Summary on Grant Application Form
This Link ISD project involves a partnership between Merck Chemicals Ltd (Southampton), MicroEmissive Displays Ltd (Edinburgh) and Imperial College (London). Merck will develop novel electroluminescent polymerisable liquid-crystal materials (so-called reactive mesogens (RMs)) which can be deposited by solution processing and then polymerised into a cross-linked network by UV exposure. Once polymerised, such materials become insoluble in commonly used solvent systems. MicroEmissive Displays (MED) will develop device processing and manufacturing techniques using direct photolithographic, high-resolution patterning of these materials. IVIED will then develop and manufacture at least a monochrome or ideally a full-colour microdisplay using red, green and blue electroluminescent conjugated network polymers formed from these photopolymerised RMs. Imperial will aid the industrial partners in these objectives by studying these materials and their devices using a range of spectroscopic and electrical techniques. This will give a unique opportunity to investigate the detailed physics of charge injection, transport and light-emission in both large area and very small area polymer LEDs made from this novel class of conjugated polymers, as well as how the photolithographic processing technique effects these materials and device performance. Imperial will also investigate achieving polarised electroluminescence using liquid-crystal RMs, the device physics of two layer devices and the device degradation mechanisms.
