Abstract
A stand-alone spacer for use in a flat-panel display includes a plurality of members being joined at a common axis. A first one of the members is a load-bearing member; a second one of the members is a stabilizing member. The load bearing member extends into the face plate and backplate of the display to provide standoff of mechanical forces. The load bearing member has an aspect ratio within the range of 2:1 to 20:1. The stand-alone spacer has a tipping angle within the range of 20 to 90 degrees so that, after placement on one of the display plates, the spacer is able to remain upright throughout the subsequent packaging and evacuation steps in the fabrication of the display.
Claims9
A stand-alone spacer for a flat panel display having a back plate and a faceplate, said stand-alone spacer comprising:
- a plurality of members having first and second opposed edges, the first opposed edge of each of the plurality of members having a generally flat surface and being positioned in a common plane, the members being joined together at a common axis, a first one of the plurality of members being a load-bearing member and having an aspect ratio in the range of 2:1 to 20:1, the first one of the plurality of members having a maximum height substantially equal to a predetermined spacing between the inner surfaces of the back plate and faceplate of the flat panel display, the stand-alone spacer having a tipping angle in the range of 20-90 degrees so that when the stand-alone spacer is positioned in an upright position on a planar, inner surface of one of the display plates so that the common plane of the stand-alone spacer is in abutting engagement with the planar, inner surface, the spacer maintains its upright position during the subsequent packaging and evacuation steps in the fabrication of the display,
- wherein the load-bearing member maintains the predetermined spacing between the back plate and the faceplate of the flat panel display.
