An active control method of a capacitive touch control pen and an active type capacitive touch control pen

Abstract

The invention relates to an active control method of a capacitive touch control pen and an active type capacitive touch control pen. The active type capacitive touch control pen mainly comprises a pen body, a sensing part disposed on the pen body, and a control module disposed in the pen body and electrically connected to the sensing part. When the active type capacitive touch control pen is used in a capacitive touch control panel, the control module receives a first drying signal from the touch control panel through the sensing part, detects the intensity of the first driving signal, and generates a second driving signal that is corresponding to the intensity of the first driving signal and inverted; and the second driving signal is sent to a corresponding sensing line on the touch control panel through the sensing part to stimulate a tough operation of a finger. Accordingly, the active type capacitive touch control pen can be operated independently without software and hardware technical supports from the touch control panel.

Description

technical field [0001] The invention relates to a capacitive touch pen, in particular to an active capacitive touch pen and a control method thereof. Background technique [0002] The known capacitive stylus can be divided into passive and active. Among them, the passive capacitive stylus has the advantages of simple structure and low cost. It mainly provides a pen tip made of conductive material. Grounding, or using material properties to simulate the dielectric coefficient of the human body, changes the sensing value when the pen touches the touch panel. However, the disadvantage of passive capacitive stylus is that it needs to touch more than a certain area to sense, so the tip is large, the accuracy is poor, and it cannot provide multi-level pressure classification. The active capacitive stylus does not have the above-mentioned limitations and disadvantages, but the existing active capacitive stylus cannot be applied to the general capacitive touch panel. For the use of...

Problems solved by technology

However, the disadvantage of the passive capacitive stylus is that it must touch more than a certain area to sense, so the tip is large, the accuracy is poor, and it cannot provide multi-level pressure classification

The active capacitive stylus does not have the above-mentioned limitations and disadvantages, but the existing active capacitive stylus cannot be applied to the general capacitive touch panel. For the use of the active capacitive stylus, the capacitive touch panel must The active capacitive stylus can only be used with a processor that supports the preceding function

In other words, the active capacitive stylus has technical support problems, and it cannot be used directly on the existing capacitive touch panel like the passive capacitive stylus, so there are many limitations and inconveniences in use

[0003] It can be known from the above that the active capacitive stylus has multi-level pressure classification and better performance, but it must have specific software and hardware support in the capacitive touch panel to use the active capacitive touch panel normally. Pen control, so there is obvious inconvenience
