Not All E Ink is the Same - Kindle Uses "Pearl", the Latest Generation E Ink for 50% Better Contrast
When considering an ereader, you should ensure that you are getting a device with the latest generation E Ink technology, referred to as "Pearl". Our all-new Kindle uses Pearl, resulting in the best reading experience possible with 50% better contrast and the sharpest text.
PopSci.com named our Pearl display a "Best of What's New 2010" winner stating, "The newest Kindle's most impressive achievement (among others, including a reduced size and a slashed price) is its E Ink Pearl screen, which is just an absolute pleasure to behold."
How Electronic Ink Works
Electronic ink screens work using ink, just like books and newspapers, but display the ink particles electronically. People who see the display for the first time do a double take because the screen looks like real paper.
No Eye Strain - Reads Like Real Paper, Not a Computer Screen
Kindle's electronic ink display is ideal for reading because it does not create the same eyestrain as reading on traditional backlit LCD tablets or laptops.
Clearer Text and the Sharpest Display
Electronic ink uses actual ink to create crisp, print-like text similar to what you see in a physical book. Kindle's proprietary, hand-built fonts take advantage of the special characteristics of the ink to make letters clear and sharp.
No Glare, Even in Bright Sunlight
Kindle's screen reflects light like ordinary paper, eliminating the glare created by backlit LCD displays on tablets or smart phones. Kindle can be read as easily in bright sunlight as in your living room.
Longer Battery Life
Electronic ink screens require no power to maintain a page of text, allowing you to read for up to a month on a single charge versus hours on a tablet or smart phone. This low power consumption also means that Kindle, unlike a laptop, never gets warm so you can comfortably read as long as you like.
Read Before Bed Without Affecting Sleep
According to a recent article in the Los Angeles Times, sleep experts say that reading on closely-held backlit screens before bed inhibits melatonin production, which is critical for a good night's sleep. "The take-home lesson is that insomnia and electronic gadgets emitting light should not [be] mixed before bedtime...Kindle is better for your sleep."
Why is E Ink Easier on the Eyes than LCD?
Here are some of the technical reasons:
- Ambient brightness: Every time your eye switches from a bright screen (like LCD) to the dimmer ambient room, your eyes adjust which may result in fatigue. With E Ink, the page is the same brightness as everything else in the room so there's no adjustment needed.
- No parallax: Parallax is the apparent displacement of an observed object due to a change in the position of the observer. Text on an E Ink screen does not appear to shift at different viewing angles.
- Less glare: All E Ink surfaces are treated to be matte like a printed page. Most LCDs are not, which creates glare and decreases legibility.
- Uniform contrast ratio: The contrast ratio of an LCD varies detectably with viewing angle. E Ink's contrast is uniform, so you can read comfortably at any angle.
- No aperture ratio loss: LCDs have tiny black gaps between each pixel, but E Ink screens have 100% aperture ratio. The blacks and whites on an E Ink screen are uniform, improving image quality.
