Flexible transparent LED display screen capable of being crimped at will

Abstract

The invention discloses a flexible transparent LED display screen capable of being crimped at will, belonging to the field of LED display screens. The flexible transparent LED display screen comprisesa modified PET film layer, wherein a copper-plated circuit layer is arranged on one side of the modified PET film layer, a low-temperature solder paste layer is arranged on the outer side of the copper-plated circuit layer, an SMT patch is arranged on the outer side of the low-temperature solder paste layer, LED lamp beads are fixedly connected to the outer side of the SMT patch, and one side ofthe modified PET film layer is coated with a protective layer. According to the invention, the modified PET film layer is adopted, and the modified PET film layer is a flexible transparent thin film,so the display screen of the invention can be crimped at will; a macromolecular anti-precipitation layer and a pressure-sensitive adhesive layer are arranged on the modified PET film layer; the modified PET film layer is allowed to resist a high temperature of 180 DEG C through the arrangement of the pressure-sensitive adhesive layer, and reflow soldering of the low-temperature solder paste layeris facilitated; the macromolecular anti-precipitation layer can prevent the modified PET film layer from precipitation, fogging and the like at high temperature, the LED lamp beads can be protected against pollution, and meanwhile, the softness of the modified PET film layer is not affected.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a flexible and transparent LED display screen with arbitrary curls. Background technique [0002] Traditional large-scale display screens have strict requirements on installation conditions, because there may be non-planar installation surfaces in both outdoor and indoor environments. In this case, the installation location needs to be changed, or It is necessary to design a special mounting bracket to meet the installation requirements. However, these two methods will bring additional costs such as manpower and materials, and the mounting bracket will also increase the overall weight of the display screen. In view of the fact that it is difficult to achieve seamless splicing of LCD displays, and it is difficult to build a flexible structure, flexible LED displays have emerged as the times require. The existing flexible LED displays are mainly arranged in sequence by vertical L...

[0002] Traditional large-scale display screens have strict requirements on installation conditions, because there may be non-planar installation surfaces in both outdoor and indoor environments. In this case, the installation location needs to be changed, or It is necessary to design a special mounting bracket to meet the installation requirements. However, these two methods will bring additional costs such as manpower and materials, and the mounting bracket will also increase the overall weight of the display.

In view of the fact that it is difficult to achieve seamless splicing of LCD displays, and it is difficult to build a flexible structure, flexible LED displays have emerged as the times require. The existing flexible LED displays are mainly arranged in sequence by vertical LED light strips and using cables However, the existing flexible LED display is fixed on a hard substrate and cannot be curled arbitrarily according to needs, and it is not equipped with an antistatic mechanism, which is greatly affected by static electricity and has a certain limitations of use
