When receiving the pressure sensitivity data of smart pen transmission, just show the track that smart pen is write, so as to avoid to detect touch control object and blocking
It is that the problem of display, can be achieved zero and touch height to infrared signal, is not in the infrared induction region into touch-screen
With regard to shown and produced touch height the problem of, the experience sense that pen is write on paper can be simulated, it is more intelligent.
It is a kind of schematic flow sheet of the implementation method for zero touch height that the embodiment of the present invention 2 is provided referring to Fig. 3, it is real
Example 2 is applied on the basis of embodiment 1, in addition to step：
If S4, judging that any instant is not received by the pressure sensitivity data, lower a period of time of any instant is treated
Be carved into up to when, judge whether the subsequent time of any instant scans the touch point of touch control object generation；
If during the touch point that the subsequent time scanning of S5, any instant is produced to the touch control object, judging described appoint
Whether the subsequent time at one moment receives the pressure sensitivity data that the touch control object is sent；
If S6, judging that the subsequent time of any instant receives the pressure sensitivity data, recognize that the touch control object is
Smart pen, and enter the smart pen write mode；If judging, the subsequent time of any instant is not received by the pressure
Feel data, it is conventional touch control object to recognize the touch control object, and enter conventional write mode；Wherein, the conventional touch control object is intelligence
Other touch control objects outside energy pen；The conventional write mode is that generation display is conventional to touch according to the touch point coordinate obtained in real time
Control the track of thing writing.
When it is implemented, a frame data can all be generated each time by scanning, each frame data include coordinate data and pressure sensitivity number
According to memory space.If the first frame data obtained at any one time include coordinate data but do not include pressure sensitivity data, examine
Whether survey the second frame data of the subsequent time formation of any instant includes pressure sensitivity data；If any instant is next
Moment includes coordinate data, but when not including pressure sensitivity data, it is believed that the touch control object is conventional touch control object, and enters conventional book
WriteMode.Wherein, the conventional touch control object is other touch control objects outside smart pen, and the conventional touch control object is without generation pressure sensitivity
The induction module of data and the wireless module for sending the pressure sensitivity data, the conventional write mode are according to touching for obtaining in real time
Control point coordinates, the track of the conventional touch control object writing of display.If the subsequent time of any instant includes coordinate data and pressure sensitivity
During data, then it is assumed that the touch control object is smart pen, and enters smart pen write mode.Pass through the coordinate to two continuous moment
The detection of data and pressure sensitivity data, can effectively recognize conventional touch control object and smart pen.Because, when the smart pen is in touch-screen
What the first frame entered when will scan, when the first frame scan terminates, smart pen is in and is going into state, i.e., do not arrive also
Up to the glass planar of touch-screen, but do not produce pressure sensitivity data now in the identification height of infrared touch frame yet, can produce
The situation of erroneous judgement, it is therefore desirable to the data that two continuous moment (subsequent time of i.e. described any instant and any instant) obtain
Frame can just obtain accurate result with reference to judgement.When it is conventional touch control object to recognize the touch control object, because pressure sensitivity can not be obtained
Data, therefore the response for making display, therefore the book of conventional touch control object whether can not be contacted according to the touch control object and touch-screen
The process of writing can not realize zero touch height.When conventional touch control object enters the plane of infrared light net, the glass of screen is not touched also
During plane, it can stop that the transmission of infrared light generates touch point so as to differentiate, can now upload the touch point and be shown,
Here it is writing process when being identified as conventional touch control object.
It is a kind of schematic flow sheet of the implementation method for zero touch height that the embodiment of the present invention 3 is provided referring to Fig. 4, it is real
Example 3 is applied on the basis of embodiment 2, in addition to step：
If S7, judging that any instant is not received by the pressure sensitivity data, cache what any instant was scanned
Touch point coordinate；
If the subsequent time of S8, any instant does not scan the touch point that the touch control object is produced, remove slow
The touch point coordinate that any instant in depositing is scanned；
If S9, judging that the subsequent time of any instant is not received by the institute in the pressure sensitivity data, display caching
State and enter the conventional write mode after the touch point coordinate that any instant is scanned.
This programme need to could judge the touch control object for conventional touch control object from the subsequent time of any instant, if not
Cache the touch point coordinate scanned of any instant, can cause the touch point coordinate of any instant go out active and
Situation about can not show, this has obviously run counter to the writing rules of conventional touch control object.Therefore, if not received in any instant
To the pressure sensitivity data, the touch point coordinate that any instant is scanned is cached；If the subsequent time of any instant does not have
When having the touch point that scanning is produced to the touch control object, the touch point coordinate that any instant in caching is scanned is removed,
Illustrate the touch control object and the simply false touch without writing, therefore the touch point coordinate without being scanned to any instant
It has been shown that, the caching can be removed；If judging, the subsequent time of any instant is not received by the pressure sensitivity data, display
Enter the conventional write mode after the touch point coordinate that any instant in caching is scanned, more meet conventional touch control object
Rule of response.
It is a kind of schematic flow sheet of the implementation method for zero touch height that the embodiment of the present invention 4 is provided referring to Fig. 5, it is real
Example 4 is applied on the basis of embodiment 1, in addition to step：
S10, in the smart pen write mode, if any time scanning to smart pen generation touch point but do not connect
Receive the pressure sensitivity data that the smart pen is sent, it is determined that smart pen is in lifting status；Wherein, when the smart pen is in lift
During the state of rising, the track of smart pen writing is not shown；
S11, in the smart pen write mode, if any time do not scan smart pen generation touch point, move back
Go out the smart pen write mode；
S12, in the conventional write mode, if any time do not scan smart pen generation touch point, exit
The conventional write mode.
Above-mentioned steps propose the processing mode of a variety of situations in the smart pen write mode and conventional write mode, with
Realize more smooth writing process.In the smart pen write mode, if any time scanning is to touching that smart pen is produced
Control point and the pressure sensitivity data for being not received by the smart pen transmission, it is determined that smart pen is in lifting status；Wherein, when described
When smart pen is in lifting status, the track of smart pen writing is not shown；When smart pen is in lifting status, but still it can sweep
When retouching coordinate data, without again identifying that the smart pen, without smart pen write mode is exited, do not upload what is scanned
Coordinate data is shown.By this scheme, company's pen writing of smart pen can be achieved, that is, nib is lifted slightly during writing
Rise, person's handwriting is from coarse to fine, the ways of writing for having of short duration disconnection between different strokes, realizes the simulation that pen is write on paper, even if
Exist it is of short duration between stroke and stroke lift, and the height lifted be located at scanning infrared red net in the range of, will not also show
The track that smart pen between stroke and stroke is passed through.In addition, in the smart pen write mode or conventional write mode, if
Any time does not scan the touch point of smart pen generation, then exits smart pen write mode or conventional write mode, return not
The state of touch point is scanned, when smart pen or conventional touch control object re-start writing, need to re-recognize and respectively enter phase again
