Embodiment Construction
[0035] A specific embodiment of the present invention is a device for eliminating coupling capacitance. In this embodiment, the device for eliminating coupling capacitance is applied to a capacitive touch panel of a touch display device, and the capacitive touch panel includes a plurality of touch pads. The touch display device can sense the position of at least one touch point formed by any object on the capacitive touch panel. In fact, there is no specific limitation on the object forming the at least one touch point on the capacitive touch panel. Generally speaking, it can be a user's finger or a stylus tip, but not limited thereto.
[0036] see image 3 , image 3 A functional block diagram of the device for eliminating coupling capacitance applied to a capacitive touch panel of this embodiment is shown. Such as image 3 As shown, the coupling capacitance elimination device 3 includes a touch sensing module 30 , a coupling capacitance elimination module 32 and a coordina...
