passive display. We have just indicated our view, in
contradistinction to appellant's assertion at the bottom of
page 6 of the Brief that Bly does not teach the use of an
active element as a backlight for a passive display, that it
does in fact show this in Figure 1 anyway. In any event, the
collective teachings of the three references relied upon by
the examiner would have clearly indicated the obviousness of
extending the backlighting teachings of Bly and Shiraishi to
the two dimensional matrix orientations taught by Yoshimura
such as to be able to individually control each of the
individual pixel elements in such a two dimensional array.
Dependent claim 8 recites that the active display device
is controlled in such a manner as to improve luminance
resolution of the entire apparatus. This is generally what
the teachings and showings in Shiraishi indicate since it is
the backlighting active display element in the form of an
electroluminescent backlighting array which is separately
controlled according to the lamp off, the lamp dim, the lamp
standard, the lamp bright codes from the latch 20 through the
decoder 21 and the E-L panel voltage generating circuit 23 in
