摘要： A highly reliable light-emitting device is provided. A lighting device or a display device with a high level of safety and without an exposed electrode is provided. A lighting device or a display device with high layout flexibility is provided. A light-emitting system or a display system to which the light-emitting device or the display device can be applied is provided. An electrode for receiving power and a rectifier circuit are provided in a light-emitting device including an organic EL element and arranged so as to face an electrode for transmitting power, whereby alternating-current power is supplied to the light-emitting device. The alternating-current power is rectified by the rectifier circuit to direct-current power so that the organic EL element in the light-emitting device is driven.

摘要： An object of the invention is to reduce the power consumption of a semiconductor device that requires a plurality of reference potentials and a method of driving the semiconductor device. Disclosed is a semiconductor device having a potential divider circuit in which a potential supplied to a power supply line is resistively divided by resistors connected in series to the power supply line so that a desired potential is output through a switch transistor electrically connected to the power supply line. A drain terminal of the switch transistor is electrically connected to a gate terminal of a transistor provided in a circuit on the output side (or to one terminal of a capacitor) to form a node. The switch transistor has an off current low enough to hold the desired voltage in the node even when the potential is no more supplied to the power supply line.

摘要： An object is to provide a power feeding system and a power feeding method which are more convenient for a power feeding user at the power receiving end, without causing increases in complexity and size of devices. An object is to provide a power feeding system and a power feeding method which also allow a power feeding provider (a company) which feeds power (at the power transmitting end) to supply power without waste. A power feeding device which wirelessly supplies power to a power receiver detects the position and the resonant frequency of the power receiver by receiving a position and resonant frequency detection signal using a plurality of sub-carriers having different frequencies from the power receiver, and controls the frequency of a power signal to be transmitted to the power receiver on the basis of the information. An efficient power feeding service can be offered by transmitting a power signal to the power receiver at an optimum frequency for high power transmission efficiency.

摘要： When a portable electronic appliance is provided with two systems, a wireless power-feeding system and a wireless communication system, each system requires two power-receiving devices, a coil and an antenna, leading to a problem of increased electronic appliance size and cost. Wireless power feeding employs the resonance method and uses a resonance coil using the resonance method and a power-receiving coil that receives power from the resonance coil. At least one of the resonance coil and the power-receiving coil can also be used as an antenna for wireless communication. Thus, a power-receiving device that can be used for two systems, wireless power feeding and wireless communication, can be provided.

摘要： In a rectifier circuit, by using a transistor whose off-state current is small as a so-called diode-connected MOS transistor included in the rectifier circuit, breakdown which is caused when a reverse bias is applied is prevented. Thus, an object is to provide a rectifier circuit whose reliability is increased and rectification efficiency is improved. A gate and a drain of a transistor are both connected to a terminal of the rectifier circuit to which an AC signal is input. In the transistor, an oxide semiconductor is used for a channel formation region and the off-state current at room temperature is less than or equal to 10−20 A/μm, which is equal to 10 zA/μm (z: zepto), when the source-drain voltage is 3.1 V.
