Dual folder mobile phone with sliding cover {DUAL FOLDER MOBILE PHONE HAVING SLIDING COVER}

The present invention relates to a dual folder mobile phone having a sliding cover, and more particularly, to a dual folder mobile phone having a main display and an auxiliary display on both sides of a front folder, in which a touch panel is mounted along the front of the auxiliary display. The present invention relates to a dual-fold mobile phone having a sliding cover that has a sliding cover that slides up and down to adjust the exposed screen size of the auxiliary display in two stages.

Recently, mobile phones are becoming a necessity rather than an optional commodity due to the convenience of use. Reflecting this trend, almost everyone owns a mobile phone, and handset makers are launching various types of products with improved designs and functions to induce consumer interest and purchase.

Cell phones must be light in size or weight because they must be carried by the user at all times. In addition, since it is used by various kinds of general users rather than a specific layer, it should be convenient and not complicated. In recent years, thanks to technological advances, mobile phone functions have gone beyond simple phone functions to enable games, electronic diaries, the Internet, and video playback, so that the level of PDA (Persnal Digital Assistant) or Palm Computer It is a reality comparable to that. Therefore, in order to satisfy such convenience of use and to facilitate the provision of various functions, the mobile phone should have a large display screen in addition to the input device such as a keypad.

In order to meet the various conditions required for the mobile phone, a step forward in a folder-type mobile phone having a keypad on the rear folder and a display only on the inner surface of the front folder, a small secondary display on the outer surface of the front folder Mobile phones equipped with the proposed have been widely used. The structure of a mobile phone having two displays in the front folder is commonly referred to as a "dual folder" mobile phone. A conventional dual folder mobile phone is shown in FIG.

1 is a perspective view of a conventional dual folder mobile phone, FIG. 1A shows a closed state of a front folder of a dual folder mobile phone, and FIG. 1B shows a state of opening a front folder. As shown in Figures 1a and 1b, the conventional dual folder mobile phone 10 is composed of a front folder 12 and a rear folder 15, when the user opens the front folder is mounted on the inner surface of the front folder The full screen is displayed through the main display 13, and when the front folder is closed, the date, time, battery level, electric field strength, and caller information are displayed through the auxiliary display 14 mounted on the external surface. Therefore, the user can check the necessary simple information even in the reception waiting state of closing the folder.

However, in the case of such a dual folder mobile phone 10, the information that can be displayed is limited due to the narrow size of the auxiliary display 14, so there is a problem that only simple information can be confirmed. In addition, since the keypad, which is the main input means of the cellular phone, is hidden in the state where the front folder 12 is closed, it is inconvenient to open the front folder in order to operate the cellular phone.

In addition, since the keypad of the conventional mobile phone has only a limited number of buttons, such as a numeric button and a simple operation button, it is inconvenient to function as an input means. For example, in order to input a character such as a Korean alphabet or an alphabet to record a text message or a memo, there is a need to repeatedly press a button several times to select / enter a required character.

In order to solve this problem, a technology has been proposed in which a touch panel is mounted on the front of a display of a mobile phone so that a user can input necessary information by pressing a touch panel with a pen or a fingertip. In this case, the user can select a menu displayed on the display of the mobile phone by using a pen or a fingertip, or input text directly on the touch panel. There was an advantage to overcome the limitations.

As such a method of mounting the touch panel on the display of the mobile phone, there is a method of mounting the touch panel on the main display of the dual folder and a method of mounting the touch panel on the display of the general mobile phone instead of the dual folder.

However, when the touch panel is applied to the dual folder, when the user opens the front folder, the main display is positioned above the antenna. Therefore, in order to use the touch panel stably, the front folder and the antenna must be wrapped together by hand. . Therefore, not only the transmission and reception performance of the mobile phone can be degraded, but also it is difficult to hold the front folder stably due to the shape of the protruding antenna, which makes it difficult to press the touch panel accurately and stably.

In addition, when the touch panel is mounted on the display of a general mobile phone other than the dual folder, the mobile phone can not be folded and its overall size becomes large, which makes it inconvenient to carry and also exposes the touch panel and the display to the outside. There was a problem that can be damaged.

The present invention has been proposed to solve the above problems, and the object of the present invention is to use the considerable functions of the mobile phone even when the front folder is closed with the ease of carrying through the miniaturization of the size, which is an advantage of the dual folder mobile phone. It is to provide a dual-fold mobile phone having a sliding cover that can provide convenience in use.

In other words, the present invention, by forming the size of the secondary display mounted on the front folder of the dual-folder mobile phone at least as large as the main display size can display the information required by the user even when the front folder is closed, the secondary display The touch panel is mounted on the front of the front panel to allow free input processing even when the front folder is closed, and a sliding cover that slides and opens and slides a certain area of the auxiliary display to protect the large display from the external shock. , Dual-fold mobile phone with a sliding cover that can configure the screen mode displayed through the secondary display in the closed and open state of the sliding cover differently to reduce battery usage and provide convenience for use The purpose is to provide.

Hereinafter, with reference to the accompanying drawings will be described in detail the advantages, features and preferred embodiments of the present invention.

Figure 2 is a perspective view of a dual-fold mobile phone having a sliding cover according to the present invention, Figure 3 is a cross-sectional view of the front folder according to the present invention, Figures 2a and 3a shows a state in which the sliding cover 34 is closed 2B and 3B are views illustrating a state where the sliding cover is opened. Referring to Figures 2 and 3 will be described below the configuration of a dual-fold mobile phone having a sliding cover according to the present invention.

Dual-folder mobile phone 20 having a sliding cover according to the present invention, the keypad, the antenna and the internal processing module, the rear folder 40 and the battery is attached to the upper end of the rear folder by the rotating shaft 22 The front folder 30 is formed to be opened and closed up and down. In addition, the front folder 30 may include a main display 31 mounted toward an inner surface, an auxiliary display 32 mounted toward an outer surface, a touch panel 33 mounted on a front surface of the auxiliary display, an auxiliary display, and a touch panel. A sliding cover 34, a speaker 35, a magnet 36 for detecting whether the sliding cover is opened or closed, and a cover detecting means 37 are provided. Since the basic configuration of the mobile phone 20 according to the present invention is the same as a conventional dual folder mobile phone, detailed description thereof will be omitted.

The front folder 30 according to the present invention includes a main display 31 as an inner surface and an auxiliary display 32 as an outer surface, so that the auxiliary display is largely formed to occupy a substantial portion of the outer surface of the front folder. do. Preferably, the secondary display 32 is formed to be at least the same size as the main display 31. Therefore, unlike the conventional dual folder mobile phone, even when the front folder 30 is closed, the user needs detailed information in addition to the basic information (date, time, battery level, electric field strength and caller information, etc.) through the secondary display ( Text message content, mobile phone operation screen, game or video content, etc.) can be displayed.

In addition, the touch panel 33 is mounted on the front surface of the auxiliary display 32 so that the user can directly open the front folder 30 and make necessary input directly without using the keypad. Accordingly, the user can use various functions such as checking / input and sending of a text message or manipulation of a mobile phone through the touch panel 33 even when the front folder 30 is closed.

As described above, when the size of the auxiliary display 32 exposed to the outside of the mobile phone 30 is large and the touch panel 33 is mounted on the front of the mobile phone 30, the touch panel or the auxiliary display may be damaged by an external shock. Can be damaged. In order to solve such a problem, the present invention is provided with a sliding cover 34 mounted on the front of the auxiliary display 32 and the touch panel 33 to cover a predetermined area of the auxiliary display screen. In addition, the touch panel may not be mounted on the upper end of the auxiliary display that is exposed to the outside even when the sliding cover is closed.

The sliding cover 34 according to the present invention has a size and a shape that can cover an area except the upper end of the auxiliary display 32, and both side ends are formed on both side ends of the front folder 30. ), The auxiliary display is opened and closed while moving up and down along the rail. That is, as the sliding cover 34 is opened and closed, the size of the exposed screen of the auxiliary display 32 is adjusted to two levels. Therefore, when the sliding cover 34 is closed as shown in FIGS. 2A and 3A, only the upper end portion of the auxiliary display 32 is exposed to the outside as in the auxiliary display of the conventional dual folder mobile phone, and as shown in FIGS. 2B and 3B. Opening the sliding cover down exposes the entire screen of the secondary display to the outside, allowing the user to operate and use the mobile phone.

In this case, it is preferable that the screen displayed through the auxiliary display 32 when the sliding cover 34 is closed and opened is formed in different modes. That is, when the sliding cover 34 is closed, the basic information such as date, time, battery level, electric field strength, and caller information are displayed as in the conventional dual folder mobile phone (reduction mode), and the main display when the sliding cover is opened. As shown in (31), the entire screen is activated and displayed (full mode). In general, when displaying the full screen, only the remaining battery level and the electric field strength are displayed on the upper portion of the display, and the remaining information (date, time, caller information, etc.) is displayed on the center or the lower portion of the display. If the overall mode is maintained even when the sliding cover 34 is closed, only the partial information displayed on the upper part of the auxiliary display 32 appears, so that the user has to open the sliding cover again to check caller information or time. There is a ship. Therefore, the present invention is to provide a mode change according to the opening and closing of the sliding cover 34 to solve this inconvenience. In addition, the mobile phone 20 according to the present invention is to reduce the consumption of the battery by turning off the backlight when the sliding cover 34 is closed.

In order to change the screen mode of the auxiliary display 32 according to the opening and closing of the sliding cover 34, a means for detecting the opening and closing of the sliding cover is required. The mobile phone according to the present invention has a magnet 36 for this purpose. And a cover detecting means 37.

Dual folder mobile phone having a sliding cover according to the present invention has a magnet 36 to the inside of the sliding cover 34, the side of the auxiliary display 32, the cover detecting means for detecting the magnetic force of the magnet ( 37), the magnet and the cover detecting means to be arranged in a position facing each other in the sliding cover is closed. Therefore, the cover detecting means 37 continuously detects the magnetic force of the magnet 36 when the sliding cover 34 is closed, and if the sliding cover is opened, the positions of the magnet and the cover detecting means are shifted from each other. Undetectable or sensed magnetic force is weakened to recognize it. The cover detecting means 37 generates an interrupt signal upon detecting the open state of the sliding cover 34, and the interrupt signal is input to the processor of the cellular phone. When the processor receives the interrupt signal, the processor converts the screen mode of the auxiliary display 32 from the reduced mode to the full mode and outputs the converted mode.

When the sliding cover 34 is closed again in the open state, the cover detecting means 37 detects the magnetic force again and generates an interrupt signal, and the processor receives the interrupt signal and outputs the reduced mode signal to the auxiliary display 32. do.

Figure 4 is a block diagram for explaining the operation of the dual-fold mobile phone with a sliding cover according to the present invention. Referring to Figure 4 describes the operation of the mobile phone according to the present invention as follows.

The signal D_KEY input by the user through the keypad 41 while the front folder 30 is opened is transmitted and processed to the processor 4, and the processor sends an output signal D_DISP1 to the main display 31. . In addition, when the front folder 30 is closed, the folder detecting means 42 for detecting the opening and closing of the front folder generates an interrupt signal INT1, and the processor 44 receives the INT1 and stops the output to the main display 31. And output signal D_DISP2 to secondary display 32. The output signal D_DISP2 at this time is an output signal for the reduced mode of the auxiliary display 32 when it is assumed that the sliding cover 34 is closed. That is, basic information including date, time, battery level, electric field strength, and the like. In addition, the output signal D_DISP2 may be output to the auxiliary display 32 regardless of whether the front folder 30 is opened or closed.

In the standby state in which the sliding cover 34 is closed, the cover detecting means 37 detects the magnetic force from the magnet 36 and generates a separate signal, and the processor 44 continues to reduce to the secondary display 32. Outputs the mode output signal D_DISP2. However, when the user opens the sliding cover 34, the positions of the magnet 36 and the cover detecting means 37 are shifted from each other, and the cover detecting means detects that the sliding cover is open to generate an interrupt signal INT2. . When the processor 44 receives the INT2, the processor 44 outputs the output signal D_DISP3 for the full mode to the sub display 32 to convert the screen of the sub display to the full mode. In addition, the processor 44 activates the touch panel control means 43 so that the touch panel 33 can be used when INT2 is input. In addition, the cover detecting apparatus 37 may generate a separate signal for the state in which the sliding cover 34 is closed, and the processor 44 may output the D_DISP2 according to the corresponding signal.

The user presses the touch panel 33 mounted on the auxiliary display 32 to input the touch panel, and the touch panel generates an analog signal A_POS containing the position information pressed by the user, and the generated A_POS is a touch panel control means ( 43). The touch panel control means 43 generates an interrupt signal INT3 to the processor 44 upon receiving the A_POS, and converts the coordinate value of the position where the touch panel 33 is pressed through the A_POS signal into the digital signal form D_POS. The processor 44 processes the D_POS and outputs the output signal D_DISP3 to the auxiliary display 32.

FIG. 5 is a diagram illustrating a state of use of a dual-fold mobile phone having a sliding cover according to the present invention, which sequentially shows a state of use when a text message arrives during use.

When the cellular phone 20 is waiting for a call, the processor 44 outputs the output signal D_DISP2 in the reduced mode to the auxiliary display 32 to display basic information (date, time, battery level and electric field strength, etc.) (Fig. 5a). In this case, when the text message is received, a message indicating the reception of the message is displayed on the auxiliary display screen (FIG. 5B).

When the user pushes down the sliding cover 34 in this state, the cover detecting means 37 detects this and transmits the INT2 signal to the processor 44, and the processor outputs the output signal D_DISP3 to the auxiliary display 32. To switch to full mode. In this case, since the user wants to check the text message, the content of the text message is automatically displayed (FIG. 5C).

The user checks the contents of the text message and makes the necessary input through the touch panel 33. FIG. 5D illustrates an example in which the user selects the 'BACK' button displayed on the auxiliary display 32 using the pen 50. The A_POS signal is input to the touch panel control means 43 with respect to the user's input, which is converted into a D_POS signal by the touch panel control means, and input and processed by the processor 44. Since the user selects the 'BACK' button in FIG. 5D, the processor 44 outputs the mail inbox screen, which is the previous screen, through the auxiliary display 32 (FIG. 5E).

If the user closes the sliding cover 34 in FIG. 5C, the processor 44 outputs the D_DISP2 signal to convert the auxiliary display 32 to the reduced mode (FIG. 5A). In addition, in FIG. 5C, when the user selects the 'REPLY' button, the text message is converted into an input / edit screen of the text message, and the user may select a soft keyboard in the form of an icon or write letters directly on the touch panel.

6 is a cross-sectional view showing a first modification of the front folder according to the present invention, such that the magnet 36 and the cover detecting means 37 face each other when the sliding cover 34 of the mobile phone 20 is completely opened. The modification which changed the position of the magnet was shown.

As shown in FIG. 6A, since the positions of the magnet 36 and the cover detecting means 37 are shifted from each other in the state in which the sliding cover 34 is closed, the cover detecting means does not detect the magnetic force. However, when the sliding cover 34 is opened as shown in FIG. 6B, the magnet 36 and the cover detecting means 37 face each other, so that the cover detecting means detects the magnetic force. Thus, the cover detecting means 37 generates an interrupt signal INT2 to cause the processor 44 to switch the auxiliary display 32 to full mode.

In addition to the method of detecting whether the sliding cover is opened or closed using a magnet as described above, an electrical or physical contact point may be used between the front folder 30 and the sliding cover 34, which is illustrated in FIG. 7. FIG. 7 is a cross-sectional view showing a second modification of the front folder according to the present invention, and shows a modification including a projection 38 formed to protrude a predetermined size downward and a button 39 pressed by the projection.

In the state in which the sliding cover 34 is closed as shown in FIG. 7A, the protrusion 38 is in a state of pressing the button 39. However, when the sliding cover is opened as shown in FIG. 7B, the protrusion is lowered and the pressure of the protrusion applied to the button is lowered. Is released, so the button is raised. Accordingly, a separate sensing means (not shown) connected to the button 39 may detect opening and closing of the sliding cover 34, and input an interrupt signal according to the processor 44 to display the screen mode of the auxiliary display 32. Will be converted.

As described above, the dual-fold mobile phone having a sliding cover according to the present invention, the user can operate the mobile phone by viewing the desired information on the secondary display and input through the touch panel even without opening the front folder. In addition, the sliding cover has a remarkable effect of protecting the auxiliary display and the touch panel from external impact.

In other words, a dual folder mobile phone having a sliding cover according to the present invention,

First, by forming the secondary display at least the same size as the main display, it is possible to display the full screen required by the user in addition to the basic information displayed through the secondary display of the conventional dual-folder mobile phone,

Second, by attaching the touch panel, an input device that is easier to use than the keypad, to the secondary display, the mobile phone can be operated even when the front folder is closed, and it can overcome the inconvenience or limitation of input through the keypad.

Third, the auxiliary display and the sliding cover that can adjust the size of the exposed area of the touch panel can be prevented from being damaged by the external display or touch panel,

Fourth, by changing the screen mode of the secondary display by detecting whether the sliding cover is opened or closed, not only increases convenience of use, but also reduces battery consumption by turning off the backlight when the sliding cover is closed.

Lastly, the sensing means for detecting the opening or closing of the sliding cover can be modified in various forms, such as a wide range of applications and deformation.
