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 image processing is provided. A memory node is provided in each pixel included in the display device. An intended correction data is held in the memory node. The correction data is calculated by an external device and written into each pixel. The correction data is added to image data by capacitive coupling, and the resulting data is supplied to a display element. Thus, the display element can display a corrected image. The correction enables image upconversion, for example.

Abstract: A support for supporting a flexible component is provided. A flexible component support can be folded without decreasing the reliability of the flexible component. The support has a region where two different hinges overlap each other, and bending operation in the region can be performed only in one direction from a flat surface state. Accordingly, even in the case where unintended bending stress is applied to the region in an opposite direction, the flexible component or the support can be protected. In addition, the two hinges can each include position correction mechanism, which enables stable bending operation.

Abstract: A display apparatus capable of improving image quality is provided. In the display apparatus, an adder circuit is provided inside and outside a display region, and the adder circuit has a function of adding a plurality of pieces of data supplied from a source driver. Some components of the adder circuit are separately arranged in a pixel region. Thus, limitation on the size of a component included in the adder circuit can be eased, and data addition can be performed efficiently. In addition, by providing the 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 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.
