many newer technologies really try to push the boundaries of what can be done and bring the world something that it's never seen before but sometimes some of the most useful stuff can just be a rehash of something that's actually very old sometimes thousands of years old as is the case with electronic ink although we've had paper and ink for a millennia and can read just about anything we want on smartphones or tablets e-readers that use electronic ink or ink instead of fully fledged LCD screens are a very popular choice but Luke why do people even buy these things I mean your Android or iOS device can display ebooks just fine so what's the point well to understand the advantages ink devices have it helps to know a little bit about how they work a standard black and white ink display is made up of millions of very small spheres called micro capsules and are filled with black and white particles of pigment suspended in a fluid white particles carry a positive electrical charge while black ones carry a negative charge when you want to display something like that copy of Fifty Shades that you only read after everyone's gone to bed your e-reader applies different electrical fields to each micro capsule which in turn makes either the white or black particles rise to the top creating text or an image eReader z' can also apply different charges to different sides of a single micro capsule giving capsules a half white half black or grey appearance which can be very useful in increasing resolution by giving the edges two letters and other objects a smoother look the nice thing about this ink suspended in goop system is that once the ink is pushed to the top it stays there without needing any kind of power input the display only draws power when you have to change something on the screen such as going to the next page because simply leaving a page on the screen while you're reading it uses no power unlike an LCD display battery life for readers is often measured in like days or even weeks instead of hours the downside to this of course is just like with real paper you'll need some sort of external light so you can actually you to us on the page summary readers like the popular Amazon Kindle paperwhite have included built-in LED lights for reading after dark which works with a light guide to direct light evenly across the screen so that it's easy for your eyes and convenient but also harder on your battery even so the need for a light source is a worthwhile trade-off for people who want easy portability less eye strain than a typical LCD screen and the same awesome viewing angles you'd get from a gas-station paperback and if you want to do more than just read in black and white there's even color II ink technology that uses other color pigment particles and additional electrodes or color filters on top of the display though it hasn't achieved widespread adoption in the consumer market yet thanks to its ability to hold images for a long time without using electricity electronic ink is starting to find its application in other things other than just ear eaters even flash drives with external displays that are able to display how much capacity is still left inside eing smart watches that don't need to be charged nearly as often as an Apple watch or say galaxy gear there are lots of cool concepts that may become a reality as well such as Ian's credit cards that show your balance on the card in real time and even large scale displays that can even change the appearance of walls or furniture pretty cool maybe one day you'll have an electronic ink couch that can display scenes from your favorite comics but quickly switch off when it's time to bring a date over speaking of switching quickly tunnel bear is a VPN that lets you tunnel to 20
