ABSTRACT:
The invention provides a driving method of a semiconductor display device in which generation of a pseudo contour can be suppressed while the operating frequency of a driver circuit is suppressed. Furthermore, the invention provides a driving method of a semiconductor display device in which generation of a pseudo contour can be suppressed while the decrease in image quality is suppressed. In a semiconductor display device including a plurality of pixels, tables each storing data for determining a subframe period for light emission among a plurality of subframe periods are provided for a plurality of arbitrary pixels among the plurality of pixels respectively. The table is stored in a memory.
