Abstract
The present disclosure relates to a touch panel controller, a control information acquisition method and a touch display device in the field of display technology. The touch panel controller includes at least two conductive members and a rotating component. The rotating component includes a supporting component and a mounting component connected to each other. The mounting component is configured to have the at least two conductive members mounted thereon. One end of the supporting component is configured to determine a placement surface that is in contact with a touch panel. A distance between each of the at least two conductive members and the placement surface is less than a sensing distance, and the sensing distance is a distance at which a capacitance change caused by the conductive member is detectable by the touch panel. In the present disclosure, a plurality of rotatable conductive members in the controller are used to input a multi-point touch operation such as rotation or multi-point sliding, which solves the problem in the related art that it is difficult for the stylus to accomplish multi-point touch operations and achieves an effect of performing a variety of multi-point touch operations through the controller.
