Abstract

The present invention relates to a display module, comprising: a bottom case; a lamp board fixedly connected with the bottom case; a plurality of LED lamp beads arranged on the lamp board; a waterproof ring including a first ring segment and a second ring segment, the plane where the first ring segment is located has an included angle with the plane where the second ring segment is located, and the first ring segment of the waterproof ring is pressed tightly when the lamp board is fixed to the bottom case fixed between the lamp board and the bottom shell, the second ring segment is arranged around the periphery of the lamp board; and a mask, the mask is provided with a number of lamp holes corresponding to the LED lamp beads, the lamp holes and The LED lamp beads are closely fitted and fixed, and the peripheral edge of the mask is fixedly connected to the end of the second ring segment away from the first ring segment. The above display module has a good waterproof effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module. Background technique [0002] There are two ways to waterproof the outdoor LED display. One is to add a glass window-like waterproof cover outside the display to protect the display on the basis of the indoor structure of the display. The second is to carry out sealed and independent waterproof design of the module, put the lamp board inside the bottom shell, then fill the lamp surface with glue to seal, and then fix the mask on the bottom shell with screws. The window-type display screen needs to add a layer of glass to protect the display screen, which affects the display effect and takes up a lot of space. The method of independent waterproofing of modules has great limitations at present. It is only suitable for display modules with large dot spacing. Because the gap between LED lamp beads is too small for small dot spacing, it is impossible to set the scr...
