Appeal No. 96-1445
Application 08/371,684
whereas Hirsch’s approach disfavored the use of television
type signals through a CRT device, Collender’s device permits
such a signal and type of information to be conveyed in a
three dimensional environment.
The details of the CCDLCLV element discussed have been
known in the prior art beginning at col. 7, line 26 of
Collender. Indeed, this portion, at lines 60 through 63,
makes a specific cross reference to Ernstoff, another
reference relied upon by the examiner in this rejection, by
patent number to provide a color capability to the liquid
crystal matrix array described in that reference. Col. 8,
lines 8 through 12 also indicate that other solid state
imaging surfaces may be used to produce image arrays either by
reflective or transmissive means indicating that the liquid
crystal approach was merely cited as one of those means. To
the artisan, this logically leads to Hornbeck’s teachings.
As to Ernstoff, it appears that each picture element
forming an entire planar color image is formed by three
primary color components using band reflective mirrors such as
dichroic mirrors in the back of the liquid crystal materials
forming the planar matrix array. Each color "cell" in this
