Flexible color e-paper with a thickness of 0.29mm: It actually bends like a plastic desk pad.
Bridgestone Corp developed a flexible color electronic paper with a thickness of only 0.29mm.
The company aims to produce it by continuous roll-to-roll processing because the e-paper employs a film substrate. The prototype panel was not manufactured by continuous processing, but the company is reportedly focused on the establishment of a roll-to-toll production system by using the equipment brought in its technical center in Kodaira, Tokyo.
In May 2006, Bridgestone unveiled a flexible e-paper, which was a two-color display unit using Electronic Liquid Powder in two colors sealed in the device. The latest e-paper is capable of displaying 4,096 full-color with the adoption of RGBW color filters combined with the Powder.
Aiming at "producing practical products, not just doing research" (Yoshitomo Masuda, head of the Electronic System R&D Unit at the Electronic Display Laboratory in the Manufactured Goods R&D Division of Bridgestone), the company is now developing roll-to-roll production facilities.
Flexible e-paper will not break even when it is dropped. Emphasizing this strength, as well as its other advantages, Bridgestone is creating new applications with the help of users. The panel will be on display at FPD International 2007 from Oct 24, along with the A3-size full-color e-paper unveiled at the same time.
