Problems solved by technology

[0003] However, if a capacitive touch screen is operated with a thin pen tip made of conductive material, although the pen tip will also absorb part of the current from the contact point, because the pen tip is very thin, the absorption current has little effect on the receiving electrode and is difficult to detect, making the capacitive touch screen impossible. determi

Abstract

The invention provides a capacitive stylus used for operations on a capacitive touch panel (200). The capacitive stylus comprises a transmitting unit (1) and a capacitive stylus control processing unit (2). The transmitting unit is used for transmitting high-voltage alternating current signals to the capacitive touch panel (200). The capacitive stylus control processing unit is used for generating high-voltage alternating current signals; the signals are transmitted to the capacitive panel (200) by the transmitting unit (1), so that the capacitive touch panel (200) can measure location of the capacitive stylus (100) according to the high-voltage alternating current signals. The capacitive stylus has the advantages that the high-voltage alternating current signals are transmitted to the capacitive touch panel to allow the capacitive touch panel to locate according to the high-voltage alternating current signals; the strength of the high-voltage alternating current signals is high, so that signal to noise ratio and locating precision can be increased.

Description

technical field [0001] The invention relates to touch technology, in particular to a capacitive pen, a capacitive touch panel and a touch device. Background technique [0002] At present, because the capacitive touch screen is easy to operate and has high sensitivity, it has become the first choice for touch devices at this stage. Capacitive touch screens used in capacitive touch screens are generally made of transparent conductive ITO (indium tin oxide) films in glass or other transparent materials to form a criss-cross structure of conductive films, which can be used as sending electrodes and receiving electrodes. When a finger taps the screen, it will form a coupling capacitance with both the sending electrode and the receiving electrode, and absorb part of the current from the contact point, thereby causing the signal of the receiving electrode to change. That is, when the conductor touches the capacitive touch screen, the touch position of the conductor on the capaciti...
