Abstract

According to an aspect, a display device includes: a plurality of pixels aligned in row and column directions, each of the pixels including a drive element; a plurality of scan lines each coupled with the drive elements included in the pixels aligned in the row direction to transmit thereto a scan signal for selecting the pixels row by row; a plurality of signal lines each coupled with the drive elements included in the pixels aligned in the column direction to write display data; and a display control unit. The display control unit alternately repeats a display period and a stop period. In a latter term of the stop period, display control unit provides the display data written in the respective pixels in a row that has been selected during the display period immediately before the stop period, to the signal lines corresponding to the respective pixels.

Claims (14)

1. A display device that displays an image, the display device comprising:

a display area in which a plurality of pixels are aligned in row and column directions, each of the pixels including a drive element;

a plurality of scan lines extending in the row direction, each of the scan lines being coupled with the drive elements included in the pixels aligned in the row direction to transmit thereto a scan signal for selecting the pixels in the display area row by row;

a plurality of signal lines extending in the column direction, each of the signal lines being coupled with the drive elements included in the pixels aligned in the column direction to write display data of the image to be displayed on the display area to the pixels in a row selected by the scan signal; and

a display control unit configured to:

alternately repeat a display period of writing the display data to the pixels in the row selected by the scan signal and a stop period;

in a former term of the stop period, simultaneously set all of the signal lines to have a common predetermined potential; and

in a latter term of the stop period, provide the same display data written in the respective pixels in the row that has been selected during the display period immediately before the stop period, to the signal lines corresponding to the respective pixels except to a signal line to which no display data is written corresponding to a pixel to which the display data is written first in the display period following the stop period.

2. The display device according to claim 1 , wherein, in the latter term of the stop period, the display control unit does not provide the display data to a signal line corresponding to a pixel to which the display data is written first among the pixels arranged in a row to be selected in the display period following the stop period.

3. The display device according to claim 1 , wherein

the display control unit is configured to:

in the former term of the stop period, supply the signal lines with, among pieces of the display data that has been written in the respective pixels in the row that has been selected, a piece of the display data that has been written in a second pixel except a first pixel corresponding to a pixel to which the display data is written first among the pixels arranged in a row to be selected in the display period following the stop period; and

in the latter term of the stop period, supply, among pieces of the display data that has been written in the respective pixels in the row that has been selected, each of pieces of the display data except pieces of the display data that have been written in the first and second pixels, to the signal line corresponding to the pixel in which the piece of the display data has been written.

4. An electronic apparatus comprising the display device according to claim 1 .
