Abstract
A method for forming a three-dimensional multi-level conductive matrix structure for a flat panel display device. In one embodiment, the present invention forms first pixel separating structures across a surface of a faceplate of a flat panel display. The first pixel separating structures separate adjacent first sub-pixel regions. In this embodiment, the first pixel separating structures are formed by applying a first layer of photo-imagable material across the surface of the faceplate. Next, portions of the first layer of photo-imagable material are removed to leave regions of the first layer of photo-imagable material covering respective first sub-pixel regions. Then, a first layer of conductive material is applied over the surface of the faceplate such that the first layer conductive material is disposed between the aforementioned regions of the first layer of photo-imagable material. The present invention then removes the regions of the first layer of photo-imagable material leaving only first pixel separating structures formed of the first layer of conductive material, disposed between the first sub-pixel regions. The present invention performs similar steps in order to form s…
