    Abstract: A display device includes a display panel and a control circuit which controls the display panel. The display panel includes pixel circuits and one or more dummy pixel circuits. Each pixel circuit includes an organic EL element having a first electrode and a second electrode, and a drive transistor. Each dummy pixel circuit includes a dummy capacitance element having a first dummy electrode, and a second dummy electrode shared with the second electrode of the organic EL element. The control circuit performs at least one of initialization control to initialize a potential of the first electrode in a different pixel circuit and dummy initialization control to initialize a potential of the first dummy electrode in the dummy pixel circuit within a period for which threshold compensation control to compensate for a threshold voltage of the drive transistor is performed on each of the pixel circuits.

    Abstract: An electroluminescent (EL) display apparatus and corresponding method of control are provided. A display screen includes gate signal lines which are arranged to intersect source signal lines. A pixel provided with an EL device corresponds to each intersection of the gate signal lines and the source signal lines. A driving transistor is provided for each pixel to supply a current to the EL device. A first switch transistor is provided for each pixel on a current path through which the current is supplied to the EL device. A gate driver circuit is connected to the gate signal lines. The gate driver circuit is configured to turn the first switch transistor on and off to simultaneously generate band-shaped non-display regions and band-shaped display regions on the display screen and to move the band-shaped non-display regions and the band-shaped display regions relative to the display screen.
