e-book readers push the EPD technology

It is not precise far away that instead of searching for newspapers in the morning you will have to just switch on your e-book reader. The new gadgets, Amazon’s Kindle $ Sony Reader 505, have revived the long under performing e-book readers. These inclination has encouraged the use of lectronics paper display (EPD) technology.

The EPD displays currently state used are based on lectronics “ink” developed by E Ink Corp. The ink used is bi-stable and is precise energy efficient. The advantages of EPD displays over LCD displays include the lower duty of energy and that the reflective surface of the EPD displays makes them legible even in daylight. In future the e-paper displays will be flexible as the EPD technology will use plastic substrates instead of the solid substrates.

EPD screens resolution is rapidly improving. The current generation of e-book readers use active-matrix displays and can offer relatively high resolutions. The Kindle screen displays 167 ppi or pixels per inch, while Seiko Epson Corp. recently showed off a 13.4 inch displaying about 385 ppi, that uses E Ink’s electrophoretic ink on a silicon thin-film transistor solid substrate.

A number of user products, such as watch dials, cell phones, credit cards, security cards, etc are motion up using the EPD technology. The technology is also state used in artifact applications, like the capacity meter on Lexar JumpDrive USB drives, and in signage.

However redrawing an representation on an EDP takes longer than it does on an LCD screen. It makes this technology unfeasible for animation. Because EPDs are reflective, signage needs to be illuminated in dark areas. And screen contrast is large indefinite quantity lower than it is with backlit LCD screens.
