Abstract
A display device includes pixel circuits each including a transistor and supplies a drive current to each light emitting element, scan lines and data lines connected to the pixel circuits, a select driver which selects a scan lines, and a control unit which controls driving of the select driver. The control unit repeatedly executes a gradation display operation, a non-gradation display operation and a detecting operation in the order. In the gradation display operation, a gradation display voltage is applied to the pixel circuit connected to a selected scan line. In the non-gradation display operation, a non-gradation display voltage is applied to the pixel circuit connected to a selected scan line. In the detecting operation, a characteristic of the transistor of the pixel circuit connected to one or more scan lines is detected to correct the gradation display voltage based on a detection result of the detecting operation.
