Problems solved by technology

However, when the stylus is tilted on the touch panel, the tip of the stylus is often not aligned with the pointer (or cursor) on the touch panel, that is, the position of the pointer (or cursor) displayed on the touch panel is in line with the touch panel. There is a drop in the position where the control pen wants to click and control, causing the user to click on the wrong position on the touch panel, resulting in inconvenient operation for the user

Abstract

The invention discloses a calibration method for an active capacitive touch-control pen. The calibration method for the active capacitive touch-control pen comprises the steps that at least one signal is generated by an induction coil of the active capacitive touch-control pen, and the at least one signal is transmitted to touch control input equipment by a nib or the induction coil of the active capacitive touch-control pen, so the touch control input equipment can be triggered; and an induction loop in the touch control input equipment synchronously receives the at least one signal set by the nib and induction coil of the active capacitive touch-control pen; according to a waveform of the signal, the touch control input equipment judges whether the active capacitive touch-control pen is inclined relative to the touch control input equipment; and according to the waveform of the signal, the touch control input equipment can calibrate a pointed position.

Description

technical field [0001] The invention relates to a touch pen, in particular to an active capacitive touch pen calibration method. Background technique [0002] With the development of science and technology, 3C products are introduced faster and faster, especially the touch operation interface has become the trend and mainstream of future development. [0003] The touch operation interface is mainly realized through the touch panel combined with the graphical operation interface of the operating system (operation system). The touch panel can be divided into resistive touch panel, capacitive touch panel, and optical touch panel according to its sensing principle. panel, electromagnetic touch panel and ultrasonic touch panel, etc. [0004] The above-mentioned touch panel is used to detect the position of the stylus to generate a corresponding pointer (or cursor) to interact with the corresponding computer device. However, when the stylus is tilted on the touch panel, the tip ...
