Abstract
There is provided a display device that is capable of suppressing occurrence of brightness drop which is caused by refresh of a display image during pause driving. In a normal driving mode, input image data (SsD) according to a continuous tone method is supplied to a source driver () through a data selector () as an image signal (SsD) for driver. On the other hand, in a low-frequency driving mode in which pause driving is performed, the input image data (SsD) is converted into dithered input image data (SsD) by a dithering processing circuit (), and is supplied to the source driver () through the data selector () as the image signal (SsD) for driver. A gradation of the dithered input image data (SsD) is represented in a pseudo manner by an area coverage modulation method by using two values of a maximum value and a minimum value that can be taken as the gradation value of the input image data (SsD).
