Abstract: An image signal processing circuit is provided that includes a display panel, a current detection section, a modification processing section, and a correction processing section. The display panel includes a first dummy pixel that is provided outside of an effective pixel region. The current detection section detects a change in a current in the first dummy pixel. The modification processing section modifies a predetermined predicted degradation value based on an actual degradation amount of the detected current. The correction processing section corrects an image signal based on the predetermined predicted degradation value after modification. The image signal is used to drive an effective pixel.

Abstract: A display device includes: a display section that has pixels; and a driving section that drives the display section on the basis of luminance information including a plurality of sub-luminance information pieces. The driving section drives the pixels in a time-division manner on the basis of each sub-luminance information piece during a single display period or a plurality of display periods which is set in each sub-luminance information piece. One or both of a timing of start of each display period and the number of the display periods are changeable.
