Color displays may one day be used practically everywhere. This would be possible even where it's unprofitable today for cost reasons, such as on food cartons, medicine packaging or even admission tickets.
Imagine food carton labels changing to reflect the expiration, or medicine labels that remind you if and when you've taken your medication and when you need refills, or how about having a concert cancel on you last minute? No need to throw the ticket away, it will automatically change to reflect the new show date.
Siemens developers have produced extremely thin, miniature color displays that can be printed onto paper or foil. The displays run on barely any power and are low cost to produced compared to LCD panels.
The first displays will become available in 2007.
