Open the CIPO recordAbstract From the Canadian patent
Electroluminescent laminates having a thin film electroluminescent oxide phosphor layer on insulating substrates. Thin film EL laminates are produced using high dielectric constant layers such as SrTiO3 and BaTiO3, next to the oxide phosphor layer on one or both sides of the oxide layer primarily as stable charge injection, and trapping interface layers and to, increase the electric field in the phosphor. Electric breakdown protection through self-healing has been provided by traditional low K dielectrics in combination with an appropriate choice of adjacent electrode. The high dielectric constant materials employed also provide for a high capacitance layer, thereby increasing the electric …

Why it's free to use
- Filed February 23, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 23, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 23, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
