Patent abstract
The present invention provides a capacitive sensing detection method for an active pixel matrix. The method comprises to select a first sensing region in the active pixel matrix. Then, a first signal is transferred to the first sensing region. Next, a second sensing region is selected. A second signal is transferred to the second sensing region for sensing. Finally, a change of the first signal and the second signal is detected and calculated to determine a position.
