[10] Differently from a general micro controller unit, the micro controller unit does not control the light emitting devices by the operation of a special key of the keyboard, but controls the built-in switches operated by using the colors processed by software mounted on the computer and information on the designated keys. Therefore, the light emitting devices can respectively lighten keys with the designated color or colors.
[11] There is also provided a method of selecting colors of keys of a keyboard, the keyboard being connected to a computer as an input means, and including a plurality of keys each respectively including a symbol region on its top surface, light emitting devices each respectively disposed below a key to lighten the top surface of the key, and a micro controller unit having switches for controlling the light emitting devices, the method including: a first step for receiving a request of selecting the colors of the keys of the keyboard from an input device; a second step for displaying a screen on a monitor for key selection and color selection of the selected key; a third step for receiving information on the color-selected key from the input device; and a fourth step for transmitting the information to the micro controller unit of the keyboard.
[12] Preferably, the method further includes a fifth step for controlling, at the micro controller unit, the light emitting devices by the switches according to the transmitted information.
[13] Preferably, a mouse is mostly used as the input device. The keyboard itself can be operated as the input device. Advantageous Effects
[14] In accordance with the present invention, the user can apply wanted colors to the target keys.
[15] The user can improve operational efficiency by increasing visibility of the characters often used in the computer operation using many keys of the keyboard. Also, the user can improve operational efficiency with the customized keyboard by obtaining target color characters by light sources having three primary colors.
[16] Furthermore, the user can perform the computer operation even in a dark space.

[26]
Mode for the Invention
[27] A keyboard and a method of selecting colors of keys of the same in accordance with the present invention will now be described in detail with reference to the accompanying drawings.
[28] Fig. 2 illustrates some keys of the keyboard in accordance with the present invention. The keys include red color keys 1, blue color keys 2, green color keys 3, violet color keys 4 and orange color keys 5.
[29] Fig. 3 illustrates one example of the key of the keyboard in accordance with the present invention. A light emitting device 20 having RGB (red, green and blue) diodes is disposed below a key 10.
[30] The top surface 30 of the key 10 is formed wholly opaque and a symbol region 40 composed of a character or a mark is formed to transmit light. That is, the key 10 is made of a light transmitting material, and a coating solution 50 is opaquely coated on the top surface 30 or the whole outer surface of the key 10 and removed from the area corresponding to the symbol region 40 by laser processing. Also, the key 10 is formed by double injection so that only the symbol region 40 can transmit light. In addition, the whole key 10 or the top surface 30 of the key 10 may be formed to transmit light, with the symbol region 40 opaque. In the case that a reflecting plate 60 is formed on the inner surface of the key 10 by plating, the reflecting plate 60 can improve efficiency of light emitted to the top surface 30 of the key 10.
[31] In the right side of Fig. 3, the symbol region 40 has a blue color. Such a color can be varied by controlling the light emitted from the light emitting device 20.
[32] The method of selecting the colors of the keys of the keyboard in accordance with the present invention will now be described.
[33] Fig. 4 illustrates the method of selecting the colors of the keys on a monitor in accordance with the present invention. Color selection is carried out by displaying the keys of the keyboard on the screen, designating the color by a color designating window 71, and selecting the corresponding key 73 by a cursor 72.
[34] Fig. 5 illustrates one example of a physical structure for selecting the colors of the keys in accordance with the present invention. The operational principle of the light emitting devices 20 is similar to that of the general LEDs of Fig. 1.
[35] In general, the keyboard is controlled by a built-in control IC, namely, a micro controller unit (MCU). Basically, the MCU transmits electric signals generated by mechanical signals of the keys of the keyboard to a computer main body. Besides, the MCU turns on and off the LEDs disposed at the upper portion of the right side of the keyboard for displaying the operation of function keys such as scroll lock and caps lock .
[36] In order to designate the colors of the keys of the keyboard and emit the designated colors by the light emitting devices disposed below the keys, a driving program 81 for displaying the keys of the keyboard on the screen upon the request of the user as shown in Fig. 4, enabling the user to designate the colors of the keys, receiving the designated colors, and finally transmitting the colors to the MCU of the keyboard is mounted on a computer 80 as software. A keyboard 90 includes an MCU 91 having switches 92 for controlling the current supplied to the light emitting devices 20.
[37] The user requests a color selection mode to the computer 80 through an input device 201 such as a mouse. The computer 80 executes the driving program 81 in response to the request of the user. After color selection, the computer 80 transmits the related information to the MCU 91 of the keyboard 90. The series of processes of the computer 80 are performed by a CPU 82 of the computer 80.
[38] For example, when the user designates the specific key with the red color, the MCU
91 turns off the switches of the LEDs corresponding to the blue and green colors and turns on the switch of the LED corresponding to the red color to display the key with the red color. In addition, when the user designates the key with the violet color, the MCU 91 turns on the switches of the LEDs corresponding to the blue and red colors, thereby displaying the key with the violet color. In addition, the same color can be displayed with various spectra by controlling the amount of supplied current.
[39] Fig. 6 illustrates the series of processes performed in the driving program. Whether the color selection request is received from the user is confirmed in an initial stage. If the color selection request is received (Sl), the screen for color selection is displayed to the user (S2). The processes of selecting the keys and the colors are consecutively carried out on the screen as shown in Fig. 3 (S3). When the user notifies completion of the selection process (S4), the driving program 81 is ended.
[40] Although the preferred embodiments of the present invention have been described, it is understood that the present invention should not be limited to these preferred embodiments but various changes and modifications can be made by one skilled in the art within the spirit and scope of the present invention as hereinafter claimed.
