发明名称 Display device
摘要 A display device is driven through no wire cable such as an FPC, and a display image is continuously held for a certain period of time by storing an image signal received from a wireless communication device so that the display image can be held even when the display device is out of communication range with the wireless communication device. A display device includes at least a pixel circuit having an SRAM (static random access memory) circuit, a circuit which controls the pixel circuit, an antenna circuit, a circuit which generates a demodulation signal, a circuit which rectifies a wireless signal, a circuit which generates first voltage, a charge circuit which stores second voltage, a charge control circuit, a voltage supply control circuit, and a circuit which controls the charge control circuit and the voltage supply control circuit.
