Core Technology

Our technology is based on an elegant, yet highly enabling piece of engineering developed at Oxford University and first published in Nature in 2014 by two of our co-founders. Read here.  

Pigments are not required in our ultra-thin coloured films. No dyes are necessary. Instead, colour is generated by an optical nano-cavity and is then controlled by modulating the refractive index of the active layer (a phase change alloy).

What is more, the phase of the active layer (and the colour) can be switched multiple times using optical, electrical or mechanical impulses.

An illustration of the basic working principle is shown below.

Basic working principle of our technology

 

Bodle Technologies is pioneering this advanced optoelectronic solution for next generation reflective displays. We are able to design our ultra-thin film structures such that white light is reflected back as red, green, or blue — enabling us to create the required colour sub-pixels for a full colour display.

What is more, deposited onto glass our technology can instantly darken in specific regions for localised shading or personal privacy, as well as be used to design dynamic, in-glass colour displays.

The materials we use are well-characterized industrial materials and they are deposited using well-proven manufacturing processes—so they can be easily introduced into practical applications. The core of our innovation lies in the novel way we create our patented ultra-thin film structures. We use our proprietary software to design the multilayer stacks of materials that produce the optical effect required. Our patented control systems then ensure the materials can be switched effectively and reliably multiple times.
