The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one

Referring to fig. 1, the method includes:
step S10: the digital board 2 senses data input information of the electromagnetic pen 3;
in the embodiment of the invention, the tablet 2 is arranged on the handwriting device, specifically, the tablet 2 is arranged below the display screen 1 of the handwriting device, the electromagnetic pen is arranged independently, the electromagnetic pen of the embodiment is specifically an electromagnetic pen based on a wireless passive technology, the electromagnetic pen does not have electromagnetism, and data input information is generated through electromagnetic induction with the tablet 2.
Specifically, many ring coils are distributed on the digitizer 2 in a vertical and horizontal direction, and within the range of the magnetic field generated by the digitizer 2, the movement of the digitizer pen can make the resonant loop of the electromagnetic pen accumulate weak electric energy, and after the pen accumulates the energy, the control loop will stop supplying current to the circulating coil and connect the circulating coil to the receiving loop. At this time, the energy accumulated in the pen is transmitted from the coil of the pen tip back to the digitizer tablet 2 by free oscillation of the resonance circuit. In this case, the control circuit first scans the circulation coils on the digitizer 2 to initially detect the approximate position of the digitizer pen, then scans the plurality of circulation coils around the digitizer pen, and calculates the detected signal, thereby calculating the coordinate value of the digitizer pen with high accuracy. Such a cyclic reciprocation of the operation can sense data input information of coordinates, inclination, and operation state (speed, pressure of the pen) of the pen.
Specifically, the passive wireless electromagnetic pen 3 does not have a power supply and cannot generate a magnetic field naturally, the electromagnetic pen 3 works by absorbing the magnetic field of the board surface of the digital board 2, then energy is accumulated to transmit an electromagnetic signal to the digital board 2, and the electromagnetic pen interacts with the magnetic field of the board surface of the digital board 2.
Specifically, the data input information refers to information representing coordinates, inclination, operation state (speed, pen pressure feeling) and the like of the electromagnetic pen contact on the digital plate 2, which is generated when the electromagnetic pen 3 is in touch-pressure sliding on the digital plate 2, and specifically, the data input information contains longitudinal pressure data of X/Y coordinates and Z of the electromagnetic pen contact when the electromagnetic pen is in touch-pressure sliding on the digital plate; however, the handwriting device, as a portable mobile device, is not suitable for loading an image processing unit with powerful image processing capability, and the powerful image processing unit is usually accompanied by larger hardware, higher power consumption, larger heat generation amount, and higher cost, and these disadvantages make it unsuitable for setting a powerful image processing unit on the handwriting device.
Step S20: the control panel 4 of the electromagnetic pen 3 sends the data input information to a terminal;
in this embodiment, the electromagnetic pen control board 4 is disposed in the handwriting device, one end of the electromagnetic pen control board 4 is electrically coupled to the tablet 2, and the other end of the electromagnetic pen control board is connected to the signal output port 7, the signal output port 7 of the invention is mainly a Type-C signal output port 97, and the signal output port 7 is mainly used for outputting data input information of the tablet 2. The electromagnetic pen control board 4 is mainly used for storing data input information generated on the digitizer tablet 2 and sending the data input information to the external terminal 12 connected to the Type-C signal output port 97 through the Type-C signal output port 97.
Specifically, the terminal may be one or a combination of several of a Personal Computer (PC), a notebook Computer, a Personal Digital Assistant (PDA), a smartphone terminal, and a tablet terminal.

in this embodiment, the terminal converts the data input information into the graphic output information through the image processing unit mounted on the terminal, and the image processing unit mounted on the terminal may be an image processing unit in the prior art, and the image processing unit is understood as integration of hardware and software.
Specifically, the data input information refers to information representing coordinates, inclination, operation state (speed, pen pressure feeling) and the like of the electromagnetic pen contact on the digital plate 2, which is generated when the electromagnetic pen 3 is in touch-pressure sliding on the digital plate 2, and specifically, the data input information contains longitudinal pressure data of X/Y coordinates and Z of the electromagnetic pen contact when the electromagnetic pen is in touch-pressure sliding on the digital plate; the information is converted into an electromagnetic induction signal carrying the information through an electromagnetic pen control panel 4, and is sent to an image processing unit on the terminal, the image processing unit converts the data input information into specific graphic information output information such as the writing track of the electromagnetic pen on the digital panel 2, namely the thickness of lines formed by writing the information, and the graphic output information is in a data form which can be directly used for display of display equipment under the drive of corresponding software, and in the embodiment, the graphic output information is image information which can be directly displayed on the display equipment of the terminal and the display screen 1 of the handwriting device.
Step S40: and the terminal displays the graphic output information to a terminal display interface and sends the graphic output information to a display driving board 5 of the handwriting device.
In this embodiment, the display device mounted on the terminal may directly display the graphical output information, and naturally, the user may choose not to display the graphical output information on the display device of the terminal, and the terminal displays the graphical output information as a conventional practice in the art, which should not be construed as a limitation to the scope of the invention.
Specifically, the terminal display interface refers to a display device of the terminal, and may be a conventional liquid crystal display 1, or may be another display 1 capable of displaying an image. The terminal display interface can display simple graphic output information or other image information containing the graphic output information.
Specifically, the terminal sends the graphic output information to the signal input port 8 of the handwriting device, in this embodiment, the signal input port 8 is mainly used for inputting image information, and therefore, the signal input can be selected in multiple ways to match different terminal connection requirements, for an old version of terminal, the handwriting device can be equipped with the HDMI signal input port 108 to adapt to the port configuration of the old version of terminal, and for a new version of terminal, the new version of terminal generally supports the Type-C signal output port 97 as an image information transmission port.
Specifically, the graphic output information is transmitted to the display driver board 5 connected to the signal input port 8 through the signal input port 8, in this embodiment, one end of the display driver board 5 is connected to the display screen 1, the other end of the display driver board 5 is connected to the signal input port 8, and the display driver board 5 stores the graphic output information and displays the graphic output information on the display screen 1.
Step S50: the display driver board 5 displays the graphic output information on the display screen 1 of the handwriting device.
Specifically, the display screen 1 is disposed on the handwriting device, the display screen 1 is configured to display image information, the image information is image information that the terminal synchronizes to the handwriting device, naturally, the content of the image information is not limited to the graphic image depicted by the tablet 2 of the handwriting device, and the image information may be an original image on the display interface of the terminal device, may also be a simple handwriting image depicted by the user on the handwriting device, and may also be an integrated image of the handwriting image depicted by the user on the handwriting device and the original image on the display interface of the terminal device.
Specifically, the integrated image refers to image information including all or part of two images, which is formed by combining the two images through a certain logic, and may be displayed on the left and right or upper and lower parts of the same display screen 1 in a parallel coexisting manner, or may be displayed in the same area of the same display screen 1 in an overlapping manner, and the specific image configuration may be specifically configured according to the specific requirements of the user.
In this embodiment, only the image drawn by the user on the handwriting device is displayed on the display screen 1 of the handwriting device, so that the user can confirm the track state input into the handwriting device on the display screen 1 while sliding the electromagnetic pen 3 on the display screen 1 of the handwriting device to draw the track, thereby improving the work efficiency of the user.
Example two
Referring to fig. 2, the difference between the second embodiment and the first embodiment is: s10, before the step of the tablet 2 sensing the data input information of the electromagnetic pen 3, the method further includes:
and S01, synchronizing the terminal image information of the terminal display interface to the display screen 1 of the handwriting device.
And the number of the first and second groups,
s40, the terminal displays the graphic output information to a terminal display interface and sends the graphic output information to a display driving board 5 of a handwriting device; s50 the step of the display driver board 5 displaying the graphical output information on the display screen 1 of the handwriting apparatus further includes:
s41a the terminal integrates the terminal image information and the graphic output information into integrated information of an image superposition state;
s42a, the terminal displays the integrated information of the image superposition state to a terminal display interface;
s43a, the terminal sends the integrated information of the image superposition state to a display driving board 5 of the handwriting device;
s51a the display driving board 5 displays the integrated information on the display screen 1 of the handwriting device.
In this embodiment, a terminal is equipped with a display device, and specifically, terminal image information is displayed on a terminal display interface of the display device.
In a specific application scene, the terminal image information is a template image, the template image of the terminal display interface is synchronously displayed on a display screen 1 of the handwriting device, a user copies the template image on the display screen 1 by using an electromagnetic screen according to the template image, and an electromagnetic pen 3 is matched with a digital board 2 below the display screen 1 to generate data input information.
In the embodiment, the terminal image information of the terminal display interface is synchronized to the display screen 1 of the handwriting device through the terminal to be displayed, so that the user can directly compare the terminal image information on the display screen 1 of the handwriting device when needing to compare the image for drawing and writing.
Naturally, the synchronization of the terminal image information to the display screen 1 of the handwriting device for display is not contradictory to the synchronization of the terminal image information to the display screen 1 of the handwriting device after the data input information generated on the handwriting device is transmitted to the terminal equipment for conversion into the graphic output information and then is synchronized to the display screen 1 of the handwriting device for display. Before a user works on the handwriting device, the terminal synchronizes terminal image information to the handwriting device for the user to refer to, and after the user starts working on the handwriting device, the terminal synchronizes integrated information integrated with graphic output information and the terminal image information to the handwriting device so as to replace simple terminal image information.
Naturally, the user may choose that the terminal always synchronizes only the terminal image information to the handwriting device, and that the integrated information integrated with the graphic output information and the terminal image information is synchronized to the handwriting device. The technical solution disclosed in this embodiment that the terminal synchronizes the integrated information integrated with the graphical output information and the terminal image information to the handwriting device after the user starts to work on the handwriting device, so as to replace the simple terminal image information, should not be considered as a limitation to the flexible selection of the user, but as a limitation to the protection scope of the present invention.
Specifically, in the second technical solution of the embodiment, before the user starts to work on the handwriting apparatus, the terminal device synchronizes the terminal image information on the terminal display interface to the display screen 1 of the handwriting apparatus for displaying, so that the user can copy the image on the display screen 1 of the handwriting apparatus according to the terminal image information.
Step S30, after the step of converting the data input information into the graphic output information by the terminal:
s41a the terminal integrates the terminal image information and the graphic output information into integrated information of an image superimposition state.
Specifically, the integrated information of the superimposed state should be understood as image information that is formed by combining two images by a certain logic and that includes all or part of the two images, and that is displayed in an overlapping manner in the same area of the same display screen 1.
Step S41a is after the integration information step of the terminal integrating the terminal image information and the graphics output information into an image superimposition state:
s42a, the terminal displays the integrated information of the image superposition state to a terminal display interface;
specifically, data input information sent by the handwriting device to the terminal is converted into graphic output information on an image processing unit of the terminal, the graphic output information and the original terminal image information on the display interface of the terminal are integrated into integrated information in an image superposition state, and the integrated information is displayed on the display interface of the terminal. Generally speaking, the display device of the terminal is larger and has higher resolution than the display screen 1 of the handwriting device, and for fine details, the user still needs to confirm the drawing track through the display of the terminal device, so that the graphical output information needs to be displayed not only on the display screen 1 of the handwriting device, but also on the terminal device.
Naturally, the user may choose that the user can select to display the terminal image information on the terminal display interface of the terminal device, or may choose to display only the graphical output information on the terminal display interface, instead of displaying the integrated information integrated with the graphical output information and the terminal image information, and synchronizing the integrated information with the handwriting device. The technical solution disclosed in this embodiment is that after a user starts to work on a handwriting device, a terminal displays integrated information integrated with graphical output information and terminal image information on a terminal display interface of the terminal and a display screen 1 of the handwriting device, so as to replace simple terminal image information, and the integrated information is not considered as a limitation on flexible selection of the user, but as a limitation on the protection scope of the present invention.
Step S42a, after the terminal displays the integrated information of the image superimposition state on the terminal display interface:
s43a the terminal transmits the integrated information of the image superimposition state to the display driving board 5 of the handwriting device.
Specifically, the integrated information is sent from the terminal to the signal input port 8 of the handwriting device, in this embodiment, the signal input port 8 is mainly used for inputting image information, and therefore, the signal input can be selected in multiple ways to match different terminal connection requirements, for an old version of terminal, the handwriting device can be equipped with the HDMI signal input port 108 to adapt to the port configuration of the old version of terminal, and for a new version of terminal, the new version of terminal generally supports the Type-C signal output port 97 as an image information transmission port.
Specifically, the graphic output information is transmitted to the display driver board 5 connected to the signal input port 8 through the signal input port 8, in this embodiment, one end of the display driver board 5 is connected to the display screen 1, the other end of the display driver board 5 is connected to the signal input port 8, and the display driver board 5 stores the graphic output information and displays the graphic output information on the display screen 1.
Step S43a after the terminal transmits the integrated information of the image superimposition state to the display driving board 5 of the handwriting device:
s51 the display driving board 5 displays the integrated information on the display screen 1 of the handwriting device.
This step S51 is different from the step S50 of the first embodiment in that the display driver board 5 displays the integrated information of the image superimposition state of the terminal image information and the graphic output information on the display screen 1 of the handwriting device. In the first embodiment, the terminal device synchronizes only the graphical output information to the handwriting device.
