filled in the first groove 303a and the second groove 303b. According to an embodiment of the present invention, the upper surface of the projection 302a is formed to be in contact with the lower surface of the window 200. [

Figure 6 is a cross-sectional view taken along line VI-VI of Figure 2a.

Referring to FIG. 6, the side wall of the case includes a frame 301 formed of a metal material, and a plastic material formed to surround at least a part of the frame 301.

According to an embodiment of the present invention, the plastic material may be an injection member 302 injection molded to enclose the frame 301.

6 (a) and 6 (b) show a frame 301 having a hole structure. The hole structure refers to a structure capable of maximizing the size of the hole 303 passing through the metal frame 301. With this structure, it is possible to minimize the reduction of antenna performance by the metal frame 301.

In order to minimize antenna performance degradation, the frame may have one large hole in the middle, but the size of the hole 303 may be reduced in consideration of securing the rigidity of the case along with antenna performance, and may be formed to be repeated at regular intervals.

The hole 303 may have a circular shape as shown in FIG. 6 (b), or may have a polygonal shape having a plurality of edges. Fig. 6 (a) shows an embodiment in which there are four corners.

6 (c) and 6 (d) show a frame 301 having a bridge structure. The bridge structure refers to a structure including a connection portion across the hole 303, and is a structure that is strong against impacts compared to the hole structure.

As shown, the bridge structure may be a structure including a connection portion connecting the corners in the frame 301 of the hole structure. Referring to Fig. 6 (d), the frame 301 includes a first connection portion 301b connecting a second edge having a greatest distance from the first edge. In addition, the frame 301 may further include a second connection portion 301a connecting the first connection portion 301b and the third edge. The impact applied to the terminal by the first connection part 301b and the second connection part 301a can be dispersed. For example, since a hole is formed in the middle of a frame, if a shock such as dropping the terminal is applied, the frame may be twisted and the case may be broken. However, the frame is prevented from being twisted by the connecting portion that crosses the hole, and the durability of the case can be increased.

7 is an exploded perspective view of the mobile terminal shown in FIG.

As shown, the case includes a left side wall 101a, a right side wall 101c, an upper side wall 101b and a lower side wall 101d. A frame 301 is included in at least one side wall of the side walls.

The antenna for receiving broadcasting signals 116 may be disposed on one side of the rear case, apart from an antenna for communication and the like. The antenna 116 may be installed to be able to be drawn out to the rear case.

In general, when the antennas are disposed close to the space where the electric elements are mounted, such as the display module 201, the radiation efficiency of the antenna tends to be reduced. Therefore, when the terminal case is used as a part of the radiator, satisfactory antenna performance can be realized while maximizing the space efficiency of the terminal.

As shown in the figure, a mobile terminal according to an embodiment of the present invention may include a communication antenna 210 adjacent to one side wall 101d of the terminal. The communication antenna 210 may use a part of the case formed along the side surface of the terminal body as a part of the conductive member.

According to an embodiment of the present invention, a metal frame 301 may not be included in one side wall 101d adjacent to the communication antenna 210. [ That is, the one side wall 101d is made of a plastic material. The side walls 101a, 101b, and 101c except for the one side wall 101d are formed to include the metal frame 301, so that the rigidity of the terminal case is secured. In addition, since the metal frame 301 is not included in one side wall 101d adjacent to the communication antenna, the performance of the communication antenna is prevented from being deteriorated by the metal.

The antenna exhibits excellent radiation performance according to the order of copper (Cu), aluminum (Al), magnesium (Mg), and iron (Fe) The side walls 101d adjacent to the antenna for communication do not include the frame 301 made of metal and the other side walls 101a, 101b and 101c include the frame 301 made of copper, aluminum, magnesium or iron So that the antenna radiation performance can be improved.

8A and 8B are conceptual diagrams for explaining the case manufacturing principle of the insert chassis metal structure of the present invention.

8A, after a metal frame 301 is inserted between the upper mold 401 and the lower mold 402, at least a part of the frame 301 is covered as shown in FIG. 8B The injection member 302 is injection-molded.

That is, an insert sash metal structure, which is not a one-body metal structure in which the entire sidewalls are made of metal, is introduced to minimize the thickness of a sidewall of a case necessary for securing strength, Is minimized.

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