Enclosed barrier rib structure whose aspect ratio is 4:3 (horizontal to vertical) has shown an extraordinary high luminous efficiency increase compared to that of the conventional stripe cell structure (1:3 aspect ratio) when high Xe content gas or sustain auxiliary pulses are applied. The major reason we concluded through the numerical simulation to explain this phenomenon is the differences in the plasma loss to the barrier ribs. We also carried out experiments applying sustain auxiliary pulses to high Xe content test panels with green phosphor to obtain 6.7lm/W, 2800cd/m 2 under continuous sustaining condition of 50kHz pulses.
