Description

[0001] Cross-reference to related applications

[0002] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2023-0118371 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

[0049] Figure 1 A conventional display device is shown.

[0050] like Figure 1 As 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.

[0051] 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.

[0052] In this regard, embodiments are directed to providing a display device that supports a display and provides additional rigidity to the display.

[0053] 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.

[0054] like Figure 2 and Figure 3As 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 on the top of the display unit 1000.

[0055] 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.

[0056] Figure 4 A display unit in a display device according to an embodiment is shown.

[0057] Figure 4 The display units in Figure 2 and Figure 3 The display unit shown in FIG.

[0058] 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 .

[0059] 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.

[0060] The display 1100 may be bendable, and the radius of curvature of the display 1100 may be at least 10 mm or greater. Preferably, the radius of curvature of the display 1100 may be at least 30 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.

[0061] Figure 5 is an exploded view showing a display supporting unit in a display device according to an embodiment.

[0062] Figure 5 The display support unit in corresponds to Figure 2 and Figure 3 The display support unit shown in FIG.

[0063] refer to Figure 5 , the display supporting unit 2000 may include a housing 2100 , a door 2200 , and a door driver 2300 .

[0064] The housing 2100 may be arranged such that the door 2200 is located outside the housing and the door driver 2300 is located inside the housing, and the housing includes an opening so that the display 1100 can be extended or retracted. The housing 2100 may have a certain height so that when the display 1100 is fully or partially extended, the bottom of the display 1100 can be supported and the bottoms of the multiple side portions of the display can be supported. The height may be small for design considerations, or may be large for safety considerations of the display.

[0065] In addition, the housing 2100 may be an instrument panel (IP) of the vehicle. In other words, the IP itself may be formed as the housing 2100, wherein the door driver 2300 is located in the IP, and the display 1100 is extended or retracted through an opening, instead of adding the housing 2100. Therefore, since no additional configuration is added, various designs become available.

[0066] The door 2200 is disposed outside the housing 2100, and specifically, the door can move to enable the display 1100 to extend from or retract into the housing 2100. Specifically, the door 2200 can move linearly in the front-rear direction of the housing 2100.

[0067] For example, when the display 1100 is retracted, that is, when the display 1100 is not in use, the door 2200 is linearly moved in the forward direction of the housing 2100 to be positioned to be exposed to the outside of the housing 2100 (see FIG. Figure 2 ). When the display 1100 is extended, that is, when the display 1100 is in use, the door 2200 moves linearly in the rearward (inward) direction of the housing 2100, and due to the extension of the display 1100, the door 2200 is positioned so as not to be exposed to the outside of the housing 2100 (see Figure 3 ).

[0068] The door driver 2300 may move the door 2200 so that the door 2200 can move linearly. That is, the door driver 2300 may be located inside the housing 2100 and move the position of the door 2200 according to the retraction / extension of the display 1100. Figure 6 and Figure 7 The gate driver 2300 is described in more detail.

[0069] Figure 6 is a top view showing a gate driver in a display device according to an embodiment. Figure 7 is a perspective view showing a gate driver in a display device according to an embodiment.

[0070] Figure 6 The gate driver in Figure 5 The door driver in the Figure 7 The gates in Figure 5 The door in. Figure 7 The gate driver in Figure 5 and Figure 6 The door driver in the

[0071] refer to Figure 6 and Figure 7 , the door driver 2300 may include a plate 2310, a sliding unit 2320, a second motor 2330, a cam 2340, and a sensor 2350. The plate 2310 may be rectangular and the second motor 2330, the cam 2340, and the sensor 2350 are mounted on the plate. In addition, the sliding unit 2320 may be located on a side surface of the plate 2310.

[0072] The sliding unit 2320 may guide the door 2200 so that the door 2200 can move linearly. Fig.12 A detailed description is given of the sliding unit 2320 .

[0073] The second motor 2330 may transmit a driving force to the cam 2340, so that the door 2200 moves. The second motor 2330 may be a stepping motor or a pulse motor.

[0074] The cam 2340 may receive a driving force from the second motor 2330 and rotate by the received driving force. In this case, the cam 2340 may include a cam pulley 2341 located at the rotation center, and the cam pulley 2341 may be connected to the second motor 2330 through a second timing belt 2335, thereby transmitting the driving force of the second motor 2330 to the cam 2340.

[0075] refer to Figure 7 The cam 2340 may include a first surface 2340a formed in a straight line form and a second surface 2340b formed in a curved line form with a gradually decreasing curvature. In other words, the cam 2340 is not disc-shaped, but has a bottom surface that is straight on one side surface thereof and curved on the other side surface thereof. The cam pulley 2341 may be located at a point where the first surface 2340a and the second surface 2340b intersect.

[0076] Since the second surface 2340b is formed in a curve form with a gradually decreasing curvature, the cam 2340 can be formed to have different radii from the cam pulley 2341 serving as a rotation center to the second surface 2340b. For example, the radius R1 of the portion with a larger curvature is different from the radius R2 of the portion with a smaller curvature, and R1 is smaller than R2.

[0077] Further, the second surface 2340b makes surface contact with a portion of the door 2200, and the resulting rotation of the cam 2340 enables the door 2200 to move linearly. In addition, the cam 2340 rotates in a direction that makes the second surface 2340b make surface contact with the door 2200, but does not rotate in a direction that makes the first surface 2340a make surface contact with the door 2200. This will refer to Fig.10 and Fig.11 Describe in more detail.

[0078] The reason why the second surface 2340b of the cam 2340 is formed in a curved form with a decreasing curvature rather than a constant curved form is that rotation of the cam 2340 enables the door 2200 to move linearly.

[0079] That is, for example, when the bottom surface of the cam 2340 is formed as a circle with a constant radius, even when the cam 2340 rotates, the door 2200 may not move due to the constant radius. However, since the cam 2340 of the display device 100 according to the embodiment has a second surface 2340b formed in the form of a curve with a gradually decreasing curvature, when the cam 2340 rotates, the radius of the cam 2340 may become smaller or larger instead of being constant depending on the direction in which the cam 2340 rotates. Therefore, when the cam 2340 rotates in a direction that reduces the radius, the door 2200 can move in a backward (inward) direction of the housing 2100, and when the cam 2340 rotates in a direction that increases the radius, the door 2200 can move in a forward (outward) direction of the housing 2100. Reference will be made to Fig.10 and Fig.11 The linear movement of the door 2200 according to the rotation of the cam 2340 is described in more detail.

[0080] The door driver 2300 may include a sensor 2350. The sensor 2350 may be a photointerrupter (PI) sensor. Depending on the rotation state of the cam 2340, the sensor 2350 may or may not encounter a stopper 2342 provided in the cam 2340, which will be referred to as Figure 8 Describe in more detail.

[0081] Figure 8 1 shows a cam in a door driver of a display device according to an embodiment. More specifically, Figure 8 (a) shows a cam and a sensor, and Figure 8 (b) shows the rotation state of the cam.

[0082] Figure 8 The cam in corresponds to Figure 6 and Figure 7 The cam shown in . Figure 8The sensors in Figure 6 and Figure 7 The sensor shown in FIG.

[0083] like Figure 8 As shown in (a), the sensor 2350 is fixed to the second bracket 2355, which is fixed to the plate 2310. Therefore, regardless of the rotation of the cam 2340, the sensor 2350 is fixed in place. The cam pulley 2341 located at the rotation center of the cam 2340 is fixed to the second bracket 2355. Therefore, the cam 2340 can rotate with the fixed rotation center.

[0084] Reference together Figures 6 to 8 , the door driver 2300 may include a blocking member 2342 that is fixed to the cam 2340 and rotates with the cam 2340 when the cam 2340 rotates. Therefore, since the sensor 2350 is fixed in place on the second bracket 2355 and the blocking member 2342 is fixed in place on the cam 2340, depending on the position of the rotating cam 2340, the blocking member 2342 may pass through the sensor 2350 (the cam 2340-1 in a high saturation state) or may not pass through the sensor 2350 (the cam 2340-2 in a low saturation state), as shown in FIG. Figure 8 As shown in (b).

[0085] The blocking member 2342 is a cam actuator, and the on / off of the sensor 2350 is determined according to whether the blocking member 2342 passes through the sensor 2350, which will refer to Fig. 9 Describe in more detail.

[0086] Fig. 9 The operating principle of the sensor in the door driver of the display device according to the embodiment is shown. More specifically, Fig. 9 (a) shows the sensor in the off state, and Fig. 9 (b) shows the sensor in the on state.

[0087] Fig. 9 The cam in corresponds to Figure 8 The cam in Fig. 9 The blocking member in corresponds to Figure 8 The blocking member, and Fig. 9 The sensors in Figure 8 Sensors in .

[0088] The sensor 2350 includes a light emitter 2351 that emits light and a light receiver 2352 that receives light from the light emitter 2351. Fig. 9As shown in (a), when the sensor 2350 does not pass through the blocking member 2342, the light receiver 2352 of the sensor 2350 can receive the light from the light emitter 2351, thereby placing the sensor 2350 in the closed state. When the sensor 2350 passes through the blocking member 2342 according to the rotation of the cam 2340, the light receiver 2352 of the sensor 2350 cannot receive the light from the light emitter 2351, thereby changing the sensor 2350 to the open state.

[0089] Fig.10 A principle of opening a door in a display device according to an embodiment is shown. Fig.11 A principle of closing a door in a display device according to an embodiment is shown.

[0090] Fig.10 The shell in corresponds to Figure 5 The shell in Fig.10 The gates in Figure 7 The door in Fig.10 The gate driver in corresponds to Figure 6 and Figure 7 The door driver in the Fig.11 The shell in corresponds to Figure 5 The shell in Fig.11 The gates in Figure 7 The door in Fig.11 The gate driver in corresponds to Figure 6 and Figure 7 The door driver in the

[0091] First reference Fig.10 , which shows the operating principle of the door driver 2300 when the display 1100 changes from the retracted state to the extended state. In other words, the display device 100 is shown as changing from the retracted state to the extended state. Figure 2 The display device 100 in the Figure 3 A display device 100 in FIG.

[0092] like Fig.10 As shown, when the display 1100 is fully retracted, the door 2200 is positioned to be exposed to the outside of the housing 2100, and the cam 2340 of the door driver 2300 is positioned to make the portion of the second surface 2340b with a smaller curvature contact the door 2200, which naturally makes the sensor 2350 not encounter the blocking member 2342, so that the light receiver 2352 can receive light. Therefore, the sensor 2350 is in the closed state (see Fig.10 (a)).

[0093] To move the door 2200, the second motor 2330 then begins to rotate in a counterclockwise direction, which in turn causes the cam 2340 to begin to rotate in a counterclockwise direction (see Fig.10(b)).

[0094] At this time, the cam 2340 rotates in a direction to make the second surface 2340b contact the door 2200, as shown in FIG. Figure 7 As described. In addition, since the cam 2340 is initially positioned so that the portion of the second surface 2340b having a smaller curvature contacts the door 2200, the cam 2340 rotates in a direction in which the curvature of the second surface 2340b gradually increases. Therefore, the portion of the second surface 2340b of the cam 2340 that contacts the door 2200 is changed to a portion having a larger curvature, that is, a curved portion having a smaller radius from the rotation center (the position of the cam pulley 2341). Therefore, the door 2200 is able to move linearly in the rearward (inward) direction of the housing 2100 (see FIGS. 10( c) and 10( c)). Fig.10 (d)).

[0095] When the blocking member 2342 fixed to the cam 2340 encounters the sensor 2350 during the counterclockwise rotation of the cam, the light receiver 2352 of the sensor 2350 cannot receive light, thereby changing the sensor 2350 from the closed state to the open state (see FIG. Fig.10 (e)).

[0096] After the sensor 2350 changes from the off state to the on state, the second motor 2330 stops rotating. However, at this time, the second motor 2330 does not stop rotating immediately. On the contrary, when the sensor 2350 is in the on state, after the cam 2340 further rotates 15° in the counterclockwise direction, the second motor 2330 stops rotating (see FIG. Fig.10 (f)).

[0097] When the sensor 2350 is turned on, the second motor 2330 does not stop rotating immediately, but is further operated to position the sensor 2350 at the center of the blocking member 2342. Figure 8 (b), since the angle of the blocking member 2342 is 30°, the second motor 2330 stops rotating after the cam 2340 further rotates 15° in the counterclockwise direction.

[0098] In other words, when the sensor 2350 is turned on, the second motor 2330 does not stop rotating immediately. Instead, the second motor 2330 stops rotating after the cam 2340 further operates to position the sensor 2350 at the center of the stopper 2342.

[0099] The state in which the second motor 2330 completely stops rotating is a state in which the door 2200 is completely positioned in the rearward (inward) direction of the housing 2100 , which means that the display 1100 can extend through the opening of the housing 2100 .

[0100] Therefore, the door 2200 may have a travel length determined by the radius from the rotation center of the cam 2340 to the second surface 2340b, and the user may adjust the travel length of the door 2200 by adjusting the curvature of the curve forming the second surface 2340b. For example, the radius R1 of the portion with a larger curvature may be 34.2 mm, and the radius R2 of the portion with a smaller curvature may be 51.3 mm (see Figure 7 ).

[0101] refer to Fig.11 , which shows the operating principle of the door driver 2300 when the display 1100 changes from the extended state to the retracted state. In other words, the display device 100 is shown as changing from the extended state to the retracted state. Figure 3 The display device 100 in the Figure 2 A display device 100 in FIG.

[0102] like Fig.11 As shown, when the display 1100 is fully extended, the door 2200 is located in the housing 2100, and the cam 2340 of the door driver 2300 is positioned so that the portion of the second surface 2340b with a large curvature contacts the door 2200, which naturally causes the sensor 2350 to encounter the blocking member 2342, thereby blocking the light receiver 2352 from receiving light. Therefore, the sensor 2350 is in the open state (see Fig.11 (a)). This state can be Fig.10 The state is the same as shown in (f).

[0103] When the display 1100 is fully retracted, the second motor 2330 begins to rotate in a clockwise direction to move the door 2200, which in turn causes the cam 2340 to begin to rotate in a clockwise direction. When the blocking member 2342 fixed to the cam 2340 no longer passes by the sensor 2350 during the clockwise rotation of the cam 2340, the light receiver 2352 of the sensor 2350 is able to receive light, thereby changing the sensor 2350 from an open state to a closed state (see FIG. 24 ). Fig.11 In this case, the sensor 2350 is located at the center of the blocking member 2342 in the fully extended state of the display 1100. Therefore, when the cam 2340 is rotated 15° in the clockwise direction, the sensor 2350 is placed in the closed state.

[0104] Since the cam 2340 rotates in a direction to make the second surface 2340b contact the door 2200, as shown in FIG. Figure 7As described above, the portion of the second surface 2340b having a large curvature contacts the door 2200 at the initial position of the cam 2340, so the cam 2340 rotates in the direction in which the curvature of the second surface 2340b gradually decreases. This causes the portion in contact with the door 2200 to change to the portion of the second surface 2340b of the cam having a small curvature, that is, the curved portion having a larger radius from the rotation center (the position of the cam pulley 2341). Therefore, the door 2200 can move linearly in the forward (outward) direction of the housing 2100 (see Fig.11 (c) to Fig.11 (e)).

[0105] After the sensor 2350 is turned off, the second motor 2330 rotates the cam 2340 219.5° in the clockwise direction and then stops rotating (see Fig.11 (f)). Figure 8 (b), the cam 2340 can be in a state where the door 2200 is located inside the housing 2100 (a high saturation state, hereinafter referred to as the "first state") and an exposed state where the door 2200 is located outside the housing 2100 (a low saturation state, hereinafter referred to as the "second state"). When the cam 2340 rotates from the first state to the second state, the cam 2340 rotates so that the first surface 2340a can rotate by an angle of 234.5°.

[0106] Therefore, due to Fig.10 In (b), when the cam 2340 has rotated 15° in the clockwise direction, the sensor 2350 has changed to the closed state, so after the sensor 2350 is closed, the cam 2340 only needs to rotate an additional angle of 219.5° in the clockwise direction to change to the second state.

[0107] In other words, when the sensor 2350 is turned off, after the cam 2340 rotates 219.5° in the clockwise direction, the second motor 2330 stops rotating. The state in which the second motor 2330 stops rotating is a state in which the door 2200 is completely located in the forward (outward) direction of the housing 2100, which means that the opening of the housing 2100 is closed by the door 2200.

[0108] Fig.12 A sliding unit in a display device according to an embodiment is shown.

[0109] Fig.12 The sliding unit in corresponds to Figure 6 The sliding unit in .

[0110] refer to Fig.12 The sliding unit 2320 may include a connecting fixing member 2321 , a first sliding member 2322 , a first bracket 2324 and a second sliding member 2323 .

[0111] The connecting fixture 2321 may be fixedly connected to the door 2200 and move with the door 2200 when the door 2200 moves. The connecting fixture 2321 may be screwed to the door 2200. The first sliding member 2322 is fixed to the connecting fixture 2321. More specifically, the connecting fixture 2321 may be shaped like Wherein, the first portion and the second portion intersect at a right angle, and wherein the first portion may be fixedly connected to the door 2200 and the second portion may be fixedly connected to the first sliding member 2322 .

[0112] The first bracket 2324 may be fixedly connected to the housing 2100 and remain fixed regardless of the movement of the door 2200. The first bracket 2324 may be screwed to the housing 2100. The second slide 2323 is fixed to the first bracket 2324. More specifically, the first bracket 2324 may be track-shaped, and the second slide 2323 may be fixedly connected to the inside of the track-shaped first bracket 2324.

[0113] The first sliding member 2322 is connected to be able to slide inside the second sliding member 2323. Thus, when the door 2200 is linearly moved due to the rotation of the cam 2340, the connecting fixture 2321 and the first sliding member 2322 fixedly connected to the connecting fixture 2321 slide inside the second sliding member 2323 as the door 2200 moves linearly, thereby enabling the linear movement of the door 2200. In addition, the first bracket 2324 fixed to the housing 2100 and the second sliding member 2323 fixedly connected to the first bracket 2324 will not move due to the movement of the door 2200, thereby enabling the door 2200 to move a predetermined travel length without deviation.

[0114] Fig.13 A spring in a door driver of a display device according to an embodiment is shown. Fig.14 The operating principle of the spring in the display device according to the embodiment is shown. More specifically, Fig.14 (a) shows a state where the door is located outside the housing, and Fig.14 (b) shows a state where the door is located inside the housing.

[0115] Fig.13 The gate driver in corresponds to Figure 6 and Figure 7 The door driver in the Fig.14 The gate driver in corresponds to Fig.13 The door driver in the

[0116] refer to Fig.13, the door driver 2300 may include a spring 2315 that provides elastic force in the moving direction of the door 2200. More specifically, one end of the spring 2315 may be connected to the connecting fixture 2321, and the other end of the spring may be connected to the plate 2310. Fig.12 As shown, the connecting fixture 2321 may be shaped, wherein the first portion and the second portion intersect at a right angle, and the spring 2315 can be fixedly connected to the second portion fixedly connected to the first sliding member 2322.

[0117] refer to Fig.14 , the operating principle of spring 2315 will be described in more detail.

[0118] like Fig.14 As shown in (a), when the door 2200 is located outside the shell 2100 and moves inward, the spring 2315 pulls the door 2200 through the connecting fixture 2321 and is thus pulled into the shell 2100, thereby enabling the door 2200 to move linearly through the rotation of the cam 2340.

[0119] In addition, if Fig.14 As shown in (b), when the door 2200 is located inside the housing 2100 and moves outward, the cam 2340 can rotate while overcoming the elastic force of the spring 2315 in view of the driving force of the second motor 2330, and thus, the rotation of the cam 2340 enables the door 2200 to move linearly. That is, the driving force provided by the second motor 2330 overcomes the elastic force of the spring 2315.

[0120] Fig.15 A display driver in a display device according to an embodiment is shown.

[0121] Fig.15 The display driver in Figure 4 The display driver shown in FIG.

[0122] refer to Fig.15 , 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 an outer circumferential surface of the cylindrical rotating drum.

[0123] The first motor 1210 provides power to move the display winder 1300. The first motor 1210 may be connected to the rotating drum 1310 to rotate the rotating drum 1310. A plurality of gear parts may be used to connect the first motor 1210 and the rotating drum 1310.

[0124] like Fig.15 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.

[0125] 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 area in which the display unit 1000 extends to the outside can have different sizes 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.

[0126] The worm gear unit 1220 includes a rod rotating 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 may 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 may rotate the rod of the worm gear unit 1220 through the first timing belt 1215.

[0127] 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.

[0128] The material of the worm gear may include polyoxymethylene (POM), and the material of the worm gear may include brass.

[0129] Fig.16 The process of extending a display in a display device according to an embodiment is shown. More specifically, Fig.16 (a) shows a state where the door is located outside the housing, Fig.16 (b) shows a state where the door is located inside the housing, and Fig.16 (c) shows a state in which the display is extended, wherein the door is located inside the housing.

[0130] Fig.16 The display device in corresponds to Figure 2 and Figure 3 Display device in. Fig.16 The display driver in Fig.15 Display driver in. Fig.16 The shell in corresponds to Figure 5 The shell in. Fig.16 The gates in Figure 5 The door in. Fig.16 The gate driver in Figures 5 to 7 The door driver in the

[0131] refer to Fig.16 , an operation principle of the display device 100 according to an embodiment will be described.

[0132] As reference Fig.10 As described above, when the display 1100 is fully retracted, the door 2200 is located outside the housing 2100. That is, the opening through which the display 1100 can be extended or retracted can be closed by the door 2200 (see Fig.16 (a)).

[0133] When the display 1100 in the fully retracted state is extended by the user, the door driver 2300 is driven before the display driver 1200 is driven to extend the display 1100. In other words, before the display 1100 is extended, the door driver 2300 moves the door 2200 in the inward direction of the housing 2100 (see FIG. Fig.16 (b)). Reference Fig.10 The principle of the moving door 2200 is described.

[0134] When the door 2200 is completely moved in the inward direction of the housing 2100, the display driver 1200 drives the display 1100 in the extending direction (see FIG. Fig.16 (c)). Reference has been made to Fig.15 The operating principle of driving display 1100 is described.

[0135] Fig.16 (a) to Fig.16 (c) shows the change of the display 1100 from the retracted state to the extended state in this order, and shows the change of the display 1100 from the extended state to the retracted state in the reverse order.

[0136] Therefore, when the display 1100 changes from the extended state to the retracted state, the display 1100 is first fully retracted by the display driver 1200 (see FIG. Fig.16 (b)), then the door driver 2300 moves the door 2200 in the outward direction of the housing 2100 (see Fig.16 (a)).

[0137] Fig.17 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.

[0138] Fig.17 The display winder in corresponds to Figure 4 and Fig.15 Display winder in .

[0139] refer to Fig.17 , 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 surface of the rotating drum 1310 to rotate with the rotating drum, and may 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 refers to a surface perpendicular to the rotation axis of the rotating drum 1310.

[0140] 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.

[0141] 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.

[0142] 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 through 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.

[0143] 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.

[0144] 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.

[0145] Fig.18 A mode based on exposure of a display in a display device according to an embodiment is shown. More specifically, Fig.18 (a) is a perspective view showing a display device, and Fig.18 (b) is a side view showing the display device.

[0146] Fig.18 The display device in corresponds to Figure 2 and Figure 3 Display device in.

[0147] refer to Fig.18 , the display 1100 extends to different ranges in four modes. Although four modes are shown, there may be more or fewer modes. The modes may 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 may be identified by the type and function of information displayed on the display 1100. For example, the third mode may be used for navigating the screen, and the fourth mode may be used for running a video or a game.

[0148] In the first mode, the display 1100 is retracted into the housing by being wrapped around the rotating drum 1310 as much as possible. In addition, in the first mode, the door 2200 is located outside the housing 2100.

[0149] When one of the second to fourth modes is executed by user selection, the door driver 2300 may first move the door 2200 in the inward direction of the housing 2100. Then, when it is determined that the door 2200 is completely moved in the inward direction of the housing 2100, the display driver 1200 may operate the first motor 1210 to rotate the rotary drum 1310 and extend the display 1100 outward from the housing 2100.

[0150] In contrast, when the first mode is executed by user selection in one of the second to fourth modes, the display driver 1200 may first operate the first motor 1210 to rotate the rotating drum 1310 and retract the display 1100 into the housing 2100. Then, when it is determined that the display 1100 is fully retracted, the door driver 2300 may move the door 2200 outward from the housing 2100.

[0151] That is, unlike the display driver 1200, the gate driver 2300 is characterized by being operable to start the first mode or return to the first mode.

[0152] In addition, the display device 100 according to the embodiment may further include a controller (not shown).

[0153] 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 door driver 2300.

[0154] 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, it may control the door driver 2300 to move the door 2200 in the inward direction of the housing 2100 before controlling the display driver 1200. When the controller determines that the door 2200 is completely moved in the inward direction of the housing 2100, the controller may 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 may only control the first motor 1210 to operate in the second direction (e.g., counterclockwise) without controlling the door driver 2300. Preferably, the second direction is opposite to the first direction.

[0155] 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, the controller may first control the door driver 2300 to move the door 2200 in the inward direction of the housing 2100. Then, when the controller determines that the door 2200 is completely moved in the inward direction of the housing 2100, the controller may control the first motor 1210 to operate in the first direction (e.g., clockwise). Alternatively, when the controller determines that the current mode corresponds to the second mode, the controller may only control the first motor 1210 to operate in the first direction (e.g., clockwise) without controlling the door driver 2300. Similarly, when the controller determines that the current mode corresponds to the fourth mode, the controller may only control the first motor 1210 to operate in the second direction (e.g., counterclockwise).

[0156] 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 controller may first control the door driver 2300 to move the door 2200 in the inward direction of the housing 2100. Then, when the controller determines that the door 2200 is completely moved in the inward direction of the housing 2100, the controller may control the first motor 1210 to operate in the first direction (e.g., clockwise). Alternatively, when the controller determines that the current mode corresponds to the second mode or the third mode, the controller may only control the first motor 1210 to move in the first direction (e.g., clockwise) without controlling the door driver 2300.

[0157] 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 can control the first motor 1210 to operate in the second direction (e.g., counterclockwise), and when the controller determines that the display 1100 is fully retracted, the controller can control the door driver 2300 to move the door 2200 in the outward direction of the housing 2100.
