Abstract:
1. A display device comprising: a display element of matrix type; a row driver that drives scan electrodes of the display element; and a column driver that drives data electrodes of the display element, wherein: the column driver includes a matrix driver in a segment mode; the row driver includes a matrix driver capable of being switched between the segment mode and a common mode; and writing of image data to the display element is performed by: invalidating outputs of the row driver and the column driver; setting the row driver to the segment mode; and validating the outputs of the row driver and the column driver after writing selected line specification data to the row driver and writing image data to the column driver, and then setting the row driver to the common mode, a time from completion of the invalidation of the outputs of the row driver and the column driver to a start of the operation to set the row driver to the segment mode is 1 μs or more, a time from completion of the change of the row driver to the segment mode to a start of the write of selected line specification data to the row driver and the write of image data to the column driver is 1 μs or more, a time from completion of the write of selected line specification data to the row driver and the write of image data to the column driver to a start of the change of the row driver to the common mode is 2 μs or more, and a time from completion of the change of the row driver to the common mode to a start of the validation of the outputs of the row driver and the column driver is 1 μs or more.
