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 existing in the vicinity using the force of an electromagnetic field or infrared rays without mechanical contact. In the proximity sensor 141, the proximity sensor 141 may be disposed in an inner area of the mobile terminal surrounded by the touch screen as described above or near the touch screen.

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 type proximity sensor, a magnetic type proximity sensor, an infrared proximity sensor, and the like. When the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of the object by a change in 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, the action of allowing an object to be recognized as being positioned on the touch screen by being approached without contacting an object on the touch screen is called "proximity touch", and the touch The act of actually touching an object on the screen is referred to as "contact touch". A position at which an object is touched in proximity on the touch screen means a position at which the object is vertically corresponding to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.). have. Meanwhile, as above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141, and further, provides visual information corresponding to the processed data.

Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

In this way, when there is a touch input to the touch sensor, the signal(s) corresponding thereto is transmitted to the touch controller. The touch controller processes the signal(s) and then transmits the corresponding data to the controller 180. As a result, the controller 180 can know whether an area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or perform the same control according to the type of the touch object by touching the touch screen (or a touch key provided in addition to the touch screen).

The ultrasonic sensor may recognize location information of a sensing target using ultrasonic waves. Meanwhile, the controller 180 may calculate the location of the wave generator through information sensed from the optical sensor and the plurality of ultrasonic sensors. The location of the wave generator may be calculated by using a property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time that the ultrasonic wave reaches the ultrasonic sensor. More specifically, the location of the wave generator may be calculated using a time difference between a time when the ultrasonic wave arrives using light as a reference signal.

On the other hand, the camera 121, viewed as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

The photosensor may be stacked on the display device, and the photosensor is configured to scan a motion of a sensing object close to the touch screen. More specifically, the photo sensor scans the contents placed on the photo sensor by mounting a photo diode and a transistor (TR) in a row/column and using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photosensor calculates the coordinates of the sensing object according to the amount of light change, and through this, position information of the sensing object may be obtained.

Can be formed.

The widths w1 and w2 of the convex surface 1112a may vary according to the specific viewing range. Specifically, as the convex surface 1112a has a wider width w1, the reflected light is biased in a direction perpendicular to the front surface 1110 of the cover 1100. Alternatively, as the convex surface 1112a has a narrower width w2, the reflected light is skewed toward the center of the cover 1100 or in a direction in which the first flat surface 1111 is located. For example, the width of the convex surface 1112a may be 1.0mm to 2.0mm.

5(a) and 5(c), when the width at which the convex surface 1112a or the first chamfer surface 1112b is formed is wide, the angle formed between the reflected light and the incident light is relatively small. do. That is, the reflected light is relatively less refracted than when the width of the convex surface 1112a or the first chamfer surface 1112b is narrow.

5(b) and 5(d), when the width at which the convex surface 1112a or the first chamfer surface 1112b is formed is narrow, the angle formed by the reflected light and the incident light is relatively large. do. That is, the reflected light is more refracted than when the width of the convex surface 1112a or the first chamfer surface 1112b is wide, and the amount of reflected light that is totally reflected is also increased. In addition, when having the same width, the convex surface 1112a refracts the reflected light more than the first chamfer surface 1112b. Further, as the convex surface 1112a concentrates the reflected light more in a specific direction than the first chamfer surface 1112b, a change in color density of the reflected light according to an angle is large.

6 is a diagram illustrating a path of reflected light according to an angle of incident light of the window glass 1000 according to an embodiment of the present invention.

6(a) to 6(e) show incident light according to the position of the light source 10 of the window glass 1000 including a convex surface 1112a around the front surface 1110 of the cover 1100 and It is a figure which shows each path of reflected light. Unlike FIG. 5, the incident light enters the front surface 1110 of the cover 1100 at various angles.

Referring to FIGS. 6A to 6E, as described above, the convex surface 1112a refracts the reflected light reflected from the reflective layer 1300 within a specific viewing angle range.

Specifically, as shown in Figs. 6(a) and 6(b), when the incident light is incident at a large angle with the convex surface 1112a, the convex surface 1112a is the cover 1100 Reflected light reflected from the reflective layer 1300 provided on the rear surface 1120 of is completely reflected, thereby preventing the reflected light from being refracted outside the front surface 1110 of the cover 1100. On the other hand, as shown in Figs. 6(c) to 6(e), when the incident light enters at a relatively small angle with the convex surface 1112a, the convex surface 1112a reflects the reflected light. It refracts to the outside of the cover 1100 so that it can be visually recognized. That is, as part of the reflected light is blocked, the convex surface 1112a forms a specific viewing angle range in which the reflected light can be visually recognized. Hereinafter, the viewing angle range of the window glass 1000 of FIG. 6 will be described in detail with reference to FIG. 9(a).

7 is a diagram illustrating a path of reflected light according to an angle of incident light of a window glass 1000 according to another embodiment of the present invention.

7(a) to 7(e) show the position of the light source 10 of the window glass 1000 including a first chamfer surface 1112b around the front surface 1110 of the cover 1100. It is a diagram showing paths of incident light and reflected light, respectively.

7(a) to 7(e), the first chamfered surface 1112b, like the convex surface 1112a of FIG. 6, reflects the reflected light from the reflective layer 1300 in a specific viewing angle range. Refracts inward.

However, referring to FIG. 7(b), unlike the convex surface 1112a of FIG. 6, the first chamfer surface 1112b has a relatively large angle to the front surface 1110 of the window glass 1000. Even when incident is made while forming, total reflection does not occur, so that the reflected light is refracted to the outside of the glass cover 1100. That is, the first chamfer surface 1112b forms a specific viewing angle range larger than that of the convex surface 1112a.

In addition, referring to FIGS. 7(c) to 7(e), the first chamfered surface 1112b refracts the reflected light to be dispersed more than the convex surface 1112a of FIG. Forms a large viewing angle range. Further, the first chamfered surface 1112b is more uniformly distributed than that of the convex surface 1112a, thereby providing a constant color according to the viewing angle. Hereinafter, the viewing angle range of the window glass 1000 of FIG. 7 will be described in detail with reference to FIG. 9B.

8 is a diagram illustrating a path of reflected light according to an angle of incident light of the window glass 1000 according to another embodiment of the present invention.

Here, the end portion 1130 of the cover 1100 has a certain thickness and may be bent in a direction in which the rear surface 1120 of the cover 1100 faces.

Like the convex surface 1113 of FIG. 6, the convex surface 1113 and the concave surface 1123 refract the reflected light reflected from the reflective layer 1300 within a specific viewing angle range.

8(a) to 8(b), the window glass 1000 has total reflection of the reflected light inside the cover 1100, unlike FIGS. 6(a) to 6(b). Since it does not occur, the reflected light is refracted to the outside of the cover 1100.

Referring to FIG. 8 (c), unlike FIGS. 5 and 6 (c), the window glass 1000 transmits incident light incident in the vertical direction of the window glass 1000 to the end of the cover 1100. The reflected light is refracted in the direction (1130). Here, the direction of the end portion 1130 may be a side direction of the case or the mobile terminal. That is, the window glass 1000 of FIG. 8 has a wider viewing angle range than the window glass 1000 of FIG. 6, but the reflected light is skewed toward the side of the case or the mobile terminal. Hereinafter, the viewing angle range of the window glass 1000 of FIG. 8 will be described in detail with reference to FIG. 9C.

For convenience of explanation, the left direction is the first direction, the first direction, based on the virtual line P that is perpendicular to the surface on which the window glass 1000 is provided and passes through the end of the cover 1100 The opposite direction of is called the second direction. Here, the first direction may be a side direction of the case or the mobile terminal. Further, the second direction may be a center direction of the case or a center direction of the main body of the mobile terminal.

6 and 9(a), the window glass 1000 including the convex surface 1112a around the cover 1100 is 21 degrees in the first direction and 38 degrees in the second direction. It may have a viewing angle range (α). Here, the window glass 1000 has a thickness of 0.7 mm of the cover 1100, a width of the convex surface 1112a of 2 mm, and a depth of which the convex surface 1112a is formed is 0.4 mm. The window glass 1000 of FIG. 9A has a relatively narrow viewing angle range α.

7 and 9(b), the window glass 1000 including the first chamfer surface 1112b around the cover 1100 is 35 degrees in the first direction, and in the second direction. It may have a viewing angle range (α) of 72 degrees. Here, the window glass 1000 has a thickness of 0.7 mm of the cover 1100, a width of the first chamfer surface 1112b of 2 mm, and a depth of which the first chamfer surface 1112b is formed is 0.4 mm to be. The window glass 1000 of FIG. 9(b) has a relatively wide viewing angle range α as compared to the window glass 1000 of FIG. 9(a). The window glass 1000 of FIG. 9(b) reflects the reflected light skewed in the second direction, so that the reflected light can be more visually recognized when the mobile terminal is viewed from the front.

8 and 9(c), the window glass 1000 formed bent so that the end 1130 of the cover 1100 has a certain thickness along a predetermined curvature is 78 degrees in the first direction, It may have a viewing angle range α of 28 degrees in the second direction. Here, the width of the window glass 1000 is 8 mm and the height is 2.1 mm. The window glass 1000 of FIG. 9(c) reflects the reflected light skewed in the first direction when compared to the window glass 1000 of FIGS. 9(a) and 9(b), thereby fronting the mobile terminal. When viewed from, the reflected light cannot be recognized well.
