If you're purchasing a device primarily for reading, an important consideration is the screen technology. Unlike devices with LCD screens, Kindle e-readers use the latest generation of Electronic Ink ("E Ink") technology – E Ink Pearl – designed specifically to deliver clearer, sharper text that makes reading for extended periods of time more comfortable. Here are some of the advantages to reading on an E Ink device:
Reads Like Real Paper, Even in Bright Sunlight
E Ink screens look and read just like real paper. Kindle e-readers' matte screens reflect light like ordinary paper and use no backlighting, so you can read as easily in bright sunlight as in your living room. Unlike LCD screens, E Ink screens have no glare.
Easy on the Eyes
E Ink uses actual ink particles to create crisp, print-like text similar to what you see in a physical book. And Kindle e-readers also use proprietary, hand-built fonts to take advantage of the special characteristics of the ink to make letters appear clear and sharp.
• Less eye fatigue: Every time your eye switches from a bright screen to a dimmer, ambient room, your eyes have to 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.
• Reduced glare: All E Ink surfaces are treated to be matte like a printed page, reducing glare and increasing legibility.
• Read in any position: E Ink screens have a uniform contrast ratio that does not change with your viewing angle, so you can read in any position.
• Sharp, clear text: E Ink screens have 100% aperture ratio, so there are no gaps between pixels. The blacks and whites on an E Ink screen are uniform, improving image quality.
Read with One Hand
Ranging from 5.98 ounces to 8.7 ounces, Kindle e-readers are lighter than most paperback books, and weigh half as much as many LCD tablet devices, making it easy and comfortable to hold in one hand for extended periods of time.
Longer Battery Life
Electronic ink screens also have the advantage of significantly lower power consumption than LCD screens. E Ink screens do not require power to maintain a page of text, allowing you to read for up to a month or two on a single charge versus hours on a tablet or smart phone.
