<p>A method for detecting touch points of touch control device is disclosed. The touch control device comprises a first substrate (1) having a first conductive layer (10) and a second substrate (2) having a second conductive layer (21). The first and second conductive layers (21) are respectively connected to a control circuit (4) which is coupled to a microcontroller (5). The control circuit (4) performs driving on the first conductive layer (10) to generate a gradient potential, and performs scanning on the second conductive layer (21) to determine a first-axis coordinates. Then the control circuit (4) drives the second conductive layer (21) to generate a gradient potential, and performs scanning on the first conductive layer (10) to determine the second-axis coordinates.</p> |
