Abstract:
A stylus (100), a touch panel (200), a display device and a touch sensing method are provided. The stylus (100) includes: a first emitting electrode (12); a second emitting electrode (13), wherein a distance between the first emitting electrode (12) and the second emitting electrode (13) in an extension direction of the stylus (100) is greater than zero; and an emitting circuit (11), which is connected to the first emitting electrode (12) and the second emitting electrode (13), respectively. The emitting circuit (11) is used to emit a first electrical signal outwards through the first emitting electrode (12) and to emit a second electrical signal outwards through the second emitting electrode (13), so that the touch panel (200) determines a tilt angle (A1) of the stylus (100) relative to the touch panel (200) according to the received first and second electrical signals.
