Description

Technical Field

[0001] The present invention relates to a deformable display device, and more specifically, to a display device that can be repositioned and retracted or extended when needed. Background Technology

[0002] As a device that allows passengers to travel in a desired direction, vehicles have, in recent years, been equipped not only with engines and wheels for driving, but also with various devices for user safety and convenience.

[0003] Vehicle convenience features include infotainment functions, support for partial autonomous driving, and driver assistance features such as improved visibility at night or in blind spots. Examples include adaptive cruise control (ACC), smart parking assist system (SPAS), night vision (NV), head-up display (HUD), surround view monitor (AVM), and adaptive headlight system (AHS).

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

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

[0006] Displays can not only simply output information, but also have touch sensors for touch input, thus functioning as both an output and input unit. As a result, the size of display devices used in vehicles is gradually increasing.

[0007] While increasing the size of the display panel can improve ease of use, it can also take up a large area when not in use. If it occupies a large area when turned off, it could become a factor that disrupts the vehicle's interior design.

[0008] Therefore, there is a need for display devices that can be deployed only when necessary, providing a sufficiently large screen without compromising the vehicle's interior design elements. Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] The purpose of this invention is to provide a retractable display device that can be extended when needed and retracted when not needed, thereby reducing the size of the exposed screen.

[0060] 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.

[0061] The vehicle may include wheels 70 that rotate using a power source, and the front may consist of open glass to allow a user inside the vehicle to see what is ahead. The interior of the vehicle may include a steering input 51 for adjusting the vehicle's direction of travel, an acceleration input 53 for controlling the vehicle's speed, and a braking input 57.

[0062] The steering input device 51 can receive driving direction input from the user of the vehicle 10. The steering input device 51 is preferably configured as a steering wheel so that steering input can be achieved by rotation. According to embodiments, the steering input device may also be configured as a touchscreen, touchpad, or button.

[0063] Acceleration input device 50 can receive input from a user for accelerating the vehicle 10. Braking input device 57 can receive input from a user for decelerating the vehicle 10. Acceleration input device 53 and braking input device 57 are preferably configured as pedals. According to embodiments, the acceleration input device or braking input device may also be configured as a touchscreen, touchpad, or button.

[0064] The vehicle can operate in manual mode, where the user controls the direction of the vehicle by operating the steering, acceleration, and braking input devices. It can also switch to autonomous driving mode based on information and data provided by external devices and information related to surrounding objects, so that the system can achieve autonomous driving without user operation.

[0065] 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.

[0066] The communication device may include at least one of a transmitting antenna, a receiving antenna, an RF (Radio Frequency) circuit capable of implementing various communication protocols, and an RF element to perform communication.

[0067] The communication device may include a short-range communication unit, a location information unit, a V2X (vehicle-to-everything) communication unit, an optical communication unit, a broadcast transceiver unit, and a processor.

[0068] The vehicle may include an object detection device to obtain information related to surrounding objects.

[0069] Objects can include lanes, other vehicles, pedestrians, two-wheeled vehicles, traffic signals, light, roads, structures, speed bumps, terrain features, and animals. Object detection devices can include cameras, radar, lidar, ultrasonic sensors, and infrared sensors.

[0070] The operating system, which controls various operations of the vehicle, can perform actions in autonomous driving mode, and in manual mode, it can assist the user in operation.

[0071] The operating system may include a processor that can control the power source and wheels 70 based on information received from the object detection device and the communication device.

[0072] 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 by the vehicle 10.

[0073] The user interface device may include an input unit, an internal camera 220, a biometric sensing 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 only a portion of the described components.

[0074] The output unit 25 is used to generate outputs related to vision, hearing, or touch. The output unit 25 may include at least one of a display device and an audio output unit, and can display graphics corresponding to various information via the display device. The display device may include a display panel comprising 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.

[0075] As display panels become thinner and more diverse in form, the size of the output section can be increased, and its placement can be varied. Furthermore, by layering the display device with a touch sensor that recognizes touch, the output section can simultaneously function as an input section.

[0076] Traditionally, display devices can be placed in input areas such as the steering wheel, dashboard, seats, pillar trim, doors, center console, headliner, sun visors, and windshield. Consequently, the size of display devices used in vehicles has been gradually increasing.

[0077] While increasing the size of the display panel 410 for ease of use is a good thing, it will occupy a large area when not in use. If it occupies too much area when turned off, it may become a factor that disrupts the interior design of the vehicle.

[0078] Therefore, there is a need for display devices that can be deployed only when needed, providing a sufficiently large screen without compromising the vehicle's interior design elements.

[0079] In response, the present invention provides a display device that can be extended when needed and retracted when not needed, thereby reducing the size of the exposed screen. The display device of the present invention is described based on a display device mounted in a vehicle, but it can also be installed in mobile vehicles or fixed locations.

[0080] 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.

[0081] 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 above at an angle. In the attached diagram, the lower left corner is the front. The front will be used as the primary direction for the following explanation.

[0082] 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, which can be, for example... Figure 4 and Figure 5 It bends and deforms like that.

[0083] 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 called the first flat portion 401, and the flat portion located in the opposite direction is called the second flat portion 402.

[0084] To realize the variable part 403, the display module 400 can utilize a flexible display panel 410 such as a bendable and deformable 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 by the back structure of the display panel 410.

[0085] The first planar portion 401 and the second planar portion 402 may include a flat back support structure for securing the drive portion or guide structure that provides the power required to drive the display module 400. The variable portion 403, as... Figure 3 As shown, the back of the display panel 410 is supported by a plurality of curved rods 423 extending in the horizontal direction. The curvature of the variable part 403 can change as the angle between the curved rods 423 changes.

[0086] It may include a housing 500 for storing the display device 1000 (see reference). Figure 12 The cover 500 may have a panel opening 510 in the first direction of the display device 1000, through which the display module 400 can pass. Figure 12 The display device 1000 of the present invention is introduced and extended through the panel opening 510, thereby selectively exposing it to the user.

[0087] Figure 3 The first state shown can be that the display module 400 is housed inside the cover and is 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 510. Unlike the first state, the first flat portion 401 faces downward.

[0088] In order to distinguish it from the first direction mentioned above, the following can be called the second direction. The second direction can form an angle of nearly 90° with the first direction, but it is not limited to this. It can mean that it is bent in a direction different from the first direction.

[0089] The second state is a state in which the angle between the first planar portion 401 and the second planar portion 402 is further reduced from the first state. While the variable portion 403 bends and deforms with a specified curvature, the display module 400 can move in the first direction to be led out through the panel opening 510.

[0090] The third state is the state in which the display module 400 extends further from the second state, increasing the area facing the second direction. Therefore, the second state in which the display module 400 extends only a portion can be called half-screen, and the state in which the display module 400 extends to the maximum extent can be called full-screen.

[0091] 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.

[0092] The base module 100 can be fixed to a vehicle or the like, and may include a guide wall 110. The guide wall 110 has tracks 120 and 130 formed therein as a drive unit for guiding the movement of the bending module 200 and the sliding module 300. There may be only one guide wall 110, or a pair may be arranged separately in the lateral direction to keep the display module 400 moving in a balanced left-right manner.

[0093] 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.

[0094] Figure 7 This is an exploded perspective view of the base module 100 of a display device 1000 according to an embodiment of the present invention. The tracks 121, 122, 123, and 130 formed on the guide wall 110 may include a plurality of tracks, which may be composed of a first guide wall 111 and a second guide wall 112, so that the plurality of tracks 121, 122, 123, and 130 do not overlap with each other.

[0095] The first surface 111a of the first guide wall 111 and the second surface 112b of the second guide wall 112 can be configured to face each other, and a rotating arm 230 of the bending module 200 can be provided between the first guide wall 111 and the second guide wall 112.

[0096] A curved guide pin 260 protruding laterally toward the rotating arm 230 can be inserted into the curved guide rail 120. Curved guide rails 121, 122, and 123 can be separately formed on the first surface 111a of the first guide wall 111 and the second surface 112b of the second guide wall 112. The curved guide rails 121, 122, and 123 can be composed of horizontal straight portions 121a, 122a, and 123a and inclined portions 121b, 122b, and 122c located at their ends in the first direction and inclined upwards or downwards.

[0097] The rotating arm 230 can rotate as the positions and angles of the inclined portions 121b, 122b, and 122c change, simultaneously with the changes in the positions of the first curved guide pin to the third curved guide pin 261, 262, and 263. For example, the rotating arm 230 can rotate by aligning the inclined portion 121b of the first curved guide rail 121 downwards and the inclined portion 122b of the second curved guide rail 122 upwards.

[0098] In addition to the bending guide rails 121, 122, and 123 that guide the bending module 200, the guide wall 110 may include a sliding rail 130 that guides the sliding motion of the sliding module 300.

[0099] The sliding module 300 may include a first sliding pin 370 that moves along the sliding track 130. The sliding track 130 may be as follows: Figure 7 As shown, the sliding track 130 is formed on the first surface 112a of the second guide wall 112 so that the path of the sliding pin 270 does not overlap with the drive of the rotating arm 230. Alternatively, the sliding track 130 may also be formed on the second surface 111b of the first guide wall 111 where the curved guide track 120 is not formed.

[0100] For switching from the first state to the second state, from the second state to the third state, or vice versa, the display module 400 may include a bending module 200 and a sliding module 300.

[0101] Figure 8 This is a perspective view of the curved module 200 of a display device 1000 according to an embodiment of the present invention, viewed from above. Figure 9 This is a perspective view of the curved module 200 of a display device 1000 according to an embodiment of the present invention, viewed from below.

[0102] 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 connector 220, and a first drive portion 210.

[0103] The back plate 240 can be attached to the back of the first flat portion 401 of the display module 400. The back plate 240 transmits the driving force of the bending module 200 to the first flat portion 401 through a pin-slot connection without hindering the driving of the sliding module 300.

[0104] 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 to switch from the second state to the third state.

[0105] The rear plate 240 may include a rear groove 241 extending along a first direction. The rear plate 240 may be fastened to the rear of the first planar portion 401 of the display module 400 by means of a rear pin 443 through the rear groove 241 and a pin-groove engagement with the first planar portion 401.

[0106] The rotating arm 230 can form a predetermined angle with the rear plate 240 and extend. If the rotation of the rotating arm 230 causes a change in its configuration, the configuration of the rear plate 240 changes, thereby enabling a transition from a first state to a second state.

[0107] The connection 235 between the rotating arm 230 and the rear plate 240 may include a curve corresponding to the curvature of the variable part 403 as a section that supports the bent portion of the variable part 403 in the second state, so that the variable part 403 can form a curve and bend with a predetermined curvature.

[0108] It may include a first planar portion located on the rear plate 240 and a planar support portion located on the back of the flat plate cover 321, and the end of the planar support portion in the third direction opposite to the first direction may also include a curved support portion 245 having a curved surface with a curvature corresponding to the curvature of the rotating arm 230 and the connecting portion.

[0109] The rotating arm 230 may include a plurality of curved guide pins 260. The curved guide pins 260 are protrusions that are inserted into a curved guide rail 120 formed in the guide wall 110 for movement along the curved guide rail 120. Rotatable bearings or rollers may be included on the outer surface to facilitate movement along the curved guide rail 120.

[0110] The first curved guide pin 261, which moves along the first curved guide track 121 formed on the first surface of the first guide wall 111, and the second curved guide pin 262, which moves along the second curved guide track 122 formed on the second surface of the second guide wall 112, can be formed in opposite directions of the rotating arm 230.

[0111] The curved guide pin 260 can move along the curved guide rail 120 and guide the rotational movement of the rotating arm 230. The first curved guide rail 121 and the second curved guide rail 122 can intersect each other (see reference). Figure 12 ( ), to change the configuration of the rotating arm 230.

[0112] Although rotational motion can be guided by only two points of support, including the first curved guide pin 121 and the second curved guide pin 122, a third curved guide rail 123 and a third curved guide pin 263 may be included for more stable support.

[0113] Three curved guide pins 260 can be configured in a triangular shape for stable support. (See reference) Figures 12 to 14 In the first and second states, the rotating arm 230 is able to rotate as the positions of the three curved guide pins 260 change.

[0114] The rotating arm 230 can be rotatably fastened to one end of the bending connector 220 via the rotating shaft 250. The rotating arm 230 can receive the power of the first drive unit 210 via the bending connector 220 and can rotate independently of the bending connector 220 to guide the bending deformation of the variable part 403.

[0115] The first drive unit 210 can be fixed to the base module 100 and can be composed of a first motor 211, a first gear block 212, a first ball screw 213, and a first drive nut 214. It may include a first gear block 212 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, moves along the extension direction of the first ball screw 213, thereby changing its position in the first direction.

[0116] The first drive nut 214 is 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 for driving only in the first direction.

[0117] 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 that guides the sliding module 300.

[0118] The curved connector 220 provides the driving force of the first drive unit 210, which moves in a third direction in a first direction or the opposite direction, to the rotating arm 230. The rotating arm 230 can convert the driving force of the first drive unit 210 provided in a linear direction into rotational motion via the curved guide rail 120 and the curved guide pin 260. Figures 12 to 15 The specific driving mechanism of the rotating arm 230 is explained in the text.

[0119] Figure 10 This is a perspective view of the sliding module 300 of a display device 1000 according to an embodiment of the present invention, viewed from above.

[0120] When transitioning from the second state to the third state, the sliding module 300 pushes the second planar portion 402 of the display module 400 toward the first direction, causing the first planar portion 401 to move further toward the second direction, thereby increasing the area of ​​the exposed display module 400.

[0121] The sliding module 300 may include: a sliding frame 320 fastened to the bending connector 220 of the bending module 200 via a rotation shaft 250; and a second drive unit 310 fixed to the sliding frame 320.

[0122] The second drive unit 310 may include: a second motor 311; a second ball screw 313 that receives power from the second motor 311 to rotate and extends along a first direction; and a second gear block 312 composed of a plurality of gears that transmit the force of the second motor 311 to the second ball screw 313.

[0123] This may include a second drive nut 314 through which the second ball screw 313 passes and moves in a first direction. A bearing ball may be provided between the second drive nut 314 and the second ball screw 313 to reduce the gap between them and decrease friction, thereby making the movement of the second drive nut 314 smooth. The second drive nut 314 may be fastened to the second flat cover 422 located on the display module 400. Figure 11 ) nut fastening part 430.

[0124] Figure 11 This is a perspective view of the sliding module 300 of a display device 1000 according to an embodiment of the present invention, viewed from below.

[0125] The display panel 410 is composed of a first flat part 401, a second flat part 402 and a variable part 403 located between them. The bending module 200 provides power to the first flat part 401 and the sliding module 300 provides power to the second flat part 402.

[0126] 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 curved rods 423 located on the back of the variable portion 403 and supporting it.

[0127] A plurality of rear pins 443 may be located on the back side of the first flat portion 401, and the plurality of said rear pins 443 are inserted into the rear groove 241 of the rear plate 240 of the bending module 200. When transitioning from the second state to the third state, if the sliding module 300 pushes the second flat portion 402 in the second direction, and the first flat portion 401 is pushed and moves in the second direction, the rear pins 443 move in the second direction along the rear groove 241.

[0128] In explanation Figure 20 and Figure 21 When driving the sliding module 300, the driving of the rear pin 443 and the rear groove 241 will be explained in more detail.

[0129] In contrast to the rear pin 443 and the rear slot 241, a sub-rear slot 241 located on the back of the display module 400 and a sub-rear pin 443 protruding from the rear plate 240 may be included.

[0130] The panel gear 447 located on the first flat panel cover 421 can engage with the panel rack 243 located on the rear panel 240 to prevent it from being pushed when the display module 400 is slidably driven.

[0131] Panel gear 447 can be like Figure 11 As shown, there is a pair of them, which can be connected by gear shaft 448 in order to synchronize the pair of panel gears 447.

[0132] The variable section 403 can be supported on the back of the display panel 410 by a plurality of bending rods 423 extending horizontally. The angle between the bending rods 423 changes, causing the curvature of the variable section 403 to change. The bending rods 423 can be connected to adjacent bending rods 423 using a flexible material.

[0133] The back of the bending rod 423 may include a first display pin 441. The first display pin 441 may have a hook shape that protrudes from the back of the bending rod 423 and bends laterally.

[0134] Since the spacing of the first display pins 441 may be too narrow when all the bending rods 423 are formed with the first display pins 441, the bending rods 423 in this embodiment can be alternately configured with bending rods 423 including the first display pins 441 and bending rods 423 without the first display pins 441, thereby providing space for the first display pins 441 to move when the variable part 403 bends.

[0135] The first display pin 441 moves along the first display track 341 formed in the sliding module 300 in the first state (see reference). Figure 24 When transitioning to the second state, it can move towards and along the second display track 242 on the rear panel 240 (see reference). Figure 25 and Figure 26 ).

[0136] When transitioning from the second state to the third state, the first display pin 441 can move along the second display track 242 in the second direction (see reference). Figure 26 Later, in Figures 23 to 26 To explain in more detail the driver of the first display pin 441.

[0137] Figures 12 to 15 This is a side perspective view showing the process of a display device 1000 according to an embodiment of the present invention transitioning from a first state to a third state. Figure 12 The first state is shown. Figure 13 The intermediate process of transitioning from the first state to the second state is shown. Figure 14 The second state is shown. Figure 15 The third state is shown.

[0138] In the first state where the first planar portion 401 and the second planar portion 402 form the same plane and the variable portion 403 is not bent, the description is based on the position of the first drive portion 210 and the position of the second drive portion 310.

[0139] If the first motor 211 of the first drive unit 210 is driven, the first ball screw 213 rotates, and the first drive nut 214 pushes the drive frame 225 in the first direction. The bent connector 220 also moves in the first direction together with the drive frame 225, and the rotating arm 230, which is connected to the bent connector 220 by the rotating shaft 250, can also move under the force in the first direction.

[0140] The driving force received by the rotating arm 230 in the first direction can be converted into a force that moves the plurality of guide pins along the guide rail and rotates the rotating arm 230. At this time, the rotating arm 230 can be connected to the bending connector 220 through the rotating shaft 250, so the rotating arm 230 can rotate independently of the bending connector 220.

[0141] The rotating arm 230 may include: a first arm 231 connected to the rear plate 240; a second arm 232 extending forward from the first arm 231; and a third arm 233 bent upward from the second arm 232. The first arm 231 may... Figure 12 In the first state shown, it extends in a direction away from the display module 400. Figure 14 and Figure 15 The second and third states shown show the back of the support display module 400.

[0142] Therefore, the angle between the rear plate 240 and the first arm 231 of the rotating arm 230 can be an angle corresponding to the configuration angle of the first planar portion 401 and the second planar portion 402 in the second and third states.

[0143] In particular, such as Figure 14 As shown, the rotating arm 230 supports the variable portion 403 (facing the top surface) in the second state, which is not yet bent and forms the same plane as the second planar portion 402. The end of the first arm 231 connected to the rear plate 240 has a curvature corresponding to the bending curvature of the variable portion 403, so that one end of the first arm 231 can support the bent portion of the variable portion 403 in both the second and third states.

[0144] Reference Figure 12 The second arm 232 can be bent and extended in a first direction from the other end of the first arm 231, and the third arm 233 can be bent upward from the end of the second arm 232. The third arm 233 serves as a part for configuring the second curved guide pin 262 and the third curved guide pin 263, and the second arm 232 connects the third arm 233 to the first arm 231.

[0145] The rotating arm 230 can also be configured to extend from the first arm 231 to the position where the second curved guide pin 262 and the third curved guide pin 263 are formed, without requiring the first arm 231, the second arm 232, and the third arm 233 to form a U-shaped bend. However, this would increase the size and weight of the rotating arm 230.

[0146] In addition, such as Figure 14 and Figure 15 As shown, since the fixing groove 234 for the fixing pin 124 supporting the rotating arm 230 is too long when the bending module 200 is in the off state, the rotating arm 230 can be formed into a U-shaped form.

[0147] The rotating arm 230 may include a first curved guide pin 261 and a second curved guide pin 262 that project laterally from different positions. For example... Figure 9 As shown, the first curved guide pin 261 and the second curved guide pin 262 are oriented in different directions from each other.

[0148] The first curved guide pin 261 can move along the first curved guide track 121 formed on the first surface of the first guide wall 111 along the path P1. The second curved guide pin 262 can move along the second guide track formed on the second surface of the second guide wall 112 along the path P2.

[0149] exist Figure 12 In the first state, the first curved guide pin 261 is located closer to the upper side than the second curved guide pin 262, but... Figure 14 In the second state, the rotating arm 230 rotates so that the second curved guide pin 262 is located closer to the upper side than the first curved guide pin 261.

[0150] The first curved guide pin 261 is located in the straight portion 121a of the first curved guide rail 121 in the first state. When the first drive unit 210 is driven, it moves along the first curved guide rail 121 in the first direction and reaches the inclined portion 121b, and the inclined portion 122b of the first curved guide rail 121 tilts downward.

[0151] The inclined portion 121b of the first curved guide rail 121 and the inclined portion 122b of the second curved guide rail 122 can be as follows: Figure 12 They intersect each other as shown in the side perspective view. However, since the first curved guide rail 121 and the second curved guide rail 122 are formed on different guide walls 110, the first curved guide pin 261 and the second curved guide pin 262 can move without interfering with each other.

[0152] When the first curved guide pin 261 moves downward along the inclined portion 121a of the first curved guide track 121, the second curved guide pin 262 remains located in the straight portion 122a of the second curved guide track 122, causing the rotating arm 230 to begin rotating.

[0153] like Figure 13 As shown, if the first curved guide pin 261 reaches the lower end 121c of the inclined portion 121a of the first curved guide rail 121, the first curved guide pin 261 temporarily stops moving, and the second curved guide pin 262 moves along the inclined portion 121d on the upper side of the second curved guide rail 122, so that the rotating arm 230 can rotate in sequence.

[0154] The inclined portion of the first curved guide rail 121 may have a V-shape that bends upward from the lower end. If the first curved guide pin 261 and the second curved guide pin 262 reach the first direction end of the first curved guide rail 121 and the second curved guide rail 122, the rotating arm 230 stops rotating.

[0155] When the rotation of the rotating arm 230 is controlled by two guide pins, problems such as difficulty in smooth bending, wobbling, or misalignment may occur. A third curved guide pin 263 and a third curved guide rail 123 may also be included to more stably support and realize the rotational movement of the rotating arm 230.

[0156] When the third curved guide pin 263 is configured to form a triangle with the first curved guide pin 261 and the second curved guide pin 262, it can be driven more stably. Therefore, in order to be separately provided from the third arm 233 on which the first curved guide pin 261 and the second curved guide pin 262 are formed, the third curved guide pin 263 can be located in the first arm 231.

[0157] The third curved guide rail 123, which allows the third curved guide pin 263 to move, can be formed on the first guide wall 111 or the second guide wall 112. In this embodiment, the height of the straight portion of the third curved guide rail 123 is the same as the height of the straight portion of the first curved guide rail 121, so it can be formed on the second guide wall 112 where the second curved guide rail 122 is formed.

[0158] However, the first arm 231 in the second state is as follows Figure 14 As shown, it detaches from the guide wall 110 and transforms into a state supporting the back of the display module 400. Since the third curved guide pin 263 is located on the first arm 231, it moves along... Figure 12 The P3 trajectory moves, such as Figure 14 As shown, it is located on the back of the display module 400 in the second state.

[0159] In the second state, the third bending guide pin 263 is at the same horizontal height as the bending connector 220. Therefore, in order to avoid interference with the bending connector 220, the bending connector 220 can form a pin groove 221 at the position corresponding to the third bending guide pin 263 in the second state.

[0160] The trajectory P3 of the third curved guide pin 263 can be as follows: Figure 13 As shown, it overlaps with the display module 400, so it is impossible to extend the length of the third curved guide rail 123 to the end by increasing the size of the guide wall 110.

[0161] Therefore, as Figure 13 As shown, if the variable part 403 bends to a constant angle, the third bending guide pin 263 of the present invention disengages from the third bending guide track 123, as shown in the figure. Figure 14 The second state shown is located on the back of the display module 400. If the third curved guide pin 263 disengages from the third curved guide rail 123 in the second state, the aforementioned stable three-point support cannot be achieved.

[0162] A retaining pin 124, inserted into the retaining groove 234 to support the rotating arm 230 in the second state, may be formed in the guide wall 110. (See reference...) Figure 7 It can be formed in the second guide wall 112, and the fixing groove 234 can be as follows: Figure 9 It is formed in the second arm 232 as shown.

[0163] In the second state, the retaining pin 124 can be placed at the end of the retaining groove 234 to stably fix the position of the rotating arm 230. When the rotating arm 230 does not have a U-shape and the first arm 231 is connected to the third arm 233, the length of the retaining groove 234 may become longer.

[0164] Figure 16 This is a perspective view showing the shaft groove 350 and the rotation shaft 250 in a first state of a display device 1000 according to an embodiment of the present invention.

[0165] Figure 17 This is a side view showing the shaft groove 350 and the rotation shaft 250 in a first state of a display device 1000 according to an embodiment of the present invention. Figure 18 This is a side view showing the shaft groove 350 and the rotation shaft 250 in a second state of a display device 1000 according to an embodiment of the present invention.

[0166] The shaft groove 350 is an arched groove formed in the sliding frame 320, and the center 355 of the shaft groove 250 can be located on the outside of the sliding frame 320.

[0167] The rotating shaft 250 of the present invention may not be fixed in a specific position, but may move and rotate in an arched shape. In order to guide the rotating shaft 250 to move along an arched trajectory, the rotating shaft 250 may be inserted into an arched shaft groove 350 and move and rotate along the shape of the shaft groove 350.

[0168] When transitioning from the first state to the second state, the rotating shaft 250 can move from the third directional end opposite to the first directional end of the shaft groove 350 back to the first directional end of the shaft groove 350. During the transition from the first state to the second state, the position of the rotating shaft 250, which serves as the fastening position between the sliding frame 320 and the bent connector 220, changes.

[0169] Reference Figure 14 When the first drive unit 210 drives the transition from the first state to the second state, the moving distance of the sliding frame 320 in the first direction can be less than the moving distance of the drive frame 225 in the first direction. Figure 14 (b < a). The difference between the moving distance a of the drive frame 225 and the moving distance b of the sliding frame 320, a - b, can correspond to the extension length of the shaft groove 350.

[0170] The first planar portion 401 of the display module 400 is connected to the bending module 200, and the second planar portion 402 is connected to the sliding module 300. Therefore, the sliding module 300 moves rearward (in a third direction) relative to the bending module 200 by a length equivalent to the shaft groove 350. Correspondingly, the second planar portion 402 needs to be moved in a first direction relative to the sliding module 300. The second drive portion 310 of the sliding module 300 can move the second planar portion 402 in the first direction relative to the sliding frame 320.

[0171] Furthermore, since the radius of curvature of the variable part 403 is greater than that of the curved support part 245, the second planar part 402 of the display module 400 is further pulled towards the first direction under the action of the radius of curvature. In order to compensate for the deviation in sliding distance caused by the radius of curvature when the display module 400 is bent and deformed, the first drive part 210 slides the second planar part 402 towards the second direction by more than the length of the sliding groove 350.

[0172] Therefore, the moving distance c of the second planar portion 402 of the second drive unit 310 can be greater than the difference between the moving distance a of the drive frame 225 and the moving distance b of the sliding frame 320, that is, c > a - b.

[0173] The rotating shaft 250 moves along the arched shaft groove 350, and the center of the rotation trajectory of the rear plate 240 and the rotating arm 230 can be the same as the center 355 of the shaft groove 350.

[0174] like Figure 18As shown, the rotation center 355 of the rear plate 240 and the rotating arm 230 corresponds to the curvature center 355 of the curved surface of the variable part 403, and coincides with the center 355 of the arched shape of the shaft groove 350. The curvature center 355 of the curved surface of the variable part 403 can be located on the outside of the rotating arm 230 and the rear plate 240.

[0175] Figure 19 The diagram shows the case where the rotating arm 230 moves and rotates in a first direction by receiving the driving force of the first drive unit 210 of the bending module 200, while the rotating shaft 250 is fixed.

[0176] and Figure 17 and Figure 18 In a different embodiment, the rear plate 240 and the rotating arm 230 rotate around a fixed rotation axis 250, and the curvature center of the surface of the variable part 403 is the rotation axis 250.

[0177] Therefore, as Figure 16 As shown, the thickness of the rear plate 240 and the bending module 200 that fixes it increases. In the second and third states, the rear plate 240 is located on the outside through the panel opening 510 of the cover 500. Therefore, if the thickness of the rear plate 240 is greater, the size of the panel opening 510 needs to be increased. If the size of the panel opening 510 is increased, there is a problem that internal components can be seen through the panel opening 510 even in the first state.

[0178] The rotation trajectory of the rotating shaft 250 of the present invention when moving along the arched shaft groove 350 is about a virtual center 355 located outside the rear plate 240 or the rotating arm 230. Therefore, the display device 1000 of the present invention can achieve a higher performance than... Figure 19 The embodiment features a thinner rotating arm 230 and rear plate 240, which also allows for a reduction in the size of the panel opening 510.

[0179] After the bending module 200 completes the drive and transitions to the second state, as follows: Figure 5 As shown, the first planar portion 401 moves further in the second direction, thereby transforming into a third state in which the area facing forward of the display module 400 is further increased.

[0180] Figure 20 This is a perspective view of the sliding module 300 and the display module 400 in a second state of a display device 1000 according to an embodiment of the present invention, viewed from below. Figure 21 This is a perspective view of the sliding module 300 and the display module 400 in the third state of a display device 1000 according to an embodiment of the present invention, viewed from below.

[0181] like Figure 14As shown, the first drive unit 210 is also mainly responsible for driving when transitioning to the second state, so the display module 400 is in a state where it moves a constant distance c1 relative to the sliding frame 320.

[0182] When transitioning from the second state to the third state, the first drive unit 210 of the bending module 200 stops driving, and only the second drive unit 310 of the sliding module 300 is driven, thereby allowing the display module 400 to move. At this time, the display module 400 can slide relative to the bending module 200.

[0183] The rear plate 240 may include a plurality of rear grooves 241 to allow the display module 400 to slide and move in a state where the rear plate 240 of the first flat portion 401 and the bending module 200 are fixed. The plurality of rear grooves 241 extend in a first direction (in a second state in a second direction) so that a structure protruding from the back of the first region of the display module 400 can move in the first direction.

[0184] A display pin protruding from the back of the first flat portion 401 can be inserted into the rear slot 241, and the display pin can move along the length of the rear slot 241. In the second state, located as... Figure 20 The end shown is the upper side in the attached diagram, but if it is converted to the third state, it can be as follows: Figure 21 Move towards the other end (the lower side in the attached diagram) as shown.

[0185] The rear pin 443 can be located at one end of the rear groove 241 in the first state, just as it is in the second state, and can be switched from the state of being located at one end of the rear groove 241 to the second state. The force that causes the bending module 200 to move and rotate in the first direction can be transmitted to the first planar portion 401 of the display module 400 through the rear groove 241 and the rear pin 443.

[0186] When transitioning from the second state to the third state, the distance that the rear pin 443 moves in the rear slot 241 can correspond to the driving distance of the second drive unit 310.

[0187] Figure 22 This is a diagram showing the rear slot 241 and rear pin 443 of a display device 1000 according to an embodiment of the present invention. Figure 20 A three-dimensional view of the CC section. (Refer to...) Figure 22 The width of the rear groove 241 that connects with the display module 400 is relatively narrow, and the width of the roller or bearing in the rear pin 443 is increased, so as to prevent the rear pin 443 from detaching from the rear groove 241.

[0188] After the rear plate 240 is placed on the back of the first flat portion 401, the rear pin 443 can pass through the rear groove 241 and be fixed to the back of the first flat portion 401. Two or more rear pins 443 and rear grooves 241 can be included to enable the display module 400 to achieve more stable sliding movement.

[0189] Reference Figure 8 The rear plate 240 may further include an auxiliary rear pin 244 protruding toward the first plane of the display module 400. The auxiliary rear pin 244 is inserted into an auxiliary rear groove 444 formed in the first planar portion 401 (see reference). Figure 11 It can move along the length of the auxiliary rear groove 444.

[0190] The auxiliary rear slot 444 and the auxiliary rear pin 244 are not fastening structures between the rear plate 240 and the display module 400, but only serve to assist the sliding movement in the second direction when transitioning from the second state to the third state.

[0191] Figures 23 to 26 This is a cross-sectional view illustrating the process by which a display device 1000 according to an embodiment of the present invention transitions from a first state to a third state. Figure 27 It is shown Figure 24 A three-dimensional cross-sectional view of the first display pin 441, the first display track 341, and the second display track 242 in their respective states.

[0192] The first display pin 441 may have a hook shape that protrudes from the back of the bending rod 423 and bends laterally. The outer peripheral surface of the first display pin 441 may include rollers and bearings to allow the first display pin 441 to slide more smoothly.

[0193] The first display track 341 and the second display track 242 are also open to the side, and the first display pin 441 can move while in contact with at least one of the top surface (the surface adjacent to the display module 400) and the bottom surface (the surface away from the display module 400) of the first display track 341 and the second display track 242.

[0194] It may include a plurality of first display pins 441 protruding from the back of the variable portion 403. The first flat portion 401 is constructed entirely of a single solid material, so even if one of the coupled rear pins 443 is provided on each of the left and right sides, the sliding movement of the first flat portion 401 can be adequately guided.

[0195] However, the variable part 403 is composed of a plurality of adjacent bent rods 423 in the first direction, so the number of first display pins 441 is greater than the number of rear pins 443, so that the bent rods 423 can slide without separating from the support structure on the back. This embodiment shows an example in which a rear pin 443 is provided on each side of every two bent rods 423.

[0196] When rear pins are provided on directly adjacent bending rods 423, they may collide with each other in the bending section. If they are too far apart, it may be difficult to guide the sliding movement while achieving the bending shape of the variable part 403.

[0197] like Figure 23 As shown, in the first state, the first display pin 441 can be located on the first display track 341 formed in the sliding frame 320. The first display track 341 forms a straight line, guiding only the linear movement of the first display pin 441 in the first direction.

[0198] When transitioning from the first state to the second state, the first display pin 441 can be as follows: Figure 24 As shown, the curvature of the variable part 403 changes while it detaches from the first direction end of the first display track 341 and moves toward the second display track 242 of the rear plate 240.

[0199] The second display track 242 is formed on the rear plate 240. When the display module 400 transitions from the second state to the third state, the first display pin 441 can move along the second display track 242 in the second direction (see reference). Figure 26 ).

[0200] The rear plate 240 may include a curved support portion 245 at a third-direction end having a curved surface with a curvature corresponding to the shape of the connecting portion 235 of the rotating arm 230. The second display track 242 extends to the curved support portion 245, and the portion of the second display track 242 located on the back side of the variable portion 403 may have a curve corresponding to the shape of the curved support portion 245.

[0201] However, as Figure 24 and Figure 27 As shown, while forming the bend, the top surface of the second display track 242, that is, the surface facing the back of the display module 400, is open, so that the first display pin 441 can move from the first display track 341 to the second display track 242.

[0202] If the second display track 242 does not extend to the curved support portion 245, the first display pin 441 may have difficulty moving from the first display track 341 to the second display track 242. Therefore, the formation of the second display track 242 on a portion 242b of the curved support portion 245 serves to guide the first display pin 441 so that it can move stably to the second display track 242.

[0203] In the second state, the area of ​​the variable part 403 facing the top surface is larger than the area facing the front (first direction), so a portion of the first display pin 441 is located on the first display track 341.

[0204] If the second drive unit 310 pushes the second flat portion 402 in the first direction, the first display pin 441 moves toward the second display track 242, and the area of ​​the variable portion 403 facing the front widens. The first flat portion 401 is pushed in the second direction by the variable portion 403, such as... Figure 26 As shown, it can be converted into the third state, which is the largest in area facing the front of the display module 400.

[0205] The second planar portion 402 can be fastened to the second drive nut 314 of the second drive portion 310 and moved in the first direction. It may also include a second display pin 442 protruding from the back of the second planar portion 402 so that the second planar portion 402 can move stably in the first direction without twisting.

[0206] The second display pin 442 can move along the third display track 343 formed in the sliding frame 320. For example... Figure 11 As shown, since the second display pins 442 are located within the solid first flat cover 421, their number can be less than that of the first display pins 441. This embodiment includes two on each side, for a total of four second display pins 442.

[0207] Reference Figure 10 The third display track 343, which opens to the side, is formed on both sides facing each other. When the first display pin 441 and the second display pin 442 are arranged in a continuous position in the first direction, the first display track 341 can be connected to the third display track 343.

[0208] However, as Figure 11 As shown, the first display pin 441 and the second display pin 442 can be located on different planes from each other. In this case, refer to Figure 10 In order to make the second display track 242 and the first display track 341 also located on different planes from each other, the side of the sliding frame 320 can be divided into a first side 321 and a second side 322.

[0209] The third display track 343 and the first display track 341 can be configured separately in the lateral direction of the display device 1000 so that the second display pin 442 can pass through.

[0210] As described above, the display device 1000 of the present invention can bring out the display module when needed and store it when not in use.

[0211] Furthermore, the display device 1000 of the present invention can be arranged horizontally when stored and vertically when extended, so it can be arranged even if there is insufficient storage space in the vertical direction.

[0212] Furthermore, by making the structure of the curved module 200 supporting the back of the display module 400 thinner, the display device 10 of the present invention can reduce the size of the panel opening 510 formed in the cover 500.

[0213] Furthermore, the display device 1000 of the present invention can achieve stable bending drive through a three-point support rotating arm 230.

[0214] Furthermore, the display device 1000 of the present invention provides a sliding guide structure for the display module 400 in the rear direction of the display module 400, thereby reducing the bezel size in the left and right directions of the display module 400.

[0215] The detailed description above should not be construed as restrictive in all respects, but rather as illustrative. 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.
