When the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by a change in electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, the act of allowing an object to be recognized as being located on the touch screen without being touched on the touch screen is called a “proximity touch”, and the touch The act of actually contacting an object on the screen is called "contact touch". The location where an object is touched close on the touch screen means a location where the object is perpendicular to the touch screen when the object is touched close.

The ultrasonic sensor may recognize location information of a sensing target using ultrasonic waves. Meanwhile, the control unit 180 may calculate the position of the wave generating source through information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave generator can be calculated by using a property in which light is much faster than ultrasound, that is, a time when light reaches the optical sensor is much faster than a time when the ultrasound reaches the ultrasonic sensor. More specifically, the position of the wave generating source may be calculated by using a time difference from the time at which ultrasonic waves reach the light as a reference signal.

The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object close to the touch screen. More specifically, the photo sensor mounts photo diodes and TRs (transistors) in rows / columns to scan the contents loaded on the photo sensor using electrical signals that change according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the sensing object according to the change amount of light, and through this, location information of the sensing object may be obtained.

The window 151 "is bent along one direction. For example, the window 151 "may be formed to be curved along the longitudinal direction L of the terminal body, and may have a predetermined radius of curvature.

As shown, the flat liquid crystal panel 151a is attached to the rear surface of the window 151 ". By the above attachment, the liquid crystal panel 151a is deformed into a curved shape corresponding to the shape of the window 151", At this time, the liquid crystal panel 151a may have a predetermined radius of curvature.

The curved liquid crystal panel 151a can be easily implemented.

Meanwhile, the backlight units 151b are attached to the frames 101 and 104. The backlight unit 151b is formed in a curved shape to correspond to the curved liquid crystal panel 151a. Here, the formation of the curved shape includes not only that the backlight unit 151b manufactured in a flat shape is transformed into a curved shape through post-processing or an assembly process, but also that the backlight unit 151b is manufactured in a curved shape.

The bottom surfaces of the frames 101 and 104 to which the backlight unit 151b is attached may be formed in a curved shape along one direction so as to correspond to the curved direction of the window 151 ". Furthermore, the frames 101 and 104 are The frame 101 or 104 may be formed of various materials such as a metal material (for example, stainless steel, magnesium, aluminum, etc.) or synthetic resin material.

An adhesive member 132 is provided between the backlight units 151b and the frames 101 and 104 to couple the backlight units 151b to the frames 101 and 104. As the adhesive member 132, an adhesive or an adhesive tape such as Optical Clear Adhesive (OCA) or Optical Clear Resin (OCR) may be used.

When the backlight unit 151b is coupled to the frames 101 and 104 by the adhesive member 132, it is bent by external force, and the frames 101 and 104 exert an external force that bends the backlight unit 151b, that is, bending force. To create.

FIG. 6 is an exploded perspective view of the mobile terminal 100 shown in FIG. 2, and FIG. 7 is a cross-sectional view taken along the line A-A shown in FIG. 2. For reference, in the exploded perspective view of FIG. 6, only some configurations related to the present invention are illustrated.

6 and 7, the frames 101 and 104 include a base frame 101 and a middle frame 104. Frames 101 and 104 may be made of a combination of different materials. For example, the base frame 101 may be formed of a synthetic resin material, and the middle frame 104 may be formed of a metal material.

The base frame 101 is coupled to the window 151 ". At least a portion of the base frame 101 is exposed to the outside to form a side appearance of the terminal body.

The base frame 101 may include a back support portion 101a and a side cover portion 101b.

The back support portion 101a supports the back surface of the window 151 ". The back support portion 101a may form a loop corresponding to the edge region to support the back edge region of the window 151".

The side cover portion 101b is disposed to cover the side surface of the window 151 ". The side cover portion 101b may protrude to form the same plane as the upper portion of the window 151". According to the above structure, when the mobile terminal 100 is viewed from the front, a step between the windows 151 "and the frames 101 and 104 is not revealed, so that a cleaner appearance of the mobile terminal 100 can be realized.

A bonding portion 133 is provided between the base frame 101 and the window 151 ", so that the window 151" is coupled to the frames 101 and 104. In this embodiment, it is shown that the bonding portion 133 is provided between the window 151 "and the back support portion 101a. The bonding portion 133 is a bonding layer or a back support portion applied on the back support portion 101a. It may be an adhesive tape attached on the 101a.

When the bonding portion 133 is implemented as a bonding layer applied on the back support portion 101a, a portion of the bonding layer is introduced between the back support portion 101a and the side cover portion 101b to restrict flow to the side The groove 101c may be formed. In this figure, it is illustrated that the inflow groove 101c is formed in the back support portion 101a.

The middle frame 104 is coupled to the base frame 101 and provides a space in which the backlight unit 151b is seated. For example, the middle frame 104 is formed of a metal material, and may be integrally coupled to the base frame 101 formed of a synthetic resin material through insert injection.

A heat radiation hole 104a for heat dissipation may be formed in the middle frame 104. The heat radiation holes 104a are formed in the middle frame 104, and heat generated from the backlight unit 151b may be discharged to the space on the rear surface of the middle frame 104. 8 and 9 illustrate that the heat dissipation holes 104a are spaced apart at predetermined intervals along the side edges of the middle frame 104.

Meanwhile, although the middle frame 104 is configured separately from the base frame 101 in the present exemplary embodiment, the structure of the frames 101 and 104 is not limited thereto. The base frame 101 and the middle frame 104 may be formed of a single member. For example, the base frame 101 and the middle frame 104 may form frames 101 and 104 integrally formed by injection molding.

The backlight unit 151b is coupled to the middle frame 104. The middle frame 104 to which the backlight unit 151b is attached is formed in a curved shape along one direction. In FIG. 6, when the backlight unit 151b manufactured in a flat shape is mounted on the middle frame 104, it is illustrated that it is transformed into a curved shape by receiving a bending force by the curved shape of the middle frame 104.

However, the backlight unit 151b does not necessarily have a curved shape by this coupling structure. The backlight unit 151b may be manufactured in a curved shape along the one direction, or may be deformed in a curved shape along the one direction before being attached to the middle frame 104 and mounted on the middle frame 104.

As such, according to the structure in which the backlight unit 151b is attached to the bottom surface of the middle frame 104, the gap between the existing middle frame 104 and the backlight unit 151b is removed, and the slimmer mobile terminal 100 Can be implemented.

On the other hand, the inside of the frame (101, 104) is provided with a reflector formed to reflect light leaking from the backlight unit (151b). In FIG. 7, a reflective member 134 coupled to the frames 101 and 104 as a reflector and disposed to surround a side surface of the backlight unit 151b is illustrated. The reflective member 134 may be formed of a white-based synthetic resin material to reflect light, or may be formed to have high brightness through post-processing such as coating and deposition.

As illustrated, the reflective member 134 may be disposed at a corner portion between the base frame 101 and the middle frame 104. Further, the reflective member 134 may be integrally coupled to the frames 101 and 104 through double injection or triple injection.

The middle frame 104 may be formed of a high-brightness material to reflect light leaking from the backlight unit 151b, or may have a high-brightness through post-processing such as coating and deposition.

As described above, according to the structure in which the reflecting portion is provided inside the frames 101 and 104, the white mold previously provided in the backlight unit 151b is removed, so that the side surfaces of the frames 101 and 104 and the backlight unit 151b are removed. The gap can be reduced. As a result, the bezel can be reduced and a mobile terminal 100 that can be configured with a large screen compared to the same area can be provided.

On the other hand, the window 151 "to which the liquid crystal panel 151a is attached is coupled to the frames 101 and 104 to which the backlight unit 151b is attached. A state in which the window 151" is coupled to the frames 101 and 104 In, the backlight unit 151b is disposed on the rear surface of the liquid crystal panel 151a. At this time, a predetermined gap may be formed between the liquid crystal panel 151a and the backlight unit 151b.

A light blocking member 151c for preventing light leakage from the backlight unit 151b is provided between the liquid crystal panel 151a and the backlight unit 151b. The light blocking member 151c is formed in a loop shape extending along the upper edge of the backlight unit 151b to separate the inner space between the liquid crystal panel 151a and the backlight unit 151b from the outer space.

In this drawing, it is illustrated that the light blocking member 151c is disposed to cover the upper edge of the backlight unit 151b and the reflective member 134. It is preferable that the reflective member 134 protrudes to form the same plane as the upper portion of the backlight unit 151 b so that the light blocking member 151 c can be stably mounted on the backlight unit 151 b and the reflective member 134.

The light blocking member 151c may be in close contact with the liquid crystal panel 151a and the backlight unit 151b, respectively, to prevent foreign matter from penetrating between the liquid crystal panel 151a and the backlight unit 151b. The light blocking member 151c is preferably formed of a predetermined elastically deformable material (eg, silicone, rubber, etc.). In addition, during the close contact, in order to prevent the occurrence of unevenness of the liquid crystal panel 151a due to pressing, cracking of the liquid crystal panel 151a or the backlight unit 151b, the light blocking member 151c has a liquid crystal panel 151a and a backlight. It is thicker than the gap between the units 151b, and the thickness of the light blocking member 151c should be considered in consideration of the elastic deformability.

As described above, the light leakage generated from the backlight unit 151b is prevented by the light blocking members 151c that are respectively in close contact with the liquid crystal panel 151a and the backlight unit 151b, and the liquid crystal panel 151a and the backlight unit are prevented. Ingress of foreign substances between the (151b) can also be prevented.

8 is a plan view of the frames 101 and 104 shown in FIG. 6.

As described above, only the flat liquid crystal panel 151a is attached to the curved window 151 ". According to the above structure, the flat liquid crystal panel 151a and the backlight unit 151b are attached to the curved window 151". Compared to the structure, the force received by the window 151 "(ie, the force that deforms the window 151" into a flat shape) is reduced.

Therefore, the window 151 "can maintain a curved state without significant deformation, and can maintain a stable state coupled to the curved frames 101 and 104. According to the above structure, the configuration of the bonding portion 133 In addition, it may vary. Hereinafter, an example of the bonding unit 133 will be described.

Referring to FIG. 8, the bonding portion 133 may be disposed on the back support portion 101a of the base frame 101. Both sides of the back support portion 101a corresponding to the width direction W of the terminal body are formed with an elongated area compared to both ends of the back support portion 101a corresponding to the longitudinal direction L of the terminal body.

Meanwhile, in order to apply the bonding layer to the back support portion 101a, a minimum area for controlling the flow of the liquid is required. However, the area on both sides of the back support portion 101a corresponds to a fairly small area for applying the bonding layer. This is especially true considering the current trend of the mobile terminal 100 in which the side bezel is being reduced.

Accordingly, the bonding portion 133 may be formed of a combination of adhesive tapes 133a provided on both sides of the back support portion 101a and bonding layers 133b provided on both ends of the back support portion 101a, respectively. Since the bonding strength of the bonding layer 133b is greater than that of the adhesive tape 133a, the bonding between the window 151 "and the base frame 101 is mainly made by the bonding layer 133b, and the adhesive tape 133a is It can be made to assist the coupling.

As shown, the adhesive tape 133a may extend from one end of the back support portion 101a toward the other end.

9 is an enlarged view of part B shown in FIG. 6.

In this figure, it is illustrated that a touch sensor is formed or attached to the rear surface of the window 151 ", and a flexible circuit board 182 electrically connected to the touch sensor is disposed at one end of the window 151".

A hole 101d through which the flexible circuit board 182 penetrates is formed in the base frame 101, specifically, the back support portion 101a. The flexible circuit board 182 may pass through the hole 101d and be electrically connected to a circuit board (not shown) disposed on the rear surface of the middle frame 104.

As described above, the back support portion 101a is provided with a bonding portion 133 for coupling the window 151 "to the frames 101 and 104. When the window 151" is seated on the back support portion 101a , The hole 101d is formed at a position corresponding to the flexible circuit board 182 so that the flexible circuit board 182 can directly pass through the hole 101d without bending. According to the above structure, the area of the bonding portion 133 on the back support portion 101a may be increased.

10 is an exploded view showing another example of the mobile terminal 200 according to the present invention.

Referring to FIG. 10, the flat liquid crystal panel 251a is attached to the rear surface of the window 251 ", and is formed in a curved shape corresponding to the window 251". At this time, the liquid crystal panel 251a is subjected to a bending force due to the curved shape of the window 251 ".

On the other hand, the backlight unit 251b has a somewhat curved shape in accordance with the curved shape of the frames 201 and 204 before being attached to the frames 201 and 204. For example, the backlight unit 251b may be manufactured in a curved shape along one direction, or may be deformed into a curved shape along one direction before attachment to the frames 201 and 204 through equipment (JIG) or manual operation.

The backlight unit 251b may be bent to correspond to the bent frames 201 and 204, or less bent. As such, the curved backlight unit 251b is attached to the curved frames 201 and 204.

With the backlight unit 251b coupled to the frames 201 and 204, the degree of curvature of the backlight unit 251b is substantially the same as in the previous embodiment. However, since the backlight unit 251b has a curved shape before the attachment of the frames 201 and 204, the backlight unit 260b receives the bending force and the bending force received by the backlight unit 251b due to the curved shape of the frame 201 and 204 ( The restoring force of 251b) is reduced compared to the previous embodiment. According to this coupling structure, the area of the adhesive member that couples the backlight unit 251b to the frames 201 and 204 can be reduced.

To implement this, a method of applying the bonding layer 333 to the back support portion 301a and the side cover portion 301b in the manufacturing process may be considered. However, it is not only difficult to apply the bonding layer 333 to the thin side cover part 301b, but also the bonding layer applied to the side cover part 301b when the window 351 "is coupled to the base frame 301 ( A part of 333) may flow out.

To prevent this, an inclined guide portion 301c is formed between the back support portion 301a and the side cover portion 301b, and the bonding layer 333 may be applied only to the back support portion 301a. According to this, when the window 351 "is coupled to the base frame 301, the bonding layer 333 applied to the rear support portion 301a flows into the side cover portion 301b by the inclined guide portion 301c. As a result, the bonding layer 333 is applied to both the back support portion 301a and the side cover portion 301b, so that the adhesion between the window 351 "and the base frame 301 can be enhanced by an increase in the bonding area. have.
