In the search for low-cost color displays that do not drain a computer’s battery, the polymer light-emitting electrochemical cell (LEC) may be the next answer to the problem, according to an international team of electrical engineers.
"The color-variable LEC can provide a solution to simple, low cost color displays," Cheng Huang, graduate student in electrical engineering at Penn State told attendees today (Aug. 20) at the 224th American Chemical Society annual meeting in Boston.
Huang, working with Gang Huang, Suzhou University; J. Guo and Chang-Zheng Yang, Nanjing University, and Wei Huang and E.T. Kang, National University of Singapore, investigated color tunable light-emitting devices and the attributes necessary for any organic or polymer electroluminescent device used to provide full-color displays. Devices for flat-panel, full-color displays must have high luminance intensity and efficiency, full-color capability, fast response time and the ability to avoid crosstalk. Also important for these high-performance content displays is the quality of the image on the display, which means high contrast ratio, wide color gamut and long-term stability.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
