4 is a perspective view of the window shown in Fig.

Referring to FIG. 4, a light processing unit for processing light passing through the light transmitting area 211 for the light processing module is inserted and fixed in the window 210. As an example of the light processing unit, an optical sensor for sensing light in the second region 132 may be used. In this embodiment, the proximity sensor 240 and the illuminance sensor 250 are described as an example of the light processing unit. However, the light processing unit may be implemented in any form if it is a device for processing light to operate a specific function of the mobile terminal.

The proximity sensor 240 senses that an object, for example a user's face, is approaching within a certain distance, and the illuminance sensor 250 is configured to sense the brightness of the surrounding environment in which the mobile terminal is located.

The window 210 is formed with first and second mounting holes 240a and 250a for mounting the proximity sensor 240 and the illuminance sensor 250, respectively. The proximity sensor 240 and the illuminance sensor 250 may be integrally formed. In this case, one mounting hole is formed.

5 is a cross-sectional view of the proximity sensor according to the line V-V in FIG.

In this description, the proximity sensor 240 is described as an example for explaining the configuration of the light processing unit, but the same can be applied to other types of light processing units.

The proximity sensor 240 includes a case 241 constituting an appearance of the proximity sensor 240 and a light processing module 242 composed of a light emitting portion 243 and a light receiving portion 244.

The case 241 may be formed to correspond to the first mounting hole 240a so as to be fitted into the first mounting hole 240a. The case 241 may be mounted to the first mounting hole 240a through various methods as long as the case 241 can be inserted and fixed in the first mounting hole 240a as well as the method of fitting into the first mounting hole 240a .

The light emitting portion 243 is disposed inside the first light transmitting region 212 and the light emitted from the light emitting portion 243 passes through the first light transmitting region 212 to reach an object.

The light-receiving unit 244 is disposed inside the second light-transmissive area 213. After the light emitted from the light-emitting unit 243 reaches the object, the reflected light passes through the second transmissive area 213, .

It is possible to measure the distance from the proximity sensor 240 to the object through the time from when the light is emitted from the light emitting portion 243 to when the light reaches the light receiving portion 244.

The mobile terminal can be controlled such that the specific function is activated or deactivated by the sensing result of the proximity sensor 240. [

For example, when the mobile terminal has a touch screen function, the mobile terminal can be controlled so that the function of the touch sensing unit is inactivated when the face of the user approaches the window 210 within a predetermined distance. Accordingly, the face of the user can be prevented from being in contact with the window 210 during the telephone conversation, and the erroneous input of information can be prevented from occurring. In this case, when the user's face moves away from the window 210 by a certain distance, the mobile terminal is controlled so that the function of the touch sensing unit is activated again.

A flexible circuit board 245 is mounted on the outside of the case 241 and the flexible circuit board 245 electrically connects the light processing module 242 and the printed circuit board inside the terminal body. At this time, the flexible circuit board 245 can be inserted into the terminal body through the through hole 225 of the window mounting surface 221 (see FIG. 3).

The flexible circuit board 245 may be electrically connected to the light processing module 242 by connection terminals 243a and 244b penetrating the case 241. [

The configuration of the proximity sensor 240 has been described above. This configuration can also be applied to the illuminance sensor 250 as well. However, the illuminance sensor 250 includes only the light receiving portion inside the case 251 (see FIG. 7). The light receiving portion is located inside the third light transmitting region 214, and the light receiving portion receives light passing through the third light transmitting region 214.

The mobile terminal can be controlled so that the brightness of the time information output from the display unit 151 is adjusted according to the sensing result of the illuminance sensor 250. [ For example, when the ambient brightness is low, the display unit 151 can be controlled so that the luminance is lower than usual.

6 and 7, the first mounting hole 240a is formed to a predetermined depth from the back surface of the window 210, and the case 241 is formed in the first mounting hole 240a toward the front of the window 210 .

The proximity sensor 240, specifically the case 241, provides a mounting surface for attachment to the window mount 220 along with the window 210. The bottom surface of the case 241 may be substantially coplanar with the back surface of the window 210 so as to form an attachment surface together with the back surface of the window 210. [

An adhesive film 266 may be attached to the attachment surface formed by the back surface of the window 210 and the bottom surface of the case 241. The adhesive film 266 may be modified into various forms such as an adhesive, an adhesive sheet, and an adhesive tape. The adhesive film 266 has a shape corresponding to the window attachment surface 221 and may have a through hole 267 through which the flexible circuit board passes. The window 210 can be attached to the window mounting surface 221 with the adhesive film 266 attached thereto.

This configuration is also applied to the case of the illuminance sensor 250, and a description thereof will be omitted.

When the mobile terminal has a touch screen function, the window 210 may include a base 261, a touch sheet 262, and a protective sheet 263 as shown in FIGS.

The base 262 provides rigidity to the window, and may be formed of a transparent synthetic resin or tempered glass. In this embodiment, the first and second mounting holes 240a and 240b are formed in the form of through holes passing through the base 262, but they may be formed only to a certain depth of the base 262. [

The touch sheet 262 is attached to one surface of the base 262 and senses the touch by an electrical signal generated according to a user's touch. When the touch sheet 262 is attached to the front surface of the base 262, an adhesive film 266 is attached to the back surface of the base 262.

The protective sheet 263 is attached to one surface of the touch sheet 262 to protect the touch sheet 262. The protective sheet 263 may be coated on the outer surface of the touch sheet 262 as well as in the form of a sheet.

The first and second color layers 264 and 265 may be provided on the rear surface of the protective sheet 263. The first color layer 264 is opaque and forms the opaque region 212 of the window. Then, the second color layer 265 can be applied to the light transmitting region as a light transmitting property. The second color layer 265 may have a color similar to that of the opaque region, thereby preventing the visible region from becoming conspicuous.

As described above, according to the present invention, the light processing unit can be disposed as close as possible to the outer surface of the terminal through the structure in which the light processing unit is inserted into the window. Thus, the operating environment of the light processing unit can be greatly improved. That is, as the proximity sensor 240 and the illuminance sensor 250 are as close as possible to the outer surface of the mobile terminal, the sensing sensitivity of the proximity sensor 240 and the illuminance sensor 250 can be improved.

For example, when the proximity sensor 240 has a sensing distance of a predetermined value, the proximity sensor 240 is close to the outside of the terminal, thereby improving the operating environment of the proximity sensor 240.

In addition, since the light processing unit forms the mounting surface together with the window 210, the window 210 can be stably attached to the window mounting surface 221 even though the mounting hole is formed. That is, it is possible to prevent the window from being firmly attached or lifted due to the reduction of the bonding area due to the formation of the mounting holes 240a and 250a.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
