    摘要： An active matrix type display apparatus in which a plurality of pixel circuits each having an electroluminescent element EL, a 1st FET to control a current flowing in the EL, and a 2nd FET provided between a gate and a drain of the 1st FET are arranged in a matrix, the plurality of pixel circuits arranged in one direction are connected to a data line every column, the 2nd FET is turned on for a predetermined time period, and an image data current flowing in the data line is supplied to the gate and drain of the 1st FET, thereby writing a current value of the image data current. A preliminary charging circuit is connected to the data line. Before the writing operation in the predetermined time period is expired, a current of a predetermined current value is applied to the image data current so that a gate-source voltage of the 1st FET is equal to or larger than a threshold value. Thus, writing imperfection due to a variation in threshold voltage of the 1st FET is solved.

    摘要： A display apparatus includes a plurality of pixels arranged in two-dimensions, each pixel including a pixel circuit and a light emitting element for emitting light at a luminance corresponding to a data signal, a data line, connected to each pixel circuit, for writing the data signal, and a light emitting period control signal line for supplying a light emitting period control signal. Each pixel circuit includes a light emitting element drive unit for supplying a current or voltage corresponding to the data signal to the light emitting element, and a light emitting period control unit for controlling a light emitting period of the light emitting element by the light emitting period control signal. The light emitting period control signals have two or more light emitting period control signals, and the respective pixels are divided into two or more groups by grouping the respective pixels disposed in a same row at least into a same group. Pixels in a same row are scanned in every other row and neighboring rows are sequentially scanned for writing the data signal, and the light emitting elements have an equal light emission duty and are controlled by the light emitting period control signal different on a group basis and controlled so that a time between an endpoint of a writing period within one field period and a start point of a light emitting period within the one field period is different for different groups.

    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.
