    摘要: A display device integrated with an input device comprises a display panel having picture elements being scanned line-at-a-time, a detector for detecting a voltage pulse applied on one of the picture elements through electrostatic coupling, a first circuit for applying a voltage pulse of a type differing with a plurality of regions into which the display panel are divided, on electrodes associated with the picture element in one of the plurality of regions during the non-display period, a second circuit for determining a region of the picture element by the type of the voltage pulse detected by the detector, a fourth circuit for determining a relative X coordinate in the determined region by counting clock pulses synchronized with sequential application of a voltage on electrodes until the fourth circuit receives the voltage pulse detected by the detector during the non-display period, and a fifth circuit for determining an absolute X-coordinate by the determined region and the relative X-coordinate.

    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.
