Problems solved by technology

Since the LED display adopts the above board box structure, its heat dissipation is improved, but it also limits the box frame to be composed of at least 12 mutually perpendicular brackets, which makes the box frame unable to achieve a more structural Requirements for simplicity, lower cost, and better thermal performance

Abstract

The invention discloses an LED display screen. The LED display screen is composed of a plurality of display screen units which are spliced by virtue of a display screen mounting frame; wherein the display screen unit comprises a display module, a display screen tank body, a heat sink and a connecting device; the display module is connected with the display screen tank body by virtue of the connecting device, and the display screen tank body is connected with the heat sink by virtue of the connecting device; the display screen tank body is a space frame structure composed of ten support elements which are mutually vertical, namely four transverse long support elements, two vertical long support elements and four short support elements, wherein the front of the display screen tank body is composed of two transverse long support element and two vertical long support elements, the four corners at the front of the display screen are respectively connected with two transverse long support elements by virtue of the short support elements; and all the support elements are fixed by virtue of connecting pieces, and the connecting pieces are connected with the support elements by virtue of fastening pieces. The invention has the advantages of good stability, good heat dissipation, lower cost, debugging convenience and simple structure.

Description

technical field [0001] The invention relates to the field of LED lighting devices, in particular to an LED display screen. Background technique [0002] At present, most of the LED display screens are made of a box structure. The LED display screen of the box structure is generally made of plates after bending and splicing. There are many manufacturing processes, high processing requirements, high labor intensity, and high manufacturing costs. The large display is composed of several independent LED display units, and the surface of each display unit is provided with a protective layer, which leads to poor ventilation and heat dissipation in the entire large display. In addition, the disassembly and assembly of the LED display with a box structure is extremely inconvenient: when several independent LED display units are assembled, a positioning pin is set in the center of the entire LED display body, and then assembled with this positioning pin as the center. When there is ...
