Description

[0001] Cross-reference to related applications

[0002] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2023-0118372 filed on September 6, 2023, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference. Technical Field

[0003] The present disclosure relates to a flexible display device for a vehicle (applicable to vehicles in all fields), a method for controlling the display device, and a vehicle equipped with the display device, and more particularly, to an apparatus and method for supporting a device capable of retracting or extending (retracting / extending) a flexible display that can be bent or twisted. Background Art

[0004] The center panel display of the vehicle can display various visual information related to the vehicle. Such a display device can also be installed on the dashboard of the vehicle arranged in front of the driver's seat and the front passenger seat, and provide various convenient information such as navigation, vehicle management and operation, Internet, and entertainment.

[0005] In this regard, there is a movable display device, and the movable display device can be moved up and down or left and right relative to the instrument panel. When the display moves along the guide, the driver and the passenger can selectively use the display. In the case where the display is in a pop-up form, the display can be stored and then extended and used when necessary.

[0006] Since the installation position of a fixed display is fixed, the space usage in the vehicle is limited, and as the display size increases, the forward visibility decreases. A pop-up movable display requires a separate accommodation space for the display, and as the size of the display increases, the size of the accommodation space also increases, thereby limiting the space usage in the vehicle. In addition, since the LCD display is a full-screen operation, all power is used regardless of the exposure of the display, so there is a problem of inefficiency.

[0007] Therefore, there is a need to develop a display device in a form and structure that has the advantages of multiplying these disadvantages while minimizing these disadvantages. Summary of the invention

[0046] The accompanying drawings are provided only to help understand the embodiments of the present disclosure and do not constitute limitations to the technical features set forth herein. It should be understood that the present disclosure includes all modifications, equivalents or substitutions within the scope and spirit of the present disclosure.

[0047] Ordinal numbers (such as 1st, 2nd, first, and second) may be used to describe a plurality of elements, but the elements are not limited by these terms. The above terms are used only for the purpose of distinguishing one component from another.

[0048] When it is mentioned that a component is “connected” or “coupled” to another component, it may mean that the component is directly connected or coupled to the other component, but a third component may exist in between. On the other hand, when it is mentioned that a component is “directly connected” or “directly coupled” to another component, it may mean that there is no other component between the two components.

[0049] Unless the context otherwise requires, a singular expression includes a plural reference.

[0050] As used herein, the terms “including” or “having” are intended to indicate the presence of a feature, number, step, operation, component, part, or a combination thereof, without excluding the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or a combination thereof.

[0051] Figure 1 A conventional display device is shown.

[0052] like Figure 1As shown, the rollable / slidable display devices currently developed by various competitors have less rigidity than fixed display devices due to their design or mounting structure.

[0053] Specifically, when a force such as a pushing load or a pulling load is applied to the display that has been fully extended, the display is easily damaged because the supporting structure of the display is located only at the bottom of the display and is thus weak.

[0054] In this regard, embodiments are directed to providing a display device that supports a display and provides additional rigidity to the display.

[0055] Figure 2 A retracted display in a display device according to an embodiment is shown. Figure 3 A display device according to an embodiment is shown with a display extended.

[0056] like Figure 2 and Figure 3 As shown in FIG. 1 , the display device 100 according to the embodiment may include a display unit 1000 driving and rolling / unrolling the display 1100 and a display supporting unit 2000 supporting the display 1100. The display supporting unit 2000 is preferably located at the rear end of the display unit 1000.

[0057] That is, the display device 100 according to the embodiment has the effect that the display support unit 2000 can support the extended portion of the display 1100 without interfering with the display, so that the display 1100 is not easily damaged by an external force.

[0058] Figure 4 A display unit in a display device according to an embodiment is shown.

[0059] Figure 4 The display units in Figure 2 and Figure 3 The display unit shown in FIG.

[0060] like Figure 4 As shown, the display unit 1000 may include a display 1100, a display driver 1200, and a display winder 1300. Fig.15 A detailed description is given of the display driver 1200 and the display winder 1300 .

[0061] The display 1100 may be a flexible or rollable display 1100. The display 1100 may be a plastic organic light emitting diode (POLED) display. The POLED is an organic light emitting diode (OLED) having a polyimide (PI) substrate which is a kind of plastic, and the POLED may realize a curved surface.

[0062] The display 1100 may be bendable, and the radius of curvature of the display 1100 may be at least 10 mm or greater. The display 1100 may include a light emitting diode (LED) (OLED, active matrix OLED (AMOLED) or passive matrix OLED (PMOLED)). The width and height of the display 1100 may be appropriately designed by those skilled in the art.

[0063] Figure 5 is an exploded view showing a display supporting unit in a display device according to an embodiment.

[0064] Figure 5 The display support unit in corresponds to Figure 2 and Figure 3 The display support unit shown in FIG.

[0065] refer to Figure 5 , the display support unit 2000 may include a housing 2100 , a support member 2200 , and a support member fixer 2300 .

[0066] The housing 2100 may have a support 2200 at a top end thereof and a support holder 2300 therein, and may include an opening to allow the display 1100 to extend or retract therethrough.

[0067] In addition, the housing 2100 may be the instrument panel (IP) of the vehicle itself. In other words, the IP itself may be formed as the housing 2100, wherein the support member holder 2300 is provided in the instrument panel, and an opening is formed so that the display 1100 can be extended or retracted, instead of adding the housing 2100. Therefore, since no additional configuration is added, there is an effect that various designs can be used.

[0068] The support member 2200 is disposed at the top end of the housing 2100. Specifically, in order to support the display 1100 that can be retracted into the housing 2100 or extended from the housing, the top end portion of the support member 2200 is connected to the rear top end portion of the display 1100, and the bottom end portion of the support member 2200 is connected to the support member holder 2300. Therefore, when the top end portion of the support member 2200 is connected to the rear top end portion of the display 1100 and the bottom end portion of the support member is fixed to the support member holder 2300, the support member 2200 can support the display 1100 even when the display 1100 is fully extended. This will refer to Figure 6 and Figure 7 Detailed description.

[0069] In addition, the support member 2200 can be linearly moved in the front-to-rear direction according to the movement of the display 1100. For example, when the display 1100 is retracted, that is, when the display 1100 is not in use and is thus lowered, the bottom end portion of the support member 2200 is linearly moved in the rearward (inward) direction of the housing 2100, and thus, the support member 2200 is positioned coplanar with the top end portion of the housing 2100 (see FIG. Figure 2 ). When the display 1100 is extended, that is, when the display 1100 is raised for use, the bottom end portion of the support member 2200 moves linearly in the forward (outward) direction of the housing 2100. Therefore, the support member 2200 is positioned relative to the top end portion of the housing 2100 (see Figure 3 )tilt.

[0070] The support member fixer 2300 may fix the bottom end portion of the support member 2200 so that the support member 2200 may move linearly. That is, the support member fixer 2300 may be located inside the housing 2100 and fix the position of the bottom end portion of the support member 2200 according to the retraction / extension of the display 1100. Figure 8 and Fig. 9 A detailed description is given of the support member holder 2300.

[0071] Figure 6 A top end portion of a support member in a display device according to an embodiment is shown. Figure 7 A bottom end portion of a support member in a display device according to an embodiment is shown.

[0072] Figure 6 The supports in Figure 5 The support member shown in FIG. Figure 6 The support fixture in corresponds to Figure 5 The support member fixture shown in FIG. Figure 7 The supports in Figure 5 The support member shown in FIG. Figure 7 The support fixture in corresponds to Figure 5 The support member fixture shown in FIG.

[0073] First, refer to Figure 6 , the connection between the top end portion of the support 2200 and the rear top end portion of the display 1100 will be described.

[0074] A first protrusion 2210 is formed on both side surfaces of the top end portion of the support 2200, and a first coupling portion 2211 that can be coupled to the first protrusion 2210 is formed on the rear top end portion of the display 1100. More specifically, the first protrusion 2210 and the first coupling portion 2211 can be hinged. Each first coupling portion 2211 can include a 1a portion and a 2a portion, the 1a portion being fixedly coupled to the rear top end portion of the display 1100, and the 2a portion having a first through hole formed therein, which can be hinged to the first protrusion 2210.

[0075] That is, the first protrusion 2210 formed on the side surface of the support 2200 and the first coupling portion 2211 formed on the rear top end portion of the display 1100 are hinged to each other so that the first protrusion 2210 can rotate while being coupled to the first through hole formed in the first coupling portion 2211. Figure 6 As shown in FIG. 1 , when the display 1100 is fully extended, the support member 2200 is inclined relative to the top surface of the housing 2100 (see also FIG. 1 ). Figure 3 ), and then when the display is lowered to retract, the top portion of the support member 2200 can also move with the movement of the display 1100.

[0076] refer to Figure 7 , the connection between the bottom end portion of the support member 2200 and the support member fixer 2300 will be described.

[0077] First, the support member holder 2300 may include a movable plate 2310 that can slide (or linearly move) in the inner and outer directions of the housing 2100 together with the support member 2200. In other words, when the bottom end portion of the support member 2200 is connected to the movable plate 2310, the movable plate 2310 can move together with the support member 2200.

[0078] More specifically, similar to the first protrusion 2210, the second protrusion 2220 is formed on both side surfaces of the bottom end portion of the support 2200, and a second coupling portion 2221 that can be coupled to the second protrusion 2220 is provided on the top end portion of the movable plate 2310. The second protrusion 2220 can be hinged to the second coupling portion 2221. Each second coupling portion 2221 can include a 1b portion fixedly coupled to the top end portion of the movable plate 2310 and a 2b portion having a second through hole formed therein to which the second protrusion 2220 can be hinged.

[0079] That is, when the second protrusion 2220 formed on the side surface of the support 2200 is hinged to the second coupling portion 2221 formed on the top end portion of the movable plate 2310, the second protrusion 2220 can rotate while the second protrusion is coupled to the second through hole formed in the second coupling portion 2221. Figure 7 As shown, when the display 1100 is fully retracted (wherein the support member 2200 is coplanar with the top surface of the housing 2100) (see also Figure 2 ) is raised to extend, the bottom end portion of the support member 2200 can also move with the movement of the display 1100.

[0080] Since the top end portion of the support member 2200 is hinged to the display 1100 and the bottom end portion is hinged to the movable plate 2310, the support member 2200 can move linearly at a varying angle according to the upward and downward movement of the display 1100. For example, when the display 1100 is raised to extend, the support member 2200 also moves in the outward (forward) direction of the housing 2100, and the movable plate 2310 also naturally moves in the outward (forward) direction of the housing 2100. When the display 1100 is lowered to retract, the support member 2200 moves in the inward (backward) direction of the housing 2100, and the movable plate 2310 also naturally moves in the inward (backward) direction of the housing 2100. As described later with reference to Fig.19 Described in detail, when the display driver 1200 moves the display 1100, the support 2200 hinged to the display 1100 also eventually moves.

[0081] Figure 8 A support member holder in a display device according to an embodiment is shown. Fig. 9 A support fixture in a display device according to an embodiment is shown, wherein a locking plate is removed from the support fixture.

[0082] Figure 8 The support fixture in corresponds to Figure 5 The support fixture in the. Fig. 9 The support fixture in corresponds to Figure 5 The support fixture in the.

[0083] refer to Figure 8 and Fig. 9 , the support member holder 2300 includes a movable plate 2310, a first bracket 2320, a second motor 2321, a locking plate 2330, a plate 2340, a cam 2350, and a sensor 2370. The movable plate 2310, the locking plate 2330, and the plate 2340 are rectangular plates, the locking plate 2330 is formed on the plate 2340, and the movable plate 2310 is formed on the locking plate 2330.

[0084] A roller 2315 that makes line contact with the first bracket 2320 may be formed on the side surface of the movable plate 2310. Figure 7 As described, the movable plate 2310 may slide (linearly move), and the rollers 2315 formed on the side surface of the movable plate 2310 rotate to enable the movable plate 2310 to slide (linearly move).

[0085] The first bracket 2320 may be formed on the side surfaces of the movable plate 2310, the locking plate 2330, and the plate 2340, and the second motor 2321, the pulley 2322, and the sensor 2370 may be disposed on the first bracket 2320. In addition, a first stopper 2325 that may prevent the roller 2315 from moving may be formed at one end of the first bracket 2320. The first stopper 2325 may prevent the rotational movement of the roller 2315, thereby preventing the movable plate 2310 from moving beyond the operating range of the movable plate 2310.

[0086] The second motor 2321 may transmit a driving force to the cam 2350 so that the locking plate 2330 may move. The second motor 2321 may be a stepping motor or a pulse motor.

[0087] The shaft 2351 and the cam 2350 may be disposed between the locking plate 2330 and the plate 2340. Fig. 9 , shows a support member holder 2300, wherein the locking plate 2330 is removed therefrom, a shaft 2351 having one end and the other end fixed to the first bracket 2320, and the shaft is located above the plate 2340, and a cam 2350 is fixed to the shaft 2351. That is, the shaft 2351 is rotated by receiving a driving force transmitted from the second motor 2321, so that the cam 2350 fixed to the shaft 2351 rotates together with the shaft 2351. This will refer to Fig.10 Detailed description.

[0088] The support member holder 2300 may include a sensor 2370. The sensor 2370 may be a photointerrupter (PI) sensor. Depending on the rotation state of the cam 2350, the sensor 2370 may or may not pass through the hole 2361 formed on the sensing portion 2360 that rotates with the cam 2350, which will be referred to as Fig.13 Describe in detail.

[0089] Fig.10 The upward and downward movement of a locking plate in a support fixture of a display device according to an embodiment is shown. Fig.11 The locking plate and the cam in the support fixture of the display device according to the embodiment are shown. More specifically, Fig.11 (a) shows a locking plate, and Fig.11 (b) shows a cam.

[0090] Fig.10 The support fixture in corresponds to Figure 8 and Fig. 9 The support fixture in the. Fig.11 The locking plate in corresponds to Figure 8 and Fig.10 Locking plate in. Fig.11 The cam in corresponds to Fig. 9 and Fig.10 The cam in the

[0091] In order to describe the upward and downward movement of the locking plate 2330, the principle of transmitting the driving force to the cam 2350 through the second motor 2321 will be described.

[0092] As reference Figure 8 and Fig. 9 As described, the second motor 2321 may transmit the driving force to the cam 2350 so that the locking plate 2330 may move. Herein, the second motor 2321 and the cam 2350 may be connected to each other using a plurality of gear parts.

[0093] like Fig.10 As shown, two shafts 2351 may be provided: a first shaft 2351a and a second shaft 2351b. A pulley 2322 may be formed at one end of the first shaft 2351a. Since the pulley 2322 is connected to the second motor 2321 through the second synchronous belt 2323, the driving force of the second motor 2321 may be transmitted to the first shaft 2351a. A sensing portion 2360 may be formed at one end of the second shaft 2351b, which will be referred to as Fig.13 Describe in detail.

[0094] A pulley may also be formed at each of the other end of the first shaft 2351a and the other end of the second shaft 2351b. Similarly, the pulleys formed at the other end of the first shaft 2351a and the other end of the second shaft 2351b may be connected by a second timing belt, thereby enabling the driving force of the second motor 2321 to be transmitted to the second shaft 2351b as well as the first shaft 2351a. Fig.10 The description is described in the context of two axes 2351 in , but the description may also be applicable when more than two axes 2351 are used.

[0095] Therefore, regardless of the number of shafts 2351, the driving force of the second motor 2321 can be transmitted to the shaft 2351 and finally to the cam 2350 fixedly connected to the shaft 2351. The cam 2350 can be rotated by the received driving force, and the rotation axis of the cam 2350 can be the same as the rotation axis of the shaft 2351. In addition, the cam 2350 makes surface contact with a portion of the locking plate 2330, which enables the locking plate 2330 to move up and down by the rotation of the cam 2350.

[0096] Reference together Fig.11 (b), the cam 2350 may include a first surface 2350a formed in a straight line form and a second surface 2350b formed in a curved line form with a gradually decreasing curvature. In other words, the cam 2350 is not disc-shaped, but has a bottom surface with one side of the bottom surface being straight and the other side of the bottom surface being curved. The shaft 2351 may be positioned to pass through the point where the first surface 2350a and the second surface 2350b intersect.

[0097] Since the second surface 2350b is formed in a curve form with a gradually decreasing curvature, different radii are formed from the rotation center (through which the shaft 2351 of the cam 2350 passes) to the second surface 2350b. The reason why the second surface 2350b of the cam 2350 is not in a constant curve form but in a curve form with a gradually decreasing curvature is that the rotation of the cam 2350 enables the locking plate 2330 to move upward and downward.

[0098] That is, for example, when the bottom surface of the cam 2350 is formed in a circle having a constant radius, the locking plate 2330 cannot move due to the constant radius even when the cam 2350 rotates. However, since the cam 2350 of the display device 100 according to the embodiment includes the first surface 2350a formed in a straight line form and the second surface 2350b formed in a curved line form with a gradually decreasing curvature, when the cam 2350 rotates, its radius can become smaller or larger according to the rotation direction of the cam 2350.

[0099] Therefore, when the cam 2350 rotates in a direction in which the radius decreases, the locking plate 2330 may move in an upward direction, and when the cam 2350 rotates in a direction in which the radius increases, the locking plate 2330 may move in a downward direction. Fig.11 In the case where the cam 2350-1 shown in (b) is in a high saturation state, the locking plate 2330 moves completely downward, and in the case where the cam 2350-2 is in a low saturation state, the locking plate 2330 moves completely upward. Fig.14 and Fig.15 The upward and downward movement of the locking plate 2330 according to the rotation of the cam 2350 is described in detail.

[0100] refer to Fig.11 (a), the locking plate 2330 may include a plurality of protrusions 2331 protruding at a certain height on one side thereof and grooves 2332 formed between the plurality of protrusions 2331. Fig.11 1100 is a first mode and a second mode and a third mode. In the embodiment of the present invention, three grooves 2332 are shown in (a), but the number of grooves 2332 is not limited, and the number of grooves 2332 may be determined according to the number of modes based on the exposure of the display 1100. For example, when the fully retracted state of the display 1100 is the first mode and the fully extended state of the display 1100 is the fourth mode, three grooves 2332 may be formed, or when the fully retracted state of the display 1100 is the first mode and the fully extended state of the display 1100 is the fifth mode, four grooves 2332 may be formed.

[0101] Reference together Fig.10 , the movable plate 2310 may include a blocking member 2312 on a bottom end portion thereof, and the groove 2332 of the locking plate 2330 may accommodate the blocking member 2312. That is, when the locking plate 2330 moves upward, the blocking member 2312 is located in the groove 2332. Therefore, the movable plate 2310 is locked to the locking plate 2330, thereby being prevented from moving by the protrusion 2331. In addition, when the locking plate 2330 moves downward, the blocking member 2312 is not located in the groove 2332, and therefore, the movable plate 2310 is unlocked from the locking plate 2330, thereby being able to move.

[0102] More specifically, the blocking member 2312 is positioned (ie, accommodated) in different grooves 2332 according to the exposure mode based on the display 1100, which will be referred to as Fig. 20 Describe in detail.

[0103] Fig.12 The second stopper of the support member holder in the display device according to the embodiment is shown. More specifically, Fig.12 (a) shows the situation where the locking plate moves downward, and Fig.12 (b) shows the situation where the locking plate moves upward.

[0104] Fig.12 The first bracket in corresponds to Figure 8 The first bracket in. Fig.12 The locking plate in corresponds to Fig.10 and Fig.11 (a) The locking plate. Fig.12 The blocking member in corresponds to Fig.10 The blocking member in.

[0105] refer to Fig.12, the support member holder 2300 may include a through hole 2326 and a second stopper 2327. More specifically, an oval through hole 2326 is formed on the first bracket 2320, and a second stopper 2327 connected to the locking plate 2330 may move within the through hole 2326. The second stopper 2327 is formed to be larger than the through hole 2326, and thus is not allowed to pass through the through hole 2326. Therefore, the locking plate 2330 may move upward and downward without exceeding its operating range.

[0106] For example, when the locking plate 2330 moves downward, the second stopper 2327 connected to the locking plate 2330 is caught on the other end of the through hole 2326, and thus the locking plate 2330 cannot move further downward (refer to Fig.12 Alternatively, when the locking plate 2330 moves upward, the second stopper 2327 connected to the locking plate 2330 is caught on one end of the through hole 2326, and thus the locking plate 2330 cannot move further upward (refer to Fig.12 That is, the range of upward and downward movement of the locking plate 2330 can be adjusted by adjusting the length of the through hole 2326.

[0107] Fig.13 The operating principle of the sensor in the support fixture of the display device according to the embodiment is shown. More specifically, Fig.13 (a) shows the sensor turned on, and Fig.13 (b) shows the sensor off state.

[0108] Fig.13 The sensing part corresponds to Fig.10 The sensing part in. Fig.14 The sensors in Fig. 9 and Fig.10 Sensors in . Fig.13 The locking plate in corresponds to Fig.10 and Fig.11 (a) The locking plate. Fig.13 The blocking member in corresponds to Fig.10 The blocking member in.

[0109] The sensor 2370 includes a light emitter 2371 that emits light and a light receiver 2372 that receives light from the light emitter 2371. Fig.10 , the sensing portion 2360 may be formed at one end of the second shaft 2351b where the pulley 2322 is not formed. The sensing portion 2360 includes a circular plate as a bottom surface and a side plate protruding a certain height from the edge of the circular plate in a direction perpendicular to the circular plate, and the side plate includes a hole 2361 that can be sensed by the sensor 2370.

[0110] When the shaft 2351 rotates, the sensing portion 2360 connected to one end of the shaft 2351 also rotates with the shaft 2351. More specifically, the sensing portion 2360 rotates along with the position of the hole 2361 around the same rotation axis as the shaft 2351. Fig. 9 It is shown fixed to the second bracket 2380 which is fixed to the first bracket 2320 so that the sensor 2370 is fixed in place regardless of how the sensing portion 2360 is rotated.

[0111] The sensing portion 2360 is an actuator, and the on / off of the sensor 2370 is determined according to whether the sensor 2370 passes through a hole 2361 formed on the sensing portion 2360 .

[0112] For example, Fig.13 As shown in (a), when the sensor 2370 passes through the hole 2361 formed on the sensing portion 2360, the light receiver 2372 of the sensor 2370 can receive light from the light emitter 2371, and thus the sensor 2370 is in an on state. Fig.13 As shown in (b), when the sensor 2370 does not pass through the hole 2361 formed on the sensing part 2360 according to the rotation of the sensing part 2360, more specifically, the light receiver 2372 of the sensor 2370 may not receive the light from the light emitter 2371 due to the side panel, and therefore the sensor 2370 is in an off state.

[0113] When the sensor 2370 is in the on state, the locking plate 2330 moves downward so that the blocking member 2312 is not located in the groove 2332, and thus the movable plate 2310 is not locked to the locking plate 2330. When the sensor 2370 is in the off state, the locking plate 2330 moves upward so that the blocking member 2312 is located in the groove 2332, and thus the movable plate 2310 is locked to the locking plate 2330. This is because whether to drive the second motor 2321 is controlled according to the on / off state of the sensor 2370, and therefore, the upward and downward movement of the locking plate 2330 is determined, which will refer to Fig.14 and Fig.15 Detailed description.

[0114] Fig.14 A principle of moving a locking plate downward in a support fixture of a display device according to an embodiment is shown. Fig.15 A principle of moving a locking plate upward in a support fixture of a display device according to an embodiment is shown.

[0115] Fig.14 The support fixture in corresponds to Figure 8 and Fig.10 The support fixture in the. Fig.14The locking plate in corresponds to Fig.10 and Fig.11 (a) The locking plate. Fig.14 The sensing part corresponds to Fig.13 The sensing part in. Fig.14 The sensors in Fig.13 Sensors in .

[0116] Fig.15 The support fixture in corresponds to Figure 8 and Fig.10 The support fixture in the. Fig.15 The locking plate in corresponds to Fig.10 and Fig.11 (a) The locking plate. Fig.15 The sensing part corresponds to Fig.13 The sensing part. Fig.15 The sensors in Fig.13 Sensors in .

[0117] refer to Fig.14 , which shows the operating principle of the support member holder 2300 when the movable plate 2310 changes from a locked state relative to the locking plate 2330 to an unlocked state relative to the locking plate 2330. In other words, Fig.14 It shows the situation where in order to retract or extend the display 1100, the movable plate 2310 needs to be moved.

[0118] like Fig.14 As shown, when the locking plate 2330 of the support member fixture 2300 is fully raised, the cam 2350 of the support member fixture 2300 is positioned so that the portion of the second surface 2350b having a small curvature contacts the locking plate 2330 (see Fig.11 2350-2 in a low saturation state in (b). Therefore, the sensor 2370 naturally does not pass through the hole 2361 formed on the sensing portion 2360, thereby blocking the light receiver 2372 from receiving light and is therefore in an off state (see Fig.14 (a)).

[0119] Then, in order to move the locking plate 2330, the second motor 2321 starts to rotate in the clockwise direction, which in turn causes the shaft 2351 connected to the second motor 2321 to rotate, and finally the cam 2350 and the sensing portion 2360 connected to the shaft 2351 also start to rotate in the clockwise direction (see Fig.14 (b)).

[0120] At this time, the cam 2350 rotates in a direction to bring the first surface 2350a into contact with the locking plate 2330. Since the cam 2350 is initially positioned so that the small curvature portion (i.e., large radius portion) of the second surface 2350b comes into contact with the locking plate 2330, the locking plate 2330 can be eventually moved linearly in a downward direction by the rotation of the cam 2350 in a direction to bring the first surface 2350a formed in a straight line into contact with the locking plate 2330.

[0121] When the sensor 2370 passes through the hole 2361 formed on the sensing portion 2360 during the clockwise rotation of the cam 2350 and the sensing portion 2360, the light receiver 2372 of the sensor 2370 may receive light, and thus the sensor 2370 changes from the off state to the on state (see Fig.14 (c)).

[0122] When the sensor 2370 changes from the closed state to the open state, the second motor 2321 stops rotating. However, the second motor 2321 does not stop rotating immediately. Instead, in the open state of the sensor 270, after the cam 2350 and the sensing portion 2360 further rotate 20° in the clockwise direction, the second motor 2321 stops rotating (see Fig.14 (d)).

[0123] The reason why the second motor 2321 is further operated without immediately stopping the rotation in the turned-on state of the sensor 2370 is to position the sensor 2370 at the center of the hole 2361 formed on the sensing portion 2360. Fig.14 (a), since the angle of the hole 2361 is 40°, the cam 2350 rotates an additional 20° in the clockwise direction, and then the second motor 2321 stops rotating.

[0124] That is, when the sensor 2370 is turned on, the second motor 2321 rotates further, so that the cam 2350 performs an additional operation to position the sensor 2370 at the center of the hole 2361, instead of the second motor immediately stopping the rotation.

[0125] The state in which the operation of the second motor 2321 is completely stopped is the state in which the locking plate 2330 is completely lowered, which means that the movable plate 2310 is not locked to the locking plate 2330 and can therefore move. Fig.11 (b) shows the cam 2350-1 in a high saturation state.

[0126] That is, from Fig.14 (a) to Fig.14 During (d), the cam 2350 is moved from Fig.11The state represented by the dotted line in (b) is rotated to the state represented by the solid line. In this article, the cam 2350 can rotate 121.5° relative to the first surface 2350a, such as Fig.11 Therefore, since the cam 2350 is Fig.14 (c) to Fig.14 In the process of (d), the clockwise rotation is further rotated by 20°, so that Fig.14 In the closed state of the sensor 2370 shown in (a), the cam 2350 rotates 101.5° clockwise to place the sensor 2370 in the position shown in (a). Fig.14 The open state shown in (c).

[0127] In addition, refer to Fig.11 (b), the moving length Δx of the locking plate 2330 can be determined according to the radius R1 from the rotation center of the cam 2350 to the first surface 2350a and the radius R2 from the rotation center of the cam 2350 to the small curvature portion of the second surface 2350b. The user can adjust the moving length Δx of the locking plate 2330 by adjusting R1 and R2, wherein Δx is twice the difference between R1 and R2.

[0128] For example, when the radius R1 from the rotation center of the cam 2350 to the first surface 2350a is 10.5 mm, and the radius R2 from the rotation center of the cam 2350 to the small curvature portion of the second surface 2350b is 15 mm, the distance Δx that the locking plate 2330 can move up and down is 9 mm, which is twice the difference between R1 and R2, 4.5 mm.

[0129] refer to Fig.15 , which shows the operating principle of the support member holder 2300 when the movable plate 2310 changes from the unlocked state relative to the locking plate 2330 to the locked state relative to the locking plate 2330. In other words, Fig.15 A situation is shown where the display 1100 stops moving and the movable plate 2310 also does not need to move.

[0130] like Fig.15 As shown, when the locking plate 2330 of the support member fixture 2300 is fully lowered, the cam 2350 of the support member fixture 2300 is positioned so that the large curvature portion of the second surface 2350b contacts the locking plate 2330 (see Fig.11 2350-1 in a high saturation state in (b). Therefore, the sensor 2370 naturally passes through the hole 2361 formed on the sensing portion 2360, so that the light receiver 2372 can receive light, and the sensor is in an on state (refer to Fig.15 (a)). This state can be Fig.14The state of (d) is the same.

[0131] Then, in order to move the locking plate 2330, the second motor 2321 starts to rotate in the counterclockwise direction, which in turn causes the shaft 2351 connected to the second motor 2321 to rotate together. Finally, the cam 2350 and the sensing portion 2360 connected to the shaft 2351 also start to rotate in the counterclockwise direction (see Fig.15 (b)).

[0132] When the sensor 2370 no longer passes through the hole 2361 formed on the sensing portion 2360 during the counterclockwise rotation of the cam 2350 and the sensing portion 2360, the light receiver 2372 of the sensor 2370 cannot receive light, thereby causing the sensor 2370 to change from the on state to the off state (see Fig.15 In this case, since the sensor 2370 is located at the center of the hole 2361 and the locking plate 2330 is fully lowered, the cam 2350 and the sensing portion 2360 rotate 20° counterclockwise to place the sensor 2370 in the closed state.

[0133] At this time, the cam 2350 rotates in a direction to make the first surface 2350a contact the locking plate 2330, as shown in FIG. Fig.14 Since the cam 2350 is initially positioned so that the large curvature portion (i.e., the small radius portion) of the second surface 2350b contacts the locking plate 2330, the locking plate 2330 can be linearly moved in the upward direction by the rotation of the cam 2350 in the direction in which the first surface 2350a formed in a straight line contacts the locking plate 2330 (see FIG. Fig.14 (c)).

[0134] After the sensor 2370 is turned off and then the cam 2350 rotates 101.5° in the counterclockwise direction, the second motor 2321 stops rotating (see Fig.15 (d)). Fig.11 (b), the cam 2350 can be in a state where the locking plate 2330 is fully lowered (high saturation state) and a state where the locking plate 2330 is fully raised (low saturation state). When rotating from the fully lowered state to the fully raised state, the cam 2350 rotates so that the first surface 2350a rotates by an angle of 101.5°.

[0135] Therefore, when the cam 2350 has rotated 20° counterclockwise, the sensor 2370 Fig.15 , and thus the cam 2350 only needs to be rotated an additional 101.5° counterclockwise to fully raise the locking plate 2330 after the sensor 2370 is placed in the closed state.

[0136] That is, in the off state of the sensor 2370, after the cam 2350 rotates 101.5° in the counterclockwise direction, the second motor 2321 stops rotating. The state in which the second motor 2321 completely stops rotating is the fully raised state of the locking plate 2330, which means that the movable plate 2310 is locked to the locking plate 2330 and thus cannot be moved. The cam 2350 at this time refers to Fig.11 (b) shows the cam 2350-2 in a low saturation state.

[0137] Fig.16 A spring in a support fixture of a display device according to an embodiment is shown. Fig.17 The operating principle of the spring in the display device according to the embodiment is shown. More specifically, Fig.17 (a) shows the state where the locking plate is fully lowered, and Fig.17 (b) shows a state where the locking plate is fully raised.

[0138] Fig.16 The support fixture in corresponds to Figure 8 and Fig. 9 The support fixture in the. Fig.17 The support fixture in corresponds to Figure 8 and Fig. 9 The support fixture in the.

[0139] refer to Fig.16 , the support member holder 2300 may include a spring 2335 that provides elastic force in the moving direction of the locking plate 2330. More specifically, one end of the spring 2335 may be connected to the locking plate 2330, and the other end may be connected to the plate 2340.

[0140] refer to Fig.17 , the operating principle of spring 2335 will be described in detail.

[0141] like Fig.17 As shown in (a), when the locking plate 2330 moves upward, the cam 2350 is rotated by the driving force of the second motor 2321 while overcoming the elastic force of the spring 2335. Therefore, the locking plate 2330 can be moved in the upward direction by the rotation of the cam 2350. That is, the driving force provided by the second motor 2321 overcomes the elastic force of the spring 2335.

[0142] In addition, if Fig.17 As shown in (b), when the locking plate 2330 moves downward, the spring 2335 pulls the locking plate 2330 downward and enables the locking plate 2330 to move linearly through the rotation of the cam 2350.

[0143] Fig.18A display driver in a display device according to an embodiment is shown.

[0144] Fig.18 The display driver in Figure 4 The display driver shown in FIG.

[0145] refer to Fig.18 , the display driver 1200 may include a first motor 1210, a first timing belt 1215, a worm gear unit 1220, and a worm gear unit 1230. In addition, the display winder 1300 may include a cylindrical rotating drum 1310 that can rotate around a horizontal rotation axis and wind the display 1100 around the outer peripheral surface of the cylindrical rotating drum. The display driver 1200 can move the display 1100. In addition, because when the display 1100 moves, the support member 2200 and the movable plate 2310 also move together, as shown in reference Figure 6 As described, the support member 2200 and the movable plate 2310 may also be moved by the display driver 1200 .

[0146] The first motor 1210 provides power to move the display winder 1300. The first motor 1210 may be connected to the rotating drum 1310 and rotate the rotating drum 1310. The first motor 1210 and the rotating drum 1310 may be connected using a plurality of gear parts.

[0147] like Fig.18 As shown, the first synchronous belt 1215 is connected to the rotating shaft of the first motor 1210, and the worm gear unit 1220 is connected to the first synchronous belt 1215 to rotate. The worm gear unit 1230 rotates in meshing with the worm gear unit 1220, and the worm gear unit is connected to the rotating shaft of the rotating drum 1310 to transmit the power of the first motor 1210 to the rotating drum 1310. When the rotating drum 1310 is rotated by the first motor 1210, the display 1100 is wound around or unwound from the rotating drum 1310 according to the rotating direction, thereby controlling the extension range of the display 1100.

[0148] The rotation of the first motor 1210 can be controlled by a controller (not shown). For example, the controller (not shown) can control the operation of the first motor 1210 to appropriately retract or extend the display 1100. The display unit 1000 can have areas of different sizes extending to the outside according to the mode, and the first motor 1210 can control its operation to adjust the exposure range of the display 1100 according to the mode selected by the user. The first motor 1210 can be a stepper motor or a hybrid motor. The controller (not shown) can represent an integrated controller or a head unit of the vehicle. Alternatively, the controller (not shown) can be configured to control software, hardware, a processor, or a combination thereof of the display device.

[0149] The worm gear unit 1220 includes a rod that rotates about a rotation axis parallel to the rotation axis of the first motor 1210 and a worm gear connected to the rod. The worm gear unit 1220 can be rotated by the rotation of the first motor 1210, and is operatively connected to the first motor 1210 through the first timing belt 1215. That is, the first motor 1210 can rotate the rod of the worm gear unit 1220 through the first timing belt 1215.

[0150] The worm gear unit 1230 is connected to the worm gear unit 1220 and includes a worm gear whose rotation axis is perpendicular to the rotation axis of the first motor 1210 or the worm gear unit 1220. Fig.15 As shown, the rotation axis of the worm gear unit 1230 is the same as the rotation axis of the rotating drum 1310. Therefore, when the worm gear unit 1230 is rotated by the rotation of the first motor 1210, the rotating drum 1310 is rotated.

[0151] The material of the worm gear may include polyoxymethylene (POM), and the material of the worm gear may include brass.

[0152] Fig.19 The principle of controlling exposure of a display based on rotation of a display winder in a display device according to an embodiment is shown.

[0153] Fig.19 The display winder in corresponds to Figure 4 and Fig.18 Display winder in .

[0154] refer to Fig.19 , the display unit 1000 may include a plurality of sensors 1410 and a sensing portion 1420 sensed by the plurality of sensors 1410. The sensing portion 1420 may be connected to one side surface of the rotating drum 1310 to rotate with the rotating drum and be sensed by at least one of the plurality of sensors 1410. The sensor 1410 may be fixed in place to a frame located within the housing. The side surface of the rotating drum 1310 to which the sensing portion 1420 is connected is a surface perpendicular to the rotation axis of the rotating drum 1310.

[0155] According to the rotation state of the rotating drum 1310, the sensing states of the plurality of sensors 1410 may be changed, and the operation of the first motor 1210 may be controlled based on the sensing states of the plurality of sensors 1410. In other words, based on the rotation state of the rotating drum 1310, any one of the plurality of sensors 1410 may sense a state different from the state sensed by the other sensors, and the operation of the first motor 1210 may be controlled accordingly. Therefore, the display device 100 according to the embodiment may control the extension range of the display 1100 by recognizing the rotation of the display winder 1300 via the sensing portion 1420 and the plurality of sensors 1410.

[0156] The plurality of sensors 1410 are fixed at positions where they can sense the rotation of the rotating drum 1310. The plurality of sensors 1410 may be fixed within a housing to sense a sensing portion 1420 connected to the rotating drum 1310. Thus, the sensors 1410 remain at a specific position without rotating with the rotating drum 1310.

[0157] The sensing portion 1420 rotates in connection with the rotating drum 1310, and the sensing portion 1420 is shaped so that one sensor among the plurality of sensors 1410 senses differently from the other sensors. For example, in the case where the plurality of sensors 1410 include a first sensor 1410a, a second sensor 1410b, a third sensor 1410c, and a fourth sensor 1410d, when the first sensor 1410a is in an on state by the sensing portion 1420, the second sensor 1410b to the fourth sensor 1410d are in an off state. Conversely, the first sensor 1410a may be in an off state, and the second sensor 1410b to the fourth sensor 1410d may be in an on state.

[0158] The sensing portion 1420 is connected to one surface of the rotating drum 1310 , and includes a hole 1422 which the sensor 1410 may sense.

[0159] When the rotating drum 1310 rotates, the position of the hole 1422 also rotates around the rotation axis, and when the hole 1422 passes through the sensing area 1412 of any one of the multiple sensors 1410, the sensor can detect the rotation state of the rotating drum 1310 by sensing the hole 1422. Therefore, the extension range of the display 1100 can be controlled by mapping the rotation state of the rotating drum 1310 to multiple modes.

[0160] Fig. 20 A mode based on exposure of a display in a display device according to an embodiment is shown. More specifically, Fig. 20 (a) is a perspective view showing a display device, and Fig. 20(b) is a side view showing the display device.

[0161] Fig. 20 The display device in corresponds to Figure 2 and Figure 3 Display device in.

[0162] refer to Fig. 20 , the extension range of the display 1100 in the four modes is different. Although four modes are shown in the drawings, there may be more or fewer modes. The modes can be classified into four modes, including a first mode in which the display 1100 is fully retracted and a fourth mode in which the display 1100 is fully extended. Each mode can be identified by the type and function of information displayed on the display 1100. For example, the third mode can be used for navigating the screen, and the fourth mode can be used for running a video or a game.

[0163] In the first mode, the display 1100 is retracted into the housing, wherein the display 1100 is completely wrapped around the rotating drum 1310 .

[0164] When one of the second to fourth modes is executed by user selection, the support member holder 2300 may first move the locking plate 2330 in the downward direction. Then, when it is determined that the locking plate 2330 has completely moved in the downward direction, the display driver 1200 may operate the first motor 1210 to rotate the rotating drum 1310 and extend the display 1100 from the housing 2100. When the display 1100 is extended to the outside, the support member 2200 connected to the display 1100 and the movable plate 2310 connected to the support member 2200 may also move together.

[0165] On the contrary, when the first mode is executed by user selection in one of the second to fourth modes, the support member holder 2300 may similarly first move the locking plate 2330 in the downward direction. Then, when it is determined that the locking plate 2330 has been completely moved in the downward direction, the display driver 1200 may operate the first motor 1210 to rotate the rotating drum 1310 and retract the display 1100 into the housing 2100. When the display 1100 is retracted into the housing 2100, the support member 2200 connected to the display 1100 and the movable plate 2310 connected to the support member 2200 may also move together.

[0166] In other words, when the mode is changed, the support member holder 2300 is characterized by first moving the locking plate 2330 downward before driving the display driver 1200.

[0167] In addition, the display device 100 according to the embodiment may further include a controller (not shown).

[0168] When the mode desired by the user (hereinafter, referred to as the "target mode") is the same as the currently running mode (hereinafter, referred to as the "current mode"), the controller may control to stop the retraction / extension of the display 1100, that is, to keep the display 1100 in its current state. On the contrary, when the target mode is not the same as the current mode, the controller may control the display driver 1200 to operate the first motor 1210 to retract or extend the display 1100. The controller may also control whether to operate the support fixture 2300.

[0169] For example, when the target mode is the second mode, the controller determines which mode the current mode corresponds to. When the controller determines that the current mode corresponds to the first mode, the controller can control the support member fixture 2300 to move the locking plate 2330 in the downward direction before controlling the display driver 1200. When the controller determines that the locking plate 2330 has been completely moved in the downward direction and the movable plate 2310 can be moved, the controller can control the first motor 1210 to operate in the first direction (e.g., clockwise). In addition, when the controller determines that the current mode corresponds to the third mode or the fourth mode, the controller can also control the support member fixture 2300 to move the locking plate 2330 in the downward direction before controlling the display driver 1200. When the controller determines that the locking plate 2330 has been completely moved in the downward direction and the movable plate 2310 can be moved, the controller can control the first motor 1210 to rotate in the second direction (e.g., counterclockwise). Preferably, the second direction is opposite to the first direction.

[0170] For example, when the target mode is the third mode, the controller determines which mode the current mode corresponds to. When the controller determines that the current mode corresponds to the first mode or the second mode, the controller may control the support member fixture 2300 to move the locking plate 2330 in the downward direction before controlling the display driver 1200. Then, when the controller determines that the locking plate 2330 has been completely moved in the downward direction and the movable plate 2310 can be moved, the controller may control the first motor 1210 to rotate in the first direction (e.g., clockwise). Alternatively, when the controller determines that the current mode corresponds to the fourth mode, the controller may also control the support member fixture 2300 to move the locking plate 2330 in the downward direction before controlling the display driver 1200. When the controller determines that the locking plate 2330 has been completely moved in the downward direction and the movable plate 2310 can be moved, the controller may control the first motor 1210 to rotate in the second direction (e.g., counterclockwise).

[0171] For example, when the target mode is the fourth mode, the controller determines which mode the current mode corresponds to. When the controller determines that the current mode corresponds to the first mode, the second mode, or the third mode, the controller may control the support member holder 2300 to move the locking plate 2330 in the downward direction before controlling the display driver 1200. Then, when the controller determines that the locking plate 2330 has completely moved in the downward direction and thus the movable plate 2310 can move, the controller may control the first motor 1210 to rotate in the first direction (e.g., clockwise).

[0172] In addition, when the target mode is the first mode, the controller determines which mode the current mode corresponds to. When the controller determines that the current mode corresponds to the second, third, or fourth mode, the controller may control the support member holder 2300 to move the locking plate 2330 in the downward direction before controlling the display driver 1200. Then, when the controller determines that the locking plate 2330 has completely moved in the downward direction and thus the movable plate 2310 can move, the controller may control the first motor 1210 to rotate in the second direction (e.g., counterclockwise).

[0173] When the controller determines that the target mode has been reached in any case, the controller can control the support member holder 2300 to move the locking plate 2330 in the upward direction. This provides the effect of locking the movable plate 2310 to the locking plate 2330, thereby preventing the movement of the support member 2200 and ensuring that the display 1100 is not easily damaged by external forces.

[0174] More specifically, as referenced Fig.10 and Fig.11 As described, when the locking plate 2330 moves in the upward direction, the blocking member 2312 formed on the bottom end portion of the movable plate 2310 is received in the groove 2332 formed on the locking plate 2330 , thereby locking the movable plate 2310 to the locking plate 2330 .

[0175] Reference together Fig.11 (a), for example, when the target mode is the second mode, the blocking member 2312 may be located in the first groove 2332a, thereby locking the movable plate 2310 to the locking plate 2330. Alternatively, for example, when the target mode is the third mode, the blocking member 2312 may be located in the second groove 2332b, thereby locking the movable plate 2310 to the locking plate 2330. Alternatively, for example, when the target mode is the fourth mode, the blocking member 2312 may be located in the third groove 2332c, thereby locking the movable plate 2310 to the locking plate 2330. Therefore, the interval between the grooves 2332 may be determined in proportion to the range in which the display 1100 is retracted.

[0176] According to any one of the various embodiments of the present disclosure, utilization of the interior space of a vehicle is increased by reducing the accommodation space of a display.

[0177] Furthermore, according to any one of the various embodiments of the present disclosure, the utilization rate of the display is improved by adjusting the exposure degree of the display, and power can be saved by using power only for the exposed portion of the display area.

[0178] Furthermore, according to any one of the various embodiments of the present disclosure, the flexible display may be retracted or extended from the accommodation space while being safely protected.

[0179] As described above, a detailed description of the preferred embodiments of the present disclosure has been given to enable those skilled in the art to implement and practice the present disclosure.
