The semitransparent sheet with high conduct and formability.  Conductive coating processed on polyvinyl chloride/PS/PET material. Dramatically reduce the number of LEDs and the cost while keeping the same illumination effect. Low power consumption Low-profile design (Typically, 0.2mm. 0.1mm thickness is under development) Consistent brightness Design flexibility (e.g. integration with keypads) * Shin-Etsu is also able to design light simulation for your particular application

Structure:

In order to minimize the loss on tactility, without sacrificing the illumination, light guide is usually glued onto the corners of the dome sheet.

Side-fire LED (with silicone light guide):

Features Side-fire LED and selected lightened areas through silicone light guide technology Weakness Transparency, Feeling

Optical Analysis:

Surface brightness analysis using actual prototype

Advantages:

Brighter and more efficient light distribution Shin-Etsu Silicone light guide Other company's light guide
