    Abstract: Malfunction of a large-sized touchscreen is prevented. In particular, malfunction of a large-sized touchscreen is prevented by reduction of wiring delay between a detection region and a controller. In a touchscreen, in which a detection area is divided, including a plurality of detection regions and a plurality of sensors, controllers are provided for the respective divided detection regions, and all the controllers are electrically connected to one central control device. It is preferable that a wiring between each of the divided detection regions and the corresponding controller be shorter than a wiring between the controller and the central control device.

    Abstract: A functional panel is provided. The functional panel includes a first driver circuit, a second driver circuit, and a region. The first driver circuit supplies a first selection signal, the second driver circuit supplies a second selection signal and a third selection signal, and the region includes a pixel. The pixel includes a first pixel circuit, a light-emitting element, a second pixel circuit, and a photoelectric conversion element. The first pixel circuit is supplied with the first selection signal, the first pixel circuit obtains an image signal on the basis of the first selection signal, the light-emitting element is electrically connected to the first pixel circuit, and the light-emitting element emits light on the basis of the image signal. The second pixel circuit is supplied with the second selection signal and the third selection signal in a period during which the first selection signal is not supplied, the second pixel circuit obtains an imaging signal on the basis of the second selection signal and supplies the imaging signal on the basis of the third selection signal, and the photoelectric conversion element is electrically connected to the second pixel circuit and generates the imaging signal.

    Abstract: In order to reduce the frequency of rewriting pixels, gray scales of image signals input to a plurality of pixels provided in a display portion are checked before displaying each image. Specifically, in the case where image signals having medium gray scale levels are input to many of the plurality of pixels, display is performed by normal driving (for example, driving in which rewriting pixels is performed at a frequency higher than or equal to 60 times per second); otherwise, display is performed by driving with a small number of frequencies of rewriting pixels (for example, driving in which rewriting pixels is performed at a frequency lower than or equal to once per second). With this method, an information processing device which can reduce users' eye strain and perform eye-friendly display can be provided.
