indicated at 61, or at its edge or edges 20, indicated at 57
(p. 14, lines 25-28). The phosphors overcome the problem of
restricted viewing angle in LCDs (p. 2, line 8, to p. 3, line 5).
The collimating means can be a grid of apertures in a reflective
layer 21 (Fig. 2; p. 14, lines 2-5); protuberances 47 around the
opening which act as collimating lenses (Fig. 3, p. 14,
lines 5-8); locating the LC material in discrete holes 49 in an
opaque substrate 51 (Figs. 4 and 5; p. 15, lines 10-20); using
etched depressions 81 in the backing layer 17 to scatter the UV
light (Fig. 6; p. 15, lines 21-29); and using lenslets (Fig. 7;
p. 15, line 30 to p. 16, line 3).
Appeldorn '643 discloses an array of notched optical fibers
which emits light from the side of the fibers due to notches.
A lens 32 may be used to redirect the light emitted from the
fiber (Fig. 1; col. 3, lines 60-65).
Claims 1-5, 19, and 20
The rejection
The examiner finds that Crossland discloses a general layout
of pixels in a display including a light-guide backing layer 17,
a luminescent material 35, and a notch 85 forming in the backing
layer 17 and adapted to direct radiant energy within the backing
layer 17 toward the luminescent material 35 (FR3-4). The
examiner finds that the backing layer 17 is a light guide and
