Abstract
A signal processing circuit includes an accumulator circuit that accumulates display history information regarding light-emitting devices, and a detection circuit that detects the degree of deterioration of a display panel by the accumulated display history information and detects a rotation-recommended state of the display panel on the basis of the degree of deterioration. In the case where the display panel is divided into a plurality of blocks each including the same number of pixel circuits, the detection circuit detects the degree of deterioration for each of the blocks, and if the number of the blocks whose degrees of deterioration are greater than or equal to a first threshold value determined in advance is greater than or equal to a predetermined number, detects that the display panel is in the rotation-recommended state.
