Knob device applicable to touch panel

The invention discloses a knob device applicable to a touch panel, the knob device comprises a knob cover, a plurality of sensing pads and a rotary sensing element, the plurality of sensing pads are fixedly arranged on the touch panel, a gap is formed between two of the sensing pads, and the rotary sensing element is arranged on the knob cover. The plurality of sensing pads and the plurality of gaps are distributed in an annular area around the center of an orthographic projection of the knob cover, the rotary sensing element is connected to the knob cover, and when the knob cover is rotated, the rotary sensing element rotates synchronously, so that the knob cover can rotate synchronously. When a contact and rotation event occurs in the knob device and the rotation sensing element overlaps with one of the plurality of sensing pads, the position of the rotation sensing element controls a rotation sensing signal of the touch panel. 本发明公开一种可应用于一触控面板的旋钮装置，该旋钮装置包含一旋钮盖、多个感测垫以及一旋转感测元件，该多个感测垫固定地设置于该触控面板上，其中两个感测垫之间形成有
