Based on the same inventive concept, the present disclosure exemplarily provides a handwriting tablet 100, and Figures 5 to 7 respectively show three-dimensional views of a handwriting tablet according to an exemplary embodiment at different angles. Specifically, the handwriting tablet 100 of the present disclosure includes a display panel 10, a housing 20, a wireless network signal transceiver, a storage module, and a synchronous display module.

The display panel 10 is used to receive an input signal and display information corresponding to the input signal. The input signal may be, for example, a signal input to the surface of the display panel 10 or an input signal received through a wiring connected to the display panel 10 .

For example, a fingertip or a writing pen may write or draw on the display panel 10 to input a signal to the display panel 10. At this time, as the fingertip or the writing pen moves on the display panel 10, the movement track of the fingertip or the writing pen is displayed on the display panel 10. The thickness of the line displayed on the display panel 10 varies according to the force applied. When the force applied is large, the displayed line is thick, and when the force applied is relatively small, the displayed line is relatively thin.

For another example, the display panel 10 may be connected to the synchronous display module through wiring, and display information corresponding to the input signal transmitted by the synchronous display module to the display panel 10. The information includes images or text.

For another example, the display panel 10 may also display information received through a wireless network signal transceiver, but is not limited thereto.

The present disclosure preferably uses a liquid crystal panel as the material of the display panel 10. The liquid crystal panel has the advantages of high resolution, long life and the ability to display painting information in color. However, the present disclosure does not limit the material of the display panel 10, and it can also be an electronic ink screen.

As shown in FIG. 5 to FIG. 7 , the display panel 10 is disposed in the housing 20 . The housing 20 surrounds the display panel 10 at least from four sides, so as to protect the display panel 10 .

In addition, a wireless network signal transceiver, a storage module, and a synchronous display module may be disposed inside the housing 20 .

A pen slot 70 for placing a writing pen 40 described later may also be provided on the outside of the housing 20. The pen slot 70 may be provided at the rear of the housing 20, or at a side or front of the housing 20. When the pen slot 70 is provided at the rear of the housing 20, the front of the display panel 10 serving as the display surface may not be occupied, thereby ensuring the beauty of the product and the size of the display surface.

In addition, a wall hanging structure 80 for mounting the handwriting board 100 on a wall may be provided at the rear or side of the housing 20. In this embodiment, the wall hanging structure 80 may be formed as a hanging groove structure. However, it is not limited thereto, and a wall suction structure may be formed instead of the wall hanging structure 80.

In addition, as shown in FIG6 , various buttons 60 may be provided on the side of the housing 20 , and the buttons may include a temperature button, a humidity button, a volume adjustment button, a switch button, a display brightness adjustment button, etc., through which the handwriting board 100 is controlled. In addition to the buttons exemplified above, other buttons may be provided as required, and the present disclosure does not impose any special restrictions on this. In addition, the buttons may be formed as mechanical buttons as shown in FIG6 , or may be formed as touch buttons.

The wireless network signal transceiver is disposed inside the housing 20 . Through the wireless network signal transceiver, the handwriting board 100 can receive and send wireless network signals with an external mobile terminal or the cloud.

For example, the handwriting tablet 100 of the present disclosure can be wirelessly connected to a mobile terminal through a wireless network signal transceiver to send and receive network signals to each other. The mobile terminal can be a mobile phone 200 or a tablet, etc., but is not limited thereto. In the following description, the mobile phone 200 is used as an example of a mobile terminal for description.

On this basis, the handwriting board 100 of the present disclosure also includes a storage module, which can store the works drawn on the handwriting board 100 each time to form a library of historical paintings. In addition, these historical paintings can be selectively scrolled and displayed in the handwriting board 100. However, as shown in Figure 11, the handwriting board 100 is wirelessly connected to the cloud 300 through a wireless network signal transceiver, so that the historical paintings are stored in the cloud 300, and the mobile phone 200 can directly read the historical paintings in the handwriting board 100 from the cloud 300 and display them on the mobile phone 200. Furthermore, the historical paintings can also be directly transmitted to the mobile phone 200 for storage, and displayed on the mobile phone 200. Compared with using tools such as USB to obtain historical paintings, this method greatly improves the acquisition efficiency and improves the user's convenience.

On this basis, the handwriting board 100 of the present disclosure further includes a synchronous display module. The synchronous display module is disposed inside the housing 20. The synchronous display module can transmit and receive signals through the wireless network signal transceiver. When the synchronous display module receives a synchronous display instruction, information matching the synchronous display instruction is displayed on the display panel. The synchronous display module is used to synchronously display information on the handwriting board 100 and/or the mobile phone 200 on the handwriting board 100 and the mobile phone 200.

Depending on the display mode, the synchronous display instructions may include: display instructions of the display panel (hereinafter referred to as the first instruction), display instructions of the mobile terminal matching the handwriting board (hereinafter referred to as the second instruction), and dual-screen display instructions of the display panel and the mobile terminal (hereinafter referred to as the third instruction).

Specifically, when the synchronous display instruction is the first instruction, the same picture as the picture currently displayed on the display panel (referred to as the first picture) is displayed on the display panel; when the synchronous display instruction is the second instruction, the same picture as the picture currently displayed on the mobile terminal is displayed on the display panel (referred to as the second picture); when the synchronous display instruction is the third instruction, the same picture as the picture currently displayed on the display panel and the same picture as the picture currently displayed on the mobile terminal are displayed on the display panel on a dual screen at the same time (referred to as the dual-screen picture). That is, according to the synchronous display instruction, one of the first picture, the second picture or the dual-screen picture can be displayed on the display panel.

As a preferred embodiment of the present disclosure, the handwriting board and the mobile terminal perform real-time synchronous display through the wireless network signal transceiver. In other words, not only can one of the above pictures be displayed on the handwriting board, but also one of the above pictures can be synchronously displayed on the mobile terminal.

In an application scenario, taking the wireless connection between the handwriting tablet 100 and the mobile phone 200 as an example, the mobile phone 200 can send one of the above three instructions to the synchronous display module of the handwriting tablet 100.

For example, as shown in FIG8 , when the mobile phone 200 sends a first instruction to the synchronous display module of the handwriting board 100, the child can start writing on the handwriting board 100 at home, and the display panel 10 displays the child's writing process. At the same time, the content currently displayed on the handwriting board 100 is also synchronously displayed on the mobile phone 200. That is, the handwriting board 100 and the mobile phone 200 perform real-time synchronous display.

For another example, as shown in FIG9 , when the mobile phone 200 sends a second instruction to the synchronous display module of the handwriting board 100, the parent or teacher starts writing on the mobile phone 200, and the display panel 10 displays the writing process of the parent or teacher. At the same time, the content currently displayed in the mobile phone 200 is also synchronously displayed on the mobile phone 200. That is, the handwriting board 100 and the mobile phone 200 perform real-time synchronous display.

For another example, when the mobile phone 200 sends a third instruction to the synchronous display module of the handwriting board 100, a dual screen appears on the display panel 10, and the parents or teachers and the children can write on the mobile phone 200 and the handwriting board 100 at the same time, respectively, and the dual screens of the display panel 10 respectively display the process of the parents' writing and the process of the children's writing, so that they can see not only their own writing process, but also the process of the other party's writing. As a result, the handwriting board 100 of the present disclosure is wirelessly connected to the mobile phone 200, and can realize the bidirectional synchronous writing and drawing functions, meeting the needs of synchronous writing and drawing in different places. That is, the screens of both are synchronously displayed on the mobile phone 200 and the handwriting board 100. That is, the handwriting board 100 and the mobile phone 200 are displayed synchronously in real time.

In addition, in one embodiment, the handwriting tablet 100 further includes a matching module, which matches the handwriting tablet 100 and the mobile terminal through the wireless network signal transceiver. For example, after the handwriting tablet 100 and the mobile phone 200 are matched through the wireless network signal transceiver, the two can not only write or draw synchronously as described above, but also transmit and receive each other's stored information. Of course, when the handwriting tablet 100 needs to transmit data or write or draw synchronously with other mobile terminals, it can be matched through the matching module.

In one embodiment, the handwriting board 100 further includes a call module, which is disposed in the housing, and the call module establishes a voice call with the mobile terminal through the wireless network signal transceiver. As an embodiment of the call module, the call module may include a speaker and a microphone, but is not limited thereto.

In one application scenario, when a teacher wants to provide drawing guidance to students in a remote location, voice communication may be required during the process of synchronous drawing and displaying through the mobile phone 200 and the handwriting board 100. However, if the child is too young and does not have a mobile phone, voice communication is not possible. However, the present disclosure can directly establish a voice call with the teacher's mobile phone 200 by setting a call module on the handwriting board 100, thereby greatly improving communication efficiency and providing convenience for remote guidance and teaching.

In one embodiment, the handwriting tablet 100 further includes a temperature and humidity monitoring module 30, which is disposed inside the housing 20. The display panel 10 displays at least one of the temperature and humidity monitored by the temperature and humidity monitoring module according to the received input signal. The temperature and humidity monitoring module may include a temperature sensor and a humidity sensor. When the user presses the temperature button or the humidity button, the temperature information or humidity information collected by the temperature sensor or the humidity sensor can be displayed on the display panel 10. Such input signals include not only signals input through the temperature button or the humidity button disposed on the handwriting tablet 100, but also signals input from a mobile terminal matched and connected to the handwriting tablet 100. The specific process will be described in detail below.

In one embodiment, the display panel displays information corresponding to the remote display control command according to the remote display control command received from the mobile terminal. For example, the mobile phone 200 may be provided with an application matching the handwriting board 100, and the application may have various functional modules, as shown in FIG10 , and the application may include display options such as time calendar, electronic photo album, temperature and humidity, and memo reminders. When the user selects one of the options, the corresponding remote display control command is sent to the handwriting board, so that the information indicated by the option is displayed on the display panel.

For example, when the user selects the time calendar option, the network time is displayed on the display panel 10 of the handwriting tablet 100. At this time, the unused handwriting tablet 100 is hung on the wall and used as an electronic watch to display time calendar information.

For another example, the historical paintings drawn on the handwriting board 100 can be stored in the memory of the handwriting board 100, or stored in the cloud 300 through a wireless network. As shown in FIG12, when the user selects the electronic album option, the mobile phone 200 can read and filter the historical paintings from the memory of the handwriting board 100 or through the cloud 300, edit and display the play time, etc., make an electronic album, and display the electronic album through the display panel 10 of the handwriting board 100. Not only can the historical paintings be animated on the mobile phone, but the handwriting board 100 can also be hung on the wall, and the display panel 10 of the handwriting board 100 can be controlled by the mobile terminal to display the historical paintings for appreciation.

For another example, as shown in Figure 13, when the user selects the temperature and humidity option, the mobile phone 200 sends a temperature and humidity display command signal to the handwriting board 100, and displays at least one of the temperature and humidity information monitored by the temperature and humidity monitoring module on the display panel 10. As a result, parents outside can obtain the temperature information and/or humidity information of the environment where the handwriting board is located (for example, home) through the mobile phone 200, and take corresponding measures as needed.

For another example, when the user selects the memo reminder option, the mobile phone 200 sends a memo reminder instruction to the handwriting board 100, and the memo reminder information is displayed on the display panel 10. For example, when parents need to work overtime, they can write "overtime today" on the mobile phone 200, and then send a memo reminder instruction to the handwriting board 100, and the display panel 10 of the handwriting board 100 will display "overtime today" based on the memo reminder instruction, thereby informing the children at home through the handwriting board 100 that the parents are working overtime.

In one embodiment, the handwriting tablet further includes a remote start button, which receives a start instruction or a shutdown instruction from the mobile terminal through a wireless network signal transceiver to start or shut down the handwriting tablet. For example, when you forget to turn off the handwriting tablet when you go out, use the mobile terminal to remotely shut down the handwriting tablet to prevent the handwriting tablet from being in a normally open state and wasting electricity. For another example, when you need to send the memo reminder described above to your home, the mobile phone 200 sends a start instruction to the handwriting tablet 100 to turn on the handwriting tablet 100, and then operates the above "memo reminder" operation. This remote control of the handwriting tablet through a mobile terminal can form a smart home network with the handwriting tablet and other homes.

In one embodiment, the handwriting tablet 100 further includes a writing pen 40. When the writing pen 40 contacts the display panel 10 and moves, the moving track of the writing pen is displayed on the display panel. Drawing on the display panel 10 with the writing pen 40 greatly improves the drawing accuracy compared with finger drawing. In order to prevent the writing pen 40 from being lost, the writing pen 40 can be placed in the pen slot 70 described above when not in use, but it is not limited thereto. The writing pen 40 can also be adsorbed to the housing 20 of the handwriting tablet 100 through a magnetic attraction structure.

In addition, the handwriting tablet 100 further includes a rechargeable battery, and the handwriting tablet 100 is charged through the charging port 50 , but the present disclosure is not limited thereto, and other charging devices such as dry batteries may also be used.

The handwriting tablet provided according to the embodiments of the present disclosure can perform synchronous writing and drawing with other terminal devices such as mobile phones, can have voice calls with other terminal devices such as mobile phones, can store historical paintings and selectively scroll and display these historical paintings in the handwriting tablet, can be remotely controlled through other terminal devices such as mobile phones, and can form a smart home network with other homes.
