Detailed Description

A light-emitting diode (LED) display screen is generally composed of a plurality of LED display units as a display device for displaying various information such as text, graphics, and video. A plurality of LED display elements splice each other, can form the LED display screen that has different size and shape to satisfy with under the different scenes and different user's demand.

As described in the background section, conventional LED display units include a LED display panel, a bottom case, and a cabinet. The LED display lamp panel is fixed on the bottom case firstly, and is fixed on the box body through the bottom case, so that the LED display lamp panel in the LED display unit is fixed on the box body, power supply and control are conducted on the LED display lamp panel through a power supply card and a receiving card in the box body, the display function of the LED display unit is achieved, meanwhile, due to the arrangement of the box body, the control structure in the box body can be prevented from being exposed, such as the power supply card and the receiving card, the safety performance and the protection performance of the LED display unit are met, and meanwhile, the requirement of Electromagnetic Compatibility (EMC) of the LED display unit can be met.

However, due to the existence of the bottom shell and the box body in the LED display unit, the traditional LED display unit formed after assembly is thick and heavy, the light and thin design of the LED display screen is difficult to meet, when the plurality of LED display units are adsorbed on the square tubes of the LED display unit to achieve wall-mounted installation of the LED display screen, the thickness of the LED display screen after installation often exceeds 100mm, the LED display screen occupies a large installation space, and ultra-thin wall-mounted installation of the LED display screen becomes difficult.

The thickness of the mounted LED display panel includes the thickness of a square tube (tube thickness) and the thickness of the LED display unit itself, and the square tube can be a partial structure of the LED display panel, and therefore the thickness of the mounted LED display panel can be understood as the thickness of the LED display panel. Taking a square tube with a thickness of 20mm commonly used in an LED display screen as an example, the thickness of an LED display unit itself often exceeds 80mm.

With the popularization of LED display screens, users have certain requirements for thinning the thickness of the mounted LED display screen in application places such as meeting rooms and classrooms. Therefore, under the condition that the thickness of the square tube is not changed, the thickness of the LED display screen is reduced by reducing the thickness of the LED display unit, and the technical problem to be solved is solved.

In view of this, the present invention provides a display device, which includes one or at least two (e.g., three or four, etc.) display units. The utility model discloses a display element's setting can reduce display element and display device's the thickness of week side edge by a wide margin, helps reducing display device's thickness, realizes that display device's ultra-thin wall installation that pastes to satisfy under application places such as meeting room, classroom, the demand of user to the frivolous of display device's thickness.

When the display device comprises at least two display units, the display device further comprises a metal fixing piece, the at least two display units are spliced with each other, and the metal fixing piece is connected to the splicing position of the two adjacent display units so as to support and fix the display units at the splicing position of the display device through the metal fixing piece.

The end of the metal fixing member may extend along the joint of two adjacent display units, and the cross-sectional shape of the metal fixing member in a direction perpendicular to the extending direction of the metal fixing member may include, but is not limited to, a hollow rectangle, such as a square. In this case, the metal fixture may be also called a square tube. Thus, the display unit is supported by the metal fixing member, and the weight of the display device can be reduced, which contributes to the development of the display device toward the thinning direction.

The utility model discloses a display element passes through bracket assembly's setting, with drain pan and box in replacing traditional LED display element, it is fixed to show the lamp plate in the display element to realize in the realization, when satisfying display element's electromagnetic compatibility and security performance, can make the reduction that all side edge's thickness and weight of display element are showing, help realizing display element and display device's frivolousness, with the thickness that reduces display device, realize display device's ultra-thinness and paste the wall installation, in order to satisfy in meeting room, under the application places such as classroom, the user is to the frivolous demand of display device's thickness.

The structure of the present invention will be further explained with reference to the drawings and the embodiments.

Therefore, the thickness of the peripheral edge of the display unit 100 of the present invention is reduced by a larger margin than the thickness of the conventional LED display unit itself, which helps to realize the light and thin display device and the ultra-thin wall-mounted display device.

To further reduce the thickness of the display device, the control cavity 323 may be further disposed in the middle of the cover plate 30, so that when the display device is supported at the joint by the metal fixing member, the metal fixing member may be located at the side of the control cavity 323, thereby further reducing the thickness of the display device.
