Open the CIPO recordAbstract From the Canadian patent
Multilayer anode structures (104) for electronic devices (100) such as polymer light-emitting diodes are described. The multilayer anodes include a high conductivity organic layer (114) adjacent to the photoactive layer (102) and a low conductivity organic layer (112) between the high conductivity organic layer and the anode's electrical connection layer (110). This anode structure provides polymer light emitting diodes which exhibit high brightness high , efficiency and long operating lifetime. The multilayer anode structure of this invention provides sufficiently high resistivity to avoid cross- talk in passively addressed pixellated polymer emissive displays; the multilayer anode …

Why it's free to use
- Filed June 18, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 18, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 18, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
