Description

Technical Field

[0001] The present invention relates to an introducible and extroducible display device and a vehicle equipped with the display device. Background Technology

[0002] A vehicle is a device that allows passengers to travel in the desired direction. In recent years, it has been equipped not only with an engine and wheels for simple driving, but also with various devices for the safety and convenience of the user.

[0003] Vehicle convenience features include functions such as providing infotainment, supporting partial autonomous driving, or helping the driver ensure visibility in areas such as nighttime visibility or blind spots. These are all related to driver convenience. Examples include features such as adaptive cruise control (ACC), smart parking assist system (SPAS), night vision (NV), head-up display (HUD), around view monitor (AVM), and adaptive headlight system (AHS).

[0004] In addition, vehicle safety features are technologies that ensure the safety of the driver and / or pedestrians, including lane departure warning system (LDWS), lane keeping assist system (LKAS), and automatic emergency braking (AEB).

[0005] The instrument cluster, used to provide information about the vehicle's status, is trending towards being digitized and replaced by display devices. Additionally, the center fascia, located between the driver and passenger seats, which previously only had output functions, is now being used as an input device with added touch functionality.

[0006] The display not only outputs information but also has a touch sensor to enable simultaneous touch input, thus functioning as both an output and input unit. Furthermore, the size of display devices used in vehicles is gradually increasing.

[0007] While increasing the size of the display panel is certainly good for ease of use, it will take up a lot of space when not in use. If it occupies too much space when turned off, it may become a factor that disrupts the interior design of the vehicle.

[0008] There is a need for a display device that can be brought out only when needed to provide a sufficiently large screen without compromising the vehicle’s interior design elements. Summary of the Invention

[0048] Figure 1 This is a diagram showing the exterior of a vehicle according to an embodiment of the present invention. Figure 2 This is a diagram showing the interior of a vehicle according to an embodiment of the present invention.

[0049] The vehicle may include wheels 70 that rotate using a power source and may consist of a front-opening glass panel that allows a user inside to see ahead. The vehicle's interior may include a steering input 51 for adjusting the vehicle's direction of travel, and an acceleration input 53 and a braking input 57 for controlling the vehicle's speed.

[0050] The steering input device 51 can receive the driving direction input of the vehicle 10 from the user. The steering input device 51 is preferably configured as a steering wheel so that steering input can be performed by rotation. According to an embodiment, the steering input device may also be configured as a touch screen, touchpad, or button.

[0051] Acceleration input device 50 can receive input from the user for accelerating the vehicle 10. Braking input device 57 can receive input from the user for decelerating the vehicle 10. Acceleration input device 53 and braking input device 57 are preferably configured as pedals. According to an embodiment, the acceleration input device or braking input device may also be configured as a touch screen, touchpad, or button.

[0052] The vehicle can operate in manual mode, where the user controls the vehicle's direction of travel by operating the steering, acceleration, and braking input devices. Alternatively, it can switch to autonomous driving mode based on information and data provided by external devices and information about surrounding objects, allowing the operating system to drive the vehicle automatically without user intervention.

[0053] A communication device may be included to receive information and data from an external device. A communication device is a means for communicating with an external device. Here, the external device may be another vehicle, a mobile terminal, or a server.

[0054] A communication device may include at least one of a transmitting antenna, a receiving antenna, a radio frequency (RF) circuit capable of implementing various communication protocols, and an RF element to perform communication.

[0055] The communication device may include a short-range communication unit, a location information unit, a V2X communication unit, an optical communication unit, a broadcast transmitter / receiver unit, and a processor.

[0056] The vehicle may include an object detection device to obtain information about surrounding objects.

[0057] Objects can include lanes, other vehicles, pedestrians, two-wheeled vehicles, traffic signals, light, roads, structures, speed bumps, terrain features, animals, etc. Object detection devices can include cameras, radar, lidar, ultrasonic sensors, and infrared sensors.

[0058] The operating system is the system that controls various operations of the vehicle. It can operate in autonomous driving mode, and in manual mode, the operating system can assist the user's operation.

[0059] The operating system may include a processor and may control the power source and wheels 70 based on information received from the object detection device and the communication device.

[0060] The vehicle may include a user interface device to communicate with the user. The user interface device can receive user input and provide the user with information generated in the vehicle 10.

[0061] The user interface device may include an input unit, an internal camera, a biometric detection unit, an output unit 25, and a processor. According to embodiments, the user interface device may also include other components besides those described, or may exclude some of the described components.

[0062] Output unit 25 is used to generate outputs related to vision, hearing, or touch. Output unit 25 may include at least one of a display device and a sound output unit, and may display graphics corresponding to various information via the display device. The display device may include a display panel, which may include one of a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), and a flexible display.

[0063] As display panels become thinner and more diverse in form, the size of the output unit can be increased, and its placement can be varied. Furthermore, the display device can be stacked with a touch sensor that recognizes touch, allowing the output unit to also function as an input unit.

[0064] Traditionally, display devices can be installed in various locations such as the steering wheel, instrument panel, seats, pillars, doors, center console, headliner, sun visors, and windshield. Consequently, the size of display devices used in vehicles has gradually increased.

[0065] While increasing the size of the display panel 410 is certainly good for ease of use, it will take up a lot of space when not in use. If it occupies too much space when turned off, it may become a factor that disrupts the interior design of the vehicle.

[0066] There is a need for a display device that can be brought out only when needed to provide a sufficiently large screen without compromising the vehicle’s interior design elements.

[0067] Accordingly, the present invention provides a display device that can be extended when needed and retracted when not needed to reduce the size of the exposed screen. The display device of the present invention is described based on its installation in a vehicle, but it can also be installed in mobile vehicles other than vehicles and in fixed locations.

[0068] Figure 3 This is a perspective view showing a first state of a display device 1000 according to an embodiment of the present invention. Figure 4 This is a perspective view showing a second state of a display device 1000 according to an embodiment of the present invention.

[0069] Figure 5 This is a perspective view showing a third state of a display device 1000 according to an embodiment of the present invention. Figures 3 to 5 This is a three-dimensional view taken from an angle above. The lower left side of the image is the front, which will be referred to as the first direction below.

[0070] The display device 1000 of the present invention may include a base module 100 fixed to a vehicle or the like and a display module 400 movable on the base module 100. The display module 400 may include a flexible display panel 410, and may be as follows: Figure 4 and Figure 5 It bends and deforms as shown.

[0071] The display module 400 may include a first flat portion 401 and a second flat portion 402 that remain flat, and may include a variable portion 403 located between them. The flat portion located in the first direction is referred to as the first flat portion 401, and the flat portion located in the opposite direction is referred to as the second flat portion 402.

[0072] To realize the variable part 403, the display module 400 can utilize a flexible display panel 410 that is capable of bending and deforming, such as an organic light-emitting diode panel. The distinction between the first planar part 401, the second planar part 402, and the variable part 403 can be determined using the back structure of the display panel 410.

[0073] The first planar portion 401 and the second planar portion 402 may include a flat back support structure to secure the drive portion or guide structure that provides power for driving the display module 400. For example... Figure 3 As shown, the variable part 403 is supported by a plurality of bent rods 423 extending in the horizontal direction on the back of the display panel 410, and the curvature of the variable part 403 can change with the angle between the bent rods 423.

[0074] It may include a housing 600 for storing the display device 1000 (see reference). Figure 7 The housing 600 may have a panel opening 610 formed in the first direction of the display device 1000, which allows the display module 400 to pass through. Figure 7 The display device 1000 of the present invention can be introduced and withdrawn through the panel opening 610, and selectively exposed to the user.

[0075] Figure 3 The first state shown can be a state where the display module 400 is housed inside the housing and not in use. Figure 4 The second state shown is a state in which only a portion of the display module 400, including the first flat portion 401, is exposed through the opening 610. Unlike the first state, the first flat portion 401 faces downward.

[0076] Here, the direction below can be referred to as the second direction to distinguish it from the first direction mentioned above. The second direction can be at an angle close to 90° to the first direction, but it is not necessarily limited to this. It refers to the direction that is bent in a direction different from the first direction.

[0077] The second state is a state in which the angle between the first planar portion 401 and the second planar portion 402 further decreases from the first state. As the variable portion 403 bends and deforms with a predetermined curvature, the display module 400 can simultaneously move in the first direction to be led out through the panel opening 610.

[0078] The third state is when the display module 400 is further extended from the second state, thus further increasing the area in the second direction. The second state, in which only a portion of the display module 400 is extended, can be called half-screen, and the state in which the display module 400 is extended to the maximum extent can be called full-screen. Figure 6This is an exploded perspective view of a display device 1000 according to an embodiment of the present invention. The display device 1000 of the present invention may include a base module 100, a bending module 200, a sliding module 300, and a display module 400.

[0079] The base module 100 can be fixed to a vehicle or the like, and includes a guide wall 110. The guide wall 110 has tracks 120 and 130 formed thereon for guiding the movement of the bending module 200 and the sliding module 300, which serve as drive units. There may be only one guide wall 110, or there may be a pair of guide walls arranged separately in the lateral direction, so that the display module 400 can move while maintaining left-right balance.

[0080] The base plate 150 connecting the guide walls 110 can form the bottom surface of the display device 1000, and the first drive part 210 of the bending module 200 can be placed on the base plate 150.

[0081] The tracks 120 and 130 formed on the guide wall 110 may include a plurality of tracks, and the guide wall 110 may be composed of a first guide wall 111 and a second guide wall 112, so that the plurality of tracks 120 and 130 are formed so as not to overlap each other.

[0082] The display module 400 may include a bending module 200 and a sliding module 300 to switch from a first state to a second state and from the second state to a third state, or vice versa.

[0083] In order to transition from the first state to the second state, the bending module 200 pushes the first planar portion 401 of the display module 400 in a first direction while changing the angle of the first planar portion 401 to guide the bending deformation of the variable portion 403. The bending module 200 may include a rear plate 240, a rotating arm 230, a bending link 220, and a first drive unit 210.

[0084] The rear plate 240 can be coupled to the back of the first flat portion 401 of the display module 400. The rear plate 240 is coupled to the first flat portion 401 through a pin groove and transmits the driving force of the bending module 200 to the first flat portion 401 without hindering the driving of the sliding module 300.

[0085] When the bending module 200 is driven, the first flat portion 401 can change its configuration direction. When the sliding module 300 is driven, the display module 400 can slide independently of the rear plate 240, thereby changing from the second state to the third state.

[0086] The rotating arm 230 can form a predetermined angle with the rear plate 240 and extend. If the rotating arm 230 rotates and changes its configuration, the configuration of the rear plate 240 changes, thereby changing from a first state to a second state.

[0087] The rotating arm 230 may include a plurality of curved guide pins. A curved guide pin is a protrusion that inserts into and moves along a curved guide rail 120 formed in the guide wall 110. Rotatable bearings or rollers may be included on the outer surface of the curved guide pin to facilitate movement along the curved guide rail 120.

[0088] The rotating arm 230 can be fastened to one end of the bending link 220 so that it can rotate via the rotating shaft 250. The rotating arm 230 can receive the power of the first drive unit 210 through the bending link 220, rotate independently of the bending link 220, and guide the bending deformation of the variable part 403.

[0089] The first drive unit 210 can be fixed to the base module 100, see reference. Figure 10 The first drive unit 210 may consist of a first motor 211, a first gear set 212, a first ball screw 213, and a first drive nut 214. It may include a first gear set that transmits the rotational force of the first motor 211 to the first ball screw 213. If the first ball screw 213, extending in a first direction, rotates, the first drive nut 214, through which the first ball screw 213 passes, can move along the extension direction of the first ball screw 213 and change its position in the first direction.

[0090] The first drive nut 214 can be fastened to the drive frame 225, which may include a second sliding pin 270 fastened to a sliding track 130 formed in the guide wall 110, so that it can be driven only in the first direction.

[0091] The sliding track 130 for the movement of the second sliding pin 270 can be configured to move along the same sliding track 130 as the first sliding pin 370 which slides in the first direction of the guide sliding module 300.

[0092] The bending link 220 provides the rotating arm 230 with a driving force to move in a first direction or a third direction in the opposite direction to the first drive unit 210. The rotating arm 230 can convert the driving force provided by the first drive unit 210 in the linear direction into rotational motion by bending the guide rail 120 and the guide pin.

[0093] The sliding module 300 may include a first sliding pin 370 that moves along a sliding track 130. The sliding track 130 may be formed on the second guide wall 112 such that the path of the sliding pin 370 does not overlap with the drive of the rotating arm 230.

[0094] When the sliding module 300 transitions from the second state to the third state, it can push the second planar portion 402 of the display module 400 toward the first direction and move the first planar portion 401 further toward the second direction, thereby increasing the area of ​​the exposed display module 400.

[0095] The sliding module 300 may include: a sliding frame 320, which is fastened to the bending link 220 of the bending module 200 via a rotation shaft 250; and a second drive unit 310, which is fixed to the sliding frame 320.

[0096] The display panel 410 is composed of a first flat portion 401, a second flat portion 402 and a variable portion 403 located between them. The bending module 200 provides power to the first flat portion 401 and the sliding module 300 provides power to the second flat portion 402.

[0097] The panel cover 420 located on the back of the flexible display panel 410 may be composed of flat covers 421 and 422 covering the back of the first flat portion 401 and the second flat portion 402, and a plurality of bent rods 423 located on the back of the variable portion 403 and supporting it.

[0098] The variable portion 403 can be supported on the back of the display panel 410 by a plurality of bent rods 423 extending in the horizontal direction, and the curvature of the variable portion 403 can change with the angle between the bent rods 423. The bent rods 423 can be connected to adjacent bent rods 423 using a flexible material.

[0099] Figure 7 This is a perspective view showing an embodiment of a display device 1000 installed inside a vehicle according to an embodiment of the present invention.

[0100] The display device 1000 of the present invention may include a housing 600 that houses a display module 400 and driving components (100 to 300). The display module 400 may be introduced and withdrawn between the interior and exterior of the housing 600. In order to introduce and withdraw the display module 400, the housing 600 may include a panel opening 610 that extends elongated in the horizontal direction.

[0101] When the display module 400 is extended, the first direction D1 of the drive frame 225 can be towards the front of the user, and the third direction D3 and the fourth direction D4 can be perpendicular to the lower and upper sides of the first direction, respectively, or the first direction D1 can be upward and the third direction can extend horizontally. Depending on the configuration of the display module 400, the direction of the panel opening 610 can also be changed.

[0102] For ease of explanation, the following description will be based on a display device 1000 mounted in a vehicle. The housing of the display device 1000 mounted in the vehicle may be a dashboard 600 located in front of the driver.

[0103] The display device 1000 can be introduced and extended through the panel opening 610 formed in the instrument panel 600. The display device 1000 can be located inside the instrument panel 600 in a first state, such as... Figure 6As shown in (a), it cannot be seen by the user and can be brought out and transformed into, as shown in the second and third states. Figure 6 The state shown in (b).

[0104] In the display device 1000 of the present invention, such as Figure 3 As shown, in the first state, the display module 400 can be in a planar state. To transition to the second state, the variable part 403 can be bent, and the display module 400 can be extended forward, protruding to the outside through the panel opening 610 of the instrument panel 600. In the third state, the display module 400 is driven, the bending position of the variable part 403 changes, and the area of ​​the display module 400 exposed to the front increases.

[0105] The display device 1000 of the present invention is extended by bending of the variable part, and the back plate 240 and the like are combined with the back of the display module 400 in order to realize the sliding drive of the display device 1000. Therefore, the length of the panel opening 610 in the thickness direction needs to be set to be large.

[0106] Figure 8 This is a diagram showing the location of the door and panel openings 610 of a vehicle dashboard 600 according to an embodiment of the present invention. Figure 8 As shown in (a), the thickness of the panel opening 610 is greater than that of the display module 400, which could result in the drive structure behind the display device 1000 and the interior of the instrument panel 600 being visible.

[0107] Therefore, as Figure 8 As shown in (b), the present invention may include a door module 500 having a door panel 510 covering a panel opening 610. The door panel 510 of the present invention may cover only a portion of the panel opening 610.

[0108] Since the display module 400 and the panel opening 610 need to be aligned in order to enable the introduction and exit of the display module 400, the first direction D1 end of the display module 400 can also be located in the panel opening 610 in the first state.

[0109] In this embodiment, the door module 500 can be configured to cover only a portion of the panel opening 610, and the display module 400 can penetrate the panel opening 610 in a state of being inserted into the panel opening 610.

[0110] The panel opening 610 may include a first opening 611 for the display module 400 to pass through and a second opening 612 located on the third side of the first opening 611. The second opening 612 may allow the rear plate 240, the bending link, and the hinge arm located on the back of the display module 400 to pass through.

[0111] The size of the first opening 611 can correspond to the width and thickness of the display module 400. The width of the second opening 612 can be the same as the width of the first opening 611, but it can also have a width corresponding to the width of the rear panel 240. The sizes of the first opening 611 and the second opening 612 can be different from each other. For ease of explanation, the description is divided into the first opening 611 and the second opening 612, but the first opening 611 and the second opening 612 are connected to form one opening (panel opening 610).

[0112] The door panel 510 is not limited to this embodiment, and the door module 500 may also be in the form of covering the entire panel opening 610.

[0113] In addition to the dashboard 600, the display device 1000 of the present invention can also be installed in other devices. In this case, the housing that forms the appearance of the display device 1000 includes a panel opening 610 that is opened and closed by the door panel 510, but may have a different shape than the dashboard 600.

[0114] The door module 500 may include a door drive unit that moves the door panel 510 in a third direction to open a second opening 612 of the panel opening 610. The door drive unit may use a motor or the like to move the door panel 510 in the vertical direction, but adding an additional motor may increase costs and increase the size of the display device 1000.

[0115] In addition, the door drive unit needs to be driven at the same time as the drive display module 400, so it needs to operate synchronously with the drive unit 210 of the drive display module 400.

[0116] The present invention can receive power from the first drive unit of the mobile display module 400 and drive the door panel 510 without the need for an additional motor, thereby reducing the size and synchronizing with the drive unit 210 of the display device 1000.

[0117] Figure 9 This is a perspective view showing a gate module 500 of a display device 1000 according to an embodiment of the present invention. Figure 10 This is an exploded perspective view showing a gate module 500 of a display device 1000 according to an embodiment of the present invention.

[0118] The door module 500 of the present invention may include a door panel 510, a door rod 520, and a door guide 530 for guiding the door rod 520.

[0119] like Figure 9 As shown, the door guide 530 is formed on the drive frame 225. In this embodiment, the door guide 530 is formed on the lower part of the side wall of the drive frame 225. It can also be provided on the side wall of the drive frame 225 in the form of a track.

[0120] The door guide 530 may include: an inclined portion 531 that protrudes from the end of the first direction D1 toward a third direction (the lower side in the figure); and a straight portion 534 that extends horizontally from the upper end of the inclined portion 531 toward a second direction.

[0121] The doorpost 520 may include a first arm 521 extending along the second direction D2 and a second arm 522 extending along the second direction D2. The first arm 521 and the second arm 522 are rotatably fixed to the rod fixing portion 540 fixed to the base module 100 by means of a rod shaft 525. The first arm 521 and the second arm 522 may form a straight line, or they may be arranged as follows: Figure 9 The shape shown is a V-shape formed by bending.

[0122] The end of the first arm 521 may include a first rod roller 523 that moves along the door guide 530. When the first rod roller 523 is located in the inclined portion 531, the end of the second arm 522 may move in the opposite direction to the movement of the first rod roller 523.

[0123] The end of the second arm 522 can be connected to and hinged to the door panel 510, but the end of the second arm 522 moves in an arc about the rod axis 525, and may therefore include a second rod roller 524 that can slide on the door panel 510 to transmit vertical force only to the door panel 510.

[0124] The second roller 524 may include a rear door support 512 that protrudes horizontally from the door panel 510 in the second direction D2. The second roller 524 moves along the bottom surface of the rear door support 512 in the first direction D1 or the second direction D2. During the movement of the second arm 522, the vertical movement is transmitted to the door panel 510 for drive, and the horizontal movement guides the positional change on the rear support 512.

[0125] A pair of door rods 520 can be connected to the left and right sides of the door panel 510. The first rod rollers 523 move along the door guides 530 formed in the drive frame 225, so they can move synchronously and simultaneously.

[0126] In this embodiment, the drive frame 225 with the door guide 530 moves in the first direction and causes the display module 400 to move when the display module 400 is led out. Therefore, the movement of the door panel 510 can be synchronized with the movement of the display module 400.

[0127] Figures 11 to 14 This is a side view illustrating the driving process of a display device 1000 according to an embodiment of the present invention. Hereinafter, reference will be made to... Figures 11 to 14 Based on the movement of the display module 400 and the drive frame 225, the driving mode of the gate module is explained in stages.

[0128] Figure 11 The first state of the display module 400 configured as a planar state is shown. Figure 14 This illustrates a second state in which the variable portion 403 is bent so that the first planar portion 401 of the display module 400 faces forward. Figure 12 and Figure 13 The state of gate module 500 during the transition from the first state to the second state is shown.

[0129] like Figure 11 As shown, in the first state, the display module 400 is located inside the housing (instrument panel 600), and the door panel 510 covers the panel opening 610.

[0130] The drive frame 225 is located in the second direction D2, and the first rod roller 523 of the door rod 520 is located at the end of the door guide 530 in the first direction D1. The end of the door guide 530 in the first direction D1 protrudes in the third direction, so that the first arm 521 of the door rod 520 is pressed down, and the second rod roller 524 located at the end of the second arm 522 pushes the door panel 510 upward and supports it.

[0131] like Figure 11 As shown, the length of the first arm 521 of the door rod 520 can be greater than the length of the second arm 522. This is because the protrusion of the inclined portion 531 of the door guide 530 is limited, thus allowing the door panel 510 to move more than the first arm 521.

[0132] As the first motor 211 starts operating, the drive frame 225 slides in the first direction D1. Figure 12 As shown, the first rod roller 523 moves from the inclined portion 531 of the door guide 530 to the straight portion 534, the end of the first arm 521 moves upward (D4), and the second end moves downward (D3).

[0133] It may also include a door elastic portion 550 that pulls the door panel 510 toward a third party, D3. The door elastic portion 550 provides elasticity in the direction that pulls the door panel 510 toward a third party and toward the opening of the panel opening 610. The door rod 520 supports the door panel 510 in the direction that resists the elasticity of the door elastic portion 550, and then, when the drive frame 225 moves in the first direction D1, as... Figure 12 As shown, the door panel 510 will move to the third direction D3 due to the elasticity of the door elastic part 550.

[0134] When the door guide 530 is in the form of a track, the movement of the door rod 520 is determined according to the height of the door guide 530. However, in this embodiment, the door guide 530 is formed on the bottom surface of the drive frame 225 and is in the form of an open bottom.

[0135] Therefore, the end of the second arm 522 of the door bar 520 can be pressed down by the force of the door elastic part 550 pressing the door panel 510 in a third direction, and the first rod roller 523 of the first arm 521 can be attached to the door guide 530 and move according to the height of the door guide 530.

[0136] Reference Figure 12 A curved surface 533 may be included between the inclined portion 531 and the straight portion 534 to ensure stable movement of the first rod roller 523. The end of the inclined portion 531 may include a locking portion 531 that is bent in the horizontal direction to stably fix the door rod 520, so that the door panel 510 can be kept closed in the first state.

[0137] The first roller 523 disengages from the locking part 531 and moves through the inclined part 531 to the straight part 534 when the drive frame 225 begins to move in the first direction D1. The inclined part 531 has a large slope, and its horizontal length d can be longer than its vertical length c.

[0138] The door panel 510 needs to be moved in a third direction before it comes into contact with the rear plate 240 through the second opening 612 covered by the door panel 510. Figure 11 In the first state, the length d of the first direction D1 of the inclined portion 531 can be equal to or less than the distance b between the door panel 510 and the back panel 240.

[0139] like Figure 13 As the variable portion 403 of the display module 400 bends, the display module 400 can be exposed to the outside of the instrument panel 600, and the first rod roller 523 can move along the straight portion 534. However, the length of the drive frame 225 is limited, therefore... Figure 14 The first roller 523 can be separated from the door guide 530.

[0140] When the display module 400 transitions from the second state to the first state, the lower side of the door guide 530 is open, so the first door bar 520 can easily reconnect with the straight portion 534 of the door guide 530 and move along the door guide 530.

[0141] However, if the first roller 523 disengages from the door guide 530, and the door elastic part 550 pulls the door panel 510 to a position greater than... Figure 13 If the position is further down, the first roller 523 may have difficulty re-entering the door guide 530.

[0142] Therefore, it may also include a door stop (not shown) located at the lower end of the door panel 510 to limit the movement distance of the door panel 510 in the third direction D3.

[0143] As described above, the display device 1000 of the present invention can extend the display module 400 when needed, and store the display module 400 when not in use.

[0144] In addition, the display device 1000 of the present invention can cover the drive unit so that it is not exposed to the outside when stored, so as not to affect the aesthetics and to prevent foreign matter from flowing in.

[0145] In addition, the display device 1000 of the present invention does not require an additional motor for the gate module 500, thus having the advantages of simple structure and synchronization with the movement of the display module 400.

[0146] The detailed description above should not be construed as restrictive in all respects, but should be considered exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
