E-Paper Enters Practical Use
E-paper is being considered for use in not only a few announced applications, but in a wide range of perhaps less obvious applications. Examples of such applications include various cards, such as smart cards and electronic money, displays for devices like universal serial bus (USB) memory, advertising above windows or on hand straps in trains, rear displays on mobile phones, and mobile viewers. E-paper is also being eyed for possible use in products like home appliances and toys.
