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: A display device capable of performing proper display without image signal conversion is provided. In the case of high-resolution display, individual data is supplied to each pixel through a first signal line and a first transistor included in each pixel. In the case of low-resolution display, the same data is supplied to a plurality of pixels through a second signal line and a second transistor electrically connected to the plurality of pixels. When the number of image signals to be displayed is more than one and the image signals support different resolutions, display can be performed without up conversion or down conversion by switching an image signal supply path as described above.

Abstract: A display device capable of improving image quality is provided. The display device is provided with an adder circuit in and outside a display region, and the adder circuit has a function of adding a plurality of data supplied from a source driver together. Components of the adder circuit are divided and partly arranged in the display region. Thus, limitation on the size of the component included in the adder circuit can be eased, and data addition can be performed efficiently. In addition, by providing other components included in the adder circuit outside the display region, the number of wirings in the display region can be reduced and the aperture ratio of the pixel can be increased.

Abstract: A foldable display apparatus with excellent portability is provided. The display apparatus includes a flexible display panel, which can be folded in a small size. The display apparatus has a tri-fold mechanism, in which a region folded with a first surface itself of the display apparatus facing each other and a region folded with a second surface opposite to the first surface itself facing each other can be formed. Thus, even a display panel which has a relatively high aspect ratio can be folded in a small size by provision of a folding crease in the short-axis direction, so that portability can be improved.
