Description

display device

[0001] The present invention relates to a display device including a stand positioned on the back surface of a main body.

[0002] As the information society develops, the demand for display devices is also increasing in various forms, and in response to this, recent display devices include liquid crystal displays (LCDs), field emission displays (FEDs), plasma display panels (PDPs), and electroluminescence devices.

[0003] The liquid crystal panel of the liquid crystal display device includes a liquid crystal layer and a TFT substrate and a color filter substrate facing each other with the liquid crystal layer interposed therebetween, and can display an image using light provided from a backlight unit.

[0004] As an example of an electroluminescent device (ELD), an active-matrix type organic light-emitting display device is commercially available. Because OLED displays are self-luminous, they do not require a backlight and offer advantages over liquid crystal displays (LCDs) in terms of response speed, viewing angle, and other factors. Therefore, they are attracting attention as next-generation displays.

[0005] Recently, there's a growing preference for display devices that are freely movable, rather than fixed. There's a growing need to improve work efficiency by allowing the display device to be moved freely within the office.

[0054] Figure 1 is a front perspective view showing a mounting state of a display device (10) according to one embodiment of the present invention.

[0055] A display device (10) includes a display (151) that outputs an image on the front and may include a body in the shape of a rectangular parallelepiped with a predetermined thickness. A control unit that drives the display (151), an audio output unit that outputs sound, and a power supply unit that supplies power to the display (151) and the control unit may be mounted inside the body.

[0056] Recently, a display device (10) may be included that includes a rechargeable battery for wireless use. Data can be transmitted and received via wireless communication, and content and data can be transmitted and received via broadcast reception or a network.

[0057] The wireless type can perform short-range wireless communication with other electronic devices located nearby. The display device (10) can be connected to a network with other electronic devices according to communication standards such as Bluetooth, RFID (Radio Frequency Identification), IrDA (Infrared Data Association), UWB (Ultra Wideband), ZigBee, and DLNA (Digital Living Network Alliance), for example.

[0058] In addition to wireless communication, it may include a USB terminal, CVBS (Composite Video Banking Sync) terminal, component terminal, S-video terminal (analog), DVI (Digital Visual Interface) terminal, HDMI (High Definition Multimedia Interface) terminal, RGB terminal, D-SUB terminal, etc. for transmitting and receiving data via wire.

[0059] You can access a specific web page through the connected network or another network linked to the connected network. In other words, you can access a specific web page through the network and transmit or receive data to or from the server. Additionally, you can receive content or data provided by content providers or network operators.

[0060] That is, content such as movies, advertisements, games, VOD, and broadcast signals, as well as related information, can be received from content providers or network providers via the network. Furthermore, firmware update information and update files provided by network operators can be received. Furthermore, data can be transmitted to the Internet, content providers, or network operators.

[0061] The display (151) can generate a driving signal by converting a video signal, data signal, OSD signal, control signal, etc. processed by the control unit or a video signal, data signal, control signal, etc. received from the interface unit. The display (151) can include a display panel having a plurality of pixels.

[0062] The plurality of pixels provided on the display panel may have RGB sub-pixels. Alternatively, the plurality of pixels provided on the display panel may have RGBW sub-pixels. The display (151) may convert image signals, data signals, OSD signals, control signals, etc. processed by the control unit to generate driving signals for the plurality of pixels.

[0063] The display (151) can be a PDP (Plasma Display Panel), an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diode), a flexible display, etc., and may also be a 3D display. The 3D display (151) can be divided into a glasses-free type and a glasses type.

[0064] The display device (10) includes a display (151) that occupies most of the front surface area and a case that covers the rear side of the display (151) and packages the display (151).

[0065] Recently, display devices (10) can utilize displays (151) that can be bent, such as LEDs (Light Emitting Diodes) or OLEDs (Organic Light Emitting Diodes), to implement curved screens beyond flat surfaces.

[0066] Previously, LCDs were primarily used because they were unable to emit light on their own, so they relied on backlight units for light. Backlight units are devices that evenly distribute light from a light source to the liquid crystal display (LCD) located at the front. As backlight units have become thinner, thinner LCDs have become possible. However, it has been difficult to implement backlight units using flexible materials, and when the backlight unit is bent, it becomes difficult to supply light evenly to the LCD, causing screen brightness to fluctuate.

[0067] On the other hand, in the case of LEDs or OLEDs, since each element that forms a pixel emits light on its own, it is possible to implement a curved display without using a backlight unit. In addition, since each element emits light on its own, even if the positional relationship with neighboring elements changes, its own brightness is not affected, so a curved display (151) can be implemented using LEDs or OLEDs.

[0068] OLED (Organic Light-Emitting Diodes) panels made their debut in the mid-2010s and are rapidly replacing LCDs in the small- and medium-sized display market. OLEDs utilize the self-luminous phenomenon, where fluorescent organic compounds emit light when current flows through them. Their image quality response speed is faster than that of LCDs, resulting in virtually no afterimages when displaying video.

[0069] OLED uses three types of fluorescent organic compounds with self-luminous functions: red, green, and blue. It is a luminescent display product that utilizes the phenomenon in which electrons injected from the cathode and anode and positively charged particles combine within the organic material to emit light on their own, so there is no need for a backlight (backlight device) that reduces color.

[0070] LED (Light Emitting Diode) panels are a technology that uses one LED element as one pixel, and since the size of the LED element can be reduced compared to the past, a flexible display (151) can be implemented. Devices previously called LED TVs used LEDs as a light source for a backlight unit that supplied light to an LCD, and the LEDs themselves did not form a screen.

[0071] A display may include a plurality of pixels (R, G, B). The plurality of pixels (R, G, B) may be formed in each area where a plurality of data lines and a plurality of gate lines intersect. The plurality of pixels (R, G, B) may be arranged or arranged in a matrix form.

[0072] For example, a plurality of pixels (R, G, B) may include a red (Red, hereinafter referred to as 'R') sub-pixel, a green (Green, 'G') sub-pixel, and a blue (Blue, 'B') sub-pixel. The plurality of pixels (R, G, B) may further include a white (White, hereinafter referred to as 'W') sub-pixel.

[0073] The side of the display (151) that displays an image may be referred to as the front or front. When the display (151) displays an image, the side that cannot be observed may be referred to as the rear or back. Meanwhile, the display (151) may be configured as a touch screen and may be used as an input device in addition to an output device.

[0074] The control unit may include at least one processor, and may control the overall operation of the display device (10) using the processor included therein. Here, the processor may be a general processor such as a central processing unit (CPU). Of course, the processor may be a dedicated device such as an ASIC or another hardware-based processor.

[0075] The control unit can demultiplex a stream input through a tuner unit, a demodulator unit, an external device interface unit (112), or a network interface unit (113), or process demultiplexed signals to generate and output signals for video or audio output.

[0076] The image signal processed by the control unit can be input to the display (151) and displayed as an image corresponding to the image signal. In addition, the image signal processed by the control unit can be input to an external output device through the external device interface unit.

[0077] The voice signal processed by the control unit can be output as sound to the audio output unit. Additionally, the voice signal processed by the control unit can be input to an external output device through the external device interface unit.

[0078] In addition, the control unit can control the display device (10) by a user command input through the user input interface unit or an internal program. Meanwhile, the control unit can control the display (151) to display an image. At this time, the image displayed on the display (151) may be a still image or a moving image, and may be a 2D image or a 3D image.

[0079] Meanwhile, the control unit can cause a predetermined 2D object to be displayed within an image displayed on the display (151). For example, the object can be at least one of a connected web screen (newspaper, magazine, etc.), EPG (Electronic Program Guide), various menus, widgets, icons, still images, videos, and text.

[0080] FIG. 2 is a rear perspective view illustrating a vertically mounted state of a display device (10) according to one embodiment of the present invention, and FIG. 3 is a rear perspective view illustrating a horizontally mounted state of a display device (10) according to one embodiment of the present invention.

[0081] The display device (10) of the present invention may include a stand positioned on the back surface. It can be stored in a stand storage portion concavely recessed into the back surface of the display device (10), and when positioned in the stand storage portion, the stand can form the same plane as the back surface (110) of the main body of the display device (10).

[0082] The stand of the present invention is rotatable and can be switched between a first state in which it is arranged in the direction of the long side of the main body (100) as shown in Fig. 2 and a second state in which it is arranged in the direction of the short side of the main body (100) as shown in Fig. 3. In consideration of these features, it is referred to as a swivel stand (200) hereinafter.

[0083] The swivel stand (200) may include a stand leg (210), a stand hinge (230), and a swivel unit (220).

[0084] The stand leg (210) is a bar-shaped member inserted into the stand mounting portion (111) formed on the back surface (110) of the main body, and the first end is located in the central portion of the main body, and the second end extended from the first end contacts the mounting surface to support the back surface of the main body (100) so that the main body (100) can be erected as shown in FIGS. 2 and 3.

[0085] To ensure stable support, the second end of the stand leg (210) may include a stand foot (215). As shown in Fig. 2, the stand foot may be extended (③) in the width direction of the stand leg (210) to enhance the support force.

[0086] When the second end of the stand leg (210) is held and pulled in the rear direction (①), the angle of the stand leg (210) with the rear surface (110) of the main body changes by the stand hinge (230). The stand hinge (230) is connected to the first end of the stand leg (210) and can change the angle between the rear surface (110) of the main body and the second end of the stand leg (210).

[0087] The stand hinge (230) can support the display device (10) in either a vertical mounting state as shown in FIG. 2 or a horizontal mounting state as shown in FIG. 3 by switching the extension direction of the stand leg (210) to one of the first and second states.

[0088] The swivel unit (220) is connected to a stand hinge (230) and can rotate (Fig. 3, ④) so that the position of the stand leg (210) changes on the back surface (110) of the main body. For the rotation of the swivel unit (220), the swivel unit (220) has a circular shape and may include a hole (112, see Fig. 4) to which the swivel hinge is connected on the back surface (110) of the main body.

[0089] The swivel stand (200) of the present embodiment is characterized in that the length of the stand leg (210) can also be changed (②). Accordingly, the stand leg (210) may include a first leg (211) and a second leg (212) that can slide relative to the first leg (211).

[0090] FIG. 4 is an exploded perspective view showing the rear structure of a display device (10) according to one embodiment of the present invention.

[0091] The first leg (211) includes a space in the front in which the second leg (212) is stored, and may include leg rails (2114) in which both widthwise sides of the second leg (212) are stored.

[0092] The first leg (211) may include a shaft coupling portion (2115) connected to a stand hinge (230) at the first end. The shaft coupling portion (2115) includes a stand hole through which a stand shaft of the stand hinge (230) passes, and the stand hole may extend in a width direction perpendicular to the longitudinal direction of the first leg (211).

[0093] Figure 5 is a cross-section taken along line AA of Figure 2. The shaft hole (2116) is located in the middle of the thickness of the leg stand to minimize interference with the hinge bracket (233) of the stand hinge (230) when the stand leg (210) rotates.

[0094] Figures 6 and 7 are drawings illustrating changes in the length of a stand leg (210) of a display device (10) according to one embodiment of the present invention. The drawings are viewed from the front of the stand leg (210), and illustrate a first leg (211) and a second leg (212) that slides in the longitudinal direction of the stand leg (210) in front of the first leg (211).

[0095] FIG. 6 illustrates a state in which the second leg (212) and the first leg (211) overlap to shorten the length of the stand leg (210) (shortened state), and FIG. 7 illustrates a state in which the second leg (212) slides and is pulled out in the direction of the second end of the first leg (211) (tensioned state).

[0096] A leg rail (2114) may be formed in which the front of the first leg (211) is concavely inserted and the two ends of the second leg (212) are inserted on both sides. A leg stopper (213) may be included to fix the position between the first leg (211) and the second leg (212).

[0097] Fig. 8 is a drawing illustrating a leg stopper (213) of a display device (10) according to one embodiment of the present invention. The leg stopper (213) may include a stopper button (2132) located at a first end of a first leg (211) and a spring (2135) that presses the stopper button (2132) laterally.

[0098] The stopper button (2132) may include a stopper protrusion (2133) that is inserted into a stopper groove (2113) formed in the first leg (211). The stopper grooves (2113) may be formed in a plurality of pieces spaced apart from each other in the longitudinal direction of the first leg (211), and when the stopper protrusions (2133) are inserted into the stopper grooves (2113), the sliding movement of the second leg (212) may be restricted and the length of the stand leg (210) may be fixed.

[0099] When the stopper protrusion (2133) is inserted into the stopper groove (2113), the stopper button (2132) can protrude (⑤) laterally of the first leg (211) as shown in Fig. 7. When the user presses the protruding stopper button (2132), the stopper protrusion (2133) is released from the stopper groove (2113), and the position of the second leg (212) can be changed.

[0100] When the stopper protrusion (2133) is not inserted into the stopper groove (2113), the stopper button (2132) does not protrude laterally from the stand leg (210) as shown in FIG. 6, so that the stand leg (210) can be inserted into the stand mounting portion (111).

[0101] The stopper bracket (2131) is coupled to cover the stopper button (2132) in the front direction of the second leg (212), and the stopper button (2132) and the spring (2135) can be fixed to the second leg (212). Since the leg stopper (213) must be positioned at a position where the first leg (211) and the second leg (212) overlap, it can be positioned at the second end of the first leg (211) and the first end of the second leg (212) in the state of FIG. 7 where the first leg (211) and the second leg (212) overlap to a minimum.

[0102] When the leg stopper (213) is connected to the first leg (211), the leg stopper (213) is positioned in the direction of the second end in the shortened state of the stand leg (210) as shown in FIG. 5, so an additional space must be formed in the stand mounting portion (111) in which the leg stopper (213) can be mounted.

[0103] However, when fastened to the first end of the second leg (212) as in the present embodiment, the leg stopper (213) is arranged parallel to the stand hinge (230) in a shortened state as shown in FIG. 6 and can be stored in the swivel unit (220).

[0104] A length-limiting protrusion (2112) positioned adjacent to the second end of the first leg may be included to prevent the second leg (212) from being separated from the first leg. When the second leg (212) slides in the direction in which the length of the stand leg (210) increases, and the stopper bracket (2131) comes into contact with the protrusion (2112), the second leg (212) can no longer move in the direction of the second end.

[0105] Fig. 9 illustrates a stand foot (215) of a display device (10) according to one embodiment of the present invention. The stand foot (215) of the present invention is positioned at the second end of the second leg (212) and is expandable in the width direction. The stand foot (215) can solve the problem of the support surface area being narrow due to the narrow width of the stand leg (210).

[0106] The stand foot (215) may include a foot bracket (2156) that is fastened to the second end of the second leg (212) and a slide foot (2152) that is inserted and withdrawn into the interior of the foot bracket. The slide foot (2152) may be inserted so as to have the same width as the width of the first league when the stand leg (210) is stored in the stand mounting portion (111) (see FIG. 6).

[0107] When the second end of the stand leg (210) is brought into contact with the surface and the display device (10) body (100) is placed on the surface, the slide foot (2152) can be pulled out as shown in FIG. 7.

[0108] A rack gear (2154) extended from the slide foot (2152) is engaged with a pinion gear fixed to the second leg (212), and the pinion gear (2155) engages with the rack gear (2154) of a pair of slide feet (2152) so that the pair of slide feet (2152) can move simultaneously.

[0109] That is, when a user pulls the slide foot (2152) on one side, the slide foot (2152) on the other side can also be pulled out. In order to guide the movement of the slide foot (2152), a guide protrusion (2153) formed on the slide foot (2152) and a guide slot (2157) formed on the foot bracket (2156) may be included.

[0110] After the foot bracket is fastened, a foot cover (2151) can be attached to cover the foot bracket (2156). The foot cover (2151) and the slide foot (2152) can prevent the swivel stand (200) from slipping on the surface by using a material with high friction.

[0111] FIG. 10 is a drawing illustrating a swivel unit (220) and a stand hinge (230) of a display device (10) according to one embodiment of the present invention.

[0112] The stand hinge (230) may include a hinge shaft (231) and a hinge bracket (233) that secures the hinge shaft (231) to the swivel unit (220). The hinge bracket (233) may include an axis portion that is fastened to both sides of the hinge shaft (231) that passes through the shaft hole (2116) and a fastening portion that extends from the axis portion and is fastened to the swivel unit (220). The hinge bracket (233) of the present embodiment is of a type that is fastened to both sides of the swivel unit (220), but may also be configured as an integrated unit.

[0113] Referring to FIG. 4, the swivel unit (220) may include a base plate (221), a rotation plate (226), a fixing ring (222), an auxiliary plate (227), and a swivel cover (225) from the front (bottom in the drawing).

[0114] The base plate (221) and the fixed ring (222) are fixed to the main body (100) and do not rotate, and the rotation plate (226) is interposed between the base plate (221) and the fixed ring (222) and can rotate. The auxiliary plate (227) and the swivel cover (225) connected to the rotation plate (226) can also rotate together with the rotation plate (226).

[0115] The swivel cover is fastened to the back surface of the rotating swivel plate (226) or auxiliary plate (227) and serves to cover the swivel structure and hinge structure so that they are not exposed to the outside. The swivel cover (225) is fitted into the swivel hole (112) of the back surface (110) of the main body and has a circular shape. A groove may be formed in a ㄷ shape in the part corresponding to the stand leg (210) so that the stand leg (210) can perform a hinge movement.

[0116] When the stand leg (210) is opened in the rear direction as shown in FIG. 5, a front-protruding projection (2255) may be included on both sides of the first end of the stand leg (210) so that the hinge structure is not exposed through the open space of the leg storage portion (111).

[0117] Fig. 11 is a drawing illustrating a method of fastening a center bracket (223) and a base plate (221) of a display device (10) according to one embodiment of the present invention. A groove may be formed on the front of the fixed ring (222) so that the periphery of the rotation plate (226) may be inserted, and the fixed ring (222) and the base plate (221) may be fastened using a fastener such as a screw.

[0118] A center bracket (223) may be further included to guide the center of rotation of the rotation plate (226). The rotation plate (226) can rotate along a swivel rail along which the outer surface of the rotation plate (226) formed by the fixing ring (222) and the base plate (221) moves, but the center bracket (223) may be fixed to the base plate (221) by penetrating the rotation plate (226) to fix the center of rotation of the rotation plate (226).

[0119] A screw (2235) inserted into a pawl nut (2211) positioned on a base plate (221) can pass through a screw hole (2233) of a center bracket (223). The center bracket (223) can be fixed to the base plate (221) through the screw (2235). The pawl nut (2211) can be positioned at a position that is offset from the center of rotation of the rotation plate (226) so that the center bracket (223) does not rotate together with the rotation plate (226).

[0120] If the pammut (2211) is positioned at the center of the center bracket (223), i.e., the center of rotation of the rotation plate (226), the screw may be loosened as the center bracket (223) rotates, causing the swivel unit (220) to be disassembled, and thus may be misaligned. In order to limit the rotation of the center bracket (223), the base plate (221) may further include a fixing pin (2212) protruding at a position spaced apart from the center of the rotation plate (226).

[0121] The front of the center bracket (223) includes a groove (2231) into which a nut (2211) is inserted and a groove (2232) into which a fixing pin (2212) is inserted, as shown in FIG. 10, and both can be arranged slightly apart from the center of the center bracket (223).

[0122] In order to prevent the rotating plate (226) from being rotated unintentionally, an elastic washer (224) interposed between the rotating plate (226) and the center bracket (223) may be further included. The elastic washer (224) is a ring-shaped member having elasticity in the thickness direction and may be positioned between the rotating plate (226) and the head (2234) of the center bracket (223) as illustrated in FIGS. 5 and 11.

[0123] The center bracket (223) may include a head (2234) with a wide diameter at the rear end, and the elastic washer (224) is pressed when a force is applied in a direction that separates the rotation plate (226) and the center bracket (223) and the user holds the stand leg (210) and rotates it, thereby forming a space between the rotation plate (226) and the head (2234) of the center bracket (223) and allowing rotation.

[0124] When the force to rotate is removed, the elastic washer (224) can restrict the rotation of the rotation plate (226) by pressing the rotation plate (226) toward the base plate (221). Since the stand must be stably fixed to stably fix the main body (100), the elastic washer (224) can play a role in fixing the position of the rotation plate (226).

[0125] FIG. 12 and FIG. 13 are drawings illustrating the rotation of the swivel unit (220) of the display device (10) according to one embodiment of the present invention. The drawings are views of the swivel unit (220) as seen from the back with the swivel cover (225) removed. FIG. 12 illustrates the swivel unit (220) in a vertically mounted state as in FIG. 2, and FIG. 13 illustrates the swivel unit (220) in a horizontally mounted state as in FIG. 3.

[0126] The swivel unit (220) of the present embodiment may include an auxiliary plate (227) fastened to the back surface of the rotation plate (226). The auxiliary plate (227) may include a swivel stopper (228) protruding toward the back surface of the fixing ring (222).

[0127] The fixed ring (222) may include an angle limiting protrusion (2228) to limit the range of motion of the swivel stopper (228). The angle limiting protrusions (2228) include a pair as illustrated in FIG. 12, and the swivel stopper (228) can move between the pair of angle limiting protrusions (2228). That is, the range of rotation of the auxiliary plate (227) and the rotation plate (226) is limited, and the swivel stand (200) can rotate within a range of 90°.

[0128] The swivel stopper (228) must be fixed at a position where it comes into contact with the angle limiting protrusion (2228), i.e., at a position as shown in FIGS. 12 and 13, so that the main body (100) can be stably placed in a state as shown in FIGS. 2 and 3.

[0129] The elastic washer (224) described above presses the rotation plate (226) to limit rotation, but since a state in which the force of the main body (100) is supported requires more fixing force, a stop spring (229) may be included. The stop spring (229) may be arranged to overlap the swivel stopper (228) when the swivel stopper (228) reaches a position where it comes into contact with the angle limiting projection (2228).

[0130] The stop spring (229) may be protruded in a hook shape to be caught by a protrusion protruding from the front of the swivel stopper (228). Since the swivel stopper (228) is caught by the stop spring (229) and its rotation is restricted, the rotation of the swivel plate (226) can also be restricted. When the user holds the stand leg (210) and rotates it, the stop spring (229) may be deformed, causing the swivel stopper (228) to be separated from the stop spring (229).

[0131] Fig. 14 is a drawing illustrating a stand locking device of a display device (10) according to one embodiment of the present invention. The swivel stand (200) can secure the stand leg (210) so that it is not pulled out while stored in the stand mounting portion (111).

[0132] As shown in (a) of Fig. 14, a locking lever (2411) that is inserted and removed from the side of the stand mounting portion (111) may be included. The locking lever (2411) is inserted into a locking groove (2415) formed on the side of the first leg (211) and can fix the stand leg (210) to the stand mounting portion (111).

[0133] By moving (⑥) the lock switch (2412) exposed on the back of the main body (100), the lock lever (2411) can be withdrawn from the lock groove (2415), and then the stand leg (210) can be withdrawn from the stand mounting portion (111). A spring (2413) that presses the lock lever (2411) toward the lock groove (2415) so that the lock lever (2411) can be maintained in a state of being inserted into the lock groove (2415) may be further included.

[0134] Another locking method may utilize the push latch (2432) illustrated in (b) of FIG. 14. The push latch (2432) located on the stand mounting portion (111) is engaged with the latch projection (2431) formed on the second leg (212), and when the user presses the stand leg (210), the push latch (2432) and the latch projection (2431) are engaged, and when the user presses again, the push latch (2432) releases the latch projection (2431), allowing the stand leg (210) to be separated from the stand mounting portion (111).

[0135] The stand mounting portion (111) of the present embodiment does not extend to the end of the main body (100), so that a groove is required in the side wall of the stand mounting portion (111) to hold the side of the stand leg (210) by inserting a finger in order to pull out the stand. However, since such a groove may cause a foreign feeling on the back surface, the display device (10) of the present invention may be provided with a pop-up structure for the stand leg (210).

[0136] Fig. 15 is a drawing illustrating a pop-up spring of a display device (10) according to one embodiment of the present invention. The pop-up spring that presses the stand leg (210) in the rear direction at the stand mounting portion (111) may use a torsion spring.

[0137] As shown in (a) of Fig. 15, one end of a torsion spring wound around a hinge shaft (231) can be fixed to a swivel unit (220) and the other end can be arranged to pressurize a stand leg (210).

[0138] As shown in (b) of Fig. 15, a torsion spring can be placed on one side wall of the stand mounting portion (111). One side of the torsion spring can be fixed to the main body (100), and the other side can be placed in contact with the front of the stand leg (210) so as to press the stand leg (210) toward the back.

[0139] The torsion spring provides a force that presses the stand leg (210) in the rearward direction, and when the stand lock device of FIG. 14 is released, the stand leg (210) can protrude in the rearward direction from the stand mounting portion (111).

[0140] Fig. 16 is a perspective view of the back (110) of a display device (10) according to another embodiment of the present invention. The swivel stand (200) of this embodiment is longer and wider than the embodiment described above.

[0141] Since the stand leg (210) of the present embodiment extends to the longitudinal end of the main body (100), the end of the stand mounting portion (111) can also be opened. The user can hold the second end of the stand leg (210) and pull the stand leg (210) out of the stand mounting portion (111), so that the swivel stand (200) of the present embodiment can omit the pop-up spring as shown in FIG. 15.

[0142] The wider the stand leg (210), the more stable the fastening becomes. If the stand leg (210) is long, the sliding structure for adjusting the length, as in the aforementioned embodiment, is unnecessary, thereby simplifying the structure of the stand.

[0143] Figure 17 is an exploded perspective view of a display device (10) according to another embodiment of the present invention.

[0144] The stand foot (215) (215) located at the end of the stand leg (210) of the present invention can be configured by combining a material having high friction to the second end of the stand leg (210). The stand leg (210) can be prevented from being separated from the stand mounting portion (111) by the frictional force of the stand foot (215).

[0145] Fig. 18 is a BB cross-sectional view of Fig. 16, illustrating a stand hinge (230). Fig. 19 is a drawing illustrating a stand hinge (230) of a display device (10) according to another embodiment of the present invention.

[0146] The stand leg (210) of the present invention may be arranged such that the shaft coupling portion (2115) into which the hinge shaft (231) is inserted protrudes toward the front of the stand leg (210). That is, the shaft hole (2116) of the shaft coupling portion (2115) may be positioned forward of the center of the thickness direction of the stand leg (210).

[0147] The stand leg (210) of the present embodiment has a wide width (a) so that the widthwise length (b) of the stand shaft connecting portion (2115) is shorter than the width of the stand leg (210). In order for the hinge shaft (231) to be connected to the shaft portion of the hinge bracket (233) on both sides of the shaft hole (2116), the shaft connecting portion (2115) has a shape that protrudes forward of the stand leg (210).

[0148] The central axis of the hinge shaft (231) moves toward the front of the stand leg (210) more than in the embodiment described above, and the distance (r) from the hinge shaft (231) to the first end (216) of the stand leg (210) becomes longer. That is, when the stand hinge (230) rotates, a problem occurs in which the rotation radius (r) of the first end (216) of the rotation increases.

[0149] In addition, since the length of the stand leg (210) is long, when supporting the back surface (110) of the main body in a horizontal position, the stand leg (210) must be spread out at a large angle. As illustrated in Fig. 18, the rotation angle (α) of the stand hinge (230) can rotate by 50° or more.

[0150] That is, it is necessary to sufficiently secure the rotation radius size of the first end (216) of the stand leg (210) and the rotation angle of the stand hinge (230) according to the position in the thickness direction of the shaft hole. In order to prevent interference between the first end (216) of the stand leg (210) of the present embodiment and the swivel unit (220), it is necessary to delete the configuration that blocks the portion of the stand leg (210) adjacent to the first end (216).

[0151] The stand hinge (230) is fastened to the swivel unit (220) and rotates together with the swivel unit (220), so it must have a size that does not protrude from the swivel unit (220). Since the circular swivel unit (220) becomes narrower as it moves away from the center, the shaft coupling portion (2115) of the wide stand leg (210) must be positioned close to the center of the swivel unit (220). Therefore, as illustrated in FIG. 18, the shaft coupling portion (2115) is positioned close to the center bracket (223) of the swivel unit (220).

[0152] In addition, when the hinge bracket (233) that fixes the hinge shaft (231) as in the above-described embodiment is positioned to face the first end (216) of the stand leg (210), it is difficult to secure space for the first end (216) to rotate.

[0153] Accordingly, the stand hinge (230) of the present embodiment may have the position of the joint of the hinge bracket (233) positioned in the opposite direction from the first end of the stand leg (210) from the hinge shaft (231), i.e., in the direction of the second end. As illustrated in Fig. 19, the hinge bracket (233) may be fastened to the rotation plate (226) at the front of the stand leg (210).

[0154] In the embodiment of Fig. 4, the rotating plate (226) omits the portion positioned in front of the stand leg (210) and places the leg stopper (213) of the stand leg (210). However, in this embodiment, the leg stopper (213) is unnecessary, so the rotating plate (226) can be positioned in the portion overlapping the stand leg (210). As illustrated in Fig. 17, the rotating plate (226) may have a circular shape including a hole in a space in which the shaft coupling portion (2115) is inserted and rotates.

[0155] Fig. 20 is a rear view of a swivel unit (220) of a display device (10) according to another embodiment of the present invention. In this embodiment, the auxiliary plate (227) is omitted, and the protrusion (2268) protruding from the rotation plate (226) can limit the rotation of the rotation plate (226) when it comes into contact with the angle limiting protrusion (2228) of the fixing ring (222).

[0156] In this embodiment, the aforementioned swivel stopper (228) can protrude from the center bracket (223) and the stop spring (229) can be positioned on the rotation plate (226).

[0157] The swivel stopper (228) protrudes from the non-rotating center bracket (223) and can move in an arch relative to the rotating plate. A stop spring (229) can be placed on the back surface of the rotating plate (226) along the movement path of the swivel stopper (228).

[0158] As shown in Fig. 20, the stop spring (229) may be configured as an integral part in an arch shape, or may be placed at the position of each swivel stopper (228) when the swivel stand (200) is in the first state and the second state.

[0159] FIG. 21 is a drawing showing a swivel stopper (228) and a stop spring (229) of a display device (10) according to another embodiment of the present invention.

[0160] The stop spring (229) protrudes backward at a position overlapping the swivel stopper (228) in the first and second states, and the protrusion protruding in front of the swivel stopper (228) is caught by the stop spring (229) and rotation is restricted.

[0161] In the embodiment of Fig. 12, the rotating configuration was a swivel stopper (228), but in the embodiment of Fig. 21, a stop spring (229) rotates. Since the positions of the stop spring (229) and the swivel stopper (228) are relative, even if configured as in this embodiment, the same effect as the configuration described above can be obtained.

[0162] As seen above, the display device (10) of the present invention has the advantage of excellent portability as it can accommodate a stand on the back.

[0163] The display device (10) of the present invention can be stably mounted by changing the mounting direction of the main body (100).

[0164] The display device (10) of the present invention can adjust the length of the stand leg (210), so that the display device (10) can be placed at a desired angle.

[0165] The above detailed description should not be construed as limiting in any respect and should be considered illustrative only. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
