Fujutsu shows bendable e-paper display
I'm a little late on this news, but last week Fujitsu announced a new bendable e-paper technology. EE Times has the most complete technical description I've seen on it:
The display is a passive-matrix, reflective type cholesteric liquid crystal display. Two 3.8-inch diagonal QVGA prototypes, a monochrome display and a color version able to display 512 colors, were shown.
...
Differing from widely used flat displays that have color filters consisting of red, green and blue pixels, the paper display has a three layered structure in total about 0.8 mm thick. One layer consists of two 0.125 mm-thick films sandwiching liquid crystal. Cholesteric crystals in each layer are twisted in a certain pitch to reflect only red, green or blue light respectively.
Images on the screen can be changed with 10-milliwatts to 100-milliwatts depending on scanning speed.
