The sunshade (45) can be wound or unwound as the motor shaft (212c), power bush (216), motor adapter (215) and / or the roller body (72a) rotate relative to the rear cap assembly (221, 222), motor (212a), gear set (212b), motor pipe (211) and / or front cap (213) fixed to the roller bracket (24). Power provided by the motor (61) and gearbox (62) is transmitted to the belt (32, see FIG. 18) so that the bar (40) moves upward together with the top of the sunshade (45), and the roller body (72a) can unwrap the sunshade. When power provided by the motor (61) and gearbox (62) is transmitted to the belt (32, see FIG. 18) and the bar (40) moves downward together with the top of the sunshade (45), the roller body (72a) can wind the sunshade (45). A control unit (not shown) can control the range over which the sunshade (45) covers the display panel (11) (11, see FIG. 10) by independently controlling the motor (61) and the motor (212a).

[0151]

[0152] Referring to FIG. 45, the main roller and the sub-roller can be positioned on the base frame. The shading film can be wound or unwound on the main roller and guided by the sub-roller.

[0153] Specifically, the sunshade can be wound onto a main roller and supported by a sub-roller. As the sunshade is unwound from the main roller, it can be guided by the sub-roller. The sunshade can be moved to the front of the housing frame by the sub-roller. The sunshade can cover the front of the housing frame.

[0154] More specifically, when the bar rises, the sunshade can be unwound from the main roller and guided between the housing frame and the display (10) by the sub-roller. When the bar lowers, the sunshade can be wound onto the main roller and guided toward the main roller by the sub-roller. The main roller may be referred to as a roller. The sub-roller may be referred to as an auxiliary roller, an idle roller (73, idle roller), or an idler (73, idler).

[0155] The sub-roller can change the direction of travel of the shading screen. For example, the sub-roller can change the direction of travel of the shading screen from moving from the main roller toward the sub-roller (e.g., forward) to a direction from the sub-roller toward the bar (e.g., upward or a second direction).

[0156]

[0157] With reference to FIGS. 45 and FIGS. 46, the sub-roller (73) will be described in detail.

[0158] A sub-roller (73) may be provided between the main roller (72) and the bar (40). For example, the sub-roller (73) may be provided in front of the main roller (72). The sub-roller (73) may extend along one side of the display (10). For example, the sub-roller (73) may extend in the left-right direction or in the first direction.

[0159] The sub-roller (73) may include a sub-roller body (73a) that changes the direction of travel of the sunshade (45), a sub-bearing (732) within one end of the sub-roller body (73a), and a sub-fixing cap (734) that is coupled with the roller bracket (24).

[0160] The sub-roller body (73a) may be extended along one side of the display (10). For example, the sub-roller body (73a) may be extended along the left-right direction or the first direction and may have a cylindrical shape with a hollow interior. The sub-roller body (73a) may rotate around a virtual axis of rotation. The axis of rotation may pass through the hollow of the sub-roller body (73a).

[0161] The sub-roller body (73a) can guide the sunshade (45). The sub-roller body (73a) can change the direction of travel of the sunshade (45) while rotating. The sub-roller body (73a) can come into contact with the sunshade (45). The sub-roller body (73a) can bend the sunshade (45). For example, the sunshade (45) moves along the outer surface of the rotating sub-roller body (73a), and the direction of travel of the sub-roller body (73a) can be changed from forward to upward.

[0162] The sub-roller body (73a) can be electrically connected to the sunshade (45). The sub-roller body (73a) may include a conductive material. The sub-roller body (73a) may include a metal such as a steel alloy (e.g., stainless steel, tool steel, high-speed steel), a non-ferrous alloy (e.g., copper alloy, aluminum alloy, titanium alloy), a special alloy (e.g., nickel alloy, superalloy, Monel metal), or a lightweight alloy (e.g., duralumin alloy, magnesium alloy). For example, the sub-roller body (73a) may include aluminum.

[0163] The sub-roller body (73a) may include a holder portion (73b) in which a sub-bearing (732) is placed, and a seating portion (73c) that supports the sub-bearing (732). The holder portion (73b) may be recessed (732d) from the inner surface of the sub-roller body (73a). The holder portion (73b) may be recessed (732d) along the inner circumference of the sub-roller body (73a), and the thickness of the holder portion (73b) may be smaller than the thickness of the sub-roller body (73a). The holder portion (73b) may extend along the circumference of the inner circumference of the sub-roller body (73a). A step may be formed between the inner surface of the holder portion (73b) and the inner surface of the sub-roller body (73a). For example, the holder portion (73b) may have a step lower than the inner surface of the sub-roller body (73a).

[0164] The seating portion (73c) can correspond to the step between the inner surface of the holder portion (73b) and the sub-roller body (73a). The seating portion (73c) can support the sub-bearing (732) and can fix the position of the sub-bearing (732).

[0165] The sub-roller body (73a) may further include a fastening hole (73h) penetrating in the thickness direction. The fastening hole (73h) may penetrate the outer surface and the inner surface of the sub-roller body (73a).

[0171] The bearing body (732a) may have a donut shape with a hollow center. One side and / or the other side of the bearing body (732a) may be flat. The outer diameter of the bearing body (732a) may correspond to the inner diameter of the holder portion (73b) of the sub-roller body (73a). By doing so, the bearing body (732a) can be inserted into the holder portion (73b) of the sub-roller body (73a).

[0172] The outer rim (732b) may protrude from one side of the bearing body (732a). The outer rim (732b) may extend along the outer circumference of the bearing body (732a). The outer rim (732b) may be a ring-shaped protrusion protruding from one side of the bearing body (732a).

[0173] The inner rim (732c) may protrude from one side of the bearing body (732a). The inner rim (732c) may extend along the inner circumference of the bearing body (732a). The inner rim (732c) may be a ring-shaped protrusion protruding from one side of the bearing body (732a).

The inner rim (732c) may be located around the hollow portion (732H) of the bearing body (732a).

[0174] The recess (732d) may be located between the outer rim (732b) and the inner rim (732c). The recess (732d) may have a lower step than the outer rim (732b). Also, the recess (732d) may have a lower step than the inner rim (732c).

[0175] The sub-fixing cap (734) can be coupled to the sub-bearing (732). The sub-fixing cap (734) can be coupled to the roller bracket (24). For example, one side of the sub-fixing cap (734) can be inserted and coupled to the sub-bearing (732), and the other side of the sub-fixing cap (734) can be coupled to the roller bracket (24).

[0176] The sub-fixing cap (734) can be electrically connected to the sub-bearing (732). Through this, the sub-fixing cap (734) can be electrically connected to the sub-roller body (73a) and the sunshade (45) via the sub-bearing (732).

[0177] Additionally, the sub-fixing cap (734) can be electrically connected to the roller bracket (24). Through this, the sub-fixing cap can electrically connect the roller bracket (24), the sub-bearing (732), the sub-roller body (73a), and the sunshade (45).

[0178] The sub-fixing cap (734) may include a conductive material. The sub-fixing cap (734) may include a metal such as a steel alloy (e.g., stainless steel, tool steel, high-speed steel), a non-ferrous alloy (e.g., copper alloy, aluminum alloy, titanium alloy), a special alloy (e.g., nickel alloy, superalloy, Monel metal), or a lightweight alloy (e.g., duralumin alloy, magnesium alloy). For example, the sub-fixing cap (734) may include aluminum.

[0179] The sub-fixing cap (734) may include a cap body (734a) disposed on one side of a bearing body (732a), a cap shaft (734b) inserted into a hollow portion (732H) of the bearing body (732a), and a cap mount (734c) having at least one fastening hole (734h).

[0180] The cap body (734a) may be placed on one side of the bearing body (732a) provided with an outer rim (732b) and an inner rim (732c). One side of the cap body (734a) may be in close contact with one side of the bearing body (732a). The other side of the cap body (734a) may face the roller bracket (24).

[0181] The cap shaft (734b) may correspond to a protrusion on one side of the cap body (734a). For example, the cap shaft (734b) may extend in a first direction from one side of the cap body (734a). The cap shaft (734b) may provide a rotation axis for the sub-roller (73). The cap shaft (734b) may be inserted into the hollow (732H) of the bearing body (732a).

[0182] A cap mount (734c) may be provided on the other side of the cap body (734a). The other side of the cap body (734a) may face one side of the cap body (734a). The cap mount (734c) may protrude from the other side of the cap body (734a). The cap mount (734c) may include at least one fastening hole (734h). The fastening hole (734h) may extend in the direction in which the cap shaft (734b) extends. For example, the cap mount (734c) may include two fastening holes (734h) extending in a first direction.

[0183]

[0184] Referring to FIGS. 47 and 48, a sub-roller (73) can be coupled to a roller bracket (24). A sub-fixing cap (734) of the sub-roller (73) can be coupled to a sub-roller mount (24d2) of the roller bracket (24). A sub-fastening member (fb) can be coupled to a fastening hole (734h) of the sub-fixing cap (734) by passing through a fastening hole (h, see FIG. 43) of the sub-roller mount (24d2). For example, a pair of screws (fb) can pass through the fastening holes (h, see FIG. 43) of the sub-roller mount (24d2) and be fastened to a fastening hole (734h) of the sub-fixing cap (734). Through this, the sub-fixing cap (734) can be fixed to the roller bracket (24), and the sub-roller body (73a) can rotate around the cap shaft (734b) of the sub-fixing cap (734).

[0185] The sub-fastening member (fb) can electrically connect the roller bracket (24) and the sub-roller (73). The sub-fastening member (fb) can electrically connect the roller bracket (24), the sub-roller (73), and the sunshade (45). That is, the sub-fastening member (fb) can function as an electrical passage.

[0186] The sub-fastening member (fb) may include a conductive material. The sub-fastening member (fb) may include metals such as steel alloys (e.g., stainless steel, tool steel, high-speed steel), non-ferrous alloys (e.g., copper alloy, aluminum alloy, titanium alloy), special alloys (e.g., nickel alloy, superalloy, Monel metal), and lightweight alloys (e.g., duralumin alloy, magnesium alloy).

[0187] When the sub-roller (73) is coupled to the roller bracket (24), the sub-fixing cap (734) can come into contact with the roller bracket (24). For example, the cap mount (734c) of the sub-fixing cap (734) can come into close contact with the sub-roller mount (24d2) of the roller bracket (24). Through this, the sub-roller (73) and the roller bracket (24) can be electrically connected in a contact manner.

[0188] The roller bracket (24) may include a conductive material. The roller bracket (24) may include a metal such as a steel alloy (e.g., stainless steel, tool steel, high-speed steel), a non-ferrous alloy (e.g., copper alloy, aluminum alloy, titanium alloy), a special alloy (e.g., nickel alloy, superalloy, Monel metal), or a lightweight alloy (e.g., duralumin alloy, magnesium alloy).

[0189] When the sub-roller (73) guides the direction of travel of the sunshade (45), sparks may occur between the sub-roller (73) and the sunshade (45) due to friction and contact. However, the sunshade (45), the sub-roller (73), and the roller bracket (24) are electrically connected to each other, so that sparks generated between the sunshade (45) and the sub-roller (73) can be transmitted to the roller bracket (24) through the conductive sub-roller (73).

[0190] Accordingly, the phenomenon of sparks generated between the light-blocking film (45) and the sub-roller (73) being transmitted to the display (10) can be reduced, and the damage caused by the sparks to the display (10) can also be reduced. In addition, the flickering phenomenon of the display (10) caused by the sparks can be improved.

[0191] The roller bracket (24) can be coupled to the base frame (25, see FIG. 45) through a bracket fastening member (fc). The roller bracket (24) can come into contact with the base frame (25, see FIG. 45). The roller bracket (24) can be electrically connected to the base frame (25, see FIG. 45). The bracket fastening member (fc) may contain the same material as the sub-fastening member (fb). Through this, the bracket fastening member (fc) can function as an electrical passage between the roller bracket (24) and the base frame (25, see FIG. 45).

[0192] The main roller (72) can be coupled to the roller bracket (24). The main roller (72) can be coupled to the main roller mount (24d1) of the roller bracket (24). The main fastening member (fa) can be coupled to the fixing cap (225) of the main roller (72) by passing through the fastening hole (h, see FIG. 43) of the main roller mount (24d1).

[0193] The main fastening member (fa) can electrically connect the roller bracket (24) and the main roller (72). The main fastening member (fa) can electrically connect the roller bracket (24), the main roller (72), and the sunshade (45). That is, the main fastening member (fa) can function as an electrical passage. The main fastening member (fa) may contain the same material as the sub-fastening member (fb).

[0194] The main roller (72) may be conductive. The main roller (72) may be electrically connected to the roller bracket (24).

[0195] Accordingly, the phenomenon of sparks generated between the light shield (45) and the main roller (72) being transmitted to the display (10) can be reduced, and the damage caused by the sparks to the display (10) can also be reduced. In addition, the flickering phenomenon of the display (10) caused by the sparks can be improved.

[0196]

[0197] Referring to FIG. 49, the display device (1) may include a middle frame (100), a rear frame (2a, 2b), a top roof (2c), a housing (90), and a bottom base (90B). The bottom base (90B) is located at the bottom of the display device (1) and may form the bottom of the display device (1). The housing (90) may be located on the bottom base (90B). The middle frame (100) may be coupled to or fixed to the bottom base (90B). The top roof (2c) may be coupled to or fixed to the top of the middle frame (100).

[0198] The first rear frame (2a) is positioned parallel to the middle frame (100) and can be coupled to the top roof (2c) and the housing (90). The second rear frame (2b) is positioned parallel to the middle frame (100) and can be coupled to the top roof (2c) and the housing (90).

[0199] The housing (90) may be a rectangular box that extends along the second long side (LS2, see FIG. 1) of the display (10). The housing (90) may include a top plate (91), a back plate (92), and side plates (93b).
