Abstract

The invention provides an LED (Light-emitting Diode) display device which comprises an LED display board (1), and a mask arranged on one side of the LED display board (1), wherein the mask comprises a plurality of light-transmission cover units (10); the light-transmission cover units (10) are bonded with the LED display board (1); and a locating structure is arranged among the light-transmission cover units (10) and the LED display board (1) and used for limiting pasting positions of the light-transmission cover units (10) on the LED display board (1). The LED display device is small in splicing gap, and better in display effect.

Description

technical field [0001] The present invention relates to the technical field of LED display, in particular to an LED display device. Background technique [0002] In the prior art, the LED display screen is composed of individual LED lights. The above-mentioned LED display screen will appear grainy when displayed, and moiré will appear due to the grainy phenomenon when taking pictures. In the prior art, the above problem is solved by adding a piece of translucent glass or translucent plastic plate outside the LED display screen, but the above method has the following defects: [0003] 1. Considering transportation and other reasons, the size of the glass or plastic plate is limited, which leads to the fact that the display screen cannot be enlarged infinitely and can only be limited to a certain size. If it exceeds a certain size and needs to be spliced, since the glass or plastic plates need to be fixed by a frame after splicing, that is, each glass or plastic plate has a ...
