Technical Field [0001] The present invention relates to a display apparatus and method capable of adjusting a content size,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device and a method thereof, and more particularly, to a display device and a method capable of adjusting the size of contents while minimizing a touch on the display screen.

In general, in order to enlarge content displayed on a touch screen of a display device, a user places his / her two fingers on a touch screen on which content is displayed and enlarges or reduces the content using two fingers.

Such a conventional method of enlarging and reducing contents has a high possibility that not only fingerprints such as fingerprints are generated on the touch screen but also foreign substances are buried on the touch screen since the user must put his finger directly on the touch screen . As a result, the problem of deteriorating the touch sensing function of the touch screen, which detects a user's touch, is caused by the above problem.

In addition, the conventional methods of expanding and reducing contents can be balanced by balancing the fingers of two fingers to enlarge or reduce contents. That is, if the fingers of the two fingers for enlarging or reducing the content are not balanced, the touch screen does not correctly detect the touch of the enlargement or reduction of the content, .

Meanwhile, the conventional method of expanding and reducing contents can enlarge a specific area desired by a user without using two fingers in connection with expansion of contents. That is, although a specific area desired by the user can be enlarged and displayed through the magnifying glass function, such a conventional magnifying glass function needs to touch an accurate point with respect to an area the user wants to enlarge. That is, it is possible to enlarge the area desired by the user with a minimum amount of touch. However, if the user does not accurately touch the desired area, the touch screen enlarges and displays the area that the user does not desire.

The first area 1-4 is located at a vertex on the display screen 210, (5-8) are located between the plurality of first regions. According to an embodiment, a second region 5 may be formed between the first regions 1 and 2, and a second region 6 may be formed between the first regions 3 and 4. A second region 7 may be formed between the first regions 1 and 3 and a second region 8 may be formed between the first regions 2 and 4. The third area 9 is a touch area for reducing the content, and may be located at the center on the display screen 210 according to the embodiment. The first region 1-4, the second region 5-8, and the third region 9 may be displayed in different colors. Accordingly, the user can select and touch an area to be touched through colors displayed on the outer and center areas on the display screen 210. [

On the other hand, the sensing unit 120 determines whether touches of different predetermined areas among the first area 1-4 and the second area 5-8 formed in the outer area on the display screen are continuously performed by the user Detection. If it is detected by the user that touches on different predetermined areas are consecutively performed, the controller 130 displays the contents in a direction corresponding to the sensed touch area according to the size adjustment step information stored in the storage unit 140 Expand it step by step. Herein, the size adjustment step information stored in the storage unit 140 is information set by the user so as to enlarge or reduce the size of the contents step by step.

FIG. 3 is an exemplary diagram for gradually enlarging the overall size of contents displayed on a display screen according to an embodiment of the present invention.

As shown, for example, in a state where contents are displayed on the display screen 210, the user can continuously touch the first area 1, 4. In this case, the sensing unit 120 senses that touches to the first area 1, 4 are continuously performed. Accordingly, the control unit 130 adjusts the overall size of the content to be enlarged according to the size step adjustment information stored in the storage unit 140, to a size of the first step. That is, the control unit 130 enlarges the content in a size corresponding to the first step while maintaining the ratio of the width and the height of the content, according to the size adjustment information stored in the storage unit 140. [

Thereafter, the display unit 110 displays the contents enlarged and adjusted in the size of the first step on the display screen 210 by the control unit 130. Thus, on the display screen 210, the entire enlarged contents corresponding to the first step are displayed while the width and the height are maintained.

If the touch of the first area (1, 4) is continuously performed in a state where the entire contents size is enlarged to the size corresponding to the first step, the controller (130) Adjust to increase the size. That is, the control unit 130 enlarges the content to a size corresponding to the second step while maintaining the ratio of the width and height of the content according to the size step adjustment information stored in the storage unit 140. [ If the user touches the first area (1, 4) continuously, the controller 130 controls the maximum size of the content corresponding to the preset size adjustment step information while maintaining the ratio of the width and height of the content The entire size of the content can be gradually increased until the enlargement step.

Meanwhile, in the present invention, when the user touches the first area (1, 4), the operation of enlarging the overall size of the contents while maintaining the ratio of the width and the height of the contents is described. However, the present invention is not limited to this, and if touches to different first areas among the first areas 1-4 are continuously performed, as described above, The total size of the contents can be enlarged.

4 is an exemplary diagram illustrating a magnification of a content displayed on a display screen according to an exemplary embodiment of the present invention in a specific direction.

As shown, for example, in a state where contents are displayed on the display screen 210, the user can continuously touch the second area 5,6. In this case, the sensing unit 120 senses that touches to the second areas 5 and 6 are continuously performed. Accordingly, the control unit 130 adjusts the overall height of the content to be enlarged according to the size step adjustment information stored in the storage unit 140 in the size of the first step. That is, the controller 130 adjusts the contents to be vertically enlarged according to the size step adjustment information stored in the storage unit 140 by a size corresponding to the first step.

Then, the display unit 110 displays on the display screen 210 the contents enlarged and reduced by the size of the first step by the control unit 130. Accordingly, the contents enlarged and reduced by the size corresponding to the first step are displayed on the display screen 210.

In this case, the entire contents can not be displayed on the display screen 210. In this way, for example, the user can touch the second area 6, 7 continuously while the overall size of the contents is enlarged to the maximum size enlarging step. As described above, when the second areas 6 and 7 are continuously touched, the controller 130 displays the C area on the display screen 210 among the A, B, C, and D areas corresponding to the fourth quadrant of the contents . According to such a control command, the display unit 110 displays the entire C region out of the A, B, C, and D regions corresponding to the quadrant of the content on the display screen 210. [ Thus, as shown in FIG. 6 (b), the entire C region of the content and a part of the remaining regions can be displayed on the display screen 210.

As another example, the user can touch the first area 4 and the second area 7 continuously. As described above, when the first area 4 and the second area 7 are continuously touched, the controller 130 determines whether the areas C, D among the areas A, B, C, and D corresponding to the fourth quadrant of the content are displayed And controls to be displayed on the screen 210. In accordance with such a control command, the display unit 110 displays the content shifted in the upward direction on the display screen 210. Accordingly, the C and D regions of the A, B, C, and D regions corresponding to the fourth quadrant of the content can be displayed on the display screen 210 more than the A and B regions.

As described above, the user can continuously move the content by touching the first area 1-4 or the second area 5-8 without touching the center area on the display screen 210.

Accordingly, the sensing unit 120 senses whether the touch from the user to the third area 9 is continuously performed. If it is detected that the third region 9 is continuously touched, the controller 130 displays the content displayed on the display screen 210 in a stepwise manner according to the size adjustment step information stored in the storage unit 140 . That is, in accordance with the size adjustment step information stored in the storage unit 140, the controller 130 maintains the ratio of the width and height of the content, and when the total size of the content is reduced by a size corresponding to the preset size adjustment step information Respectively. According to such a control command, the display unit 110 can display the reduced-size contents on the display screen 210.

According to the embodiment, when it is detected that the touch of the third area 9 is touched twice in succession, the controller 130 enters the reduction operation mode. If at least one touch of the third region 9 is sensed within a predetermined period of time through the sensing unit 120 in the reduced operation mode, the controller 130 controls the first So that the total size of the contents is reduced to a size corresponding to the step. In accordance with the control command, the display unit 110 displays the content on the display screen 210 having a size corresponding to the first step.

Thereafter, if at least one touch of the third region 9 is additionally sensed within a predetermined time by the sensing unit 120, the control unit 130 determines whether or not the touch of the third region 9 corresponds to the second step So that the total size of the contents is reduced. In this manner, when at least one touch of the third region 9 is detected within a preset time period through the sensing unit 120 in the reduced operation mode, The total size of the contents can be reduced by a step.

The operation of enlarging or reducing the size of the content displayed on the display screen 210 has been described in detail while minimizing the touch on the center area on the display screen 210 in the display device through various embodiments. Hereinafter, a method of adjusting the size of contents displayed on the display screen in the display apparatus according to the present invention will be described in detail.
