摘要： PURPOSE:To reduce the price of a liquid crystal display system by providing a data driver which outputs a voltage corresponding to display data and a scanning driver which outputs a scanning signal making the scanning line constituting a selected line effective. CONSTITUTION:Latches 204-206 of R, G, and B provided in the data driver 108 fetch only R, G, and B data out of the displayed data by the data driver 108 as many as for data signal lines 109. A liquid crystal driving voltage generating circuit shares the conversion of the R, G, and B data, and converts display data of the data signal lines 109 that the data driver 108 has into a liquid crystal driving voltage at the same time and outputs it to the data signal lines 109. The scanning driver 111 divides a period of one line into three, generates an R, a G, and a B scanning signal each shifted a 1/3-line period, and displays an R, a G, and a B display line constituting one dot of a liquid crystal panel 112 in order in the one-line period. Therefore, an inexpensive liquid crystal controller which does not have an R, a G, and a B line memory is usable.

摘要： A system for providing a service through a non-contact communication unit such as a wireless communication unit is disclosed. Specifically, an electronic ticket is communicated between a so-called mobile terminal and the non-contact communication unit equipped in a ticket examiner. The ticket examiner comprises a stocker for storing magnetized slips, roll paper or plastic slips, and a shaper for cutting the magnetized slip or the roll paper into a proper size. The ticket examiner confirms the validity of the electronic ticket for issuing a ticket.

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.
