The ultra-thin, flexible Flex 15 LED display is an improved and innovative design based on a conventional transparent LED screen that eliminates the rigid light bar or PCB, making the screen body thinner, more transparent, flexible, and bendable. The transparent film screen utilizes a technology that embeds crystal beads made from LED lamp beads; the lamp board incorporates a transparent film, the surface is etched with a transparent grid circuit, and the components are bonded to the surface after a vacuum sealing process. It can be mounted directly onto a glass curtain wall without damaging the building’s original structure; When not in use, the screen is invisible, does not affect interior lighting, and, when viewed from a distance, no traces of the screen’s installation are visible. The light transmittance of this thin, flexible LED display is as high as 94%, which ensures a bright image, making the product more eye-catching, while the superb color reproduction creates an excellent visual experience for users. LED displays with transparent Flex 15 film are widely used in glass curtain walls, advertisements in shopping malls, at exhibitions, and in other settings such as creative artistic landscapes and similar environments.
