The graphic used in our SEG fabric light box is Silicone Edge Graphic (SEG), which is a tension blackout fabric surrounded by a thin silicone strip inserted into a narrow slot along the inner edge of the light box frame. Our SEG backlit fabric light boxes are designed for indoor use and are ideal for large backlit displays, which can be used in retail stores, corporate offices, health and medical facilities, exhibitions and trade shows, as well as art galleries and museums for maximum visual effects.
