A display has a graphics processor that extracts from image memory just rows that have non-zero luminance information items for the colour under consideration. For each row to be written, the processor sends to a set of N sampling and conversion circuits, at high frequency, a pattern representing the rows to be written, in the form of a succession of N bits. The N samplers successively sample these bits during the succession, to sample and block the bit of rank i in the sampling circuit of rank i, and produce a pattern of N control voltages VGon or VGoff on the rows as a function of the pattern of the received succession, while the graphics processor applies to the columns the luminance data to be written. The operation is repeated solely for the rows that have a luminance information item to be written in the colour under consideration.

In a pixel circuit of an organic EL display device, a voltage of the gate terminal of a drive transistor is initialized before the voltage of a data signal line is written into a holding capacitor via the drive transistor in a diode-connected state. At this time, a current flows from the holding capacitor connected to the gate terminal of the drive transistor to an initialization voltage line via a threshold compensation transistor, a second light emission control transistor, and a display element initialization transistor, and the voltage of the gate terminal is initialized. Thus, an initialization transistor provided between the gate terminal and the initialization voltage line in the related art comes to be unnecessary.
