A MIM driven Display with Colour Filters on 2″ diagonal Plastic Substrates

AbstractWe report an active‐matrix display with colour filters presumably using plastic substrates for the first time. The fabrication and characterisation of Ta2O5 based and bridge type MIM devices applying an TaAl alloy as new ductile bottom electrode material is described. The realisation of the corresponding low temperature absorptive colour filter, the TN‐cell assembly and TAB bonding techniques on polymer substrates are presented.

A new H10-to-H20 mode transducer

Using a general method of mode-transducer design previously described, a simple H10-to-H20 mode transducer was constructed. The reflection coefficient is calculated, and it is shown that for a transducer a few wavelengths in length the reflections are insignificant. The power transferred to the spurious modes was measured by the resonance method on two experimental models, 2 and 8 guide-wavelengths long. The longer transducer transforms 92% of the power into the required mode. The power in unwanted modes can be greatly reduced by the use of a simple absorptive mode filter.
