Latest Patents

One of Macaulay's latest patents addresses the fabrication of flat-panel displays with a unique spacer design aimed at inhibiting secondary electron escape. This patent outlines a process where a spacer with a rough face is placed between two plate structures. The roughness of the spacer's surface minimizes the number of secondary electrons that can escape when impacted by electrons, reducing positive charge buildup and thus enhancing the overall image quality of the display. The facial roughness is achieved through various methods, such as incorporating suitable depressions or protuberances on the spacer.

Another significant patent is focused on a method for creating gated filament structures for field emission displays. This innovation involves a multi-layer structure composed of a substrate, an insulating layer, and a metal gate layer. The process includes forming patterned gates that define a plurality of gate apertures, utilizing spacers as masks for etching the insulating layer. This leads to the formation of pores plated with filament material, ultimately creating a network of filaments crucial for high-performance display technologies.
