Liquid crystalline luminophores

Scientists in York have discovered a range of organo-metal luminophores that can emit up to four times as much light than conventional all-organic OLEDs (such as light emitting polymers) by allowing emission from both singlet and triplet states. This offers the potential of brighter displays for the same power consumption or displays with equal brightness for lower power consumption compared to existing technology.

Furthermore, some of the luminophores of the invention have liquid crystalline properties which could lead to further significant increases in energy efficiency through enhanced charge carrier mobility from the ordered structures in the mesophase or by providing polarised emission, offering real advantages for back-lit LCDs.

One family of luminophores displays columnar liquid crystal mesophases. In a second invention, a range of luminophores was discovered with high quantum yields displaying smectic and nematic liquid crystalline phases that are particularly well suited for polarised emission.

Benefits

• Brighter displays with greater energy efficiency
• Lower power consumption.

Applications

Organic light emitting diodes (OLEDs) have applications in flat panel and flexible displays that have lower energy consumption than conventional back-lit liquid crystalline displays. They have multiple other display and lighting applications.
