Abstract: Provided is a highly reliable semiconductor device. The present invention relates to a shift register circuit including a plurality of stages of sequential circuits. An output signal of a sequential circuit is input to a sequential circuit in the subsequent stage. Before a sequential circuit outputs a signal and after the sequential circuit outputs the signal, the potential of a gate of a transistor included in the sequential circuit is changed in accordance with a clock signal so as to avoid voltage stress application between the gate and a source of the transistor for a long time. The shift register circuit can be applied to a scan line driver circuit of a display apparatus, for example.

Abstract: Display data of pixels is updated at different timings. A scan line is connected to a first pixel and a second pixel, a first wiring is connected to the first pixel, and a second wiring is connected to the second pixel. In a first period, a signal for selecting the first pixel and the second pixel is supplied to the scan line. Setting data for setting a state where the display data of the first pixel is updated is supplied to the first wiring, and setting data for setting a state where the display data of the second pixel is updated is supplied to the second wiring. In a second period, a signal for selecting the first pixel and the second pixel is supplied to the scan line. Setting data for setting a state where the display data of the first pixel is not updated is supplied to the first wiring, and the setting data for setting the state where the display data of the second pixel is updated is supplied to the second wiring.

Abstract: At least one power line is connected to a battery mounted at a vehicle. Plural ECUs are each connected to the at least one power line. A processor switches one ECU at a time of the plural ECUs from a second state to a first state by sending state switching signals to the plural ECUs. A power line to which plural ECUs are connected is a target power line. On the basis of current values of the target power line measured by a current measurement section when these plural ECUs are switched to the first state one at a time, the processor determines whether or not each ECU is in an abnormal condition.

Abstract: In a touch panel assembly, the thickness of a touch panel is successfully reduced by using a touch panel 10 provided with no reinforcement member. A housing frame 50 that supports the components of a front light unit 20 in an integral manner is provided with a touch panel positioning mechanism, and the touch panel 10 is fixed to the positioning mechanism, whereby the absence of a reinforcement member is duly compensated for, thus ensuring the strength of the touch panel 10. Deformation of the touch panel 10 that occurs when the touch panel 10 is pressed for operation can be attenuated by a transparent buffer member 5 disposed between the touch panel 10 and a light conductor plate 22. Therefore, the touch panel 10 deformed is prohibited from contacting and damaging the light conductor plate 22, thus preventing the light conductor plate 22 from deteriorating in its functional performance.
