Abstract
Abstract An LCD support bracket formed by a plurality of resilient cantilever beams projecting from a support to the lower edge of the LCD panel. The opposite edge of the LCD panel is supported by an elastomeric interconnection member that electrically connects the LCD panel to a circuit board on which the elastomeric interconnection panel is mounted. A cover having a viewing window is placed over the LCD panel to hold the LCD panel in place and to preload the resilient cantilever beams. The upper transparent pane of the LCD panel preferably extends beyond the edge of the lower transparent pane so that the resilient cantilever beams and the elastomeric member compress only the upper pane. As a result, the support bracket does not compress liquid crystal sandwiched between the upper and lower panes.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
177 words
A bracket supporting a substantially planar liquid crystal display ("LCD") panel in a cutout formed in a generally planar support, said bracket comprising: a plurality of spaced apart resilient cantilever beams extending from a location of said support that is substantially coplanar with said LCD panel into said cutout and contacting a surface of said LCD panel to support said panel within said cutout, a major portion of said resilient beams extending along a longitudinal axis that is generally parallel to the plane of said LCD panel; support means supporting said LCD panel in at least one other location; and retaining means contacting a surface of said LCD panel that is opposite a surface of said LCD panel that is contacted by said resilient cantilever beams, said retaining means displacing said LCD panel against said cantilever beams with sufficient force to bend said beams so that they are preloaded against said LCD panel thereby shock mounting said LCD panel in said support without preempting the area beneath said LCD panel and the area beneath said cantilever beams.
Claim 2
Dependent Claim
45 words
The support bracket of claim 1 wherein each of said resilient cantilever beams terminate in a projection extending toward and contacting said LCD panel, each of said projections having a rounded end so that there are no sharp corners for said LCD panel to contact.
Claim 3
Dependent Claim
15 words
The support bracket of claim 1 wherein said resilient cantilever beams are four in number.
Claim 4
Dependent Claim
28 words
The support bracket of claim 3 wherein said cantilever beams are arranged in two closely spaced pairs with one pair being positioned adjacent each end of said panel.
Claim 5
Dependent Claim
58 words
The support bracket of claim 1 wherein said support means comprise an elastomeric interconnection member extending from a printed circuit board to a plurality of terminals on the surface of said LCD panel that are contacted by said resilient cantilever beam whereby said elastomeric interconnection member both delivers signals to and supports one edge of said LCD panel.
Claim 6
Dependent Claim
99 words
The support bracket of claim 1 wherein said LCD panel includes a layer of liquid crystal positioned between first and second transparent panes, said first pane having an edge projecting beyond an adjacent edge of said second pane, and wherein said LCD panel is placed in said cutout with said retaining means contacting one surface of said first pane and said cantilever beams contacting a portion of the opposite surface of said first pane that projects beyond the edge of said second pane so that said cantilever beams avoid compressing said liquid crystal between said first and second panes.
Claim 7
Dependent Claim
41 words
The support bracket of claim 6 wherein the ends of said cantilever beams contact the adjacent edge of said second pane thereby restricting movement of said LCD panel in a direction that is parallel to the plane of said LCD panel
Claim 8
Dependent Claim
30 words
The support bracket of claim 1 further including restraining means for restraining said LCD panel from moving in a direction that is parallel to the plane of said LCD panel.
Claim 9
Dependent Claim
52 words
The support bracket of claim 8 wherein said restraining means includes a plurality of ribs extending from said retaining means to at least partially surround said LCD panel so that said ribs can prevent movement of said LCD panel in a direction that is parallel to the plane of said LCD panel.
