Description

Control box and display device equipped with the same

[0001] The present disclosure relates to a control box and a display device equipped with the same.

[0002] As the information society develops, the demand for display devices is increasing in various forms; in response to this, various display devices such as LCD (Liquid Crystal Display Device), OLED (Organic Light Emitting Diodes), and Micro LED are being researched and used in recent years.

[0003] Among these, an LCD panel is equipped with a TFT substrate and a color substrate facing each other with a liquid crystal layer in between, and can display an image using light provided from a backlight unit. Additionally, an OLED panel can display an image by depositing a self-emissive organic layer on a substrate having a transparent electrode formed thereon. In particular, a display device equipped with an OLED panel has the advantage of being able to be implemented as an ultra-thin form factor because it does not require a backlight unit.

[0004] The control box can be spaced apart from the display device and used adjacent to the user. The control box can provide various information to the display device. For example, the control box may be an AV box. The control box can exchange information wirelessly or via wired connection with a display head equipped with a display panel that displays images.

[0005] Recently, much research has been conducted on the connectivity between such control boxes and display devices.

[0006] The present disclosure aims to solve the aforementioned problems and other problems.

[0007] Another purpose may be to provide a display device that communicates wirelessly with a control box.

[0008] Another purpose may be to provide a rotation mechanism for the communication module equipped in the control box.

[0009] Another purpose may be for the communication module to provide a waterproof structure for the rotatable control box.

[0010] According to one aspect of the present disclosure for achieving the above-described purpose, a control box may comprise: a case having an opening with one side open; a rotating plate covering the opening of the case and rotating within the opening of the case; an antenna module coupled to the rotating plate inside the case; and a bracket coupled to the rotating plate inside the case, with a portion overlapping with the case.

[0011] The display device may include: a display panel; a frame to which the display panel is coupled; and a communication module coupled to the frame and wirelessly communicating with an antenna module of the control box.

[0012] The effects of the control box and the display device equipped with the same according to the present disclosure are described as follows.

[0072]

[0073] Referring to FIG. 12 together with FIG. 11, the top supporter (232) of the outer top (230) may include a support rim (232a) and a guide rim (232b). The support rim (232a) may form a lower step from the top cover (231) of the outer top (230). The support rim (232a) may include an upper contact part (232c) and a lower contact part (232d). The upper contact part (232c) may be formed protruding from the upper surface of the support rim (232a). The lower contact part (232d) may be formed protruding from the lower surface of the support rim (232a). The upper contact part (232c) may be referred to as an upper supporter (232c) or an upper dam (232c). The lower contact part (232d) may be called a lower supporter (232d) or a lower dam (232d).

[0074] The upper contact part (232c) of the support rim (232a) can support the ring plate (252) of the inner top (250). The upper contact part (232c) can contact a contact sheet (254) fixed to the ring plate (252). The upper surface of the upper contact part (232c) of the support rim (232a) can form a curve. The upper contact part (232c) of the support rim (232a) can make point contact or line contact with the contact sheet (254) of the ring plate (252) of the inner top (250).

[0075] The lower contact part (232d) of the support rim (232a) can support the step part (263) of the bracket (260). The lower contact part (232d) can contact the contact sheet (267) fixed to the step part (263) of the bracket (260). The lower contact part (232d) of the support rim (232a) can form a curve on its lower surface. The lower contact part (232d) of the support rim (232a) can make point contact or line contact with the contact sheet (267) of the step part (263) of the bracket (260).

[0076] Accordingly, the inner top (250) and bracket (260) can rotate with respect to the top supporter (232) of the outer top (230) to minimize friction.

[0077] A guide rim (232b) may be formed on the inner surface of a support rim (232a). The thickness of the guide rim (232b) may be greater than the thickness of the support rim (232a).

A contact sheet (254) may be positioned between the inclined surface (232bb) of the guide rim (232b) and the inclined surface (253a) of the circle wall (253). The inclined surface (253a) of the circle wall (253) may form an acute angle with respect to the vertical surface (253b) of the circle wall (253).

[0078] Accordingly, the position of the inner top (250) can be aligned. When the inner top (250) rotates from the outer top (230), the center of rotation of the inner top (250) can be aligned with the center of rotation of the outer top (250).

[0079] Moisture may flow between the ring plate (252) of the inner top (250) and the top cover (231) of the outer top (230). The upper contact part (232c) can prevent the incoming moisture from flowing into the bracket (260). If the amount of incoming moisture is large enough to exceed the upper contact part (232c), moisture may accumulate in the horizontal part (261) of the bracket (260). The moisture can be stored without overflowing to the outside of the bracket (260) by the dam barriers (264a, 264b, see FIG. 8) and the step part (263) formed at both ends of the horizontal part (261) of the bracket (260). The moisture accumulated in the bracket (260) can naturally evaporate over time.
