    Abstract: An organic EL display device includes a transistor for controlling whether to shut off supply of a current to an organic EL element or not, a pulse signal generation circuit which generates a pulse signal to be inputted to the transistor and a storage unit. The storage unit stores the information in such a way that one frame period includes, in order, a first light emission period which is a period preceding a pulse, a black display period which is a period equivalent to a width of the pulse, and a second light emission period which is longer than the first light emission period, and that an area expressed by a product of a length of and a luminance in a light emission period is greater for the second light emission period than for the first light emission period.

    Abstract: According to one embodiment, a display device displays an n−1th frame (n is an integer which is greater than or equal 2) and an nth frame in this order. The display device includes a display panel, calculator, adjuster, and controller. The calculator calculates power consumption of the n−1th frame. The adjuster determines whether or not the nth frame is brighter than the n−1th frame, and adjusts brightness of the nth frame based on a brightness adjustment magnification of the nth frame calculated based on the power consumption of the n−1th frame and a decreasing function, when the nth frame is not brighter than the n−1th frame. The controller stops light emission with an arbitrary timing when the nth frame is displayed, when the nth frame is brighter than the n−1th frame.
