Abstract:
1. A display apparatus, comprising: a pixel array section including a driving section configured to drive the pixels through the scanning lines and the signal lines; the driving section carrying out block-sequential driving wherein the scanning lines are grouped in a predetermined number to form blocks and the pixels disposed in rows and columns are sequentially driven in a unit of a block and line-sequential driving wherein the scanning lines are scanned in each of the blocks to sequentially drive the pixels in a unit of a row; the driving section carrying out the block-sequential driving and the line-sequential driving such that the scanning direction of the line-sequential driving is reversed between each adjacent ones of the blocks, and the driving section drives the scanning lines in an order of a first scanning line to a last scanning line in a first block and then in an order of a last scanning line to a first scanning line in a second block adjacent to the first block, wherein the plurality of scanning lines of the pixel array section are divided according to the predetermined number into blocks while scanning periods individually allocated to each group of the plurality of scanning lines is combined to form a composite period including a first period and a second period, and wherein each of the pixels includes a sampling transistor, a driving transistor, a storage capacitor and a light emitting element; the sampling transistor being connected at a control terminal thereof to an associated one of the scanning lines and at a pair of current terminals thereof to a first one of the signal lines and a control terminal of the driving transistor; the driving transistor being connected at a first one of a pair of current terminals thereof to the light emitting element and at a second one of the current terminals thereof to a power supply; the storage capacitor being connected between the control terminal and one of the current terminals of the driving transistor; the driving section including a write scanner for supplying control signals to the scanning lines and a signal selector for switchably supplying a signal potential and a reference potential to the signal lines; the sampling transistor carrying out a threshold voltage correction operation in response to a control signal supplied to the associated scanning line when the associated signal line has the reference potential to write a voltage corresponding to a threshold voltage of the driving transistor into the storage capacitor and then a signal potential writing operation in response to a control signal supplied to the associated scanning line when the associated signal line has the signal potential to sample an image signal from the associated signal line and write the sampled image signal to the storage capacitor; the driving transistor supplying current in response to the signal potential written in the storage capacitor to the light emitting element to cause the light emitting element to emit light; the write scanner selecting the blocks individually for sequential composite periods to scan the pixel array section; the write scanner supplying, within the first period of each composite period, control signals all at once to the predetermined number of scanning lines which belong to one of the blocks to execute a threshold voltage correction operation in a unit of a block; the write scanner outputting, within the second period of each composite period, sequential control signals to the predetermined number of scanning lines which belong to one of the blocks to carry out line sequential scanning thereby to execute a sequential signal potential writing operation in a unit of a row; and the write scanner outputting the sequential control signals such that the line sequential scanning of the scanning lines is carried out in the reverse directions to each other between adjacent ones of the blocks.
