Abstract: A display device that can display a high-luminance image is provided. The display device includes a display element and a memory circuit which is electrically connected to a first wiring and a second wiring. First, a reference potential is supplied to the first wiring. Next, a first image signal is supplied to the memory circuit through the second wiring. Then, the second image signal is added to the first image signal by supplying the second image signal to the memory circuit through the first wiring. After that, an image obtained by superimposing an image corresponding to the first image signal and an image corresponding to the second image signal on each other is displayed with the display element.

Abstract: An imaging device with low power consumption is provided. The pixel of the imaging device includes first and second photoelectric conversion elements, and first to fifth transistors. A cathode of the first photoelectric conversion element is electrically connected to the first transistor. An anode of a second photoelectric conversion element is electrically connected to the second transistor. Imaging data of a reference frame is obtained using the first photoelectric conversion element, and then imaging data of a difference detection frame is obtained using the second photoelectric conversion element. After the imaging data of the difference detection frame is obtained, a first potential that is a potential of a signal output from the pixel and a second potential that is a reference potential are compared. Whether or not there is a difference between the imaging data of the reference frame and the imaging data of the difference detection frame is determined using the first potential and the second potential.
