After Apple iPad has transformed black and white e-book reading experience into colorful, page-flipping, and natural book reading experience; display technology is soon to introduce color, flexible e-paper displays! The runaway success of iPad tablet facilitates widening of reader displays from all angles, from width of the display to multifarious brands to introducing e-paper displays devices. The market is growing to accommodate futuristic e-paper display devices with color screen and, a fast display with video support.
Â No backlight, No pain on eyes
The e-paper reading displays will be more soothing for readers as they would mimic â€˜black ink on paperâ€™ appearance of the newspaper with no backlighting to minimize strain on eyes. New generation of such displays would display faster refresh rates, low-power, and better contrast screen. The thickness also seems slashed in the e-paper displays and it has become lighter enough to be held in one hand. Another best feature of the e-paper display is its ability to be viewable even under the bright sunlight, unlike backlit LCD screens. These low-power displays will last for weeks on one time charge and can even continue displaying images when the power is off.
â€˜Ink on Paperâ€™ Experience to push off paperbacks, newspapers
The most popular type of these e-paper displays are rolled in by E Ink that debuts its current generation viz. E Ink Pearl with better contrast ratios and swifter refresh rates. Last November, E Ink has launched Triton featuring color filter overlays to lay a negative effect on the screen which will be contrasted (read compensated) with a brighter background. With wide viewing angle, these displays would soon be made brighter with the addition of color; however, the color production will not be straining and same as the OLED or LCD screens. No wonder, LCD screens will have to contend with e-paper display that already won with readability under sunlight and lesser strain on eyes with actual â€˜ink on paperâ€™ experience. Researches continue to get closer to the printed newspaper with improvements on contrast ratios and screen resolution. E Inkâ€™s latest generation of e-paper displays already topped over paperback novels and newspapers on account of readability.
Flex, Roll & Fold
Not only is E Ink the only pie to vie for, there are two other companies lined up to develop e-paper displays as well. They areQualcomm MEMS Technologies and a startup called Liquavista. Liquavista, has been acquired by Korean electronics giant, Samsung Electronics. With all these electronic heads pushing on the e-paper display technology, there are brilliant advances in e-reader display arena. Besides mimicking the â€˜ink on paperâ€™ look, these displays will also feature flexibility. Unlike stiff LCD glass panels, e-paper displays will be made of a range of surfaces from plastic, glass, fabric, metal foil to even paper to create increased flexibility.Â LG Display has recently demonstrated a prototype of 19-inches flexible e-paper displays which can be flexed without degrading the display quality. Though the first flexible e-paper displays will not land up before 2012 or 2013, we might see similar types of e-readers that attempt to surpass Kindle, Nook, and tablets being sold by Wal-Mart or anybody else for rates as low as 60 bucks.
