Philips turns fabrics into intelligent displays

Don't be surprised if someday in the bar or hotel lobby, the pillows or drapes in front of you suddenly light up and display some luxury goods. At the IFA consumer electronics show in Berlin, Philips Electronics is demonstrating new photonic textiles, or fabrics that contain lighting systems made up of compact light-emitting diodes (LEDs) that can serve as interactive displays, among other things.

Researchers at Philips and the textile institute TiTV Griez in the Netherlands have developed an interconnecting substrate made entirely of cloth, as well as flexible and drapable substrates from plastics and films. On top of these substrates, they have placed passive matrices of compact RGB (red, green, blue) LED packages.

Since the fabric material covering the miniature light sources naturally diffuses light, each pixel seems bigger than it actually is. As such, the LEDs remain small and unobtrusive, while the fabric retains its soft look and feel.

To make photonic textiles interactive, Philips has incorporated sensors and wireless communication devices, such as short-range Bluetooth and cellular Global System for Mobile Communications (GSM) into the fabric.

The Dutch consumer electronics giant sees demand for photonic textiles in application areas such as lighting, communications and health care.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
