We investigated the effect of Xe content variation on the luminous efficiency of two different subpixel types, i.e., segmented electrode in delta color arrayed, enclosed subpixel (SDE) and conventional stripe barrier type, in an alternating current plasma display panel through three-dimensional (3-D) numerical simulations. The simulation result agreed well with the experimental result where the SDE structure showed to have higher luminous efficiency improvement with increasing Xe content than the conventional structure did. The conventional cell type was found to have higher vacuum ultraviolet (VUV) generation efficiency at low Xe content as compared with SDE structure, but as the Xe content increased, the SDE type showed a higher improvement in efficiency due to the lower plasma loss to the enclosing surfaces. Using the ray-optics code in conjunction with the 3-D plasma simulation, the transport efficiency of visible light from phosphor through the front plate in the SDE structure, which has a higher aperture ratio, was higher than that of the conventional structure with much increased improvement with the increase of Xe content
