DUAL MODE LIQUID CRYSTAL DISPLAY TECHNOLOGY - Isis Project No 2813
A liquid crystal display device with an ability to switch between a fast response mode and a power saving mode.
MARKETING OPPORTUNITY
Display Search estimates the worldwide market for Liquid Crystal Displays (LCDs) to be in excess of $90 billion by 2009. However, LCDs face stiff competition from other flat panel display technologies such as Plasma, Projection and Organic Light Emitting Diodes. Therefore LCDs must continue to improve in order to maintain leadership. State-of-the-art LCDs have slow Liquid Crystal (LC) response times, which inhibit overall performance. An improvement in this area can potentially increase the overall brightness, colour gamut, resolution and efficiency of the display.
THE OXFORD INVENTION
Oxford inventors have developed an LCD device where fast LC response time of less than 1 ms have been recorded. Furthermore, the device can be switched to a low power bi-stable reflective mode that requires no power at all to keep a particular image displayed on the screen for a very long period of time. The fast transmissive mode is capable of being driven with a colour sequencing backlight where a full color cycle takes less than 3 ms.
The invention makes it possible to
Improved performance
- Increase in the overall brightness
- Increase in the device resolution
- Reduction in the power consumption
Manufacturing simplicity
- Reduction in the transistor elements by a third
- Reduction in the number of processing steps
