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.
Elegant, Easy-to-Use E-Reader
Lose Yourself in Your Reading
The most elegant feature of a physical book is that it disappears while you're reading. Immersed in the author's world and ideas, you don't notice a book's glue, the stitching, or ink. Our top design objective is to make Kindle disappear — just like a physical book — so you can get lost in your reading, not the technology.
Kindle is easy to hold and read. We designed our e-reader with long-form reading in mind. When reading for long periods of time, people naturally shift positions and often like to read with one hand. Kindle's page-turning buttons are located on both sides, allowing you to read and turn pages from any position.
Precise 5-Way Controller
Kindle has an easy-to-use 5-way controller, enabling precise on-screen navigation for selecting text to highlight or looking up words. No on-screen fingerprints.
Never Gets Hot
Unlike a laptop, Kindle never gets hot so you can read comfortably as long as you like.
Kindle automatically detects nearby Wi-Fi networks at school, home, or your favorite café. At a hotel or café that requires a password? Simply enter the password and connect to the network. Once you have added a Wi-Fi network, Kindle will automatically connect to that network the next time you're near the hotspot.
Free Access at AT&T Hotspots
Enjoy free Wi-Fi access at AT&T hotspots across the U.S. for shopping and downloading Kindle content — no AT&T registration, sign-in, or password required.
Adjustable Text Sizes, Font Choices
Kindle has eight adjustable font sizes to suit your reading preference. You can increase the text size of your favorite book or periodical with the push of a button. If your eyes tire, simply increase the font size and continue reading comfortably. Kindle also has three font styles to choose from – all optimized and hand-tuned to provide the best reading experience.
Kindle uses hand-built, custom fonts and font-hinting to make words and letters more crisp, clear, and natural-looking. Font hints are instructions, written as code, that control points on a font character's line, improving legibility at small font sizes where few pixels are available. Hinting is a mix of aesthetic judgments and complicated technical strategies. We've designed our proprietary font-hinting to optimize specifically for the special characteristics of electronic ink.
Faster Page Turns
Kindle now has faster page turns. We've done this by fine-tuning Kindle's proprietary waveform, the series of electronic pulses that move black and white electronic ink particles to achieve an optimal display of images and text.
Support for Non-Latin Characters
Kindle supports the display of non-Latin characters, so you can read books and documents in the translation that's right for you. Kindle displays Cyrillic (such as Russian), Japanese, Chinese (Traditional and Simplified), and Korean characters, in addition to Latin and Greek scripts.
Full Image Zoom
Images and photos display crisply on Kindle and can be zoomed to the full size of the screen.
Rotate Between Portrait and Landscape Mode
Switch between portrait and landscape orientation to read maps, graphs and tables more easily.
Real Page Numbers
Easily reference and cite passages or read alongside others in a book club or class with real page numbers. Using the computing fabric of Amazon Web Services, we've created algorithms that match specific text in a Kindle book to the corresponding text in a print book, to identify the correct, “real” page number to display. Real page numbers are available on tens of thousands of our most popular Kindle books, including the top 100 bestselling books in the Kindle Store that have matching print editions. Page numbers are displayed when you push the menu button.
Carry and Read Your Personal Documents
Kindle makes it easy to take your personal documents with you, eliminating the need to print. You and your approved contacts can e-mail documents - including Word, PDF and more - directly to your Kindle and read them in Kindle format. Your personal documents will be stored in your Kindle library on Amazon and ready to download conveniently anywhere at any time. You can add notes, highlights and bookmarks, which are automatically synchronized across devices along with the last page you read using our Whispersync technology.
You can read your PDFs in their native format, view them in landscape mode, or zoom in up to 300% to view small print and detailed tables and graphics. You can also convert your PDF document to the Kindle format so that it reflows like a regular Kindle book. Learn more
Dictionary and Search
Built-In Dictionary with Instant Lookup
Come across a word you don't know? Kindle includes The New Oxford American Dictionary with over 250,000 entries and definitions for free. Kindle lets you instantly lookup the definition without ever leaving the book – simply select the word with the cursor and the definition will automatically display at the bottom of the screen.
Search Wikipedia and the Web
Kindle makes it easy to find what you're looking for. Just enter a word or phrase and Kindle will search every instance across your Kindle library, in the Kindle Store, on Wikipedia, or the Web using Google search.
Notes and Sharing
Bookmarks and Annotations
Add annotations to text, just like you might write in the margins of a book, with a virtual keyboard that appears just when you need it. And because Kindle ebooks are digital, you can edit, delete, and export your notes. You can highlight and clip key passages and bookmark pages for future use. You'll never need to bookmark your last place in the book, because Kindle remembers for you and always opens to the last page you read.
See what millions of Kindle readers think are the most interesting passages in your books. If several other readers have highlighted a particular passage, then that passage will be highlighted in your book along with the total number of people who have highlighted it.
