Description

How to control Korean code generation and display

The present invention relates to a method for displaying characters in a display device having limited font information, and more particularly, to a method for reducing the load caused by a combination of Hangul and efficiently displaying the combined Hangul.

Typically, a display unit such as a liquid crystal display has limited font information. Specifically, the LCD controller has font information of letters to be displayed. The control unit causes the corresponding font to be expressed in an N × N matrix on the liquid crystal display as the font information when a command to display a letter designated by the liquid crystal display is transmitted from an external device.

When inputting Hangul from an electronic device such as a computer, the Hangul inputted by Choseong, Neutral, and Jongsung are received in order to express Hangul that is combined at each stage. In other words, when the first consonant is input, the first consonant is displayed, and when the neutral is input, the first consonant is represented by the initial consonant. In addition, when Jong-sung is inputted, it expresses letters consisting of 'choseong + neutral + Jongseong' again.

1 is a diagram illustrating a Hangul code generation process according to a conventional embodiment. If you input 'HAN', the display device displays one location in the order of 'ㅎ' → 'DOWN' → 'HAN'. This method is used to generate the code of 'ha' using 'ㅎ' and 'ㅏ' to indicate 'ha', and to generate 'one' code using 'ha' and 'ㄴ'. It executes two Hangul code generation process.

2A and 2B illustrate a Jamo correction process according to a conventional embodiment. According to FIG. 2A, 'b' is deleted when a predetermined delete key is pressed in a state where 'han' is combined through the process of FIG. 1 (in this case, the cursor K is positioned below 'han'). If you press the erase key again, 'ㅏ' is erased. In this way, if only 'ㅎ' remains, enter '에서' and then enter 'ㄴ' to create 'heon'. The generation of Hangul code occurs every time during the whole process. That is, seven Korean codes are generated until the letter “Hun” is completed.

According to FIG. 2B, the 'han' is erased by pressing the erase key in the state in which 'han' is combined (the cursor K is located next to the 'han') through the process of FIG. 1. In this case, enter 'ㅎ', 'ㅓ', 'ㄴ' sequentially to generate 'heon'. The generation of Hangul code occurs every time during the whole process. That is, six Korean codes are generated until the letter “Hun” is completed.

As such, if the generation of Korean code occurs frequently until one character is completed or modified from the completed character, the overall system performance is reduced.

Accordingly, an object of the present invention is to provide a method for generating a Korean code and a display control method for improving the performance of an entire system by reducing a process of generating a Korean code and reducing a display operation process using a display device.

In order to achieve the above object, the present invention only displays each letter that is input when the letter is being input in order to reduce the Hangul code generation process required before completing one letter of the Hangul, and the letter is input until the letter is completed. It is characterized by generating the Hangul code for the character.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

3 is a block diagram of a Hangul code generation and display control apparatus according to an embodiment of the present invention. The display unit 100 displays characters so that the user can see them. The Hangul code memory 300 is a database that stores codes corresponding to arbitrary Hangul characters. The Jamocode memory 400 is a database that stores codes corresponding to arbitrary Korean alphabets. The input unit 200 includes a plurality of keys for inputting a letter of the Korean alphabet and a numeric key for inputting a phone number. The controller 500 accesses the Hangul code memory 300 and the Jamocode memory 400 to detect or combine the Hangul code corresponding to the character input by the user, and controls the display thereof. The display control by the control unit 500 is characterized in that when the letter is being input, each letter is displayed only, and when the letter is completed, a Hangul code for the letter is generated by using the letter.

4 is a state transition diagram showing a Hangul code generation and display control process according to an embodiment of the present invention. State S ₀ is the state waiting for input. Wherein when the input consonant transitions to state S _1. In this state, the consonants input to the display unit 100 are output. When the vowel is input in the S ₁ state, the state transitions to the S ₂ state and the vowel is output to the display unit 100. When the consonant is input again in the S ₂ state, the state transitions to the S ₃ state and the input consonant is output to the display unit 100. If "End" is input in S ₂ or S ₃ state, it branches to S ₃ state. In each state, the entered Jamo code is read from the Hangul alphabet code memory and stored. In the S ₄ state, the input of the alphabet is completed. The alphabet is stored using the input alphabet, and the completed Korean code is generated by referring to the Korean code memory. The generated code is transmitted to the display unit 100 to display the corresponding Hangul. If at S ₃ state back bar is input generating a Hangul code S ₄ state to the consonant + vowel + consonant input to bar the input consonant + up S ₂ state or S ₃ state, and collection and the consonants input on the S ₃ state Transitions to the S ₀ state to be used for generating a new character code.

5 is a diagram illustrating a Hangul code generation process according to an embodiment of the present invention.

First, a process of inputting Korean into the input unit 200 and outputting from the display unit 100 will be described below with reference to a specific example. The first consonant input through the input unit 200 is a consonant, which is displayed on the display unit 100 as it is.

(Example) enter: "ㄱ"

Show: "ㄱ"

Next, when a vowel is entered, it will display the consonants described above and then place them.

(Example) enter: "ㅏ"

Show: "ㄱ '' ㅏ"

When a consonant is input again, it is displayed at the next position of the above-mentioned consonant and vowel.

(Example) Enter: 'ㄹ'

Show: "ㄱ" "ㅏ" "ㄹ"

When consonants, vowels, and consonants are input, they can be considered to have completed one letter. In this case, when an input for inputting the end of the input is input from the input unit 200, a one-letter code is generated using the previously input 'consonant + vowel + consonant' and output to the display unit 100. However, "end" is a signal indicating completion of character input.

(Example) enter: "end"

Show: "go"

If 'consonant + vowel + consonant' is input and the consonant is input again, it is checked whether the consonant of the current input and the previous consonant can form a double consonant or a double consonant. If double consonants or double consonants are possible, these two consonants form a finality.

(Example) input display

ㅇ ㅇ

ㅏ ㅇㅏ

ㄴ ㅇㅏ ㄴ

ㅎ ㅇㅏ ㄴㅎ

If a consonant composed of two consonants or a double consonant is input and a consonant is input again, a Korean code is generated and the last consonant is used as a consonant for generating a new character. If a final word consisting of double consonants or double consonants is input and 'end' is input from the input unit 200, a Hangul code is generated using the input characters. Using this code, Hangul is output to the display unit 100.

(Example) Input: ㅇ ㅏ ㄴ ㅎ "End"

Indication: Not

If a vowel is input after a double consonant or a double consonant is input, a Korean code is generated using the consonants immediately before the last consonant, and the last consonant is used as the initial entry of a new letter.

(Example) Input: ㅇ ㅏ ㄴ ㅎ 'ㅏ'

Show me: No

If a consonant + vowel + consonant is input and a vowel is input without the input of "end", it generates a one-letter code with the consonant + vowel and the last consonant is used to create a new letter.

(Yes) Enter: No "ㅏ"

Indication: Ah

Before performing the Hangul code generation for the letters already entered, the user can move the input position (cursor) to correct arbitrary letters.

6 is a diagram illustrating a Jamo correction process according to an embodiment of the present invention. Immediately before completion of the combination of the letter 'han' through the above-described process of FIG. 5, that is, 'ㅎㅏㄴ _' is displayed on the display unit 100 (in this case, _ is the cursor K.) Direction so that it is below 'ㅏ'. In the state, when a new consonant '에서' is inputted, 'ㅏ' is erased, 'ㅓ' is written on the spot, 'ㅎㅓㄴ' is displayed, and when the input is completed, the letter 'Hun' is completed. The generation of the Korean code in the entire process occurs only once when the last 'Hun' is generated. That is, one Hangul code is generated until the letter 'Hun' is completed.

When combining and displaying the Hangul using the present invention, the Hangul code using only the information of each letter while the consonants and vowels are input, that is, until the letter is not completed, has only information on each letter. Since it generates, the number of times to execute the function to generate Hangul code is reduced, which can increase the system performance. For example, if you input '한', three Korean codes are required to generate Korean code in the order of 'ㅎ' → '하' → '한'. However, when generating Korean code in the order of 'ㅎ' → 'ㅎ' 'ㅏ' → 'ㅎ' 'ㅏ' 'ㄴ' → '한', you only need to generate the last Korean code once. In the present embodiment, the letter is treated as a separate letter before completing a letter, it is easy to modify the initial or neutral.

Hangul code of Hangul is composed of 19 initial characters, 21 neutral characters, and 27 final characters. Therefore, it is faster and more efficient to generate all 67 Jamo codes than to generate Korean codes.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention only displays each letter to be input when the letter is being input, and generates a Hangul code for the letter using the letter that has been input until the letter is completed. By reducing the required Korean code generation process, there is an effect to prevent the deterioration of overall system performance.
