Method for correcting and recording initial touch points on touch panel

摘要

While correcting and recording initial touch points on a touch panel, a plurality of sensors on the touch panel are classified into a plurality of first sensing groups assigned with serial numbers, and a plurality of sensors of each the first sensing group are equally divided into a plurality of second sensing groups assigned with serial numbers. After detecting initial touch points on the touch panel, a plurality of headers are generated for the plurality of first sensing groups, and a data structure is generated for each of the sensors having detected initial touch points according to whether first sensing groups corresponding to the headers have the sensors having the detected initial touch points or not. At last, the initial touch points are filtered off from a plurality of detected touch points on the touch panel, according to initial touch point information recorded in loaded data structures.

1. 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.
