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.

Abstract: An imaging display device which can quickly display a captured image is provided. The imaging display device includes an imaging portion on a first surface and a display portion on a second surface that is opposite to the first surface. The imaging portion includes a photoelectric conversion element configured to receive light delivered to the first surface. The display portion includes a light-emitting element configured to emit light in a direction opposite to the first surface. A pixel in the imaging portion is electrically connected to a pixel in the display portion. An image signal obtained at the imaging portion can be directly input to the display portion. Accordingly, the time delay due to data conversion can be eliminated, so that a captured image can be displayed in a moment.

Abstract: A display apparatus capable of supplying a high voltage to a display device is provided. A pixel has a function of retaining first data, a function of adding second data to the first data to generate third data, and a function of supplying the third data to the display device. Capacitive coupling by a capacitor is used for data addition. Two pixels provided in the vertical direction (the direction in which a source line extends) share components including the capacitor; thus, the area where the two pixels are provided can be assigned to the capacitor, which can increase the capacitance value. Thus, the data addition by the capacitive coupling can be efficiently performed.
