For backlighting LCD panels, Osram Opto Semiconductors Inc. has introduced two white versions of the 1-W Oslon LX LEDs. Measuring 3 × 3 × 1.6 mm, they are side-injected into lightguides with a thickness of 2 to 4 mm, enabling the displays to be made with ultrathin profiles. Typical light output is 75 or 90 lm at 350 mA, enough to provide uniform backlighting for computer monitors and up to 65-in.-diagonal TVs. The integrated polynomial lens with a beam angle of 125° produces 80% injection efficiency into the lightguide. The multiwhite version covers 100% of the sRGB color space, with typical light output of 75 lm. The ultrawhite version covers 80%, with typical light output of 90 lm.
