NuSil Technology has added two new optically clear silicone gels, LS1-3443 and Gel -8136, to its line of silicones for solid state lighting. The latest gels offer greater light output and optical clarity while also improving both impact- and heat-resistance, enabling LCD screen manufacturers to create next-generation displays for smart phones and stadium screens.
The optically clear silicone gels have a range of reflective index (RI) values from 1.38 to 1.54. With this choice of RI values, engineers can match the optical index of their screen's cover glass with the silicone gel that backs it to eliminate display washout in bright light without the need to increase LED output. The gels also provide soft and low modulus to absorb stress, reduce impact and improve ruggedness in newer, thinner displays.
LS1-3443 and Gel-8136 have been optimised for harsh environments, allowing manufacturers to increase light output while minimising power consumption and lowering the risk of product yellowing over time.
