In an innovative innovation an e-reader that supports video and more over web browsing was recently exhibited by Dutch researchers. It is made and is based upon screen technology and is more energy efficient that LCD screens.

After being successful in e-reader market, Dutch firm Liquavista hopes to integrate it with other devices in future. However, it is doubtful whether this device would be successful in market as a greener gadget. The first e-reader employed with electrowetting technology would be available by the middle of 2011 and then technology would be far better and well spread.

Electrowetting has been known about for more than a century but is only now being perfected by several companies, for instance, to create auto-focus lenses for cameras. Under its technology it uses small electrical charges moving colored oil with each pixel. Presently most of e-readers use e-ink technology where small and black white beads are used with electrical charges.

Presently on an e-book reader it takes up nearly two second to load each page However, the new display can change speed of image upto 60 times per second according to using technology of Electrowetting. This is amply fast enough to run video that requires speed and rate of 50 to 60 frames per second. Liquavista has also used electrowetting for the purpose of adding color to a screen and contrary to liquid crystal displays (LCD) it still works without a backlight.

In Electrowetting new display bounces natural light through oil filters back at the reader, when employed under sunlight the new type of display can bounce the natural light through the oil filters back at the reader. As better the sunshine as better we looks at the image. In dark light, the e-reader switches to the backlight, automatically.

According to Liquavista this technology is three to four time more efficient than LCD screens because of the higher level of backlight crossing through the each of the pixel. Liquavista is exploring with firm Plastic Logic possibility to develop a color magazine that can update itself, automatically.
