Abstract
A faceplate for a field emission display includes a substrate defining a faceplate interior side. Pluralities of phosphor pixels are disposed on the faceplate interior side. A black matrix grid is formed of column and row guard bands on the faceplate interior side. At least one wall gripper is formed in a column or row guard band, with the wall gripper adapted to receive a spacer wall and mount it relative to the pluralities of phosphor pixels. The faceplate can include a faceplate fiducial that optically aligns to a corresponding backplate fiducial. A spacer wall is positioned in the wall gripper and mounted relative to a corresponding locator formed on a backplate interior side. The wall gripper includes a receiving trench that is positioned adjacent to a plurality of deformation accommodation gaps.
