Abstract

A touch panel correcting apparatus for correcting a first coordinate and a second coordinate associated with a touch position is provided. The correcting apparatus includes a memory and a controller. The memory stores a look-up table storing a plurality of corrected coordinates. The controller selects a corrected first coordinate from the look-up table according to the first coordinate, and substitutes the corrected first coordinate and the second substitute into a function to generate a corrected second coordinate corresponding to the second coordinate.
