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.
摘要翻译：可以更有效地检测笔的位置的X坐标的显示单元。在非显示期间，根据X电极配置将X电极分组为N个区域，根据X电极配置，将各区域分为两部分，并且将选择电压施加到属于每个部分具有较大的X坐标。该过程按顺序重复，而N从液晶面板的X电极的数量的一个值的1/2值翻倍。如果与液晶面板接触并检测X电极选择电压的笔相对于每个N值检测选择电压，则将与笔接触的位置的X坐标的第N个最高有效位设置为 '1' 如果笔不检测选择电压，则该位设置为“0”。因此，可以以等于可以表示每个X电极的最小位数的选择电压施加时间的数量来检测与笔接触的位置的X电极。
