Abstract: A flat panel display is disclosed which includes a faceplate with a faceplate interior side, and a backplate including a backplate interior side in an opposing relationship to the faceplate interior side. Side walls are positioned between the faceplate and the backplate. The side walls, faceplate and backplate form an enclosed sealed envelope. A plurality of phosphor subpixels are positioned at the faceplate interior side. A plurality of field emitters are positioned at the backplate interior side. The field emitters emit electrons which strike corresponding phosphor subpixels. A plurality of scattering shields surround each phosphor subpixel and define a subpixel volume. The scattering shields reduce the number of scattered electrons exiting from their corresponding subpixel volume. This reduces the number of scattered electrons from charging internal insulating surfaces in the envelope, as well as striking the non-corresponding phosphor subpixels.

Abstract translation: 公开了一种平板显示器，其包括具有面板内侧的面板和背板，背板包括与面板内侧成相对关系的背板内侧。 侧壁位于面板和背板之间。 侧壁，面板和背板形成封闭的密封信封。 多个荧光体子像素位于面板内侧。 多个场致发射体位于背板内侧。 场致发射体发射撞击相应荧光体子像素的电子。 多个散射屏蔽件围绕每个荧光体子像素并限定子像素体积。 散射屏蔽减少了从其对应的子像素体积离开的散射电子的数量。 这减少了从外壳内部绝缘表面充电的散射电子的数量，以及撞击不对应的荧光体子像素。
