    Abstract: An imaging device with low power consumption is provided. It includes a pixel capable of outputting difference data between two different frames, a circuit determining the significance of the difference data, a circuit controlling power supply, an A/D converter, and the like; obtains image data and then obtains difference data; and shuts off power supply to the A/D converter and the like in the case where it is determined that there is no difference, and continues or restarts the power supply to the A/D converter and the like when it is determined that there is a difference. Determining the significance of the difference data can be performed row by row in a pixel array or at nearly the same time in all the pixels included in the pixel array.

    Abstract: A display device with a narrower frame can be provided. In the display device, a first layer, a second layer, and a third layer are provided to be stacked. The first layer includes a gate driver circuit and a data driver circuit, the second layer includes a demultiplexer circuit, and the third layer includes a display portion. In the display portion, pixels are arranged in a matrix, an input terminal of the demultiplexer circuit is electrically connected to the data driver circuit, and an output terminal of the demultiplexer circuit is electrically connected to some of the pixels. The gate driver circuit and the data driver circuit are provided to include a region overlapping some of the pixels. The gate driver circuit and the data driver circuit have a region where they are not strictly separated from each other and overlap each other. Five or more gate driver circuits and five or more data driver circuits can be provided.

    Abstract: A flexible semiconductor device including a light-emitting element and a sensor element is provided. The semiconductor device includes a sensor device, a processor, and a communication device. The sensor device includes a first pixel and a second pixel formed over a flexible substrate. The first pixel includes a light-emitting element and a first transistor. The second pixel includes a sensor element having a photoelectric conversion function and a second transistor. Light emitted from the light-emitting element has a peak wavelength. A range of wavelength sensed by the sensor element includes the peak wavelength. A semiconductor layer of the first transistor and a semiconductor layer of the second transistor include the same element. A pixel electrode of the light-emitting element has a function of being electrically connected to the first transistor and a function of blocking diffusion light to the sensor element.
