    Abstract: A display device which exhibits light with high color purity is provided. A display device with low power consumption is provided. An embodiment is a display device which includes a first pixel electrode, a second pixel electrode, a light-emitting layer, a common electrode, a first protective layer, and a semi-transmissive layer. The light-emitting layer includes a first region positioned over the first pixel electrode and a second region positioned over the second pixel electrode. The common electrode is positioned over the light-emitting layer. The first protective layer is positioned over the common electrode. The semi-transmissive layer is positioned over the first protective layer. Reflectivity with respect to visible light of the semi-transmissive layer is higher than reflectivity with respect to visible light of the common electrode. The semi-transmissive layer does not overlap with the first region and overlaps with the second region. For example, the semi-transmissive layer may include an opening in a position overlapping with the first region.

    Abstract: A low-power display device in which an operation method is optimized in accordance with the resolution and the frame frequency of a content is provided.
    The display device includes a display unit and an image receiving apparatus. In the case where the resolution of a content is lower than the resolution that can be displayed by the display device, a source driver and a gate driver included in the display unit output signals to a plurality of source lines and gate lines, and the source driver and the gate driver are operated at lower operation frequencies. Furthermore, the power supply voltages of the logic circuit portions included in the source driver and the gate driver are lowered. In the case where the frame frequency of the content is lower than the frame frequency that can be displayed by the display device, the source driver and the gate driver included in the display unit are operated at lower operation frequencies, and power supply voltages of the logic circuit portions included in the source driver and the gate driver are lowered. The image receiving apparatus detects the resolution and the frame frequency of the content.

    Abstract: A battery module with high impact resistance is provided. A battery module using an elastic body such as rubber for its exterior body covering a battery is provided. A bendable battery module is provided. As the exterior body covering a battery, an elastic body such as rubber is used, and the exterior body is molded in two steps. First, a first portion provided with a depression in which a battery is stored is molded using a first mold. Next, a battery is inserted into the first portion. Subsequently, second molding is performed using a second mold so as to fill an opening of the depression in the first portion, so that a second portion is formed. The second portion serves as a cover for closing the opening of the depression in the first portion. The second portion is formed in contact with part of the electrodes in the battery and part of an end portion of the second exterior body in the battery.

    Abstract: A device capable of being used for a long time is achieved. A power supply, a connection method of a power supply, or a connecting member, for easy attachment and detachment and non-detachment when in use, is provided. A power supply, a connection method of a power supply, or a connecting member for easy replacement is provided. A highly designed power supply is provided. Power from a battery is supplied to an electronic device through a connecting member including a pipe, a spring, and a pair of pivots. The pair of pivots are electrically insulated from each other, and electrically connected to any one of a pair of electrodes of the battery. The electronic device into which the pair of pivots are inserted includes a pair of bearings capable of receiving power.
