LG Display has developed the world's largest flexible e-paper, claim the company in a recent announcement.
The 19-inch wide (250x400mm) flexible e-paper is almost as big as a page of A3 sized newspaper. Approximately eight times larger than e-books of 6-inch class, the product is optimized 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 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 excellent display qualities. In particular, LG Display applied 'GIP (Gate-in-Panel)' technology which integrates the gate driver IC 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.
E-paper is being hailed as a promising new form of public display for offering various advantages compared to conventional LCD or PDP displays. E-paper faces fewer spatial constraints because of its ultra-thin and lightweight form, and reduced maintenance costs due to significantly lower power consumption. Furthermore, the product's flexibility and bendiness enable a wider choice of applications like advertising signs as it can be easily wrapped around pillars and other locations.
LG Display plans to launch mass production of an 11.5-inch flexible e-paper display in the first half of 2010. IDTechEx find that the total market size for e-paper displays in 2010 is $131 million rising to $7.45 billion in 2020. This is the value of the display front plane only - it is not the value of the device the display is sold in. Growth is predominately from demand of e-readers but other applications such as signage and posters will become a substantial market.
