Pink
P-Ink (“photonic ink”) is a technology that is used in thin and flexible - electronically controlled - displays , whereby the generation of colors is controlled by photonic crystals .
The color to be displayed is controlled by the distance between the crystals. Depending on this distance, the crystal can only be penetrated by light with a certain wavelength and reflected on the reflective layer behind it. If no voltage is applied, the condition of the crystals and thus the display is maintained for several days, which means that displays with P-Ink technology only require electrical power when switching the display .
The advantage of P-Ink over most other display technologies is that a single image pixel can display multiple colors at the same time without loss of brightness.
The principle was developed at the University of Toronto . In order to be able to develop the technology to market maturity, the company Opalux was founded.
