New e-paper displays rich colors and is more economical than analogs

The ink on which the electronic screens are based shows only black and white.However, the new

The technology is able to expand the scope of E-Ink by displaying different colors.An important feature of the improved technology is reduced power consumption.

According to the study authors in the journal Nano Letters, they were helped to create the new electronic paper by changing the order of the layers in the display.

Traditional digital screens use backlighting to illuminate text or images.This technology has its advantages, but it is uncomfortable to look at the screen in sunlight.There is another type of screen that is based on the reflection of light.Reading text from such screens is like reading an ordinary paper book in sunlight.However, until now, such "readers" were only black and white.

The authors of the technology, in addition, inverted the layersdisplay. That is, the conductive layer turned out to be below the pixelated nanostructure responsible for displaying colors, and not higher, as before. The new layer order allows colors to be displayed much more clearly. Screens of this type, as their creators are sure, will find wide commercial use in the foreseeable future.
