Clear silicone gels for LCD screens.

NuSil Technology has added two new optically clear silicone gels, LSI-3443 and Gel 8136, to its full line of silicones for solid state lighting. The newest gels offer greater light output and optical clarity, while also improving both impact- and heat-resistance. This enables LCD screen manufacturers to create next-generation displays for smart phones and stadium screens, and everything in between, that are sharper, brighter and more rugged, according to NuSil

Manufacturers face a number of challenges when creating LCD displays that can be viewed in a wide range of light conditions, or when developing smaller, thinner screens to meet the need for wearable or more portable personal electronics. For example, bright sunlight makes screen viewing particularly difficult as it can create display washout, but increasing display brightness to address this problem drains battery power and generates unwanted heat. And as displays get thinner, there is a higher risk of breakage and lower device durability.

Optically Clear Silicone Gels address these challenges by offering a range of reflective index (RI) values from 1.38 to 1.54. With a 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.
