Description

Capacitance pen

Technical field

The utility model is related to capacitance pen, more particularly to one kind can be simultaneously in common written medium and capacitance touch equipment The upper capacitance pen write.

Background technology

With the development of information technology, the electronic equipment of such as portable mobile apparatus and the life of people phase close all the more Close.This portable mobile apparatus can receive the input of user, and perform according to the input the desired function of user.As The input unit of user's input is received, contactor control device is widely used with its small volume, lightweight, easily operated advantage.

Contactor control device is broadly divided into two kinds, resistance type touch control device and capacitive touch device.Resistance type touch control device into This is low, easily fabricated, but can only support singly to refer to operation.The operability of capacitive touch device is relatively strong, support to refer to function more, Thus turn into the first choice of current contactor control device.

Capacitance touch-control device includes capacitive touch screen, the orthogonal electric capacity figure that capacitive touch screen can be by distribution thereon To perceive finger（Or stylus）Capacitance variations caused by touching, so as to measure touch location and touch intensity.Capacitive touch screen can Be located at capacitance touch-control device before transparent panel or opaque human-machine interaction board.

Because the electric conductor that can be perceived by touch screen needs larger contact area, so can cause positioning is inaccurate to ask Topic, while the support to pen is not ideal always.It is therefore expected that capacitance touch-control device can support the writing of pen, extremely Include very thin nib, hanging sensing, precise positioning, the pressure sensitivity function such as accurately less.

Active capacitance pen solves above mentioned problem, and it is a kind of capacitance pen used cooperatively with capacitive touch screen.It is actively electric The pulse signal synchronous with capacitive touch screen can be sent by holding pen, enhance capacitive sensing, so as to reduce contact area, together When fine point clearly enhance Consumer's Experience.
