According to another embodiment of the present invention, the step of forming the penetration preventing part attaches an adhesive tape to a side surface of the display, or engages a frame surrounding the side surface of the display.

According to another embodiment of the present invention, the bonding step bonds the window and the display with an optical transparent adhesive or an optical transparent adhesive resin.

According to another embodiment of the present invention, the step of forming the bonding layer includes injecting an adhesive in a state in which the window is disposed to face the bottom so as to move the adhesive in the window direction from the back surface of the receiving portion.

The step of forming the bonding layer may irradiate the adhesive with ultraviolet rays through the slit to prevent discoloration during curing of the adhesive.

According to another embodiment of the present invention, in the step of forming the bonding layer, the adhesive may be injected by a dispenser moving along two axes.

According to the present invention as described above, since the display and the case are coupled to each other at the side, the display and the case can be combined without the adhesive surface assigned to the back surface of the window for adhesion in the thickness direction of the terminal, And extend the window's video output area.

In addition, since the display and the case can be coupled using the two-axis dispenser, the mobile terminal can be manufactured without using a dispenser moving along three or more axes or a dispenser capable of rotating.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, when the mobile terminal 100 is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. When the mobile terminal 100 is in the video communication mode or the photographing mode, the photographed and / or received video or UI and GUI are displayed.

The display unit 151 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, a 3D display, and an e-ink display.

Some of these displays may be transparent or light transmissive so that they can be seen through. This can be referred to as a transparent display, and a typical example of the transparent display is TOLED (Transparent OLED) and the like. The rear structure of the display unit 151 may also be of a light transmission type. With this structure, the user can see an object located behind the terminal body through the area occupied by the display portion 151 of the terminal body.

There may be two or more display units 151 according to the embodiment of the mobile terminal 100. For example, in the mobile terminal 100, a plurality of display portions 151 may be spaced apart from one another or may be arranged integrally with one another, or may be disposed on different surfaces.

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). The stereoscopic method, which is widely used in home television receivers, includes a Wheatstone stereoscopic method.

Examples of the autostereoscopic method include a parallax barrier method, a lenticular method, an integral imaging method, and a switchable lens method. The projection method includes a reflection type holographic method and a transmission type holographic method.

Generally, 3D stereoscopic images consist of left image (left eye image) and right image (right eye image). A top-down method of arranging a left image and a right image in one frame according to a method in which a left image and a right image are combined into a three-dimensional stereoscopic image, A checker board system in which pieces of a left image and a right image are arranged in a tile form, a left-to-right (right-side) Or an interlaced method in which rows are alternately arranged, and a time sequential (frame-by-frame) method in which right and left images are alternately displayed in time.

In addition, a three-dimensional thumbnail image can be generated from a left image thumbnail and a right image thumbnail, respectively, from the left image and the right image of the original image frame, and a single three-dimensional thumbnail image can be generated by combining the thumbnail image and the right image thumbnail. 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 can display stereoscopic spatial feeling by displaying the left and right distance difference on the screen by the depth corresponding to the parallax between the left image and the right image.

The left and right images required to implement 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 100 or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or a nearby object without mechanical contact using the force of an electromagnetic field or infrared rays. The proximity sensor has a longer life span than the contact sensor and its utilization is also high.

Examples of the proximity sensor 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. And to detect the proximity of the pointer by the change of the electric field along the proximity of the pointer when the touch screen is electrostatic. 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 detects 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, 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, a supersonic bar sensing unit, 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 mobile terminal 100 recognizes which portion of the stereoscopic image has been touched by 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 stereoscopic touch sensing unit 142 senses a pressure to apply a touch, and when the pressing force is strong, the stereoscopic touch sensing unit 142 recognizes the touch with respect to an object located farther 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 sound output module 153 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 154 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events generated in the mobile terminal 100 include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 154 may output a signal for informing occurrence of an event in a form other than a video signal or an audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the audio 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 is vibration. The intensity and the pattern of the vibration generated by the hit module 155 can be controlled by the setting of the user's selection or control unit 180. [ For example, the haptic module 155 may synthesize and output different haptic modules or sequentially output the haptic modules.

The haptic module 155 can be implemented not only to transmit the tactile effect through the direct contact but also to allow the user to feel the tactile effect through the muscular sense of the finger or arm. At least two haptic modules 155 may be provided according to the configuration of the mobile terminal 100.

The memory 160 may store a program for the operation of the controller 180 and temporarily store input / output data (e.g., a phone book, a message, a still image, a moving picture, etc.). The memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

Hereinafter, a structure of a mobile terminal shown in the present invention for minimizing the size of a bezel of a terminal will be described with reference to partial cross-sectional views of FIGS.

4 is a partial cross-sectional view of mobile terminal 200 taken along line A-A of FIG.

The case 201 forms at least a part of the outer surface of the terminal main body. The case 201 may be a front case or a rear case, and the front case and the rear case respectively form at least a part of an outer surface of a front surface and a rear surface of the terminal main body.

The case 201 has a receptacle for receiving the display 210. The display 210 may be formed to occupy most of one side of the main body of the terminal, so that the receiving part may be formed with one side opened and a rim and a bottom.

The display 210 is formed by stacking a plurality of layers, and the layers are stacked to form one module. The display 210 may include a display panel 211, a backlight unit 212 and a reflection plate 213 as shown in the figure, and a backlight unit mold 212 'may be formed at an edge of the backlight unit 212 . The backlight unit mold 212 'is formed so as to surround the edge of the backlight unit 212 to prevent separation and separation of the layers forming the backlight unit 212, And the reflector 213, respectively. Accordingly, the display 210 may be formed of one module.

The display 210 formed of one module is combined with the window 220 disposed to cover the display 210 and is mounted to the receiving portion of the case 201 while being coupled with the window 220. The display 210 and the window 220 may be glued by an optical clear adhesive (OCA) or an optical clear resin (OCR) The window 220 is bonded to the display 210 and forms one surface of the terminal body when the display 210 is attached to the receptacle.

The bonding layer 240 is disposed between the side of the display 210 and the side of the receiving part inserted into the receiving part to couple the display 210 and the case 201 to each other on the side. The adhesive forming the bonding layer 240 adheres the side surface of the display 210 to the portion of the receiving portion facing the display 210 so that a separate step for adhering to the back surface of the window 220 Is not formed.

The display 210 may be directly bonded to the case 201 but it is possible to preclude penetration of the adhesive between the layers forming the display 210 during the bonding process depending on the viscosity of the adhesive forming the bonding layer 240 It is preferable that the penetration preventing part 230 is formed between the display 210 and the bonding layer 240. [

The impermeable portion 230 surrounds the side of the display 210 to prevent the adhesive from penetrating between the layers forming the display 210. The infiltration preventing part 230 may be adhered to the upper surface of the layers and the lower surface of the backlight unit mold 212 'so that the layers forming the display 210 may be formed as a single module.

Since the width of the double-sided tape 214 between the display panel 211 and the backlight unit mold 212 'and between the backlight unit mold 212' and the reflection plate 213 is narrowed to about 0.4 mm, 211 and the lower surface of the backlight unit mold 212 'must be adhered to maintain the display 210 as one module. The penetration preventing portion 230 can prevent the adhesive of the bonding layer 240 from penetrating between the layers of the display 210 as well as prevent the layers from being peeled off by external shocks, have.

When the adhesive tape is adhered to both sides of the reflective plate 213 formed on the outermost layer among the layers forming the display 210, local deformation may occur and cause a failure in normal image information output. Therefore, it is preferable that the adhesive tape forming the penetration preventing part 230 is adhered to the backlight unit mold 212 'and not to the reflection plate 213.

When the penetration preventing portion 230 is disposed between the display 210 and the case 201, the bonding layer 240 is formed between the side of the receiving portion and the penetration preventing portion 230. Accordingly, the adhesive forming the bonding layer 240 bonds the penetration preventing portion 230 and the case 201 together.

There is a limitation in reducing the bezel on the side where the window 220 is disposed in the terminal when a separate stepped portion is formed in the accommodating portion. Since the back surface of the window 220 of the case 201 is not adhered and the display 210 is laterally adhered to the case 201, the bezel can be reduced to a size of 1 mm as compared with the case where the step is formed.

5 is a partial cross-sectional view of a mobile terminal 300 in accordance with another embodiment of the present invention.

The penetration preventing portion 330 may be a frame supporting the display 310. The frame is formed of a hard rigid material, unlike the flexible adhesive tape, to cover at least a part of the back surface, the side surface, and the front surface of the display 310.

The frame wraps at least a portion of the front of the display 310 to hold the display 310 in one module. The reflective plate 313 is bonded to the backlight unit mold 312 'by a double-faced tape 314 on one side thereof. When the tape is adhered to both sides of the reflection plate 313, the reflection plate 313 may be deformed. Therefore, a double-sided tape is not disposed between the reflection plate 313 and the frame. Instead, a frame is formed to enclose at least a portion of the front surface of the display 310 to prevent the display 310 from being detached from the frame, and the frame prevents peeling of the layers so that the display 310 holds one module.

At least one side of the frame is open for engagement between the display 310 and the window 320 and the display 310 is moved to the frame 310 when the size of the display 310 is larger than the open side of the frame, Lt; / RTI > Thus, when at least one side of the side of the frame is opened and the display 310 is inserted at the side of the frame, the display 310 can be mounted inside the frame.

The bonding layer 340 is disposed between the side surface of the receiving portion and the frame to laterally bond the frame and the case 301 to each other. As the bonding layer 340 joins the frame 301 and the case 301 on the side of the display 310, the case 301 does not have a step for adhering to the backside of the window 320, .

6 is a partial cross-sectional view of a mobile terminal 400 in accordance with another embodiment of the present invention.

The infiltration preventing portion 430 may include an adhesive tape 431 that wraps around the side of the display 410 and a frame 432 that is formed to surround the adhesive tape 431 and supports the display 410.

The adhesive tape 431 is bonded from the front of the display 410 to the back side of the backlight unit mold 432 'along the side of the display 410 so that the layers forming the display 410 form one module.

The frame 432 is formed to wrap the adhesive tape 431 and the back surface of the display 410. Even if the frame 432 is not adhered to the front surface of the display 410, the peeling phenomenon does not occur in the display 410 because the adhesive tape 431 is already adhered to the front surface of the display 410. [

The frame 432 and the adhesive tape 431 are adhered by the double-sided tape 416. Since the adhesive tape 431 is a single-sided tape, the surface to be bonded to the backlight unit mold 432 'is sticky, but the opposite surface is not sticky. Thus, another double-sided tape 416 is disposed between the non-adhesive surface and the frame 432 to bond the frame 432 and the adhesive tape 431 together. The double-faced tape 416 is also adherent to both sides of the backlight unit mold and the frame 432 only and is adhered to the reflective plate 413 in a manner to prevent local deformation of the reflective plate 413. [ It is preferable not to be formed.

The bonding layer 440 is disposed between the frame 432 and the receiving portion and the adhesive forming the bonding layer 440 side-bonds the case 401 and the display 410. Since the display 410 and the case 401 are adhered to each other at the side, the case 401 is not provided with a step for adhering to the rear surface of the window 420. [ Accordingly, the bezel of the terminal can be minimized.

7 is a partial cross-sectional view of a mobile terminal 500 in accordance with another embodiment of the present invention.

7 differs from the mobile terminal 400 shown in FIG. 6 in that the infiltration prevention portion 530 of the mobile terminal 500 includes a frame 532 and a frame 532 formed to surround the side and the back of the display 510, And an adhesive tape 531 formed so as to surround the side surface of the base 532.

6, the positions of the frame 532 and the adhesive tape 531 are exchanged with each other. Likewise, the double-sided tape 514 is adhered to only one side of the reflection plate 513, The tape does not stick. The adhesive tape 531 is formed to cover at least a part of the front surface of the display 510 and the side surface and the back surface of the frame 532 so that the layers forming the display 510 can be made of one module.

The case 501 is provided with a slit 501a formed along the rim of the bottom surface of the receiving portion so as to be able to form the bonding layer 540 by injecting adhesive from the back surface. The adhesive injected through the slit 501a is injected into the side surface of the receiving portion with the adhesive tape 531 to bond the penetration preventing portion 530 and the case 501 together.

The slits 501a are formed not only in the case 501 of the mobile terminal 500 shown in Fig. 7 but also in the cases 201, 301 and 402 of the mobile terminals 200, 300 and 400 shown in Figs. 401).

The slit 501a may be formed along at least a part of the longitudinal direction and the width direction of the terminal so that the adhesive can be injected using a dispenser moving along two axes. In this case, one axis in which the dispenser moves is the longitudinal direction of the terminal and the other axis is the width direction.

The case 501 is provided with a leakage preventing portion 501b formed along the rim of the accommodating portion side so as to prevent the adhesive forming the bonding layer 540 from leaking into the gap between the window 520 and the side surface of the accommodating portion . The leakage preventing portion 501b is formed protruding from the side surface of the receiving portion. The leakage preventing portion 501b is not intended to be adhered to the window 520 but to prevent a gap between the case 501 and the window 520. [ The size of the bezel can still be minimized even when the leakage preventing portion 501b is formed in the case 501 as compared with the case where the step is formed to adhere to the back surface of the window 520. [

FIG. 8 is a flowchart illustrating a method of manufacturing a mobile terminal according to an embodiment of the present invention, and FIG. 9 is a partial cross-sectional view illustrating a manufacturing process of the mobile terminal according to the flowchart shown in FIG.

The step of forming the layers forming the display into one module (SlOO) is for preventing peeling of the layers. Each layer can be bonded to other layers placed on both sides. A backlight unit mold is disposed at the rim of the backlight unit, and a display panel and a reflection plate are disposed on both sides of the backlight unit, and bonded to the backlight unit mold by the double-sided tape. Accordingly, the layers forming the display may be formed of one module.

In the step S200 of forming the penetration preventing portion on the side of the display, an adhesive tape is attached to the side of the display formed of one module or bonded to the frame. The adhesive tape and the frame may form one penetration preventing portion.

When the anti-penetration portion is formed of an adhesive tape, an adhesive tape is stuck on at least a part and a side surface of the front and back surfaces of the display. When the anti-penetration part is formed as a frame, the display is inserted through one side opened on the side surface of the frame.

When the anti-penetration portion is formed of an adhesive tape and a frame, it is possible to attach an adhesive tape to the side surface of the display and attach the frame to the outside of the adhesive tape. Alternatively, have.

In the step S300 of joining the window to the display, the window is bonded to the front surface of the display having the anti-penetration portion. The window may be adhered to the display by optical transparent adhesive (OCA) or optical transparent adhesive resin (OCR).

In the step S400 of inserting the display into the receiving part of the terminal case, the window is mounted on one side of the terminal and the display is arranged on the back side of the window.

In step S500 of forming the bonding layer, an adhesive is injected between the side surface of the accommodating portion and the penetration preventing portion through the slit formed along the rim of the bottom portion of the accommodating portion.

Applying the adhesive first to the sides of the receptacle and bonding the display can cause the adhesive to leak into the gap between the window and the case. However, in the present invention, since the display is first bonded to the case and then the adhesive is injected through the back surface of the case, if the viscosity of the adhesive is adjusted only, the injected adhesive is prevented from penetrating into the gap between the window and the case, It can be induced to evenly spread between the side surfaces of the portions.

The bonding layer is formed by curing the injected curing agent. In the step of forming the bonding layer, ultraviolet rays may be applied to the adhesive to cure the adhesive, and ultraviolet rays may be irradiated through the slit, thereby preventing discoloration from occurring depending on the color of the window.

10 is a plan view of a case for illustrating a step of forming a bonding layer of a mobile terminal.

An adhesive is injected to form a bonding layer on the terminal, but the present invention can inject the adhesive using a dispenser moving along two axes. In the case 601, a plurality of slits 601a are formed along the rim of the bottom of the receiving part, and the slits 601a may be formed along the longitudinal direction of the terminal, as shown in the figure. The slits 601a may be formed along the width direction of the terminal, or may be formed in a rectangular shape along the longitudinal direction and the width direction of the terminal.

The dispenser is moved along the two axes while moving in the longitudinal direction of the terminal, the adhesive is injected into each of the slits 601a formed in a line, and another slit 601a formed in a line at a position spaced apart from the slits 601a, The adhesive can be injected into the holes 601a.

Particularly, when the dispenser moves along the two axes and drops the adhesive to the slit 601a through the nozzle, the dropped adhesive flows between the case and the infiltration preventing portion through the slit 601a to form a side coupling. Therefore, the economizer of the mobile terminal can be improved because the dispenser does not have to rotate or move along three or more axes.

The case 601 may have a plurality of slits formed on the edge of the bottom surface for injecting an adhesive and a bridge 601a may be provided between the slit 601a and the slit 601a to prevent the strength of the case 601 from being lowered. (601a ').

In addition, in order to realize a bezel of 1 mm, there is no pattern width in the window or a small in-cell touch or active area even if the touch pattern width is not a critical path of the bezel. It is preferable to apply a touch method in which a touch pattern is realized.
