Abstract: To achieve versatility, a driver IC has a function of generating an analog data signal from an image signal input from the outside; a function of outputting the analog data signal from an output pin; and a function of setting the analog data signal as a data signal for alternating-current driving or for direct-current driving, in accordance with data of a digital signal input from the outside. For example, the driver IC can output data signals for alternating-current driving from output pins in odd-numbered columns and data signals for direct-current driving from output pins in even-numbered columns. Furthermore, the driver IC can output data signals for alternating-current driving or for direct-current driving from all the output pins. The driver IC can drive a liquid crystal panel, a self-luminous panel, and a hybrid display panel where one subpixel includes a liquid crystal element and a light-emitting element.

Abstract: A circuit capable of keeping input impedance constant is provided. Further, a circuit which can contribute to improvement in power feeding efficiency in power feeding by a magnetic resonance method is provided. A voltage (a former voltage) proportional to a direct-current voltage input to a DC-DC converter from the outside and a voltage (a latter voltage) proportional to a current input from the outside are detected, and the ratio of the former voltage and the latter voltage are held constant. Accordingly, input impedance can be kept constant. Further, impedance conversion is performed in the DC-DC converter. Thus, even when the battery in which power feeding is performed exists on an output side of the DC-DC converter, input impedance can be kept constant. Consequently, power can be supplied to a power receiving device including the DC-DC converter and the battery with high power feeding efficiency by a magnetic resonance method.

Abstract: A semiconductor device in which an increase in the degree of wiring congestion due to an increase in the number of output terminals of a driver IC can be reduced is provided. In a shift register of the driver IC, pulse signals are sequentially output in different directions. For example, pulse signal output circuits are provided so as to sequentially output pulse signals in ascending order from right to left and then sequentially output pulse signals in ascending order from left to right. With such a structure, output signals of the driver IC can be output not only from a side opposite to a side along which an input terminal is provided, but also from a side along which the input terminal is provided; thus, the number of output terminals can be increased without an increase in the degree of wiring congestion.

Abstract: Electric charge is stored, in accordance with a bias voltage, in a gate of a transistor performing switching operation between an input terminal and an output terminal, and the gate is brought into an electrically floating state at the time of completing the storage of electric charge in the gate. One electrode of a capacitor is connected to the gate in an electrically floating state, and the potential of the other electrode of the capacitor is increased, so that the voltage of the gate is increased using capacitive coupling. The potential of the gate of the transistor is increased, and the bias voltage is sampled without being decreased. Each of the transistor performing switching operation and a transistor connected to the gate of the transistor is a transistor with an extremely low off-state current.

Abstract: A semiconductor device with a novel structure. An upper-bit grayscale voltage and a lower-bit grayscale voltage are separately produced, and then the grayscale voltages are converted into currents and the currents are synthesized. The obtained current is converted into a voltage, and thus an intended grayscale voltage is obtained. The upper-bit grayscale voltage and the lower-bit grayscale voltage are generated using respective D/A converter circuits each including a resistor string circuit and a pass transistor logic. The increase in the number of transistors supplied with high voltage, which occurs along with the increase in the number of digital signal bits, is prevented. Thus, the increase in parasitic capacitance can be suppressed, and a smaller circuit area and higher response speed are obtained.
