1. A correction apparatus for a self-capacitive touch panel, the touch panel comprising a plurality of upper electrodes and a plurality of lower electrodes, the plurality of lower electrodes and upper electrodes being in a staggered arrangement along a first reference direction, the correction apparatus comprising:
an initial coordinate calculation module, configured to calculate a first initial coordinate in the first reference direction and a second initial coordinate in a second reference direction of a touch position according to at least one sensing result associated with the upper electrodes and at least sensing result associated with the lower electrodes, respectively, the second reference direction being substantially perpendicular to the first reference direction; a correction parameter calculation module, configured to calculate a first correction parameter according to the at least one sensing result associated with the lower electrodes, and to calculate a second correction parameter according to the at least one sensing result associated with the upper electrodes; a compensation calculation module, configured to calculate a compensation amount according to the first correction parameter, the second correction parameter and the first initial coordinate; and a correction module, configured to correct the second initial coordinate according to the compensation amount. |
