Embodiment Construction

[0022] Such as figure 1 and figure 2 As shown, the LED display device 100 in one embodiment includes a box body 10, a display module 30 accommodated in the box body 10, and a cooling assembly 50 for cooling the display module 30, and the cooling assembly 50 is interposed between the box body 10 and the display module. Between the groups 30, and wrapping the display module 30.

[0023] In order to ensure the heat dissipation and waterproof of the LED display device 100, as figure 1 As shown, the box body 10 includes a storage box 12 with an opening and a rear cover (not shown) that closes the storage box 12 .

[0024] Please also see image 3 and Figure 4 The storage box 12 includes a substantially rectangular and transparent display panel 121 , a box wall 123 extending upward along the edge of the display panel 121 , an air inlet duct 125 and an air outlet duct (not shown). In this embodiment, the air inlet duct 125 and the air outlet duct correspond to one end of the d...

Abstract

The invention discloses a light-emitting diode (LED) display device, which comprises a box body, a display module accommodated in the box body, and a cooling module used for cooling the display module, wherein the cooling module is arranged between the box body and the display module and wraps the display module; the box body comprises an air intake duct and an air outlet duct; and the air intakeduct and the air outlet duct both correspond to one end of the display module. The LED display device makes the air entering the box body flow in an enclosed environment formed by the box body and the cooling module through the combination of the box body and the cooling module, which greatly improves cooling efficiency.

Description

【Technical field】 [0001] The invention relates to a video playing device, in particular to an LED display device. 【Background technique】 [0002] Traditional LED (Light Emitting Diode, also known as light-emitting diode) display devices, such as high-brightness LED-backlit LCD TVs, basically use direct-lit LED-backlit liquid crystal modules. There are a lot of LED lamps used in this direct type LED backlight liquid crystal module, which results in a very high heat generation. [0003] However, in the traditional LED display device, in order to prevent water droplets from splashing into the LED display device, or even flowing into the interior, thereby damaging the electronic components, the display module is usually packaged in a closed casing, and a heat dissipation device is provided in the casing. The holes are used to dissipate the heat in the LED display device. [0004] However, the heat dissipation method of this LED display device only has a small amount of heat em...
