Description

CROSS-REFERENCE TO RELATED APPLICATIONS Pursuant to 35 U.S. C. § 119(a), this application claims the benefit of earlier filing date and right of priority to Korean Patent Application No. 10-2024-0155292, filed on Nov. 5, 2024, the contents of which are all hereby incorporated by reference herein in their entireties. TECHNICAL FIELD This disclosure relates to a display device. BACKGROUND As the information society develops, the demand for display devices is also increasing in various forms. In response to this, various display devices such as Liquid Crystal Display Device (LCD), Organic Light Emitting Diodes (OLED), and Micro LED have been researched and used in recent years. Among these, the LCD panel has a TFT substrate and a color substrate that are opposite to each other with a liquid crystal layer interposed therebetween, and may display images by using light provided from a backlight unit. In addition, an OLED panel may display images by depositing an organic layer that can emit light naturally on a substrate on which a transparent electrode is formed. In particular, a display device equipped with 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. A control box can be used separately from the display device, while being adjacent to a 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 with a display head equipped with a display panel that displays an image, by wire/wireless. Recently, much research has been conducted on the connectivity of such a display device.

The disclosure may further provide a display device capable of improving the reception rate of an antenna of a communication module. The disclosure may further provide a display device capable of improving the radiation performance of an antenna of a communication module. The disclosure may further provide a radome and an air room structure inside the radome for improving the radiation performance of an antenna that may be interfered with by electronic components surrounding an antenna of a communication module. The disclosure may further provide a structure capable of effectively dissipating heat from a communication module. The disclosure may further provide a display device capable of improving the assembly durability of an antenna. In accordance with an aspect of the present disclosure, a display device includes: a display panel having a plane for displaying an image; a frame which is positioned at a rear of the display panel, and to which the display panel is coupled; and a communication module which is positioned at one side of the frame, and protrudes outward from the one side of the frame, in which the communication module includes: a housing providing an internal space; and an antenna unit which is positioned in the internal space of the housing, has a bottom surface intersecting with the plane of the display panel, and has a side surface that forms an edge of the bottom surface and faces a front of the display panel, in which the antenna unit includes: a plurality of first antennas arranged on the bottom surface of the antenna unit; and a plurality of second antennas arranged on the side surface of the antenna unit, in which the housing includes: a lower rib forming a first air room by supporting the bottom surface of the antenna unit in the housing facing the bottom surface of the antenna unit; and a spacer which supports the side surface of the antenna unit and forms a second air room between the housing and the side surface of the antenna unit.
