The low density carbon nanotube forest can provide index match to air, minimizing light scattering, and can absorb most of the light. Such coating can render a 3D object to appear as a 2D flat sheet or make it invisible in the dark background. |
Big and Bright Flexible Displays
Technologe Review - 2007-04-26
Organic light-emitting diode (OLED) displays are attractive because they are bright, efficient, and thin enough to be flexible. But they are currently limited to use in small displays, such as those in mobile phones. That's in part due to the failings of one piece of the device, a transparent electrode used to light up the display. Now researchers at the University of Michigan have developed a new type of electrode that could help clear the way for large, flexible OLED displays. |
Nano Printing Goes Large
Technologe Review - 2009-09-02
A printing technique that could stamp out features just tens of nanometers across at industrial scale is finally moving out of the lab. The new roll-to-roll nanoimprint lithography system could be used to cheaply and efficiently churn out nano-patterned optical films to improve the performance of displays and solar cells. |
A Simpler Route to Plastic Solar Cells
Technologe Review - 2010-06-24
A simplified process for printing polymer solar cells could further reduce the costs of making the plastic photovoltaics. The method, which has been demonstrated on a large-area, roll-to-roll printing system, eliminates steps in the manufacturing process. If it can be applied to a wide range of polymer materials, it could lead to a fast and cheap way to make plastic solar cells for such applications as portable electronics, photovoltaics integrated into building materials, and smart fabrics. |
A Simple Filter Could Make LCDs More Efficient
Technology Review - 2010-08-30
A new type of color filter could significantly increase the energy efficiency of liquid-crystal displays (LCDs), which dominate the market in everything from televisions to cell phones.
The best LCDs today only emit about 8 percent of the light produced by their backlights. This means that they drain batteries in portable electronics and ramp up electricity bills in homes (the California Energy Commission estimates that televisions consume 10 percent of the electricity in homes). |

Colored Solar Cells Boost E-Reader Efficiency and Create Energy-Harvesting Light Displays
The cutting edge - 2011-10-10
A new kind of screen pixel doubles as a solar cell and could boost the energy efficiency of cell phones and e-readers. The technology could also potentially be used in larger displays to make energy-harvesting billboards or decorative solar panels. Jay Guo, a professor in the University of Michigan's Department of Electrical Engineering and Computer Science, has developed the reflective photovoltaic color filter device that can convert absorbed light to electricity. The research is newly published in the current print edition of ACS Nano. |
