High luminous efficiency characteristics of alternating current plasma display panel with delta color arrayed, enclosed barrier rib structure

The luminous efficiency characteristics of a new alternating current plasma display panel (ac PDP) structure with the segmented electrodes in delta color arrayed subpixels with enclosed barrier ribs (SDE) are investigated. The SDE structure which has a 4:3 horizontal to vertical cell dimension ratio showed higher luminance and luminous efficiency increment characteristics as the Xe partial pressure increased compared to those of the conventional stripe type with 1:3 ratio for a given resolution. The luminance and luminous efficiency increases with the electrode width, which provides a means to change the color temperature for the full color panel without using other method such as the subpixel size change. The driving feasibility of SDE structure panel with various electrode widths is confirmed by demonstrating the existence of sufficient driving voltage margin.
