摘要： A semiconductor device such as an RFID, which can easily generate a given stable potential, is provided. Circuits included in a semiconductor device are categorized depending on whether a given stable power source potential is necessary. A power source potential generated from a wireless signal received by an antenna with the use of the antenna and a rectifier circuit is supplied to a circuit which needs a given stable power source potential through a regulator. On the other hand, a power source potential generated by the rectifier circuit is supplied to a circuit other than the circuit which needs the arbitrary power source potential. Thus, a semiconductor device including a regulator circuit easily designed with a smaller layout can be provided, and the semiconductor device can easily generate a given stable power source potential.

摘要： In a case where an ASK method is used for a communication method between a semiconductor device and a reader/writer, the amplitude of a radio signal is changed by data transmitted from the semiconductor device to the reader/writer when data is not transmitted from the reader/writer to the semiconductor device. Therefore, in some cases, the semiconductor device mistakes data transmitted from the semiconductor device itself for data transmitted from the reader/writer to the semiconductor device. The semiconductor device includes an antenna circuit, a transmission circuit, a reception circuit, and an arithmetic processing circuit. The antenna circuit transmits and receives a radio signal. The transmission circuit outputs to the reception circuit a signal showing whether or not the antenna circuit is transmitting the radio signal.

摘要： A semiconductor device with high definition, which includes a plurality of sets each including a photosensor and a display element including a light-emitting element arranged in a matrix is provided, wherein a power supply line electrically connected to the display element also serves as a power supply line electrically connected to the photosensor.

The stability of the potential of the power supply line leads to the stability of the driving voltage of the display element and the stability of the driving voltage of the photosensor. Accordingly, the semiconductor device with high definition, high display quality, and high accuracy of imaging or detection of an object can be provided.

摘要： In a field-sequential liquid crystal display device, image quality and detection accuracy in image capture are improved by increasing the frequency of input of image signals and securing a sufficient imaging period. Image signals are concurrently supplied to pixels provided in a plurality of rows among pixels arranged in matrix. Further, image capture is concurrently performed in pixels provided in a plurality of rows among pixels arranged in matrix. Thus, the frequency of input of an image signal to each pixel of the liquid crystal display device can be increased and a sufficient imaging period can be secured. As a result, in the liquid crystal display device, display deterioration such as color break which is caused in a field-sequential liquid crystal display device can be suppressed and improvements in image quality and detection accuracy in image capture can be realized.
