  • Patent number: 7378125
    Abstract: The present invention is a method for screen printed lacquer deposition for a display device comprising aligning a mask on top of a faceplate of the display device. Next, the present invention deposits a lacquer material above the mask. Then, the present invention performs a screen printing process to apply the lacquer material through the mask and onto the faceplate to form a lacquer layer on the faceplate. Finally, the present invention dries the lacquer layer.

  • Patent number: 6853129
    Abstract: A protected faceplate structure of a field emission display device is disclosed in one embodiment. Specifically, in one embodiment, the present invention recites a faceplate of a field emission display device wherein the faceplate of the field emission display device is adapted to have phosphor containing areas disposed above one side thereof. The present embodiment is further comprised of a barrier layer which is disposed over the one side of said faceplate which is adapted to have phosphor containing areas disposed thereabove. The barrier layer of the present embodiment is adapted to prevent degradation of the faceplate. Specifically, the barrier layer of the present embodiment is adapted to prevent degradation of the faceplate due to electron bombardment by electrons directed towards the phosphor containing areas.

  • Patent number: 6562551
    Abstract: A multi-level matrix structure for retaining a support structure within a flat panel display device. In one embodiment, the multi-level matrix structure is comprised of a first parallel ridges. The multi-level matrix structure further includes a second parallel ridges. The second parallel ridges are oriented substantially orthogonally with respect to the first parallel ridges. In this embodiment, the second parallel ridges have a height which is greater than the height of the first parallel ridges. Furthermore, in this embodiment, the second plurality of parallel spaced apart ridges include contact portions for retaining a support structure at a desired location within a flat panel display device. Hence, when a support structure is inserted between at least two of the contact portions of the multi-level support structure, the support structure is retained in place, at a desired location within the flat panel display device, by the contact portions.

  • Patent number: 6432593
    Abstract: A multi-level matrix structure for frictionally retaining a support structure within a flat panel display device. In one embodiment, the present invention is comprised of a multi-level matrix structure. The multi-level matrix structure of the present embodiment is comprised of a first multi-layered structure disposed on an inner surface of a faceplate of a flat panel display device. The multi-level matrix structure of the present embodiment is further comprised of a plurality of substantially parallel spaced apart ridges. In this embodiment, the plurality of substantially parallel spaced apart ridges overlie the first multi-layered structure. Additionally, in this embodiment, the plurality of substantially parallel spaced apart ridges include contact portions for frictionally retaining a support structure in a first direction at a desired location within the flat panel display device.
