    摘要： An information processing system includes a bus; a display data generating circuit coupled to the bus for generating display data in a form of a plurality of bits for each of a plurality of pixels of a display panel; and a display apparatus coupled to the bus. The display data generating circuit includes a central processing unit and a memory. The display apparatus includes a display panel including a plurality of data lines and a plurality of scanning lines in a matrix form with pixels formed at intersections of the data lines and the scanning lines, the display panel being capable of displaying a grayscale image in accordance with the display data in a form of a plurality of bits for each of a plurality of pixels of a display panel; a signal driver for supplying driving voltages corresponding to the display data to at least a part of the plurality of data lines to display an image, the signal driver including a display memory for storing the display data and being constructed in an integrated circuit; and a scanning driver for scanning the plurality of scanning lines. The display data generating circuit transfers the display data via the bus to the display memory.

    摘要： A display unit which can detect the X coordinate of a position with which a pen is in contact more efficiently. In a non-display period, X-electrodes are grouped into N regions according to the X-electrode arrangement, each region is divided into two parts according to the X-electrode arrangement, and selection voltage is applied to the X-electrodes belonging to each part having larger X coordinates. The process is repeated in order while N is doubled from one to the half value of the number of the X-electrodes of a liquid crystal panel. If a pen coming in contact with the liquid crystal panel and detecting X-electrode selection voltage detects selection voltage with respect to each N value, the Nth most significant bit of the X coordinate of the position with which the pen is in contact is set to `1.` If the pen does not detect selection voltage, the bit is set to `0.` Thus, the X-electrode of the position with which the pen is in contact can be detected at the number of selection voltage application times equal to the minimum number of bits that can represent each of the X-electrodes.
