Low Power, Colour Changing Ink

By Halion

Halion has developed a novel liquid ink material which can rapidly change between two colours. The change is actuated with an electric field applied across the ink. Very little power is needed to change the colour, and even less to maintain it.

Reflective Technology Displays

Reflective Technology Just as print media uses a combination of cyan, magenta and yellow inks to produce a broad range of colours, Halion’s ink technology can make use of the same subtractive colour scheme. By combining three layers of ink, each of which switches between colourless and one of these three colours, any colour can be produced on the fly. From black and white to soft pastels and rich hues, all at over 60Hz refresh rate. BATTERY FRIENDLY Using 20x less power than an LCD, our technology enables every surface to become a display. DAYLIGHT VISIBLE Like ink on paper, our displays can be viewed easily both indoors and outdoors. VIDEO CAPABLE Truly engaging experiences are made possible with fast refresh rates. FULL COLOUR Our technology delivers print-like colour quality.
