[0033] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature and not restrictive.

[0034] Those skilled in the art of the present technology can understand that, unless otherwise defined, all terms used herein (including technical terms and scientific terms) have the same meaning as the general understanding of those of ordinary skill in the art to which this application belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless specifically defined as here.

[0035] The inventors of the present application found in their research that since the passive electronic ink screen has no built-in battery or external power supply, it can only provide current for the passive electronic ink screen through electromagnetic induction of the wireless communication module of an external device (such as a mobile phone), and then realize the writing of content and the refreshing of the screen image, that is, screen refreshing. The functions of the wireless communication modules of most mobile phones on the market are not powerful enough, and the power of the mobile phone itself is not large enough, especially for some old models of mobile phones, resulting in very weak electromagnetic induction current. It is necessary to perform screen refreshing at relatively precise screen refreshing positions to meet the screen refreshing requirements. If it is not accurate enough, the current will become even weaker and it will be impossible to perform screen refreshing.

[0036] At the same time, based on some market demands, the passive electronic ink screen has a tendency to develop towards larger sizes. For a large-sized passive electronic ink screen, when using a mobile phone to perform screen refreshing, the screen refreshing position is very likely to deviate and it will be impossible to perform screen refreshing.

[0037] The following uses specific embodiments to detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems.

[0038] The embodiment of the present application provides a method for refreshing the screen of an electronic ink screen, which can be applied to terminal devices, such as mobile phones, tablets, etc. As Figure 1 shown, the method includes:

[0039] S101, determine whether there is historical record information of successful screen refreshing; if so, execute step S102; if not, execute step S103 or step S104.

[0040] The historical record information includes screen refreshing position information, such as the center coordinates, boundary coordinates, etc. of the area where the screen refreshing is successful. The screen refreshing position information of successful screen refreshing can be queried in the screen refreshing database. If the screen refreshing position information of successful screen refreshing can be queried, it can be determined that there is historical record information of successful screen refreshing. If the screen refreshing position information of successful screen refreshing cannot be queried, it can be determined that there is no historical record information of successful screen refreshing.

[0041] The historical record information may also include information such as the screen refreshing time, the time used for screen refreshing, and the model of the terminal device for screen refreshing. In one example, it can be determined whether there is historical record information of the most recent successful screen refreshing or historical record information of the successful screen refreshing with the shortest time used for screen refreshing.

[0042] S102. Output a screen swiping prompt message according to the screen swiping position information in the historical record information.

[0043] The screen swiping prompt message can be output according to the screen swiping position information in the most recent historical record information (i.e., the historical record information of the most recent successful screen swiping), and the most recent historical record information can be found according to the recorded screen swiping time; or the screen swiping prompt message can be output according to the historical record information with the shortest screen swiping time (the historical record information of the successful screen swiping with the shortest screen swiping time), and the historical record information with the shortest screen swiping time can be found according to the recorded screen swiping time.

[0044] The screen swiping prompt message can be an image of a prompt line at the screen swiping position. In this step, an image of the prompt line can be generated according to the screen swiping position information in the most recent historical record information or the historical record information with the shortest screen swiping time, and the image of the prompt line is output.

[0045] S103. Output a screen swiping prompt message according to the position information of the first wireless communication module and the position information of the second wireless communication module.

[0046] The first wireless communication module is the wireless communication module in the current terminal device, and the second wireless communication module is the wireless communication module in the electronic ink screen to be screen swiped.

[0047] The first wireless communication module and the second wireless communication module can be NFC (Near Field Communication) modules.

[0048] In this step, an image of a prompt line at the screen swiping position can be generated according to the position information of the first wireless communication module and the position information of the second wireless communication module as the screen swiping prompt message.

[0049] S104. Output a screen swiping prompt message according to the candidate screen swiping positions.

[0050] The screen swiping prompt message can include at least one of image information and text information. The image information can be an image of a prompt line at the screen swiping position, and the text information can prompt the user how to place the text content of the electronic ink screen.

[0051] In the embodiments of the present application, the electronic ink screen can output the screen swiping prompt message in multiple ways, including outputting the screen swiping prompt message according to the screen swiping position information in the most recent historical record information, outputting the screen swiping prompt message according to the position information of the first wireless communication module and the position information of the second wireless communication module, and outputting the screen swiping prompt message according to the candidate screen swiping positions, so as to help the user quickly find a better screen swiping position for screen swiping and solve the problem of difficult screen swiping of the passive electronic ink screen.

[0052] Optionally, after outputting the screen flashing prompt message, the status of successful and failed screen flashing can be monitored. In the case of successful screen flashing, the screen flashing position information of the current successful screen flashing can be recorded, for example, stored in a screen flashing database for query during subsequent screen flashing. In the case of failed screen flashing, the above step S103 or step S104 can be executed to output the screen flashing prompt message in other ways.

[0053] Optionally, as Figure 2 shown, in step S103, outputting the screen flashing prompt message according to the position information of the first wireless communication module and the position information of the second wireless communication module may include steps S201 - S204:

[0054] S201, obtain the first position information of the first wireless communication module in the screen of the current terminal device.

[0055] In an optional implementation manner, the first position information of the first wireless communication module in the screen of the current terminal device can be obtained in the following way: obtain an image of the terminal device containing the identification information of the first wireless communication module, and determine the position of the first wireless communication module in the screen of the current terminal device according to the position of the identification information of the first wireless communication module in the terminal device image, so as to obtain the first position information.

[0056] The identification information of the first wireless communication module in the current terminal device can be recognized from the image of the current terminal device, and the image of the current terminal device can be obtained through any one of channels such as the official website of the current terminal device, search engines, etc.

[0057] For terminal devices in the market with wireless communication modules such as NFC modules, the identification information of the NFC module is usually made public. According to the model of a certain terminal device, an image of the terminal device with the identification information of the NFC module can be obtained from channels such as the official website and search engines, and the position of the NFC module in the screen of the terminal device can be visually recognized from the image.

[0058] Figure 3 shows an image of a certain model of mobile phone, which contains the identification of the NFC module. To clearly show the identification of the NFC module, other mobile phone structures are omitted in this image. The position of the NFC module in the mobile phone screen can be determined according to the position of the identification in this image. Figure 3 The identification position shown in is only an example and not a limitation on the identification position. In actual production, the identification position can be located at other positions, such as the upper left corner, the middle area of the mobile phone, etc.

[0059] The position of the first wireless communication module in the screen of the current terminal device can be represented by the screen coordinates of the center of the first wireless communication module, and the screen coordinates can include the distances between the center of the first wireless communication module and the edges in two directions of the plane where the screen is located. A plane where a screen is located usually has two perpendicular directions. For example Figure 3 the horizontal direction and the vertical direction in Figure 3 . Each direction has two parallel edges. In each direction, an edge closer to the first wireless communication module can be selected as the reference for calculating the above distances.

[0060] Figure 4 FIG. Figure 4 shows a way to determine the screen coordinates of the center of the first wireless communication module (taking the NFC module as an example). Referring to Figure 4 the example in Figure 4 , the distance x1 between the center of the NFC module and the right edge of the mobile phone screen can be determined from the mobile phone image, and the distance y1 between the center of the NFC module and the upper edge of the mobile phone screen can be determined. After converting x1 and y1 from the image distance (in millimeters) to the pixel distance (in pixels), the screen coordinates of the center of the NFC module can be determined as (x1, y1).

[0061] In the embodiments of the present application, there is no limitation on the orientation of the terminal device Figure 4 The way of placing the mobile phone vertically in Figure 4 is only used as an example and not as a limitation on the embodiments of the present application.

[0062] The conversion from the image distance to the pixel distance can be achieved by calling the following method:

[0063] y = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_MM, x, getResource().getDisplayMetrics()) Expression (1)

[0064] In Expression (1), x represents the data before conversion, and y represents the data after conversion; TypedValue represents a tool class. As a dynamic container, it stores some data values, which are mainly the values in the resource. The TypedValue class can convert the corresponding values into the point values on the actual screen, that is, pixel values; applyDimension is a static method of TypedValue, mainly used to convert other dimension units into pixel units px; COMPLEX_UNIT_MM represents the unit of mm, that is, millimeters; getResource().getDisplayMetrics() represents obtaining the display information of the screen of the current terminal device, such as the screen size, pixel density, font scaling, etc.

[0065] In another alternative implementation, the first position information of the first wireless communication module in the screen of the current terminal device can be obtained in the following manner: query the first position information in a pre-constructed wireless communication module information library. The wireless communication module information library can be pre-constructed in the following manner: obtain a plurality of terminal device images containing the identification information of the wireless communication module; determine the position of the wireless communication module in each terminal device in the screen of the corresponding terminal device according to the position of each identification information in the terminal device image, and store it.

[0066] The plurality of terminal device images can be images of multiple terminal devices of different models. The identification information of the wireless communication module in each terminal device can be identified from the corresponding terminal device images. The images of each terminal device can be obtained through any one of channels such as the official websites of each terminal device, search engines, etc.

[0067] In each terminal device, the position of the wireless communication module in the screen of the corresponding terminal device can be represented by the screen coordinates of the center of the wireless communication module. The screen coordinates can include the distances between the center of the wireless communication module and the two edge directions of the plane where the screen is located. The specific determination method of the screen coordinates can refer to Figure 4 the examples, which will not be elaborated here.

[0068] After determining the positions of the wireless communication modules in the screens of the respective terminal devices, the respective position information can be stored to form a wireless communication module information library. When it is necessary to obtain the position information of the wireless communication module in a certain terminal device in the screen of that terminal device, it can be directly queried in the wireless communication module information library. The pre-constructed wireless communication module information library can improve the acquisition efficiency of the position information of the wireless communication module, and thus improve the screen refreshing efficiency.

[0069] S202, obtain the second position information of the second wireless communication module in the screen of the electronic ink screen to be refreshed.

[0070] In an alternative implementation, an electronic ink screen image containing the identification information of the first wireless communication module can be obtained, and the position of the second wireless communication module in the screen of the electronic ink screen can be determined according to the position of the identification information of the second wireless communication module in the electronic ink screen image, so as to obtain the second position information.

[0071] The identification information of the second wireless communication module in the electronic ink screen can be recognized from the image of the electronic ink screen, and the image of the electronic ink screen can be obtained through any one of channels such as the official website of the electronic ink screen, search engines, etc. The specific method for determining the position of the second wireless communication module on the screen of the electronic ink screen according to the position of the identification information of the second wireless communication module in the image of the electronic ink screen, and then obtaining the second position information, can refer to the method for obtaining the first position information described above.

[0072] The position of the second wireless communication module on the screen of the electronic ink screen to be refreshed can be represented by the screen coordinates of the center of the second wireless communication module. The screen coordinates can include the distances between the center of the second wireless communication module and the edges in two directions of the plane where the screen is located. Similar to the screen of the terminal device, a plane where a screen is located usually has two mutually perpendicular directions, and there are two mutually parallel edges in each direction. In each direction, an edge closer to the first wireless communication module can be selected as the reference for calculating the above distances.

[0073] Figure 5 Shows a method for determining the screen coordinates of the center of the second wireless communication module (taking the NFC module as an example). Referring to Figure 5 the example of, the distance x2 between the center of the NFC module and the left edge of the screen of the electronic ink screen can be determined from the image of the electronic ink screen, and the distance y2 between the center of the NFC module and the lower edge of the screen of the electronic ink screen can be determined. After converting x2 and y2 from the image distance to the pixel distance, the screen coordinates of the center of the NFC module can be determined as (x2, y2). The conversion of the image distance to the pixel distance can be achieved by calling the method shown in expression (1). Figure 5 The indicated identification position of the NFC module is only an example and not

[0074] In the embodiments of the present application, there are no limitations on the placement direction of the electronic ink screen and the identification position of the NFC module. Figure 5 The way of horizontally placing the electronic ink screen and the identification position of the NFC module in are only examples and not limitations on the embodiments of the present application.

[0075] In another alternative embodiment, the second position information can be queried in the wireless communication module information library. Among them, the construction method of the wireless communication module information library can include any one of the following methods: Method 1, obtain multiple electronic ink screen images containing the identification information of the wireless communication module; determine the position of the wireless communication module in each electronic ink screen on the screen of the corresponding electronic ink screen according to the position of each identification information in the corresponding electronic ink screen image, and store it; Method 2, obtain the positions of the wireless communication modules provided by the suppliers of multiple electronic ink screens on the screens of the corresponding electronic ink screens, and store them.

[0076] The multiple electronic ink screen images can be images of multiple electronic ink screens of different models. The identification information of the wireless communication module in each electronic ink screen can be recognized from the corresponding images of each electronic ink screen. The images of each electronic ink screen can be obtained through any one of channels such as the official websites of each electronic ink screen, search engines, etc.

[0077] In each electronic ink screen, the position of the wireless communication module in the screen of the electronic ink screen to which it belongs can be represented by the screen coordinates of the center of the wireless communication module. The screen coordinates can include the distances between the center of the wireless communication module and the two-direction edges of the plane where the screen is located. The specific determination method of the screen coordinates can refer to Figure 5 the examples, which will not be elaborated here.

[0078] After obtaining the positions of the wireless communication modules in the screens of each electronic ink screen, the position information of each can be stored to form a wireless communication module information library. When it is necessary to obtain the position information of the wireless communication module in the screen for a certain electronic ink screen, it can be directly queried in the wireless communication module information library. The pre-constructed wireless communication module information library can improve the acquisition efficiency of the position information of the wireless communication module, and thus improve the screen refreshing efficiency.

[0079] The position information of the wireless communication module in the terminal device and the position information of the wireless communication module in the electronic ink screen can be stored in the same wireless communication module information library, or can be stored in different wireless communication module information libraries.

[0080] S203. Determine the target screen refreshing position according to the first position information and the second position information.

[0081] In an alternative embodiment, the first position information and the second position information can be summed, and the boundary of the target screen refreshing position can be determined according to the sum obtained, and then the target screen refreshing position can be determined.

[0082] In an example, if the first position information is the screen coordinates of the center of the first wireless communication module, such as (x1, y1), and the second position information is the screen coordinates of the center of the second wireless communication module, such as (x2, y2), referring to Figure 6 the target screen refreshing position can be Figure 6The position bounded by the vertical alignment line and the horizontal alignment line in the middle. The distance between the vertical alignment line and the left edge of the mobile phone is x1 + x2, and the distance between the horizontal alignment line and the upper edge of the mobile phone is y1 + y2. An electronic ink screen is placed on the left side of the vertical alignment line and above the horizontal alignment line, so that the center of the NFC module of the electronic ink screen coincides with the center of the NFC module of the mobile phone. After successfully swiping the screen at the target swiping position determined based on the vertical alignment line and the horizontal alignment line, the distance x1 + x2 between the vertical alignment line and the left edge of the mobile phone, the distance y1 + y2 between the horizontal alignment line and the upper edge of the mobile phone, and the model of the mobile phone are jointly stored in the swiping screen database as swiping screen position information for subsequent query.

[0083] S204, output the prompt line corresponding to the target swiping position as the swiping screen prompt information.

[0084] The prompt line corresponding to the target swiping position can be Figure 6 The vertical alignment line and the horizontal alignment line shown to represent the boundary of the target swiping position. Among them, the horizontal alignment line can be the highest alignment line, the lowest alignment line or the middle alignment line. The highest alignment line is the line aligned with the upper edge of the electronic ink screen to be swiped, the lowest alignment line is the line aligned with the lower edge of the electronic ink screen to be swiped, and the middle alignment line can be the line aligned with the middle position in the horizontal direction of the electronic ink screen to be swiped. The prompt line corresponding to the target swiping position can also be a position box. For example, when the alignment lines with the four edges of the electronic ink screen can be displayed simultaneously, the area surrounded by the four alignment lines can completely place the electronic ink screen, and the four alignment lines are the outer frame lines of the electronic ink screen. Another example is that a middle position box line can be displayed with the center of the wireless communication module as the center, and the range surrounded by the middle position box line is smaller than the range surrounded by the outer frame line.

[0085] Refer to Figure 7 In the example of, while outputting the prompt line, text prompts and animation prompts for placing the electronic ink screen can also be output, jointly serving as the swiping screen prompt information.

[0086] Optionally, in step S104, outputting the swiping screen prompt information according to the candidate swiping positions includes: for multiple candidate swiping positions, output the prompt line corresponding to each candidate swiping position in the specified order as the swiping screen prompt information until the swiping screen is successful or all the prompt lines have been output.

[0087] In the case of no historical record information of successful swiping or current swiping failure, the failure rate of random swiping may be relatively low and it affects the user experience. Appropriate positions can be selected from the candidate swiping positions to try to prompt the user to swipe the screen, reducing blind swiping and improving the swiping efficiency.

[0088] In an alternative embodiment, the method for refreshing the electronic ink screen provided by the embodiments of the present application may further include determining the prompt lines corresponding to multiple candidate refreshing positions in the following manner: determining the average value of the sizes of a specified number of wireless communication modules in the first direction; using the average value as the spacing, and determining the prompt lines corresponding to multiple candidate refreshing positions in the first direction of the current terminal device.

[0089] The specified number can be set according to the actual situation. The first direction can be determined according to the installation situation of the wireless communication module in the terminal device. When the wireless communication module is installed in the terminal device, the long side direction of the terminal device can be used as the first direction. For example, a mobile phone is usually rectangular, with a long side and a short side, and the long side direction can be used as the specified direction for determining multiple candidate refreshing positions in the embodiments of the present application. The prompt line corresponding to the candidate refreshing position can be an alignment line in the second direction corresponding to the candidate refreshing position, and the second direction can be a direction perpendicular to the first direction.

[0090] In an example, 10 NFC modules with NFC function and ranked among the top 10 in terms of market occupancy rate in the market can be selected, and the average value of the sizes of these 10 NFC modules in the first direction is calculated. Multiple candidate refreshing positions and their corresponding prompt lines are determined on the screen of the current terminal device, so that the interval between each prompt line is equal to the average value. The prompt lines determined in this way are as Figure 8 shown. Determining the prompt lines of the candidate refreshing positions in this way can minimize the number of prompt lines without missing the refreshing positions, which is beneficial to improving the refreshing efficiency.

[0091] Optionally, the specified order can be the arrangement order of the prompt lines corresponding to multiple candidate refreshing positions in the first direction. Figure 8 Illustrates an example of 4 equally spaced prompt lines. In the Figure 8 example, the arrangement order is from prompt line 1 to prompt line 4. When prompting the user to refresh the screen for the first time, prompt line 1 and the corresponding text prompt and operation key prompt can be output. The output effect is as Figure 9 shown. On the mobile phone screen, prompt line 1 is displayed, and the text prompt "Hold the card horizontally, align the lower edge of the card to the red line, and click to refresh the screen" is displayed below prompt line 1. The operation key prompts "Refresh" and "Reset" are displayed at the bottom of the mobile phone screen. Figure 9 The effect of

[0092] Continue to refer to Figure 8For example, if the user successfully swipes the screen at the swiping position prompted by hint line 1, the output of the hint line can be ended. If the user fails to swipe the screen at the swiping position prompted by hint line 1, the output of hint line 2 can be continued in the order of arrangement. If the user successfully swipes the screen at the swiping position prompted by hint line 2, the output of the hint line can be ended. If the user fails to swipe the screen at the swiping position prompted by hint line 2, the output of hint line 3 can be continued in the order of arrangement. If the user successfully swipes the screen at the swiping position prompted by hint line 3, the output of the hint line can be ended. If the user fails to swipe the screen at the swiping position prompted by hint line 3, the output of hint line 4 can be continued in the order of arrangement. If hint line 4 is the last hint line, the output of the hint line ends regardless of whether the swiping is successful or not.

[0093] In another alternative embodiment, the method for swiping the electronic ink screen provided by the embodiments of the present application may further include determining the hint lines corresponding to multiple candidate swiping positions in the following manner: obtaining the position information of the wireless communication module of each terminal device in the screen of the corresponding terminal device among multiple terminal devices; clustering the obtained position information to obtain a clustering result; and determining the hint lines corresponding to multiple candidate swiping positions on the current terminal device according to the clustering result.

[0094] The multiple terminal devices may be multiple terminal devices with different models. The position information of the wireless communication module in the screen of each terminal device may be the screen coordinates of the center of the wireless communication module in each terminal device. After obtaining the screen coordinates of the center of the wireless communication module in each terminal device, the screen coordinates can be clustered, and the obtained clustering result may be the newly clustered screen coordinates. These new screen coordinates can be respectively used as the center of a candidate swiping position to determine the candidate swiping position. Combining the size of the wireless communication module obtained in advance, a boundary of each candidate swiping position can be further determined, and the alignment line of the boundary can be used as the hint line corresponding to the candidate swiping position.

[0095] In one example, the position of the wireless communication module in each terminal device may be indicated by Figure 10 one of the solid circles shown. The screen coordinates of the center of each solid circle can represent the screen coordinates of the center of the wireless communication module in a terminal device. Through the distribution of the solid circles, the distribution of the wireless communication modules in different terminal devices can be intuitively seen. After clustering the screen coordinates of the centers of the solid circles, a clustering result as shown by the dashed circles in Figure 8 can be obtained. The centers of the multiple clustering results can be respectively used as the center of a candidate swiping position to determine the candidate swiping position. Combining the size of the wireless communication module obtained in advance, the hint lines corresponding to each candidate swiping position can be further determined, as shown in Figure 10 from top to bottom are hint line 1 to hint line 5.

[0096] In the embodiments of the present application, the process of clustering the position information of the wireless communication modules in each terminal device on the screen of the terminal device to which they belong can be implemented by the K-means clustering algorithm or other clustering algorithms.

[0097] By clustering the position information of the wireless communication modules in each terminal device on the screen of the terminal device to which they belong, the swiping position can be predicted more accurately, and a comparison hint line can be provided to prompt the user to swipe the screen, thereby improving the swiping efficiency and the swiping success rate.

[0098] The spacing between the hint lines determined based on the clustering result can be a fixed spacing or an unfixed spacing, that is, the hint lines can be arranged at equal intervals or non-equal intervals, depending on the specific situation of the clustering result. The specified order can be the arrangement order of multiple candidate swiping positions. Figure 10 For example, it can be the order from hint line 1 to hint line 5.

[0099] The screen swiping method for the electronic ink screen provided by the embodiments of the present application may further include: determining the priority of the hint corresponding to each candidate swiping position according to the number of position information included in each type of clustering result. The specified order can be the priority of the hints corresponding to multiple candidate swiping positions.

[0100] Referring to Figure 10 the example in, each dotted circle represents a type of clustering result, each solid circle represents a piece of position information. The more solid circles around each dotted circle and the larger the dotted circle, the more position information is included in the clustering result of this type, and the greater the probability that the position corresponding to the clustering result is the correct swiping position. A higher priority can be set for the hint line corresponding to the clustering result with a larger number of position information, and a lower priority can be set for the hint line corresponding to the clustering result with a smaller number of position information. For the case where the number of position information is the same, the priority can be further set according to the pixel distance between the included position information, so that Figure 10 the priority order of the hint lines in can be, from high to low, hint line 3 (first priority), hint line 4 (second priority), hint line 1 (third priority), hint line 5 (fourth priority), hint line 2 (fifth priority).

[0101] Continuing to refer to Figure 10In an example, when successively outputting each hint line, the hint line 3 with the highest priority can be output first according to the priority order. If the user successfully swipes the screen at the swiping position prompted by the hint line 3, the output of the hint line can be ended. If the user fails to swipe the screen at the swiping position prompted by the hint line 3, the hint line 4 with the second highest priority can be continued to be output; if the user successfully swipes the screen at the swiping position prompted by the hint line 4, the output of the hint line can be ended. If the user fails to swipe the screen at the swiping position prompted by the hint line 4, the hint line 1 with the third highest priority can be continued to be output; if the user successfully swipes the screen at the swiping position prompted by the hint line 1, the output of the hint line can be ended. If the user fails to swipe the screen at the swiping position prompted by the hint line 1, the hint line 5 with the fourth highest priority can be continued to be output; if the user successfully swipes the screen at the swiping position prompted by the hint line 5, the output of the hint line can be ended. If the user fails to swipe the screen at the swiping position prompted by the hint line 5, the hint line 2 with the fifth highest priority can be continued to be output; if the hint line 2 is the last hint line, regardless of whether the screen swiping is successful or not, the output of the hint line can be ended.

[0102] By setting priorities for each hint line, the order in which the user attempts to swipe the screen at each candidate swiping position can be optimized, which helps to more quickly find the correct swiping position and can improve the screen swiping efficiency and success rate.

[0103] In an alternative embodiment, the multiple candidate swiping positions and their corresponding hint lines in the embodiments of the present application can also be randomly set.

[0104] In an example, taking the terminal device as a mobile phone and the wireless communication module as an NFC module as an example, as Figure 11 shown, the method for swiping the screen of the electronic ink screen in the embodiments of the present application may include the following steps S1101 to S1112:

[0107] S1103, determine whether the current screen swiping (the screen swiping for the swiping position in the historical record information of the most recent successful screen swiping) is successful; if so, execute step S1112; if not, execute S1104;

[0108] S1104. Query the first location information of the NFC module in the current mobile phone and the second location information of the NFC module in the electronic ink screen to be refreshed in the wireless communication module information library; if the first location information and the second location information are queried, execute step S1105; if the first location information and / or the second location information is not queried, execute step S1108;

[0109] S1105. Determine the target refresh position according to the first location information and the second location information;

[0112] S1108. Output the hint line corresponding to the first candidate refresh position;

[0113] S1109. Determine whether the current refresh (i.e., the refresh for the current candidate refresh position) is successful; if so, execute step S1112; if not, execute step S1110;

[0114] S1110. Determine whether the current candidate refresh position is the last candidate refresh position; if so, end the refresh; if not, execute step S1111;

[0115] S1111. Output the hint line corresponding to the next candidate refresh position, and then execute step S1109;

[0116] S1112. Record the refresh position of this refresh and end the refresh.
