Abstract: A method, a device, and a non-transitory storage medium having instructions to receive a touch event originating from a touch panel; compare a timing of the touch event and a timing of a display refresh event; determine whether to adjust a time during which a next scan of the touch panel occurs based on a comparison of the timing of the touch event and the timing of the display refresh event; calculate a time value that indicates when the next scan occurs based on a determination to adjust the time; and adjust the time during which the next scan occurs based on the time value.

Abstract: The disclosure relates to the technical field of capacitive touch panels and discloses a touchpen which may be used in mobile phones, computers and other devices with touch panels for writing characters, letters and other symbols. In particular it relates to a capacitive touchpen 10 for inputting information into an electronic device 1 through touching of a capacitive touch panel 30, the capacitive pen comprising an elongated body member 11 comprising a conductive part 13 and a tip 12 disposed at one end of the body member 11 having a contact surface 14 for contacting the capacitive touch panel 30. The conductive part 13 is configured such that the distortion of the touch panel's electrostatic field caused by the conductive part 13 when changing the position of the touchpen 10 in relation to the capacitive touch panel 30, when the contact surface is kept in contact with the touch panel 30, is sufficient to register a change in capacitance by the capacitive touch panel 30. The disclosure further relates to methods for detecting the position of a touch pen as well as to an electronic device and a computer program.
