Abstract:
1. A flat fluorescent lamp (FFL), comprising: a first substrate; a plurality of electrode sets, disposed on the first substrate, wherein each electrode set comprises at least a first strip electrode and a second strip electrode parallel to each other, and the side edge of the first strip electrode has a plurality of electrode branches extending towards the second strip electrode; a patterned dielectric layer, disposed on the first substrate and covering the electrode sets; a plurality of dielectric branches, disposed on the first substrate, and located around the electrode branches; a second substrate, disposed opposite to the first substrate; a plurality of spacers, connecting the first substrate and the second substrate, for forming a plurality of discharge spaces between the first substrate and the second substrate, wherein the electrode sets are respectively disposed in the discharge spaces; and a fluorescent material and a discharge gas, disposed in the discharge spaces.
