ABSTRACT:
The invention provides a display device and an electronic apparatus which can reduce power consumption in the case of being driven by using a digital time grayscale method. According to the invention, a row in which all the pixels display black is focused on in a plurality of pixels arranged in matrix, and sampling of data which is to be inputted to the pixels arranged in the row is not performed. Then, in a period during which the data sampling is not performed, the operation of a shift register in a source driver and sampling operation of a video signal in a first latch circuit are stopped. The invention which has the aforementioned characteristics can temporally stop operation of the source driver to reduce power consumption. In particular, the invention can stop operation of the source driver which consumes much power in the display device, leading to dramatic reduction in power consumption.
