Phase change displays could dramatically increase mobile phone battery life and Bodle Technologies has picked up ‘significant’ seed capital to develop them.
Bodle's technology is said to be based on the technology used to make rewritable DVDs using electrical pulses to create vivid displays that require no power and can be viewed clearly, even in direct sunlight.
Since 90% of a phone's power usage is by the screen, the effect of using Bodle's glass will allow phones to be charged once a week.
The glass was invented by Professor Harish Bhaskaran and his postdoctoral researcher Peiman Hosseini. Hoseini is now CTO of Bodle.
The displays are described as appearing 'similar to paper, yet with very high resolution and capable of rendering extremely high-resolution videos that can be seen in bright sunlight.
Professor Harish Bhaskaran said:
"This new approach allows us to create materials which can not only manipulate light very cleverly, but are also very cost-effective. We will be creating smart glazing which allows only certain wavelengths of light into a building, giving instant control over both the heat and light being transmitted, and over the appearance of the glass. We will also be working on other applications for these thin film materials including novel reflective displays and security markings."
"This technology is capable of providing vivid colour displays which appear similar to paper, yet with very high resolution. It is also capable of rendering extremely high-resolution videos that can be seen in bright sunlight."
