As indicated supra, Yuyama describes a self-luminous display
element driving device corresponding to those recited in claims 16,
24 and 32, except for the claimed deterioration information
generating and voltage detecting circuits. Rather than operating a
voltage driving circuit to compensate for the deterioration of the
self-luminous display element determined by the deterioration
information generating and voltage detecting circuits recited in
claims 16, 24 and 32, Yuyama operates the voltage driving circuit
to compensate for the deterioration of the self-luminous display
element determined by a photosensor measuring luminance. However,
Yuyama, like the appellants, recognizes that the luminance of the
LED decreases with time and the current and voltage flowing through
the LED affect the luminance of the LED. Compare the
specification, page 3, with Yuyama, column 1, lines 56-65 and
column 3, lines 27-54. The appellants also acknowledge (the
specification, pages 13 and 16) that
