    Abstract: A light-emitting device that can switch between two modes: single light emission and intermittent light emission is provided. The light-emitting device includes a driver circuit that can supply a control pulse signal, a constant current power supply that is supplied with the control pulse signal and can supply a constant current pulse, and a light-emitting panel that is supplied with the constant current pulse. The driver circuit includes a start switch circuit that can supply a start signal, a pulse-interval modulation circuit that can supply a pulse-interval modulation signal, and a microcomputer that is supplied with the start signal and the pulse-interval modulation signal and can supply the control pulse signal.

    Abstract: To provide a display device that is suitable for increasing in size. To provide a display device in which display unevenness is suppressed. To provide a display device that can display an image along a curved surface. The display device includes two display panels, two plates, two stages, two driver circuits, two adjusting units, and a frame. Each display panel includes a display portion, an operating circuit portion, a terminal, an external electrode, a transparent portion, and a first portion and has flexibility. Each transparent portion includes a region transmitting visible light. The display panels are fixed so that transparent portions and parts of the display portions extend beyond the plates. The display portion of one of the two display panels overlaps with the transparent portion of the other display panel.

    Abstract: A display panel includes a plurality of light-emitting elements. Light emitted from a first light-emitting element has a CIE 1931 chromaticity coordinate x of greater than 0.680 and less than or equal to 0.720 and a CIE 1931 chromaticity coordinate y of greater than or equal to 0.260 and less than or equal to 0.320. Light emitted from a second light-emitting element has a CIE 1931 chromaticity coordinate x of greater than or equal to 0.130 and less than or equal to 0.250 and a CIE 1931 chromaticity coordinate y of greater than 0.710 and less than or equal to 0.810. Light emitted from a third light-emitting element has a CIE 1931 chromaticity coordinate x of greater than or equal to 0.120 and less than or equal to 0.170 and a CIE 1931 chromaticity coordinate y of greater than or equal to 0.020 and less than 0.060.

    Abstract: To provide a light-emitting device whose amount of light can be adjusted, or the like. The amount of light emitted from the light-emitting device can be adjusted by controlling the magnitude of the constant current pulse by a control signal. Specifically, the light-emitting device includes a constant current supply configured to be supplied with a control signal and a control pulse signal and configured to supply a constant current pulse; a control device configured to supply the control signal; a driver circuit configured to supply the control pulse signal; and a light-emitting panel configured to be supplied with the constant current pulse. The control signal is a signal for controlling the magnitude of the constant current pulse. The light-emitting panel includes a light-emitting element. The current density of the light-emitting element is greater than or equal to 10 mA/cm2 and less than or equal to 1000 mA/cm2.
