ABSTRACT:
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.
