Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner region of the mobile terminal 100 covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the 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 explanation, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch.

The photo sensor may be stacked on a display element, which is configured to scan a movement of a sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

The second decor part 420 supports the window 430 and protrudes from the support part 420a and the support part 420a which are bonded to the first waterproof layer 311, and an end surface of the window 430 is formed. And an exposed portion 420b exposed through the opening hole 430 '. Accordingly, the rear cover 103 includes a first deco part 410 surrounding the window 430 and a second deco part 420 surrounding the flash window 441.

On the other hand, between the second decor 420 and the window 430 (ie, the opening hole 430 ′) flows in between, or between the flash window 441 and the second decor 420 In order to block water flowing through the space, a second waterproof layer 312 is formed under the flash sensor.

One surface of the second waterproof layer 312 is attached to the recess 413 of the first decor 410, and the other surface of the second waterproof layer 312 is attached to the first region 241a of the flash window 441. . Since the flash window 441 and the second waterproof layer 312 are bonded to each other, the inflow of water into the third hole 412c of the first decor 410 is blocked. Since the flash sensor module 442 is disposed below the flash window 441, the flash sensor module 442 and the internal space where the flash sensor module 442 is disposed may be a waterproof area.

A third waterproof layer 324 is attached between the second area A2 of the first decor part 410 and the inner frame 104. One region of the first decor part 410 extends from the support part 414 in a direction opposite to the protruding direction of the exposed part 411 and is supported by the inner frame 104.

A gap between the first and third decor parts 410 and 470 and the rear cover by the third waterproof layer 324 formed between the inner frame 104 and the first decor part 410. Even if water flows in through the gap between the third decoration unit 103 and the third decor unit 470, the water does not flow into the inner space where the camera module and the flash sensor are disposed, and thus flooding can be prevented.
