The second camera module 121-2 has a photographing direction substantially opposite to that of the first camera module 121-1 (see FIG. 1), and may have different pixels from the first camera module 121-1 (see FIG. 1).

For example, the first camera module 121-1 has low pixels so that it is easy to capture a face of a user in the case of a video call or the like and transmit the face to the other party, and the second camera module 121-2 has a general object It is often desirable to have a high pixel.

A flash 121-3 and a mirror 121-4 may be further disposed adjacent to the second camera module 121-2. The flash 121-3 shines light toward the subject when the subject is photographed by the second camera module 121-2.

FIG. 4 is a block diagram illustrating a configuration of a portable terminal according to an exemplary embodiment of the present invention. Referring to FIG. 4, the display module 151, which is the output unit of FIGS. 1 and 2, As shown in FIG.

4, the portable terminal according to the present embodiment includes a flexible touch film 10 for generating a touch input signal according to a touch operation of an input medium, a flexible film 10 disposed on the same plane as the touch film, And a vibration driving unit (30) for vibrating the vibration film when the touch input signal is generated.

The touch film 10 is an element for generating a touch input signal by recognizing a touch by an input medium such as a user's finger or the like. In this embodiment, the touch film 10 is formed in a flexible property so as not to suppress the vibration of the vibration film . In addition, the position of the touch film may be a screen corresponding to a display module in a portable terminal, or may be disposed at another position. For example, when the input key is configured as a touch type rather than a button type, it can be arranged in the touch type input key. In addition, the input type key can be disposed on a side surface, a top surface, and a bottom surface of the portable terminal. That is, the touch film may be disposed at any portion of the portable terminal capable of generating a predetermined input signal by a touch by a user.

The vibration film 20 is a vibration-generating element that is substantially vibration-generating. The vibration film 20 has a flexible property to generate vibration. The vibration film 20 is disposed on the same plane on which the touch film is disposed, Respectively. The order of lamination between the vibration film and the touch film can be various.

Since the current touch film does not necessarily require contact with the surface of the touch film, the vibration film is disposed on the touch surface of the touch film, that is, The touch film 10 may be disposed between the films 20 and disposed on the back surface of the touch film, that is, as shown in FIG. 5B, a vibration film may be disposed between the body of the portable terminal and the touch film . In the case of the former, there is an advantage that stronger vibration can be applied to the input means. In the latter case, there is an advantage that the touch by the input means can be checked more precisely.

6, the touch film 10 and the vibration film 20 may be integrally formed. In this case, the touch film 10 and the vibration film 20 can be integrally formed. In this case, all the advantages of the method shown in FIG. 5 can be taken, This is possible.

Meanwhile, the vibration film 20 may be formed of a film speaker.

The film speaker is a speaker using a film for converting electric energy to vibration. Although it is good for high sound, it is not enough for a very low base or strong sound. However, there is no significant influence on the use of the vibration effect part as in this embodiment. Of course, in this case, noise is expected to occur due to vibration, but it is not a problem because adhesion with the touch film and suppression of noise generation due to frequency control are expected.

The vibration driver 30 is an element for driving the vibration film to vibrate the portion to which the touch operation is applied based on the touch input signal. The vibration driving unit may be formed of a conventional vibration generating member such as a haptic motor for generating vibration, but may be connected to the inside of the body of the portable terminal with respect to a support for supporting the motor in the case of a haptic motor Is high. This is contrary to the present embodiment in which only the touch portion made by the input medium is vibrated, not the whole portable terminal, so attention should be paid to placement. That is, when connecting the portable terminal body and the haptic motor, a shock absorber is added between the haptic motor and the haptic motor to minimize the movement of the haptic motor to the portable terminal body by vibrations. It is possible to consider a configuration in which a strong vibration is added to the vibration film by connecting.

As another method, it is possible to consider a method of applying a frequency which is a driving means of a film speaker as in a film speaker. In this case, the vibration driving unit 30 operates as a driving frequency generating unit.

It is preferable that the vibration driver vibrates only the portion to which the touch operation is applied by the input medium, but it is very difficult to realize this. Therefore, it is preferable that the entire vibration film is vibrated through means using a haptic motor or the like, or the entire vibration film is vibrated by applying a driving frequency. The overall vibration of the portable terminal is negligible compared to the vibration of the entire portable terminal as in the prior art because the vibration part of the vibration driving part is the main subject of the vibration film. Particularly, when the vibration film is structured such that a vibration is applied by a frequency like a speaker film, it is possible to make the vibrations of the connection part between the portable terminal body and the vibration film hardly according to the driving frequency applied by the vibration driving part, Only the vibration is possible. At this time, the vibration driving unit must apply a driving frequency to find a compromise with a frequency for vibrating the touch point by the input medium. If it is difficult to compromise the frequency setting for suppressing the vibrating part of the portable terminal body and vibrating the touch point, it is preferable to set the frequency for the vibrating part of the touch point. The reason for doing this is basically to add vibrations to the vibration film of flexible nature rather than to the body of the mobile terminal, so that the vibration of the vibration film is mitigated by the flexible property and transmitted to the body of the mobile terminal, This is because only vibration can be added. Particularly, in such a case, it is preferable to apply a frequency at which the vibration of the portion to which the touch operation is applied is maximized. Of course, the vibration of the vibration film is affected by the amplitude of the frequency applied by the vibration driving unit, but when the vibration is located at a point where there is no vibration in relation to the frequency, the change of the amplitude itself is meaningless, .

Vibration by Frequency The vibration pattern of the film surface has already been experimented in a vibrating body having a circular outer shape like a drum, and the result is known, so that it is possible to extract experiment data and store it in advance in the vibration driving unit. Of course, since the driving film applied to the portable terminal belongs to a small size due to the characteristics of the portable terminal, there is no problem to feel the vibration regardless of the frequency. However, in order to prevent the vibration size from changing depending on the position, Application of the driving frequency is required.

The driving frequency applied to the vibration film by the vibration driving unit may be applied such that the magnitude or period of the vibration varies according to the touch movement of the input medium as shown in FIG. In such a case, it is preferable that the case is performed in relation to the nature of a predetermined object being displayed on the portable terminal. For example, when the first object is dragged and moved to the destination object, a strong vibration or a rapid cycle of vibration when touching the first object, a weak vibration or a slow cycle of vibration when moving to the destination object, When the movement to the destination object is completed, another vibration effect such as a strong vibration or a rapid cycle vibration is given to improve the satisfaction of the user. Of course, such a configuration can be applied to the case of the haptic motor described above. However, for the period of vibration, the vibration portion due to the driving frequency will be more advantageous than the vibration portion due to the haptic motor or the like.

Examples of varying the magnitude or period of the vibration according to the touch movement such as drag can be calculated in various ways, but some examples will be described below.

FIG. 8 shows shooting related game contents that can be supported by the portable terminal. In this case, when a target is touched, a target point is formed and a strong vibration is generated to provide a more intuitive interface to the user. It also provides a shaking effect by changing the aim point. In addition, the weak vibration at the time of dragging may be utilized as means for indicating that the user is continuously touched and the aiming point is continuously displayed. When the aiming point is matched with the target during the drag operation, a strong vibration is generated again so that the user is aware that the target is located within the aiming point. In this case, more precise contents can be provided, and the position of the center of the aimpoint hidden by the input medium such as a finger can be perceived by the tactile angle, not by the time, so that accurate aiming is possible.

9 shows an example in which an alarm or a current time is set to an analog movement such as an hour hand, a minute hand, and a second hand instead of a numerical input.

In the case of an hour, minute, and second hand in a watch, it is difficult to adjust the time when it is enlarged by the user's selection, and it may be difficult to display on a touch screen of a predetermined size. Therefore, it is necessary to be able to recognize whether an accurate selection of various needles has been made without changing the size of the displayed hour, minute and second hands. This is accomplished through vibration, and the following problems arise when applying the conventional vibration effect. In the conventional vibration effect, since the magnitude of the vibration designated through the option menu is uniformly applied, the same vibration is generated even if the user selects any one of the hour hand, the minute hand, and the second hand. If the hour, minute, and second hands contain two or more touch media - If each needle is positioned adjacent to it, the user may be able to recognize that the needle has been selected through vibration, It can not distinguish whether it is selected. Therefore, the user has to take a method of confirming the needle to be moved according to the drag by dragging the input medium. In this case, if the unwanted needle is moved, it is necessary to return to the original position and then perform the reselection There is a presence. In this embodiment, particularly, by changing the frequency by applying the vibration effect using the driving frequency, the user can apply the distinguishable vibration effect. By controlling not only the magnitude of vibration but also the period of vibration, the user can clearly see which needle he or she has currently selected. For example, in the case of an hour hand, a long period of vibration, a second hand in a short period of vibration, and in the case of a minute hand, an intermediate period of vibration is generated so that the user can clearly recognize what the needle he / . Accordingly, the user can select the desired needle through the vibration that can be distinguished and then adjust it to the desired time through the drag. Also, by adding the vibration corresponding to the currently selected needle at the time of dragging, It is desirable to know that it is performing normally.

FIG. 10 shows a case where a selected object is stored in a folder. In this case, a television screen currently being watched is captured and stored in a predetermined folder.

When a user wishes to capture a desired scene while watching a television, the user first tries to stop the image by touching the screen at a desired instant. At this time, it is preferable that a predetermined folder is displayed at a predetermined position in the screen for storage, and the current still image is stored in the folder by dragging from the point where the touch is made to the folder. However, in this case, the user can confirm the selected image through the stop of the image, but there is no way to check whether the currently selected image normally moves according to the drag, and whether or not the storage in the folder is completed immediately. Therefore, in order to confirm this, the user has to stop watching the television and search the folder to see if the desired image is stored, which is inconvenient for the user.

According to the present embodiment, by adding a vibration effect when a selected image is dragged to a predetermined folder, the user can be informed that the selected image is normally in the process of storing, and by adding strong vibration to the folder, It is possible to recognize that the storage has been normally performed without directly checking the folder. Of course, in addition to the vibration effect, it is also possible to display the result of data movement or storage in a folder to the user, but it is advantageous to enjoy the program currently being watched in full through the vibration effect. In the above description, the image is stopped at the time of touching the screen. However, the television program can be continuously viewed regardless of the touch of the screen. When the user touches the screen during the television viewing, the user recognizes that the image of the touch point is captured through the strong vibration. The user can recognize that the user is moving to the desired folder without missing the captured image through the weak vibration at the time of dragging. It is possible to recognize that the captured image is normally stored through the strong vibration. This process will have no effect on programs that are continuously output, except for the inevitable part where the screen is hidden by the input medium by the user. That is, it is possible to capture a desired image without interfering with the television viewing by notifying the user whether the normal execution from the capture to the storage is performed on display or voicing, but by notifying the user through the tactile sense through the vibration. In this case, it is needless to say that it is possible to recognize the vibration period rather than the intensity of the vibration as described above.

FIG. 11 shows an object to which a scroll function is added. The current user confirms whether the current user is in the scroll state or not at a time point at which the user can scroll. However, in most cases, time-dependent scrolling, as we have seen, can lead to errors, and the position of the input medium at the time of scrolling must also be carefully positioned at the scroll position.

Hereinafter, a case in which the vibration effect according to the present embodiment is added will be described. The selection of objects in the currently displayed menu is done in a conventional manner. Of course, it is desirable to recognize that the object is selected through vibration when a predetermined object is selected.

If there is no desired object in the current menu to be displayed, the input medium is positioned at the upper and lower scroll positions of the screen to perform scrolling or scrolling according to the drag direction through the dragging on the screen. The vibration magnitude or cycle) to indicate that a normal scroll position has been selected, or to indicate that a normal drag for scrolling has been performed. The user is informed that the scroll limit has reached the limit of the scrolling during the scrolling through the above operation, that is, when the scroll end is reached, the scroll limit is reached through the vibration distinguished from the vibration during the scrolling. Of course, it is preferable that the vibration at the time of reaching the scroll limit point can be distinguished from the vibration at the time of selecting a predetermined object. According to this, the user can perform the scrolling in dependence on the tactile sense without depending on the time, thereby reducing the burden on the user's viewpoint.

12 shows the vibration film formed by a hinge coupling structure which can be folded. In order to arrange the vibration film on the hinge, it is required to fix the edge of the vibration film through the film guide portion. Particularly, in the case of such a hinge coupling structure, it is advantageous when a speaker film is applied as a vibration film. Of course, this is also the case when the speaker film and the touch film are integrated. In the case of the speaker film, the speaker film is disposed in the folder portion newly formed through the hinge coupling structure. . This means that it is possible to provide a speaker with higher output to the cellular phone. When the folder portion is closed, it serves as a vibration film. When the folder portion is opened, it operates as a speaker. At this time, the speaker film can be used as a microphone by reversing the principle of a speaker, and it is possible to provide a stereo sound by being spread out on both sides as shown in FIG.

In summary, the film guide portion for folding the vibrating film may include a hinge portion enabling folding use and a film fixing frame for fixing the outer portion of the vibration film. In this case, It is possible to provide stereophonic sound by forming the film guide part in two in the lateral direction or in the vertical direction as a standard.

However, in this case, two speaker films are placed on the touch film when folded to use the speaker film as a vibration film. In this case, both of the two speaker films can be used as the vibration film. However, when the film guide portions are all folded, it is sufficient to vibrate only the vibration film disposed on the film guide portion located at the upper portion. Of course, depending on the setting of the user, it may be possible to vibrate both the vibration film disposed below and the two vibration films disposed above and below.

FIG. 14 is a block diagram schematically illustrating a portable terminal according to another preferred embodiment of the present invention.

Referring to FIG. 14, the portable terminal according to the present embodiment includes a flexible organic light emitting device (FOLED) 70, a flexible organic light emitting device 70 disposed on the same plane as the FOLED, A flexible touch film 10 for generating an input signal, and a vibration driving unit 30 for vibrating the FOLED when the touch input signal is generated.

The FOLED 70 is an OLED that can be manufactured in the form of a film. In this embodiment, the FOLED 70 functions not only as a display, which is a basic function of the OLED, but also as a vibration film that vibrates by the vibration driving unit 30.

At this time, the FOLED 70 can be formed integrally with the touch film 10 as shown in FIG. If the FOLED and the touch film are separately provided, the stacking order of the FOLED and the touch film on the portable terminal body 50 can be variously applied.

That is, as shown in FIG. 15, the FOLED 70 may be disposed between the touch film 10 and the portable terminal body 50. Alternatively, the touch film may be disposed between the portable terminal body and the FOLED.

The vibration driver may drive the FOLED to vibrate a portion to which the touch operation is applied based on the touch input signal, and may generate the vibration through a driving frequency. At this time, it is preferable that the driving frequency is a frequency at which the portion to which the touch operation is applied is vibrated. Since the present embodiment uses FOLED as a vibration film in the end, it is also possible to devote specific contents to the vibration film. In addition, the FOLED 70 itself may be formed of a speaker film or a vibration film. In this case, the display and the vibration film can be simultaneously realized with at least one flexible film, and in the case of the hinge structure, the speaker can also be used. Furthermore, if the FOLED itself is provided with a function as a touch film, the FOLED may be used as a display, a vibration film, and a touch film as a single FOLED.
