Energy Efficient Liquid Crystal Displays
Researchers at the University of Strathclyde have developed a new bistable LCD technology. Being bistable this monochrome LCD does not require constant power to maintain an image but only to change an image. This therefore represents a huge saving in power consumption compared to many existing LCD technologies and is ideal for remote or solar powered applications. With further development the technology will also be capable of colour display.
In addition, because this display is reflective, there is no need for the battery/mains powered backlight that consumes much of the power of a traditional display making it easier to read in direct sunlight. This unique LCD can be manufactured on flexible plastic making it extremely durable and robust and also can be shaped around curved surfaces. The proposed patented design will use a standard and scalable manufacturing process. Key Benefits
- Savings in power consumption as the display only requires power to change the image, not to maintain it, and no battery operated backlight is required
- Low cost manufacture since standard liquid crystal materials and simple manufacturing methods are used
- Robust design using flexible plastics therefore suitable for outdoor signage
- Flexible materials enable it to be shaped around curved surfaces
- Passive addressing increases the resolution of the display
Applications
- Mobile phones, laptop PCs
- Electronic paper
- Smart cards and disposable displays
- Digital Signage
- Outdoor Advertising
IP Status
The technology is protected by a patent application filed by the University of Strathclyde as GB 0611141.3. Contact is welcomed from organisations interested in developing, licensing or exploiting this technology.
