Abstract: Discussed is a touch display device and a touch sensing method. More particularly, according to the number of pens that have been paired, the frame can be reconfigured by changing the type of all or part of the multiple touch time periods in the frame, and it is possible to provide high-speed pen search and pen pairing by designing a highly scalable pen protocol to flexibly change the pen mode.
