Hand-written touch pen

Abstract

The invention provides a handwritten touch-pen, comprising a pen holder and a brush touch, characterized in that, the pen holder and brush touch are connected into a carrier capable of passing induction current of human bodies onto a capacitor touch screen. The invention well solves the inconvenient caused by directly touching the screen by fingers and the troubles brought to users by not meeting demands of such touch screen as common handwritten touch-pens are not provided with electrical conductivity, by using the carrier formed by connecting the pen holder and brush, capable of passing induction current of human bodies onto a capacitor touch screen. The invention is convenient to popularize with a simple structure and easy service method.

Description

Technical field [0001] The invention relates to a stylus, in particular to a handwriting stylus used on a mobile phone with a capacitive touch screen or other electronic products with a capacitive touch screen. Background technique [0002] At present, an ordinary handwriting stylus generally includes three parts: a pen shaft, a brush stroke, and a pen tip. The stroke part is usually made of plastic or other non-conductive materials, and the handwriting stylus does not have conductive properties as a whole. For general electronic products with a touch screen, this ordinary handwriting stylus or a human finger can meet the requirements of using the touch screen. But for electronic products with capacitive touch screens, because the working principle of the touch screen is that when a finger touches the touch screen layer, the human body and the surface of the touch screen form a coupling capacitor due to the electric field of the human body. For high-frequency current, the capacit...

Problems solved by technology

However, for electronic products with capacitive touch screens, due to the working principle of the touch screen, when a finger touches the touch screen layer, due to the electric field of the human body, the human body and the surface of the touch screen form a coupling capacitance. For high-frequency currents, the capacitance is directly Conductor, so the finger sucks a small current from the contact point, this current flows out from the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners, the controller passes through The accurate calculation of these four current ratios can determine the position of the touch point, so the ordinary stylus cannot meet the requirements of using this kind of touch screen due to its non-conductivity, which brings some inconvenience to the user.
