Abstract

The present invention relates to the technical field of display screens, and in particular to an LED box body, a manufacturing method of the LED box body, and an LED display screen. One side of the wall is the first side, and the first side is provided with main reinforcing ribs criss-crossing, and the main reinforcing ribs are provided with a plurality of first gaps at intervals along its length direction, and the main reinforcing ribs divide the space in the surrounding wall into multiple areas , there is an auxiliary reinforcing rib in the area, at least one end of the auxiliary reinforcing rib is connected with the main reinforcing rib whose length extends along the first direction, and a second notch is provided at the junction of the two, and the first notch and the second notch are both facing away from the body side. By setting the first notch, it is possible to avoid the large tightening force of the main rib during the die-casting cooling process, and by setting the second notch, the stress at the connection between the main rib and the auxiliary rib can be eliminated, thereby effectively avoiding the LED The box is deformed.

Description

technical field

[0001] The invention relates to the technical field of display screens, in particular to an LED box body, a method for manufacturing the LED box body, and an LED display screen. Background technique

[0002] The LED display is a flat panel display, which is spliced โ€‹โ€‹by small LED module panels. Each LED module panel includes an LED box and a display module. The display module is installed by magnetic attraction or screw fixing. on the LED box. With the improvement of LED display technology, the pixel pitch is getting smaller and smaller, and the requirements for the flatness of the front of the cabinet are getting higher and higher. The structure of the existing LED box is as follows figure 1 and 2 As shown, the box body includes a box body body 1' of a flat structure and a surrounding wall 2' annularly arranged on the front periphery of the box body body 1', and the front side of the box body body 1' is provided with several Regular criss-cross ribs 3', ...
