Abstract:
1. A display device comprising: a plurality of display pixels that are arranged two-dimensionally and have first light emitting elements; at least one adjustment pixel that has a reference light emitting element; a drive section configured to drive the plurality of display pixels to emit light at respective gradations corresponding to respective video signals input to the plurality of display pixels and to drive the at least one adjustment pixel to emit light at a gradation corresponding to an adjustment-pixel signal; and a processing section configured to set a value of the adjustment-pixel signal during a given field period to be no larger than a largest value of the video signals input to the plurality of display pixels during the given field period, wherein the drive section is configured to apply a display power-supply voltage to the plurality of display pixels when they emit light, the display power-supply voltage is variably set to a value depending on a voltage variation of the reference light emitting element when the reference light emitting element emits light, and wherein the processing section is configured to, during the given field period, update a value of the adjustment-pixel signal every horizontal scanning period such that the value of the adjustment-pixel in the horizontal scanning period in which the update is performed is no larger than a largest value of the video signals input to the plurality of display pixels from the start of the given field period to the horizontal scanning period in which the update is performed.
