[Embodiment of the invention]

 Hereinafter, embodiments of a display device for a mobile phone and a mobile phone according to the present invention will be described with reference to the drawings. FIG. 1 is a view for explaining an embodiment of a display device for a mobile phone, which is a block diagram of the display device, FIG. 2 is a schematic external view of the display device attached to the mobile phone, and FIG. FIG. 4 is a schematic diagram for explaining a modified example of the EL light source of the device, FIG. 4 is a diagram for explaining another embodiment of the device, and a schematic external view of the device, and FIG. FIG. 3 is a view for explaining the embodiment, and is a schematic external view of the airplane.

The display device 1 for a mobile phone described here receives an incoming call through the antenna 21 of the mobile phone 2, an antenna 10 for receiving a carrier signal or the like transmitted at the time of an incoming call or a call, and the signal is input through the antenna 10. Then, a driving circuit 20 that generates a current and a linear EL light source 30 that is supplied with the current output from the driving circuit 20 and blinks (or lights) are provided.

The antenna 10 not only receives a carrier signal or the like, but also functions as a connector 50 for connecting the mobile phone 2 and the apparatus main body 40. Here, metal wires are used. That is, the tip of the antenna 10 protruding from the device main body 40 is connected to the hand strap attachment port 22 of the mobile phone 2.

The drive circuit 20 includes a detection circuit 21 composed of a diode or the like that detects a carrier signal or the like received by the antenna 1 and a multivibrator 22 that operates at the falling edge of the output signal of the detection circuit 21. And a circuit centered on a blocking oscillator and an EL driver which operate in response to an output signal of the multivibrator 22, for generating a pulse voltage (100 to 220 PPV) to blink the EL light source 30. And an inverter circuit 23 that outputs a current (several tens of mA). Such a drive circuit 20 is built in the apparatus main body 10 together with a battery (not shown) for supplying a power supply voltage.

The apparatus main body 10 is a resin container for protecting the drive circuit 20 and the like. The outer shape and material are not limited as long as the drive circuit 20 and the like can be protected. For example, accessories such as a human figure and the like may be used. good.

The EL light source body 30 uses a cable-like EL (electroluminescence) light source. When a voltage is applied between internal electrodes surrounded by a dielectric and an electric field is generated, a specific color is generated by excitation of electrons. Light is generated, and the light is radiated evenly in the entire circumferential direction. In order to use such an EL light source body 30 as a hand strap, both ends thereof are attached to the outer surface of the apparatus main body 40. In addition, EL light sources of various colors are commercially available.

The operation of the display device 1 for a mobile phone configured as described above will be described. When the mobile phone 2 is in a calling incoming call state or a talking state and a carrier signal or the like is transmitted from the antenna 21 of the mobile phone 2, the carrier signal is received by the antenna 10, and the inverter circuit 23 is operated for a predetermined time through the detection circuit 21 and the multivibrator 22. Operates at intervals. When the inverter circuit 23 is operating, a pulse voltage is output, so that the EL light source 30 is turned on. When the inverter circuit 23 is not operating, no pulse voltage is output, and the EL light source 30 is turned off. Does not light. When a carrier signal or the like is not transmitted from the antenna 21 of the mobile phone 2, the multivibrator 22 and the inverter circuit 23 do not operate.

In short, when the mobile phone 2 enters the incoming call receiving state or the talking state, the EL light source 30 blinks at a predetermined time interval. As long as the hand strap itself, which is the EL light source body 30, flickers, it becomes very noticeable in terms of the light emitting area and the like. The EL light source 30 is not limited to the colors of red, blue and green, but also has various colors such as intermediate colors.

The use of an EL light source 30 ′ as shown in FIG. 3 is more effective. The EL light source body 30 'in the illustrated example has a configuration in which two EL light sources 31 and 32 of different colors are provided at an interval inside a transparent body 33 such as a resin. Such an EL light source 30 'emits light in three colors. That is, although the EL light sources 31 and 32 emit light of different colors, the portion of the transparent body 33 located between the EL light sources 31 and 32 is different from the above due to the overlap of the light emission of the EL light sources 31 and 32. Emit light in different colors. In this case, the light emission of the EL light source body 30 'is very beautiful, and it becomes more conspicuous in terms of color arrangement. The number of the EL light sources may be three or more, and the whole or a part may be formed in a spiral shape.

In the above-described display device 1 for a mobile phone, the device main body 40 and the mobile phone 2 are connected using the antenna 10. As a result, not only is the device body 40 and the mobile phone 2 firmly connected, but also the distance between the antenna 10 and the antenna 21 of the mobile phone 2 is kept constant. Will operate stably.

However, instead of providing the antenna 10 inside the apparatus main body 40, a string, a clip, or the like may be used as the connector 50, and the apparatus main body 40 and the mobile phone 2 may be connected in the same manner as described above. I don't care. When the metal device main body 40 is used, the device main body 40 itself can be used as the antenna 10.

In the display device 1 for a mobile phone described above, the device main body 40 can be connected to the mobile phone 2, but as shown in FIG. 4, it is configured as a completely independent device. It doesn't matter. That is, the antenna 10 and the drive circuit 20 are provided inside the apparatus main body 40 'which is a resin container, and both ends of the EL light source body 30 (or 30') are connected to the outer surface of the apparatus main body 40 'as hand straps. To do it. Even in this case, when the mobile phone 2 enters the incoming call receiving state or the talking state, the EL light source 30 blinks in the same manner as described above.

Further, a form in which the function as the display device 1 for a mobile phone is realized by a mobile phone may be adopted. FIG. 5 is a schematic diagram of a mobile phone. Here, the EL luminous body 30 (or 30 ′) is used as a hand strap of the mobile phone 3. Then, when the mobile phone 3 enters the incoming call receiving state or the talking state, the light emitting diode and the vibrator provided in the mobile phone 3 operate, but instead of activating this, the EL luminous body 30 is made to blink. Even in this case, the same effect as the display device 1 for a mobile phone can be obtained.

The display device for a mobile phone and the mobile phone according to the present invention are not limited to the embodiments described above, and may be modified as follows. For example, the antenna may be provided not only on the outer surface of the device main body or inside the device but also on the EL light source. As the driving circuit, any type of driving circuit may be used as long as it can emit or blink the EL light source when the mobile phone is in a ringing incoming call state or a talking state. The EL light source may be of any type as long as it has a linear shape and can emit light in the entire circumferential direction. In using the EL light source body as a hand strap, only the end of the EL light source body may be connected to the apparatus body or the like. In addition, the mobile phone here includes not only a so-called mobile phone but also a PHS and the like.
