New Type of Electronic Paper
The new approach, developed by researchers in Germany–at Sony Deutschland Gmb, in Stuttgart, and the Max Planck Institute for Polymer Research, in Mainz–avoids the complications caused by flexible electronics. Their device consists of a chemical layer sealed between plastic sheets. Under normal light, the screen is transparent. But when exposed to infrared light, the chemicals in the screen fluoresce.
To create images, the researchers used a red or infrared laser to quickly scan across the screen, from either in front or behind, causing different parts to fluoresce in sequence to produce a fast-moving image. This is similar to the way that a cathode-ray tube uses an electron beam to make images. In a demonstration, the researchers made a cartoon image move around on their screen.
Tzenka Miteva, a researcher at Sony who coauthored a paper on the technology, published today in the New Journal of Physics, says that the screens use specially-matched combinations of chemicals to “upconvert” light–that is, absorb light of longer wavelengths and emit light at shorter wavelengths. This means that the researchers were able to use a red or infrared laser to generate colors in the visible spectrum. “Red or infrared lasers are cheap and very much available on the market,” Miteva says. “And because it works at very low intensities, we can use them without problems with the viewers.”
Have you considered the possibiity that the light and electrons are the same thing? That frequency is all that matters for energy level. Let the electron mass be constant at h grams. And make the word anthropic mean that our crude molecular measure can only fetch energy where n = 1/h so that energy and frequency are numerically always rhe same as measured. Then E = nhf = f = Mv-squared so that mass is discretely defined in terms of nh–or quantum mass is h grams! With quantum energy at h ergs and quantum mass at h grams, the h-symmetry maks it a piece of cake to predict problematically while never being able to visualize the individual freqency pulse —which is done dererministically by the words above.
