Las part\u00edculas negras y blancas de esta tecnolog\u00eda responden de manera diferente  a las cargas el\u00e9ctricas negativas y positivas, de modo que la superficie de la  pantalla mostrar\u00e1 blanco o negro dependiendo de cuales surjan y se hagan  visibles. Estas pantallas suelen ser flexibles y utilizan  muy poca energ\u00eda s\u00f3lo cuando la imagen se est\u00e1  escribiendo en la pantalla. Una vez escrita la imagen permanece visible sin  necesidad de una fuente de alimentaci\u00f3n.<\/p>\n<p>Estas pantallas son usadas frecuentemente en los <strong><a href=\"http:\/\/www.idg.es\/pcworld\/Libros-electronicos.-Asi-seran-en-el-futuro\/art200356.htm\" target=\"_blank\">lectores de libros electr\u00f3nicos<\/a><\/strong> como el <strong><a href=\"http:\/\/www.idg.es\/pcworld\/Amazon-presenta-el-Kindle-en-Espana\/doc85957.htm\" target=\"_blank\">Amazon Kindle<\/a><\/strong> o el <strong><a href=\"http:\/\/www.idg.es\/pcworld\/_Analisis_-Libro-electronico-COOL-ER\/art197082.htm\" target=\"_blank\">Cool-ER<\/a><\/strong>. El bajo consumo de energ\u00eda de este tipo de  pantallas es lo que permite a los lectores de libros electr\u00f3nicos que funcionen  hasta un mes entre recargas. Se trata de una tecnolog\u00eda muy diferente a la  utilizada en el Apple\u00a0iPad, que emplea  una pantalla TFT IPS, con un elevado consumo de energ\u00eda y que precisa  retroiluminaci\u00f3n, lo que la hace m\u00e1s inc\u00f3moda a la vista para leer.<\/p>\n<p>Fujitsu ha estado desarrollado pantallas de papel electr\u00f3nico en color durante muchos  a\u00f1os.  Las versiones comerciales de la pantalla deber\u00edan estar disponibles a finales de  este a\u00f1o. Son\u00a0un tercio m\u00e1s brillante debido a los cambios en su construcci\u00f3n y ofrece una  relaci\u00f3n de contraste de 7:1, que es tres veces mayor que la del modelo  anterior. Tambi\u00e9n escribe la informaci\u00f3n en la pantalla a doble velocidad ( importante si tenemos en cuenta que a\u00a0diferencia de las pantallas LCD, la informaci\u00f3n se dibuja en el  <strong>papel electr\u00f3nico<\/strong> a un ritmo mucho m\u00e1s lento).<\/p>\n<p>Recientemente la empresa holandesa Liquavista, tambi\u00e9n anunci\u00f3 avances en este  campo mediante la <a href=\"http:\/\/www.idg.es\/pcworld\/Nuevas-pantallas-pueden-llevar-el-color-y-el-video\/doc93320.htm\" target=\"_blank\">tecnolog\u00eda de electrohumectaci\u00f3n<\/a>, que permitir\u00eda hacer  pantallas para libros electr\u00f3nicos que soporten color y v\u00eddeo.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>El papel electr\u00f3nico o E-Ink es un tipo de pantalla que trata de imitar la apariencia de la tinta sobre una hoja de papel.
