First, 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 infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect 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, have.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, etc. of a touch object to be touched on the touch screen on the touch sensor. 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.

Thus, when 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. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object, which touches the touch screen (or a touch key provided on the touch screen).

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

That is, in the present invention, a middle frame made of stainless steel, which is conventionally required for structural rigidity, is omitted. If the intermediate frame is omitted, the stiffness is weakened. Therefore, one object of the present invention is to compensate for the weakened rigidity. The printed circuit board 225 is an example of a controller 180 for operating various functions of the mobile terminal 200. The printed circuit board 225 includes a plurality of the printed circuit boards 225, ), But it is formed as a single structure in one embodiment of the present invention.

The printed circuit board 281 is electrically connected to an antenna (not shown) and processes a radio signal corresponding to radio electromagnetic waves transmitted and received by the antenna. The antenna is connected to the structure and the printed circuit board 225 And mainly transmits and receives radio signals through the second cover 230. In addition, the printed circuit board 225 may be electrically connected to the second camera 121b. The second cover 230 is formed with a receiving groove 236 for receiving the battery 290 and a battery cover 291 covering the receiving groove 236 is mounted on the second cover 230.

In this embodiment, a thin film transistor-liquid crystal display (TFT LCD) is disclosed as an example of the display module 220, but the present invention is not limited thereto.

For example, the display module 220 may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), a flexible display, a 3D display .

4, both end portions 222a are bent so as to cover the side surfaces of the LCD module 221, so that the LCD module 222 can be prevented from moving in a state where the LCD module 221 is seated have. As such, the first cover 210 may be a front surface cover, and the second cover 230 may be a rear cover.

According to an embodiment of the present invention, the printed circuit board 225 is coupled to the second cover 230. For this purpose, a first boss (not shown) is formed on one surface of the printed circuit board 225, And a second through hole 237 is formed at a position corresponding to the first boss 227 of the second cover 230. The second through hole 237 is formed by a coupling member such as a screw, The first cover 225 may be coupled to the second cover 230.

Also, the printed circuit board 225 may not be directly coupled to the first cover 210 but may be coupled only to the second cover 230. However, in an embodiment of the present invention, The second cover 230, the printed circuit board 225, the LCD module 222, and the first cover 210 may be sequentially coupled to the first cover 210. Referring to FIG. 7, a first through hole 234 is formed in four corners of the second cover 230, and a second through hole 234 is formed in four corners of the second cover 230. In this embodiment, A third through hole 253 is formed in the printed circuit board 225 and a first boss 213 is formed in the first cover 210. The first boss 213 is formed in the first cover 210. [ Since the LCD module 224 including the LCD module 222 is disposed between the first cover 210 and the printed circuit board 225, the first through holes 234, The printed circuit board 225, the LCD module 224, and the first boss 213 by sequentially connecting the first cover 230, the through-hole 253, the first through-hole 223, The rigidity of the LCD module 224 and the printed circuit board 225 can be reinforced by integrally joining the cover 210 to suppress deformation.

The printed circuit board 225 is not necessarily directly fastened to the first cover 210 because the printed circuit board 225 is already coupled to the second cover 230. However, The structural rigidity of the printed circuit board 225 can be further improved by directly fastening the board 225 to the first cover 210. [

The first cover 210 includes a window 211 and a housing 212 on which the window 211 is seated. An operation unit 123a is formed on the window 211, . The housing 212 is formed in a plane perpendicular to the window 211 to form a space in which the LCD module 224 is housed.

The LCD 221 of the LCD module 224 may be a touch-in-cell LCD, and the LCD 211 and the window 211 may be optically clear adhesive (OCA) clear resin, or the like.

However, if OCA or OCR is not used as described above, the material cost can be reduced and the process can be simplified. More specifically, an air gap may be formed between the window 211 and the LCD module 224, and a pad may be provided at the end of the window 221 to compensate for torsional rigidity. However, signal-to-noise ratio (SNR) performance may be degraded if OCA or OCR is not used.

[ Only the first cover 210 and the second cover 230 are exposed to the outside by such a coupling method.

In an embodiment of the present invention, the components 226 are mounted on the surface of the printed circuit board 225 while being divided into a plurality of regions. As described above, in the embodiment of the present invention, the printed circuit board 225 is blocked and standardized (shared) so that other mobile terminals 200 can use the same. However, when the size of the mobile terminal 200 is large, the size of the printed circuit board 225 must be large. At this time, the parts mounted on the printed circuit board 225 (226) and position do not change, and only the space in which the components (226) are not mounted is enlarged.

For example, in a region where the component 226 to be mounted on the printed circuit board 225 is mounted, the fixed region A, which always has a constant size regardless of the size change of the printed circuit board 225, There is a fluctuation region B that increases together with the size of the light source 225. 3, the fixed area A is indicated by a dotted line.

In order to reinforce rigidity, a portion 254a of the shield can 254, It may be inserted and fixed to the circuit board 225. The shield can 254 shields electromagnetic interference (EMI) of various electronic components 226 mounted on the printed circuit board 225.

The second cover 230 covers the printed circuit board 225. The second cover 230 covers a space 228 between the shielding can 254 (232).

Referring to FIG. 3, the rib 232 includes a first rib 2321 formed in a first direction and a second rib 2322 formed in a second direction intersecting the first direction. The first rib 2321 and the second rib 2322 can reinforce the rigidity in the first direction and the second direction, respectively. In this case, the first direction and the second direction may be the longitudinal direction and the width direction of the mobile terminal 200, but the present invention is not limited thereto. For example, the first direction and the second direction may be inclined obliquely with respect to the longitudinal direction or the width direction of the mobile terminal 200 Or may be in a losing direction.

Referring to FIG. 5, a plurality of components are mounted on the printed circuit board 225 in block form. For example, a central processing unit (AP), a power management integrated circuit (PMIC) And an MCP may be blocked in the first area 2251 and Bluetooth (Bluetooth), Wireless Fidelity (WIFI) and Near Field Communication (NFC) may be blocked in the second area 2252, The components may be blocked in the third region 2253 below the regions 2251 and 2252. [

However, the above example is merely an example and is not necessarily limited thereto.

The rib 232 is composed of an upper surface portion 232a and a side surface portion 232b, The side part 232b may be formed to be in contact with the side surface of the adjacent shield can 254. That is, in order to reinforce the rigidity, the width of the ribs 232 may be widened so as to be constrained in the space 228 between the shielding cans 254. The height of the rib 232 may be greater than the height of the shield can 254 because the ribs 232 have a predetermined thickness and the battery 290 is placed on the upper surface 232a of the rib 232. [ It should be formed at a height equal to or higher than the height. If the height of the rib 232 is excessively increased, the insertion space of the battery 290 may be narrowed. Therefore, it is preferable that the height of the rib 232 is the same as the height of the shield can 254. That is, the plane forming the receiving groove 236 described later should not be higher than the shield can 254.

A reinforcing member 240 is provided between the printed circuit board 225 and the second cover 230. The reinforcing member 240 is made of stainless steel so that the intermediate frame is omitted. So that the rigidity of the mobile terminal 200 is reinforced.

The reinforcing member 240 is received in the empty space between the receiving groove 236 and the outer surface of the second cover 230 to prevent the mobile terminal 200 from being thickened by the reinforcing member 240 Respectively. That is, the reinforcing member 240 is formed with a hollow portion 245, and the reinforcing member 240 is formed by the hollow portion 245 so as to surround the receiving groove 236. To this end, The member 240 has a substantially rectangular frame or H beam shape.

In this manner, the size of the printed circuit board 225 is increased by making the size of the printed circuit board 225 correspond to the size of the LCD frame 222. [ As the size increases, even if the components 226 are mounted on only one side, the space is sufficient. When the components 226 are mounted on the one side only, a sufficient space is provided and the LEDs can be coupled to the LCD module 222 by making the size thereof correspond to the LCD module 222, thereby further reinforcing the structural rigidity. For example, in an embodiment of the present invention, the LCD module 222 and the printed circuit board 225 may be bonded together by a double-sided tape 229, The display module 220 having the sum of the thicknesses of the LCD module 222 and the printed circuit board 225 may be formed integrally with each other to enhance the rigidity of the LCD module.
