Description

Input and Display Apparatus of Character or Number and Communication Terminal Apparatus using kind}

The present invention relates to an input display device and a data input method for inputting and displaying data in a communication terminal, and more particularly, to an apparatus for inputting and displaying letters or numbers and a communication terminal using the same.

Due to the rapid development of wireless communication systems, communication terminals such as portable telephones generally perform functions of transmitting and receiving data communication and short messages as well as ordinary voice calls. In particular, the short message service is a function for transmitting and receiving relatively short sentences that can be used in daily life between users is increasingly being used.

In order to support such a function, a communication terminal includes a keypad capable of inputting a character, and according to a trend of miniaturization of electronic devices, most communication terminals input characters using a number key for dialing.

As a prior art for inputting Hangul in a wireless communication terminal, there is one disclosed in Korean Laid-Open Patent Publication No. 1996-042304.

This is a so-called 'heaven' method, which relates to an apparatus and method for generating consonant and vowel codes for Korean input, having only horizontal and vertical stroke keys and a plurality of numeric keys assigned with a plurality of at least two consonants. will be.

1 is a plan view illustrating a Hangul input device disclosed in Korean Laid-Open Patent Publication No. 1996-042304.

As shown in Fig. 1, the digits 9 and 0 located on the keypad are assigned a stroke key →, ↓ for inputting a vowel, respectively, and the 8 key is a stroke key for determining the length of the stroke. Is assigned. A plurality of consonants in Korean are assigned to keys 1 to 7, and a plurality of consonants are assigned to one key. The keypad is attached to the lower portion of the LCD, and the user can input desired data by pressing numeric or character keys respectively assigned to the keypad.

The character input method of the Cheonjiin method shown in FIG. 1 has an advantage of allowing Korean characters to be input with a minimum of keys in that all vowels of Korean characters can be represented by a combination of three stroke keys. However, since all vowels except for 'ㅡ' and 'ㅣ' are composed of a combination of strokes, there is a problem in that the number of strokes for pressing a key increases in inputting characters. In particular, `` cold '' and `` cold '' folds require you to press the stroke key more than 5 times, which complicates character input and takes a long time to enter a single character.

As another related art related to a character input method and apparatus, there is one disclosed in Korean Unexamined Patent Publication No. 2000-0049346.

This is a so-called 'naratgle' method, and relates to a Hangul input method and apparatus based on the principle of Hunminjeongeum disciple.

2 is a plan view illustrating a Hangul input device disclosed in Korean Patent Laid-Open Publication No. 2000-0049346.

The Hangul input device illustrated in FIG. 2 sets 'a, b, ㅁ, ㅅ, ㅇ, ㄹ, ㅡ, ㅣ, ㅏ, ㅓ, ㅗ, TT' as basic consonants and basic vowels according to the principle of Hunminjeongeum disciples, and By providing a key and a parallel key, all phonemes of the Hangul can be input. That is, the stroke key shown in FIG. 2 is used to add one stroke to the basic consonant and the basic vowel, and the parallel key is used to input the horn. For example, to enter 'ㄷ', press the capture key in 'b', and to enter 'ㄲ', press the parallel key in 'ㄱ'.

However, in the character input method according to the principle of the Hunmin Jeongeum disciple shown in FIG. 2, 'ㅏ, ㅓ', 'ㅗ, TT' keys are allotted to the same numeric key, and two capture keys and parallel key keys are arranged. There is a disadvantage that more than 50% of characters can be completed only by using the catch and disease keys.

In addition, there is a so-called 'Sky' type Hangul input device disclosed in the Republic of Korea Patent Publication No. 2002-0039482. This method selects both terminal sounds and short vowels as basic phonemes, and assigns two basic phonemes to each numeric key, so that characters can be input more quickly than the narrative method. However, this causes a problem in entering the double vowel 'ㅢ' because the vowels 'ㅡ' and 'ㅣ' are assigned to one numeric key.

As described above, most conventional technologies for the Hangul input device are based on the 12-key method for existing dialing according to the trend of miniaturization of communication terminals. That is, in order to input both Korean and English characters to the 12 keys, there is a problem in that a plurality of characters must be represented by one numeric key or a combination of numeric keys.

In addition, wireless communication terminals generally tend to be miniaturized, whereas screen displays have become larger. In order to meet the demand for miniaturization of a communication terminal and enlargement of a screen display unit, a folding type has been developed to allow folding between a screen display unit and a keypad disposed at the bottom of the screen display unit. However, this clamshell had a problem that the screen was not seen from the outside.

The improvement is a dual folder type which separately installs a display device outside the folder so that necessary information can be viewed outside the folder, and currently occupies most of the mobile phone market. However, this dual folder type caused an increase in the cost and weight of the terminal according to an external display window, and it was inconvenient to open a folder window to input data.

As an improvement of the above-mentioned problem of the folding type, there is a sliding type that is distributed in the market these days. This is a method of sliding down the keypad portion at the bottom when making a call or entering data, and raising it at other times. However, this is also a hassle to bring down the keypad every time you make a call.

The present invention is to achieve a lighter weight and a smaller size of the communication terminal by saving space of a keypad for inputting letters or numbers of the communication terminal.

Another object of the present invention is to reduce the manufacturing cost of a communication terminal by replacing the dual folder type with a bar.

It is yet another object of the present invention to increase the number of keys for inputting characters and to arrange them appropriately so that the characters can be entered conveniently and quickly.

Still another object of the present invention is to provide excellent performance in inputting Hangul using both hands.
