The antenna 116, which forms part of the broadcast receiving module 111 (see FIG. 1), can be installed to be able to be drawn out from the terminal body.

3 is an exploded perspective view of the front case 101 and the glass window 105 of the mobile terminal according to an embodiment of the present invention, Figure 4 is a display lamp 200 of the mobile terminal according to an embodiment of the present invention. It is sectional drawing. 3 and 4, the glass window 105, the bezel 106, the front case 101, the white layer 210, and the display lamp 200 are illustrated.

The front case 101 is a case covering the front surface of the mobile terminal as described above, and has a through window formed so that the display unit 151 is exposed on the front surface. The through-window is formed larger than the active area (the area where the screen is displayed) of the minimum display unit 151, and in some cases, is formed larger than the display unit 151, so that the camera 121, the sound output unit 152, etc. Can be located.

The glass window 105 is coupled to the front surface of the front case 101 to cover the through-window 101a. The portion where the sound output module 152 is located may form an opening.

The bezel 106 is positioned between the glass window 105 and the front case 101 to cover internal components excluding the active areas of the front case 101 and the display unit 151. It is made of an opaque material so that the inside is not visible, and is generally formed by printing on the glass window 105.

Printing can be performed multiple times to block light transmission. Portions through which light must pass, such as the camera 121 or the sensor 141, may form openings in the bezel 106.

The light transmitting portion 106a is a portion where the display lamp 200 is positioned, and when viewed from the front side, it is similar to other portions, but is thinner than the bezel 106 of the other portion so that the light of the display lamp 200 is emitted to the front surface. .

If an opening is formed in the front surface such as a portion where the camera is formed, there is a problem that the display lamp 200 is visible to the eyes of the user even when the display lamp 200 is not turned on. Therefore, a smog printing method may be used in order to be thinner than the bezel 106 of the other part and to be indistinguishable from the front while transmitting light.

The display lamp 200 is located at the rear of the glass window 105 and is disposed to face the light transmitting part 106a. Different colors of the light emitting devices 201, 202, and 203 may be displayed to display different states of the mobile terminal according to the color.

It may be coupled to the front case 101 as shown in Figure 4 to secure to the light transmitting portion (106a). The front case 101 may further include a lamp hole 1011 on which the display lamp 200 may be mounted.

The lamp hole 1011 may be formed by simply drilling a hole in the front case 101, or may be formed to protrude in the rear direction as shown in FIG. The display lamp 200 is fixed to the end of the lamp hole 1011 to face the light transmitting part 106a.

The display lamp 200 indicates whether the USIM card or the memory card is installed or not, and indicates whether the mobile terminal is in normal operation. A plurality of display lamps 200 may be required according to the diversification of functions, but in this case, the display lamp 200 collides with the problem of space limitation of the mobile terminal. As shown in FIG. 203 may be mounted on one display lamp 200, and different states may be displayed according to colors.

The display lamp 200 may use light emitting diodes 201, 202, and 203 in consideration of size, durability, brightness, and the like. Since the light emitting devices 201, 202, and 203 have high light intensity, when the light emitted from the display lamp 200 passes through the light emitting unit 106a, the light is emitted in the form of a point light source.

When the light is emitted in the form of a point light source, only a portion of the display lamp 200 becomes excessively prominent, so it is necessary to make the light more smoothly. In addition, when the plurality of light emitting devices 201, 202, and 203 are used as shown in FIG. 3, since the positions of the light emitting devices 201, 202, and 203 are different, light is emitted from the front side according to the light emitting devices 201, 202, and 203. This injection position is different.

Therefore, the present invention uses the white layer 210 to allow the light emitted through the one light transmitting unit 106a to be uniformly spread throughout the light transmitting unit 106a without being seen as a point light source.

The white layer 210 is a scattering layer positioned between the light transmitting unit 106a and the display lamp 200 and is a thin white member for scattering. The white layer 210 may be printed on the rear surface of the light transmitting unit 106a in white, or a member having a separate sheet shape may be used as shown in FIG. 4.

In the former case, since the printing is performed in a small area, there may be a variation in the printing thickness, thereby causing a variation in the transmittance. In addition, white printing may cause visual differences with the bezel 106 region on the front surface. In the latter case, light of the display lamp 200 may be emitted with a uniform transmittance by inserting a sheet of white color having a uniform light transmittance.

The white layer 210 may use a white print on a transparent film. In this case, the white print is thinly formed only once because light must be transmitted. Considering the transmittance of light, it can be formed to a thickness of about 1μm or more and 10μm or less.

The light passing through the white layer 210 is weakened in intensity, but is scattered to uniformly supply light to the entire transparent part 106a. Therefore, even if there is a position difference between the light emitting elements 201, 202, and 203, the user cannot recognize the difference.

The lamp hole 1011 may include a stepped portion 1012 so that the white layer 210 may be seated. As shown in FIG. 4, the stepped part 1012 may be formed to have a narrower side of the light transmitting part 106a, or may be formed to have a narrower side of the display lamp 200. The white layer 210 of the small size may be stably coupled to the lamphole 1011 by seating the white layer 210 on the stepped portion of the stepped portion 1012.

As described above, according to at least one of the exemplary embodiments of the present invention, light is scattered so that the point light source of the display lamp is emitted to the surface light source, and thus the light of the display lamp may be emitted without being too splashed.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
