Abstract
In flat panel displays wherein thermionic electrons are focused to a narrow beam by means of an anode or gating grids, such grids structures are subjected to temperature deformation and vibratory stress. In high resolution displays individual grid structures are placed in close proximity to similar structures, often less than 0.0265 inch apart. Failure to accommodate physical deformation due to wide variations in temperature and or physical stress caused by shock and vibration will cause the grid wires to short circuit and the display to fail. The invention operates to maintain the relative separation of the individual grid structures within a range of temperatures, shock, and vibration.
