Description

Detachable pen point for capacitance pen

Technical Field

Background

Along with the smart phone, the horizontal line of panel computer, market potential is huge, and the appearance of electric capacity pen is just for better input cell-phone and panel computer, and the user does not need to use the finger to operate for a long time, has avoided the fatigue that long-time amusement work brought. For example, many people draw pictures with electronic products, and if the people touch the pictures with fingers for a long time, many defects are reflected, such as fatigue, inaccurate touch, too thick fingers, sweating and the like can influence touch writing. The advent of capacitive stylus solved this problem.

When a finger touches the metal layer, a coupling capacitor is formed by the electric field of a human body, a user and the surface of the touch screen, and for high-frequency current, the capacitor is a direct conductor, so that the finger sucks a small current from a contact point. The currents respectively flow out of the electrodes on the four corners of the touch screen, the currents flowing through the four electrodes are in direct proportion to the distances from the fingers to the four corners, and the controller accurately calculates the proportion of the four currents to obtain position information of a touch point. The capacitance pen is an auxiliary device which uses conductor materials to imitate human bodies (usually fingers) to complete man-machine conversation.

Because long-term and high frequency use the electric capacity pen, cause the nib wearing and tearing of electric capacity pen easily, lead to the touch response slow or even the inflexible condition, also be inconvenient for change moreover, present electric capacity pen nib does not have fine solution this problem.
