Description

  The present invention relates to a light emitting display structure and a mobile terminal device for notifying an incoming call or the like by a light emitting display.

  Many portable terminal devices such as mobile phones are provided with a light-emitting display structure for notifying an incoming call or alarm by emitting light when a call or e-mail is received or when an alarm is activated. . On the other hand, mobile terminal devices such as mobile phones are rapidly becoming thinner and smaller, and the number of cases where the light-emitting display structure cannot be installed in a place with high visibility is increasing due to restrictions on the mounting layout.

  A mobile phone related to the present invention will be described with reference to FIGS. 9 and 10 are perspective views showing the external appearance of the foldable mobile phone. 11 is a cross-sectional view taken along line AA showing the light-emitting display structure of the foldable mobile phone shown in FIG.

  In the foldable mobile phone shown in FIG. 9, a light emitting display structure is provided in the upper center of an upper casing provided with a display portion. This light-emitting display structure includes a light-emitting display lens 1 and an LED (Light Emitting Diode) 4, and the light-emitting display fixed to the inside of the housing 2 as shown in the AA cross-sectional view of FIG. The light-emitting display unit 1a that is a part of the lens 1 is exposed between the housing surface 2a and the housing surface 2b (the exposed surface is flush with the housing surface 2a and the housing surface 2b). ). And it has the structure where the light emitted from LED4 mounted in the printed circuit board 3 light-emits by the light emission display part 1a through the light guide part 1b.

  Further, in the foldable mobile phone shown in FIG. 10, by arranging the light emitting display portion 1a at the corner of the upper housing, it is possible to increase the number of surfaces on which the light emitting display can be confirmed.

As a technical example related to the present invention, as a power switch, a push button switch in which the distance between the switch cover and the switch body changes between an on state and an off state is used, and the switch cover protrudes from the case in the on state. In addition, there is a “wireless communication device” in which a switch cover is housed in a case in an off state and a power switch also serves as an incoming call lamp (see, for example, Patent Document 1).
JP-A-8-32657

  However, in the light-emitting display structure of the mobile phone shown in FIG. 9, the light-emitting display unit 1a has a structure extending over two surfaces (X, Y), so that light emission can be confirmed from two directions. From the four sides (four directions), there was a blind spot, and there was a problem that the luminescent display could not be visually recognized.

  In the light emitting display structure of the mobile phone shown in FIG. 10, the direction in which the light emitting display can be confirmed is larger than that in FIG. 9, but since the light emitting display lens installed at the corner of the upper housing becomes larger, There was a problem that it was necessary to secure the installation space.

  In addition, the wireless communication device described in Patent Document 1 has a structure in which a power switch that also serves as an incoming call lamp protrudes from the case when the power is turned on. The power supply may be turned off without following the user's intention, and it is difficult to say that the light-emitting display such as the incoming call lamp can be viewed at all times. Generally, when a mobile phone or the like is not used, it is often left in a standby state without being turned off, and the mobile phone is not frequently switched on and off. Therefore, in a mobile phone with many power-on states, it is desirable to have a structure in which a light-emitting display such as an incoming call lamp can always be visually recognized regardless of whether the power is on or off.
