Abstract: A display device includes a driving controller configured to receive an input image signal and to output an output image signal, a data driving circuit configured to output a data signal to correspond to the output image signal, and a display panel including a plurality of pixels configured to display an image corresponding to the data signal. The driving controller includes a moving picture accumulator configured to receive the input image signal and to output an accumulation image signal obtained by accumulating the input image signal for an accumulating time, a moving picture average calculator configured to output an average image signal by dividing the accumulation image signal by the accumulating time, and a normalizer configured to output the output image signal by normalizing the average image signal, based on the maximum reference brightness of the display panel.

Abstract: A transistor is disclosed that includes a substrate, an active layer, a gate electrode, a first electrode, a second electrode, and a first connection electrode. The active includes a first region, a second region, and a channel region between the first region and the second region. The gate electrode is disposed on the active layer and overlaps the channel region. The first electrode is disposed on the substrate and electrically connects to the first region. The second electrode is disposed on the substrate and electrically connects to the second region. The first connection electrode is disposed on the substrate and electrically connects the gate electrode and the second electrode.
