DEVICE AND METHOD FOR PROCESSING SIGNAL OF ELECTRONIC PEN HAVING CHANGED RESONANT FREQUENCY
Document Type and Number:
WIPO Patent Application WO/2019/203425
Kind Code:
A1
Abstract:
An electronic device is disclosed. Other various embodiments understood through the specification are also possible. The electronic device comprises: a housing; a display panel which is positioned inside the housing, is viewed through the housing and can detect the input of a stylus pen; a control circuit for controlling the display panel; a communication module positioned inside the housing; a processor positioned inside the housing and operatively connected to the display panel and the communication module; and memory positioned inside the housing and operatively connected to the processor. When the memory is executed, the processor receives, from the stylus pen by means of the communication module, a first signal comprising information relating to one or more frequencies associated with a resonant circuit inside the stylus pen, and instructions for adjusting one or more parts of the control circuit are stored by means of at least a part of the information.
