Plessey announced today that its dotLED range, designed specifically for wearable applications, has been expanded with a wider selection of colours, including red, green and blue. The extremely small LED die have a footprint of only 0.2mm x 0.2mm, which makes them a perfect fit for low profile electronic wearable applications.

Plessey's VP of Sales, Giuliano Cassataro, said, "We continue to win designs in the growing market for wearables and are now producing millions of LEDs every month. Our dotLED product range addresses the optical, mechanical and cost requirements for the typical wearable applications. These include wristbands trackers for health and fitness as well as many other applications for dot matrix displays."

The white dotLED is available in a 1005 SMT package (1.0mm x 0.5mm), which is a standard electronic component size easily handled by standard surface-mount machines used in high volume, consumer electronics manufacturing. Delivering up to 1.0Lm of white light with a 130 degree viewing angle from a 5mA drive current, the PLW13D003 meets the demand for ever smaller displays. A blue version, the PLB13D003 is also available in a variety of wavelengths from 460nm to 480nm.

Dr. Keith Strickland, Plessey's CTO, said, "The increasing popularity of our dotLEDs has led us to develop our first chip scale package (CSP) solution around the fit and performance of this product range. Samples for this even smaller form factor will be available September this year in a selection of temperatures and colours."
