摘要： A display apparatus includes a matrix of light emitting elements, a plurality of drive circuits provided for driving the light emitting elements, a plurality of scanning lines to which a scanning signal is applied to select the drive circuits on a row basis, a plurality of control lines to which a light-emission control signal is applied to determine an emission period of the light emitting elements, and a plurality of data lines to which image signals are applied to define brightness of the light emitting elements on a column basis. The scanning signal is sequentially applied to the scanning lines in a field so that the image signals of the data lines are programmed in the drive circuits, and the light-emission control signal is sequentially applied to the control lines to make the light emitting elements emit light with brightness corresponding to the image signal programmed to the drive circuit. An impulse operation, constituted by a high level and a low level of the light-emission control signal, corresponds to on and off of the light emission element, respectively, and is repeated at least twice in different temporal patterns in a period from programming of the image signal necessary for display of one image to inputting of the next image signal.

摘要： A method for driving a display apparatus uses self luminous elements that allows for favorable display by suppressing a luminance variation accompanying change of a total current amount at a time of on-off drive. In a display apparatus that performs periodic on-off drive, pixels are divided into at least two groups having different light emitting timings with the timing for writing data to the pixels as a reference. Light emission is controlled so that when one group does not emit light, the other group emits light. Alternatively, light emission is controlled so that when one group emits light, the other group does not emit light. In this manner, either the period in which the two groups do not flow current at the same time or the period in which the two groups flow current at the same time hardly exists in one field period.
