METHOD FOR SETTING MEASURING POINT COORDINATE POSITION FOR LINEARITY EVALUATION OF TOUCH PANEL, LINEARITY INSPECTION APPARATUS USING SETTING METHOD, AND TOUCH PANEL WITH LINEARITY EVALUATED BY SAME
METHOD FOR SETTING MEASURING POINT COORDINATE POSITION FOR LINEARITY EVALUATION OF TOUCH PANEL, LINEARITY INSPECTION APPARATUS USING SETTING METHOD, AND TOUCH PANEL WITH LINEARITY EVALUATED BY SAME
PROBLEM TO BE SOLVED: To provide a method for setting coordinate positions of voltage measuring points that increases the reliability of linearity evaluation.;SOLUTION: Coordinate positions of X-axis and Y-axis voltage measuring points P00, P01, etc. are set as follows. Position coordinate points Q1 and Q2, R1 and R2 enabling voltage measurement with given pressing force first are detected in two arbitrary points off the edge of one side 20a, 20b of X-axis/Y-axis outer sides of a touch panel. A straight line Q, R connecting the two position coordinate points Q1 and Q2, R1 and R2 is produced along the X-axis/Y-axis. The coordinate position of the intersection where the X-axis straight line Q and the Y-axis straight line R cross is defined as the origin O. Values such as an x-axis measuring point pitch and a Y-axis measuring point pitch are added to the origin O to set the coordinate positions of the voltage measuring points P00, P01, etc.;COPYRIGHT: (C)2005,JPO&NCIPI
