ABSTRACT:
A cold cathode flat fluorescent lamp (CCFFL) comprising a flat lamp chamber, fluorescent substance, discharge gas, and a patterned electrode is provided. The discharge gas is disposed in the gas discharge chamber. The fluorescent substance is disposed over the inner wall of the gas discharge chamber. The patterned electrode is disposed over a surface of the flat lamp chamber. In an embodiment, the patterned electrode comprises anode pairs and cathode pairs which are alternately arranged. Each anode pair comprises a first meandering anode with first protrusions and a second meandering anode with second protrusions, wherein the first protrusions and the second protrusions are staggered. Each cathode pair comprises a first meandering cathode with third protrusions and a second meandering cathode with fourth protrusions, wherein each third protrusion aligns with each second protrusion, and each fourth protrusion aligns with each first protrusion.
