today introduced the industry's thinnest top-firing tricolour surface-mount LED (light-emitting diode), intended primarily for backlighting and status indicators in ultra-thin, feature-rich mobile phones and PDAs.

The new top-firing LED, in addition to Agilent's recently announced side-firing LEDs, permits handset and PDA designers to mix separate red, green and blue light sources in any combination.

In handsets and other handheld devices, separate colours can indicate incoming SMS (short messaging system) messages, e-mail and stock news. They can even identify different callers. The availability of an unlimited range of illumination colours also provides a new degree of design flexibility in many other applications, such as backlighting and status indication in office and industrial equipment and home appliances.

"Our new 0.35 mm-thick, top-firing tricolour LED is the first of its kind to include a red, green and blue die in such a small package," said Cheng Kai Chong, worldwide marketing manager for the Optoelectronic Products Division in Agilent's Semiconductor Products Group. "Our latest device is enabling the next generation of ultra-thin portable products with multiple backlighting colour options."
