Patent Description:
With the advent of the information society, various demands for display devices are increasing. Various display devices, such as liquid crystal display (LCD) devices, plasma display panel (PDP) devices, electroluminescent display (ELD) devices, vacuum fluorescent display (VFD) devices, and organic light-emitting diode (OLED) devices, have been recently studied and used in response to various demands for display devices.

Thereamong, a display device using an organic light-emitting diode (OLED) is advantageous in that it has better luminance characteristics and viewing angle characteristics than a liquid crystal display device, and has an ultra-thin profile because it does not require a backlight unit, unlike the liquid crystal display device. A control box may be positioned so as to be spaced apart from a display device and adjacent to a user so as to be used by the user. The control box may provide various pieces of information to the display device. For example, the control box may be an AV box. The control box may exchange information with a display head, which is provided with a display panel displaying an image, in a wired/wireless manner. Recently, various studies have been conducted on the connectivity of such a display device.

<CIT> and <CIT> disclose rotating antenna included inside a control box.

It is another object of the present disclosure to provide a control box configured to be wirelessly connected to a head provided with a display panel.

It is still another object of the present disclosure to provide a stacked structure of components of a control box.

It is still another object of the present disclosure to provide a mechanism capable of improving the reception rate of an antenna of a wireless control box.

The housing <NUM> may have an open area defining the outlet <NUM> of the fan <NUM>.

The heat generated in the region under the third plate <NUM> may flow to the outlet <NUM> of the housing <NUM> via the opening 230V in the third plate <NUM>, the flow passage 241V in the shock absorber <NUM>, and the inlet <NUM> of the housing <NUM>. The upper surface of the housing <NUM> may be spaced apart from the upper plate <NUM> of the rotary plate <NUM>. A gap G may be formed between the upper surface of the housing <NUM> and the upper plate <NUM> of the rotary plate <NUM>. An airflow path may be created between the upper surface of the housing <NUM> and the upper plate <NUM> of the rotary plate <NUM> due to the pressure difference generated by the strong discharge of air through the outlet <NUM> of the fan <NUM>.

A discharge guide <NUM> may be disposed on the outer periphery of the outlet <NUM> of the fan <NUM>.

Accordingly, it may be possible to prevent the air discharged from the outlet <NUM> of the fan <NUM> from flowing reversely.

Referring to <FIG> and <FIG>, as described above, the case <NUM> may further have the third introduction hole <NUM> formed therein. The third introduction hole <NUM> may be formed in the lower surface of the case <NUM>. External air introduced into the case <NUM> through the first introduction hole <NUM>, the second introduction hole <NUM>, and/or the third introduction hole <NUM> may absorb heat generated from the power supply PSU and/or the main board MB, and may be forcibly discharged to the outside of the case <NUM> through the discharge hole <NUM> by the fan <NUM>.

External air introduced into the case <NUM> through the first introduction hole <NUM>, the second introduction hole <NUM>, and/or the third introduction hole <NUM> may be passed through the heat sink <NUM> (refer to <FIG>) by the cooling fan <NUM> of the transceiver <NUM>, and may be forcibly discharged to the outside of the case <NUM> through the discharge hole <NUM> by the fan <NUM>.

The main board MB or the transceiver <NUM> may be a heat source, the temperature of which is higher than that of the power supply PSU. Therefore, the heat generated from the main board MB may be removed in a forcible air-cooling manner by the fan <NUM>, and the heat generated from the transceiver <NUM> may be removed in a forcible air-cooling manner by the cooling fan <NUM>.
