Macroscopically sized liquid crystal display |
(57) A large area liquid crystal display (10) in which all of the picture elements (pixels)
(32, 34, 36, 38, 40, 42, 44, 46, 48) thereof are macroscopically sized and operatively
disposed within the correspondingly sized and shaped openings created between the
adjacent rows and columns of a support structure (18). By also utilizing discrete,
large area switching elements (50, 52, 54, 56, 58, 60, 62, 64, 66) such as diodes
or transistors, for addressing the individual picture elements operatively disposed
in any given row or column of the structure, all of the active elements of the large
area display are capable of manual manipulation. In this manner, the cost of even
very large area displays is minimized and inoperative or defective pixels or switching
elements are readily replaceable. The use of V-shaped or "butterfly" lenses (82) about
the e periphery of each of the pixels covers the interstices (72, 74) of the support
structure (18).
