[0030] Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] This utility model embodiment provides a handwriting device with printing function.

[0033] Please see Figures 1-4 The handwriting device with printing function includes an electromagnetic pen 100 and a handwriting device 200.

[0034] The electromagnetic pen 100 is used for writing on the handwriting device 200; it should be noted that the electromagnetic pen 100 has basic functions, including a pen tip and an induction coil.

[0035] The handwriting device 200 includes a cholesteric liquid crystal display panel 201, an electromagnetic induction antenna plate 220, a printing mechanism 230, and a control component (not shown). Specifically, the cholesteric liquid crystal display panel 201 and the electromagnetic induction antenna plate 220 are arranged vertically. The cholesteric liquid crystal display panel 201, the electromagnetic induction antenna plate 220, and the printing mechanism 230 are all electrically connected to the control component. The cholesteric liquid crystal display panel 201 is used to display the movement trajectory of the electromagnetic pen 100 during the writing process. The movement trajectory displayed by the cholesteric liquid crystal display panel 201 can be directly seen by the user. The writing with the electromagnetic pen 100 can be handwriting, drawing, etc. The electromagnetic induction antenna plate 220 is used to sense the movement trajectory of the electromagnetic pen 100 during the writing process. It should be noted that the movement trajectory sensed by the electromagnetic induction antenna plate 220 is the same as the movement trajectory displayed by the cholesteric liquid crystal display panel 201. The control component can obtain trajectory information from the electromagnetic induction antenna plate 220 and control the printing mechanism 230 to print the trajectory information onto paper. The control component can apply an erasure voltage to the cholesteric liquid crystal display panel 201 and can also clear the trajectory information.

[0036] It should be noted that when printing trajectory information, i.e., when a printing operation is required, the control component can be equipped with a mechanical print button 201 to control the printing mechanism 230 to print the trajectory information onto the paper. Pressing the print button 201 controls the printing mechanism 230 to print the trajectory information onto the paper. Alternatively, a corresponding touch button can be provided, or a predetermined program can be set. For example, if trajectory information is formed and no update occurs after a first predetermined time, the control component performs the printing operation without requiring active printing. Similarly, when erasing the movement trajectory of the cholesteric phase liquid crystal display panel 201, i.e., when an erasure operation is required, a mechanical erase button 202 can be provided. Pressing the erase button... At time 202, the control component applies an erasure voltage to the cholesteric phase liquid crystal display panel 201, resetting the cholesteric phase liquid crystal display panel 201, that is, clearing the traces on the cholesteric phase liquid crystal display panel 201. Of course, a corresponding touch button can also be provided, or a predetermined program can be set to achieve this. For example, when trace information is formed and no trace information is updated after a second predetermined time, an erasure operation is performed. When clearing trace information, that is, when a clearing operation needs to be performed, a mechanical clearing button can be provided. That is, when the clearing button is pressed, the control component clears the trace information. Of course, a corresponding touch button can also be provided, or a predetermined program can be set to achieve this. For example, when trace information is formed and no trace information is updated after a third predetermined time, a clearing operation is performed.

[0037] Furthermore, it should be noted that the handwriting device 200 integrates a cholesteric liquid crystal display panel 201, an electromagnetic induction antenna panel 220, a printing mechanism 230, and a control component. Specifically, the cholesteric liquid crystal display panel 201, the electromagnetic induction antenna panel 220, the printing mechanism 230, and the control component are partial structures of the handwriting device 200.

[0038] Based on the structural design of this utility model, the handwriting device with printing function adds printing functionality to the handwriting device 200, which is not limited to handwriting input. Thus, during use, in addition to displaying the movement trajectory using the cholesteric liquid crystal display panel 201, the handwriting device 200 can also use a printer to print the trajectory information corresponding to the movement trajectory onto paper. Further writing can be done on the paper to realize the writing operation of the cholesteric liquid crystal display panel 201, such as adding color with colored pens, etc. The handwriting device with printing function has a more diversified way of use.

[0039] In addition, it should be noted that the erasure operation can be a full erase or a partial erase. When the handwriting device 200 is small, such as a children's writing tablet, a full erase is more suitable, while when the handwriting device 200 is large, such as a commercial writing tablet, a partial erase is more suitable. To achieve partial erase, the control component can first be put into partial erase mode, and then the participatory position can be obtained by using the electromagnetic pen 100 in conjunction with the electromagnetic induction antenna board 220.

[0040] In this embodiment of the invention, the control component erases the trajectory information simultaneously when applying the erasure voltage. When erasing the movement trajectory displayed on the cholesteric liquid crystal display panel 201, the control component deletes the trajectory information as well. Thus, the movement trajectory displayed on the cholesteric liquid crystal display panel 201 corresponds to the trajectory information. By observing the movement trajectory displayed on the cholesteric liquid crystal display panel 201, the printed content can be determined, providing a WYSIWYG experience and improving the user experience.

[0041] Furthermore, in practice, the erase button 202 and the clear button can be combined into a single erase button 202.

[0042] Please see Figure 4 In this embodiment of the utility model, the cholesteric phase liquid crystal display panel 201 is a semi-transparent cholesteric phase liquid crystal display panel or a semi-transparent color volume cholesteric phase liquid crystal display panel.

[0043] A cholesteric liquid crystal display panel 201 and an electromagnetic induction antenna panel 220 are spaced apart and a tracing cavity 240 is formed therein. The tracing cavity 240 has an insertion port located on the side of the handwriting device 200. Specifically, in this embodiment, the insertion port is located on the right side of the handwriting device 200.

[0044] Based on this, it can be used with tracing sheets printed with graphics or text. Specifically, during use, the tracing sheet printed with graphics or text is inserted into the tracing cavity 240 through the insertion port. The user can observe the graphics or text on the tracing sheet through the cholesteric liquid crystal display panel 201, and then tracing it.

[0045] As can be seen from the above, based on this structural design, the handwriting device with printing function has added a tracing function, further increasing the diversity of its usage.

[0046] Specifically, the distance between the cholesteric liquid crystal display panel 201 and the electromagnetic induction antenna plate 220 is 0.2-1.2mm. First, this distance allows for the placement of a copying sheet of a certain thickness in the copying cavity 240, increasing the range of materials that can be selected for the copying sheet, reducing the cost of the cholesteric liquid crystal display panel 201 components, and also reducing the cost of using handwriting devices with printing functions. Second, this distance also ensures that the electromagnetic pen 100 maintains good magnetic induction with the electromagnetic induction antenna plate 220 during writing.

[0047] Please see Figure 4 In this embodiment of the invention, the cholesteric liquid crystal display panel 201 includes a translucent cholesteric liquid crystal display film 211 and a transparent support plate 212, which are disposed vertically. The support plate 212 may be made of acrylic sheet.

[0048] Since the cholesteric liquid crystal display panel 201 and the electromagnetic induction antenna plate 220 are spaced apart, the cholesteric liquid crystal display panel 201 itself needs to have a certain mechanical strength. Based on this, the overall mechanical strength of the cholesteric liquid crystal display panel 201 can be controlled by the thickness of the support plate 212, resulting in a simple structure and low cost.

[0049] In this embodiment of the invention, the handwriting device 200 further includes at least one light-emitting element 250. Each light-emitting element 250 is electrically connected to the control component and is disposed on the periphery of the support plate 212. Each light-emitting element 250 is used to illuminate the support plate 212, and the light from each light-emitting element 250 is guided by the support plate 212 to illuminate the copying cavity 240. The light-emitting element 250 can be an LED chip.

[0050] Since the cholesteric liquid crystal display panel 201 is a semi-transparent cholesteric liquid crystal display panel 201, the light reaching the tracing film is reduced. When the tracing film is viewed through the cholesteric liquid crystal display panel 201, the tracing film will appear darker and harder to see.

[0051] Based on this structural design, the light from the light-emitting body 250 is guided by the support plate 212 and shines into the tracing cavity 240, increasing the amount of light shining on the tracing sheet. At this time, when the tracing sheet is observed through the cholesteric liquid crystal display panel 201, the tracing sheet will not appear too dark, making it easier to see the tracing sheet clearly. Furthermore, based on this structural design, the handwriting device with printing function can also be used in a dark environment.

[0052] In this embodiment of the invention, the control component can obtain trajectory information from the electromagnetic induction antenna board 220 and save it as backup information.

[0053] The control component can control the printing mechanism 230 to print the trajectory information onto the paper.

[0054] Therefore, before performing the erasure operation, the trajectory information can be saved as backup information, so that after the erasure operation, the previous trajectory information can also be printed onto the paper.

[0055] It should be noted that when saving trajectory information as backup information, that is, when a save operation is required, the control component can be equipped with a mechanical save button 203 to save the trajectory information as backup information. That is, when the save button 203 is pressed, the control component saves the trajectory information as backup information. Of course, a corresponding touch button can also be provided, or a predetermined program can be set to achieve this. For example, when trajectory information is formed and there is no update to the trajectory information after a first predetermined time, the control component performs a save operation without the need for an active save operation.

[0056] It should also be noted that, as mentioned before, the trajectory information corresponds to the movement trajectory of the cholesteric phase liquid crystal display panel 201. There can be multiple backup information, and each backup information is usually different. The backup information only corresponds to the movement trajectory of the cholesteric phase liquid crystal display panel 201 when it is saved. The backup information can be stored directly using the control component, or a storage interface 204 can be set to save it to an external storage device, such as an SD card or a USB flash drive.

[0057] In this embodiment of the invention, the control component includes a wireless connection module that can wirelessly connect to an external device. The wireless connection module is used to transmit data between the control component and the external device. The control component can obtain external information from the external device through the wireless connection module and control the printing mechanism 230 to print the external information onto paper.

[0058] In this way, the handwriting device with printing function can be connected to external devices, such as mobile phones, tablets, laptops, etc., through a wireless connection module. The external devices can provide the handwriting device with printing function with rich external information, so that the information that the printing mechanism 230 can print is not limited to the writing of the electromagnetic pen 100, and further increases the diversity of usage methods.

[0059] It should be noted that when a handwriting device with printing function is connected to an external device via a wireless connection module, printing, erasing, and saving operations can also be triggered by the external device. For example, a matching APP can be set up on a mobile phone to trigger printing, erasing, and saving operations. The APP can also transmit track information and backup information to the external device.

[0060] It should also be noted that the printing mechanism 230 can print in black and white or in color.

[0061] In this embodiment of the invention, the handwriting device 200 further includes a speaker, which is electrically connected to the control component.

[0062] Based on this, relevant information can be broadcast through a speaker, such as indicating low battery or informing users of the status of an operation.

[0063] Furthermore, in this embodiment of the invention, the control component is capable of recognizing the content of the trajectory information. Based on this, combined with a speaker and external devices, learning operations can be performed. For example, users can answer questions by writing their answers onto the handwriting device 200 using the electromagnetic pen 100. The control component recognizes the content and broadcasts it accordingly based on its correctness. This further increases the versatility of usage.

[0064] In this embodiment of the utility model, the handwriting device 200 also includes a camera, which is electrically connected to the control component and can acquire image information by taking pictures;

[0065] The control component can control the printing mechanism 230 to print image information onto paper.

[0066] Based on this, the handwriting device 200 has been given a photo printing function, which further increases the diversity of its usage.

[0067] Please see Figures 2-3 In this embodiment of the utility model, the printing mechanism 230 is located below the electromagnetic induction antenna plate 220 and below the handwriting device 200 on the rear side.

[0068] When the handwriting device 200 is placed on the table, the cholesteric liquid crystal display panel 201 is tilted forward based on the position of the printing mechanism 230, making it easier for the user to use.

[0069] Please see Figure 1 In this embodiment of the invention, the handwriting device 200 is provided with a handle for easy carrying by the user. The handwriting device 200 has a pen slot 205 for placing the electromagnetic pen 100, which facilitates storage of the electromagnetic pen 100.

[0070] Please see Figure 2 In this embodiment of the utility model, the handwriting device 200 also includes a rechargeable battery and a charging interface 206, both of which are electrically connected to the control component.

[0071] Please see Figure 2 In this embodiment of the utility model, the handwriting device 200 also includes an indicator light 207 and a switch 208. The indicator light 207 and the switch 208 are both electrically connected to the control component. The indicator light 207 indicates the working status of the handwriting device 200 by the light color and flashing frequency, and the switch 208 is used to activate the control component.

[0072] In this embodiment of the invention, the handwriting device 200 also includes a display screen, which is used to display various information of the handwriting device 200, including the status of stored information, battery information, whether it is in partial erasure mode, etc.

[0073] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
