<p>A flat-panel display contains a pair of plate structures (20, 22) separated by a spacer (24) having a rough face (54, 56). When electrons strike the spacer, the roughness in the spacer's face causes the number of secondary electrons that escape the spacer to be reduced, thereby alleviating positive charge buildup on the spacer. As a result, the image produced by the display is improved. The spacer facial roughness can be achieved in various ways such as depressions and/or protuberances. Various techniques are presented for manufacturing the display, including the rough-faced spacer.</p> |
