Recently, as the mobile mobile communication technology is developed, a portable input device such as a camera phone, a PDA phone, etc., has a key input unit having a 3x4 matrix to input Korean characters or English characters as shown in FIG. 2 (·), 3 (ㅡ), 4 (ㄱ, ㅋ), 5 (ㄴ, ㄹ), 6 (ㄷ, ㅌ), 7 (ㅂ, ㅍ), 8 (ㅅ, ㅎ), 9 (ㅈ, ㅊ ), Click the number once or twice to input consonants (first, last), and input Korean characters including vowels (jong) by applying 1 (l), 2 (·), 3 (ㅡ). Then, the control unit of the mobile communication terminal processes the input key value, and outputs the Hangul characters combining consonants and vowels according to a preset Hangul font size on the LCD display of the portable terminal.

In addition, the Korean input method in the portable mobile communication terminal used a consonant-only key (*), a vowel-only conversion key (#), and a pair of consonants.

In addition to the consonant input by the key input unit of the portable mobile communication terminal, vowels are combined using 'l' (1), '·' (2), and 'ㅡ' (3) when entering a collection of Korean characters. That is, the combination of 'l' and '·' into 'ㅏ' is input, and the combination of 'l' and '·' and '·' is combined into 'ㅑ' and '·' And 'l' are combined to form 'ㅓ', and '·' and '·' and 'l' are combined to 'ㅕ', and '·' and '-' are combined. It is formed as 'ㅗ' as the normal input, 'ㅛ' as the continuous input of '·', '·' and 'ㅡ', and 'TT' as the continuous input of 'ㅡ' and '·'. And vowels are formed by successive inputs of 'ㅡ', '·' and '·', combined with consonants, double consonants and vowels of primary, neutral, and final Hangul characters are input from the terminal.

It supports the Korean / English conversion key and the case-sensitive key of the alphabet that are preset in the key input unit of the portable mobile communication terminal, and unlike English, the ITU for the reduced English keyboard arrangement used for the mobile communication terminal, etc. Standardized in accordance with the recommendations of the International Telecommunication Union.

Therefore, the Korean alphabet character combining consonants and vowels according to the preset Korean font size is recognized by expressing initial, neutral, and finality by the key input unit according to the Hangul characters consisting of consonants and vowels. If you press the key button according to the number and English letter input mode, the letters and letters will be recognized by distinguishing between upper and lower case letters.

However, the key input unit of the existing portable mobile communication terminal inputs consonants displayed on the numbers 0-9 and combines the direction keys by clicking once or twice based on the direction keys, 'ㅡ', and 'ㅣ' when inputting the vowels. It was inconvenient to do it, and there was a disadvantage that the Korean input function including consonants and vowels is not provided in a touch-sensitive manner by using both a touch sensor and a 3x4 matrix keyboard.

The present invention has been proposed to solve the problems of the prior art, and an object of the present invention is to provide a Hangul input function including consonants and vowels in a touch-sensitive manner by using both a touch sensor and a 3x4 matrix keyboard in a portable mobile communication terminal. It is to provide a Hangul input device using a 3x4 matrix touch sensor keyboard.

A vowel is input (step S30), a consonant composed of a consonant, a neutral, and a final consonant is input, and a specific input key (* or #) is selected to input the Hangul character (step 40). The inputted Hangul characters are recognized by the touch sensing program and the Hangul characters are displayed on the LCD screen (step S50).

In addition, by using a touch sensor and a 3x4 matrix keyboard, all 12 buttons of 0-9, *, and # are used to sense consonants (first, last) and vowel (neutral) in a touch sense manner. In combination, a Hangul character is generated, one character is input by a specific input key (eg, *, or #), and one character is deleted by a specific delete key (eg, * or #) to reduce an input error.

Instead of the touch-type key input of the conventional mobile phone, the touch sensor is used to replace the existing consonants / vowels with the consonants / vowels instead of character matching. Match

In Korean / English character input conversion mode (* or #), select Korean character input, and use 3x4 matrix touch sensor to generate initial consonant, neutral vowel, and final consonant by touch-sensitive. Enter Korean.
