Philips unveils photonic textiles

12/09/2005

Philips is exhibiting its latest textile breakthrough at the Internationale Funkausstellung (IFA) 2005, in Berlin, Germany - photonic textiles, which are fabrics that contain lighting systems and can therefore serve as displays.

According to Philips, the technology can be integrated into clothing, towels, upholstery, and even curtains to allow them to carry visual displays, without compromising the softness of the cloth.

In order to achieve this, Philips Research and textile institute TITV Greiz have developed an interconnecting substrate made entirely of cloth. Researchers from Philips have also created flexible and drapable substrates from plastics and films.

On these substrates, researchers have placed passive matrices of compact RGB LED packages. The pixelated luminaires with relatively large distance between the RGB pixels have been embedded in such everyday objects as cushions, backpacks, and floor mats. Since the fabric material covering the miniature light sources naturally diffuses light, each pixel seems bigger than it actually is. The LEDs, therefore, remain small and unobtrusive, while the fabric retains its soft look and feel.

Philips has also created interactive photonic textiles by incorporating sensors (such as orientation and pressure sensors) and communication devices (such as Bluetooth, GSM) into the fabric.
