Description

A keypad of character input for mobile phone}

The present invention relates to a character input keypad of a mobile terminal. More specifically, all Korean consonants, vowels, and English characters are placed on the input button of the mobile terminal, and all consonants and vowels are consistently combined using an input button, and sequentially. The present invention relates to a keypad capable of entering Korean and English characters easily and quickly.

The mobile communication system sends a call message containing the unique number of the mobile terminal called through the call channel of the base station to call the mobile terminal, and when a response is received from the specified mobile terminal, a call is established between the sender and the receiver. It is a system that makes it possible.

In addition, such a mobile phone terminal has been able to communicate data as the digital method is adopted, it is possible to provide a variety of services such as text services by using such data communication.

In order to input characters required for such data communication, the mobile phone terminal is provided with characters that are assigned to each keypad in addition to numbers to keypads for inputting numbers, as in conventional telephones. Special characters, etc., the user can express almost anything you want.

A conventional character input method will be described with an example using the keypad shown in FIG. 1.

In order to input an English letter, the keypad includes two or three corresponding buttons of each numeric button and an English alphabet corresponding thereto.

That is, QZ is set to 1, ABC is set to 3, DEF is set to 4, GHI is set to 5, JKL is set to 6, MNO is set to 6, PRS is set to 7, TUV is set to 8, and WXY is set to 9.

In the conventional character input method using a keypad in which English letters are written together, the numbers are inputted by dialing the buttons in which the corresponding numbers are written in the same way as the number input button of a telephone when a number is first inputted. .

In case of inputting letters, the function assigned to the button is displayed by pressing the same number button several times in succession after switching from call mode to text input mode by operating a separate function button. Depending on whether you have operated the number of times, the English characters written on the corresponding button are sequentially changed and input.

For example, pressing the number button [3] once will display the first letter, D, on the LCD display, pressing [3] two times in succession, E three times in succession, and F will appear. When pressed consecutively, 3 is displayed.

That is, if you keep pressing [3], D, E, F, 3, D, E…. Appears sequentially on the liquid crystal display, and if desired characters appear, allow a certain time to elapse, allowing the current character to be input to the mobile phone terminal, and moving the cursor on the liquid crystal display to receive the next character. Using the same method as before, you can continue typing to produce sentences.

In addition, various methods for inputting text into a mobile terminal have been proposed.

2a to 3b illustrate a conventional general character input keypad and method.

Character input of mobile phone is small and standard keyboard is limited to 12 digits of '0-9, *, #', and Hangul is not easy because consonants and vowels are combined.

First, Figure 2a is a configuration of the keyboard adopting the 'Cheonjiin' method.

As shown in FIG. 2A, a function button unit 210 for selecting various functions, number buttons 200 to 209 for numbers 0 to 9, and direction buttons without reference numerals are provided. 'Cheonjiin' method is a way to mark all the vowels with only three buttons, thousand (·), ji (ㅡ) and in (ㅣ). For example, pressing 'ㅣ' followed by '·' becomes 'ㅏ', and if you press 'ㅣ' again, it becomes 'ㅐ'. In addition, if you want to express the sound such as 'ㄲ', 'ㄸ' among the consonants, press the 'ㄱ', 'ㄷ' button three times in a row.

2b is a flow chart for inputting 'pretty' by adopting the Cheonjiin method, first by using the menu button in the character input mode, and then pressing the 0 button 200 combined with 'ㅇ' (221), 'ㅇ 'Is displayed (241), press the 2 button 202 combined with' · 'twice to make' ㅕ '(222) and press the 1 button 201 combined with' ㅣ 'here (223) ) 'F' (243), and if you press the first button 201 (224) becomes 'Yes' (244).

And pressing the 7 button 207 combined with 'ㅂ' three times (225) 'Yes' (245), pressing the three buttons (203) combined with 'ㅡ' (226) becomes 'pretty' (246), and then press the 6 button 206 combined with 'c' (227) 'pretty' (247), then press the 1 button 201 combined with 'ㅣ' again (228) 'pretty D '(248), and when the two buttons 202 combined with' · 'are pressed (229),' pretty 'is displayed (249).

Figure 3a is a block diagram of a keyboard that introduces another method 'Naratgle 2000'.

A function key unit 312 for selecting various functions, number buttons 300-309 up to 0-9, an overwrite 310 button, and side by side buttons 311 are provided.

'Naratgle 2000' is a method that applies the principle of Hunminjeongeum to support 6 consecutive consonants and 6 vowels on 9 keyboards to support continuous input of Korean characters. ) And 'Side by Side' (311) 'function keys to express all letters.

For example, pressing 'a' and 'side by side (311)' one after another 'ㄲ', 'ㅏ' followed by 'overwrite (310)' '방식' is a combination method. ㄴ 'followed by the' overwrite '(310) once, it becomes' ㄷ', and if you press' overwrite '(310) once more, it becomes' ㅌ'.

FIG. 3B is a diagram illustrating a sequence of inputting 'pretty' as in FIG. 2B. When the 6 button 306 combined with 'O' is pressed (321), 'O' is displayed (341), and 'ㅏ' ㅓ '7' is pressed twice (322) 'er' is displayed (342), then 'overwrite' button 310 is pressed (323) 'F' is displayed (343), again Pressing the 9 button 309 in combination with 'ㅣ' twice (324), 'Yes' is displayed (344).

Then, pressing the four buttons 304 combined 'ㅁ' (325) '옘' is displayed (345), then pressing the 'overwrite' button 310 (326) '옙' is displayed (346), Pressing the button 311 side by side again (327) 'Yes' is displayed (347), and pressing the 9 button 309 combined with '-' (328) 'Pretty' is displayed (348).

And pressing the 2 button 302 combined with 'b' (329) 'Pretty' is displayed, press the overwrite button 310 again (330) 'Pretty' is displayed (350), and finally 'ㅏ Pressing the 7 button 307 combined with '(331)' pretty 'is displayed (351).

However, there are many ways to use the keypad of a phone or a mobile phone as described above, but it is very difficult to select a character element because it is very cumbersome and it takes time if you do not know the dial in advance. Uncomfortable.

However, in the conventional method of inputting a character, in order for a desired character to be input, the user presses each number button to sequentially search for a number entered in one button to find a desired character. Wait as much as possible.

Therefore, this method must not only remember exactly how many times the user has pressed a number, but also wait to check and display the displayed characters when the desired characters appear on the LCD display, and to enter characters different from those desired during this process. Is a problem, and eventually a sentence different from the sentence desired by the receiver is often made.

The present invention has been made to solve the above problems, the object of which is to press a button according to the user's selection in the case of inputting a desired character from among several characters allocated in parallel to one button, The present invention provides a character input keypad of a mobile terminal that can input characters more easily and conveniently, and can prevent character input errors.

In addition, the present invention by placing all the Korean consonants, vowels, and English characters on the input button of the mobile phone and consistently combine all the consonants and vowels using the input button, you can quickly and easily enter the Hangul and English alphabets arranged alphabetically The present invention provides a character input keypad of a portable terminal.
