In addition, the present invention relates to a Korean and English input method and apparatus having a scroll function using a touch sensor array used in a multifunctional information input device.

In general, Hangul is based on the unification of Korean spelling, the consonants a, b, c, d, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k, k , Neutral 성, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ,, ㅠ, ㅡ, ㅣ, ㅐ, ㅒ, ㅚ, ㅟ, ㅘ, ㅝ, ㅙ, ㅞ, finality a, b, c, d, ㅁ, ㅂ , ㅅ, ㅇ, ㅈ, ㅁ, ㅋ, ㅌ, ㅅ, ㅎ, ㄲ, ㅉ, ㅅㅅ, ㄴㅈ, ㅎㅎ, ㄹㄱ, ㄹㅁ, ㄹㅂ, ㄹㅅ, ㄹㅌ, ㄹㅍ, ㄹ, ㅁㅅ, ㅂㅅ.

In addition, the number of letters that can be theoretically formed by combining initial, neutral, and final is 11,172 (19x21x28) characters. However, the actual number of Hangul characters that are commonly used is about 2,500 characters, and in the case of a commonly used completed code or combined code, 1,800 to 1,900 characters can be represented.

As shown in FIG. 1, when a user inputs a number or Korean through a key input unit of a mobile communication terminal, the input key value is inputted to a mobile communication terminal such as a smart phone, a PDA phone, a camera phone, a PDA, and the like. The CPU processes the input number and displays it on the LCD screen of the terminal. The inputted Hangul is searched for the input key value using the Hangul font embedded in the Hangul font memory. It is displayed on the LCD screen of the terminal.

Recently, the Korean input method in a portable mobile communication terminal uses a consonant-only key (*), a vowel-only conversion key (#), and a key for twin consonants separately.

In addition to consonant input by a key input unit of a portable mobile communication terminal, vowels are combined using 'l', '·', and '-' when the vowel is input. 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. Combination of 'ㅗ' as the normal input, 'ㅛ' as the continuous input of '·', '·' and 'ㅡ', 'TT' as the continuous input of 'ㅡ' and '·' And vowels are formed by successive inputs of 'ㅡ', '·' and '·', and consonants, double consonants, and vowels of the primary and neutral species are combined to input Korean characters.
