Not all eReading is the Same

There are differences between eReaders and Tablets, and we believe you may want both.  We’ve talked about the benefits of E Ink for readability, but there is also a benefit to eReaders that is harder to quantify; the ability of an Electronic Paper Display to help you focus on content – pulling you into your novel and taking you away from the “real world”.

Paper-Like Reading

If you’ve read about E Ink, you’ve probably heard about the attributes which make our technology unique – paper-like screen, low power, thin form factor… but what does this really mean?

First – let’s get some preliminaries out of the way, for those of you unfamiliar with our technology and how it works.

Our technology is not LCD – and it’s not trying to be.  While there are several different types of LCDs, the basic premise behind them is the same.  To use a very simplified explanation – in Liquid Crystal Displays (LCDs), crystals are suspended between layers of glass – a top plane glass, a TFT glass layer and a polarizer layer.  When a charge is applied by the electronics, the crystals twist.  However, this alone doesn’t allow a viewer to see an image; for that, light is needed.  Most LCDs use a backlight; this light sits behind the TFT and, depending on the crystal’s alignment against the polarizer, will either allow the light to flow through the display, or block the light, thereby making an image visible to you.

In contrast, E Ink displays are made up of literal electronic ink – ink capsules containing black and white pigments that are charged positive and negative, which are then laminated in a single layer onto a film.  That film is then laminated onto a TFT.  When the electronics calls for an image to be displayed, the ink particles move up or down within their capsules, displaying the image for you to see.
