Abstract
The discharge characteristics of surface type discharge in Hg-free back light unit (BLU) are examined based on the variations in the discharge gap and gas pressure for scanning BLUs. In particular, the discharge characteristics including the luminance and luminous efficiency are measured relative to the discharge gap and gas pressure. Finally, the dependence of the discharge gap and gas pressure on the surface type ac positive column discharge with two different drivers is analyzed and measured Under the optimal gas pressure and discharge gap with each Xe partial pressure (18 and 30 %), the luminance of 10200 cd/m2 and the luminous efficiency of 27.6 lm/W are obtained for the Xe partial pressure of 18 %, and the luminance of 16490 cd/m2 and the luminous efficiency of 27.3 lm/W are obtained for the Xe partial pressure of 30 %.
