Display device and electronic device

A display device comprising:

• a display panel including a plurality of active elements;
• a driving circuit for driving scanning signal lines and data signal lines both of which are included in the display panel;
• and
• an image processing circuit section for supplying image data and a control signal to the driving circuit, the image processing circuit section including:
• an image optimization circuit for switching, in accordance with an update frequency of the image data, between (i) a first mode in which the driving circuit is driven at a first driving frequency and (ii) a second mode in which the driving circuit is driven at a second driving frequency lower than the first driving frequency,
• in a case where the driving circuit is driven in the first mode,
• the image optimization circuit, in a case where the image data to be transmitted via a transmission path provided between the image processing circuit section and the driving circuit has a data amount that exceeds a maximum transmission capacity for one frame period, carrying out first image data processing for reducing the data amount of the image data so that the image data is transmitted via the transmission path within the one frame period while the driving circuit is driven in the first mode, and
• the driving circuit, in accordance with an image restoration control signal transmitted from the image optimization circuit, carrying out second image processing for restoring, for display, the image data that has been subjected to the first image data processing,
• in a case where the driving circuit is driven in the second mode,
• the image optimization circuit transmitting a control signal for causing the driving circuit to be driven at the second driving frequency so that the image data is transmitted via the transmission path within one frame period while the driving circuit is driven in the second driving mode.
