Abstract: A display device capable of improving image quality is provided. A storage node is provided in each pixel and first data can be held in the storage node. Second data is added to the first data by capacitive coupling, which can be supplied to a display element. Thus, the display device can display a corrected image. A reference potential for the capacitive coupling operation is supplied from a power supply line or the like, and thus the first data and the second data can be supplied from a common signal line.

Abstract: A display device capable of improving image quality is provided. The display device includes a first circuit, a pixel, and a wiring. The first circuit has a function of supplying data to the wiring and a function of making the wiring floating to hold the data. The pixel has a function of taking in the data twice from the wiring and performing addition. The pixel can perform the first writing of the data in a period during which the data is supplied to the wiring, and can perform the second writing of the data in a period during which the data is held in the wiring. Therefore, by one time of data charging to a source line, a data potential larger than or equal to an output voltage of a source driver can be supplied to a display element.

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.
