Output. A UHF radio signal received by the antenna 1 is input to the UHF receiving circuit 6 via the duplexer 2 and the transmission / reception selector switch 17. The UHF receiving circuit 6 amplifies the input radio signal with low noise, performs low-frequency conversion (down conversion) and demodulation, outputs the demodulated audio signal to the speaker 8, and receives the audio of the received audio signal Output.

  A CPU (central processing unit) 10 controls the operation of the wireless communication device and the display of the LCD 20, and also controls the PWM driver 21 to control the color, brightness, and lighting time of the LCD backlight full-color LEDs 31 to 38. The CPU 10 is, for example, a flash memory, an EEPROM 11 that stores an operation program, a display control program, display control data, and the like of the wireless communication device, a RAM 12 that stores temporary operation data, a use band, a use channel, and display control. A keyboard 13 for inputting user instruction data such as data, a USB interface 14 for receiving display control data via a USB connector 18 detachable from the personal computer 50, and a transmission key for the user to instruct transmission 15, the LCD 20, and the PWM driver 21 are connected. Note that display control data (for example, file data created by spreadsheet software) from the personal computer 50 is stored in the EEPROM 11 as display control data. The display control data is also created and stored by the user using the keyboard 13.

  When the transmission key 15 is turned on, the CPU 10 switches one of the selected bands of the transmission / reception change-over switches 16 and 17 to the transmission (TX) side, while when the transmission key 15 is turned off, the transmission / reception switching is performed. The switch (one of 16 and 17) is switched to the reception (RX) side. The CPU 10 performs control so that the currently used VHF frequency and UHF frequency are displayed side by side on the LCD 20. Further, the CPU 10 performs PWM control (pulse width modulation) on each of the RGB drive voltages of the LCD backlight full-color LEDs 31 to 38 based on display control data in the EEPROM, thereby dividing the LCD 20 into eight in the horizontal direction. With respect to the portions thus obtained, the color, brightness and lighting time of each portion can be arbitrarily controlled. An example of the display control mode using the display control data will be described below with reference to FIG.

  FIG. 2 is a diagram showing an example of the display control mode of the LCD 20 of the wireless communication apparatus of FIG. In FIG. 2, display before and after an event according to a user instruction on the LCD 20 (the number on the left is the VHF frequency (MHz), the number on the right is the UHF frequency (MHz), and the colors of the LCD backlight full-color LEDs 31 to 38 and Brightness), the color in the display (the color from the left of the display, for example, the light blue “color” is omitted), and the like.

  In the event of the standby state in the mode M1, each band of UHF / VHF can be expressed by a backlight of a different color, and a user's favorite color can be selected and displayed.

  In mode M2, instead of using a signal intensity meter at the time of reception of a radio signal, the backlight color gradation (shading) is changed according to the signal intensity, so that it can be made easier to understand visually.

  In mode M3, when high power transmission is performed with VHF, the backlight of the VHF display area displays the power value of the transmission power meter. Here, the color gradation (shading) is changed depending on the power value.

  In mode M4, a temperature rise is displayed. For example, the fact that the body temperature is rising due to continuous transmission or the like is indicated by a color, thereby warning the degree of danger more strongly. Furthermore, if the backlight is blinked, the effect is further increased.

  In mode M5, the memory channel is displayed in color. Since a color can be assigned to each memory channel number, it is possible to determine which memory channel is based only on the color of the backlight. Here, the memory channel means that the frequency of each band is stored in advance for each of a plurality of memory channels, and the frequency is specified by specifying the memory channel number.

  In mode M6, “scanning” is displayed to scan the reception frequency of the radio signal. In FIG. 2, the color is changed for each band in the order of red, yellow, green, blue, and red (hereinafter, repeated), and the color display position is moved to the right. By turning each backlight on in order by changing the color, it becomes a flowing display, and it is easier to understand that scanning is in progress. This example shows a case where scanning is performed in steps of 20 KHz.

The wireless communication apparatus according to the embodiment configured as described above has the following specific effects.
(1) Since the color of the backlight can be freely set, a user's favorite color can be selected (see, for example, display mode M1).
(2) Since a color can be assigned to each memory channel, for example, when the memory scan is stopped, it is possible to determine which memory channel is based on only the color (for example, refer to the display mode M5). In this case, there is no need to see the memory channel number or memory name.
(3) Since each color and brightness | luminance of each full color LED31-38 for each backlight can be set freely, a visual effect is high and aesthetics are high (for example, refer to display modes M1 and M5).
(4) When eight full-color LEDs 31 to 38 for backlight are used instead of the signal intensity meter, the entire display becomes a signal intensity meter (for example, see display mode M2). Similarly, at the time of transmission, it becomes a transmission power meter (for example, see display mode M3).
(5) If each color and lighting time of each backlight full-color LED 31 to 38 are programmed, a display in which a rainbow color flows is also possible. In this case, the red, orange, yellow, green, light blue, blue, and purple bands are displayed so as to flow in the right direction (see, for example, display modes M6 and M7).
(6) The temperature when the main body temperature rises by continuous transmission can be displayed (see, for example, display mode M1).
(7) The color, brightness, and lighting time of each backlight full-color LED 31 to 38 are created in a spreadsheet software table, and the user can freely create a dynamic color expression by reading the file.

  In the above embodiment, the backlight full-color LEDs 31 to 38 are juxtaposed in the horizontal direction or the horizontal direction as an example on the back surface of the LCD 20, but the present invention is not limited to the one-dimensional direction, and a plurality of backlights are arranged in the two-dimensional direction. The light full-color LEDs may be juxtaposed to control at least one of the position, color, brightness, and lighting time of each backlight full-color LED.

  In the above embodiment, the transmission / reception frequency of each band is displayed on the LCD 20, but the present invention is not limited to this, and other predetermined display information such as a channel number may be displayed.

  In the above embodiment, the backlight full-color LEDs 31 to 38 are used. However, the present invention is not limited to this, and other types of display elements such as an organic EL display element and a plasma display element may be used.
