摘要：
A method for detecting touch points of touch control device is disclosed. The touch control device comprises a first substrate having a first conductive layer and a second substrate having a second conductive layer. The first and second conductive layers are respectively connected to a control circuit which is coupled to a microcontroller. The control circuit performs driving on the first conductive layer to generate a gradient potential, and performs scanning on the second conductive layer to determine a first-axis coordinates. Then the control circuit drives the second conductive layer to generate a gradient potential, and performs scanning on the first conductive layer to determine the second-axis coordinates.
