发明名称 CALIBRATION SYSTEM FOR ANALOG TOUCH PANEL
摘要 <p>PURPOSE:To eliminate the need for troublesome periodic calibration by dynamically performing calibration when the touch panel is actually used. CONSTITUTION:The frequency of depression of the touch panel P is accumulated and stored and when the accumulated and stored value reaches a decision value during the actual use of the touch panel, the position of the touch panel P is automatically corrected. Further, the frequency of depression of the touch panel P is accumulated and stored in a storage device 7 and when the accumulated frequency reaches a specific value, the position is automatically corrected. Further, a calibration device is provided, the frequency of depression of the analog touch panel P is stored, and when the accumulated frequency reaches the specific value, the position is automatically corrected. Thus, the calibration is dynamically performed during the actual use of the touch panel P to eliminate the need for the troublesome periodic calibration and the touch panel P which is calibrated with high precision can be used.</p>
