A touch pen, touch controller, touch detection system and method thereof

Abstract

The invention is suitable for the technical field of touch control and provides a touch pen, a touch controller, a touch detecting system and a method thereof, wherein the touch pen comprises a nib and a pen body; the nib is connected with the pen body; the pen body has a hollow structure; a power supply, a microprocessor, a signal generating unit, a data detecting unit and an emitting unit are accommodated in the hollow structure; the power supply is used for supplying power to the data detecting unit, the microprocessor, the signal generating unit and the emitting unit; the data detecting unit is used for obtaining data information of the touch pen; the microprocessor is used for controlling the signal generating unit to generate a touch signal according to the data information of the touch pen and a driving signal; the generated touch signal is sent to the emitting unit; and the emitting unit is used for sending the touch signal to a touch sensor through the nib. The touch signal emitted by the touch pen provided by the embodiment of the invention comprises the driving signal and the data information of the touch pen; therefore multiple application functions of the touch pen are realized.

Description

technical field [0001] The invention belongs to the field of touch technology, and in particular relates to a touch pen, a touch controller, a touch detection system and a method thereof. Background technique [0002] Due to the support of multi-touch technology, capacitive touch screen has become the new darling of touch screen products. More and more devices are converting from resistive screens to capacitive screens. Due to hieroglyphs and traditional habits in eastern countries represented by China, most users are still accustomed to handwriting input. However, when handwriting input is performed on a capacitive touch screen, the following two problems will occur: (1) lost points: when the user When handwriting, the handwriting will be severely missing; (2) overflow point: after the finger is lifted, there will often be serious redundant handwriting. When the fingers are wet, the missing or overflowing phenomenon will be more serious, and the input cannot be realized a...

Problems solved by technology

Due to hieroglyphs and traditional habits in eastern countries represented by China, most users are still accustomed to handwriting input. However, when handwriting input is performed on a capacitive touch screen, the following two problems will occur: (1) lost points: when the user When writing by hand, the handwriting will be severely missing; (2) overflow point: after the finger is lifted, there will often be serious redundant handwriting

The current active capacitive stylus can only emit a single driving signal, which is only used to establish the coupling between the stylus and the touch sensor, and cannot transmit the various application functions of the stylus
