<FIG> is a perspective view of a display device, according to a first embodiment of the disclosure, and <FIG> is an exploded perspective view of the display device, according to the first embodiment of the disclosure.

While the following description will focus on a flat display device <NUM>, embodiments of the disclosure may be applied to bendable display devices as well. Although a passively light-emitting display will be focused in the following description, it is, of course, possible that embodiments of the disclosure may be applied to an actively light-emitting display.

The terms 'forward' and 'front' are defined with respect to the a display panel <NUM> of the display device <NUM> shown in <FIG>, i.e., the front side of the display panel <NUM> on which an image is displayed. The terms 'top (or upper side)' and 'bottom (or lower side)' indicates top and bottom of the display device <NUM> shown in <FIG>, respectively, and 'both sides' and 'sideways (or laterally)' refer to the horizontal direction of the display device <NUM>.

The display device <NUM> may include a display module for displaying an image.

The display device <NUM> may include a chassis assembly that accommodates and supports the display panel <NUM> and a backlight unit.

The display panel <NUM> may include a liquid crystal panel formed of liquid crystals (not shown) enclosed between two glass panels (not shown) each having an electrode, and display an image on the front.

The chassis assembly may include a top chassis <NUM>, a middle mold <NUM>, and a bottom chassis <NUM>.

The top chassis <NUM> may include an opening 82a to disclose the display panel <NUM>. The bottom chassis <NUM> may include a bottom part 84a arranged under the backlight unit, and a bottom side part 84b extending upward from the bottom part 84a.

Many different components of the display device <NUM>, such as the top chassis <NUM> and the middle mold <NUM> may be supported on the bottom chassis <NUM>.

The bottom chassis <NUM> may serve to radiate heat generated from a light source <NUM> to the outside. Specifically, the heat generated from the light source <NUM> may be conveyed to the bottom chassis <NUM> through a printed circuit board (PCB) <NUM>, and radiated from the bottom chassis <NUM>. For this, the bottom chassis <NUM> may be formed of aluminum, various metals such as SUS, or plastics such as ABS, which has good heat conductivity. Also for the PCB <NUM>, a metal such as aluminum with good heat conductivity may be used.

In another embodiment, however, at least one of the top chassis <NUM>, the middle mold <NUM>, and the bottom chassis <NUM> may be omitted or integrated with another.

The display device <NUM> may further include a rear cover <NUM> for covering the chassis assembly to protect and accommodate the chassis assembly and covering the rear side of the bottom chassis <NUM>.

The display device <NUM> may further include a backlight unit provided to supply light to the display panel <NUM>.

In the embodiment, the backlight unit may be of a direct type in which the light source <NUM> is arranged right beneath the display panel <NUM>. The backlight unit may include a light source module <NUM> that includes the light source <NUM> and the PCB <NUM> with the light source mounted thereon, and various optical sheets <NUM> arranged in a traveling path of light radiated from the light source <NUM>.

The light source <NUM> may be provided to supply light to the display panel <NUM>. The light source <NUM> may include light emitting diodes (LEDs). The LEDs may be provided in a package in which an LED chip is mounted on a substrate and which is filled with resins. Unlike this, in another embodiment, a cold cathode fluorescent lamp (CCFL) or an external electrode fluorescent lamp (EEFL) may be used for the light source.

A plurality of light sources <NUM> may be mounted on the PCB <NUM> at certain intervals. For example, a circuit pattern to convey driving power and signals to the light sources <NUM> may be formed on the PCB <NUM>. The PCB <NUM> may be safely arranged on the bottom chassis <NUM>.

Light output from the light source <NUM> may be directly supplied to the display panel <NUM> unlike in an edge type display device. It is not limited thereto, and the rear cover <NUM>, and a stand member <NUM>, which will be described later, of the display device <NUM> according to the disclosure may also be applied in an edge-type display device.

In this regard, to improve optical characteristics of light output from the light source <NUM>, the optical sheet <NUM> may be arranged between the light source <NUM> and the display panel <NUM>.

The backlight unit may include a diffusion sheet <NUM>. The diffusion sheet <NUM> may cancel or minimize light irradiated from the light source <NUM>. The light irradiated from the light source <NUM> comes directly into human eyes, making the pattern in which the light source <NUM> is arranged visible as it is, and hence the diffusion sheet is used to cancel or minimize this effect.

Typically, the diffusion sheet <NUM> is included in the optical sheet <NUM> as a part of the optical sheet <NUM>. The diffusion sheet <NUM> may be provided to diffuse the light irradiated from the light source module <NUM> to all directions so as to uniformly cast the light in all directions on an image.

The backlight unit may further include a reflector sheet <NUM> for reflecting light to prevent loss of light. The reflector sheet <NUM> may reflect light irradiated from the light source <NUM> to be incident on the diffusion sheet <NUM>. The reflector sheet <NUM> may have various forms, such as a sheet, a film, a plate, etc. For example, the reflector sheet <NUM> may be formed by coating a base material with a highly reflective material. SUS, brass, aluminum, PET, etc., may be used for the base material, and silver, TiO<NUM>, etc., may be used as a highly reflective coating agent. The reflector sheet <NUM> may be safely seated and supported on the PCB <NUM>.

The rear cover <NUM> may cover the edges of the display device <NUM> while covering the rear side of the bottom chassis <NUM> as described above. It is not limited thereto, and the edges of the display device <NUM> may be covered by an additional frame or housing. However, in the following description, it will be assumed that the edges (or frames) of the display device <NUM> are covered by the rear cover <NUM>.

Moreover, a direct-type display device will be taken as an example in describing the following embodiments of the disclosure, but embodiments of the disclosure are not limited thereto, and may also be applied to an edge-type display device.

The display device <NUM> may be installed on the wall (a mount type), or placed on the floor with a stand (a stand-type), depending on needs of the user.

On an occasion when a conventional display device is installed on the wall, a stand that otherwise supports the display device needs to be kept somewhere separately, in which case the stand might happen to be lost.

For example, the user may install the display device in the mount-type or the stand-type for the space, and a problem may arise when the installation of the display device is to be changed from the mount-type to the stand-type and the stand having thus far been kept separately is lost.

To solve this problem, the display device <NUM> according to embodiments of the disclosure may include a stand unit <NUM> (which has a space which can be referred to as stand compartment) that includes a stand <NUM> to support the display device <NUM>. The stand unit <NUM> is coupled with the display device <NUM> to prevent the problem of losing the stand <NUM>.

Specifically, the display device <NUM> may include the stand unit <NUM>, and in a case of installing the display device <NUM> on the wall, the stand <NUM> is pulled into the display device <NUM>, and in a case of placing the display device <NUM> on the floor, the stand <NUM> may be pulled out of the display device <NUM> to support the display device <NUM> from the floor.

There may be two stand units <NUM> and 100R on the left and right of the display device <NUM>. The rear cover <NUM> may include two through holes, one of which is denoted by91, for the stand units <NUM> and 100R to pass through, respectively. The stand units <NUM> and 100R are arranged in the same configuration on the left and right of the display device <NUM>, so for convenience of explanation, one of the stand units <NUM> and 100R will be focused to describe the stand unit <NUM>. Moreover, the stand unit <NUM> is not limited thereto, but may be provided in two or more.

The stand unit <NUM> of the display device <NUM> according to a first embodiment of the disclosure will now be described in detail.

<FIG> shows the stand unit of the display device with the stand member pulled in, according to the first embodiment of the disclosure, <FIG> is a bottom perspective view of the display device with the stand member pulled in, according to the first embodiment of the disclosure, <FIG> shows the stand unit of the display device with the stand member partially pulled out, according to the first embodiment of the disclosure, <FIG> is a bottom perspective view of the display device with the stand member partially pulled out, according to the first embodiment of the disclosure, <FIG> shows the stand unit of the display device with the stand member fully pulled out, according to the first embodiment of the disclosure, and <FIG> is a bottom perspective view of the display device with the stand member fully pulled out, according to the first embodiment of the disclosure.

The stand unit <NUM> may include a rotation guide for rotating at least a portion of the stand <NUM> around a rotation shaft.

The rotation guide may be provided for the stand <NUM> to support the display device <NUM> by being engaged with the movement of the stand <NUM> by its self-weight to rotate at least a portion of the stand <NUM> when the stand <NUM> is pulled out of the display device <NUM>.

In the first to third embodiments as will be described later, the rotation guide is a general term of a collection of all components to rotate the stand <NUM> (e.g., an elastic member, a gas cylinder <NUM>, a transmitter <NUM>, a restricting member <NUM>, a guide projection <NUM>, etc.), and in the following description, names of the components of the rotation guide will be mentioned.

The stand unit <NUM> may be arranged between the bottom chassis <NUM> and the rear cover <NUM> (see <FIG>). For example, the stand unit <NUM> may be arranged between the bottom chassis <NUM> and the rear cover <NUM> in an empty space having no electric parts arranged therein. Furthermore, the stand unit <NUM> may be coupled onto the rear side of the bottom chassis <NUM> or the front side of the rear cover <NUM>.

The stand unit <NUM> may include a case <NUM> that receives or takes out the stand <NUM>, and a housing <NUM> fixed to the case <NUM> for the stand <NUM> to be pulled in or out of case <NUM>.

The stand unit <NUM> may also include a locking device <NUM> to fix the stand <NUM> by locking the stand <NUM> to remain in a state of being received in the case <NUM>.

The locking device <NUM> may be arranged on the top of the stand <NUM>. At least a portion of the stand <NUM> may be put into and constrained by the locking device <NUM>, and accordingly, the stand <NUM> may be locked in the locking device <NUM>.

The stand <NUM> may be locked in the locking device <NUM> while being received in the case <NUM>.

The locking device <NUM> may be provided to unlock the stand <NUM> when the stand <NUM> is pushed up. In other words, the locking device <NUM> may lock or unlock the stand <NUM> based on pushing.

The locking device <NUM> may be provided in the form of a push locking device such as a ratchet. In the first and other embodiments as will be described later, the locking device is assumed to be a ratchet.

When the stand <NUM> is released from the locked state, the stand <NUM> may be moved down by its self-weight. Accordingly, the stand <NUM> may be pulled out of the case <NUM>.

When the stand <NUM>, which has been pulled out, is pushed up, the stand <NUM> is moved up again by the external force, and at least a portion of the stand <NUM> in turn pushes the locking device <NUM> and accordingly, is constrained back in the locking device <NUM>, ending up with the stand <NUM> being pulled back into the case <NUM>.

In this way, the stand <NUM> may be moved up or down, and fixed at a particular position by the locking device <NUM>. Specifically, a highest position to which the stand <NUM> may be moved up may be defined by the locking device <NUM>, and a lowest position to which the stand <NUM> may be moved down may be defined by a stopper <NUM>, which will be described later.

The stand <NUM> may then be moved between the highest position and the lowest position. The stand <NUM> may be vertically moved by a certain distance that is set by the highest and lowest positions.

The case <NUM> may have the form of a box with six faces, and include an opening <NUM> on the bottom side that is opened vertically for the stand <NUM> to be vertically moved through the opening <NUM>.

The opening <NUM> may be formed to be equal to or greater than the cross-sectional area of a supporting portion <NUM> of the stand <NUM> for the supporting portion <NUM> to pass through the opening <NUM>.

A face of the case <NUM> is formed to be openable (see <FIG>), so that the components of the stand unit <NUM> including the stand <NUM> may be safely placed inside the case <NUM>. The case <NUM> is not limited to having the form as in the first embodiment, but may have the form of a quadrangular frame opened to the front and back, in which case the housing <NUM> may be directly coupled onto the rear side of the bottom chassis <NUM> or the front side of the rear cover <NUM>. The case <NUM> still is not limited thereto, but may have any other form.

The housing <NUM> may be provided for the stand <NUM> to pass through. The housing <NUM> may include a movable housing <NUM> and <NUM> engaged with the stand <NUM> to be movable in the vertical direction, and a fixed housing <NUM> fixed to the case <NUM>.

The movable housing <NUM> and <NUM> may be movable against the fixed housing <NUM>, i.e., movable while coupled with the fixed housing <NUM>.

Since the stand <NUM> may be coupled with the movable housing <NUM> and <NUM>, it may be movably coupled with the fixed housing <NUM> through the movable housing <NUM>. Hence, the housing <NUM> may prevent deviation of the stand <NUM> from the case <NUM> while the stand <NUM> is moving.

The movable housing <NUM> and <NUM> may include a stand housing <NUM> through which the stand <NUM> passes, and a combining housing <NUM> with which a gear portion <NUM> or the transmitter <NUM>, which will be described later, may be coupled.

The stand unit <NUM> may include the stopper <NUM> to restrict vertical movement of the stand <NUM> and the movable housing <NUM> and <NUM>. The stopper <NUM> may restrict movements of the stand <NUM> and the movable housing <NUM> and <NUM> so that the stand <NUM> and the movable housing <NUM> and <NUM> may be vertically moved within a certain range.

A contact 132a may be provided in a portion of the movable hosing <NUM> and <NUM> for the movable housing <NUM> and <NUM> to reach the stopper <NUM> when moving down a certain distance. Specifically, the contact 132a may be provided to protrude from a side of the combining housing <NUM> toward a direction in which the stopper <NUM> extends.

Although not shown, the fixed housing <NUM> may include a guide (not shown) for guiding the movement of the stand <NUM> and movable housing <NUM> and <NUM>. The guide may guide the stand <NUM> and the movable housing <NUM> and <NUM> so that the stand <NUM> and the movable housing <NUM> and <NUM> may be moved straight in the vertical direction.

The stand <NUM> may be moved down until the contact 132a contacts the stopper <NUM>, and in the state of contact between the stopper <NUM> and the contact 132a, the stand <NUM> is restricted by the stopper <NUM> from moving down.

The stand <NUM> may include a body portion <NUM>, a locked portion <NUM> arranged on the top of the body portion <NUM> and inserted to and constrained by a locking device <NUM>, and the supporting portion <NUM> provided to be pulled out of the display device <NUM> when the stand <NUM> is unlocked and thus to support the display device <NUM> from the floor.

The stand unit <NUM> includes a gas cylinder <NUM>. The gas cylinder <NUM> may be provided to contract or expand by being engaged with vertical movement of the stand <NUM>.

The gas cylinder <NUM> may transmit force created from the contraction or the expansion to the stand <NUM> for the supporting portion <NUM> to be rotated in a state of being pulled from the display device <NUM>. This will be described in more detail later.

The stand unit <NUM> may include the transmitter <NUM> for transmitting the force created by the gas cylinder <NUM> to the stand <NUM>. The stand unit <NUM> may further include the gear portion <NUM> driven by the transmitter <NUM>.

Specifically, the force created by the gas cylinder <NUM> may rotate the gear portion <NUM> via the transmitter <NUM>.

The stand <NUM> may include a stand gear <NUM> arranged in the body portion <NUM> and is engaged in gear with the gear portion <NUM>. Accordingly, when the gear portion <NUM> is rotated, the stand gear <NUM> may be rotated in gear with the gear portion <NUM>, and hence the body portion <NUM> may be rotated as well.

When the body portion <NUM> is rotated, the supporting portion <NUM> arranged beneath and engaged with the body portion <NUM> is rotated, which will be described later.

A process in which the stand <NUM> is pulled in or out by the stand unit <NUM> will now be described in detail.

As shown in <FIG> and <FIG>, when the display device <NUM> is in a packaged state or installed on the wall in the mount-type, the stand <NUM> may be placed in a pull-in position 110A.

When the stand <NUM> is placed in the pull-in position 110A, the movable housing <NUM> and <NUM> and the transmitter <NUM> engaged with the stand <NUM> may be in positions corresponding to the pull-in position 110A of the stand <NUM>.

The gas cylinder <NUM> is connected to the transmitter <NUM>, and the gas cylinder <NUM> may go into a contraction state 140A as the transmitter <NUM> is in a position corresponding to the highest position of the stand <NUM>.

Specifically, the gas cylinder <NUM> may contract or expand while the gas cylinder is fixed to the case <NUM> and a piston of the gas cylinder <NUM> engaged with the transmitter <NUM> moves vertically.

When the stand <NUM> is placed in the pull-in position 110A, it lies inside the case <NUM> or display device <NUM> and is not exposed.

A through hole <NUM> is arranged on the rear side 90a of the rear cover <NUM> for the stand <NUM> to pass through in the vertical direction. The through hole <NUM> may be formed to be equal to or greater than the cross-sectional area of the supporting portion <NUM> of the stand <NUM> for the supporting portion <NUM> to pass through the through hole <NUM>.

A shape of the through hole <NUM> may match the shape of the supporting portion <NUM>.

When the stand <NUM> is placed in the pull-in position 110A, it is not pulled out of the through hole <NUM> and thus, not exposed, but it is possible for the user to push the stand <NUM> upward through the through hole <NUM> from the outside.

The user may push the stand <NUM> upward to pull the stand <NUM> out of the display device <NUM>.

When the stand <NUM> is pushed up, the locked portion <NUM> inserted to the locking device <NUM> may be moved up to push the locking device <NUM> from inside the locking device <NUM>.

As the locking device <NUM> is pushed, the locked portion <NUM> may be unlocked, and the stand <NUM> may be unlocked accordingly.

The stand <NUM> may move down by its self-weight.

As shown in <FIG> and <FIG>, the stand <NUM> and the movable housing <NUM> and <NUM> may move down by their self-weights, and accordingly, the supporting portion <NUM> may pass through the opening <NUM> of the case <NUM> and the through hole <NUM> of the rear cover <NUM> and may be pulled down from the display device <NUM>.

Hence, the stand <NUM> may be placed in a middle position 110B by moving down from the pull-in position 110A.

As described above, the movable housing <NUM> and <NUM>, and the transmitter <NUM> and gear portion <NUM> coupled with the combining housing <NUM> may also be engaged and moved down with the stand <NUM>.

As the transmitter <NUM> is moved down, the piston of the gas cylinder <NUM> engaged with the transmitter <NUM> is moved down, and hence, the gas cylinder <NUM> may go into the expansion state B.

The supporting portion <NUM> may include a first supporter 112a and a second supporter 112b.

The stand <NUM> may include a rotation shaft <NUM> provided for the first and second supporters 112a and 112b to be rotated around.

The rotation shaft <NUM> may extend in an extending direction of the stand <NUM>, and may be arranged in the extending direction of the stand <NUM>.

The first and second supporters 112a and 112b may be each provided to be rotational around the rotation shaft <NUM>. Since the rotation shaft <NUM> vertically extends in the extending direction of the stand <NUM>, as described above, the first and second supporters 112a and 112b may be rotated horizontally.

When the stand <NUM> is placed in the pull-in position 110A, the first and second supporters 112a and 112b may be put into the through hole <NUM> and the opening <NUM> while contacting each other.

As described above, the through hole <NUM> or the opening <NUM> is formed to have a shape matching the shape of the supporter <NUM> and have a cross section in a similar size to the supporter <NUM>, so that the through hole <NUM> or the opening <NUM> may keep the first and second supporters 112a and 112b in the state of contacting each other.

In this case, horizontal rotation of the first or second supporter 112a or 112b around the rotation shaft <NUM> may be restricted by the through hole <NUM> or the opening <NUM>.

On the other hand, when the stand <NUM> is placed in the middle position 110B, the supporting portion <NUM> is pulled from the through hole <NUM> and the opening <NUM>, and the first and second supporters 112a and 112b may be rotated without restriction.

Hence, when the stand <NUM> is placed in the middle position 110B, the first and second supporters 112a and 112b may go into a rotational state.

Since the gas cylinder <NUM> is in the expansion state B, the gas cylinder <NUM> creates force by contraction and expansion, and the force may drive the gear portion <NUM> via the transmitter <NUM>.

As the gear portion <NUM> is driven, the stand gear <NUM> in gear with the gear portion <NUM> may be rotated, and the body portion <NUM> may be rotated by being engaged with the rotation with the stand gear <NUM>.

The supporting portion <NUM> coupled with the body portion <NUM> may be engaged with rotation of the body portion <NUM> for the first and second supporters 112a and 112b to be rotated in opposite directions.

The gear portion <NUM> may control rotation speed of the first and second supporters 112a and 112b. Specifically, a plurality of gears are arranged in the gear portion <NUM>, and the rotation speed of the first and second supporters 112a and 112b may be controlled appropriately based on the size or arrangement of each of the gears.

Furthermore, the gear portion <NUM> may help the supporting portion <NUM> rotate stably, and, as described above, control the rotation speed, thereby increasing reliability and beauty of the supporting portion <NUM> when the supporting portion <NUM> is rotated.

Although not shown, the stand <NUM> may include an elastic member provided to rotate the first and second supporters 112a and 112b.

The elastic member may be provided to rotate the first and second supporters 112a and 112b in opposite directions when the stand <NUM> is placed in the middle position 110B by pushing the first and second supporters 112a and 112b in the opposite directions.

The elastic member may be formed with a member such as a torsion spring.

Even when the elastic member pushes each of the first and second supporters 112a and 112b when the stand <NUM> is placed in the pull-in position 110A, the supporters 112a and 112b are not rotated but contained in the case <NUM> while staying in contact with each other because the supporting portion <NUM> is received in the through hole <NUM> or opening <NUM> as described above.

When the stand <NUM> is placed in the middle position 110B, the elastic member may push the first and second supporters 112a and 112b to rotate them.

The elastic member may be arranged to apply torque onto the first and second supporters 112a and 112b around the rotation shaft <NUM> as a rotation axis.

When elastic force of the elastic member is enough to push the first and second supporters 112a and 112b, in an examplary alternative construction the stand unit <NUM> may not include some components such as the aforementioned gas cylinder <NUM> and transmitter <NUM>.

The stand unit <NUM> may rotate the supporting portion <NUM> simply with the elastic member.

The stand unit <NUM> is not limited to what is described in the first embodiment, and may rotate the supporting portion <NUM> just with the force of the gas cylinder <NUM>.

Referring to <FIG> and <FIG>, rotation force is applied to the supporting portion <NUM> and the first and second supporters 112a and 112b are rotated in opposite directions until placed in front and back of the display device <NUM>, respectively.

The position of the stand <NUM> may be changed by rotation of the first and second supporters 112a and 112b from the middle position 110B to a supporting position 110C.

As the first and second supporters 112a and 112b are rotated around the rotation shaft <NUM> in opposite directions, the first and second supporters 112a and 112b may form a shape spreading around the rotation shaft <NUM>.

Accordingly, the first supporter 112a may be placed in front of the display device <NUM>, and the second supporter 112b may be placed in the back of the display device <NUM>.

As the stand <NUM> is placed in the supporting position 110C, the supporting portion <NUM> may support the display device <NUM> from front and back, thereby placing the display device <NUM> stably on the floor with the stand <NUM> when the display device <NUM> is installed in the stand-type.

In other words, the display device <NUM> may be supported on the floor in the stand-type with the stand <NUM> pulled out and placed in the supporting position 110C, and the display device <NUM> may be supported on the wall in the mount-type by pulling the stand <NUM> into the display device <NUM> in the pull-in position 110A.

The user may pull the stand <NUM> back into the display device <NUM> from the supporting position 110C by reversing the aforementioned process.

Specifically, the user may push the unfolded first and second supporters 112a and 112b in the supporting position 110C to be folded together, and push the supporting portion <NUM> upward to move the stand <NUM> upward, thereby forcing the locked portion <NUM> of the stand <NUM> to be inserted back into the locking device <NUM> and constrained by the locking device <NUM>.

When the stand <NUM> is locked in the locking device <NUM>, the stand <NUM> is placed back in the pull-in position 110A and not exposed.

In this way, the stand unit <NUM> may selectively pull the stand <NUM> into or out of the display device <NUM>. Accordingly, even in a situation where the display device <NUM> is to be installed in the mount-type that does not require the stand <NUM>, the stand <NUM> may be pulled into the display device <NUM>, thereby eliminating the need to keep the stand <NUM> separately and concerns about losing the stand <NUM>.

Furthermore, as described above, the user may pull the stand <NUM> out of the display device <NUM> by simply pushing the inner side of the through hole <NUM> formed at the bottom of the display device <NUM>.

When the conventional display device is placed in the stand-type, the display device needs to be held by something or be laid on the floor to attach a stand onto the display device. After the stand is attached onto the display device, the user needs to hold and stand the display device on the floor in the stand-type.

On the contrary, the display device <NUM> according to the first embodiment of the disclosure may be easily installed on the floor with the stand unit <NUM> that allows the user to pull a stand out of the display device <NUM> by pushing the bottom of the display device <NUM> while holding the display device <NUM>.

A second embodiment of the disclosure will now be described. Description of overlapping components with those of the first embodiment will not be repeated.

<FIG> shows a stand unit of a display device with a stand member pulled in, according to a second embodiment of the disclosure, <FIG> is a bottom perspective view of the display device with the stand member pulled in, according to the second embodiment of the disclosure, <FIG> shows the stand unit of the display device with the stand member partially pulled out, according to the second embodiment of the disclosure, <FIG> is a bottom perspective view of the display device with the stand member partially pulled out, according to the second embodiment of the disclosure, <FIG> shows the stand unit of the display device with the stand member fully pulled out, according to the second embodiment of the disclosure, and <FIG> is a bottom perspective view of the display device with the stand member fully pulled out, according to the second embodiment of the disclosure.

In the second embodiment, a stand unit <NUM> may include a stand <NUM> provided to be movable in the vertical direction, a case <NUM>, and a housing <NUM> fixed to the case <NUM> to pull the stand <NUM> in or out of the case <NUM>.

When the stand <NUM>, which has been pulled out, is pushed up, the stand <NUM> is moved up again by the external force, and at least a portion of the stand <NUM> in turn pushes the locking device <NUM> and accordingly, is constrained back in the locking device <NUM>, ending up with the stand <NUM> being pulled back into the case <NUM>.

In this way, the stand <NUM> may be moved up or down, and fixed at a particular position by the locking device <NUM>. Specifically, a highest position to which the stand <NUM> may be moved up may be defined by the locking device <NUM>, and a lowest position to which the stand <NUM> may be moved down may be defined by a stopper <NUM>.

The housing <NUM> may include a movable housing <NUM> through which the stand <NUM> passes and which is engaged with the stand <NUM> to be movable in the vertical direction, and a fixed housing <NUM> fixed to the case <NUM>.

The movable housing <NUM> may be movable against the fixed housing <NUM>, i.e., movable in a state of being coupled with the fixed housing <NUM>.

The stand unit <NUM> may further include a guide <NUM> for guiding vertical movement of the stand <NUM> and the movable housing <NUM>.

The guide <NUM> may include a rack <NUM> extending vertically, and a pinion <NUM> coupled in gear with the rack <NUM> and arranged in the movable housing <NUM>.

As the pinion is moved along the rack <NUM> that extends vertically, the movable housing <NUM> coupled to the pinion <NUM> and the stand <NUM> coupled to the movable housing <NUM> may be stably moved in the vertical direction.

The stand <NUM> may include a restricting member <NUM> for constraining the supporting portion <NUM>. When the stand <NUM> is pulled out of the display device <NUM>, the restricting member <NUM> may release the supporting portion <NUM> from the constraint to be unfolded. When the stand <NUM> is moved inside the display device <NUM>, the restricting member <NUM> may constrain the supporting portion <NUM> for the stand <NUM> to be stably moved inside the display device <NUM>.

As shown in <FIG> and <FIG>, when the display device <NUM> is in a packaged state or installed on the wall in the mount-type, the stand <NUM> may be placed in a pull-in position 210A.

When the stand <NUM> is placed in the pull-in position 210A, the movable housing <NUM> engaged with the stand <NUM> may be in a position corresponding to the pull-in position 210A of the stand <NUM>.

When the stand <NUM> is placed in the pull-in position 210A, it lies inside the case <NUM> or display device <NUM> and is not exposed.

When the stand <NUM> is placed in the pull-in position 210A, it is not pulled out of the through hole <NUM> and thus, not exposed, but it is possible for the user to push the stand <NUM> upward through the through hole <NUM> from the outside.

As shown in <FIG> and <FIG>, the stand <NUM> and the movable housing <NUM> may move down by their self-weights, and accordingly, the supporting portion <NUM> may pass through an opening <NUM> of the case <NUM> and the through hole <NUM> of the rear cover <NUM> and may be pulled down from the display device <NUM>.

Hence, the stand <NUM> may be placed in a middle position 210B by moving down from the pull-in position 210A.

The supporting portion <NUM> may include a first supporter 212a and a second supporter 212b. The first supporter 212a may be placed in front of the display device <NUM>, and the second supporter 212b may be placed in the back of the display device <NUM>.

The stand <NUM> may include a rotation shaft <NUM> provided for the first and second supporters 212a and 212b to be rotated around.

The rotation shaft <NUM> may extend in a direction parallel to the length of the display device <NUM>. Specifically, the rotation shaft <NUM> may extend in the horizontal direction of the display device <NUM> and may be arranged in the horizontal direction of the display <NUM>.

The first and second supporters 212a and 212b may be each provided to be rotational around the rotation shaft <NUM>. Since the rotation shaft <NUM> extends in the horizontal direction of the display device <NUM>, as described above, the first and second supporters 212a and 212b may be turned to the front and back with respect to the horizontal direction of the display device <NUM>.

Specifically, the first supporter 212a may be turned to the front of the display device <NUM>, and the second supporter 212b may be turned to the back of the display device <NUM>.

When the stand <NUM> is placed in the pull-in position 210A, the first and second supporters 212a and 212b may be put into the through hole <NUM> and the opening <NUM> while contacting each other. The through hole <NUM> or the opening <NUM> may keep the first and second supporters 212a and 212b in the state of contacting each other.

On the other hand, when the stand <NUM> is placed in the middle position 210B, the supporting portion <NUM> is pulled from the through hole <NUM> and the opening <NUM>, and the first and second supporters 212a and 212b may be rotated without restriction.

Hence, when the stand <NUM> is placed in the middle position 210B, the first and second supporters 212a and 212b may go into a rotational state.

Although not shown, the stand <NUM> may include an elastic member provided to rotate the first and second supporters 212a and 212b.

The elastic member may be provided to rotate the first and second supporters 212a and 212b in opposite directions when the stand <NUM> is placed in the middle position 210B by pushing the first and second supporters 212a and 212b in the opposite directions.

Even when the elastic member pushes each of the first and second supporters 212a and 212b when the stand <NUM> is placed in the pull-in position 210A, the first and second supporters 212a and 212b are not rotated but contained in the case <NUM> while staying in contact with each other because the supporting portion <NUM> is received in the through hole <NUM> or opening <NUM> as described above.

When the stand <NUM> is placed in the middle position 210B, the elastic member may push the first and second supporters 212a and 212b to be rotated.

The elastic member may be arranged to be able to apply torque onto the first and second supporters 212a and 212b around the rotation shaft <NUM> as a rotation axis.

The stand <NUM> may include a restricting member <NUM> to constrain the first and second supporters 212a and 212b. The restricting member <NUM> may restrict the first and second supporters 212a and 212b from being rotated by the elastic member at the pull-in position 210A or the middle position 210B.

Specifically, while the stand <NUM> is moving between the pull-in position 210A and the middle position 210B, the restricting member <NUM> may constrain the first and second supporters 212a and 212b for the stand <NUM> to be moved stably.

Although not shown, the restricting member <NUM> is provided to be hooked with the first and second supporters 212a and 212b inside the body portion <NUM>. It is not, however, limited thereto, but the restricting member <NUM> may be provided in various forms to constrain or release the first and second supporters 212a and 212b.

The stand unit <NUM> further includes a gas cylinder to push the supporting portion <NUM> to rotate the first and second supporters 212a and 212b.

The gas cylinder's main body may be fixed to the case <NUM> and a piston of the gas cylinder may be engaged with the movable housing <NUM> to be moved.

Accordingly, the gas cylinder may contract or expand as the stand <NUM> and the movable housing <NUM> are moved vertically, and the force created from the contraction or expansion may be transmitted to the supporting portion <NUM> to rotate each of the first and second supporters 212a and 212b.

With the gas cylinder included in the stand unit <NUM>, the elastic member may not be included in the stand unit <NUM>.

The guide <NUM> may guide the moving direction of the stand <NUM> through the rack <NUM> and the pinion <NUM> and simultaneously, control the moving speed of the stand <NUM>. For example, the speed at which the stand <NUM> moves up or down may be controlled by adjusting the size or arrangement of the rack <NUM> and pinion <NUM>.

Furthermore, the guide <NUM> may be provided to allow the stand <NUM> to be stably moved in gear with the rack <NUM> and the pinion <NUM>, and may increase reliability and beauty of the stand <NUM> by controlling the rising or falling speed as described above.

Referring to <FIG> and <FIG>, rotation force is applied to the supporting portion <NUM> and the first and second supporters 212a and 212b are rotated in opposite directions until placed in front and back of the display device <NUM>, respectively.

When the movable housing <NUM> is restricted by the stopper <NUM> from moving downward, the body portion <NUM> of the stand <NUM> that is moved by being engaged with the movable housing <NUM> may be restricted from moving as well.

The restricting member <NUM> arranged inside the body portion <NUM> is not constrained by this but may be moved by its self-weight further down than the body portion <NUM> is.

The restricting member <NUM> may vertically slide in the body portion <NUM>. The restricting member <NUM> may be moved down and constraints of the restricting member <NUM> on the first and second supporters 212a and 212b may be released.

The restricting member <NUM> releases constraints on the first and second supporters 212a and 212b in a position at which the movable housing <NUM> is restricted by the stopper <NUM> from moving, and hence the first and second supporters 212a and 212b are rotated for the stand <NUM> to be finally in the supporting position 210C.

As the first and second supporters 212a and 212b are rotated around the rotation shaft <NUM> in opposite directions, the first and second supporters 212a and 212b may form a shape spreading around the rotation shaft <NUM>.

Accordingly, the first supporter 212a may be placed in front of the display device <NUM>, and the second supporter 212b may be placed in the back of the display device <NUM>.

A third embodiment of the disclosure will now be described. Description of overlapping components with those of the previous embodiments will not be repeated.

<FIG> shows a stand unit of a display device with a stand member pulled in, according to a third embodiment of the disclosure, <FIG> is a bottom perspective view of the display device with the stand member pulled in, according to the third embodiment of the disclosure, <FIG> shows the stand unit of the display device with the stand member partially pulled out, according to the third embodiment of the disclosure, <FIG> is a bottom perspective view of the display device with the stand member partially pulled out, according to the third embodiment of the disclosure, <FIG> shows the stand unit of the display device with the stand member fully pulled out, according to the third embodiment of the disclosure, and <FIG> is a bottom perspective view of the display device with the stand member fully pulled out, according to the third embodiment of the disclosure.

In the third embodiment, the stand unit <NUM> may include a stand <NUM> provided to be movable in the vertical direction, a case <NUM>, and a housing <NUM> fixed to the case <NUM> to allow the stand <NUM> to be pulled in or out of the case <NUM>.

The housing <NUM> may include a first housing 330a coupled with the case <NUM> and a second housing 330b coupled with the first housing 330a. Certain space may be formed between the first and second housings 330a and 330b for the stand <NUM> to be inserted thereto.

The stand <NUM> is inserted to the certain space, and the first and second housings 320a and 320b may be combined. The stand <NUM> may be moved vertically in the certain space.

The stand <NUM> may include a body portion <NUM> inserted to the housing <NUM>, a locked portion <NUM> arranged on the top of the body portion <NUM> and inserted to and constrained by a locking device <NUM>, and the supporting portion <NUM> provided to be pulled out of the display device <NUM> when the stand <NUM> is unlocked and thus support the display device <NUM> from the floor.

The second housing 330b may include a guide projection <NUM> for guiding movement of the body portion <NUM>. It is not, however, limited thereto, and the guide projection <NUM> may be arranged in the first housing 330a in another embodiment.

The body portion <NUM> may include a rail <NUM> to which the guide projection <NUM> is inserted. The body portion <NUM> may be vertically moved while the guide projection <NUM> is inserted to the rail <NUM>.

Accordingly, the body portion <NUM> may be moved along the direction in which the rail <NUM> extends.

At least a portion of the rail <NUM> may extend straight vertically, and some other portion of the rail <NUM> may be curved in the vertical direction.

Hence, the body portion <NUM> may be moved vertically when the guide projection <NUM> is in the straight portion of the rail <NUM>, and may be rotated along the curve of the rail <NUM> when the guide projection <NUM> is in the curved portion. This will be described in more detail later.

A process in which the stand <NUM> is pulled in or pulled out by the stand unit <NUM> will now be described in detail.

As shown in <FIG> and <FIG>, when the display device <NUM> is in a packaged state or installed on the wall in the mount-type, the stand <NUM> may be placed in a pull-in position 310A.

When the stand <NUM> is placed in the pull-in position 310A, the supporting portion <NUM> may be located in a receiving groove <NUM> (see <FIG>) formed on the bottom side of the case <NUM>.

The supporting portion <NUM> may be provided to be perpendicular to the body portion <NUM>, and when the stand <NUM> is placed in the pull-in position 310A, may lie along the length of the display device <NUM>.

In other words, when the stand <NUM> is placed in the pull-in position 310A, the supporting portion <NUM> may lie in the horizontal direction of the display device <NUM>.

The receiving groove <NUM> may also be formed to extend along the horizontal direction of the display device <NUM>.

When the stand <NUM> is placed in the pull-in position 310A, it lies inside the case <NUM> or display device <NUM> and is not exposed.

When the stand <NUM> is placed in the pull-in position 310A, it is not pulled out of the through hole <NUM> and thus, not exposed, but it is possible for the user to push the stand <NUM> upward through the through hole <NUM> from the outside.

As shown in <FIG> and <FIG>, the stand <NUM> may move down by the self-weight, and accordingly, the supporting portion <NUM> may be pulled out of the receiving groove <NUM> of the case <NUM> and may pass through the through hole <NUM> of the rear cover <NUM>, and the body portion <NUM> may be pulled down through the opening323 of the case <NUM>.

Hence, the stand <NUM> may be placed in a middle position 310B by moving down from the pull-in position 310A.

While the stand <NUM> is moving from the pull-in position 310A to the middle position 310B, the guide projection <NUM> may be placed in a first area 316a of the rail <NUM>. The first area 316a is an area in which the rail <NUM> extends straight in the vertical direction. In the first area 316a, the guide projection <NUM> may guide the stand <NUM> for the body portion <NUM> to be moved in the vertical direction.

The supporting portion <NUM> may then be moved down by keeping the direction in which the supporting portion <NUM> lies that corresponds to the horizontal direction of the display device <NUM>.

Subsequently, when the guide projection <NUM> is located in a second area 316b of the rail <NUM>, the body portion <NUM> may be moved down by being rotated in one direction along the curve of the second area 316b. The supporting portion <NUM> may be moved down by being engaged with the body portion <NUM> and rotated in one direction.

Although not shown, the stand unit <NUM> may further include a gear portion coupled to the body portion <NUM>. The gear portion may include a plurality of gears, in which case at least one gear may be coupled to the body portion <NUM> and at least another gear may be coupled to the housing <NUM>.

Moving speed of the stand <NUM> may be controlled by the gear portion, enabling the stand <NUM> to be stably moved, thereby increasing reliability and beauty of the stand <NUM>.

Referring to <FIG> and <FIG>, when the guide projection <NUM> reaches an end 316c of the second area 316b of the rail <NUM>, the guide projection <NUM> may be stuck in the rail <NUM> and the body portion <NUM> may not move down any longer and keep the fallen state.

The stand <NUM> may then be in a supporting position 310C at which to support the display device <NUM>.

The supporting portion <NUM> may be engaged with the body portion <NUM> and rotated along the curve of the rail <NUM>, e.g., about <NUM> degrees in one direction.

In other words, the length and curvature of the curve of the second area 316b may be adjusted such that the body portion <NUM> may be rotated about <NUM> degrees until the guide projection <NUM> reaches the end 316c.

As the supporting portion <NUM> is rotated about <NUM> degrees, the supporting portion <NUM> may lie in a direction from front to back of the display device <NUM>. Hence, the supporting portion <NUM> may stably support the display device <NUM>.

Although not shown, a stopper may be included to keep the state in which the guide projection <NUM> and the end 316c come into contact with each other.

The stopper may be a section of the rail <NUM> extending from the end 316c to the opposite for restricting the guide projection <NUM> from moving, and may be provided separately to press the body portion <NUM> to restrict movement of the body portion <NUM>.

The stand <NUM> may be rotated to change the direction in which the supporting portion <NUM> lies while moving from the middle position 310B to the supporting position 310C.

Hence, when the stand <NUM> is placed in the supporting position 310C, the stand unit <NUM> may place the stand <NUM> to support the display device <NUM>.

The stand <NUM> is not pulled out of the receiving groove <NUM>' and thus, not exposed, but it is possible for the user to pull out the stand <NUM> through the receiving groove <NUM>'.

To pull the stand <NUM> out of the display device <NUM>, the user may pull out the stand <NUM> from the receiving groove <NUM>'.

When the stand <NUM> is pulled out, it may be turned down around the first rotation shaft <NUM> by its self-weight.

Referring to <FIG>, the stand <NUM> may be turned down by its self-weight, and thus pulled down from the display device <NUM>.

Hence, the stand <NUM> may be placed in a middle position 410B by moving down from the pull-in position 410A.

When the stand <NUM> is placed in the middle position 410B, the user may turn the stand <NUM> around the second rotation shaft <NUM>, in which case since the second rotation shaft <NUM> extends vertically, the stand <NUM> may be turned to the front and back of the display device <NUM>.

Although not shown, the stand unit <NUM> may further include a gear portion arranged between the stand <NUM> and the hinge part <NUM>. The gear portion may include a plurality of gears, in which case at least one gear may be coupled to the stand <NUM> and at least another gear may be coupled to the hinge part <NUM>.

Moving speed of the stand <NUM> may be controlled by the gear portion, enabling the stand <NUM> to be stably turned, thereby increasing reliability and beauty of the stand <NUM>.

Referring to <FIG>, the stand <NUM> is turned to the front and back of the display device <NUM> to be in a supporting position 410C at which to support the display device <NUM>.

The stand <NUM> may be rotated about <NUM> degrees against the hinge part <NUM>.

The hinge part <NUM> may include a stopper (not shown) for the stand <NUM> to be rotated about <NUM> degrees against the hinge part <NUM>. The stopper may restrict rotation of the stand <NUM> such that the stand <NUM> is not rotated more than about <NUM> degrees against the hinge part <NUM>.

The stand unit <NUM> may further include a stand check member (not shown) to prevent the stand <NUM> from being turned in the opposite direction after the stand <NUM> is turned about <NUM> degrees.

The stand check member may check rotation of the stand <NUM> to prevent the stand <NUM> from being turned to any direction after the stand <NUM> is rotated <NUM> degrees against the hinge part <NUM>, thereby enabling the stand <NUM> to stably support the display device <NUM>.

A fifth embodiment of the disclosure will now be described. Description of overlapping components with those of the previous embodiments will not be repeated.

<FIG> is a rear perspective view of the display device with the stand member pulled in, according to the fifth embodiment of the disclosure, <FIG> is a rear perspective view of the display device with the stand member pulled in, according to the fifth embodiment of the disclosure, and <FIG> is a rear perspective view of the display device with the stand member fully pulled out, according to the fifth embodiment of the disclosure.

In the fifth embodiment, the display device <NUM> may include a stand unit <NUM> that may be pulled in or out of a rear side 90b" of a rear cover <NUM>".

The stand unit <NUM> may include a stand <NUM> provided to support the display device <NUM> when the stand unit <NUM> is pulled out of the rear cover <NUM>", a hinge part <NUM> provided for the stand <NUM> to be turned, and a rotation shaft <NUM> provided for the stand <NUM> to be turned.

Referring to <FIG>, the stand <NUM> may be in a pull-in position 510A, when the display device <NUM> is in a packaged state or installed on the wall in the mount-type.

When the stand <NUM> is placed in the pull-in position 510A, it lies inside the rear cover <NUM>" or display device <NUM> and is not exposed.

In the pull-in position 510A, the stand <NUM> may be pulled into a first receiving groove <NUM>" formed on the rear side 90b" of the rear cover <NUM>".

The hinge part <NUM> and the rotation shaft <NUM> may be pulled in a second receiving groove <NUM>" formed inside the rear cover <NUM>".

The stand <NUM> is not pulled out of the first receiving groove <NUM>" and thus, not exposed, but it is possible for the user to pull out the stand <NUM> through the first receiving groove <NUM>".

To pull the stand <NUM> out of the display device <NUM>, the user may push the stand <NUM> downward through the first receiving groove <NUM>".

The stand <NUM> and the hinge part <NUM> may be integrally formed. Furthermore, the rotation shaft <NUM> may penetrate the hinge part <NUM>. Accordingly, the hinge part <NUM> and the rotation shaft <NUM> may be moved down by being engaged with the stand <NUM>.

In this case, the hinge part <NUM> and the rotation shaft <NUM> may be moved down along the second receiving groove <NUM>".

The first receiving groove <NUM>" may be formed on the rear side 90b" of the rear cover <NUM>" to vertically extend to the bottom of the rear cover <NUM>".

The second receiving groove <NUM>" may be formed inside the rear cover <NUM>" to extend vertically like the first receiving groove <NUM>".

Although not shown, there may be an anti-deviation member included to prevent the stand <NUM> placed in the pull-in position 510A from deviating from the pull-in position 510A. Accordingly, the stand <NUM> may be prevented from sliding down from the pull-in position 510A simply by external force.

Referring to <FIG>, the stand <NUM> may slide down when pushed by the user, and may thus be pulled down from the display device <NUM>.

Hence, the stand <NUM> may be placed in a middle position 510B by moving down from the pull-in position 510A.

When the stand <NUM> is placed in the middle position 510B, the hinge part <NUM> and the rotation shaft <NUM> may be in the middle position 510B as well.

In the middle position 510B, the rotation shaft <NUM> may be located at the lower end 95a" of the second receiving groove <NUM>". In this case where the stand <NUM> is placed in the middle position 510B, the rotation shaft <NUM> reaches the lower end 95a" and is prevented from moving further down, and accordingly, the stand <NUM> may be restricted from moving further down from the middle position 510B.

Subsequently, the stand <NUM> may be turned around the rotation shaft <NUM> from the middle position 510B. The rotation shaft <NUM> may extend in the horizontal direction of the display device <NUM>.

Hence, the stand <NUM> may be turned to the front and back of the display device <NUM>.
