[0025] It should also be understood that, although the present disclosure has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present disclosure that have the features of the claims and are therefore within the scope of protection defined thereby.

[0026] The above and other aspects, features and advantages of the present disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0027] Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are merely examples of the present disclosure, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present disclosure in a variety of ways with substantially any suitable detailed structure.

[0028] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0029] With the development of electronic devices, more and more touch display devices are used in people's daily life, especially for devices with large screens. Users can use the stylus pen that comes with the device to achieve the effect of writing on paper, making the device widely used in various learning or working occasions. In addition, in conference scenarios, there are often multiple people discussing, writing, and annotating, so a touch all-in-one computer with a larger screen can be used to meet the needs of multi-person collaboration.

[0030] However, touch display devices are generally limited to writing with the stylus that is bound to it, especially devices placed in public areas such as conference rooms, which only allow writing with the stylus and cannot be directly operated with fingers. In conference rooms, the stylus bound to the device often gets taken by mistake or lost, which causes inconvenience in writing. At the same time, the bound stylus cannot be used on other touch all-in-one machines. In addition, although the touch all-in-one machine can support multiple people writing at the same time, it is often impossible to distinguish which handwriting belongs to which user after writing, which brings inconvenience to the arrangement of written records.

[0031] In order to solve the above problems, the first embodiment of the present disclosure provides a stylus, the structural diagram of which is shown in FIG. Figure 1 As shown, the stylus pen 10 mainly includes a pen holder 11, a stylus pen tip 12 disposed at one end of the pen holder 11, a near field communication storage module 13 disposed on the pen holder 11, and an electromagnetic wave transmitting device 14 disposed inside the pen holder 11. Before use, the stylus pen 10 provided in this embodiment can realize rapid registration and binding with a touch display device according to user data stored in the near field communication storage module 13, and transmit electromagnetic waves of a specified frequency band for representing its own user information when writing, so as to facilitate collection and recognition by the touch display device.

[0032] Specifically, the near field communication storage module 13 may be an NFC chip attached to the outer wall of the pen body 11, which is usually a passive chip and can store a certain amount of information without power supply. In this embodiment, the near field communication storage module 13 is used to store user information, which may include basic information such as the user name and avatar of the user using the current stylus. In actual use, the user can input the user information to be written into the stylus 10 on the mobile terminal, and write the user information into the near field communication storage module 13 of the stylus 10 through the near field communication writing module of the mobile terminal, and the user information stored in the near field communication storage module 13 in the stylus 10 can be updated at any time according to the user's changes. The mobile terminal may be a mobile phone with NFC function or a card reader with writing function, etc.

[0033] It should be noted that due to the short transmission distance of NFC, in order to ensure that data can be accurately written or read, when writing user information, the near-field communication storage module 13 of the stylus 10 should directly contact the near-field communication writing module of the mobile terminal to achieve the best writing effect.

[0034] Furthermore, the electromagnetic wave transmitting device 14 is mainly used to transmit electromagnetic waves of a specified frequency band when the stylus 10 is used for writing. It can be set on a side close to the stylus tip 12. Its output power does not need to be set too high, as long as it can be received by the touch display device that is in contact with the stylus tip 12 after transmission. The frequency band of the electromagnetic waves transmitted by the electromagnetic wave transmitting device 14 is allocated by the touch display device according to the user information read, that is, by allocating different specified frequency bands to different user information, it can be realized that when it receives the electromagnetic waves of the corresponding specified frequency band, it can judge the current writing user. The electromagnetic wave transmitting device 14 can receive the specified frequency band allocated by the touch display device, and transmit electromagnetic waves according to the specified frequency band when in use.

[0035] In some embodiments, the stylus 10 may further include a pressure sensing layer ( Figure 1 The pressure sensing layer 14 is used to determine whether the stylus 10 is in a writing state. The pressure sensing layer 14 is not shown in the figure. The pressure sensing layer 14 is used to determine whether the stylus 10 is in a writing state ...

[0036] It should be understood that the stylus 10 may also include a power supply to power the electromagnetic wave emitting device 14 or the pressure sensing layer, may also include a switch to turn the stylus 10 on or off, and may also include elements or structures for realizing other functions of the stylus 10, which are not described in detail in this embodiment.

[0037] This embodiment records user information by setting a near-field communication storage module on the stylus pen, and realizes the interaction of user information when the stylus pen is close to the near-field communication reading module of the touch display device for recording by the touch display device, thereby achieving the purpose of rapid binding and registration between the stylus pen and the touch display device; at the same time, the stylus pen actively sends electromagnetic waves of a specified frequency band during use, and the touch display device determines the corresponding user based on the received electromagnetic wave frequency band, thereby realizing the distinction between handwritings of multiple people, and facilitating the organization and use of written records.

[0038] The second embodiment of the present disclosure provides a touch display device, which generally has a larger touch display screen, and can be used to write or annotate on the screen by using the stylus pen disclosed in the first embodiment of the present disclosure. Specifically, Figure 2 FIG. 2 shows a schematic diagram of the structure of a touch display device 20, which mainly includes a touch display screen 21, a near field communication reading module 23 and a processor 24, wherein the touch display screen 21 includes at least an electromagnetic wave receiving unit 22 ( Figure 2 (not shown), the electromagnetic wave receiving unit 22 is composed of a plurality of electromagnetic wave receiving devices arranged in an array, and is used to receive the electromagnetic wave signal emitted by the stylus. In actual preparation, the electromagnetic wave receiving unit 22 can be one of the many hierarchical structures in the touch display screen 21.

[0039] Specifically, the near field communication reading module 23 is also based on the communication principle of NFC. When it contacts the near field communication storage module in the stylus, it can read the user information stored in the near field communication storage module and transmit it to the processor 24, so as to realize the rapid acquisition and registration of user information without other means such as Bluetooth or USB, and can also register the user information in multiple styluses at the same time. In some embodiments, the near field communication reading module 23 can be a module built into the main body of the touch display device, or it can be an NFC reading device independent of the touch display device that is connected to the processor 24 for communication. The present embodiment does not limit its specific installation method, as long as it can realize the acquisition and transmission of user information.

[0040] The size of the electromagnetic wave receiving unit 22 in this embodiment should be the same as the screen size of the touch display screen 21 to ensure that when the stylus touches any position on the touch display screen 21, there is an electromagnetic wave receiving device that can receive the electromagnetic wave signal emitted by the stylus, which can usually be placed under the display panel of the touch display screen 21. When making the electromagnetic wave receiving unit 22, multiple electromagnetic wave receiving devices can be arranged according to the arrangement of pixels in the touch display screen 21, and when selecting the electromagnetic wave receiving device, a small-volume model is preferably used to achieve more refined position positioning when receiving electromagnetic wave signals. Further, each electromagnetic wave receiving device in this embodiment corresponds to a coordinate value of a position to characterize the position of the electromagnetic wave receiving device in the touch display screen, and when the stylus touches the touch display screen 21, the electromagnetic wave receiving device corresponding to the touch position can receive the electromagnetic wave signal, and the coordinate value of the electromagnetic wave receiving device can be used to indicate the specific position of the stylus touching the touch display screen 21.

[0041] It should be noted that, in addition to the electromagnetic wave receiving unit 22, the touch display screen 21 should also include other elements or structures for realizing touch functions and display functions, such as a backlight module, a display panel, a packaging cover, etc. This embodiment does not make specific restrictions and descriptions. The specific elements or structures used shall be based on the actual functions that can be realized by the touch display device.

[0042] The processor 24 is built into the touch display device, such as Figure 2 As shown in the dotted box, it is connected to the touch display screen 21, the electromagnetic wave receiving unit 22 and the near field communication reading module 23 respectively. It is mainly used to assign a specified frequency band to the user information after obtaining the user information read by the near field communication reading module 23 and inform the stylus, and record the corresponding relationship between the user information and the specified frequency band, so that the subsequent processor 24 can judge the current writing user according to the received electromagnetic wave frequency band. Specifically, when the stylus writes on the touch display screen 21, it will emit electromagnetic waves of the specified frequency band, and the electromagnetic wave receiving device at the corresponding position in the touch display screen 21 will receive the electromagnetic waves of the frequency band. The processor 24 can determine the position currently touched by the stylus according to the coordinates of the electromagnetic wave receiving device that receives the electromagnetic wave, and at this time, the corresponding control touch display screen 21 can present the handwriting of the current user information at the position corresponding to the coordinate.

[0043] In actual use, in order to achieve simultaneous writing by multiple people, the touch display device 20 can obtain and record the user information stored in multiple styluses, and allocate different designated frequency bands to different user information through the processor 24, for example, the frequency band allocated to user A is 130 Hz, the frequency band allocated to user B is 200 Hz, and the frequency band allocated to user C is 70 Hz, etc. Further, after different designated frequency bands are allocated to different users, the user information needs to be associated and stored with the designated frequency bands. When the processor 24 determines that electromagnetic waves of multiple different designated frequency bands are received at the same time, the touch display screen 21 is controlled to use different colors to display the trajectories of electromagnetic waves of different designated frequency bands, that is, different colors are used to represent the handwriting of different users. While displaying the handwriting, the user name or user avatar of the user who is currently writing can also be displayed on the screen to achieve a better display effect.

[0044] In some embodiments, the processor 24 can also export the handwriting of the currently presented user according to the user's control instructions. The export operation can be performed on any one of multiple users, or the handwriting of multiple users can be exported to one file at the same time. The specific setting can be made according to the actual usage requirements of the user.

[0045] In some embodiments, when the touch display device is used in public places, in order to prevent other people from writing, the administrator information can be pre-set in the processor 24, and the writing function can only be realized by using the stylus registered by the administrator. Specifically, after obtaining the user information, the processor 24 compares the obtained user information with the administrator information to determine whether the two are the same. If the user information is the same as the administrator information, the processor 24 can allocate a specified frequency band for the current user so that he can write. If the user information is not the same as the administrator information, the frequency band allocation is not performed. At this time, even if the user uses the stylus to write on the screen, since the electromagnetic wave receiving device cannot receive the electromagnetic waves of the specified frequency band sent by the stylus, the touch display screen 21 cannot display its writing track.

[0046] During actual execution, the processor 24 may also detect whether the designated frequency of the electromagnetic wave received by the electromagnetic wave receiving device is the same as the designated frequency band pre-assigned to the administrator information after the electromagnetic wave receiving device receives the electromagnetic wave of the designated frequency. Only when the frequency of the received electromagnetic wave is the same as the designated frequency pre-assigned to the administrator information, it is determined that the stylus currently writing on the touch display screen 21 belongs to the administrator, and the writing trajectory can be displayed accordingly on the touch display screen 21.

[0047] In addition, in actual use, the processor 24 can also detect whether the frequency band of the electromagnetic wave received by the current electromagnetic wave receiving device is the frequency band allocated by the processor 24. For example: the stylus used by user A is registered on the touch display device X, and the frequency band allocated by the touch display device X to user A is 130 Hz, that is, the electromagnetic wave emitted by the stylus of user A when writing is 130 Hz; if user A uses the stylus to write on the touch display device Y, but it is not registered on the touch display device Y, for the touch display device Y, although it receives the electromagnetic wave of 130 Hz, the designated frequency band is not allocated by the touch display device Y, and the processor of the touch display device Y can control its touch display screen to display a prompt message to inform the user that the current stylus is not registered and cannot be used.

[0048] It should be noted that a stylus can generally only be registered and associated with one touch display device, that is, the frequency band of the electromagnetic waves it emits can only be allocated by the touch display device after it is registered and associated with it. If the stylus needs to be used on other touch display devices, its near-field communication storage module should be in contact with the near-field communication reading module of the touch display device before use to realize the transmission of user information, and it can be used after waiting for the touch display device to allocate the specified frequency band.

[0049] This embodiment records user information by setting a near-field communication storage module on the stylus pen, and realizes the interaction of user information when the stylus pen is close to the near-field communication reading module of the touch display device for recording by the touch display device, thereby achieving the purpose of rapid binding and registration between the stylus pen and the touch display device; at the same time, the stylus pen actively sends electromagnetic waves of a specified frequency band during use, and the touch display device determines the corresponding user based on the received electromagnetic wave frequency band, thereby realizing the distinction between handwritings of multiple people, and facilitating the organization and use of written records.

[0050] The third embodiment of the present disclosure provides a communication method for a stylus, which is mainly applied to the stylus provided in the first embodiment of the present disclosure. Specifically, when the stylus is in use, the electromagnetic wave transmitting device transmits electromagnetic waves of a specified frequency band to achieve communication between the stylus and the touch display device. It should be noted that the frequency band of the electromagnetic waves transmitted is allocated by the touch display device based on the user information stored in the near field communication storage module of the stylus, so as to facilitate the touch display device to distinguish users.

[0051] During actual use, the user can input the user information that needs to be written into the stylus on the mobile terminal, and write the user information into the near-field communication storage module of the stylus through the near-field communication writing module of the mobile terminal. The user information stored in the near-field communication storage module in the stylus can be updated at any time according to the user's changes. The mobile terminal can be a mobile phone with NFC function or a card reader with writing function, etc.

[0052] This embodiment records user information by setting a near-field communication storage module on the stylus pen, and realizes the interaction of user information when the stylus pen is close to the near-field communication reading module of the touch display device for recording by the touch display device, thereby achieving the purpose of rapid binding and registration between the stylus pen and the touch display device; at the same time, the stylus pen actively sends electromagnetic waves of a specified frequency band during use, and the touch display device determines the corresponding user based on the received electromagnetic wave frequency band, thereby realizing the distinction between handwritings of multiple people, and facilitating the organization and use of written records.

[0053] The fourth embodiment of the present disclosure provides a communication method for a touch display device, which is mainly applied to the touch display device provided in the second embodiment of the present disclosure. The method flow chart is as follows: Figure 3 As shown, it mainly includes steps S1 to S3:

[0054] S1, when the near field communication reading module contacts the near field communication storage module of the stylus, obtaining user information recorded in the near field communication storage module;

[0055] S2, assigning a designated frequency band to the user information, and obtaining the coordinates of the electromagnetic wave receiving device that receives the electromagnetic wave of the designated frequency band when the electromagnetic wave receiving device in the electromagnetic wave receiving unit receives the electromagnetic wave of the designated frequency band;

[0056] S3, controlling the touch screen to present handwriting corresponding to the electromagnetic wave of the specified frequency band at the position corresponding to the coordinates.

[0057] It should be noted that in order to enable multiple people to write at the same time, the touch display device can obtain and record the user information stored in multiple styluses, and assign different designated frequency bands to different user information through the processor. When electromagnetic waves of multiple different designated frequency bands are received at the same time, the touch display screen is controlled to use different colors to display the trajectories of electromagnetic waves of different designated frequency bands, so as to achieve the purpose of distinguishing the handwriting of different users, optimize the use effect of the stylus, and facilitate the user's intuitive viewing.

[0058] In some embodiments, the touch display device can also export the handwriting of the currently presented user according to the user's control instructions. The export operation can be performed on any one of multiple users, or the handwriting of multiple users can be exported to one file at the same time. The specific settings can be made according to the user's actual usage needs.

[0059] In some embodiments, after obtaining the user information recorded in the near-field communication storage module, it can also include comparing the obtained user information with the pre-set administrator information to determine whether the two are the same. If the two are the same, frequency band allocation can be performed for registration. If the two are different, frequency band allocation is not performed, and the writing function can be implemented by prompting the user to use the administrator's stylus pen.

[0060] In some embodiments, after the electromagnetic wave receiving device receives the electromagnetic wave of the specified frequency band, it is also possible to detect whether the specified frequency band of the electromagnetic wave received by the electromagnetic wave receiving device of the electromagnetic wave receiving unit is the same as the specified frequency band corresponding to the administrator information; when the specified frequency band of the electromagnetic wave received by the electromagnetic wave receiving device of the electromagnetic wave receiving unit is the same as the specified frequency band corresponding to the administrator information, the coordinates of the electromagnetic wave receiving device of the electromagnetic wave receiving unit that receives the electromagnetic wave of the specified frequency band of the electromagnetic wave receiving unit are obtained, and the touch display screen of the electromagnetic wave receiving unit is controlled to present the handwriting corresponding to the administrator information of the electromagnetic wave receiving unit at the position corresponding to the coordinates of the electromagnetic wave receiving unit.

[0061] This embodiment records user information by setting a near-field communication storage module on the stylus pen, and realizes the interaction of user information when the stylus pen is close to the near-field communication reading module of the touch display device for recording by the touch display device, thereby achieving the purpose of rapid binding and registration between the stylus pen and the touch display device; at the same time, the stylus pen actively sends electromagnetic waves of a specified frequency band during use, and the touch display device determines the corresponding user based on the received electromagnetic wave frequency band, thereby realizing the distinction between handwritings of multiple people, and facilitating the organization and use of written records.

[0062] Multiple embodiments of the present disclosure are described in detail above, but the present disclosure is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications to the embodiments based on the concepts of the present disclosure, and these variations and modifications should all fall within the scope of protection required by the present disclosure.
