In 2013, CST introduced the CST-01 ultra-thin, flexible E Ink watch. The company later raised over $300,000 in a kickstarter campaign, offering each watch for $129.

Unfortunatly, CST faced production problems, and due to low component yields, and actual price of each watch climbed to $260. CST decided to change its manufacturor (Flextronics), but it is almost out of money.

Researchers from the University of Cincinnati, in collaboration with Merck and HP are developing low-cost large films that can be used to create smart windows that can dynamically adapt for brightness, color temperatures and opacity.

The so-called electro-kinetic pixel technology is based on the electrophoretic principle - the same one used in E Ink panels. The researchers are developing a way to create large-sized sheets of those pixels at low cost.

Two years ago, E Ink announced the Spectra e-paper panels that feature three pigments - black, white and red. Today the company announced an expansion of that product line to include the Spectra Yellow, which can show black, white or yellow colors.

The Spectra panels are aimed for electronic shelf label (ESL) retail applications. E Ink says that red and yellow are two of the most widely used colors relevant to in-store displays and signage. Spectra panels support both active-matrix and segmented format displays.
