Why is there still a dim area in the center of slim light boxes?


      Slim light boxes are widely recognized as one of the most effective advertising mediums. Their high brightness and symmetrical illuminating can catch more customers' eyes, and make your brands more visible. But we usually see a dim area in the center of slim light boxes. The dim area is more noticeable when its size is larger. This not only does not have advertisement effect, and can damage the brand image and corporate image.

    How does this dim area happen?

     As we know, slim light boxes use the light guide panel (LGP) as illuminating. The LED strips light at the edges of slim light box. The light guide panel diffuses the light from the edge LED strip. But when the diffusing performance of light guide panel is low, there will be a dim area in the center. Usually, there are two LED strips on the two edges of slim light box. Sometimes, there are four LED strips on the four edges of slim light box. But the four LED strips still can not make up the low diffusing performance of light guide panel.

     The diffusing performance of light guide panel depends on the engraving technology. WilLite has the top advanced technology---LMDE(Laser Micro-Dot Engraving). LMDE light guide panel distributes light much more efficiently and evenly across the entire face of the panel, and has no dim area, no hotspots, no fluorescent tube banding, no dots and no lines.
