Svelte key fobs flex their muscle

Aug. 21, 2008
Delphi Corp., Troy Mich., is one of the first companies to use next-generation segmented display cells from E Inc. Corp., Cambridge, Mass., for wireless, bidirectional key fobs with long-range car-to-user communication.

The cells are 40% thinner, flexible enough to handle repetitive bends, operate in a wider range of temperatures, and can be cut-toshape.

The displays are readable at an angle of nearly 180° under every light condition from direct sun to low-level ambient. The lightweight, shatterproof plastic cells are conformable, so designers can incorporate curves into consumer electronics, PC-accessories, smart cards, capacity indicators, and electronic shelf labels.

These cells are divided into discrete segments that can be controlled individually to convey information using letters, numbers, and predefined icons. Customers then add drive electronics and use them in their products.

Delphi’s bidirectional key fob’s range is up to 1 km (open-air) and 250 m (from within buildings). The system can lock and unlock doors, open trunks, and handle remote starts.
