Plasma display panel emission measurements are correlated with panel efficacy trends, and directions for the improvement of the discharge efficiency are derived. An increase of the ratio of the phosphor emission in the visible to the Xe emission in the infrared indicates an increased Xe excitation efficiency. Also, the time dependence and the spatial distribution of the Xe emission are important discharge characteristics. Experiments reveal that a high panel efficacy is obtained, especially for design and driving conditions that govern a fast and spatially distributed discharge development. A high sustain voltage 200 V causes a "high efficiency discharge mode." It is proposed that in this mode, the cathode sheath is not, or is incompletely, formed during the rise of the discharge current. Then the electric field in the discharge cell is dominated not by the space charges, but by the externally applied voltage. The effective discharge field is lowered, resulting in a lower effective electron temperature and more efficient Xe-excitation. Under the fast discharge buildup conditions also the electron-heating efficiency increases due to a decrease of the ion heating losses in the cathode sheath. A high sustain voltage combines well with a high Xe content gas mixture, that further increases the discharge efficiency. Changes in the phosphor to Xeand Ne-emission ratio show that for higher Xe content, a lower electron temperature accounts for a more efficient Xe excitation. Further, the use of a TiO 2 -layer underneath the phosphor causes an increase of the ratio of the phosphor emission in the visible to the Xe emission in the infrared, i.e., an increased Xe excitation efficiency. As a result, a high efficacy of 5 lm/W and a high luminance of 5000 cd m 2 have been realized in a 4-in color plasma display test panel design with a 50% Xe in Ne gas mixture, a TiO 2 -layer underneath the phosphor, and a high sustain voltage 260-290 V.

“…However, the luminous efficiency of PDPs is still below 2 lm/W, which is considerably lower than those of other displays. There have been many attempts to improve the luminous efficiency of PDPs, such as using gas mixture with high Xe concentration [1], delta arrangement cell with a meander barrier rib [2], waffle-structured rib with 'T'-shaped electrode [3], driving waveform with auxiliary short pulse [4,5].…”

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.

“…The plasma-display panel (PDP) is one of the best candidates to realize the large size and high definition, and it also has predominant advantages in terms of 3-D displays. 1 To improve the luminance and luminous efficacy of PDPs, a high Xe concentration is widely used because it leads to the highly efficient production of excimer VUV radiation. However, this application also brings about the problem of breakdown voltage because it requires a higher electric field for the initiation of the discharge.…”

Abstract— The high‐Xe‐concentration and high‐γ (ion‐induced secondary‐electron emission coefficient) protective layer have been diagnosed from both experimentation and simulation. The experimental results show that there is a great increase in luminance and luminous efficacy, while the breakdown voltage decreases in the high‐Xe and high‐γ discharge. In the high‐Xe discharge, the great increase in VUV radiation mainly results from an increase in excimer VUV emission. The application of high‐Xe concentration can greatly increase the luminous efficacy, while the high‐γ protective layer can promote it further. Considering that the total discharge efficiency can be divided into the electron heating efficiency, the Xe excitation efficiency, and the VUV radiation efficiency, both the electron heating efficiency and Xe excitation efficiency increased for a high‐Xe discharge; while for a high‐γ discharge, the increase in electron heating efficiency contributes to the improvement in discharge efficiency.
