Abstract

The invention discloses a capacitive pen and a capacitive pen writing system and method, relates to the field of computer peripheral equipment input, and aims to represent detailed feature of writing on a capacitive screen. The capacitive pen comprises conductive fibers, wherein the conductive fibers are formed by a plurality of mutually-insulated conductive fiber groups; and each conductive fiber group is electrically connected with one capacitance detection unit. The capacitive pen can be used for writing on the capacitive screen.

Description

technical field [0001] The invention relates to the input field of computer peripheral equipment, in particular to a capacitor pen, a capacitor pen writing system and a method. Background technique [0002] In recent years, along with the high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, the number of electronic devices in which a light-transmitting touch panel is mounted on the front of a display device such as a liquid crystal is increasing. Capacitive screen is one of the most widely used touch screens. The existing capacitive screen includes a transparent conductive layer, and the transparent conductive layer is connected with a plurality of electrodes. During use, a finger or a stylus is usually used to touch the surface of the capacitive screen, a contact capacitance is formed between the touch object and the transparent conductive layer, and the contact between the touch point and each electrode of ...
