摘要： When the excitation frequency of a touch panel and the frequency of external noise match or are close, noise cannot be removed by a bandpass filter. In addition, when a touch detection operating period is limited to a short period such as the no addressing period, the signal-to-noise ratio (S/N) decreases because frequency separation decreases and the noise removal effect by averaging is degraded. An electronic device of the present invention includes a sensor system (101), an excitation generator (102) that generates an intermittent sinusoidal signal and applies this signal to the sensor system, and a demodulator (105) that demodulates the amplitude modulated signal that is the output of the sensor system. The demodulator uses both the response x1(t) of the sensor system in the period in which the excitation generator outputs the sinusoidal signal, and the response z1(t) of the sensor system in the period in which the excitation generator does not output the sinusoidal signal at least either immediately before or immediately after the signal output to generate the demodulated signal D(t).

摘要： A bidirectional scanning circuit for a peripheral driving circuit for a liquid crystal display, a contact-type image sensor, a liquid crystal shutter, a vacuum fluorescent display or the like is improved in operation speed and yield in production. In the scanning circuit, a data signal is successively delayed and transferred to produce scanning pulse signals to be outputted. The scanning circuit comprises a plurality of switching transistors connected in cascade connection such that each switching transistor receives a data signal outputted from a preceding switching transistor and passes the data signal so as to be applied to a following switching transistor in response to a pair of clock signals, a plurality of feedback circuits each for receiving a signal outputted from a corresponding switching transistor in response to a further pair of clock signals and compensating for a drop of the signal level of the thus received signal, and a plurality of buffer circuits for individually receiving signals successively outputted from the feedback circuits and individually outputting the received signals as scanning pulse signals.

摘要： A scanning circuit according to the invention has a form of integrated thin film transistors on a substrate, comprising a multiplicity of serially interconnected stages of pass transistors or clocked inverters for successive transmission of a signal with a predetermined delay. Each stage includes only one pass transistor or clocked inverter which is operated by a pair of mutually inverted clock puls. Each stage also comprises an output buffer circuit for providing a scanning signal having a frequency twice as large as said clock pulses by receiving the output of the corresponding pass transistor or clocked inverter via an NOR gate which is operated by one of tile paired clock pulses. The scanning circuit is thus capable of doubly fast scanning of a display, e.g. a high resolution display. The scanning circuit is simple in structure, so that it occupies only a small area on a substrate and gives high yield and reliability.
