Abstract
The present disclosure relates to a touch panel technology, and especially to an edge grip detection method of a touch panel and a device using the same. The edge grip detection method comprises: determining whether an edge area state has changed; eliminating a first edge signal when the edge area state does not change; and updating the first edge signal as next standard signal when the edge area state changes. The edge grip detection method and an edge grip detecting device of the touch panel opportunely detect and dynamically update state and data of the edge area, thereby eliminating edge grip signals from touch signals of the touch panel to obtain normal touch signals. Thus, impact on the normal operation of the touch panel by edge grips is reduced.
