Appeal No. 96-0871
Serial No. 08/177,858
by the Examiner. Claims 2 and 8 through 11 have been
canceled.
The invention relates to backlit liquid crystal display
devices (LCDs) having a first light source for operation
during the day, and a separate and independent second light
source for operation at night. On page 42 of the
specification, Appellant discloses that Figure 10 illustrates
the proper positioning of an integral image-
splitting/collimating lens 302, an EL night lamp 398 and a
serpentine daytime lamp 300. In particular, on pages 43 and
44 of the specification, Appellant discloses that the spacing
between the parallel daytime light sources 300 is an important
parameter to the achievement of substantially uniform light
from either the daytime light sources 300 or the EL night lamp
398. Appellant discloses that by manufacturing the
backlighting system so that the inner diameter of the daytime
sources 300, "D ", is equal to the gap, "T", between the inner
I
peripheries of adjacent daytime light sources, the
backlighting from either the daytime light sources 300 or the
EL night lamp 398 results in substantially uniform
