LG gets in on the flexible display act

AUTHOR: Inavate

LG Display has announced its development of a newspaper-size flexible e-paper. The 19-inch wide (250x400mm) flexible e-paper is almost as big as a page of A3 sized newspaper. The product is optimised for an e-newspaper and able to convey the feeling of reading an actual newspaper. Additionally, as the product measures 0.3 millimeters thin, the e-paper weighs just 130 grams despite its 19-inch size.

LG Display has arranged TFT on metal foil rather than glass substrate, allowing the e-paper display to recover its original shape after being bent. The use of a metal foil substrate makes the e-paper both flexible and durable while maintaining display qualities.

The company has applied GIP (gate-in-panel) technology which integrates the gate driver integrated circuits (Ics) onto the panel. This improves its flexibility by removing driver ICs which are attached to the side of panel and hinder the bending of the display.

CTO and executive VP of LG Display, In Jae Chung said, "Our development of the world's largest flexible display has opened up a new market in the next-generation display sector of e-paper. As the e-paper market is growing at a rapid pace, LG Display will continue to deliver new value to customers and the market through industry-leading technologies and differentiated products."

Meanwhile LG Display plans to launch mass production of an 11.5-inch flexible e-paper display in the first half of 2010.

LG Display cited DisplaySearch saying that the e-book market will grow from approximately US$370 million in 2009 to US$1.2 billion in 2011 and to US$1.73 billion in 2015.

Way back in 2007, the then LG.Philips was one of the first company to demonstrate such technology.
