Abstract: An arrangement of spacer posts in a flat panel display. The spacer posts maintain a fixed separation between a back plate and a face plate. The back plate includes one or more electron emission sources. Phosphors or other electro-optic material are distributed among a plurality of pixel areas on the face plate. The pixel areas are arranged in distinct groups, where each group contains N adjacent pixel areas. Each pixel area includes an area free of phosphor material. Within each group of N pixel areas, the respective phosphor-free areas of the N pixel areas are contiguous so as to form a combined phosphor-free area equal to or greater than the transverse cross-section of one end of a spacer. Consequently, a spacer can be attached to the face plate at each combined phosphor-free area without disrupting the uniformity of the distribution of phosphors on the face plate.

Abstract translation: 平板显示器中间隔柱的布置。 间隔柱在背板和面板之间保持固定的间隔。 背板包括一个或多个电子发射源。 磷光体或其他电光材料分布在面板上的多个像素区域中。 像素区域被布置成不同的组，其中每个组包含N个相邻像素区域。 每个像素区域包括没有磷光体材料的区域。 在N个像素区域的每组中，N个像素区域的各个无磷区域是连续的，以形成等于或大于间隔物一端的横截面的组合的无磷区域。 因此，可以在每个组合的无磷区域的情况下将间隔件附接到面板，而不破坏荧光体在面板上的分布的均匀性。
