A closer look at color eReader technology

Posted on Tuesday, January 12 2010 @ 03:36:10 CET by


Technology Review takes a look at the upcoming color eBook reader displays, you can check it out over here.
E Ink's monochrome screens are made up of microcapsules full of positively charged white particles and negatively charged black particles. Applying a negative charge causes a pixel containing the particles to appear white, while a positive charge results in a black appearance. Color versions use the same basic technology, but with colored filters added. Unfortunately, these filters tend to reduce the brightness of the display, leading to a washed out appearance.

Companies such as Pixel Qi, Qualcomm MEMS Technologies, Liquavista, and Kent Displays all have new ideas about the best way to make a good color screen for an e-reader, and they are eager to get in the game..
