The structure of the device is improved.

The main purpose of the present invention is that the main touch unit is provided with a clock pin and a plurality of data pins for electrically connecting to the plurality of sub-touch units through the same line through the clock pin. The cost of the circuit is configured to be electrically connected to the plurality of sub-touch units through the plurality of data pins, so that the main touch unit can simultaneously obtain the scan data of the plurality of sub-touch units in a certain period of time. In order to improve the execution speed of the touch control unit, the main touch unit can reduce the manufacturing cost and improve the operation efficiency, thereby improving the applicability of the product.
