Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device, and more particularly, to a communication device capable of identifying information by emission color.

[0002]

2. Description of the Related Art Heretofore, for example, in a wireless communication device, as a means for knowing a destination of a received radio wave, it has been confirmed by displaying a received frequency or a character corresponding thereto on an LCD display. Generally, in a wireless communication device having no LCD display, an LED indicating a reception state is generally turned on, and there is no way to confirm the communication destination.

[0003]

In the case of a communication device having an LCD display as described above, the reception frequency, characters corresponding thereto, a call registration number, and the like may be displayed on the LCD. In the case of a communication device provided only with LEDs that do not have them, it is particularly necessary to prepare another LED or separately provide means such as a speaker for calling by voice.

Recently, some pagers and the like have two or more types of call numbers. The call numbers are identified by a method of displaying the numbers on an LCD,
This is a method of changing the ring tone, and it is difficult for the user to recognize the distinction between numbers when "1" is emergency and "2" is normal, for example. Also, since the method of distinguishing by the ringing tone is audible, it is easy for an unfamiliar user to make an erroneous recognition, and a person who is usually performing identification by voice is switched to the mute mode. At times, it is sometimes difficult to identify by visual display.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to intuitively identify the reception frequency and calling number of a communication device in terms of luminescent color in view of the prior art.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to provide a backlight of an LCD display capable of switching light emission colors or an LED display capable of switching light emission colors, to provide two or more kinds of reception frequencies or two or more kinds of call registration. By providing a switching circuit for switching the emission color of the backlight or the emission color of the LED display corresponding to two or more kinds of frequencies or two or more kinds of identification codes according to a number or a reference set by a user. Achieved.

According to the above-mentioned means, two or more kinds of reception frequencies and call registration numbers are notified by switching the emission color of the backlight and the LED. In addition, the switching of the emission color can be applied simultaneously with the LCD display or the display by voice, whereby it is easy to make many distinctions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments.

FIG. 1 shows a communication device having an LCD display according to an embodiment of the present invention. Reference numeral 1 denotes an LCD display, and a backlight 2 is provided behind the display. The backlight 2 is a two-color light emitting LED provided on the printed circuit board 3.
4 and a backlight reflector 5. The emission colors of the LEDs 4 are, for example, two colors of red and green, and a switching circuit for switching the emission colors is provided on the board 3 in accordance with the reception frequency and the calling number.

FIG. 2 shows a two-color emission LE corresponding to a received signal.
6 shows a switching circuit that performs switching lighting control of D4. The radio frequency signal received by the antenna 11 is amplified, detected, and demodulated by the radio unit 12. The demodulated signal is decoded by the waveform shaping circuit 13. The decoded signal is read by the decoder 14. The decoder 14 includes a one-chip CPU (Central Processing Unit), and a P-ROM (Programmable Read).
And the waveform shaping circuit 13 of data of two or more types of call numbers written in advance in the Only Memory 15 in advance.
The received call number is received through the input port, the two are compared, and if the received number matches one of the P-ROMs 15, a signal corresponding to the data of the call number is output through the output port to the LCD control / driver. 16 to drive the LCD 1 to display the number.

For example, in the case of an emergency call, "1" is displayed, and in other cases, "2" is displayed.

Next, a number corresponding to the received call number is displayed on the LCD 1 and the LED 4 is used to switch the light emission color of the backlight. That is, the decoder 4
When the emergency call number "1" is displayed on the LCD 1, a signal is simultaneously output from the output boat to the amplifier 17, the red LED 41 is turned on, and the LCD backlight emits red light. If the incoming call number is other than emergency,
When "2" is displayed on the CD1, the decoder 4 outputs a signal to the amplifier 18 to turn on the green LED 42 and make the backlight emit green light.

As described above, the light emission color of the backlight of the LCD is switched according to the reception call number to emit light.
In addition to the display of characters such as numbers, the received call numbers can be easily and intuitively distinguished and recognized by a light emitting backlight.

The reset switch 19 is connected to the decoder 1
4 for controlling display, stopping light emission, and controlling redisplay.

The identification of the information by the emission color is not limited to the call registration number, but according to the frequency of the received signal, two or more kinds of frequencies according to a reference set by the user, or two or more kinds of identification codes. The backlight emission color can be switched according to the individual identification code.

In a communication device having an LED display, the display frequency and the identification code of the received signal can be easily displayed and confirmed by switching the emission color of the LED display instead of the backlight. .

In the case of a communication device having an LCD,
The reception frequency, characters corresponding to the reception frequency, a call number, and the like may be displayed on the LCD, but in the case of a communication device having no LCD, a method such as providing an LED or distinguishing by voice is used. Also in this case, information can be easily and intuitively identified by combining the light emission of the backlight or the light emission of the LED display for switching the light emission color as described above.

Further, the light emission color of the backlight can be arbitrarily selected, and it is possible to perform switching light emission of two or more colors.

[0019]

According to the present invention, as described above, the receiving frequency, the call registration number, the identification code, etc. can be intuitively displayed by the luminescent color without displaying on the LCD or discriminating by voice. Can be easily identified. Further, by applying the light emission of switching the emission color simultaneously with the identification by the LCD display or the voice, more accurate identification display can be performed.

Further, according to the present invention, even if the main body of the communication device is located at a slightly distant place and the LCD display cannot be read clearly, there is an effect that the recognition based on the emission color can be easily performed.
