Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing the present invention through the reference numerals added to the components of each drawing, it should be noted that the same reference numerals are used even when the same reference numerals are shown on the other drawings to indicate the same components.

Also, in the following description, many specific details such as components of specific circuits are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It is self-evident to those of ordinary knowledge in Esau. 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.

1 is an internal block diagram of a digital portable terminal that receives text information through a touch screen panel to which the present invention is applied and recognizes and processes the text information.

The digital portable terminal shown in FIG. 1 has a characteristic of further comprising a touch screen panel and a controller for processing touch screen panel data generated from the touch screen panel as a character information input means in a conventional digital portable terminal configuration. The touch screen panel is applied and implemented as a common touch screen panel which is already known and practiced. In addition, in the configuration of the digital portable terminal illustrated in FIG. 1, essential components in the operation of a digital portable terminal such as a dual tone multi frequency (DTMF) unit and a vocoder implemented in a typical digital portable terminal are omitted. This is because it is not directly related to the gist of the present invention. However, it will be apparent that the digital portable terminal to which the present invention is applied is actually provided with the above components as essential components.

Referring to FIG. 1, the configuration and operation of the digital portable terminal according to the present invention will be described. The controller 10 controls the overall operation of the digital portable terminal. In the embodiment of the present invention, the touch screen panel data generated according to the touch input in the touch screen panel 60 is recognized and corresponding processing is performed accordingly. The controller 10 is typically implemented by using a one chip microprocessor. In the case where the control unit is actually applied as a digital portable terminal, a chip commonly used is a 'mobile station modem (MSM) chip', which is manufactured and marketed by Qualcomm. The digital portable terminal in which the present invention is implemented may also achieve the use of the MSM. The controller 10 recognizes and processes the touch screen panel data applied from the touch screen panel 60 to read out a corresponding coordinate value of the input point. It is determined whether the user inputs some command or information through the read coordinate values. The touch screen panel 60 is an object-oriented information input means, when a user applies continuous pressure to a predetermined portion of the upper surface of the panel through a hand or a writing instrument, that is, if a desired character or information is written as a touch of the panel, Generates data and outputs it to the controller 10. While the conventional keypad generates the predetermined key data corresponding to the input key, the touch screen panel 60 outputs touch screen panel data that is continuously generated as a result of the user applying pressure on the screen. Accordingly, the keypad outputs only predetermined key data, but the touch screen panel 60 outputs various touch screen panel data according to a corresponding point at which an input is made, although not predetermined. The memory 20 is implemented by being divided into a volatile memory (eg, RAM) and a nonvolatile memory (eg, flash memory, EEPROM) area, and a program and initial service data that collectively controls the overall operation of the digital portable terminal. An operation program according to an applied touch screen panel data processing and predetermined data generated according to an operation execution are classified and stored. In addition, a buffer function is performed to temporarily store the processed data and necessary data. The memory 20 stores the display data of the marker icon displayed in the practice of the present invention. The marker icon is displayed in a portion designated as a touch area of the touch screen panel, and through the touch input thereof, a user can search for display information according to the present invention.

The display unit 40 is a user interface device that displays the overall state of the terminal and input user input information such that the user can visually know. This is typically implemented by using a liquid crystal display (LCD) in a portable terminal. In the embodiment of the present invention, the display operation is performed under the control of the controller 10. The information displayed on the display unit 40 may be information input through a keypad or information input through the touch screen panel 60. The LCD implemented as the display unit has a limit of information display of 128 X 64 dots in a portable terminal, which means that 8 Korean characters and 16 English characters can be displayed. Even in the case of other LCDs, the fact that the above information display capability is not greatly exceeded is a situation in the present. And the Korean characters displayed on the LCD are 8 characters because one Korean character occupies the display screen space of 16 X 16 dots, and in the case of English, 16 characters is the display screen space of 8 X 16 dots. It is due to occupy. In the case of Korean, 16 X 16 dots are defined as one character, and in the case of English characters, 8 X 16 dots are defined as one character. Therefore, in the case of a normal LCD or an LCD to which the present invention is applied, a maximum of 8 characters are displayed in Korean and 16 characters in English.

On the other hand, the conventional LCD is to display only a predetermined number of characters in this way, when it is required to display a sentence having more than the number of characters, it is not possible to display all of them on one screen, which is a display screen that the user needs information This brings several limitations to the recognition. In the end, it is the gist of the present invention to be described immediately below to solve this problem.

In addition, the screen display state of the display unit 40 according to the preferred embodiment of the present invention is shown in FIG. 3 and the description thereof will be made below. The wireless signal processing unit 50 performs overall processing for transmitting and receiving wireless signals between the digital portable terminal and the base station to which the terminal is subscribed. In general, an operation of converting a signal of a radio frequency band into an intermediate frequency and converting the converted intermediate frequency into a baseband is performed, and digitally converts the converted baseband signal to perform a corresponding processing. When the radio signal is transmitted, the operation is reversed. The key input unit 30 is used together with the TSP 60 as a user information input means at the same time, and includes a keypad having a plurality of numeric keys and function keys. The keypad inputs corresponding information by outputting its own key data according to the input of each provided key. Through the keypad operation in the key input unit 30, the user sets the necessary functions and performs the operations.

2 is a flowchart illustrating an information display method of a digital portable terminal having a touch screen panel according to an exemplary embodiment of the present invention as a character input unit. Referring to the drawings, a preferred embodiment of the present invention will be described. In operation 201, the user enters the text display mode according to a user's request and other causes. In step 220, it is determined whether there is a character required for display. In such a case, in step 230, the number of characters of characters required for display is compared with the number of characters of characters that can be displayed on the display screen of the terminal to which the present invention is applied. The number of characters of the displayable character may be determined as the number of characters that can be displayed in one line or may be the number of characters that can be displayed on the entire screen. If the number of characters of the character required to be displayed in step 230 is smaller than the number of characters that can be displayed on the display screen, since all the contents can be displayed on one screen, the corresponding character of the character to be displayed is displayed in step 270. This is the same as the character display operation of the conventional portable terminal. However, if the number of characters of the characters required to be displayed in step 230 is greater than the number of characters that can be displayed, in this case, the predetermined marker icon is controlled to be displayed on one side outside the display screen according to the embodiment of the present invention. In other words, if character display exceeding the display window area where the text is displayed is desired, if the marker icon is displayed as an annealing area, it is designated as another area which is distinguished from the display window area. In the portable terminal, the display of the reception strength, the battery remaining amount display, and the like are designated and displayed as an anneal area.

As shown in FIG. 4, the display form of the marker icon is determined in a predetermined form so that the user can easily touch the icon. The figure shows that the unmarked characters are in the form of arrows pointing in the corresponding direction so as to recognize that they are on the right or left side of the screen. A predetermined area of the touch screen panel corresponding to the display position of the marker icon is designated as the touch area. If the user has a touch input to the designated position, it is determined that the selected icon is displayed. In step 250, it is detected whether there is a touch input of the displayed icon. That is, it is determined whether the user touches a certain area of the touch screen corresponding to the displayed icon. In such a case, in step 260, a character corresponding to a character that is not displayed on the current display screen is displayed. In other words, when the user touches an icon, the screen is scrolled in a predetermined direction so that an undisplayed character is displayed. As you scroll, you will see another type of marker icon to indicate that there is a missing character in the previously displayed current state. This is as shown in FIG.

Referring to FIG. 2, referring to FIG. 4, first, in the case of (a), a text display method is shown in a typical portable terminal, and a user predicts an undisplayed text and inputs a direction key. The undisplayed letter will then appear. However, looking at the character display method according to the embodiment of the present invention as shown in (b), when the user touches the icon, the undisplayed character portion is displayed, there is a non-displayed character in the relative direction according to the display of the non-displayed character Will cause the icon to be displayed again. Therefore, the user can know that there is an undisplayed character on either side, and can perform the corresponding input so that the undisplayed character is more easily displayed.

3 is a diagram illustrating how a document to be displayed can be displayed from the user's point of view as a preferred embodiment of the present invention.

Referring to this, in step 310 it is determined whether there is a document display input. In this case, the user may check the received message, search the stored information, or the like. If there is a request for displaying a document, in step 320, it is determined whether there is content to be displayed further on the right side of the display document. That is, it is determined whether the undisplayed portion on the display screen is the right side of the displayed portion. This determination has been described previously in that it is the number of characters and the display position of the characters.

If there is content to be further displayed on the right side of the display document in step 320, the right marker icon is projected, that is, identified with the display document in step 325. In step 330, whether there is more content to be displayed on the left side, in step 340, whether there is more content to be displayed upward, and in step 350, it is determined whether there is more content to be displayed downward. According to the determination result of each step, entry to the next step is performed or the left marker icon is displayed in step 335, the upper marker icon is displayed in step 345, and the lower marker icon is displayed in step 355, respectively. If there are undisplayed document contents in two directions, the corresponding icon is displayed simultaneously in both directions.

Meanwhile, in the above description, the portable terminal is referred to as a representative case to which the present invention is applied. However, this is for convenience of description. It may be carried out after the deformation is applied to. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims below, but also by the equivalents of the claims.

As described above, the present invention has an advantage that a user can more easily search for necessary information in a digital portable terminal using a touch screen panel as an input means for information. In addition, according to the embodiment of the present invention there is an advantage that the sentence search of the long sentence provided by the Internet service is more convenient.
