LED screen with light guide mask and manufacturing method of LED screen

Abstract

The invention discloses an LED screen with a light guide mask and a manufacturing method of the LED screen. The LED screen comprises a PCB substrate, LED lamp beads, the light guide mask and positioning screws. By means of the technical scheme, the waterproof performance, the damp-proof performance, the external impact resistance and the high abrasion resistance of the LED screen can be improved,meanwhile, visual splicing seams and light transmitting conditions can be effectively eliminated, and the use sense of the LED screen is improved. Besides, the light guide mask adopted in the technical scheme can further improve the fusion degree of the LED screen and the surrounding environment, the use scene of the LED screen is expanded, and the damage rate of repeated disassembly and assemblyof the LED screen is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an LED screen with a light guide mask and a manufacturing method thereof. Background technique [0002] With the continuous development of LED display related technologies, more and more new LED screens are used in all aspects of daily life: for example, in the outdoor ground imaging display environment, it is necessary to allow users to Free walking or movement; or in desktop imaging display environments such as bars, desks, etc., it is necessary to allow users to place other items or write on the LED screen with a light guide mask, which brings great demands on the technology of LED screens. challenge. [0003] At present, in order to meet the performance requirements of waterproof, anti-collision, and enhanced wear resistance, the LED display screens used in the above environments are mainly produced by the following two processes: [0004] One is to fill the sid...

AI Technical Summary

Problems solved by technology

[0006] For the LED display screen using the glue filling process, although it plays a waterproof role, it has the following technical defects: when it is impacted by an external force, because the PCB board bears the force, and the PCB board is generally composed of multi-layer materials, the thickness Within 2mm, there is no high load-bearing strength, so it is very easy to damage; at the same time, due to the low hardness of the glue filling surface, the wear resistance is poor, and the display effect will be significantly reduced due to wear after long-term use

[0007] As for the technology of using covered transparent materials to increase wear resistance and external shock resistance, there are also corresponding technical defects: due to the inability to produce super-sized covered transparent materials, most of the existing LED displays covered with transparent materials are It is spliced ​​by multiple pieces of covered transparent materials - and because the transparent materials have a certain thickness, the light of the LED lamp beads is easy to highlight the splicing seams of the covered materials under the action of refraction, thereby reducing the display effect; in addition, due to The surface of the transparent material of the cover is a mirror surface, and the light will reflect when it propagates between different media, which will further reduce the display effect presented by the LED display
