Popis:	In this study, plasma flat fluorescent lamps (FFLs) having two different types of electrodes (line and cross types) for surface discharge were fabricated and characterized with variation of discharge shape, the distance between electrodes, and mixed gas (Xe-Ar-Ne-He) ratio. The firing voltage in both types of FFLs obeyed Paschen's law. From plasma discharge images, Xe plasma was not uniform compared to Ar, Ne, or He plasmas in a cross type FFL. The cross type FFL using pure Xe gas showed higher luminance due to its larger discharge area and lower luminous efficiency due to its higher current. However the use of 20%Xe-80%Ar gas mixture significantly improved the uniformity and stability of plasma in the cross type FFL, enhancing its luminance and efficiency.
