Description

Control box and display device having the same

The present disclosure relates to a control box and a display device having the same.

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 recently.

Among these, the LCD panel has 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. In addition, the OLED panel can display an image by depositing an organic layer that can emit light on its own on a substrate on which a transparent electrode is formed. In particular, a display device having an OLED panel has the advantage of being able to be implemented in an ultra-thin form because it does not require a backlight unit.

In addition, the antenna units (251, 252) can pivot together with the dial (205). Accordingly, the antenna units (251, 252) can rotate left and right and pivot up and down. For example, the antenna units (251, 252) can rotate left and right within a range of 180 degrees and pivot up and down within a range of 50 to 90 degrees. Meanwhile, the communication module (250) can be located between the rotation axis (Ax) of the turntable (203) and the outer circumference of the turntable (203).

Referring to FIG. 21, the fan (240) may include a housing (242), an inlet (243, inlet), and an outlet (244, outlet). For example, the fan (240) may be a sirocco fan. The buffer member (241) may be disposed between the third plate (230) and the housing (242). The buffer member (241) may have a hole (241V) corresponding to the inlet (243), and the third plate (230) may have an opening (230V) corresponding to the hole (241V).

When the fan (240) is operated, air can pass through the opening (230V) of the third plate (230), the hole (241V) of the buffer member (241), the inlet (243), and the outlet (244). Accordingly, the fan (240) can remove heat generated under the third plate (230).

Referring to FIGS. 22 and 23, a power supply unit (PSU) may be mounted on the first plate (210) between the first plate (210) and the second plate (220). The power supply unit (PSU) may be positioned closer to the first plate (210) than to the second plate (220). Accordingly, heat generated in the power supply unit (PSU) may be transferred to the first plate (210) and removed by air passing between the power supply unit (PSU) and the second plate (220).

The main board (MB) can be mounted on the second plate (220) between the second plate (220) and the third plate (230). The main board (MB) can be positioned closer to the second plate (220) than to the third plate (230). Heat generated from the main board (MB) can be more than heat generated from the power supply unit (PSU). When the fan (240) is operated, air that is introduced from the outside of the case (201) into the inside of the case (201) through the first inlet (202), the second inlet (204, see FIG. 6), and/or the third inlet (208) can exhaust heat generated from the power supply unit (PSU) and/or the main board (MB) to the outside through the fan (240) and the exhaust port (206). Additionally, air can pass through the heat sink (253) by the cooling fan (257) and be discharged to the outside through the fan (240) and the exhaust port (206).
