“…Similar results were obtained in the studies carried out by other researchers. 2,5,6 It is well known that a larger gap or a higher Xe concentration results in higher luminance and luminous efficacy within the range between a sustaining voltage and a firing voltage. In this study, the reference case is considered to have a Xe concentration of 10% and a gap distance of 70 lm.…”

“…For example, the luminous efficacy of a LCD TV is about 3 to 5 lm/W. It is well known that high luminous efficacy can be achieved if the number of excited particles is increased by increasing the Xe partial pressure, 2-4 by increasing the gap distance between electrodes, [5][6][7] or by developing a new design for the shape of electrodes or dielectrics. [8][9][10][11][12][13][14] Each of the above mentioned solutions has its own drawback.…”

The results of a two-dimensional fluid simulation of a plasma display panel (PDP) cell show that the discharge characteristics of a coplanar dielectric barrier discharge can be controlled by the electrode tilt angle rather than by the gas mixture ratio or gap distance. The change in the tilt angle results in a significant change in the wall charge distribution and the discharge duration for each pulse. Therefore, the breakdown voltage, plasma density, light brightness, and luminous efficacy can be controlled by the tilt angle. A concave electrode structure allows large wall charge accumulation near the outer edge of two coplanar electrodes, and it results in a long-duration discharge, high luminance, and high luminous efficacy. On the other hand, a convex electrode structure allows high wall charge accumulation near the gap between two coplanar electrodes, and it results in a short-duration discharge with a decreased breakdown voltage.

“…[1][2][3][4][5][6][7][8][9][10][11] Since the discharge characteristics are strongly related to sustain pulse waveforms, the modified sustain pulse waveforms have been proposed to improve the luminous efficiency.

In the previous work, we reported that the luminous efficacy was significantly improved using the short sustain pulse width with sufficiently long off-time between sustain pulses. In this paper, we have proposed the dual sustain pulse as an alternative of short sustain pulse width when the off-time is short. We demonstrate that the luminous efficacy can be significantly improved by using the new dual sustain waveform, which is attribute to the effects of the dual sustain pulse as well as short sustain pulse width when the off-time is 1μs. The proper adjustment of the 1st sustain discharge can induce the 2nd sustain discharge out of the sustain pulse, resulting in the high luminous efficacy. Comparing to the luminous efficacy of the conventional case, it is improved by approximately 130 % due to the effects of dual sustain pulse as well as short sustain pulse width.

“…It has been reported that the luminous efficacy can be improved by using discharge gas with high Xe content 1-3 or a cell structure with a long sustain electrode gap. 4 The mechanism for improving the luminous efficacy, by application of high Xe contents and long sustain electrode gap together, has been investigated previously. 5 It has also been reported that the addition of He to the usual Ne-Xe gas mixture is effective in improving the luminous efficacy.…”

The discharge characteristics of He–Ne–Xe gas mixture in the plasma display panel were investigated using a two-dimensional numerical simulation to understand the effects of adding He and varying the Xe contents in the gas mixture, and also varying sustain electrode gap. With 5% Xe content and 60 μm sustain electrode gap, decreased ionization led to the improvement of the vacuum ultraviolet (vuv) efficacy at increasing He mixing ratios. However, at 20% Xe content and 60 μm sustain electrode gap, increased electron heating improved the vuv efficacy until the He mixing ratio reached 0.7, but the efficacy decreased beyond the ratio of 0.7 due to the increased ionization of Xe atoms. At 5% Xe content and 200 μm sustain electrode gap, the vuv efficacy increased as a result of increased electron heating at the gap space at increasing He mixing ratios.
