LIQUED CRYSTAL DISPLAY DEVICES WITH STABILISED TRANSIENT STATES - Isis Project No 3512
Liquid Crystal Displays utilising stabilised non-permanent liquid crystal states providing devices that are brighter and have faster response time.
MARKETING OPPORTUNITY
Display manufacturers are committed to continuous innovation and performance enhancement of the Liquid Crystal Displays (LCDs). Conventional LCD devices only employ the permanent states of a liquid crystal (LC). The non-permanent LC states can have improved properties such as sub-millisecond response time and high brightness. However, these LC states are short lived and have not been commercially utilised.
THE OXFORD INVENTION
Oxford researchers have developed a novel polymerisation method that stabilises the non-permanent liquid crystal states and enhances the performance of these LCDs over conventional technology:
- Higher intensity dynamic range
- Lower power consumption
- Faster response time
Figure above compares the intensity dynamic range for conventional and Oxford LC devices (a) ON-state (bright level) at 0 Volts (b) OFF-state (dark level) at 7 Volts.
