Electronic Displays With Silicone-Based Optical Bonding

Electronic displays are becoming increasingly important in daily life, from automobiles to smartphones and wearables to digital signage. As demand grows, display manufacturers require optically clear bonding materials to connect glass or plastic screens to various electronic modules. Strong, dependable adhesion is essential, as is support for a fantastic viewing experience. Furthermore, display manufacturers require solutions for high-volume assembly and a low total cost of ownership.

OCRs based on silicone is an excellent choice for bonding electronic display components. These innovative materials offer consistent adhesion to glass, plastic, or metal and high optical transmittance, low haze, and minimal yellowing for improved display readability and visibility. Silicone-based OCRs also support automated assembly and, with energy-efficient curing, can lower operational costs. Silicone-based OCRs can withstand harsh, application-specific environments and rigorous testing conditions.

For example, interior displays in the automotive industry must withstand high temperatures and humidity and prolonged sunlight exposure. As a result, test conditions include high-temperature degradation testing at 105°C, constant-humidity testing at 85°C with 85% RH, and thermal shock tests at temperatures ranging from 40 to 95°C. Display reliability is determined using accelerated weathering and light stability testing with proprietary equipment.

Although electronic displays were once only found in high-end vehicles, they are now found in a wide range of new cars and trucks.
