Description

display device

[0001] The present disclosure relates to a display device. More specifically, the display device of the present disclosure can be used for vehicles or other purposes.

[0002] As the information society develops, the demand for display devices is also increasing in various forms. In response to this, various display devices such as LCD (Liquid Crystal Display Device), PDP (Plasma Display Panel), ELD (Electro luminescent Display), VFD (Vacuum Fluorescent Display), and OLED (Organic Light Emitting Diode) have been researched and used recently. Display devices using Organic Light Emitting Diode (OLED) have the advantage of superior brightness and viewing angle compared to liquid crystal display devices, and can be implemented in an ultra-thin form because they do not require a backlight unit.

[0003] A vehicle is a means of transportation operated by a driver. To operate a vehicle, the driver needs information about its status, and the vehicle provides this information to the driver through analog or digital displays. As vehicle functionality and performance evolve, more information can be presented to the driver than ever before. Given the structural constraints of vehicles, passenger safety and space, research is being conducted on displays that provide safe and space-efficient information.

[0004] Recently, autonomous vehicles capable of operating autonomously without driver intervention are being developed. Within these vehicles, drivers and passengers can access not only the information necessary for vehicle operation, but also information for work or convenience. In-vehicle infotainment (IVI) refers to devices installed in a vehicle that provide not only driving-related information such as vehicle status and navigation, but also entertainment for the user. In-car entertainment (ICE) refers to the provision of media for users within the vehicle.

[0005] Recently, much research has been conducted on these vehicle display devices.

The display (70D) of FIG. 7 may be referred to as an extended mode display (70D).

[0057]

[0058] Referring to FIG. 8, the fixing portion (71b) of the first display (71) can protrude downward from the lower edge of the first display panel (71a) of the first display (71) and can extend along the lower edge.

[0059] The supporter (73) may be opposite the first display panel (71a) with respect to the fixing portion (71b). The supporter (73) may include a vertical part (73a), a horizontal part (73b), and a rack (73c). The vertical part (73a) may extend along the fixing portion (71b), and the fixing portion (71b) may be fixed to the vertical part (73a). The horizontal part (73b) may intersect the lower end of the vertical part (73a) and may extend along the vertical part (73a). The rack (73c) may protrude downward from the horizontal part (73b) and may extend along the horizontal part (73b). The rack (73c) may have gear teeth formed on the rear surface of the rack (73c). The rack (73c) may be referred to as a protrusion (73c).

[0060]

[0061] Referring to FIGS. 9 and 10, the first plate (74) may be positioned below the supporter (73) and may extend along the supporter (73). The first plate (74) may be a part of the housing (3, see FIG. 1) of the vehicle (1) or may be coupled to the housing (3). The upper surface of the first plate (74) may support the horizontal part (73b) of the supporter (73). A slot (74a) may be formed through the first plate (74) in the thickness direction of the first plate (74) and may extend along the first display (71) and the supporter (73). The first display (71), the supporter (73), and the slot (74a) may be curved.

[0062] The rack (73c) of the supporter (73) can be movably inserted into the slot (74a) of the first plate (74). A portion of the rack (73c) can penetrate the slot (74a) and protrude downward from the first plate (74).

[0063] The roller (73d) can be rotatably coupled to the lower surface of the horizontal part (73b) facing the first plate (74). The rotational center axis (73dx) of the roller (73d) can be parallel to the first plate (74). For example, a plurality of rollers (73da, 73db) can be arranged along the horizontal part (73b). The groove (74b) can be formed on the upper surface of the first plate (74) facing the horizontal part (73b) and can extend along the horizontal part (73b). The roller (73d) can be positioned on the groove (74b) of the first plate (74) and can roll and move. Accordingly, the supporter (73) to which the first display (71) is fixed can move smoothly and stably on the first plate (74).

[0064] The friction reducing member (73e) may extend along the horizontal part (73b). The friction reducing member (73e) may be fixed to the lower surface of the horizontal part (73b) facing the first plate (74), and may protrude from the horizontal part (73b) toward the first plate (74) and contact the first plate (74). For example, the friction reducing member (73e) may include a POM (Poly Oxy Methylene) material. For example, a plurality of friction reducing members (73ea, 73eb) may be spaced apart from each other in the width direction of the horizontal part (73b). Accordingly, the friction between the supporter (73) to which the first display (71) is fixed and the first plate (74) may be reduced.

[0065]

[0066] Referring to FIG. 11, the motor (75) may be mounted on the first plate (74) and / or the housing (3, see FIG. 1). The motor (75) may be positioned below the first plate (74) and may be an electric motor capable of adjusting the rotational direction, rotational speed, and rotational angle of the rotational shaft (75a, see FIG. 8).

[0067] The pinion (75b) can be fixed to the rotation axis (75a) of the motor (75), and the rotation axis of the pinion (75b) can be aligned in the vertical direction. The pinion (75b) can be engaged with the rack (73c) of the supporter (73).

[0068] Accordingly, when the motor (75) is driven, the supporter (73) and the first display (71) can move along the slot (74a) of the first plate (74) (see the two-way arrow in Fig. 11).

[0069] When the pinion (75b) rotates clockwise, the supporter (73) having a rack (73c) that engages with the pinion (75b) and the first display (71) fixed to the supporter (73) can rotate clockwise along the slot (74a) of the first plate (74). That is, the first display (71) can be switched from the normal mode (see FIG. 6) to the extended mode (see FIG. 7).

[0070] When the pinion (75b) rotates counterclockwise, the supporter (73) having a rack (73c) that engages with the pinion (75b) and the first display (71) fixed to the supporter (73) can be rotated counterclockwise along the slot (74a) of the first plate (74). That is, the first display (71) can be switched from the extended mode (see FIG. 7) to the normal mode (see FIG. 6).

[0071]

[0072] Referring to FIGS. 12 to 14, the first display cover (71c) of the first display (71) may be opposite the first display panel (71a) of the first display (71). The first display panel (71a) may form the back surface of the first display (71), and the first display cover (71c) may form the front surface of the first display (71).

[0073] The fixing portion (not shown) of the first display (71) can protrude downward from the lower edge of the first display panel (71a) of the first display (71) and can extend along the lower edge.

[0074] The supporter (73) may be opposite the first display panel (71a) with respect to the fixing portion, and the supporter (73) may include a vertical part (73a), a horizontal part (73b), and a pin (73c'). The vertical part (73a) may extend along the fixing portion, and the fixing portion may be fixed to the vertical part (73a). The horizontal part (73b) may intersect the lower end of the vertical part (73a) and extend along the vertical part (73a). The pin (73c') may protrude downward from the horizontal part (73b).

[0075] The first plate (74) can be positioned below the supporter (73) and can extend along the supporter (73). The first plate (74) can be a part of the housing (3, see FIG. 1) of the vehicle (1) or can be coupled to the housing (3). The upper surface of the first plate (74) can support the horizontal part (73b) of the supporter (73). The slot (74a) can be formed to penetrate the first plate (74) in the thickness direction of the first plate (74) and can extend along the first display (71) and the supporter (73). The first display (71), the supporter (73), and the slot (74a) can be curved.

[0076] The pin (73c') of the supporter (73) can be movably inserted into the slot (74a) of the first plate (74). A roller or bearing (73cc') can be rotatably coupled to the outer surface of the pin (73c'). The rotational center axis of the roller or bearing (73cc') can be parallel to the axial direction of the pin (73c'), i.e., the vertical direction. The pin (73c') can be referred to as a protrusion (73c'). Accordingly, the pin (73c') can smoothly move along the slot (74a).

[0077] The motor (75') may be mounted on the first plate (74). The motor (75') may be an electric motor capable of adjusting the rotational direction, rotational speed, and rotational angle of the rotational axis. The rotational axis of the motor (75') may be aligned horizontally.

[0078] The guide rail (751) can be mounted on the first plate (74) and can be extended in a long manner. The longitudinal direction of the guide rail (751) can intersect the longitudinal direction of the first plate (74). The motor (75') can be mounted on one side of the guide rail (751). The guide rail (751) can include a bottom (751c) placed on the upper surface of the first plate (74) and a pair of side walls (751a, 751b) protruding from both sides of the bottom (751c).

[0079] The lead screw (752) may be extended along the guide rail (751). One end of the lead screw (752) may be fixed to the rotational axis of the motor (75'). A male thread may be formed on the outer surface of the lead screw (752).

[0080] A slider (753) can be positioned on a guide rail (751) and can be penetrated by a lead screw (752). A female thread can be formed on the inner surface of a hole of the slider (753) through which the lead screw (752) penetrates, and can be engaged with the male thread of the lead screw (752). One side of the slider (753) can be movably coupled to a first side wall (751a) of the guide rail (751), and the other side of the slider (753) can be movably coupled to a second side rail (751b) of the guide rail (751). A pair of side walls (751a, 751b) can limit rotation of the slider (753).

[0081] A link (754) may connect a slider (753) and a supporter (73). The link (754) may include a first arm (754a) and a second arm (754b). One end of the first arm (754a) may be pivotally coupled to the slider (753). One end of the second arm (754b) may be pivotally coupled to the other end of the first arm (754a). The other end of the second arm (754b) may be pivotally coupled to a horizontal part (73b) of the supporter (73). The link (754) may be referred to as a foldable link (754).

[0082] Accordingly, when the motor (75') is driven, the slider (753) can perform a linear reciprocating motion along the lead screw (752), and the supporter (73) and the first display (71) connected to the slider (753) via the link (754) can move along the slot (74a) of the first plate (74).

[0083] When the slider (753) moves in the first direction (DR1), the supporter (73) connected to the slider (753) via the link (754) and the first display (71) fixed to the supporter (73) can be rotated clockwise along the slot (74a) of the first plate (74). That is, the first display (71) can be switched from the normal mode (see FIG. 6) to the extended mode (see FIG. 7).

[0084] When the slider (753) moves in the second direction (DR2), the supporter (73) connected to the slider (753) via the link (754) and the first display (71) fixed to the supporter (73) can be rotated counterclockwise along the slot (74a) of the first plate (74). That is, the first display (71) can be switched from the extended mode (see FIG. 7) to the normal mode (see FIG. 6).

[0085] In this case, a phase difference (see Pd in ​​FIG. 12) may occur between the first display (71) of the normal mode and the first display (71) of the extended mode.

[0086]

[0087] Referring to FIGS. 15 and 16, a gas spring (755) can connect a slider (753) and a supporter (73) instead of the link (754) of FIGS. 12 to 14. A guide rail (751) to which the slider (753) is movably coupled can extend along a tangential direction of a slot (74a) of the first plate (74). The gas spring (755) can include a cylinder (755a) and a rod (755b). One end of the cylinder (755a) can be fixed to the slider (753). One end of the rod (755b) can be located inside the cylinder (755a), and the other end of the rod (755b) can be rotatably coupled to the supporter (73). The eyelet (755c) can form the other end of the rod (755b), and the pin formed in the horizontal part (73b) of the supporter (73) can be rotatably inserted and coupled to the eyelet (755c).

[0088] The length of the gas spring (755) may be elastic. Specifically, a gas such as compressed nitrogen may be charged inside the cylinder (755a), and a piston (not shown) fixed to one end of a rod (755b) may be positioned inside the cylinder (755a). Alternatively, oil may also be charged inside the cylinder (755a) together with the gas. The piston may divide the internal space of the cylinder (755a) into two spaces, and the two spaces may be communicated with each other through an orifice formed in the piston. At this time, the area of ​​the first surface of the piston to which one end of the rod (755b) is fixed may be smaller than the area of ​​the second surface of the piston opposite to the first surface. Accordingly, depending on the flow of gas passing through the orifice, the rod (755b) may move in the direction inserted into the cylinder (755a) or in the opposite direction.

[0089] Accordingly, when the motor (75') is driven, the slider (753) can perform a linear reciprocating motion along the lead screw (752), and the supporter (73) and the first display (71) connected to the slider (753) via the gas spring (755) can move along the slot (74a) of the first plate (74).

[0090] And, the length of the gas spring (755) can change depending on the positions of the slider (753) and the supporter (73). The minimum length of the gas spring (755) can be formed between the normal mode and the extended mode (see the change in length (Ds) of the gas spring (755) in FIG. 16).

[0091] In this case, a phase difference may not occur between the first display (71) of the normal mode and the first display (71) of the extended mode.

[0092]

[0093] Referring to FIGS. 17 to 19, the second display cover (72c) of the second display (72) may be opposite the second display panel (72a) of the second display (72). The second display panel (72a) may form the back surface of the second display (72), and the second display cover (72c) may form the front surface of the second display (72).

[0094] The fixing portion (72b) of the second display (72) can protrude forward from the second display cover (72c) adjacent to the lower side of the second display (72).

[0095] The second rack (76) may be opposite the second display (72) with respect to the fixing member (72b). The second rack (76) may be fixed to the end of the fixing member (72b), and the second rack (76) may extend along the second display (72) from below the fixing member (72b). The second rack (76) may have gear teeth formed on the rear surface of the second rack (76). The second rack (76) may be referred to as a protrusion (76).

[0096] The second plate (77) can be positioned below the second display (72) and can extend along the second display (72). The second plate (77) can be movably coupled to the housing (3, see FIG. 1) of the vehicle (1). A slot (77a) can be formed through the plate (77) in the thickness direction of the plate (77) and can extend along the second display (72) and the second rack (76). The second display (77), the second rack (76), and the slot (77a) can be curved.

[0097] The second rack (76) can be movably inserted into the slot (77a) of the second plate (77). A portion of the second rack (76) can penetrate the slot (77a) and protrude downward from the second plate (77).

[0098] The upper surface of the first plate (74) can support the lower surface of the second display (72). The first plate (74) can be referred to as a fixed plate (74), and the second plate (77) can be referred to as a moving plate (77).

[0099] The roller (72d) can be rotatably coupled to the lower side of the second display (72) facing the first plate (74). The rotational center axis (72dx) of the roller (72d) can be parallel to the first plate (74). For example, a plurality of rollers (72d) can be arranged along the lower side of the second display (72). Accordingly, the second display (72) can move smoothly and stably on the first plate (74).

[0100] The first motor (78) can be mounted on the first plate (74) and / or the housing (3, FIGS. 1 and 2). The first motor (78) can be adjacent to the second plate (77). The rotational shaft (78a) of the first motor (78) can be an electric motor whose rotational direction, rotational speed, and rotational angle can be adjusted. The first pinion (78b) can be fixed to the rotational shaft (78a) of the first motor (78), and the rotational shaft of the first pinion (78b) can be aligned in the horizontal direction. The rotational shaft of the first pinion (78b) can be aligned in the tangential direction of the second plate (77). The first rack (77c) can protrude from the second plate (77) in the radial direction of the second plate (77). The first pinion (78b) may be positioned on the first rack (77c) and may mesh with a gear formed on the first rack (77c). The first rack (77c) may be referred to as a protrusion (77c).

[0101] Accordingly, when the first motor (78) is driven, the second display (72) coupled to the second plate (77) through the second rack (76) and the second plate (77) forming the first rack (77c) can move in a direction parallel to the first rack (77c).

[0102] When the first pinion (78b) rotates clockwise, the second plate (77) having the first rack (77c) that engages the first pinion (78b) and the second display (72) coupled to the second plate (77) can move rearward (see DRr in FIG. 19).

[0103] When the first pinion (78b) rotates counterclockwise, the second plate (77) having the first rack (77c) that engages the first pinion (78b) and the second display (72) coupled to the second plate (77) can move forward (see DRf of FIG. 19).

[0104] The second motor (79) can be mounted on the second plate (77). The second motor (79) can be mounted on one surface (e.g., the lower surface) of the second plate (77). The second motor (79) can be an electric motor capable of adjusting the rotational direction, rotational speed, and rotational angle of the rotational shaft (79a). The second pinion (79b) can be fixed to the rotational shaft (79a) of the second motor (79), and the rotational axis of the second pinion (79b) can be aligned vertically. The second pinion (79b) can be engaged with the second rack (76). For example, the auxiliary roller (79c) mounted on the second plate (77) can be opposite the second pinion (79b) with respect to the second rack (76) and can rotate about an axis aligned vertically. The auxiliary roller (79c) can contact the second rack (76), and the second rack (76) can move stably between the second pinion (79b) and the auxiliary roller (79c).

[0105] Accordingly, when the second motor (79) is driven, the second rack (76) and the second display (72) fixed to the second rack (76) can move along the slot (77a) of the second plate (77).

[0106] When the second pinion (79b) rotates counterclockwise, the second rack (76) that engages with the second pinion (79b) and the second display (72) that is fixed to the second rack (76) can rotate counterclockwise along the slot (77a) of the second plate (77). That is, the second display (72) can be switched from the normal mode (see FIG. 6) to the extended mode (see FIG. 7).

[0107] When the second pinion (79b) rotates clockwise, the second rack (76) that engages with the second pinion (79b) and the second display (72) that is fixed to the second rack (76) can rotate clockwise along the slot (77a) of the second plate (77). That is, the second display (72) can be switched from the extended mode (see FIG. 7) to the normal mode (see FIG. 6).

[0108]

[0109] Referring to FIG. 20 together with FIGS. 6 and 7, the display (70D) can be switched to normal mode or extended mode through the following mechanism.

[0110] The first and second displays (71, 72) of the display (70D) of the general mode of FIG. 6 can be overlapped front to back, and the second display (72) can be positioned in front of the first display (71).

[0111] First, the second display (72) can be rotated counterclockwise along the slot (77a) of the second plate (77) through the interlocking structure of the second pinion (79b) and the second rack (76) described above (see A1 in FIG. 6). Simultaneously or simultaneously with the rotation of the second display (72) (see A1 in FIG. 6), the first display (71) can be rotated clockwise along the slot (74a, see FIG. 17) of the first plate (74) (see A2 in FIG. 6). Next, the second display (72) can be moved rearward through the interlocking structure of the first pinion (78b) and the first rack (77c) described above (see DRr in FIG. 20 and A3 in FIG. 6), so that the center of curvature of the second display (72) can form a concentricity with the center of curvature of the first display (71). Next, the second display (72) can be rotated clockwise along the slot (77a) of the second plate (77) through the interlocking structure of the second pinion (79b) and the second rack (76) described above (see A4 of FIG. 6), and as a result, the second display (72) can be brought into close contact with and aligned with the first display (71).

[0112] Accordingly, the display (70D) can be switched from the normal mode of FIG. 6 to the extended mode of FIG. 7. The above-described mechanism can also be applied to switching the display (70D) in the normal mode of FIGS. 21 and 22, which will be described later, to the display (70D) in the extended mode of FIGS. 23 and 24.

[0113] The first and second displays (71, 72) of the display (70D) in the extended mode of FIG. 7 can be positioned on one virtual curved surface.

[0114] First, the second display (72) can be rotated counterclockwise along the slot (77a) of the second plate (77) through the interlocking structure of the second pinion (79b) and the second rack (76) described above, so that the second display (72) can be separated from the first display (71) (see B1 of FIG. 7). Next, the second display (72) can be moved forward through the interlocking structure of the first pinion (78b) and the first rack (77c) described above (see DRf of FIG. 20 and B3 of FIG. 7), so that the center of curvature of the second display (72) can be eccentric with respect to the center of curvature of the first display (71). Next, the second display (72) can be rotated clockwise along the slot (77a) of the second plate (77) through the interlocking structure of the second pinion (79b) and the second rack (76) described above (see B4 of FIG. 7). Simultaneously or simultaneously with the rotation of the second display (72), the first display (71) can be rotated counterclockwise along the slot (74a, see FIG. 17) of the first plate (74) (see B2 of FIG. 7). When the rotation of the first and second displays (71, 72) is completed, the first and second displays (71, 72) can be overlapped front to back, and the second display (72) can be positioned in front of the first display (71).

[0115] Accordingly, the display (70D) can be switched from the extended mode of FIG. 7 to the normal mode of FIG. 6. The above-described mechanism can be equally applied to switching the display (70D) in the extended mode of FIGS. 23 and 24, which will be described later, to the display (70D) in the normal mode of FIGS. 21 and 22.

[0116] Meanwhile, unlike the above and the following description, the positions of the first and second displays (71, 72) can be exchanged, and in this case, the above-described mechanism can be applied to the first and second displays (71, 72) in the opposite direction.

[0117]

[0118] Referring to FIGS. 21 and 22, the cover (5c) may cover at least a portion of the rear surface of the display (70D) in normal mode on the housing (3). The cover (5c) may be referred to as a blind (5c).

[0119] Referring to FIGS. 23 and 24, the cover (5c) may be inserted into the housing (3) and may not cover the rear surface of the display (70D). At this time, the display (70D) may be in an extended mode.

[0120]

[0121] Referring to FIGS. 25 and 26, the first plate (74) may be positioned inside the housing (3) and may be fixed to the housing (3). The supporter (73) may be coupled to the first plate (74) so ​​as to be movable in the direction of movement of the first display (71) inside the housing (3). The rack (73c) of the supporter (73) may be curved and may be convex toward the front. The rack (73c) may have gear teeth formed on the front side of the rack (73c) (see FIGS. 25 and 26). Alternatively, the rack (73c) may have gear teeth formed on the rear side of the rack (73c) (see FIG. 11).

[0122] The motor (75) can be mounted on the first plate (74), and the pinion (75b) can be fixed to the rotational axis of the motor (75). The pinion (75b) can engage with the rack (73c) of the supporter (73), and the supporter (73) can move in response to the rotation of the pinion (75b). The pinion (75b, see FIGS. 25 and 26) engaging with the front of the rack (73c) can rotate in a first rotational direction to move the supporter (73) in a specific direction, and the pinion (75b, see FIG. 11) engaging with the rear of the rack (73c) can rotate in a second rotational direction opposite to the first rotational direction to move the supporter (73) in the specific direction. The auxiliary roller (74c) mounted on the first plate (74) can be opposite the pinion (75b) with respect to the rack (73c) and can support the movement of the rack (73c) by contacting the rack (73c).

[0123] When the pinion (75b) rotates counterclockwise, the supporter (73) having a rack (73c) that engages with the pinion (75b) and the first display (71) fixed to the supporter (73) can rotate clockwise. That is, the first display (71) can be switched from the normal mode (see FIGS. 21 and 22) to the extended mode (see FIGS. 23 and 24).

[0124] When the pinion (75b) rotates clockwise, the supporter (73) having a rack (73c) that engages with the pinion (75b) and the first display (71) fixed to the supporter (73) can rotate counterclockwise. That is, the first display (71) can be switched from the extended mode (see FIGS. 23 and 24) to the normal mode (see FIGS. 21 and 22).

[0125]

[0126] Referring to FIGS. 27 and 28, the sensor (73S) can detect the position of the supporter (73). For example, the sensor (73S) may be a photo sensor and may include a light emitting portion (73Sa) and a light receiving portion (73Sb) facing each other. However, the type of the sensor (73S) is not limited thereto, and various types of sensors such as a proximity sensor, a hall sensor, and a limit switch can detect the position of the supporter (73). The sensor (73S) including the light emitting portion (73Sa) and the light receiving portion (73Sb) may have an overall horseshoe shape. The light emitting portion (73Sa) can provide light in an infrared wavelength range toward the light receiving portion (73Sb).

[0127] Referring to Fig. 27, a protrusion (73P) may be formed at one end of the supporter (73). When the protrusion (73P) is positioned between the light-emitting portion (73Sa) and the light-receiving portion (73Sb), the light of the light-emitting portion (73Sa) may be blocked by the protrusion (73P), and as a result, the first sensor (73S1) may detect the position of the supporter (73). Accordingly, the control unit may control the operation of the motor (75) based on the information obtained from the first sensor (73S1). For example, the control unit may stop the movement of the supporter (73) when the protrusion (73P) is detected by the first sensor (73S1).

[0128] Referring to Fig. 28, a protrusion may be formed at the other end of the supporter (73). If the protrusion is positioned between the light-emitting portion (73Sa) and the light-receiving portion (73Sb), the light of the light-emitting portion (73Sa) may be blocked by the protrusion, and as a result, the second sensor (73S2) may detect the position of the supporter (73). Accordingly, the control unit may control the operation of the motor (75) based on the information obtained from the second sensor (73S2). For example, the control unit may stop the movement of the supporter (73) if the protrusion is detected by the second sensor (73S2).

[0129]

[0130] Referring to FIG. 29, a plurality of rollers (73d) can be rotatably coupled to a horizontal part (73b) of a supporter (73) and can move along a first plate (74). A rotational center axis (73dx) of the rollers (73d) can be parallel to the first plate (74). Accordingly, the supporter (73) to which the first display (71) is fixed can move smoothly and stably along the slot (74a) of the first plate (74).

[0131]

[0132] Referring to FIGS. 30 and 31, the second plate (77) may be positioned inside the housing (3) and may be positioned above the first plate (74). The second plate (77) may be coupled to the housing (3) so as to be movable back and forth. For example, roller(s) mounted on the second plate (77) may roll on the first plate (74), thereby facilitating the back and forth movement of the second plate (77). The second plate (77) may be curved and may be convex toward the front. The first rack (77c) may be fixed to the lower surface of the second plate (77) and may extend in the radial direction (i.e., the back and forth direction) of the second plate (77). The first rack (77c) may have gear teeth formed on the side surface of the first rack (77c).

[0133] The first motor (78) can be mounted on the first plate (74), and the first pinion (78b) can be fixed to the rotational axis of the first motor (78). The first pinion (78b) can be engaged with the first rack (77c), and the second plate (77) can move in response to the rotation of the first pinion (78b).

[0134] When the first pinion (78b) rotates clockwise, the second plate (77) to which the first rack (77c) engaging the first pinion (78b) is fixed and the second display (72) coupled to the second plate (77) can move rearward (see DRr in FIG. 28). The second plate (77) and the second display (72) can move rearward as part of a process of switching the mode of the display (70D) from the normal mode (see FIGS. 21 and 22) to the extended mode (see FIGS. 23 and 24) (see A2 in FIG. 6).

[0135] When the first pinion (78b) rotates counterclockwise, the second plate (77) to which the first rack (77c) engaging the first pinion (78b) is fixed and the second display (72) coupled to the second plate (77) can move forward (see DRf in FIG. 28). The second plate (77) and the second display (72) can move forward as part of a process of switching the mode of the display (70D) from the extended mode (see FIGS. 23 and 24) to the normal mode (see FIGS. 21 and 22) (see B3 in FIG. 7).

[0136] The sensor (77S) can be mounted on the first plate (74) and can detect the position of the second plate (77). For example, the sensor (77S) can be a photo sensor and can include a light emitting portion (77Sa) and a light receiving portion (77Sb) facing each other. However, the type of the sensor (77S) is not limited thereto, and various types of sensors such as a proximity sensor, a hall sensor, and a limit switch can detect the position of the second plate (77). The sensor (77S) having the light emitting portion (77Sa) and the light receiving portion (77Sb) can have an overall horseshoe shape. The light emitting portion (77Sa) can provide light in the infrared wavelength range toward the light receiving portion (77Sb). The sensor (77S) can include a first sensor (77S1) and a second sensor (77S2) spaced forward from the first sensor (77S1). The protrusion (77P) can protrude from the lower surface of the second plate (77).

[0137] When the protrusion (77P) is positioned between the light emitting portion (77Sa) and the light receiving portion (77Sb), the light of the light emitting portion (77Sa) can be blocked by the protrusion (77P), and as a result, the first sensor (77S1) can detect the position of the supporter (73). Accordingly, the control unit can adjust the operation of the first motor (78) based on the information obtained from the first sensor (77S1). For example, the control unit can stop the rearward movement of the second plate (77) when the protrusion (77P) is detected by the first sensor (77S1).

[0138] When the protrusion (77P) is positioned between the light emitting portion (77Sa) and the light receiving portion (77Sb), the light of the light emitting portion (77Sa) can be blocked by the protrusion (77P), and as a result, the second sensor (77S2) can detect the position of the supporter (73). Accordingly, the control unit can adjust the operation of the first motor (78) based on the information obtained from the first sensor (77S1). For example, the control unit can stop the forward movement of the second plate (77) when the protrusion (77P) is detected by the second sensor (77S2).

[0139]

[0140] Referring to FIGS. 32 and 33, the second rack (76) may be curved along the slot (77a) of the second plate (77) and may be movably inserted into the slot (77a) of the second plate (77). The second rack (76) may be fixed to the second display (72) via the fixing member (72b). For example, roller(s) mounted on the fixing member (72b) may roll on the second plate (77), thereby facilitating the circumferential movement of the second display (72). The second rack (76) may have gear teeth formed on the front surface of the second rack (76). Alternatively, the second rack (76) may also have gear teeth formed on the rear surface of the second rack (76) (see FIG. 19).

[0141] The second motor (79) can be mounted on the second plate (77), and the second pinion (79b) can be fixed to the rotational axis of the second motor (79). The second pinion (79b) can be engaged with the second rack (76), and the second rack (76) can move in response to the rotation of the second pinion (79b). The second pinion (79b, see FIGS. 30 and 31) engaged with the front of the second rack (76) can rotate in a first rotational direction to move the second rack (76) in a specific direction, and the second pinion (79b, see FIG. 19) engaged with the rear of the second rack (76) can rotate in a second rotational direction opposite to the first rotational direction to move the second rack (76) in the specific direction. The auxiliary roller (79c) mounted on the second plate (77) can be opposite the second pinion (79b) with respect to the second rack (76) and can support the movement of the second rack (76) by contacting the second rack (76).

[0142] When the second pinion (79b) rotates clockwise, the second rack (76) that engages with the second pinion (79b) and the second display (72) that is fixed to the second rack (76) can rotate counterclockwise. That is, the second display (72) can be switched from the normal mode (see FIGS. 21 and 22) to the extended mode (see FIGS. 23 and 24).

[0143] When the second pinion (79b) rotates counterclockwise, the second rack (76) that engages with the second pinion (79b) and the second display (72) that is fixed to the second rack (76) can rotate clockwise. That is, the second display (72) can be switched from the extended mode (see FIGS. 23 and 24) to the normal mode (see FIGS. 21 and 22).

[0144]

[0145] Referring to Fig. 34, the sensor (72S) can detect the position of the fixed portion (72b). For example, the sensor (72S) may be a photo sensor and may include a light emitting portion and a light receiving portion facing each other. However, the type of the sensor (72S) is not limited thereto, and various types of sensors such as a proximity sensor, a hall sensor, and a limit switch can detect the position of the fixed portion (72b). The sensor (72S) including the light emitting portion and the light receiving portion may have an overall horseshoe shape. The light emitting portion may provide light in an infrared wavelength range toward the light receiving portion.

[0146] A protrusion may be formed on one side of the fixing portion (72b). When the protrusion is positioned between the light-emitting portion and the light-receiving portion, light from the light-emitting portion may be blocked by the protrusion, and as a result, the sensor (72S) may detect the position of the fixing portion (72b). Accordingly, the control portion may control the operation of the second motor (79) based on the information obtained from the sensor (72S). For example, the control portion may stop the movement of the fixing portion (72b) when the protrusion is detected by the sensor (72S).

[0147]

[0148] Referring to FIGS. 32 and 35, the vertical racks (51, 52) can be vertically extended and vertically movably coupled to the housing (3). The top (3T) of the housing (3) can have a hole (3h) through which the vertical racks (51, 52) pass. The motor (5) can be mounted inside the housing (3) via a bracket (5a). The motor (5) can be an electric motor capable of adjusting the rotational direction, rotational angle, and rotational speed of the rotational shaft. The pinion (5b) can be fixed to the rotational shaft of the motor (5) and can be engaged with the vertical racks (51, 52). Accordingly, when the motor (5) is driven, the vertical racks (51, 52) can be raised or lowered by the pinion (5b). The first assembly of the motor (5), the pinion (5b), and the first vertical rack (51) and the second assembly of the motor (5), the pinion (5b), and the second vertical rack (52) can be provided left and right.

[0149] The top frame (53) can extend in a direction intersecting the vertical racks (51, 52) and can be fixed to the top of the vertical racks (51, 52). The top frame (53) can be curved along the display (70D). The first vertical rack (51) can be adjacent to one end of the top frame (53), and the second vertical rack (52) can be adjacent to the other end of the top frame (53).

[0150] The cover (5c) can extend in a direction intersecting the vertical racks (51, 52) and can be joined to the vertical racks (51, 52) below the top frame (53). The cover (5c) can be curved along the top frame (53). The cover (5c) can rise or fall together with the vertical racks (51, 52). The cover (5c) can include a first grille (54), a second grille (55), a third grille (56), a first spine (57), and a second spine (58).

[0151] The first spine (57) may be located at the rear of the first vertical rack (51) and may be coupled to the lower side of the top frame (53).

[0152] The second spine (58) may be located at the rear of the second vertical rack (52) and may be coupled to the lower side of the top frame (53).

[0153] Each of the first and second spines (57, 58) may include a plurality of disks (5Cd) arranged along a vertical direction. The disks (5Cd) may extend forward and backward. Rollers (5Ce) may be mounted on one or both sides of the disks (5Cd) and may rotate on the rear surface of the vertical racks (51, 52). The disk (5Cd) located at the lowest position among the plurality of disks (5Cd) may be mounted on the upper surface of the horizontal frame inside the housing (3). Accordingly, since the position of the disk (5Cd) located at the lowest position is fixed, the gap (Da) between the plurality of disks (5Cd) may be reduced as the vertical racks (51, 52) and the top frame (53) descend.

[0154] The first grill (54) may form one end of the cover (5c) and may be coupled to the lower side of the top frame (53). The third grill (56) may form the other end of the cover (5c) and may be coupled to the lower side of the top frame (53). The second grill (55) may be positioned between the first grill (54) and the third grill (56) and may be coupled to the lower side of the top frame (53). The first spine (57) may be positioned between the first grill (54) and the second grill (55), and the second spine (58) may be positioned between the second grill (55) and the third grill (56).

[0155] Each of the first to third grilles (54, 55, 56) may include a plurality of blades (5Ca) and a plurality of links (5Cb). The blades (5Ca) may extend along the top frame (53) and may be curved. The links (5Cb) may extend in a direction intersecting the blades (5Ca), and the rear ends of each of the links (5Cb) may be pivotally coupled to each of the blades (5Ca). For example, the length of the blade (5Ca) of the second grille (55) may be greater than the lengths of the blades (5Ca) of the first and third grilles (54, 56).

[0156] The blades (5Ca) of the first grill (54) can be connected to one side of the first spine (57) via links (5Cb). The front end of each of the links (5Cb) can be pivotally coupled to one side of each of the disks (5Cd) of the first spine (57).

[0157] The blades (5Ca) of the second grill (55) can be connected to the other side of the first spine (57) via links (5Cb). The front end of each of the links (5Cb) can be pivotally coupled to the other side of each of the disks (5Cd) of the first spine (57). The blades (5Ca) of the second grill (55) can be connected to one side of the second spine (58) via links (5Cb). The front end of each of the links (5Cb) can be pivotally coupled to one side of each of the disks (5Cd) of the second spine (58).

[0158] The blades (5Ca) of the third grill (56) can be connected to the other side of the second spine (58) via links (5Cb). The front end of each of the links (5Cb) can be pivotally coupled to the other side of each of the disks (5Cd) of the second spine (58).

[0159] The blade (5Ca) positioned at the lowest of each of the first to third grills (54, 55, 56) may be mounted on the upper surface of a horizontal frame inside the housing (3). The horizontal frame on which the blade (5Ca) positioned at the lowest may be mounted may be the same as the horizontal frame on which the disk (5Cb) positioned at the lowest may be mounted. Accordingly, since the position of the blade (5Ca) positioned at the lowest is fixed, the gap (Db) between the plurality of blades (5Ca) may be reduced as the vertical racks (51, 52) and the top frame (53) are lowered.

[0160] Accordingly, the cover (5c) can be inserted into the interior of the housing (3) through the hole (3h) of the housing (3) while descending from the rear of the display (70D), thereby gradually opening the rear of the display (70D). The cover (5c) can be exposed to the exterior of the housing (3) through the hole (3h) of the housing (3) while rising from the rear of the display (70D), thereby gradually covering the rear of the display (70D).
