3 is an exploded perspective view of a portable terminal according to an embodiment of the present invention.

Referring to FIG. 3, a window mounting portion 128 is formed in the front gate 111. A plate-shaped window 130 is mounted on the window mounting portion 128. The window 130 is formed in a shape corresponding to the window mounting portion 128.

When the portable terminal has a touch screen function, the window 130 is provided with a touch sensing unit. The touch sensing unit may be formed in the form of a touch sheet or a touch film, and a conductive pattern of a conductive material may be formed on the touch sheet or the touch film. In this case, the window 130 may be electrically connected to the printed circuit board 140 by a flexible printed circuit board (FPCB) 141.

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

Referring to FIGS. 3 and 4, the window 130 includes a first region 131 and a second region 132 defined by the first region 131.

The first region 131 is formed so as not to pass light so as to cover the inside of the terminal body 110. The first area 131 is formed along the periphery of the window 130 so as to define an area where the time information of the display unit 113 is output. That is, the first region 131 may be formed in the edge region of the window 130.

The second region 132 is formed to allow light to pass from the outside to the inside of the terminal body 110 or from the inside to the outside of the terminal body 110. The second region 132 may include first through third light-transmissive regions 132a, 132b, and 132c disposed at a plurality of locations of the window 130. Although the first through third light transmitting regions 132a, 132b and 132c are located above the window 130 in the present embodiment, they may be formed at various positions that can be defined by the first region 131 .

A light processing module for processing light passing through the second region 132 is mounted inside the second region 132. As an example of the light processing module, an optical sensor that senses light that has passed through the second region 132 is exemplified. In the present embodiment, the proximity sensor 143 and the light intensity sensor 144 are examples of the light processing module.

The proximity sensor 143 senses that the object, for example, the user's face is approaching within a certain distance. The proximity sensor 143 includes a light emitting portion 143a that emits light toward an object and a light receiving portion 143b that receives light reflected from the object.

The light emitting portion 143a is disposed inside the first light transmitting region 132a and the light emitted from the light emitting portion 143a passes through the first light transmitting region 132a to reach an object.

The light-receiving portion 143b is disposed inside the second light-transmissive region 132b. Light that has been emitted from the light emitting portion 143a and arrives at an object is reflected and then reaches the light receiving portion 143b after passing through the second light transmitting region 132b.

It is possible to measure the distance from the proximity sensor 143 to the object through the time from when the light is emitted from the light emitting portion 143a to when the light reaches the light receiving portion 143b.

The portable terminal can be controlled so that the specific function is activated or deactivated by the sensing result of the proximity sensor 143. [

For example, when the portable terminal has a touch screen function, the portable terminal can be controlled so that the function of the touch sensing unit is inactivated when the user's face approaches within a predetermined distance from the window 130. Accordingly, the face of the user is contacted with the window 130 at the time of telephone conversation, and erroneous touch input can be prevented from occurring. In this case, when the user's face moves away from the window 130 by a certain distance, the portable terminal is controlled so that the function of the touch sensing unit is activated again.

The illuminance sensor 144 is configured to sense the brightness of light in an environment where the portable terminal is located, and is disposed inside the third light-transmitting region 132c. The illuminance sensor 144 measures the brightness of light passing through the third light-transmissive region 132c.

The portable terminal can be controlled so that the brightness of the display unit 113 is adjusted according to the sensing result of the illuminance sensor 144. For example, when the ambient brightness is low, the display unit 113 can be controlled so that the illuminance is lower than usual.

5 is a cross-sectional view of a window along the line V-V in Fig.

Referring to FIGS. 4 and 5, a first color layer 133 and a second color layer 134 are coated on one surface of a window 130 having a transparent material. Hereinafter, the first and second color layers 133 and 134 are applied to the rear surface of the window 130. FIG.

The first color layer 133 has an opaque material and is applied to the back surface of the first region 131 of the window 130. [ The first color layer 133 prevents light from passing through the first region 131 and provides a predetermined color to the first region 131.

The second color layer 134 has a light-transmitting material and is applied to the rear surface of the second region 132 of the window 130. The second color layer 134 has a color that can conceal the second region 132 in the first region 131 having the color of the first color layer 133. For this purpose, the second color layer 134 has a lower visible light transmittance than the window 130, and may additionally have the same or similar color as the color of the first color layer 133.

The second color layer 134 may include a plurality of color layers 134a, 134b, and 134c, respectively, which are applied to the rear surfaces of the first to third light-transmitting regions 132a, 132b, and 132c.

The second color layer 134 prevents the second region 132 from being exposed from the outside, thereby minimizing the influence of the second region 132 on the appearance of the terminal. The second color layer 134 prevents the electronic components inside the terminal, for example, the proximity sensor 143, the ambient light sensor 144, and the like from being visible from the outside through the second region 132 have.

6 is a cross-sectional view schematically showing a state where light passes through the second color layer.

Meanwhile, the light processing module, that is, the proximity sensor 143 and the illuminance sensor 144 are configured to be operated by light of a specific wavelength. The second color layer 134 has a light transmittance higher than a reference value at which the light processing module can operate. The reference values that can be operated for each type of light processing module may be different from each other, and accordingly, the light transmittance of the second color layer 134 may be different from each other. The light transmittance of the second color layer 134 can be adjusted mainly by color.

Therefore, when the proximity sensor 143 and the illuminance sensor 144 are operable differently from each other, the second color layers 134a and 134b applied to the inside of the first and second light-transmitting regions 132a and 132b, And the second color layer 134c applied to the inside of the third light-transmitting region 132c may have different colors.

The proximity sensor 143 may be configured to be operated by infrared rays. In this case, the second color layers 134a and 134b applied to the inside of the first and second light-transmitting regions 132a and 132b have an infrared transmittance higher than a reference value at which the proximity sensor 143 can operate. For example, if the reference value is 80% as shown in FIG. 6, the second color layers 134a and 134b applied to the inside of the first and second light transmitting regions 132a and 132b have an infrared transmittance of 80% or more. Here, the second color layers 134a and 134b may have a visible light transmittance similar to that of the first color layer 133. [

When the second color layer 134a coated on the inner side of the first light-transmitting region 132a has an infrared ray transmittance of 80%, 80% of the infrared ray emitted from the light-emitting portion 134a is incident on the first light- It passes. When the second color layer 134b applied to the inside of the second light-transmissive region 132b has an infrared transmittance of 80%, 80% of the infrared rays reaching the second light-transmissive region 132b are incident on the second color layer And reaches the light-receiving portion 143b.

The light intensity sensor 144 may be configured to be operated by visible light. Here, the second color layer 134c applied to the inside of the third light-transmitting region 132c has a visible light transmittance higher than a reference value at which the illuminance sensor 144 is operable. For example, if the reference value is 30%, the second color layer 134c applied inside the third light-transmitting region 132c may have a visible light transmittance of 30% or more. In this case, at least 30% of the visible light ray reaching the second color layer 134c applied to the inside of the third light-transmitting region 132c reaches the illuminance sensor 144.

As described above, the second color layer 134 prevents the second region 132 from being exposed to the outside as much as possible, and has a light transmittance higher than a reference value at which the light processing module can operate.
