Micropoint emissive cathode electron source and field emission-excited cathodoluminescence display means using said source. The source comprises a series of electrodes (5) acting as cathode conductors and carrying micropoints (12) and a series of electrodes (10g) acting as grids, each of the electrodes of one of the series being in contact with a resistive layer (7) and having a lattice structure, so that there are consequently tracks (5a) which intersect and define first openings (6), each of the electrodes of the other series having second openings (11) which are displaced with respect to the first openings.

Why it's free to use
- Filed February 19, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 19, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 19, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
