I was just cruising the Philips Applied technology website when I came across this rather interesting development, exploiting Philips expertise in thin film flexible displays and smart card controller chips. It’s a smart card with a display on it.
Philips have set up a start-up Flexible Display Solutions to commercialise the concept, key benefits for the user are increased security and information feedback. Strangely, the original display was a flexible LCD, which, according to another article I read on flexible displays is usually big trouble┬ábut now Philips are targeting an electrophoretic display instead because it is bi-stable – it only needs a signal to switch it = less power consumption. The card is 0.5mm thick and, in addition to the display, contains a control chip and battery.
With rapid development in the area of OLEDs and thermoplastic semiconductors, flexible displays are expected to play an increasing important role in our lives over the next few years as displays become cheap enough to be incorporated into clothing and packaging.
