P-102: A Study on Plasma Mode and Efficiency of Coplanar and Face-to-Face Electrode Structures in AC PDPs

Abstract

The discharge characteristics of the coplanar and face‐to‐face sustain electrode structures were examined. The visible spectrum (VIS) of a Ne emission of 585 nm and infrared (IR) of 823 and 828 nm were observed under the two different coplanar and face‐to‐face structures of the 6‐inch test panel with non‐phosphor discharge cell. The IR(Xe)/VIS(Ne) plot was used to calculate the discharge efficiency in the PDP‐cell. In a coplanar sustain electrode structure, the intensity ratio between the IR(Xe) and VIS(Ne) was relatively low, whereas in a face‐to‐face sustain electrode structure, the intensity ratio between the IR(Xe) and VIS(Ne) was very high. In a coplanar electrode structure, the distribution of the IR(Xe) and VIS(Ne) was localized on the coplanar electrode near the space between the two sustain electrode, whereas in the face‐to face sustain electrode structure, the distribution of the IR(Xe) and VIS(Ne) was broad over the entire discharge region area. Finally, as a result of the integration of the IR(Xe)/VIS(Ne) distribution, the discharge efficiency of the face‐to‐face sustain electrode structure was improved by about 2.5 times than that of the coplanar sustain electrode structure.

P‐252L: Late‐News Poster: Three Dimensional Spatiotemporal Behavior of Infrared and Visible Emission from Discharge Plasma of AC PDP

“…The visible (585 nm) emission from Ne is related to the ion heating as an energy loss factor, whereas the infrared (823 nm and 828 nm) emission from Xe is closely related to the vacuum ultraviolet as a source of phosphor excitation. Thus, it could be possible to assume that the ratio of infrared to visible emission, IR(Xe)/VIS(Ne), is proportional to the discharge efficiency, as we have previously reported [14]. Figure 5 shows the total amount of infrared and visible emissions from unit cell, which were calculated by the integration of the light emission profiles in Fig 4(b).…”

P‐91: A Study on Discharge Characteristics of Face‐to‐Face and Coplanar Sustain Electrode Structures in 42‐inch Full HD Grade AC PDPs

“…The face-to-face cell structures have been suggested to improve the luminous efficiency of an ac-plasma display panel [1], [2]. The face-to-face sustain electrode structure has shown a high luminous efficiency due to the large gap discharge distance and the improvement of the transmittance for the visible emission caused by the elimination of the ITO electrode and the dielectric layer on the front panel.…”
