1-W LEDs Enable Manufacture Of Ultra-Thin LCDs

OSLON LX 1 W LEDs are used for backlighting LCD panels with plenty of light from an extremely small emitter. Measuring just 3 mm x 3 mm x 1.6 mm, the two white versions of the new LEDs are perfect for side injection into light guides with a thickness of 2 to 4 mm so the displays can be made with ultra thin profiles. This enables the manufacture of ultra-thin and uniform displays with LEDs mounted along one edge only. The compact LED format and the high light output of typically 75 lm or 90 lm at 350 mA is sufficient to inject the light from two edges or even from only one side to provide uniform backlighting for computer monitors and TVs up to 65-in. diagonal in size. The integrated polynomial lens with a beam angle of 125° is designed to achieve an injection efficiency into the light guide of almost 80%. The OSLON LX is available for two color spaces. The multi-white version covers 100% of the sRGB color space and has a typical light output of 75 lm, while the ultra-white version of the LED covers 80% of the sRGB color space and is a little brighter, with a typical light output of 90 lm. OSLON LX is manufactured using the latest ThinGaN chip technology with chip level conversion and provides high optical efficiency and uniform distribution of light. The substrate and lens materials are optimized for long lifetimes, exceeding those of CCFL (cold cathode fluorescent lamp). OSRAM OPTO SEMICONDUCTORS, Sunnyvale, CA. (866) 993-5211.
