Full color LCDs are the most important interface for the mobile phone user. Today, the trend is moving towards thinner devices with clearer pictures, which support the new multimedia and video applications to be launched soon. Understanding LCD requirements and trends enables OSRAM Opto Semiconductors to provide new LED solutions for better displays. A wide variety of thin, sidelooking LEDs ensure the perfect fit for your application and give more design-in flexibility due to the availability of LEDs with different heights: 1 mm, 0.8 mm, 0.6 mm, 0.5 mm.

OSRAM Opto Semiconductors chip technology provides ultra low forward voltage (Uf) and high efficiency resulting directly in power saving and longer stand-by times. The reflector LEDs are encapsulated in silicone in order to guarantee the long lifetimes essential for the new TV, game and multimedia applications. Our detailed knowledge of the whole range of mobile phone applications enables us to optimize our LEDs for coupling into lightguides. OSRAM Opto Semiconductors takes application analysis into account in its new developments - to benefit its customers.
