Abstract:
1. A display apparatus, in which a frame is formed of at least a first field and a second field, comprising: 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, wherein the control circuit performs, while providing the data lines with signals, a first programming scanning in which predetermined scanning lines, among the plurality of scanning lines, are sequentially selected and the signals are set to the drive circuits connected to the selected scanning lines in the first field, and a second programming scanning in which scanning lines other than the predetermined scanning lines, among the plurality of scanning lines, are sequentially selected and the signals are set to the drive circuits connected to the selected scanning lines in the second field, the control circuit performs at least once in each of the first field and the second field a light emitting scanning in which the plurality of lighting lines corresponding to all of the plurality of scanning lines are sequentially selected to supply currents corresponding to the signals set to the drive circuits from the drive circuit connected to the selected lighting lines to the light emitting devices, the control circuit controls a length of a first period for which currents are supplied from the drive circuits connected to the predetermined scanning lines selected in the first programming scanning to the light emitting devices to be different from a length of a second period for which the currents are supplied from the drive circuits connected to the scanning lines selected in the second programming scanning other than the predetermined scanning lines to the light emitting devices, in the light emitting scanning performed at least once in each of the first field and the second field, and the control circuit varies the length of the first period and the second period for which the currents are supplied from the drive circuits connected to the selected lighting lines to the light emitting devices, according to the light emission brightness of the light emitting device in the first period and the second period.
