Abstract
In this work, we have studied the electro-optic characteristics of multi-cell structured, highly efficient Mercury-free Flat Fluorescent Lamp (MFFL). It was found that each cell of the newly suggested multi-cell structured MFFL could be operated independently by the pulse amplitude modulation, and/or pulse width and/or frequency modulation method which can be utilized to make a back light source for LCD with an areal dimming capability. A wide driving voltage margin of stable glow enabled to have a large luminance variation which resulted in the dimming ratio of 14%, while the frequency and the pulse width modulation resulted in the dimming ratio of 25 and 31% respectively. The interconnection of multi-cell structured MFFL for the full size LCD together with its driving wave form for the independent operation of each cell with a 4 bit sub-field method and its consequent 16 level lighting for each TV field are suggested.
