Linux ebook does 9K pages per charge

Sep 16, 2008 — by Eric Brown — from the LinuxDevices Archive

China-based Jinke Electronics is shipping an upgraded version of its electronic book reader that runs Linux. The Hanlin eReader V3 offers an 200MHz ARM9 processor, and a six-inch 800 x 600 display that uses E Ink's power-sipping EPD (electronic paper display) module, says Jinke.

The EPD display offers four shades of gray, and radically decreases display power requirements in mobile devices, claims E Ink. The thin, lightweight display remains legible at high contrast under “any lighting condition,” says the company. Once an image has been “printed,” no power is needed to hold it, reducing energy requirements by 99 percent, compared to LCDs, for some applications, the company says.

E Ink says its electronic ink display technology has appeared in a variety of watches and other consumer electronic products from Seiko, Citizen, and Microsoft. It is also used in Sony's LibriE e-book, which is available in Japan. Linux ebook readers that use E Ink e-paper include the Readius, Amazon Kindle, Bookeen Cybook, eRead Star eBook STK-101, and the iRex iLiad.

The Hanlin eReader V3's 200MHz Samsung ARM9 processor was not further identified, but may be either the Samsung s3c2410 or Samsung S3C2412 system-on-chip (SoC). The device offers 32MB SDRAM, 2MB NOR Flash, an SD slot for up to 4GB of memory expansion, and a USB port.

Located in Tianjin, China, the 200-employee Jinke was founded in 1985, and is a “joint-owned enterprise, which cooperates with Nankai University and the Hong Kong Proud Growth Group,” says the company. Jinke appears to be solely devoted to manufacturing e-book readers, and offers an earlier V2 version that also runs Linux, as well as a version that runs the Wolf operating system (OS). Wolf Linux appears to be Jinke's own distro, which is based in part on Wolf OS.
