Printable Inks and Binders as Vehicles for Carrying/Depositing Phosphor Nanometer Particles and Ferroelectric Nanometer Particles on Screens for FEDs and EL Devices
Two different vehicles have been designed for carrying and controllably depositing phosphor nanometer and ferroelectric nanometer particles. The first vehicle was an ink that could suspend and deposit phosphor particles that had been synthesized to have sub-micrometer primary particle sizes and narrow size distribution. Aggregation and settlement problems in the inks were addressed and the theological properties of the inks were adjusted to facilitate the printing of phosphors in high resolution pixels. The relative cathodoluminescent intensities across a single pixel, containing the red emitting cubicY2O3 :Eu3+ phosphor powder, were compared to assess the repeatability of the screen-printing of the inks.The second is a binder vehicle which not only carries the electroluminescent phosphor particles that can be up to 30 μm or more in size, but also carries the ferroelectric nanometer particles. This novel binder for AC powder displays was used to form low cost EL displays which require no additional dielectric reflector layers. The emissive layer can be peeled from the substrate as a flexible film which remains EL active when placed between two electrodes. The binder film can be easily screen printed and shaped as desired.
