Abstract: A method for using absorbing means for optically coupling substrates together to significantly decrease or eliminate water or like liquid buildup or condensation between the coupled substrates. Two clean substrates are initially provided. A means for absorbing, such a polyvinyl alcohol film, is applied to a first substrate surface. The substrates are then bonded together so that the first substrate surface is in facing relation to the second substrate, and then positioned parallel to each other and in close proximity to each other.

Then, a pressurized means for injecting is filled with the means for optically coupling. The means for injecting then introduces the means for optically coupling within the two substrates from a peripheral edge, thereby allowing the means for optically coupling to permeate throughout the volume between the two substrates.

Abstract: A metallized pattern, used as an electrical conductor, is altered by means of standard lithographic processes to have regions of interspersed missing metal, or voids, in a specified region of the pattern. The voids in the conducting pattern allow radiation, emanating from various angles, to penetrate through the voids so that a glue seal, disposed underneath the pattern, can be exposed to the radiation and thus activated and cured. The preferred application is found in flat panel displays where radiation is required to cure a glue seal that affixes two substrates to one another. The openings in the metallized pattern in the region of the glue seal minimize the shadowing, caused by the solid portions of the pattern, which can result in the lack of glue seal curing or polymerization. The absence of shadowing assures that the glue seal is fully cured and will not contaminate the liquid crystal after final processing.
