摘要： In order to sufficiently save the power consumption and to lower the withstand voltage of elements, by having one data signal line per one row of pixels and one scanning signal line per one line of pixels, the polarity of data written in the data signal line is varied each one field period. The power source magnitude of the scanning signal lines to be written is further varied each one field period. Specifically, on opposing sides of the pixel array, data signal line driving circuits are provided. The data signal line driving circuits supply voltages of different magnitude and polarity. Adjoining pairs of data signal lines are connected to each of the data signal line driving circuits with analog switches. In a certain display period, such as every field period, the analog switches each select one of a pair of adjacent data signal lines. In the next display period, the reverse selection is made. This suppresses the charge and discharge current of the data signal lines, and thus the operating voltages of the data signal line driving circuits may be lowered. As a result, the power consumption of the image display device may be saved, and the withstand voltage of the constituent elements can be lowered. Thus, manufacturing cost and operating cost can be reduced.

摘要： In a semiconductor device wherein an active device circuit and electrically conductive lines, such as a power source line for supplying power to the semiconductor active device circuit or signal lines for inputting a signal to the semiconductor active device circuit, are formed together on a single substrate, an improved arrangement wherein a conventional power source or signal line is formed by using a plurally of individual lines of substantially uniform electrical resistance where the electrical resistance of each line is limited to a predetermined value. Moreover, a waveform deterioration response signal component is added to a signal transmitted through the signal lines so as to improve the transmitted signal by compensating for waveform deterioration experienced during circuit operation. In addition, an electrical capacity forming electrode is provided alongside substantial length of the power source line. A capacitor is thus effectively formed within the active device circuit by intervening a dielectric between the power source line and the capacity forming electrode so as to reduce high-frequency noise which occurs in the power source line. The disclosed arrangements substantially reduce the occurrence of an irregular operation in the active device circuit.
