A display apparatus is provided which can perform display of high
visibility with the load on a power supply for supplying power to display
elements. A display screen is provided with a plurality of pixels
arranged in an array. Each pixel includes a display element and a driving
circuit for supplying the display element with a current corresponding to
a video signal. A display state detection circuit detects the display
state of the display screen twice or more within a one-frame period. A
dimming circuit varies a current supply time to supply a current from the
driving circuit to the display element, in accordance with an output from
the display state detection circuit, and performs dimming control twice
or more within a one-frame period.
