As used herein, the terms " comprises, " and / or "comprising" refer to the presence or absence of one or more other components, steps, operations, and / Or additions. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates a display unit in a display device according to an embodiment of the present invention.

The display device according to an embodiment of the present invention includes a display unit, a connection unit, and a power control unit. And it is connected with the main body part, such as a portable information communication device or a tablet PC.

1 illustrates the display unit, which includes a first display panel 100 and a second display panel 110. Therefore, two display panels having different characteristics are located on both sides of the display unit. The user can use the display panel suitable for the purpose by using the first display panel 100 or the second display panel 110 according to the purpose of use.

For example, the first display panel 100 uses a light emitting display panel that emits itself, such as an LCD, an LED, or an OLED, and the second display panel 110 is itself such as an electronic paper display (eg, an E-ink). The display unit may be configured by using a non-light emitting display panel that does not emit light.

In this case, the first display panel 100, which is a light emitting display panel, is used for general purposes because it has a fast operation speed and can reproduce various colors. In addition, since the second display panel 110, which is a non-light emitting display panel, has characteristics of reducing eye fatigue and reducing power consumption, when reading an e-book or when the power of the device is insufficient. Used for

Therefore, by using both panels according to the use, the user's convenience can be attained and power waste can be prevented. However, in order for the display unit to be mounted and used in the device, a method of switching both panels is required, and various embodiments of the panel switching method are illustrated in FIGS. 2 to 5.

FIG. 2 illustrates a method of connecting the connection unit 220 to a center portion of the side surface of the display unit 200 and switching the display panel by rotating the display unit 200.

The connection part 220 is connected to the center part of the display part 200 and the end part of the main body part 210. In order to change the panel of the display unit 200, the locking device of the display unit 200 is released, the display unit 200 is separated from the main body unit 210, and the display unit 200 is rotated. After the rotation, the display unit 200 is mounted on the main body 210 again and fixed by the locking device, so that the panel being used can be switched to a panel having different characteristics.

3 illustrates a method of switching the display panel by rotating the display unit 300 about a rotation axis attached to one side of the display unit 300.

The connection part 320 is attached to one side of the display part 300, and the connection part 320 connects the display part 300 to the main body part 310 through a rotatable hinge part. In order to switch the display panel, the display panel may be switched by releasing the locking device 330, removing the display unit 300, and then rotating the display unit 300 by 180 degrees about the rotation axis. After the rotation, the display unit 300 is fixed by the locking device 330.

4 illustrates a method of switching a panel of the display unit 400 using a guide rail.

Guide rails are positioned on both sides of the inner side of the main body 410. If the panel of the display unit 400 is to be switched, the lock unit 430 is released to separate the display unit 400, and then the display unit 400 is rotated with the end of the main body unit 410 as an axis. Let's do it.

While the display unit 400 is rotated and the panel is switched and forms the same surface as the main body 410, the display unit 400 is pushed along the guide rails located inside the main body 410. Let the transition take place. After the display unit 400 is pushed in, it is fixed by the locking device 430.

In this state, when the display unit 400 is to be changed to another panel, the locking device 430 is released, the display unit 400 is pulled out along the guide rail, and then the main body 410 of the main body 410 is removed. The panel of the display unit 400 is switched by rotating the display unit 400 with the end as the axis.

5 illustrates a dual display device including a protective plate.

The protection plate 540 is attached to any one side of the display unit 500, and the protection plate 540 moves to cover any one panel of both panels of the display unit 500. That is, the protective plate 540 is used to cover the unused panel and to separate the unused panel and to protect the unused panel. In this case, the connection part 520 may be configured in the shape of a ring binder, and the main body part 510 may be located between both display panels.

As illustrated in FIGS. 2 to 5, when using any one of two display panels included in the display unit, a power control unit may be included to prevent waste of power. The power control unit checks the panel being used and the panel not being used, and ensures that power is supplied only to the panel being used.

The method for identifying the panel in use may include a switch, an optical sensor, a gravity sensor, or a method using an executed application.

The switch is the most basic method. By directly operating the switch, the switch transmits information about the panel being used and the panel not being used to the power control unit so that power is supplied only to the panel being used. In this case, as shown in FIG. 2, two switches or sensors are positioned on both sides of the display unit 200 with respect to the center, and the switch or sensor which contacts the connection unit 220 is identified and used. A method of checking may be used.

The light sensor is located at the front of the panel, and the light quantity can be measured to recognize the panel in use. This is because the panel that is not in use is mounted on the main body and receives no light. Therefore, it recognizes that the panel receiving a lot of light is in use and transmits information about the panel being used as a power control unit.

The gravity sensor detects the direction of gravity, distinguishes the panels located on the top and bottom, and supplies power only to the panels located on the top.

The method using an application is a method of switching panels according to the type of application running on a device, and is a method of supplying power to a panel suitable for the application being used. That is, it checks the information of the application running on the device and supplies power to the panel to be used according to the type of application.

For example, running a typical application while using a light emitting display panel maintains power supply to the light emitting display panel. In addition, when the e-book application is executed while the light emitting display panel is used, a non-light emitting display panel such as an electronic paper display is suitable for the e-book, and thus, power is supplied to the light emitting display panel and the power is supplied to the non-light emitting display panel. And let the panel switch automatically.

In addition, in conjunction with the power management program, when the remaining power of the light emitting display panel becomes less than or equal to a predetermined value, the use of the light emitting display panel may be terminated, and the display may be switched to a non-light emitting display panel with low power consumption.

When the protective plate is included as shown in FIG. 5, the position of the protective plate may be sensed and power may be supplied only to the panel in a direction in which the protective plate is not detected.

In some cases, since both panels may be used, when the master switch is provided and the master switch is in an ON state, power may be supplied to both panels.

6 is a flowchart illustrating a process of providing a dual display according to an embodiment of the present invention.

In order to switch between two display panels having different characteristics, the locking device of the display unit is released (S600). Then, the panel being used is separated from the device and rotated to switch to the display panel located on the opposite side (S620).

At the same time as the panel is switched, only power to the panel to be used and not to the panel that is not used to supply power only to the panel in use (S640).

Finally, the locking device of the display unit is operated again so that the user can use the apparatus through the switched panel while the display unit is fixed to the apparatus (S660).

The foregoing description is merely illustrative of the technical idea of the present invention and various changes and modifications may be made without departing from the essential characteristics of the present invention. Therefore, the embodiments described in the present invention are not intended to limit the scope of the present invention, but are intended to be illustrative, and the scope of the present invention is not limited by these embodiments. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents, which fall within the scope of the present invention as claimed.
