Embodiments of the disclosure will now be described with reference to accompanying drawings.

<FIG> is a perspective view of a display apparatus, according to an embodiment of the disclosure, where a mobile device is held by a holding device.

Referring to <FIG>, a display apparatus <NUM> includes a display module <NUM>, a supporting device <NUM> coupled to the rear of the display module <NUM> for supporting the display module <NUM>, and a holding device <NUM> coupled to the display module <NUM> to hold a mobile device <NUM>.

The display module <NUM> may be a device for displaying information, materials, data, etc., in characters, figures, graphs, images, etc., and may include a television, a monitor, etc..

The display module <NUM> may be configured to display a screen <NUM>. The display module <NUM> may include an actively light-emitting display panel (not shown) such as Organic Light Emitting Diodes (OLEDs) or a passively light-emitting display panel (not shown) such as Liquid Crystal Displays (LCDs). There are no particular limitations on the type of display panel.

The display module <NUM> may be provided to have different vertical and horizontal lengths. That is, the display module <NUM> may have longer sides and shorter sides. The display module <NUM> may be shaped like a rectangular plate.

The supporting device <NUM> may be coupled to the rear of the display module <NUM> for supporting the display module <NUM>. The supporting device <NUM> may include a supporting body <NUM> coupled to the display module <NUM>, and a stand <NUM> coupled to the rear of the supporting body <NUM>. The supporting device <NUM> may stand by itself with the supporting body <NUM> and the stand <NUM> each contacting the ground.

The supporting device <NUM> may include a speaker <NUM> (<FIG>) provided to produce sounds. The speaker <NUM> may be arranged inside the supporting body <NUM>. Specifically, the speaker <NUM> may be arranged in a lower portion within the supporting body <NUM>. The speaker <NUM> may output a sound with an image displayed in the display module <NUM>. Alternatively, the speaker <NUM> may output a sound alone even when the display module <NUM> is powered off. Furthermore, the speaker <NUM> may be wiredly or wirelessly connected to an external device such as the mobile device <NUM> for outputting a song played by the external device.

The holding device <NUM> is provided to hold the mobile device <NUM> to be mounted on the display module <NUM>. The holding device <NUM> may be detachably coupled to the display module <NUM>. The holding device <NUM> may be coupled to or decoupled from the display module <NUM> without any extra member.

The mobile device <NUM> is a kind of external device, including e.g., a smart phone. Mobile devices are widespread these days, and there are attempts to use mobile devices in various ways. Mirroring by which images and sounds presented in the mobile device <NUM> are output through the display module <NUM> or casting by which only content output from a particular application of the mobile device <NUM> is output through the display module <NUM>, are typical examples. To utilize such mirroring or casting, the mobile device <NUM> and the display apparatus <NUM> need to be paired first. According to the disclosure, the mobile device <NUM> and the display apparatus <NUM> may be paired using various methods, which will be described later.

More and more people create contents by taking selfies with cameras these days. It is also more common for people to check their own motions with their cameras when they practice dancing or doing exercises. As such, there are growing needs of users for a mirror mode that uses the camera and the display screen like a mirror. To provide the mirror mode, however, a camera needs to be installed in the display apparatus, which causes concern over privacy invasion and security issues. Furthermore, the rising expenses due to the installation of the camera may lower the saleability of the display apparatus.

According to the disclosure, without installing any camera in the display apparatus <NUM>, the display apparatus <NUM> may provide the mirror mode. For this, the display apparatus <NUM> includes the holding device <NUM>. The display apparatus <NUM> may provide the mirror mode by being paired with the mobile device <NUM> equipped with a camera module (not shown) put onto the holding apparatus <NUM>. The mobile device <NUM> commonly includes the camera module, so the display apparatus <NUM> may provide the mirror mode by using the camera module of the mobile device <NUM>. In this way, using a camera module of an external device such as the mobile device <NUM>, the rise in expenses of camera installation in the display apparatus <NUM> may be prevented. Furthermore, the mobile device <NUM> may be used when required by putting the mobile device <NUM> onto the holding device <NUM>, so the privacy invasion or security issues due to the display device <NUM> may also be prevented.

According to the disclosure, the holding device <NUM> may hold the mobile device <NUM> while the mobile device <NUM> is placed outside the display module <NUM>. Furthermore, the holding device <NUM> may hold the mobile device <NUM> not to cover the front or rear surface of the mobile device <NUM>. In other words, when the mobile device <NUM> is put onto the holding device <NUM>, a display, the front of the mobile device <NUM> may not be hidden by the holding device <NUM>. Accordingly, the user may be able to make touch inputs through the display of the mobile device <NUM> while putting the mobile device <NUM> onto the holding device <NUM>. The user may also use a camera module placed on the front of the mobile device <NUM> or a camera module placed on the rear of the mobile device <NUM> while putting the mobile device <NUM> onto the holding device <NUM>.

<FIG> is a front view of a display apparatus, according to an embodiment of the disclosure, where a display module is positioned lengthwise. <FIG> is a front view of a display apparatus, according to an embodiment of the disclosure, where a display module is positioned widthwise.

Referring to <FIG>, the display module <NUM> may have the longer sides positioned lengthwise and the shorter sides positioned widthwise. This positioning of the display module <NUM> is hereinafter called lengthwise mode. It is also said that the display module <NUM> is positioned in a first position.

Referring to <FIG>, the display module <NUM> may have the longer sides positioned widthwise and the shorter sides positioned lengthwise. This positioning of the display module <NUM> is hereinafter called widthwise mode. It is also said that the display module <NUM> is positioned in a second position.

The user may selectively place the display module <NUM> in the lengthwise mode or widthwise mode depending on a screen ratio of an image.

It is common for the conventional display module to be fixed widthwise. In this case, when the conventional display module displays a lengthwise image, either side of the screen is blanked, making it impossible to efficiently use the screen of the display module. The lengthwise image and the widthwise image both tend to be used these days, so there is a need for a display apparatus capable of displaying various screen ratios in efficient ways.

The display apparatus <NUM> allows the display module <NUM> to be positioned in the lengthwise mode to display a lengthwise image and in the widthwise mode to display a widthwise image, thereby efficiently using a screen display region <NUM>. Accordingly, the display apparatus <NUM> in accordance with the disclosure may efficiently present various screen ratios.

In an embodiment of the disclosure, the display apparatus <NUM> includes the display module <NUM> and the supporting device <NUM> for supporting the display module <NUM> to be automatically turned by a motor (not shown).

Referring to <FIG> and <FIG>, the display module <NUM> may be turned from the lengthwise mode into the widthwise mode or vice versa. The supporting device <NUM> may turn the display module <NUM> from the lengthwise mode into the widthwise mode or vice versa.

The supporting device <NUM> includes the motor. The supporting device <NUM> may turn the display module <NUM> by using driving force of the motor. Accordingly, the display module <NUM> may be automatically turned by driving the motor without the need for the user manually turning the display module <NUM>.

According to the disclosure, the holding device <NUM> may hold the mobile device <NUM> even when the display module <NUM> is positioned in the widthwise mode. In other words, the holding device <NUM> may hold the mobile device <NUM> to prevent the mobile device <NUM> from being decoupled from the holding device <NUM> even when the display module <NUM> is positioned in the widthwise mode. Accordingly, regardless of positioning of the display module <NUM>, the mobile device <NUM> may be put onto the display module <NUM>.

The user may selectively position the display module <NUM> in the lengthwise mode or the widthwise mode, and the display apparatus <NUM> may provide mirror mode, mirroring, or casting in each of the lengthwise mode and the widthwise mode.

In an embodiment of the disclosure, when the mobile device <NUM> is put onto the holding device 100a while a widthwise image is reproduced in the mobile device <NUM>, the display module <NUM> may be positioned in the widthwise mode. When the display module <NUM> is already positioned in the widthwise mode, the display module <NUM> may not be turned even when the mobile device <NUM> is put onto the holding device <NUM>. When the mobile device <NUM> that is reproducing a widthwise image is put onto the holding device <NUM> while the display module <NUM> is positioned in the lengthwise mode, the display module <NUM> may be turned into the widthwise mode from the lengthwise mode. This may enable early detection of the user's mirroring or casting intention and increase user convenience.

As shown in <FIG>, the speaker <NUM> may be placed below the display module <NUM>. The speaker <NUM> may be arranged not to be covered by the display module <NUM> even positioned in the lengthwise mode. This enables the speaker <NUM> to output sound stably regardless of the positioning of the display module <NUM>. Furthermore, although the speaker <NUM> is shown as being viewed from outside of the supporting device <NUM>, there may be a metal cover or fabric cover with multiple holes provided in front of the speaker <NUM>.

In an embodiment of the disclosure, the holding device <NUM> included in the display apparatus <NUM> may be detachably mounted onto the display module <NUM>. The holding device <NUM> may be mounted onto or detached from the display module <NUM> without any extra member.

The holding device <NUM> may be mounted on a flank of the display module <NUM> when the display module <NUM> is positioned lengthwise. The holding device <NUM> may be mounted on an upper portion of a flank of the display module <NUM> not to interfere with the supporting device <NUM> when the display module <NUM> is turning into the widthwise mode from the lengthwise mode.

Furthermore, unlike what is shown in the drawings, the holding device <NUM> may be mounted on a flank of the display module <NUM> when the display module <NUM> is positioned widthwise. In other words, when the display module <NUM> is positioned lengthwise, the holding device <NUM> may be mounted on the top of the display module <NUM>.

It is desirable for the holding device <NUM> to be above the top of the supporting device <NUM> when the display module <NUM> is positioned lengthwise, but it is not limited thereto. Even when the holding device <NUM> is mounted onto the display module <NUM>, it may not interfere with turning of the display module <NUM>. When the holding device <NUM> is provided to be accommodated in a space formed between the rear surface of the display module <NUM> and the front surface of the supporting device <NUM>, the mounting position of the holding device <NUM> is not limited. In this case, the holding device <NUM> may be freely mounted at any location along the edges of the display module <NUM>.

<FIG> shows a holding device of a display apparatus. <FIG> shows a second supporter drawn out from the holding device shown in <FIG>.

Referring to <FIG>, the holding device <NUM> includes a mounting part <NUM> that may be mounted on a frame <NUM> (see <FIG>) of the display module <NUM>, and a holder <NUM> rotatably coupled to the mounting part <NUM> and provided to hold the mobile device <NUM>. The frame <NUM> is provided to form edges of the display module <NUM>.

The frame <NUM> includes a front surface 15a, a side surface 15b, and a rear surface 15c (see <FIG>). The front surface 15a of the frame <NUM> is provided to come into contact with the screen display region <NUM>. The front surface 15a of the frame <NUM> protrudes forward from the screen display region <NUM> and incline outward from the screen display region <NUM>. The side surface 15b of the frame <NUM> is linked to the front surface 15a of the frame <NUM> and may incline rearward from the screen display region <NUM>. The side surface 15b of the frame <NUM> is larger than the front surface 15a of the frame <NUM>. The rear surface 15c of the frame <NUM> may extend from the side surface 15b of the frame <NUM> toward the rear side of the display module <NUM>.

The mounting part <NUM> may be provided to be mounted onto the frame <NUM> of the display module <NUM>. The mounting part <NUM> may be mounted onto the display module <NUM> without any extra member, and detached from the display module <NUM> without any extra member.

The mounting part <NUM> may include a mounting groove 110a shaped to correspond to the cross-section of the frame <NUM> of the display module <NUM>, and an elastic groove 110b formed at a distance from the rear side of the display module <NUM>. Furthermore, the mounting part <NUM> includes a front supporter <NUM> to support the front of the frame <NUM>, a side supporter <NUM> to support the flank of the frame <NUM>, a rear supporter <NUM> to support the rear side of the display module <NUM>, and an elastic connector <NUM> to connect the side supporter <NUM> and the rear supporter <NUM>.

The mounting groove 110a may be defined by the front supporter <NUM>, the side supporter <NUM>, and a portion of the elastic connector <NUM>. The elastic groove 110b may be defined by the rear supporter <NUM> and the rest of the elastic connector <NUM>.

The front supporter <NUM> may correspond to the front surface of the frame <NUM> to support the front surface of the frame <NUM>. The side supporter <NUM> may correspond to the side surface of the frame <NUM> to support the side surface of the frame <NUM>. The rear supporter <NUM> comes into contact with a portion of the rear side of the display module <NUM> to support the rear side of the display module <NUM>.

The elastic connector <NUM> is provided to connect the side supporter <NUM> to the rear supporter <NUM>. The elastic connector <NUM> may have a curved cross-section. Specifically, the elastic connector <NUM> may have a swollen form toward the rear side of the display module <NUM>. The elastic connector <NUM> may have substantially constant thickness. With the constant thickness and curved form of the elastic connector <NUM>, the elastic groove 110b may be formed between the rear side of the display module <NUM> and the elastic connector <NUM>. While the front supporter <NUM> and the side supporter <NUM> may come into contact with the front and flank of the frame <NUM>, the elastic connector <NUM> may not contact the frame <NUM> or the display module <NUM>.

With the curved form, the elastic connector <NUM> may not be broken even when the rear supporter <NUM> is moved a certain distance in a direction away from the rear side of the display module <NUM>. Due to the curved form, elastic limits of the elastic connector <NUM> may increase. With the increase in the elastic limits of the elastic connector <NUM>, the distance for the rear supporter <NUM> to be moved backwards from the display module <NUM> may increase.

When the holding device <NUM> is to be mounted onto or detached from the display module <NUM>, the rear supporter <NUM> needs to be moved back, in which case due to the curved form of the elastic connector <NUM>, the elastic limits of the elastic connector <NUM> may increase and the distance for the rear supporter <NUM> to be moved backwards may increase accordingly. Furthermore, the elastic connector <NUM> may secure the holding device <NUM> to the display module <NUM> by applying tension for the rear supporter <NUM> to be moved forwards even after the holding device <NUM> is mounted onto the display module <NUM>. Hence, the holding device <NUM> may secure the display module <NUM> to the holding device <NUM> with restoring force of the elastic connector <NUM> to restore to its original state after the elastic connector <NUM> is elastically deformed.

The holder <NUM> may support the mobile device <NUM> to prevent the mobile device <NUM> from being decoupled from the holding device <NUM>.

Referring to <FIG>, the holder <NUM> may include a first supporter <NUM> provided to support a side of the mobile device <NUM> and a second supporter <NUM> provided to support the other side of the mobile device <NUM>. The first supporter <NUM> may be coupled to the mounting part <NUM>. The second supporter <NUM> may slidingly move with respect to the first supporter <NUM>. The second supporter <NUM> may be able to slide within a certain range in a direction away from the first supporter <NUM>. Hereinafter, the second supporter <NUM> sliding in the direction away from the first supporter <NUM> may be expressed as the second supporter <NUM> being drawn out.

As shown in <FIG>, the first and second supporters <NUM> and <NUM> may be provided to come into contact with each other. As will be described later, with no external force applied, the first and second supporters <NUM> may contact each other or may be located closest to each other due to elastic force of an elastic member. When the first and second supporters <NUM> and <NUM> are located closest to each other, the distance between the first and second supporters <NUM> and <NUM> may be set to be less than the left-to-right length of the mobile device <NUM>.

As shown in <FIG>, with external force applied, the second supporter <NUM> may move away from the first supporter <NUM>. When the first and second supporters <NUM> and <NUM> are located farthest from each other, the distance between the first and second supporters <NUM> and <NUM> may be set to be greater than common left-to-right length of the mobile device <NUM>.

The user may move the second supporter <NUM> such that the distance between the first and second supporters <NUM> and <NUM> becomes wider, and then place the mobile device <NUM> between the first and second supporters <NUM> and <NUM>. When the force to the second supporter <NUM> is released after the mobile device is placed between the first and second supporters <NUM> and <NUM>, the second supporter <NUM> may move to the first supporter <NUM> due to elastic force and the mobile device <NUM> may be supported by the first and second supporters <NUM> and <NUM>. Structures of the first and second supporters <NUM> and <NUM> will be described later in detail.

In this example, the second supporter <NUM> may be drawn in the first supporter <NUM>, as shown in <FIG>. When the second supporter <NUM> is drawn in the first supporter <NUM>, the distance between the first and second supporters <NUM> and <NUM> may be a minimum distance.

As shown in <FIG>, the second supporter <NUM> may be drawn out from the first supporter <NUM> by external force. The second supporter <NUM> may be moved in a direction of being drawn in the first supporter <NUM> by elastic force of the elastic member. With the elastic force of the elastic member, the mobile device <NUM> may be held between the first and second supporters <NUM> and <NUM>.

<FIG> shows the holding device shown in <FIG> with a holder turning round.

Referring to <FIG>, in the holding device <NUM>, a holder <NUM> may be rotatably coupled to a holder supporter <NUM> of the mounting part <NUM>. The holder supporter <NUM> may be formed by extending laterally from the mounting part <NUM>. The holder <NUM> may be coupled to the holder supporter <NUM> by ball joint. Accordingly, the holder <NUM> may be freely turned against the holder supporter <NUM>. In other words, the rotation axis of the holder <NUM> may not be fixed. The holder <NUM> may be provided to freely turn on any rotation axis.

<FIG> is an exploded view of a holding device in a display apparatus, for context. <FIG> shows the holding device of <FIG> viewed at a different angle.

For context, a detailed structure of another holding device will now be described in connection with <FIG> and <FIG>.

Referring to <FIG> and <FIG>, the holding device <NUM> includes the mounting part <NUM> which may include the holder supporter <NUM>, the first supporter <NUM>, an elastic member supporter <NUM> coupled to an inner portion of the first supporter <NUM> and coupled to an end <NUM> of a second elastic member <NUM>, and the second supporter <NUM> coupled to the other end <NUM> of the second elastic member <NUM>.

In addition, the holding device <NUM> may include a ball joint part 221a, <NUM>, and <NUM> to freely rotatably couple the holder <NUM> to the holder supporter <NUM>.

The ball joint part 221a, <NUM>, and <NUM> may include a ball housing 221a arranged on the holder supporter <NUM>, a ball <NUM> inserted to the ball housing 221a, and a ball fixing member <NUM> coupled to the ball housing 221a to fix a position of the ball <NUM>.

The holder <NUM> may be coupled to the holder supporter <NUM> via ball joint.

Specifically, the ball <NUM> may be inserted to the ball housing 221a formed on the rear surface of the first supporter <NUM>. The ball housing 221a may receive the ball <NUM> inside, and screw threads may be formed on the outer surface of the ball housing <NUM>. Alternatively, the ball housing 221a may be provided to accommodate the ball <NUM> inside multiple projections with screw threads.

The ball fixing member <NUM> may include an inner surface having screw threads. Furthermore, the ball fixing member <NUM> may include a through hole <NUM> for a fastening member S4 to pass through. Moreover, the ball fixing member <NUM> may include a jagged portion <NUM> to produce frictional force when the user turns the ball fixing member <NUM>. The jagged portion <NUM> is one of various forms to produce frictional force, and may employ any other form to produce frictional force.

The holder <NUM> may be freely turned until the ball fixing member <NUM> is coupled to the ball housing 221a by being screwed to the ball housing 221a. The user may screw the ball fixing member <NUM> to the ball housing 221a to fix the holder at a desired angle. Once the ball fixing member <NUM> is coupled to the ball housing 221a by being screwed to the ball housing 221a, a position of the holder <NUM> may be fixed. In order for the holder <NUM> to be fixed to the holder supporter <NUM>, the fastening member S4 may be fastened to a first fastener 215a formed on the rear of the holder supporter <NUM> and a second fastener <NUM> provided at the ball <NUM>. This enables the holder <NUM> to be coupled to the holder supporter <NUM>.

Coupling between the first and second supporters <NUM> and <NUM> will now be described.

The first supporter <NUM> may be coupled (ball-jointed) to the holder supporter <NUM> by the ball joint part 221a, <NUM>, and <NUM>, as described above.

The first supporter <NUM> may include a first coupling hole 221b formed to be coupled to the elastic member supporter <NUM>. The elastic member supporter <NUM> may include a second coupling hole <NUM> corresponding to the first coupling hole 221b. After the positions of the first coupling hole 221b and the second coupling hole <NUM> are matched, the elastic member supporter <NUM> may be coupled to the first supporter <NUM> by a fastening member (not shown).

A third elastic member hole <NUM> may be formed at the elastic member supporter <NUM> for the end <NUM> of the second elastic member <NUM> to be inserted thereto. The second supporter <NUM> may include a fourth elastic member hole 222a formed for the other end <NUM> of the second elastic member <NUM> to be inserted thereto. The second elastic member <NUM> may have the one end <NUM> linked to the elastic member supporter <NUM> and the other end linked to the second supporter <NUM>. As the elastic member supporter <NUM> is coupled to the first supporter <NUM>, the second elastic member <NUM> may exert elastic force between the first and second supporters <NUM> and <NUM>. There are no limitations on types of the second elastic member <NUM>, but the second elastic member <NUM> may be a tension spring.

When the second supporter <NUM> is drawn out from the first supporter <NUM>, the second elastic member <NUM> may exert elastic force for the second supporter <NUM> to be moved toward the first supporter <NUM>. This elastic force may enable the mobile device <NUM> to be held between the first and second supporters <NUM> and <NUM>.

The first supporter <NUM> may include a stopper 221c to restrict the movement range of the second supporter <NUM>. The second supporter <NUM> may include a stopper groove 222b formed for the stopper 221c to be inserted thereto. As the stopper 221c is movable within the stopper groove 222b, the movement range of the second supporter <NUM> is limited.

<FIG> is a cross-sectional view along line B-B of <FIG>.

As shown in <FIG>, the mounting part <NUM> may be formed with a first member defining the front supporter <NUM> and the side supporter <NUM> and a second member defining the rear supporter <NUM> and the elastic connector <NUM>. The first member and the second member may be coupled to each other by a fastening member S3 as shown in <FIG>. It is, however, an example, and in the mounting part <NUM>, the front supporter <NUM>, the side supporter <NUM>, the rear supporter <NUM>, and the elastic connector <NUM> may be integrated in one body.

Furthermore, referring to <FIG>, the fastening member S4, as described above, may be fastened to the second fastener <NUM> of the ball <NUM> by passing through the first fastener 215a and the through hole <NUM> of the ball fixing member <NUM> from behind the holder supporter <NUM>.

The user may freely turn the holder <NUM> or fix the holder <NUM> in a position by turning the ball fixing member <NUM> to adjust coupling power between the ball fixing member <NUM> and the ball housing 221a.

Moreover, the first supporter <NUM> may include the stopper 221c, which may be inserted to the stopper groove 222b of the second supporter <NUM>. The second supporter <NUM> may be drawn out from the first supporter <NUM> until the stopper 221c reaches an end of the stopper groove 222b.
