Description

Technical Field

[0001] This utility model relates to the field of crystal film screen technology, specifically a packaging structure for a flexible crystal film screen. Background Technology

[0002] Crystal film screens are currently the most commonly used type of indoor display screen, primarily used in glass curtain walls or areas with curved or irregular three-dimensional surfaces. Crystal film screens utilize bare LED chips and embedded LED beads technology. The light panel uses a transparent crystal film film with a transparent mesh circuit etched on the surface. After the components are attached, a vacuum sealing process is used. The product's main advantages are its lightweight, thinness, flexibility, and ability to be cut to size. It can be directly attached to glass curtain walls without damaging the original building structure. When not in use, the screen is invisible, does not affect indoor lighting, and is undetectable from a distance. Crystal film screens have a light transmittance of up to 95%, producing vivid and bright images that make product images more eye-catching, and providing users with an excellent visual experience through superior color reproduction.

[0003] A utility model patent with Chinese patent publication number CN219457094U discloses an LED crystal film screen. After studying the prior art and the above-mentioned patent, it was found that the LED crystal film screens on the market have poor anti-scratch effect on their surface. When they are rubbed against external objects, their surface is prone to scratches, which affects their use later. Therefore, this utility model proposes a flexible crystal film screen packaging structure. Utility Model Content
