Keypad device of mobile communication terminal {Apparatus for Key-pad of Mobile Communication Terminal}
[7] The present invention relates to a keypad device of a mobile communication terminal capable of expressing numbers, Korean, English, special symbols, etc. using an electronic display.
[8] In recent years, mobile communication terminals have been gradually developed into portable information devices by adding various additional functions to simple phone functions, and inputting functions such as short message service (SMS), telephone number, scheduling, memo, or other information are basically performed. Not only is it equipped, it is now possible to chat and surf the web.
[9] Most of the additional functions are performed by inputting a character, and are configured to input a character by using a keypad attached to the terminal.
[10] Therefore, in addition to improving the call quality, the terminal manufacturer has also become an important part of research to increase the user's convenience by easily inputting characters.
[11] 1 is an exemplary configuration diagram showing a keypad device of a conventional mobile communication terminal.
[12] As shown in FIG. 1, a keypad device of a conventional mobile communication terminal has a typical consonant, a vowel, an English alphabet (not shown), and a number assigned to an arbitrary key.
[13] Therefore, since the symbols such as Korean, English, or special symbols must be divided and distributed according to the limited number of keys of the mobile communication terminal, the display letters written on the keys become very small, which leads to a situation that is difficult to discern, and uses other auxiliary keys. There was a problem in that the key operation is complicated.
[14] In addition, simple input devices for electronic and electronic devices, which are becoming more complicated, have limitations in expressing all the functions of the devices.
[15] The present invention has been proposed to solve the above problems, and overcomes limitations of the keypad input expression portion by using the electronic display element of the keyboard input unit of the mobile communication terminal and allows the user to clearly display the key function. It is an object of the present invention to provide a keypad device of a mobile communication terminal.
[1] 1 is a configuration example showing a keypad device of a conventional mobile communication terminal.
[2] 2 is a diagram illustrating an embodiment of a keypad device according to the present invention;
[3] * Explanation of symbols for the main parts of the drawings
[4] 200: Normal keypad display screen 201: Numeric mode
[5] 202: character mode 203: special symbol mode
[6] 204: another language mode
[16] An apparatus of the present invention for achieving the above object includes an electronic display key for variously expressing a desired character / symbol, a mode switching key for switching the display mode of the electronic display key, by pressing the mode switching key The keypad device of the mobile communication terminal is characterized in that the selection of the mode to receive a character / symbol displayed on the electronic display.
[17] The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[18] 2 is a diagram illustrating an embodiment of a keypad device according to the present invention.
[19] In the drawing, "200" is a normal keypad display screen, "201" is a numeric display in numeric mode conversion, "202" is a character display in character mode conversion, "203" is a special symbol in special symbol mode conversion, and "204" is different. When using a language, each of the different languages is displayed.
[20] The keypad device according to the present invention first mounts an electronic display. That is, a key input device is constructed by mounting an electronic display such as an LCD flat panel display on the pushbutton switch. When a key having a specially assigned mode switching function is pressed, the numeric display 201, the character display 202, the special symbol 203, and the other language 204 are easily displayed one by one.
[21] As described above, the keypad device according to the present invention will be described in more detail as follows.
[22] In the keypad device according to the present invention, each key has an electronic display. Therefore, it has the advantage that the desired characters or symbols can be variously expressed by the software.
[23] Accordingly, in order to express a character or a symbol, a desired mode 201 to 204 is selected by pressing a mode switch key specially assigned for mode switching in the standby state 200 to select a character or symbol displayed on the electronic display. To complete the message.
[24] On the other hand, the keypad device according to the present invention has the advantage that can be used while watching the language of other countries, such as Japanese, French, German, etc., because each key is an electronic display.
[25] On the other hand, the present invention as described above can be used not only in the mobile communication terminal, but also in all the electronic, electrical devices using the keypad.
[26] The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.
[27] The present invention as described above, the key definition and expression of the mobile communication terminal can be made clear, special symbols and the like can be easily displayed on the keypad, and there is an effect that can easily express a language used in various countries in particular.
