Abstract

The parasitic capacitance between the high voltage electrodes and the backlight housing causes lowering lamp current, electric power leakage, and leading to lower brightness and efficiency in a multi-lamps backlight. In this study a new center balance swing operation method is introduced to be minimizing those housing effects.
