“…Figure 9(c) shows that the luminous efficacy decreases with the driving voltage, which has been demonstrated by a number of PDP experiments. [1][2][3][4] It is thus necessary to reduce the driving voltage. The luminous efficacy of a convex structure is almost the same as that of a coplanar structure, while its operation voltage range is much lower than that of a coplanar structure.…”

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.

“…Thus, as the ion mobility increases, the electric field at the cathode sheath is weakened. 2 The changes in the ion mobilities affect the vuv efficacy. Figure 4 shows the potential profiles in the PDP cell for each gas and each gap conditions at the peak of the discharge current.…”

“…The vuv efficacy is proportional to the product of the electron heating efficacy 1 and the Xe excitation efficacy 2 . 2 The electron heating efficacy 1 is the ratio of the power delivered to electrons to the total input power and the Xe excitation efficacy 2 is the ratio of the power consumed by Xe excitation to the power delivered to electrons. Figure 6 shows the incremental ratio of the power delivered to electrons and ions and consumed by excited Xe species with increasing He mixing ratio for each gas and each gap condition.…”

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.

“…[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. [12][13][14][15] Nevertheless, it is still necessary to improve the luminous efficacy to survive in the display market.…”

Improving luminous efficacy using dual sustain pulse waveform associated with short sustain pulse width in AC-plasma display panels

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.
