TOUCH SENSING APPARATUS

A touch sensing apparatus configured to receive an input signal of a stylus pen is provided. The touch sensing apparatus includes a display panel, a touch panel and a control circuit. The touch panel includes a substrate, a touch sensing element and a decorative element. The touch sensing element has a plurality of nodes for detecting the input signal. The control circuit is coupled to the display panel and the touch panel to activate a plurality of functions of the touch sensing apparatus through a plurality of determination steps, e.g., whether a capacitive sensing value of the node falls in a first threshold range, larger than a second threshold or larger than a third threshold, and whether the stylus pen touches the touch panel.
