    摘要： A personal portable computer system includes peripheral devices such as a printer and a CRT which can be driven by a battery power source. The computer system includes a computer body which contains interface units and power supplied to the interface units is controlled. The interface units are used for supplying power to the peripheral devices.

    摘要： A display apparatus of a simple matrix type displays an intermediate tone on a liquid panel by a data thinning-out system. As a modulated alternating inverted signal for determining a polarity of a driving voltage is applied to each pixel of the liquid panel, employed is a signal whose phase is inverted by 180.degree. every tone representing cycle which is a predetermined period of a plurality of frames, and it is structured such that a polarity of the driving voltage to be applied to each pixel is changed according to polarity of the modulated alternating inverted signal. Therefore, a positive polarity portion and a negative polarity portion of an effective voltage to be applied to a pixel in an arbitrary tone representing cycle are completely canceled by a negative polarity portion and a positive polarity portion of the driving voltage to be applied to the pixel in a tone representing cycle adjacent to said arbitrary tone representing cycle respectively. As a result, each of mean values of effective voltages applied to respective pixels in the two adjacent tone representing cycles becomes zero, so that no direct voltage is applied to the liquid crystal panel.
