摘要: Detect four sets of first touch coordinates (A, B, C, D) on a touch panel. Divide an area delimited by the detected four sets into two areas of triangles (ABD, BCD). For each area of triangle, obtain a first correction factor. Detect a set of second touch coordinates (P, Q) selected within a respective one of the areas of triangles. Convert the detected set of second touch coordinates into a set of first corrected coordinates. Detect a difference between the set of first corrected coordinates and a set of true display coordinates. Where the detected difference is greater than a predetermined threshold value, further divide the area of triangle (BCD) into three areas of triangles (QBD, QBC, QCD). Obtain a second correction factor using the set of second touch coordinates and the sets of first touch coordinates corresponding to the vertices.
