Problems solved by technology

For example, it can be through wireless communication, but it will increase the cost and power consumption of wireless communication. The controller or host that detects the active stylus must also have the ability of wireless communication, which increases the complexity of the system.
In addition, the force information on the pen tip can be represented by the magnitude of the analog signal, but it may be misjudged due to changes in temperature or humidity, distance between the pen and the touch panel, and noise interference

Abstract

The present invention provides a touch processing device and a detecting method and a touch system. The invention provides a first transmitter comprising a first sensitive machine; and a processing module connected to the sensitive machine, wherein the processing module is used for sending a first electric signal in a first time frame. The first electric signal is used for representing at least one part of a digital sensitive value of the first sensitive machine. The technical scheme of the invention provides an active touch pen which can actively and accurately transmit the electric signal when subject to the pressure.

Description

[0001] This patent application is a divisional application of the invention patent application with the application number 201510242300.5 named "Sender and its control method", and the filing date of the original application is 2015-05-13. technical field [0002] The present invention relates to transmitters, and more particularly to transmitters that actively transmit pressure-related sensory information. Background technique [0003] Touch panel or touch screen is an important human-machine interface in modern times. In addition to detecting approaching or touching (collectively referred to as proximity) human body, touch panel is also used to detect approaching pen-like objects or touch The nib of the pen is used to facilitate the user to more precisely control the trajectory of the pen nib touch. [0004] The stylus can use the tip of the stylus to actively send out electrical signals, which is referred to as an active stylus in this paper. When the pen tip is close to...
