Abstract

The invention discloses an LED box body, an LED display screen and an assembling method thereof. The LED box body comprises an installing face, a back face and multiple side faces, wherein the installing face and the back face are opposite to each other and are respectively used for fixing LED modules and a supporting frame, the side faces are in adjacent connection with the installing face and the back face, and the faces jointly define the housing of the LED box body. the multiple side faces include a first group of side faces and a second group of side faces, the first group of side faces and the second group of side faces respectively comprise first side faces and second side faces which are adjacent to each other, the first group of side faces comprises steps, and the steps comprise side faces extending from the installing face to the back face and bottom faces extending from the bottom ends of the side walls. The LED box body utilizes the steps on the side faces to block gaps among the LED modules, and accordingly standardized assembly of the LED display screen is achieved, and the reliability and durability of the LED display screen in a severe environment are improved.

Description

technical field [0001] The present invention relates to LED display technology, more specifically, to an LED box used for an LED display, an LED display and an assembly method thereof. Background technique [0002] Light-emitting diode (LED) displays have the following advantages: high grayscale, wide viewing angles, rich colors, and customizable screen shapes. Therefore, LED display screens are widely used in various fields such as industry, transportation, commercial advertisements, information release, and sports competitions. [0003] The pixel elements used in LED displays are LEDs. In order to obtain a large display area and resolution, the LED screen usually consists of multiple LED cabinets spliced ​​together. Multiple LED modules are installed on the LED box. Each LED module includes an array of multiple LEDs mounted on a printed circuit board and a driving circuit. In the LED display, the LED box not only provides a mechanical support surface for the LED module...
