    Abstract: A display device or the like with a novel structure which can ensure a sufficiently long period for writing data signals in pixels is provided. A display device or the like with a novel structure which can display an image of one frame without greatly degrading display quality is provided. The display device includes a gate driver and a pixel portion. The pixel portion includes a plurality of pixels. The gate driver is configured to output a first scan signal to a first gate line in a first frame period. The gate driver is configured to output a second scan signal to a second gate line in a second frame period. The second gate line is a gate line next to the first gate line. The pixels are configured to hold data signals, which are written in the pixels in the first frame period, in the first frame period and the second frame period.

    Abstract: A highly reliable semiconductor device is provided. The semiconductor device includes first to third transistors and a capacitor. In the first transistor, one of a source and a drain is supplied with a first signal, the other of the source and the drain is connected to a gate of the second transistor and one electrode of the capacitor, and a gate is supplied with a second pulse signal. In the second transistor, one of a source and a drain is supplied with a first pulse signal, and the other of the source and the drain is connected to the other electrode of the capacitor and one of a source and a drain of the third transistor. In the third transistor, the other of the source and the drain is supplied with the first potential, and a gate is supplied with a second signal that is an inverted signal of the first signal. The first pulse signal is a clock signal, and the second pulse signal has a duty ratio of 55% or lower.

    Abstract: An electronic device using a novel optical module is provided.The optical module includes a first light-emitting element, an optical conversion element, and a first light-receiving element. The first light-emitting element includes a plurality of fluorescent substances and a light-emitting diode. The optical conversion element includes a first optical filter. The light-emitting diode emits first light, and the fluorescent substances can emit second light by being excited by the first light. The first optical filter can form third light having a wavelength range longer than 680 nm from the second light. The first light-receiving element has the function of detecting the third light, and the first light-receiving element functions as a sensor detecting the existence of a shielding object on a light path connecting the first light-emitting element and the first light-receiving element. Furthermore, the second light formed by the optical module can function as a light source of the display device.
