E Ink Demos First Active-Matrix Electronic Ink
Engineers at the company have demonstrated what E Ink claims is the first active-matrix electronic-ink display that is capable of producing high-resolution illustrations and text, E Ink says in a statement. The display prototype measures 12.1 inches diagonally with the resolution of a traditional laptop computer, the company says.
The new technology is expected to be available by mid-2003, E Ink says.
In developing the active-matrix screen, E Ink researchers created a new version of electronic ink that changes 10 times faster than the company's current version. The company is currently not disclosing how it made the ink change faster, according to a spokeswoman for E Ink.
Electronic ink is similar to regular ink, but it contains millions of microcapsules. Each capsule contains a mixture of dye pigment and pigment chips. The capsules respond to electronic charges.
The new active-matrix electronic-ink display provides greater readability, uses less power and is thinner and lighter than traditional LCDs, LEDs, cathode ray tubes, and organic light emitting diodes, E Ink says. The technology will be 30 percent thinner and lighter than traditional LCD displays, the company says.
Among E Ink partners are IBM, Lucent Technologies, Motorola, Royal Philips Electronics, and Hearst.
