Abstract
Abstract A light influencing element and the process of fabricating the same is disclosed, wherein the light influencing element is fabricated by disposing a layer of a substantially opaque material upon a transparent substrate. One or more openings or wells may then be cut or formed in the surface of the layer of opaque material. Into such openings a light influencing material is then disposed, preferable said materials are injected thereinto as by ink-jet type injection heads. Liquid crystal displays and subassemblies formed upon the light influencing elements of the instant invention are also provided.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
203 words
A method of fabricating an element adapted to influence light, said method comprising the steps of: providing a substantially transparent substrate member; disposing a layer of a substantially opaque material upon one side of said substrate; forming at least one opening through said layer of substantially opaque material by providing a high power excimer laser capable of at least micron scale resolution; placing said substrate with said layer of opaque material in close proximity to said laser; providing means for achieving relative movement between said laser and said opaque material coated substrate; employing said laser to cut at least one opening in said layer of opaque material; and disposing a light influencing material in said at least one opening, comprising the further steps of: providing a light influencing material in non-solid phase having the optical characteristics thereof optimized for a desired application; injecting a sufficient amount of said light influencing material into said openings so as to achieve a desired light influencing effect; curing said non-solid light influencing material to the solid phase; providing an infrared oven means; and disposing said substrate, layer of opaque material and light influencing material in said infrared oven means so as to solidify said light influencing material.
Claim 2
Independent Claim
203 words
A method of fabricating an element adapted to influence light, said method comprising the steps of: providing a substantially transparent substrate member; disposing a layer of a substantially opaque material upon one side of said substrate; forming at least one opening through said layer of substantially opaque material by providing a high power excimer laser capable of at least micron scale resolution; placing said substrate with said layer of opaque material in close proximity to said laser; providing means for achieving relative movement between said laser and said opaque material coated substrate; employing said laser to cut at least one opening in said layer of opaque material; and disposing a light influencing material in said at least one opening, comprising the further steps of: providing a light influencing material in non-solid phase having the optical characteristics thereof optimized for a desired application; injecting a sufficient amount of said light influencing material into said openings so as to achieve a desired light influencing effect; curing said non-solid light influencing material to the solid phase; providing an infrared oven means; and disposing said substrate, layer of opaque material and light influencing material in said infrared oven means so as to solidify said light influencing material.
Claim 3
Dependent Claim
36 words
A method as in claim 1, wherein the step of providing a substantially transparent substrate member includes the further step of selecting said member from the group of materials consisting of glass, plastic and combinations thereof.
Claim 4
Dependent Claim
16 words
A method as in claim 1, wherein the substantially opaque material is a black polyimide material.
Claim 5
Dependent Claim
37 words
A method as in claim 1, wherein the step of forming at least one via includes the further step of forming a plurality of similarly sized and shaped vias arranged in a densely packed, uniformly spaced array.
Claim 6
Dependent Claim
67 words
A method as in claim 1, wherein the step of injecting light influencing material into said openings includes the further steps of; providing at least one nozzle for injecting said materials, in close proximity to one of said openings; and providing means for achieving relative movement between said nozzle and said opaque material coated substrate, for disposing light influencing material into each preselected ones of said openings.
