Problems solved by technology

This means that the tip of the capacitive pen must be very thick in addition to its conductive properties, which results in poor writing fluency, difficulty in precise clicking, and no pressure-sensitive characteristics.
[0003] There are many companies in the market designing and producing capacitive touch devices, such as ATMEL, ELAN, SYNAPTICS, etc. Each of them has a different method of realizing the positioning of the capacitive pen and information interaction, so the capacitive pen designed for a certain company cannot be used in other companies. used on capacitive touch devices from companies

no. 1 approach

[0025] Refer below image 3 A circuit diagram of a general active capacitive pen according to the first embodiment of the present invention will be described.

[0026] Such as image 3 As shown, the universal active capacitive pen of the present invention includes: a pen head 300 and a pen tip 301, which are used to interact with the capacitive touch panel 10; a storage unit 311, which stores identification information and Corresponding communication protocol information; the controller 309, which controls the nib 30 and the nib 301 to receive the identification signal sent from the capacitive touch panel 10, and compares the received identification signal with the identification information stored in the storage unit 311 to identify The type of capacitive touch panel 10, control pen tip 300 and pen tip 301 to send corresponding communication protocol information to capacitive touch panel 10; amplifier 302; pulse generating circuit 304; wave detection circuit 306; boost circu...

no. 2 approach

[0043] Refer below Figure 7 A flow chart of a method for automatically identifying capacitive touch panels according to the second embodiment of the present invention will be described.

[0044] Such as Figure 7 As shown, the method receives the identification signal sent by the capacitive touch panel, thereby identifying the capacitive touch panel. In step S710, the controller 309 determines whether an A-capacitive touch panel is detected. If the A capacitive touch panel is detected (step S710, yes), that is to say, the received identification signal is consistent with the identification information of the A capacitive touch panel stored in the memory 311, then the process proceeds to step S720, and the controller 309 controls the pen tip 11 to send corresponding communication protocol information to the A capacitive touch panel. Then, the process ends.

[0045] If the A capacitive touch panel is not detected (step S710, No), that is to say, the received identification ...

Abstract

The invention provides an active type capacitive pen, a touch control device and a method for automatically recognizing a capacitive touch control panel. The active type capacitive pen (11) is used for conducting operating on the capacitive touch control panel (10). The capacitive touch control panel (10) sends an identification signal representing the type of the capacitive touch control panel. The active type capacitive pen comprises communication units (300 and 301), a storage unit (311) and a control unit (309), wherein the communication units (300 and 301) are in communication with the capacitive touch control panel (10), different types of identification information and corresponding communication protocol information of the capacitive touch control panel (10) are stored in the storage unit (311), and the control unit (309) controls the communication units (300 and 301) to receive identification signals sent by the capacitive touch control panel (10), compares the received identification signals with the identification information stored in the storage unit (311) so as to recognize the type of the capacitive touch control panel (10), and controls the communication units (300 and 301) to send the corresponding communication protocol information to the capacitive touch control panel (10).

Description

technical field [0001] The invention relates to an active capacitive stylus, a touch device and a method for automatically identifying capacitive touch panels, in particular to a general active capacitive stylus capable of working on different capacitive touch panels and a method for automatically identifying capacitive touch panels. Background technique [0002] Capacitive touch panels are popular for their ease of operation and multi-finger touch functions, and have become the first choice for touch devices at this stage. But in addition to the advantages of flexible finger control, the support for the pen has not been ideal. The reason is that the conductor detected by the capacitive touch panel needs to have a large contact area with the screen, so that the capacitance value of the sensor on the capacitive touch panel can be significantly changed, and the detection circuit can calculate the position of the conductor relatively accurately. This means that the tip of the ...
