TOUCH RECOGNITION METHOD AND TOUCH PANEL THEREOF

摘要

A method for identifying a contact with a touch panel includes: performing a first measuring process for obtaining a baseline signal; performing a second measuring process for obtaining a contact signal if there are any contacts or approaches of the touch panel with objects; comparing the values of the baseline signal with the contact signal for generating the contact signal with a location information; performing a third measuring process for installing an exclusion area according to the baseline signal; determining whether the location information is in the exclusion area; and, discarding the location information if the location information is in the exclusion area.

1. A touch recognition method for a touch panel, the touch panel including a plurality of driving electrodes and a plurality of sensing electrodes, the method comprising:
initializing the driving electrodes and the sensing electrodes, including setting the driving electrodes and the sensing electrodes to a state of Low electric potential; charging the driving electrodes to a state of High electric potential; switching the sensing electrodes to a floating state, during when the sensing electrodes are charged for a short period with an integrated circuit including an analog-to-digital converter; stopping the charge of the sensing electrodes, and switching the driving electrodes from the state of High electric potential to the state of Low electric potential, while the senor electrodes are kept on the floating state; and generating a plurality of sensing signals on the sensing electrodes sequentially measured by the analog-to-digital converter.
