P‐100: A Power‐saving, High Brightness and Uniformity Field Emission Planar Lamp

We successfully fabricated a power‐saving, high brightness and uniformity field emission planar lamp (FEL) by simply screen printing process. In order to maximize the output brightness and reach a good lighting uniformity, we create an innoviative emitter pattern and optimize the FEL assembly process. By the innoviative spiral emitter pattern and optimization assembly process, we fabricated the high brightness and uniform lighting FEL. The lighting area of FEL is 325×37 mm2. The FEL can be operated at DC voltage 6.56 KVwith 2 mA current and the brightness is greater than 28000 Cd/m2.
