Appeal No. 2004-1675
Application No. 09/638,214
a driving circuit for driving the self-luminous display
element by controlling the application of a driving voltage to the
self-luminous display element;
a voltage generating circuit for supplying the driving voltage
to the driving circuit;
a constant-current driving circuit for driving the self-
luminous display element at a constant current; and
a voltage detecting circuit for detecting a voltage drop
across the self-luminous display element that is driven by the
constant-current driving circuit; wherein
the driving voltage generated by the voltage generating
circuit is varied in accordance with the voltage drop detected by
the voltage detecting circuit such that the driving voltage is
increased to compensate for deterioration of the self-luminous
display element.
