The flexible display unit 120 is a display device capable of flexing according to external physical force.

The warp judging unit 130 judges at least one of a curvature, a warp range and a warp direction when the flexible display unit 120 senses warp. At this time, the operation of the warpage determining unit 130 may be controlled by the interface unit 160.

The warpage judging unit 130 can detect warpage using at least one film type piezoelectric film sensor that electrically changes the physical movement. At this time, the piezoelectric film sensor can be positioned behind the flexible display part 120 and outputs a resistance value of about 10 K? In a flat state. When the piezoelectric film sensor is bent over 90 degrees, an electric resistance value of 15 K to 30 K? May be provided to the warpage determining unit 130. The piezoelectric film sensor may be arranged as shown in FIG. 13.

FIG. 13 illustrates an example in which a piezoelectric film sensor is disposed to detect bending of the flexible display unit according to an exemplary embodiment.

Referring to FIG. 13, piezoelectric film sensors 1310, 1320, 1330, 1340, and 1350 are disposed in a shaded portion.

The bending determination unit 130 may determine the bending operation indicated by the dotted line using the sensing results of the piezoelectric film sensors 1310, 1320, 1330, 1340, and 1350.

The warp information determined by the warp determiner 130 may be as shown in FIG.

FIG. 2 is a view showing information determined when the flexible display unit according to the embodiment is bent. 2, the warpage determination unit 130 determines the warpage of the flexible display unit 120 based on the warp width 210 of the flexible display unit 120, the warp direction 220 of the flexible display unit 120, And so on.

The warpage determining unit 130 may check the curvature of the flexible display unit 120 using the sensing results of at least one or more piezoelectric film sensors and the warpage determining unit 130 may use the sensing results of the piezoelectric film sensors It is possible to detect the curved shape of the display unit 120 and calculate the width 210 and the curved direction 220 according to the deformed shape.

The touch sensing unit 140 senses touch information when the flexible display unit 120 is touched.

The storage unit 150 stores an operating system, application programs corresponding to layers, and storage data for controlling the overall operation of the user interface device 100.

The interface unit 160 sets a part of the flexible display unit 120 as a layered display area when the flexible display unit 120 is bent above a predetermined curvature and is output through the flexible display unit 120 to the layered display area. Layers are displayed hierarchically, and when a touch is detected in the layered display area, a layer corresponding to the touched layer is selected and displayed on the flexible display unit 120.

The interface unit 160 may control whether or not the warp determination unit 130 is operated. The interface unit 160 may control the warp determination unit 130 to operate only when a predetermined application is driven. That is, the interface unit 160 may serve an interface using the flexible display unit 120 when a predetermined application is operated.

At this time, the hierarchical layer is displayed on each page of the book when the e-book application is executed, a plurality of menu windows, mails transmitted and received by the e-mail application, and are currently being executed. Applications, etc. are possible, as well as all applications that can be displayed hierarchically.

The interface unit 160 sets the outer or corners of the side having the greatest curvature based on a predetermined reference line of the flexible display unit 120 as the layered display area.

3 is a diagram illustrating a reference line for setting a position of a layered display area in a user interface device according to an embodiment.

Referring to FIG. 3, the interface unit 160 may identify the direction of the greater curvature of the flexible display unit 120 using four reference lines having S, W, Z, and H as axes. However, the baseline can be made anywhere except S, W, Z and H.

4 is a diagram illustrating an example of setting a position of a layered display area in a user interface device according to an embodiment.

Referring to FIG. 4, as a result of determining the bending direction 410 of the flexible display unit 120, the maximum curvature 420 is distributed on the right side based on the W axis of FIG. 3, so that the interface unit 160 has a predetermined size on the right outer side. The layered display area 430 is set. In this case, the size of the layered display area 430 may be a predetermined size or may be changed according to the number of layers to be displayed in the layered display area 430.

Meanwhile, when the flexible display unit 120 detects the bending of the flexible display unit more than a preset curvature while the flexible display unit 120 is touched, as shown in FIG. 5, the interface unit 160 displays the layered display of the flexible display unit to the outside of the flexible display unit. You can also set it as an area.

5 is a diagram illustrating another example of setting a position of a layered display area in a user interface device according to an embodiment.

Referring to FIG. 5, when the interface unit 160 detects the flexible display unit 120 to bend more than a preset curvature while being touched, the interface unit 160 determines the touch position 510 as the start position of the layered display area 520. The outer edge of the flexible display unit 120 is set as the layered display area 520.

In this case, the outer edge of the layered display area 520 may consider the curved direction and the maximum curvature of the flexible display unit 120 as shown in FIG. 4, and consider the curved direction and the short outer edge of the flexible display unit 120. It may be.

When the touch detected in the layered display area selects a plurality of layers, the interface unit 160 selects a layer corresponding to the highest layer among the selected plurality of layers. Alternatively, when the touch sensed in the layered display area selects a plurality of layers, the interface unit 160 may select a layer having the largest touched area among the selected plurality of layers.

6 is a diagram illustrating an example of selecting a layer in a user interface device according to an embodiment.

Referring to FIG. 6, when the touch sensed in the layered display area 610 selects a plurality of layers, such as touch 1 620 and touch 2 630, the interface unit 160 is the highest among the selected plurality of layers. Select the layer corresponding to the layer. That is, the third layer is selected in the case of touch 1 620, and the second layer is selected in the case of touch 2 630.

As can be seen through Figure 6, when the present invention is applied to a book viewing application, the interface for detecting the bending and touch of the flexible display unit 120 gripping and holding the book in a bent and bent state By flipping a book through a wrist and a finger, an intuitive interface for flipping through a bookshelf may be provided, or a bookshelf flipping through a subdivided sliding of a thumb may be provided as an intuitive interface for holding and dividing a book.

This intuitive interface minimizes the effort to acquire the user's interface with the interface created based on the experience that the user has learned in real life.

In addition, when the touch detected in the layered display area selects a plurality of layers, the interface unit 160 may select a layer corresponding to the lowest layer or a layer located at the center of touch.

When a touch is sensed in the layered display area, the interface unit 160 may not display a layer higher than the touched layer in the layered display area and may resize the layered display area. That is, the interface unit 160 may reduce the size of the upper layer that does not display the size of the layered display area and increase the size of the area where the layer is displayed by the reduced size.

When a touch is detected in the layered display area, the interface unit 160 scrolls in a direction of selecting a lower layer from the touched layer, and then sequentially displays a layer corresponding to the selected lower layer to be scrolled in the order of selecting the layer. It is displayed on the unit 120.

When the interface unit 160 sequentially displays the layers corresponding to the lower layers scrolled and selected on the flexible display unit 120 in the order of selection, the interface unit 160 is displayed with the effect of the bookshelf crossing or the currently displayed layer is displayed. The selected layer can be displayed by sliding it, or applying a vanishing effect to the currently displayed layer.

The interface unit 160 may adjust the speed at which the bookshelf passes, the speed at which the currently displayed layer slides, and the speed at which the currently displayed layer disappears according to the scroll speed. In other words, faster scrolling speeds up the layer disappearing effect, while slower scrolling speeds up the layer disappearing effect.

When the last layer is selected by the touch, the interface unit 160 may display a layer corresponding to the last layer and place the layers displayed in the layered display area next to the last layer to display the layer in the layered display area.

The interface unit 160 may vary the method of aligning the layers output through the flexible display unit 120 according to the shape of the flexible display unit 120 being convex or concave.

FIG. 7 is a diagram illustrating an example in which a flexible display unit is bent in a user interface device according to an exemplary embodiment.

Referring to FIG. 7, (a) illustrates a state where the front surface of the flexible display unit 120 protrudes convexly, and (c) illustrates a cross section of the flexible display unit 120 in the state (a). Drawing.

(b) illustrates a state in which the flexible display unit 120 is recessed and concavely curved, and (d) illustrates a cross section of the flexible display unit 120 in the state (b).

When the flexible display unit 120 is in the (a) state, the interface unit 160 may arrange the layers in the ascending order and display them in the layered display area 710. When the flexible display unit 120 is in the (b) state, the interface unit 160 may arrange the layers in descending order and display the layers in the layered display area 720.

For example, when the layers are pages included in the e-book, the interface unit 160 displays pages after being currently displayed in the layered display area 710 in ascending order. The interface unit 160 sorts and displays the previous page currently displayed in the layered display area 720 in descending order.

Meanwhile, when the hierarchically displaying layers output through the flexible display unit are hierarchically displayed on the hierarchical display area, the interface unit 160 may also display layer information for classifying the layers. For example, if the layers are pages of e-book, the number of pages may be displayed on each layer, or the number of contents may be displayed.

The controller 110 may control the overall operation of the user interface device 100. In addition, the controller 110 may perform a function of the interface unit 160. The control unit 110 and the interface unit 160 are shown separately to describe each function. Accordingly, the controller 110 may include at least one processor configured to perform each function of the interface unit 160. In addition, the controller 110 may include at least one processor configured to perform some of the functions of each of the interface units 160.

If the bending of the flexible display unit is smaller than the preset curvature in operation 814, the user interface device 100 returns to operation 810.

If the bending of the flexible display unit is equal to or greater than a predetermined curvature in operation 814, the user interface device 100 sets a part of the flexible display unit as a layered display area in operation 816.

In this case, the UI device 100 may set an outer edge or a corner of the flexible curvature on the basis of a preset reference line as the layered display area. Alternatively, when the flexible display unit detects the bending of the flexible display unit beyond a predetermined curvature while the flexible display unit is touched, the user interface device 100 may set the outer edge of the flexible display unit as a layered display area starting from the touched position. .

In operation 818, the UI device 100 hierarchically displays layers output through the flexible display unit in the hierarchical display area.

In operation 820, the user interface device 100 detects whether the user interface device touches the layered display area.

In operation 820, when the touch is detected in the layered display area, the user interface device 100 selects a layer corresponding to the touched layer and displays it on the flexible display unit. In this case, when the touch detected in the layered display area selects a plurality of layers, the user interface device 100 selects a layer corresponding to the highest layer among the selected plurality of layers. In addition, the UI device 100 does not display a layer higher than the touched layer in the layered display area and readjusts the size of the layered display area.

In operation 824, the user interface device 100 checks whether a scroll input is detected in the layered display area.

In operation 824, when the scroll is detected in the layered display area, the UI apparatus 100 sequentially displays layers corresponding to the lower layers scrolled and selected in step 824 in the order of selection.

If no touch is detected in the sensing result layered display area in step 820 or if scroll is not detected in the sensing result layered display area in step 824, the algorithm ends.
