DF100L Uniformity Tape enables uniformity at an increased LED spacing of 20+mm, according to the company. A simple adhesive tape on one side with a micro-replicated optical pattern on the other side, the tape can be applied to the light injection edges of a Light Guide Plate. This micro-structured surface reduces dark zones and improves brightness uniformity by inducing lateral light spreading in the plane of the light guide near the light source.
