Background

With the popularity of touch screen technology, touch pens have been widely used in smartphones, tablet computers, and other touch devices to provide a more accurate input pattern than fingers. The conventional stylus mainly relies on capacitive or resistive screen technology to operate, and performs an input command by simulating a change in human body current or pressure. However, these conventional styluses have some significant limitations and disadvantages.

First, many conventional touch pens are capable of triggering signals at a distance from the screen, and such "hover triggering" may cause misoperation, especially when performing fine operations such as drawing or writing, which may be prone to unnecessary pen strokes or wire breakage. In addition, the triggering mode lacks a necessary feedback mechanism, so that a user can hardly perceive whether the pen point is touched to the screen, and the accuracy of operation and the user experience are affected.

Second, prior art styluses are generally simpler in design, and most lack mechanical or electronic adjustment mechanisms that can accommodate different user operating habits and pressure changes. This limits the applicability and flexibility of the stylus in different application scenarios, especially in professional applications requiring highly accurate control.

Therefore, there is an urgent need to develop a new stylus design that can solve the problem of misoperation, provide more accurate control, and simultaneously have the characteristics of higher durability and convenient maintenance.
