Abstract
Abstract The module comprises a carrier on which a semiconductor chip is mounted, and a plurality of terminals to which various outputs of the chip are electrically connected, the terminals comprising metallized areas on one surface of the carrier. A liquid crystal cell is mounted within a frame including means for securing the frame to the carrier, resilient connector means being clamped between the liquid crystal cell and the carrier for electrically connecting different ones of the carrier terminals to different ones of electrodes of the cell.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
A liquid crystal assembly comprising: a carrier having a surface and an array of first metallized paths on said surface, a semiconductor integrated circuit mounted on said carrier, different terminals of said circuit being electrically connected to different ones of said first metallized paths, an apertured frame, an electrical connector mounted within said frame, said connector comprising a body of resilient material having an oblong cross section and a plurality of conductive lines on the outside surface of said body wherein the width of said conductive lines is less than the spacing between adjacent ones of said first and second metallized paths, a liquid crystal cell comprising a substrate in contact with a liquid crystal material and an array of second metallized paths on an exposed surface of said substrate, and means for mounting said cell and said carrier on opposite sides of said frame with said connector clamped and resiliently deformed therebetween, such that said connector conductive lines resiliently press against each path of a different pair of said first and second metallized paths to provide an electrical connection therebetween.
Claim 2
Dependent Claim
181 words
A liquid crystal assembly comprising: a carrier having a surface and an array of first metallized paths on said surface, a semiconductor integrated circuit mounted on said carrier, different terminals of said circuit being electrically connected to different ones of said first metallized paths, an apertured frame, an electrical connector mounted within said frame, said connector comprising a body of resilient material having an oblong cross section and a plurality of conductive lines on the outside surface of said body wherein the width of said conductive lines is less than the spacing between adjacent ones of said first and second metallized paths, a liquid crystal cell comprising a substrate in contact with a liquid crystal material and an array of second metallized paths on an exposed surface of said substrate, and means for mounting said cell and said carrier on opposite sides of said frame with said connector clamped and resiliently deformed therebetween, such that said connector conductive lines resiliently press against each path of a different pair of said first and second metallized paths to provide an electrical connection therebetween.
Claim 3
Dependent Claim
34 words
The assembly of claim 1 in which at the areas of contact of said conductive lines with said metallized paths, the widths of said conductive lines are less than the widths of said paths.
Claim 4
Dependent Claim
29 words
The assembly of claim 1 in which said connector includes a covering sheet of insulating material, said conductive lines comprising metallized areas on the outside surface of said sheet.
Claim 5
Dependent Claim
53 words
The assembly of claim 1 in which said mounting means include a pair of slots formed interiorly of said frame and extending in a direction parallel to said frame side, said connector body including a pair of wires extending outwardly from opposite sides thereof, said wires being disposed relatively snugly within said slots.
Claim 6
Dependent Claim
64 words
The assembly of claim 1 in which said frame is a relatively flat member having upper and lower surfaces, said connector having upper and lower surfaces disposed respectively adjacent to said frame upper and lower surfaces, said conductive lines extending between said connector upper and lower surfaces, and said cell and said carrier engaging a different one of said connector upper and lower surfaces.
Claim 7
Dependent Claim
39 words
The assembly of claim 5 in which said connector upper surface is disposed interiorly of said frame, whereby said connector upper surface, along with an inside surface of said frame, provide a seat for receipt thereon of said cell.
Claim 8
Dependent Claim
46 words
The assembly of claim 5 in which said connector lower surface is disposed, in its undeformed state, exteriorly of said frame and slightly beyond said lower surface thereof, the lower surfaces of said frame and said connector being compressively engaged with said surface of said carrier.
Claim 9
Dependent Claim
38 words
The assembly of claim 7 in which said frame includes downwardly extending pegs extending through openings through said carrier, the leading ends of said pegs being deformed to serve as rivot heads securing said frame to said carrier.
Claim 10
Dependent Claim
36 words
The assembly of claim 1 in which said carrier has a cavity through said surface thereof, said semiconductor circuit is mounted within said cavity, and including a cap bonded to said surface enclosing said semiconductor circuit.
