The mobile communication terminal 100 may further include devices such as a speaker for sound output, a microphone for voice input, a camera, and the like as well as the above configurations.

As described above, the touch screen unit 10 includes a display unit 110 and a touch panel 120 installed on the display unit 110. The touch panel 120 outputs a touch signal according to a user contact to the controller 12. The controller 12 may analyze the key signal from the touch screen unit 10 and calculate position data according to the contact position.

The controller 12 analyzes the key signal output from the touch screen unit 10 to determine whether the touch signal or the drag signal. When the touch signal is input, the controller 12 may display a character corresponding to the touch signal on the display unit 110 of the touch screen unit 10.

FIG. 3A illustrates an arrangement of a Korean syllable unit keypad displayed on the touch panel 120 according to a preferred embodiment of the present invention, and FIG. 3B is an enlarged view of a 'a' related keypad cell shown in FIG. 3A.

Referring to FIG. 3A, the Hangul syllable unit keypad 300 displayed on the touch panel 120 includes nine Hangul consonants 'ㄱ', 'ㄴ', 'ㄷ', 'ㄹ', 'ㅁ', 'ㅂ', It includes keypad cells respectively corresponding to 'ㅅ', 'ㅇ', and 'ㅈ'. The twelve keypad cells provided in the Hangul syllable unit keypad 300 are arranged in three horizontal columns and three vertical columns, but may be variously changed according to the size and shape of the touch panel 120.

As shown in FIG. 3B, each keypad cell includes a consonant key region 321, vowel key regions 322-331, and a function key region 332. The consonant key region 321 is assigned the corresponding consonant of the keypad cell, and the vowel key regions 322-331 are the lower sons '·', 'ㅣ', 'ㅡ', 'ㅘ', 'ㅙ' ',' ㅝ 'and' ㅞ 'are assigned respectively. The function key area 332 is located at the center of the vowel key areas 328-331 corresponding to the vowels 'ㅘ', 'ㅙ', 'ㅝ' and 'ㅞ'. The arrangement of the consonant key area 321, the vowel key areas 322-331, and the function key area 332 in the keypad cell may be variously changed.

In general, a character input using a touch screen provided in an electronic device includes a method in which a user touches or drags a finger or a tool such as a stylus pen. The input using the pen is that the area where the pen and the touch screen are touched is smaller than that of the finger, enabling delicate touch. When the width * length of the key areas in the keypad 300 is 4mm * 4mm or more, character input using a pen is possible. If the user uses a pen, the Korean characters may be input more accurately by touching the key areas 321 to 331 of the keypad 300 of the present invention. If the area of the touch screen unit 10 of the mobile communication terminal 100 shown in FIG. 1 is sufficiently wide so that the width * length of the key areas in the keypad 300 is 7mm * 7mm or more, character input using a user's finger may be performed. It is possible.

Hangeul is a language that has a writing and writing structure that forms letters of one syllable by consonants of elementary, neutral, and Jongsung. In general, in order to input Hangul into the digital information processing apparatus, it is necessary to sequentially input initial, neutral, and final characters. Letters consisting only of primary and neutral letters require two keystrokes, and letters consisting of primary, neutral, and final letters require three keystrokes. The Hangul input method using the syllable unit keypad 300 of the present invention minimizes the number of key inputs, which will be described below.

Hangul's choson becomes one of 19 consonants. The first consonants are divided into general consonants and double consonants.

General consonants A, b, c, d, k, k, k, k, k, k, k, k, A double consonant ㄲ, ㄸ, ㅃ, ㅆ, ㅉ

First, the case where the first consonant is a general consonant and a single syllable composed of the first and the neutral is described.

The initial and neutral are input by the user touching any one of the vowel regions 322-331 of the keypad cell using a finger or a stylus pen. For example, when a user wants to enter a value, the user touches a collection key area 324 of a collection '·' in a keypad cell associated with the letter 'a'. The controller 12 considers that 'ga' is input when the vowel key region 324 is touched below, and controls the display unit 110 to display ga. That is, by touching the vowel key region 324 below, the 'ga' combined with the initial and the neutral may be input. In the same way, when the user wants to input the ruler, the ruler coupled to the initial and the neutral can be input by touching the 'ㅙ' vowel key region 329 of the keypad cell associated with the 'a' once. The lower '·' vowel key region 322 located on the left side of the vowel 'ㅣ' is an area for inputting the vowel 'ㅓ', and the lower '·' vowel key region 324 located on the right side of the vowel 'ㅣ' is a vowel Key to input 'ㅏ'. In addition, the bottom '·' vowel key area 325 located above the vowel 'ㅡ' is a key for inputting the vowel 'ㅗ', and the bottom '·' vowel key area 327 located below the vowel 'ㅡ' Key to enter the vowel 'TT'.

As described above, the initial consonant of the initial is automatically input by touching the vowel area, so that a touch for inputting the general consonant is unnecessary. However, drag input is required to input double consonants.

That is, the controller 12 considers that the consonant is input when the drag signal is input using the basic consonant area as a starting point. For example, if a user wants to input ㄲ ', the user touches a point in the consonant region' ′ 321 and drags it to the right while maintaining the touch state. Dragging to the right direction is for giving the same direction as the direction in which the consonants are arranged, and can be set to drag in the vertical direction by appointment. In this case, the starting point of the drag should be within the basic consonant area, but the end point may be outside the basic consonant area.

If the consonant is a double consonant, the consonant is input by the drag input as described above, and the vowel that is the neutral must be separately input. For example, in order to input "co", drag for input of "ㄲ" and touch of the lower "*" vowel key area 325 for input of "ㅗ" are required.

Neutral is divided into short vowels and double vowels. Table 2 summarizes the single vowels and double vowels that can be input by one touch and the double vowels that can be input by two touches.

Vowel classification Touch drag collection monophthong One x ㅏ, ㅓ, ㅣ, ㅗ, ㅡ, ㅜ monophthong 2 x ㅑ, ㅕ, ㅛ, ㅠ Double Vowels One x ㅘ, ㅙ, ㅝ, ㅞ Double Vowels One o ㅔ, ㅐ, ㅚ, ㅢ, ㅟ Double Vowels 2 o  ㅖ, ㅒ

In Table 2, when the vowels that can be input by one touch are shown together with the keypad cells shown in FIG. 3B, 'ㅏ' is a vowel key region 324, 'ㅓ' is a vowel key region 322, and 'ㅣ' is a vowel. Key area 323, 'ㅗ' is a collection key area 325, '-' is a collection key area 326, 'TT' is a collection key area 327, 'ㅘ' is a collection key area 328, 'ㅙ' is input by a touch of the vowel key area 329, 'ㅝ' is a vowel key area 330, and 'ㅞ' is a touch of the vowel key area 331.

Short vowels 'ㅑ', 'ㅕ', 'ㅛ', and 'ㅠ' are assigned to vowel key regions 322, 324, 325, and 327 assigned to the lower subkey, respectively, and the control unit 12 selects the vowel key. When the regions 322, 324, 325, and 327 are touched twice in succession, the vowels 'ㅑ', 'ㅕ', 'ㅛ', and 'ㅠ' are recognized as input.

Double vowels 'ㅘ', 'ㅙ', 'ㅝ' and 'ㅞ' are assigned to vowel key regions 328-331, respectively. Therefore, the double vowels '영역', 'ㅙ', 'ㅝ', and 'ㅞ' can be input to the digital information processing apparatus 100 by touching the vowel key areas 328-331 once.

The short vowels 'ㅐ', 'ㅔ', 'ㅚ' and 'ㅟ' are combined with 'ㅓ', 'ㅓ', 'ㅗ', 'TT' and 'ㅣ' respectively. Short vowels 'ㅐ', 'ㅔ', 'ㅚ', and 'ㅟ' are assigned to vowel key regions 322, 324, 325, and 327 assigned to the lower subkey, and control unit 12 collects the vowel keys. When the regions 322, 324, 325, and 327 are touched and dragged in a predetermined direction in the touched vowel key region, the vowels 'ㅐ', 'ㅔ', 'ㅚ', and 'ㅟ' are recognized as input. . The drag direction is downward in the vowel key area to match the direction of the vowel. However, the drag direction can be changed in various ways. Also, the starting point of the drag should be in the vowel key area, but the end point may be outside the vowel key area.

The controller 12 recognizes that a double vowel 'ㅢ' is input when '-' of the vowel key region 326 is touched and dragged downward in the vowel-key region 326 '-'.

The double vowel 'ㅖ' is a combination of the short vowel 'ㅕ' and the short vowel 'ㅣ'. Therefore, the double vowel “ㅖ” is formed by touching the vowel key region 324 for inputting the short vowel 'ㅕ' two times in succession and then dragging downward from the vowel key region 324 to enter the 'ㅣ'. Can be entered.

Similarly, the double vowel 'ㅒ' is the combination of the short vowel "ㅑ" and the short vowel "ㅣ". Therefore, the double vowel “ㅒ” is formed by touching the vowel key area 322 for inputting the short vowel 'ㅑ' two times in succession and then dragging downward from the vowel key area 322 to enter the 'ㅣ'. Can be entered.

Table 3 shows the double vowels separated into two short vowels.

Double Vowels Short vowel separation ㅔ ㅓ + l ㅖ ㅕ + l A ㅏ + l ㅒ ㅑ + l ㅚ ㅗ + l ㅢ ㅡ + l ㅟ  TT + l

To sum up, the remaining double vowels except for the vowels 'ㅘ', 'ㅙ', 'ㅝ', and 'ㅞ' assigned to the vowel key areas 328-331 may touch the corresponding vowel key area twice. Or by touching and dragging the corresponding short vowels.

Other methods for entering double vowels 'ㅔ', 'ㅐ', 'ㅚ', 'ㅡ' and 'ㅟ' include the lower '·' vowel key areas (322, 324, 235, 237) and the 'ㅡ' vowel. Without touching the key area 326, there is a downward drag in the '*' collection key areas 322, 324, 235 and 237 and the '-' collection key area 326.

In other words, when dragging downward in the '*' vowel key region 322 downwards, ',' is input, and dragging downward in the downward '·' vowel key region 324 is inputted 'ㅐ', and downward ' '' Is dragged downward in the vowel key area 325, 'ㅚ' is input, and 'ㅟ' is dragged downward in the vowel key area 327, and 'ㅡ' is pressed. In the area 326, when dragging downwards, 'ㅢ' is input.

On the other hand, another method for inputting the vowels 'ㅖ' and 'ㅒ' is to drag in the lower right direction in each of the lower '·' vowel key regions 322 and 324. That is, when dragging in the lower right '·' vowel key area 322 in the lower right direction, 'ㅖ' is input, and when dragging in the lower right '·' vowel key area 324 in the lower right direction, 'ㅒ' is input. In this way, all short vowels and double vowels can be input to the digital information processing apparatus.

There are two ways to enter the finality. First, the consonants corresponding to the final consonants in the consonant key regions are touched. Table 4 shows the consonants that are frequently used as the final consonants and the consonants that are not often used as the finalities.

Consonants often used as a finality A, b, d, ㅁ, ㅂ, ㅇ Consonants not often used as a finality ㅡ, ㅎ, ㅎ, ㅋ, ㅋ, ㅎ, ㅆ,
ㄲ, ㄳ, ㄵ, ㄶ, ㄽ, ㄾ, ㅄ, ㄱㄱ, ㄹㅁ, ㄹㄷ

For example, if the user wants to input 'b' as the finality, the finality 'a' is input by touching the consonant key region 321 once. In addition, in order to input 'ㄲ', the consonant key region 321 corresponding to 'a' is touched twice.

Another way to enter a finality is to write the consonants 'a', 'b', 'ㄹ', 'ㅁ', 'ㅂ' and 'ㅇ' which are frequently used as a finality. The method of handwriting inputting the finality is possible by inputting a preset short stroke on the vowel key areas 328-331. The vowel key areas 328-331 are areas for inputting vowels 'ㅘ', 'ㅙ', 'ㅝ', and ','. Since the vowels are input only by the touch signal, the drag signal is not received. Inputting a short stroke corresponding to consonants for the final input by dragging does not cause crosstalk in the signal.

Table 5 below shows the consonants that are frequently used as finalities and their corresponding short cuts.

Jongseong Shorthand Characteristic A │ Last stroke of 'ㄱ' N ― Last stroke of 'ㄴ' D 〓 Vertical stroke of 'ㄹ' ㅂ ∥ Left and right position stroke of 'ㅂ' M // 2 diagonal strokes ㅇ Of 1 diagonal stroke

The control unit 12 shown in FIG. 2 illustrates an arrangement of the keypad 300 shown in FIG. 3A so that the finality can be input when the vowel is input through the touch panel 120 shown in FIG. 3A. Change it together.

4A to 4C are diagrams illustrating changes of a keypad displayed on a touch panel when a neutral vowel is input in a mobile communication terminal of the present invention.

In the state in which the keypad 300 as shown in FIG. 3A is displayed on the touch panel 120, any one of the vowel key regions of the first row corresponding to the consonants 'a', 'b', and 'c' is touch / drag. As shown in FIG. 4A, the controller 12 changes the vowel key areas of the first row into consonant key areas for the final input and displays them on the touch panel 120.

When the final consonant is displayed in the first row of the keypad 400, the final consonant is also displayed in the function key areas. The vowel key areas of the keypad cell associated with the consonant 'a' are displayed with 'a', 'b', 'r' and 'o', respectively, and 'ㅁ' and 'ㅂ' are displayed in the function key area. The vowel key areas of the keypad cell associated with the consonant 'b' are displayed with 'ㅋ', 'ㄷ', 'ㅈ' and 'ㅊ' respectively, and the function key area is marked with 'ㄲ'. In the vowel key areas of the keypad cell associated with the consonant 'c', 's', 'ㅎ', 'c' and 'ㅌ' are respectively displayed, and 'k' is displayed in the function key area.

기능키가 사용된다. 예를 들어, '가가'를 입력하기 위해서 아래아 '·' 모음키 영역이 연속 2회 터치되면, '갸'가 입력된다. 그러므로 'ㅏ'에 대응하는 아래아 '·' 모음키 영역을 1회 터치한 후

기능키를 터치하고 나서 다시 아래아 '·' 모음키 영역을 1회 터치하면 '가가'가 입력될 수 있다.Previously mentioned in Table 6

The function key is a reset key. In a state where a keypad as shown in FIGS. 4A to 4C is displayed on the touch panel 120

When the function key is touched, the controller 12 displays the keypad 300 as shown in FIG. 3A. Also, to input the same Hangul combined with 'consonant consonant + neutral vowel' consecutively

Function keys are used. For example, in order to input 'Ga-ga', when the lower '·' vowel key area is touched twice in a row, 'Ga' is input. Therefore, after touching the bottom '·' vowel key area corresponding to 'ㅏ' once

If the function key is touched again and then touches the '.' Vowel key area once, 'Gaga' may be input.

기능키가 사용된다. 예를 들어, '가과'를 입력하고자 하는 경우, '가'를 입력하면 도 4a에 도시된 바와 같이 첫 번째 행의 모음키 영역들에 종성 자음이 표시되므로 '과'를 입력할 수 없다. 그러므로 '가'를 입력후

기능키를 터치하여 도 3a에 도시된 키패드(300)를 표시한 후 '과'를 입력할 수 있다.As another example, when entering Hangul consonants 'ㅘ', 'ㅙ', 'ㅝ' and 'ㅞ' after inputting Korean combined with 'consonant consonant + neutral vowel'

Function keys are used. For example, if the user wants to input 'Ka', 'Ka' cannot be input because the final consonant is displayed in the vowel key areas of the first row as shown in FIG. 4A. Therefore, after entering 'A'
