Appeal No. 1998-0447
Application No. 08/477,893
of uniform illumination. Claim 1 is illustrative of the
claimed invention, and it reads as follows:
1. An electroluminescent light display assembly
comprising a laminar light screen including
a plurality of close side-by-side thin light emitting
segments independently activatable to produce a display of
light,
a common electrode directly associated with said light
segments,
said light segments comprising electrically activatable
light emitting matter aligned as lines in side-by-side
parallel relation in electrical communication with one surface
of said common electrode,
said line segments including a series of individual thin-
line electrodes each narrower than and directly associated in
coextensive aligned relation with the light emitting matter of
a respective one of said light segments to activate said light
segment,
a power source connected for energization of each of said
light segments,
switching means effective to energize said light segments
in repeated patterned sequence and at a frequency of
repetition of said sequence to produce the visual effect of a
steady unified display of light.
