Abstract

Provided in the present disclosure is a capacitive pen for operating on a capacitive touch-control panel (200), comprising: a receiving unit (1) for receiving a measurement signal transmitted by the capacitive touch-control panel (200), a signal processing unit (5) for generating a high voltage signal synchronous with the measurement signal according to the signal received by the receiving unit (1), and a transmitting unit (2) for transmitting the high voltage signal to the capacitive touch-control panel (200) such that the capacitive touch-control panel (200) obtains the information of a capacitive pen (100). The capacitive pen of the present disclosure transmits a synchronous high voltage signal to enhance the sensing signal of a touch-control panel, such that the touch-control panel can sense a small-area conductor, thus expanding the function of the pen on the basis of finger touch control, and greatly improving user experience. In addition, the circuit is easy to realize, and has low cost and good compatibility.

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...
