Abstract
Abstract A structure is disclosed wherein several liquid crystal displays are mounted in close proximity to one another without limiting viewing angle. The displays are mounted in a housing with elastomeric connectors and then covered with a mask, which extends over the gap between the displays. The mask is then covered by a glass member, which is held in place on the mask and the liquid crystal display assembly to compress the elastomeric connectors and insure good electrical contact. The resulting display resembles a single large liquid crystal with no degradation of viewing angle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
153 words
A liquid crystal display apparatus comprising: a. a plurality of liquid crystal displays disposed in a proximal coplanar configuration, each display having an annunciator region on a viewing surface thereof and a plurality of electrical contacts on a surface opposite said viewing surface; b. a mask in contact with said viewing surfaces in regions opposite said electrical contacts and voided in regions corresponding to said annunciator regions; c. a printed circuit board providing structural support for said apparatus and electrical communication thereto disposed in a parallel relationship with said liquid crystal displays; d. a plurality of elastomeric connectors intermediate said printed circuit board and said liquid crystal displays providing electrical contact there between; and e. a cover window in contact with said mask on a surface thereof opposite said liquid crystal displays and further having securing means for rigidly attaching said liquid crystal displays, elastomeric connectors, and mask to said printed circuit board.
Claim 2
Dependent Claim
