The difference between LED and VynEL™ is vast. The most common question is what's the brightness difference. While LED's put out more light, many times the pixelated approach to most LED technologies are unpleasant to product designers. As such, there's a need to diffuse most LED products and in doing so adds much bulk. VynEL™ is a similar thickness to paper, so adding this to objects barely affects the product, if at all.
