Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an electronic device 100 in accordance with an embodiment of the present invention. Referring to FIG. 1, a body 110 and a flexible display 103 of the electronic device 100 are shown in FIG. The electronic device 100 may be a TV, a cellular phone, a tablet PC, or the like. The main body 110 may include a driving unit 101, a control unit 105, and a sensing unit 107. In addition, the main body 110 may be provided with a storage space for storing the flexible display 103 therein.

The flexible display 103 may be wound into the main body 110 or be removably mountable from the main body 110. The flexible display 103 can be driven by the driving unit 101 and automatically taken out of the main body 110. [ Or the flexible display 103 can be manually pulled out of the main body 110. [ When the flexible display 103 is drawn out from the main body 110, the display area may be exposed to the outside. The display area is an area where a part of the flexible display 103 is drawn out from the main body 110 and exposed to the outside. On the other hand, a part of the flexible display 103 wound in the main body 110 may be referred to as a screen off area. In other words, the flexible display 103 may include a screen-off area and a display area.

The size of the display area can be changed according to the amount of the flexible display 103 to be drawn out from the main body 110. Also, the size of the screen off area can be changed according to the amount of the screen 110 to be drawn out from the main body 110.

The driving unit 101 can take out the flexible display 103. The driving unit 101 may include an actuator and the flexible display 103 may be drawn out of the main body 110 by an actuator. For example, the driving unit 101 may include a motor and a gear, and the flexible display 103 can be taken out by rotating the motor under the control of the control unit 105. [ As the motor rotates, the flexible display 103 can be rolled or unwound and can be pulled out of the body 110.

The sensing unit 107 can sense the drawing and / or drawing amount of the flexible display 103. The sensing unit 107 may include an optical sensor, a gyro sensor, a proximity sensor, and an encoder. The optical sensor may be a barcode sensor, and the barcode printed on the flexible display 103 may be recognized to detect the drawing and drawing amount of the flexible display 103. In addition, the optical sensor can recognize the drawing and / or drawing amount of the flexible display 103 by recognizing the color pattern or the monochrome pattern printed on the flexible display 103.

The gyro sensor may be mounted on the flexible display 103, and the signal outputted from the gyro sensor may be changed according to the drawing amount of the flexible display 103.

The encoder can output an electric signal based on the number of revolutions of the motor. The amount of drawing out is changed in accordance with the number of revolutions of the motor, and the drawing amount of the flexible display 103 can be measured from the signal output from the encoder.

The control unit 105 controls operation of the entire electronic device 100 and can determine the drawing amount of the flexible display 103 based on a signal output from the sensing unit 107. A method of determining the drawing amount of the flexible display 103 will be described later with reference to Figs. 16 to 20. Fig.

The control unit 105 can control to scroll the content displayed in the display area of the flexible display 103 in the direction opposite to the drawing direction of the flexible display 103 based on the drawing amount of the flexible display 103. [

The size of the display area of the flexible display 103 is changed as the flexible display 103 is taken out. The control unit 105 can measure the drawing amount and the drawing speed of the flexible display 103 based on the signal output from the sensing unit 107. [ The control unit 105 can scroll the content displayed on the flexible display 103 in the direction opposite to the drawing direction of the flexible display 103 based on the amount by which the flexible display 103 is drawn out and the drawing speed. For example, when the flexible display 103 is pulled out in the lower direction, the control unit 105 can scroll the content displayed on the flexible display 103 to the upper direction opposite to the pull-out direction of the flexible display 103 . At this time, the scroll speed of the content may be proportional to the draw speed of the flexible display 103. For example, when the drawing speed of the flexible display 103 is 0.5 m / sec, the scroll speed of the content may be 0.5 m / sec.

That is, the control unit 105 measures the speed at which the flexible display 103 is taken out, and controls the content displayed in the display area. The control unit 105 may calculate the number of pixels to be moved in the display area in accordance with the refresh rate and move the position of the screen layout in the direction opposite to the direction in which the flexible display 103 is extended.

2 is a flowchart illustrating a content display method according to the drawing of the flexible display 103 of the electronic device 100 according to an embodiment of the present invention.

When the electronic device 100 is powered on, the control unit 105 senses the initial position of the flexible display 103. The flexible display 103 may be completely wound into the main body 100 of the electronic device 100 and may not have an area exposed to the outside. Alternatively, the flexible display 103 may be partially exposed to the outside of the main body 110 of the electronic device 100. The control unit 105 detects the drawing of the flexible display 103 based on the signal output from the sensing unit 107 (step S201). The control unit 105 determines the drawing amount and the drawing direction of the flexible display 103 based on the signal output from the sensing unit 107. (Step S203) When the power is turned on, In order to determine the amount of drawing, the control unit 105 may receive the signal output from the sensing unit 107 and determine an initial drawing amount. The control unit 105 may analyze the pattern information scanned by the sensing unit 107 and determine the drawing amount of the flexible display 103 when the pattern for sensing the drawing amount is printed on the flexible display 103. [ For example, when the electronic device 100 is powered on while the flexible display 103 is pulled out 20 cm from the main body 100 before the power of the electronic device 100 is turned on, the control unit 105 It is possible to receive information on the pattern of the flexible display 103 output from the sensing unit 107 and determine that the current drawing amount of the flexible display 103 is 20 cm.

The control unit 105 determines the drawing amount of the flexible display 103 and determines the size of the display area according to the drawing amount. When the size of the display area is determined, the controller 105 displays the content on the flexible display 103 in consideration of the area of the flexible display 103 (step S205). For example, when the total size of the flexible display 103 is 55 The control unit 105 controls the flexible display 103 so that the content corresponding to 20 cm from the top of the entire contents is displayed on the screen when the length of the current flexible display is 20 cm in length can do.

The control unit 105 controls the driving unit 103 to take out the flexible display 103. The control unit 105 can sense the drawing speed and direction of the flexible display 103 based on the signal output from the sensing unit 107. For example, the control unit 105 can measure the number of revolutions of the motor from the signal output from the encoder, and determine the drawing speed, direction, and drawing amount of the flexible display 103.

As the flexible display 103 is drawn out, the drawing amount can be continuously changed, and accordingly, the size of the display area can also be continuously changed. The control unit 105 determines the drawing speed, drawing direction, and drawing amount of the flexible display 103 based on the signal output from the sensing unit 107 and determines the drawing speed, drawing direction and drawing amount of the flexible display 103 It is possible to scroll the content displayed on the flexible display 103 in a direction opposite to the drawing direction of the flexible display 103. (Step S207) For example, when the flexible display 103 is moved at a speed of 0.5 m / sec The control unit 105 can scroll the content displayed on the flexible display 103 in the upper direction at a speed of 0.5 m / sec.

The control unit 105 can determine the drawing speed of the flexible display 103 based on the signal output from the sensing unit 107 and determine the scroll speed of the content based on the determined drawing speed.

When the withdrawal amount is determined, the control unit 105 can determine the scroll amount of the content based on the withdrawal amount. The content has attributes, and the control unit 105 can determine whether to display the content on the flexible display 103 from the top or the bottom according to the attribute of the content.

When the amount of drawing increases as the flexible display 103 is drawn out and the amount of drawing matches the threshold value, the control unit 105 can provide feedback corresponding to the threshold value.

The threshold value includes a first value and a second value, and the control unit 105 provides feedback corresponding to the first value when the drawing amount exceeds the first value, and provides feedback corresponding to the second value when the drawing amount exceeds the second value. 0.0 > a < / RTI > value.

Here, the feedback is visual feedback, and the control unit 105 displays the line corresponding to the first value on the flexible display 103 when the display area of the flexible display 103 is expanded to reach the first value, The controller can control the flexible display 103 to display on the flexible display 103 a line corresponding to the second value.

For example, when the area of the flexible display 103 is expanded so that the width-to-length ratio of the display area coincides with the value of the horizontal length of 4: 3, the control unit 105 displays the line corresponding to 4: The flexible display 103 can be controlled so as to display the display data. If the area of the flexible display 103 continues to expand so that the width-to-length ratio of the display area coincides with the value of the width of 16: 9, the control unit 105 displays a line corresponding to 16: 9 in the display area It is possible to control the flexible display 103 to display it.

When the flexible display 103 is wound, the control unit 105 senses the winding of the flexible display 103. The control unit 105 may sense the winding of the flexible display 103 based on the signal output from the sensing unit 107. When the flexible display 103 is wound and enters the main body 110, the control unit 105 can scroll the content displayed on the flexible display 103 in a direction opposite to the direction in which the flexible display 103 is wound. The control unit 105 may control the flexible display 103 to display a black screen in an area where the flexible display 103 is wound and not exposed to the outside. In addition, the control unit 105 can control the flexible display 103 to turn off a region of the flexible display 103 that is not exposed to the outside.

3 is a diagram illustrating a process of displaying content on a screen according to a drawing amount of a flexible display of an electronic device according to an embodiment of the present invention.

Referring to Fig. 3, a main body 301 and a flexible display 303 are shown. According to the drawing amount of the flexible display 303, the sizes 311, 313 and 315 of the contents displayed on the flexible display can be changed. The flexible display 303 is not exposed to the outside of the main body 301 and the state 321 in which the flexible display 303 is drawn out to the outside of the main body 301 by about 30 cm, And a state 325 in which the flexible display 303 is drawn out by about 70 cm from the main body 301 and a state 325 in which the flexible display 303 is drawn out from the main body 301 by about 105 cm. If the flexible display 303 is fully exposed, the length of the display area may be 105 cm. The length of the display area of the flexible display 303 may be less than or equal to the drawing length of the flexible display 303.

When the power is turned on, the flexible display 303 is drawn out of the main body 301, thereby exposing the display area to the outside and expanding the display area. As the display area is expanded, the sizes (311, 313, and 315) of the contents displayed in the display area can be changed.

For example, if the size of the entire display area is 85 inches (105 cm in length), the vertical length of the content displayed in the display area may be 105 cm.

When the power is turned on and the flexible display 303 is started to be pulled out by the rotation of the motor, the display area is expanded and accordingly the size of the content displayed in the display area can also be changed. As the flexible display 303 is drawn out in the lower direction 331, the content displayed in the display area is moved upward in the direction opposite to the drawing direction of the flexible display 303 It can be scrolled.

For example, in the case where the flexible display 303 is pulled out by about 30 cm in the lower direction (321), the content 311 having the size of 30 cm in height can be displayed in the display area. At this time, the content 311 may be displayed in the display area of 30 cm from the top of the entire content in the vertical direction.

 When the flexible display 303 is pulled out approximately 70 cm in the lower direction (323), the content is scrolled in the upper direction, and the content 313 having the size of 70 cm in height can be displayed in the display area. At this time, in the content 313, 70 cm from the top to the top in the entire content can be displayed in the display area.

When the flexible display 303 is drawn out approximately 105 cm in the lower direction (325), the content is scrolled in the upper direction and the content 315 having the size of 105 cm in height can be displayed in the display area. At this time, in the content 315, 105 cm from the top to the top in the vertical direction can be displayed in the display area.

Although the flexible display is drawn out from the main body and the display area is enlarged, the moving speed of the flexible display or the scrolling speed of the display area and the scrolling speed of the content must match in order for the content displayed in the display area to appear natural. That is, the fetching speed of the flexible display and the moving speed of the content displayed in the display area must match.

There are 13.5 pixels per 1 cm based on the vertical length. When the drawing speed of the flexible display is 1 m / sec and the number of frames of content displayed per second is 120, the content must be shifted by about 11 pixels every time one frame is displayed. That is, the content displayed in the display area should be shifted approximately 11 pixels in the upper direction every 0.0083 seconds. In addition, when the time required to take out the flexible display is 1 second and the number of frames of content displayed per second is 120, the content must be moved upward by 9 pixels every time one frame is displayed. That is, the content displayed in the display area must be shifted by 9 pixels in the upper direction every 0.0083 seconds. At this time, the drawing speed of the flexible display is 0.8 m / sec.

There are 23.22580645 pixels per 1 cm based on the vertical length. If the drawing speed of the flexible display is 1 m / sec and the number of frames of content displayed per second is 120, the content should be shifted by about 19 pixels every time one frame is displayed. That is, the content displayed in the display area has to be shifted upward by about 19 pixels every 0.0083 seconds. Also, when the time required to take out the flexible display is 1 second and the number of frames of content displayed per second is 120, the content must be shifted by 18 pixels every time one frame is displayed. That is, the content displayed in the display area must be shifted by 18 pixels in the upper direction every 0.0083 seconds. At this time, the drawing speed of the flexible display is 0.93 m / sec.

When the size of the flexible display is 85 inches, the number of horizontal pixels is 3840, the number of vertical pixels is 2160, the diagonal length is 214 cm, and the vertical length is 105 cm.

The oblique line pattern 1611 can change the position at which the pattern is sensed according to the drawing amount of the flexible display 1603. The control unit 1105 can determine the amount of the flexible display 1603 to be drawn based on the position at which the pattern 1610 is sensed.

The pattern 1613 may be a QR code, a bar code, or a marking type distinguishable from each other, and may be printed in a pattern of a different type for each pixel line. The control unit 1105 can determine the drawing amount of the flexible display 1603 by analyzing the QR code signal output from the sensing unit 1605.

The pattern 1615 is a color pattern and color patterns of different colors may be printed at positions corresponding to the pixel lines. The control unit 1105 may analyze the color signal output from the sensing unit 1605 and determine the drawing amount of the flexible display 1603.

FIGS. 17A and 17B are views showing examples of sensing the amount of drawing out of the flexible display 1717 using a gyro sensor.

17A, a main body 1701 and a flexible display 1717 are shown. The pull-out direction of the flexible display 1717 is the lower end direction 1643.

Flexible display drawing guides 1713 and 1711 and gyro sensors 1703 and 1705 can be installed on the back surface of the flexible display 1717. The gyro sensor 1703 may be installed in the draw-out guide 1711. The gyro sensor 1705 can be installed in the draw-out guide 1713.

The flexible display 1717 is fully extended out of the main body 1701 and the angle 1715 formed by the drawing guide 1713 and the drawing guide 1711 can be maximized. At this time, the difference between the data value of the gyro sensor 1705 and the data value of the gyro sensor 1703 can be the maximum. The control unit 1105 can determine that the flexible display 1717 is completely drawn out of the main body 1701 when the difference between the data values of the two gyro sensors 1705 and 1703 becomes the maximum.

17B, the flexible display 1727 is slightly pulled out of the main body. At this time, the angle 1723 made by the two guides is smaller than the angle 1725 made by the two guides when the flexible display 1717 is completely drawn out. Further, the difference in the data values of the two gyro sensors 1705 and 1703 is relatively small when the flexible display 1717 is completely drawn out.

That is, the control unit 1105 can determine the drawing amount of the flexible display 1727 from the difference between the data values of the two gyro sensors 1705 and 1703. Further, the control unit 1105 can determine whether the flexible display 1727 is being drawn out or winding from the variation amount of the difference between the data values of the two gyro sensors 1705 and 1703. Further, the control unit 1105 can determine the drawing speed of the flexible display 1727 or the winding speed of the flexible display 1727 from the variation amount of the difference between the data values of the two gyro sensors 1705 and 1703.

18A and 18B are views showing examples of sensing the amount of drawing out of the flexible display using the gyro sensor and the proximity sensor. Particularly, a sectional view of the main body.

18A, a main body 1801, a flexible display 1803, a gyro sensor 1805, and a proximity sensor 1807 are shown. A flexible display 1803 is wound in the main body 1801. The flexible display 1803 may be wound into the main body 1801 while being rotated or drawn out of the main body 1801. A gyro sensor 1805 may be installed on the rotation axis of the flexible display 1803.

The gyro sensor 1805 can be rotated as the flexible display 1803 is drawn or spun. The signal output from the gyro sensor 1805 changes as the gyro sensor 1805 rotates and the control unit 1105 changes the signal output from the gyro sensor 1805 based on the signal output from the gyro sensor 1805, Can detect that.

Proximity sensor 1807 may sense the proximity of flexible display 1803. The proximity of the flexible display 1803 when the flexible display 1803 is completely drawn is different from the proximity of the flexible display 1803 when the flexible display 1803 is completely wound and accordingly the output value of the proximity sensor 1807 can be changed. That is, since the output value of the proximity sensor 1807 is changed according to the drawing degree of the flexible display 1803, the control unit 1105 can determine the drawing amount of the flexible display 1803 based on the output signal of the proximity sensor 1807 have.

19 is a diagram showing an example of sensing a drawing amount of the flexible display 1903 using a variable resistor.

19, a main body 1901, a flexible display 1903, a resistance adjusting unit 1905, and a variable resistor 1907 are illustrated. The variable resistor 1907 may be located in the flexible display 1903. [ The resistance value of the resistance adjusting unit 1905 is changed according to the drawing amount of the flexible display 1903 and the control unit 1105 determines the drawing amount of the flexible display 1903 through the difference in the current value flowing to the resistance adjusting unit 1905 .

20 is a diagram showing another example of sensing the amount of drawing out of the flexible display 2003 using a variable resistor.

Referring to FIG. 20, a main body 2001 and a flexible display 2003 are shown. Inside the main body 2001, a flexible display 2003 is wound. The flexible display 2003 can be wound into the main body 2001 or taken out of the main body 2001 while rotating. A variable resistor 2005 may be installed on the rotary shaft of the flexible display 2003. In the variable resistor 2005, the resistance value is changed in accordance with the amount of rotation. When the flexible display 2003 is taken out of the main body 2001 or wound into the main body 2001, the variable resistor 2005 installed on the rotary shaft of the flexible display 2003 rotates and the resistance value can be changed. The value of the current passing through the variable resistor 2005 can be changed as the resistance value is changed and the control unit 1105 determines the amount of drawing out of the flexible display 2003 according to the value of the current passing through the variable resistor 2005 . In other words, the control unit 1105 can determine the drawing amount of the flexible display 2003 based on the signal output from the variable resistor 2005.
