Abstract

See full text

A display apparatus includes a plurality of light emitting devices arranged in row and column directions, drive circuits for driving the light emitting devices, a plurality of scanning lines and a plurality of lighting lines connecting the drive circuits in the row direction, a plurality of data lines connecting the drive circuits in the column direction, and a control circuit for controlling the scanning lines, the lighting lines, and the data lines. The control circuit performs at least twice, while performing a first programming scanning and a second programming scanning respectively once, a light emitting scanning in which the plurality of lighting lines are sequentially selected and currents corresponding to the signals set to the drive circuits are supplied from the drive circuit connected to the selected lighting lines to the light emitting devices. In addition, the control circuit varies the length of a period for which the currents are supplied from the drive circuits connected to the selected lighting lines to the light emitting devices every time the light emitting scanning is performed at least twice.
