Description

Control box and display device having the same

[0001] The present disclosure relates to a control box and a display device comprising it.

[0002] As the information society develops, the demand for display devices is also increasing in various forms, and 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, LCD panels have a TFT substrate and a color substrate that face each other with a liquid crystal layer between them, and can display images using light provided by a backlight unit. Furthermore, OLED panels can display images by depositing an organic layer capable of self-luminescence on a substrate on which a transparent electrode is formed. In particular, display devices equipped with OLED panels have the advantage of being ultra-thin because they do not require a backlight unit.

[0004] The control box can be located separately 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 can be an AV box. The control box can exchange information with a display head equipped with a display panel that displays images, either wired or wirelessly.

[0005] Recently, much research has been conducted on the connectivity of these display devices.

[0092] Referring to FIGS. 20 and 21, a wheel (210) positioned on a base (203a) of a third plate (203) can rotate around a center pole (206). A hub cover (231) of a module bracket (230) can cover an upper portion of a hub (213, see FIG. 9) of the wheel (210). A spoke (214) of the wheel (210) can move under a spoke cover (232) of the module bracket (230).

[0093] A driving gear (251) located inside the gear housing (237) can engage with an inner gear (211G) of a driving rim (211) of a wheel (210). The driving gear (251) can transmit rotational power to the wheel (210). A duct (234) of the module bracket (230) can be aligned with an opening (203d) of the third plate (203).

The boss (B) can maintain a constant height from the third plate (203) to the rim supporter (233s).

[0095]

[0096] Referring to FIGS. 22 and 23, the lower surface of the driving rim (211) of the wheel (210) may be supported by or in contact with the outer rim (203b) of the third plate (203). The lower or lower surface of the hub (213) of the wheel (210) may be supported by or in contact with the inner rim (206b) of the center pole (206). The inner rim (206b) and the outer rim (203b) support the hub (213), which is the center of the wheel (210), and the driving rim (211), which is the outer portion, so that the wheel (210) can maintain horizontal balance while rotating. In addition, twisting and / or horizontal deformation of the wheel (210) can be suppressed.

[0097] If the horizontal balance of the wheel (210) is not maintained during rotation, vibration may occur as the wheel (210) rotates, and the antenna (ANT) fixed to the antenna mount (220) that rotates together with the driving rim (211) of the wheel (210) may be displaced up and down, which may lower the reception rate of the antenna (ANT).

[0098] The flange supporter (212) of the wheel (210) may include an inner rib (212d) and an outer rib (212c) that protrude from the driving rim (211) toward the rim supporter (233s). A guide groove (212b) may be located between the inner rib (212d) and the outer rib (212c). The inner rib (212d) may form an upper end of the driving rim (211) and / or the flange supporter (212). The outer rib (212c) may be adjacent to or parallel to the inner rib (212d). The guide groove (212b) may be located between the inner rib (212d) and the outer rib (212c). The height of the inner rib (212d) from the guide groove (212b) may be greater than the height of the outer rib (212c) from the guide groove (212b). The side and lower surfaces of the outer rib (212c) may be exposed from the outside of the driving rim (211). The rotation indicator (207) may be fixed to the lower surface of the outer rib (212c).

[0099] The vertical part (233a) of the rim supporter (233s) can be inserted into the guide groove (212b). The horizontal part (233c) of the rim supporter (233s) can face the inner rib (212d) of the flange supporter (212). The outer part (233b) of the rim supporter (233s) can face the outer rib (212c) of the flange supporter (212). The horizontal part (233c) of the rim supporter (233s) can be spaced apart from the inner rib (212d) of the flange supporter (212). The vertical part (233a) of the rim supporter (233s) can be supported by or in contact with the guide groove (212b) of the flange supporter (212). The driving rim (211) of the wheel (210) can move between the rim supporter (233s) and the outer rim (203b) of the third plate (203). In the radial direction of the outer rim (203b) of the third plate (203), the guide groove (212b) can be located outside the outer rim (203b) by a certain distance (D). The point where the vertical part (233a) of the rim supporter (233s) contacts the guide groove (212b) of the flange supporter (212) may not be aligned with the point where the driving rim (211) contacts the outer rim (203b) of the third plate (203), but may be located outside the outer rim (203b) in the radial direction of the outer rim (203b) of the third plate (203). It is possible to prevent deformation of the driving rim (211) and / or the flange supporter (212) of the wheel (210) in the up-down direction and / or left-right direction.

[0100] Accordingly, the driving rim (211) of the wheel (210) maintains horizontal balance while rotating, and the rim supporter (233s) positioned opposite the antenna (ANT) with respect to the center pole (206) restrains the shaking of the flange supporter (212) and / or the driving rim (211), so that the antenna (ANT) can rotate stably. Even if the antenna (ANT) rotates, the reception rate and / or reception sensitivity of the antenna (ANT) can be maintained.
