Flexible display
open-in-new
<p>A flexible display or rollable display is an <a href="/facts/Electronic_visual_display/fA0mUcIQ">electronic visual display</a> which is flexible in nature, as opposed to the traditional <a href="/facts/Flat_panel_display/jw0LWETN">flat screen displays</a> used in most electronic devices. In recent years there has been a growing interest from numerous consumer electronics manufacturers to apply this display technology in <a href="/facts/E-reader/D7a76tKm">e-readers</a>, <a href="/facts/Mobile_phone/H3EcqD9h">mobile phones</a> and other <a href="/facts/Consumer_electronics/cJ8g9NXh">consumer electronics</a>. Such screens can be rolled up like a <a href="/facts/Scroll/dcCV0rNQ">scroll</a> without the image or text being distorted. Technologies involved in building a rollable display include <a href="/facts/Electronic_ink/b3JWSLz9">electronic ink</a>, <a href="/facts/Gyricon/KFzUzcGv">Gyricon</a>, Organic LCD, and <a href="/facts/Organic_light-emitting_diode/219L1aMJ">OLED</a>. </p><p><a href="/facts/Electronic_paper/b3JWSLz9">Electronic paper</a> displays which can be rolled up have been developed by <a href="/facts/E_Ink_Corporation/n4lfYdRR">E Ink</a>. At <a href="/facts/Consumer_Electronics_Show/JUmN49Fl">CES 2006</a>, <a href="/facts/Philips/Xp4uczGg">Philips</a> showed a rollable display <a href="/facts/Prototype/q0yPLYdb">prototype</a>, with a screen capable of retaining an image for several months without electricity.<a href="https://en.wikipedia.org/wiki/Flexible_display#endnote_philips">[1]</a> In 2007, Philips launched a 5-inch, 320 x 240-<a href="/facts/Pixel/UzwBvXBV">pixel</a> rollable display based on E Ink’s <a href="/facts/Electrophoresis/B0aLKHTt">electrophoretic</a> technology. Some <a href="/facts/Flexible_organic_light-emitting_diode/q3Yg12e4">flexible organic light-emitting diode</a> displays have been demonstrated.<a href="https://en.wikipedia.org/wiki/Flexible_display#endnote_HP">[2]</a>The first commercially sold flexible display was an <a href="/facts/Electronic_paper/b3JWSLz9">electronic paper wristwatch</a>. A rollable display is an important part of the development of the <a href="/facts/Roll-away_computer/FmFWoCH2">roll-away computer</a>. </p>
