LG. Philips LCD has revealed a 10.4-inch flexible electronic paper module.
Using E Ink Corp.'s electrophoretic ink and LG Philips LCD's thin-film transistor (TFT), the company achieved the flexibility by forming a TFT on a stainless substrate.
The stainless substrate is thinner than 100 μm, resulting in an overall module thickness of only 300 μm. Volume production is slated to start in 2007. The key application of the "Electronic paper" is e-book terminals, although the company intends to develop other applications as well.
LG. Philips LCD newly developed the stainless substrate in an effort to create "flexible" electronic paper. According to the company, TFT forming on stainless substrates is available without upgrading its current TFT manufacturing line.
The module displays monochrome images at four tones, with a contrast ratio of 10:1 and a resolution of 800 x 600 pixels. Operating voltage is 15 V.
