Patent ID: 8872774

Claim:
A method for correcting initial touch points on a touch panel, the touch panel comprising a plurality of sensors, wherein each sensor detects a touch point on the touch panel, the method comprising: classifying the plurality of sensors into a plurality of first sensing groups assigned sequential serial numbers; dividing a plurality of sensors of each first sensing group into a plurality of second sensing groups assigned sequential serial numbers, wherein each second sensing group comprises a same number of the sensors assigned sequential serial numbers; detecting initial touch points on the touch panel; configuring a plurality of headers corresponding to the plurality of first sensing groups; configuring a plurality of data structures corresponding to a header which corresponds to a first sensing group that has detected the initial touch points, each of the plurality of data structures corresponding to a sensor that has detected an initial touch point in the first sensing group, and each of the plurality of data structures recording a serial number of a corresponding second sensing group in the first sensing group and a sensor serial number of a sensor of the corresponding second sensing group; loading the plurality of headers and the plurality of data structures corresponding to each of the plurality of headers for determining a plurality of initial touch points on the touch panel; and filtering out the plurality of initial touch points from a plurality of detected touch points on the touch panel, wherein each of the plurality of headers records a number of second sensing groups that have detected the initial touch points in a corresponding first sensing group, and a tag indicating whether the corresponding first sensing group has detected the initial touch points.
