Description
GT9147 adopts the latest capacitance detection technology and built-in high-performance micro-signal detection circuit, which can solve LCD interference and common mode interference problems well. In terms of software algorithm, it is specially designed based on the electrical environment of single-layer mutual capacitance, which can support 5-point touch. At the same time supports HotKnot function GT9147 can identify the real-time accurate position, movement track and touch area of 5 touch points at the same time. And according to the needs of the main control, the touch information of the corresponding points can be read.
