Hereinafter, a mobile phone according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic block diagram showing a configuration of a mobile phone 1 having a key backlight according to an embodiment of the present invention.
The mobile phone 1 includes a main display 101, a key operation unit 102, and an open / close detection device 103 as user interfaces. As the open / close detection device 103, for example, a Hall IC is used. The Hall IC is provided with a magnet at an opposite position when the cellular phone 1 is in a closed state, and the cellular phone 1 is connected to the Hall IC based on whether or not the magnet has approached within a predetermined distance. It detects that the state has changed from the closed state to the open state. This detection result is output from the open / close detection device 103 to the control unit 105 as a signal indicating that it has shifted to the open state. When the mobile phone 1 is foldable, the open / close detection device 103 detects that the mobile phone 1 is opened from the folded state. When the mobile phone 1 is slidable, the open / close detection device 103 detects that the mobile phone 1 is opened by sliding. .

The key backlight 104 has a plurality of light sources arranged on the lower surface (inside the main body) of the key operation unit 102 and illuminates the key operation unit 104 from the back side.
The control unit 105 performs control to turn on the key backlight 104 and display control of the main display 101. The control unit 105 controls lighting of individual light sources (R, G, B) of the key backlight 104 according to the lighting pattern data stored in the storage unit 109.
In addition, the mobile phone 1 communicates with a wireless communication unit 107 that performs data communication between the mobile phone 1 and a network server, an infrared communication unit 106 that performs data communication between mobile phones and other transmission / reception terminals using infrared rays, and an IC chip. An IC communication unit 108 is provided.
The storage unit 109 stores lighting pattern data. The lighting pattern data is data for controlling the lighting pattern of the key backlight. The lighting pattern is data for controlling each of the R, G, and B lighting elements of the light source with respect to whether or not lighting is performed, the luminance when the lamp is lit, and the lighting time. This lighting pattern data is read by the control unit 105.

FIG. 2 is a diagram showing the arrangement of the lights 202 that constitute the key backlight 104. The key backlight 104 is composed of a plurality of lights 202. The light 202 is a light source composed of three lighting elements (R (Red), G (Green), and B (Blue)), and each terminal (R, G) of the light 202 corresponding to each terminal of the control unit 105. , B) are connected. The light 202 is provided with a power supply terminal. The light 202 is supplied with power from the control unit 105 or a battery in the mobile phone 1 and supplied to each lighting element.
The brightness and lighting time of the lighting elements (R, G, B) can be arbitrarily set within a predetermined pattern by the control unit 105 by the user, and the brightness and lighting time are controlled by the control unit 105 according to the set contents. Be controlled. This setting content is stored in the storage unit 109 as lighting pattern data.
Here, the mounting position and the number of lights 202 constituting the key backlight 104 can be arbitrarily changed within the mounting conditions such as area. In this embodiment, a case where there are three in the horizontal direction and seven in the vertical direction and a total of 21 lights 202 are arranged will be described as an example.

  FIG. 3 is a diagram for explaining a flow in which the user creates a lighting pattern independently and transfers the data to the mobile phone 301. Here, the database 302 and the PC 303 are connected via a communication line such as the Internet. Further, the PC 303 and the mobile phone 1 are communicably connected via a communication line. Further, the mobile phone 1 has a function of reading data stored in the recording medium 304 and downloading it from the database 302.

First, the PC 303 accesses the database 302 on the network based on an instruction input from the user via an input device such as a keyboard and downloads the key illumination creation tool 305 via the communication line (procedure 1).
The key illumination creation tool 305 (lighting pattern data generation unit) is a tool (program) that allows the user to determine the key backlight lighting pattern by being executed in the PC 303. After the user downloads the key illumination creation tool 305, the user executes the key illumination creation tool 305 on the PC 303 to create lighting pattern data as the key illumination content 306.

  When the key illumination content 306 is created using the key illumination creation tool 305 (procedure 2), the key illumination content 306 is transmitted via the recording medium 304 or the database 302 on the network (procedure 3) to the mobile phone. 1 (procedure 4). Here, the mobile phone 1 accesses the server device having the database 302 by the wireless communication unit 107 and downloads the lighting pattern data.

Next, key backlight lighting control will be described.
When the lights 202 constituting the key backlight 104 are independently controlled, an example of a control method of the control unit 105 is PWM (Pulse Width Modulation) control. Each light 202 includes three lighting elements of R, G, and B, and each terminal of the control unit 105 and each terminal of the light 202 are connected.
The lighting elements (R, G, B) can be arbitrarily set with luminance and lighting time by the control unit 105, and are controlled to light according to the luminance and lighting time. Each light 202 can be lit in an arbitrary color according to the luminance ratio of each of the lighting elements (R, G, B) constituting the light 202. That is, a single light 202 can express a plurality of colors composed of RGB mixed colors. The control unit 105 controls all the lights 202 constituting the key backlight independently. Thereby, it is possible to realize a lighting pattern with a high degree of freedom.

FIG. 4 is a diagram illustrating an example of a lighting pattern of the key backlight 104. A plurality of lights 202 (for example, R, G, and B LEDs) constituting the key backlight 104 that illuminates the key operation unit 102 of the mobile phone 1 are arranged, and each light 202 can be independently controlled.
Here, for example, the colors A to E of each light are determined by the ratio of the luminance of each of R, G, and B of the light 202. Each light 202 is independently controlled so that each light is turned on so as to have a different color (here, color A to color E), luminance, and lighting timing. This realizes key backlight control with a high degree of freedom.

Next, a scene using key backlight independent lighting (key illumination) will be described.
(1) Key illumination in conjunction with opening and closing of a folding mobile phone In this embodiment, the key backlight 104 shines in various lighting patterns when the casing is opened. It is used as illumination.
The lighting pattern that is turned on when the housing is opened can be arbitrarily set by the user, and the user can enjoy the set illumination every time the housing is opened. The user can also set the lighting pattern to his liking. This lighting pattern can also be set at random. From the lighting patterns prepared in advance, the lighting pattern is selected at random each time the casing is opened, and the illumination is turned on according to the selected lighting pattern. After the illumination lighting ends, in preparation for key operation, the control unit 105 switches to lighting that makes it easy to see key printing (button numbers and symbols) (for example, each light 202 lights in a unified color).

Next, a lighting pattern of key illumination (lighting pattern that can be realized by independent control of the key backlight) will be described. Examples of the lighting pattern include the following patterns (1) to (5).
(1) Lighting with movement (Change the setting of the number of frames specified per second to realize a lighting pattern with movement)
(2) Illuminated with a unified color on the entire surface (R, G, B brightness can be set, so various colors can be set by blending colors)
(3) Gradation (setting where the color and brightness of adjacent lights change smoothly and continuously)
(4) Random (The color and brightness of each light are selected at random)
(5) Represent pictures (icons), numbers, and letters (represent shapes by selecting lighting points)

As an application example of the above (1) to (5), (1) an example of gradation lighting with movement will be described.
Gradation lights in red gradually from the upper part of the key (near the operation key), and gradation gradation lights gradually in blue from the lower part of the key (near the number 0 key). The moving red and blue gradations are mixed in the center of the key (near the number 2 key), and gradually change to an uneven color (red and blue are lit). This expresses a moving gradation.

As for the lighting pattern, a wide variety of lighting can be performed by independent control. However, the lighting pattern has different preferences depending on the individual as with the design of the mobile phone. Here, there are the following setting methods (1) to (2) in order to cope with various preferences of the user.
(1) Several kinds of lighting patterns that are determined to be optimal for a mobile device by pre-installation by a manufacturer designer are prepared, and the user selects and sets them.
(2) An environment in which a user can create a lighting pattern is prepared (for example, a key illumination creation tool is downloaded to a PC), and a lighting pattern with a unique user can be set.
As an environment for creating a lighting pattern, an environment for preparing an application layer of a mobile phone and an environment for creating using a key illumination creation tool software on a PC are prepared. As described with reference to FIG. 3, the key illumination content 306 is created on the PC 303, and the key illumination content 306 is downloaded to the mobile phone 1 via the communication line. As another example, the key illumination content 306 can be stored in the mobile phone 1 using the recording medium 306.

(3) Disclose the created lighting pattern data on the Internet, and provide an environment that can be downloaded and used by anyone other than the creator.
It has the following features as additional functions. In order to secure the function as a key backlight, if the key is pressed while the illumination is lit, the illumination is stopped and the key printing (button numbers and symbols) is switched to an easy-to-see lighting. As an example, the brightness of the light 202 may be a small lamp, and the color of each light 202 may be a unified color on the entire surface. About the color at the time of lighting by the whole surface unified color, the lighting pattern can be set so that it can be lighted by various colors by mixing (mixing color) of R, G, and B colors. This is a measure that takes into account the fact that the key part blinks violently during key illumination, making it difficult to see the key printout. When it is determined that the user presses the key and performs the key operation, the illumination lighting is stopped even if the illumination is lit.
As described above, in the above-described embodiment, the key backlight 104 is used as key illumination so that the user can be entertained, and the backlight function for illuminating the key print in the dark place is provided.

Next, an example of a scene where key illumination is performed will be described.
In the case of a slide type mobile phone, the key illumination lighting linked to opening / closing of the mobile phone 1 is performed in conjunction with the key portion appearing (open state). In addition, even in the case of a mobile phone having a special shape, when the key portion is expanded to appear outside, key illumination lighting is performed in conjunction with the key portion.
As an implementation method other than the RGB light, a method of independently controlling a single color light and realizing illumination may also be executed. In this case, the color development effect is not as great as when the RGB lights are independently controlled. However, since the number of lights can be increased, it is possible to realize illumination with rich expressive power. In addition, since the monochromatic light is less expensive than the RGB light, it is possible to use a large number of lights employed for the key backlight. In this case, it is possible to express pictures (icons), numbers, and characters precisely by combining turning on and off of these lights.

It is also possible to light the key illumination during various communications of the mobile phone 1. In this embodiment, the key illumination is turned on during infrared data transmission / reception, mail transmission / reception, voice call transmission / reception, data downloading from the network, communication with the IC chip, and each communication is completed. It is also possible to turn on an illumination to notify the completion of communication at the time. One example will be described below.
(1) Key illumination during mail transmission After the user creates a mail, the key illumination lights up when the user presses the send button. When the email transmission is complete, the illumination lights up vividly to inform you that the transmission is complete. Here, since the key part appears (open state) at the time of mail transmission, the key illumination lighting is effective because it is noticed by the user.
(2) Key illumination during infrared communication Key illumination is turned on while exchanging phone book data between two mobile phones and during transmission / reception of each content (still image, video, melody, etc.). The key illumination on the transmission side is a lighting pattern indicating the state of transmission. An example of this lighting is shown in FIG. A light representing an arrow 401 is turned on from the lower part of the key (near the numeral 0 key) to the upper part of the key. That is, one of the key illuminations is turned on to indicate the shape of the arrow, and the arrow is turned on and displayed so that the arrow moves (moves) toward the mobile phone side on the receiving side every time a certain time elapses. .
In addition, there is a pattern in which a plurality of arrows are lit by gradation expression. The lighting of the arrow represents a shape by selecting a light to be lit from among the arranged lights. Since several frames blink per second, it is possible to change the lighting position.
When the transmission is complete, the illumination lights up vividly to inform you that the communication is complete. Similarly, the receiving side mobile phone has a lighting pattern indicating a receiving state. The key illumination is used as a method for the user to express his / her own identity with the aim of appealing his / her key illumination to the communication partner when exchanging data between users.

(3) Key illumination is turned on when the power of the mobile phone is turned on. When the power of the mobile phone 1 is turned on, the key illumination is turned on in conjunction with this. When the mobile phone 1 is turned on, a wake-up message is displayed on the main display to indicate that the power is turned on. Here, the key illumination lights up in conjunction with the message display on the main display. Key illumination shines with a moving lighting pattern and is used as a production effect when the power is turned on. Similarly, the key illumination is turned on when the power is turned off.

  Further, the program for realizing the function of the cellular phone 1 in FIG. 1 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into the computer system and executed, whereby the illumination is turned on. Control may be performed. Here, the “computer system” includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention.
