[0002] At present, with the rapid development of mobile communication technology, smart phones play an extremely important role in social activities. People rely on it for convenient and efficient social interaction, and information can be transmitted and updated at a very fast speed. However, traditional paper carriers for displaying personal information (such as paper business cards), as a way of social information exchange, have obvious defects in the information update link.

[0003] Once personal information changes (such as a promotion or a change in contact information), it is extremely troublesome to update the information on the paper carrier. Users need to re-plan the information content and then contact the printer for typesetting and printing. This process is both costly and time-consuming. From placing an order for printing to receiving the new information carrier, it usually takes some time. And during this waiting period, the old information is still being used, which can easily lead to inaccurate information, bringing many inconveniences to business negotiations and social interactions, and seriously affecting communication efficiency and social experience.

[0065] Embodiment 1

[0066] See Figure 1 , which is a schematic flowchart of a method for personalized image display of an electronic paper mobile phone case provided by an embodiment of the present invention, including:

[0067] S1. According to the template selection instruction sent by the terminal, search for a matching template file in the preset template library, and use the matching template file as the target template file; wherein, the template library includes several preset template files; the target template file includes a preset target template layout style and the corresponding target information filling rule;

[0068] Schematically, the user sends a template selection instruction through the terminal; after receiving the template selection instruction sent by the terminal, the server needs to search for a matching template file in the preset template library according to the user's template selection instruction.

[0069] In a preferred embodiment, the template names of the template files in the template library are different from each other; the target template file further includes a target template name.

[0070] Searching for a matching template file in the preset template library according to the template selection instruction sent by the terminal includes:

[0071] Analyze the template selection instruction to obtain the target template name selected by the terminal.

[0072] Set the target template name as the search keyword.

[0073] Perform a matching operation according to the search keyword and the template files in the template library, and when it is determined that the matching result of the matching operation is consistent, end the matching operation, and use the current template file for the matching operation as the matching template file.

[0074] Among them, the matching operation includes:

[0075] Judge whether the template name of the current template file for the matching operation is the same as the search keyword. If so, set the matching result as consistent; otherwise, set the matching result as inconsistent.

[0076] Specifically, assume that there are template files such as template file A, template file B, and template file C in the template library. The template name of template file A is "Creative Art Style Template", the template name of template file B is "Classical Elegant Style Template", and the template name of template file C is "Business Simple Style Template".

[0077] The user clicks and selects the option named "Business Simple Style Template" on the terminal. The server will parse out the template name "Business Simple Style Template" through the template selection instruction, and use "Business Simple Style Template" as the target template name, and then perform a matching operation.

[0078] First, after comparing the template name of template file A with the search keyword, the obtained matching result is inconsistent (because "Creative Art Style Template" is different from "Business Simple Style Template").

[0079] Similarly, after comparing the template name of template file B with the search keyword, the obtained matching result is also inconsistent.

[0080] After comparing the template name of template file C with the search keywords and obtaining a consistent matching result, the matching operation is terminated at this time, and template file C is used as the matching template file.

[0081] In a preferred embodiment, the configuration process of the template file includes:

[0082] Executing a software application by a processor and rendering a configuration interface of the template file on a display; wherein, the configuration interface includes a template selection area and a template file editing area; the template file editing area includes a layout style editing sub-area and a rule configuration sub-area; the layout style editing sub-area includes an initial layout style;

[0083] Responding to a selection operation on the template selection area to determine the template file to be edited;

[0084] Responding to a layout editing operation on the layout style editing sub-area, adjusting the layout elements in the initial layout style, and using the adjusted initial layout style as the template layout style of the template file to be edited; wherein, there is at least one area to be filled in the template layout style;

[0085] Responding to a rule configuration operation on the rule configuration sub-area to determine the filling rules that the areas to be filled in the template layout style should satisfy;

[0086] When it is determined that the configuration status of the template file editing area is saved, a template file is generated according to the template layout style of the template file editing area and the filling rules that the areas to be filled in the template layout style should satisfy;

[0087] See Figure 2 , which is a schematic diagram of the configuration interface provided by an embodiment of the present application;

[0088] Illustratively, taking the example of editing a template file with a template name of "Business Simple Style Template" to explain this embodiment;

[0089] Specifically, first, the user selects the template name "Business Simple Style Template" in the template selection area through the terminal, so that the server responds to the user's selection operation. At this time, both the layout style editing sub-area and the rule configuration sub-area are in an editable state; in the initial state, the layout style editing sub-area of the template file "Business Simple Style Template" is the initial layout style, and the user can adjust the layout elements in the initial layout style through layout editing operations;

[0090] In a preferred embodiment, the layout editing operations include an element addition operation, an element deletion operation, a position adjustment operation, and a size scaling operation;

[0091] Specifically, refer to Figure 3 , which is a schematic diagram of the interface of the layout style editing sub-region provided by an embodiment of the present application. The following combines Figure 3 to illustrate the layout style editing process of the "business minimalist style template":

[0092] (1) Element addition operation: Create a text box through the text function in the component library in Figure 3 , then input the words "Company Name", and set the font color to black and the font size to 30;

[0093] (2) Element deletion operation: Select the element to be deleted in the layout style editing sub-region, and click the "Delete" button to complete the element deletion;

[0094] (3) Position adjustment operation: If you need to adjust the position of the element "Company Name", find the "Information" section, which has data input boxes for "X-axis" and "Y-axis". The X-axis data controls the position of the element in the horizontal direction, and the Y-axis data controls the position of the element in the vertical direction. The user only needs to enter the desired value in the input box corresponding to the "X-axis" to change the position of the "Company Name" element in the horizontal direction; similarly, enter the corresponding value in the "Y-axis" input box to adjust its position in the vertical direction. For example, if the current position of the "Company Name" is too far to the left and you want to move it to the right by a certain distance, the user can appropriately increase the value of the "X-axis"; if you feel that the position is too high and you want to adjust it downwards, then decrease the value of the "Y-axis". In this way, the user can accurately modify the position of the "Company Name" element to meet the design requirements for the template layout and make the information display of the entire template more reasonable and beautiful;

[0095] (4) Size scaling operation: If the user feels that the size of the QR code in the template is too small, find the "Information" section, which has a parameter setting column for adjusting the size ("Width" and "Height" these two options); the user only needs to enter the value "80" in the "Width" input box and also enter the value "80" in the "Height" input box. By modifying these two values, the server will recalculate the display size of the QR code according to the set algorithm, so that its actual display size in the template becomes larger to meet the actual usage requirements;

[0096] It should be noted that the unit of these values can be pixels or the default size measurement unit of the server;

[0097] Thus, based on the layout editing operations entered by the user, the template layout style of the "business minimalist style template" is set;

[0098] Subsequently, it is necessary to set the rule configuration sub-region of the "Business Simple Style Template". The following describes the rule configuration process of the "Business Simple Style Template" in conjunction with Figure 3 :

[0099] As can be seen from Figure 3 , there are seven areas to be filled in the template layout style of the "Business Simple Style Template", namely "Name", "Position", "QR Code", "Phone Number", "Email Address", "Company Address", and "Company Name";

[0100] (1) For the area to be filled in "Name": Set as a required field, and limit the character length to between 2 and 10 Chinese characters; this can ensure that when generating an image, the user must fill in the name, and the name length conforms to the conventional specification, avoiding the situation that the name is missing or too long affecting the image display effect;

[0101] (2) For the area to be filled in "Position": Set as an optional field;

[0102] (3) For the area to be filled in "QR Code": The rule is set as a required field, and it must be in a valid format; the server will automatically perform format verification on the uploaded QR code through a preset algorithm to ensure that the QR code on the generated image can be used normally, facilitating others to obtain relevant information by scanning the code;

[0103] (4) For the area to be filled in "Phone Number": Set as a required field, and only valid mobile phone number formats can be filled; the server will automatically verify whether the input content conforms to the regular expression of the mobile phone number to ensure the accuracy and validity of the phone number, facilitating others to contact;

[0104] (5) For the area to be filled in "Email Address": Set as a required field, and it must conform to the standard email address format, such as containing the "@" symbol;

[0105] (6) For the area to be filled in "Company Address": Set as a required field, and the character length is limited within N characters;

[0106] (7) For the area to be filled in "Company Name": Set as a required field, and the character length is limited within N characters;

[0107] When the user completes all these rule settings and clicks the save button, the server can generate the final template file of the "Business Simple Style Template" according to the template layout style of the "Business Simple Style Template" and the set filling rules;

[0108] Specifically, the template library includes several pre-set template files. For example, there is a "Business Elite Template" suitable for office workers, and its template layout is presented in a simple table form. Information such as name, position, phone number, email address, company address, and company name each occupy a column, and the font is a simple bold font, highlighting professionalism and stability. There is also a "Creative Inspiration Template" suitable for creative workers. The layout of the creative inspiration template breaks the routine, and the information is arranged in irregular graphics. The text uses artistic fonts and is paired with bright and lively colors such as orange and yellow, fully demonstrating personality and creativity.

[0109] S2. Obtain the information to be filled from the terminal according to the target template layout style and the target information filling rule;

[0110] In a preferred embodiment, the obtaining the information to be filled from the terminal according to the target template layout style and the target information filling rule includes:

[0111] Obtain the original image uploaded by the terminal; wherein, the original image includes specific information to be displayed on the e-paper mobile phone case; the position information of the specific information in the original image matches the position information of the target area to be filled in the target template layout style under a preset coordinate system;

[0112] Preprocess the original image to obtain a preprocessed image;

[0113] Call a preset OCR interface to enable the OCR interface to extract the specific information from the preprocessed image;

[0114] Use the specific information as the information to be filled;

[0115] Illustratively, taking the "Business Simple Style Template" as an example, the process of obtaining the information to be filled from the user terminal is described:

[0116] Specifically, first, the original image needs to be obtained: The user selects a file on the terminal that needs to be used to generate the display content of the e-paper mobile phone case and uploads it. The server obtains the original image uploaded by the user terminal. The server has preset a coordinate system, and the position information of the specific information in the original image should have a proportional relationship with the position information of the target area to be filled in the "Business Simple Style Template" target template layout style under this preset coordinate system;

[0117] Subsequently, for the convenience of subsequent information extraction, the server preprocesses the acquired original image; this step includes grayscale processing, noise reduction, image enhancement, and equal-proportion magnification / minification. Since the size of the original image may not be consistent with the size of the target template layout style, in order to ensure that the position information of specific information in the original image corresponds to the position information of the target area to be filled in the target template layout style, it is necessary to perform a size correspondence operation between the original image and the target template layout style of the target template file "Business Simple Style Template"; the server calculates an appropriate scaling factor according to the size of the target template layout style and the preset proportional rule, and performs equal-proportion magnification or minification on the image after grayscale processing, noise reduction, and image enhancement;

[0118] Immediately afterwards, the server calls a preset OCR (Optical Character Recognition) interface; for the text part in the preprocessed image, the OCR interface will recognize and convert it into editable text information. For each piece of information to be filled in the "Business Simple Style Template", such as "Name", "Position", "Phone Number", etc., the OCR interface will accurately extract the corresponding specific information from the preprocessed image according to the correspondence between the position of the text in the preprocessed image and the position information of the target area to be filled in the target template layout style;

[0119] S3. According to the target information filling rule, fill the information to be filled into the target area to be filled in the target template layout style to obtain the target template after filling;

[0120] Specifically, the specific information extracted by the OCR interface will be used by the server as the information to be filled; these information to be filled will be filled into the corresponding target areas to be filled in the target template layout style according to the previously set target information filling rule of the "Business Simple Style Template", thus completing the process of obtaining information from the terminal and preparing to fill it into the template, and making preparations for generating the target image for e-paper mobile phone case display subsequently.

[0121] S4. Call a preset image processing software so that the image processing software converts the filled target template into a corresponding target image according to the preset image configuration parameters;

[0122] Schematically, the image configuration parameters include image format, color mode, and resolution setting;

[0123] It should be noted that the image processing software can be selected as a vector graphics editing software or other software suitable for making images for e-paper display;

[0124] Specifically, the image format is selected as the SVG (Scalable Vector Graphics) format. Images in this format are composed of vector graphics and will not be distorted whether magnified or reduced, making them suitable for display on e-paper.

[0125] See Figure 4 , after the filled target template is transmitted to the image processing software, the image processing software will perform image processing according to these preset image configuration parameters, thereby converting the filled target template into a target image suitable for e-paper.

[0126] S5. Send the target image to the terminal so that the terminal, according to the pre-configured communication connection parameters, transmits the target image to the corresponding e-paper mobile phone case, enabling the e-paper mobile phone case to display the target image through the built-in e-paper.

[0127] In a preferred embodiment, a first NFC communication module is pre-configured inside the terminal; a second NFC communication module is pre-configured inside the e-paper mobile phone case; the communication connection parameters are NFC communication connection parameters; the first NFC communication module of the terminal and the second NFC communication module of the e-paper mobile phone case are pre-connected through the NFC communication connection parameters to establish an NFC channel connection.

[0128] The step of sending the target image to the terminal so that the terminal, according to the pre-configured communication connection parameters, transmits the target image to the corresponding e-paper mobile phone case, enabling the e-paper mobile phone case to display the target image through the built-in e-paper, includes:

[0129] Send the target image to the terminal so that the terminal, through the established NFC channel connection, transmits the received target image to the e-paper mobile phone case, enabling the e-paper mobile phone case to display the target image through the built-in e-paper.

[0130] Schematically, after obtaining the target image suitable for e-paper, next, the target image needs to be transmitted to the e-paper mobile phone case through the user terminal and displayed.

[0131] Specifically, a first NFC (Near Field Communication) communication module is pre-configured inside the terminal, and a second NFC communication module is pre-configured inside the e-paper mobile phone case, and the communication connection parameters are NFC communication connection parameters.

[0132] In the preliminary preparation stage, the first NFC communication module of the terminal and the second NFC communication module of the e-paper mobile phone case have been pre-connected through the NFC communication connection parameters to establish an NFC channel connection.
