    Abstract: A source line through which a video signal is transmitted also serves as a driving electrode of a touch sensor. To perform display, a video signal is transmitted to the source line. To sense the touch, a driving signal is transmitted to the source line. A circuit for transmitting the video signal and the driving signal to the source line has a structure in which a period for transmitting the driving signal is added in the wiring through which the digital video signal is transmitted and the output to the source line is switched by using a switching circuit. Alternatively, the circuit has a structure in which a period for transmitting the driving signal is added in a wiring through which a latch signal is transmitted and the output to the source line is switched.

    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.
