Abstract
A touch control detecting apparatus and method are provided. The touch control detecting method is adapted for a touch panel which has a plurality of touch rows and touch columns. The touch control detecting method includes: executing a mutual capacitor touch detection and a self-capacitor touch detection on the touch panel simultaneously, and obtaining a mutual capacitor touch detecting result and a self-capacitor touch detecting result respectively; and then executing an operation on the mutual capacitor touch detecting result and the self-capacitor touch detecting result to obtain position information of at least one touch point on the touch panel.
Claims14
A touch control detecting method, adapted for a touch panel which has a plurality of touch rows and touch columns, comprising:
- executing a mutual capacitor touch detection and a self-capacitor touch detection on the touch panel simultaneously and obtaining a mutual capacitor touch detecting result and a self-capacitor touch detecting result respectively;
- and
- executing an operation on the mutual capacitor touch detecting result and the self-capacitor touch detecting result to obtain position information of at least one touch point on the touch panel.
A touch control detecting apparatus, comprising:
- a touch panel, having a plurality of touch rows and touch columns;
- and
- a touch detecting controller, coupled to the touch rows and the touch columns, wherein the touch detecting controller executes a mutual capacitor touch detection and a self-capacitor touch detection simultaneously on the touch panel to obtain a mutual capacitor detecting result and a self-capacitor detecting result, and executes an operation on the mutual capacitor detecting result and the self-capacitor detecting result to obtain position information of at least one touch point on the touch panel.
