Large scale electronic display system
First Claim
1. A large area liquid crystal display comprising:
- a substantially rectangular support structure adapted for viewing by a plurality of viewers, and having a viewer proximal and a viewer distal side, said structure comprised of a plurality of elongated triangular members, coated with a reflective material, and arranged horizontally and vertically so as to define an X-Y matrix of substantially parallel rows and columns, the space between each two adjacent horizontal and each two adjacent vertical triangular members defining an opening, and each said opening having a length dimension greater that the width dimension;
discrete liquid crystal picture elements, each liquid crystal picture element adapted to present a large image area to viewers of the information displayed thereupon;
a liquid crystal picture element being operatively disposed in each one of the openings in the X-Y matrix of said support structure;
discrete, electronic switching elements electrically connected to the liquid crystal picture elements for simultaneously addressing specific elements in the rows and columns of the matrix; and
a control optical element operatively disposed adjacent to the viewer proximal side of the support structure, said control optical element comprising a holographic diffuser, and is adapted to control diffusion in both the horizontal and vertical direction.

Abstract
A large area liquid crystal display system in which all of the liquid crystal picture elements are relatively large sized and are disposed the correspondingly sized and shaped openings created between the adjacent rows and columns of a support structure. The support structure is formed of a plurality of vertical and horizontal, elongated triangular-shaped members. The triangular members are coated with a reflective material to enlarge the field of light emanating from each liquid crystal picture element. Control of light from the display is accomplished by a control lens such as a lenticular lens or a holographic lens, while control of incident light is achieved by venetian blind type materials.
