[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device. At the same time, in the description of the embodiments of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0039] The smart projection phone cases currently on the market combine the ink screen with the phone case. By editing and uploading the background image through the product's supporting APP, the ink screen image can be replaced, allowing users to express their personality.

[0040] The phone case is based on NFC (short-range wireless communication technology) to transmit data and power. It only absorbs a small amount of power from the phone when transmitting pictures. After the transmission is completed, the ink screen does not need to rely on power to maintain the pattern, so there is no need to charge the phone case separately. The working principle of the ink screen is that the ink capsule molecules are pushed to different positions under the control of positive and negative charges, thereby displaying the corresponding pattern. The ink screen can be used for a long time if it is not damaged by external forces.

[0041] According to the background technology of this application, the greater the resolution of the passive ink screen device, the more colors it has, and the higher the operating temperature, the more power and time it takes to refresh the displayed content. However, on the one hand, the passive NFC transmission power that powers the passive ink screen device is limited; on the other hand, the passive ink screen device has limited space and cannot be equipped with a large-capacity battery.

[0042] It is precisely because of the above reasons that the passive ink screen device cannot provide enough power to refresh the screen, resulting in screen refresh failure, such as Figure 1 As shown, since the passive ink screen device is out of power, only part of the image can be displayed at this time.

[0043] Therefore, in order to solve the above problems, the present application proposes a display control method, system, device and computer-readable storage medium for a passive ink screen device to solve the display failure caused by the limited energy storage of the passive ink screen and realize arbitrary screen swiping of the passive ink screen device.

[0044] Specifically, for example, an embodiment of the present application proposes a display control method for a passive ink screen device, and the display control method for the passive ink screen device can be applied to electronic devices, wherein the electronic device may include a device with an NFC module (specifically, an NFC controller). For example, the electronic device may be a mobile phone, a tablet, a notebook, or other device with an NFC module. Correspondingly, if the electronic device is a mobile phone, the passive ink screen device may be a mobile phone case, which is provided with a passive ink screen, so that the user can operate the passive ink screen device to control the application (such as an application installed on the mobile phone) to select the content to be displayed, and send it to the mobile phone case for display, thereby realizing screen swiping of the mobile phone case.

[0045] The display control method of the passive ink screen device is as follows: Figure 2 As shown, the following steps may be specifically included:

[0046] S10, in response to a display control operation on the passive ink screen device, obtaining target content to be displayed, and dividing the target content into at least two sub-contents;

[0047] It should be noted that in this embodiment, the user can operate the electronic device, select the target content to be projected and displayed on the passive ink screen device from the electronic device, and trigger the corresponding display control operation. For example, the user can operate the APP installed on the electronic device, select the corresponding target content, and project it on the ink screen of the passive ink screen device. This embodiment does not specifically limit the type of target content. For example, the target content can be local pictures, texts, or information in the cloud.

[0048] The electronic device can respond to the above-mentioned display control operation on the passive ink screen device to obtain the target content selected by the user.

[0049] Furthermore, the electronic device may divide the target content into at least two sub-contents.

[0050] Specifically, for example, when dividing the target content into multiple sub-contents, the target content can be divided according to the storage capacity of the energy storage capacitor of the passive ink screen device, so that the storage capacity of the passive ink screen device can support the refresh display of each sub-content.

[0051] S20, sending the target sub-content to the passive ink screen device, and controlling the electronic device to charge the passive ink screen device, so that after the passive ink screen device that has finished charging receives the target sub-content, it displays the target sub-content in the corresponding display area through discharge; the target sub-content is the sub-content to be refreshed and displayed in the target content;

[0052] In this embodiment, after the electronic device divides the target content to be displayed into multiple sub-contents, it can send the target sub-content to the passive ink screen device for each sub-content, and in the process of sending the target sub-content to the passive ink screen device, the passive ink screen device can be charged synchronously.

[0053] After receiving the target sub-content, the passive ink screen device can display the target sub-content in the corresponding display area of ​​the passive ink screen device through discharge.

[0054] Specifically, for example, if the target content A is divided into sub-content a1, sub-content a2, and sub-content a3, at this time, sub-content a1 can be first sent to the passive ink screen device as the target sub-content a1, and the energy storage capacitor of the passive ink screen device is charged while sending the target sub-content a1. After receiving the target sub-content a1, the passive ink screen device adjusts from the charging state to the discharging state, and displays the received target sub-content a1 in the corresponding display area by discharging. Then, the electronic device sends the target sub-content a2 to the passive ink screen device, and charges the energy storage capacitor of the passive ink screen device while sending the target sub-content a2. After receiving the target sub-content a2, the passive ink screen device adjusts from the charging state to the discharging state, and displays the received target sub-content a2 in the corresponding display area by discharging, and repeats the cycle until all the target sub-contents are displayed on the passive ink screen device to form the target content.

[0055] S30: Send the new target sub-content to the passive ink screen device until the target content is fully displayed.

[0056] In this embodiment, the electronic device actually displays the target sub-content on the passive ink screen device first, and then sends new target sub-content, and charges the passive ink screen device during the sending process, so that the passive ink screen with sufficient power can normally display the received target sub-content.

[0057] Specifically, for example, Figure 3 As shown, the target content is divided into multiple target sub-contents. The process of sending and displaying all the target sub-contents on the passive ink screen device can be called a refresh display cycle. During this cycle, the number of times the passive ink screen device is charged or discharged is consistent with the number of target sub-contents. That is, each time the passive ink screen device displays a target sub-content, it needs to be charged and discharged once so that the power of the passive ink screen device can normally refresh and display each target sub-content.

[0058] Therefore, this embodiment can respond to the display control operation triggered on the passive ink screen device, obtain the target content selected by the user, and then, the electronic device can divide the target content into at least two target sub-contents. After the electronic device divides the target content to be displayed into multiple target sub-contents, for each target sub-content, the target sub-content can be sent to the passive ink screen device, and in the process of sending the target sub-content to the passive ink screen device, the passive ink screen device is charged synchronously. After receiving the target sub-content, the passive ink screen device can display the target sub-content in the display area corresponding to the passive ink screen device by discharging until all the target sub-contents are displayed on the passive ink screen device. Therefore, compared with the failure of content display caused by insufficient power of the passive ink screen device in the prior art, the present embodiment can pre-divide the content into multiple sub-contents, and synchronously charge the passive ink screen device during the process of sending the sub-content, so that the passive ink screen device has enough power to display the received sub-content, and charge the passive ink screen device again when sending new sub-content, and the passive ink screen device is also discharged again to display the new sub-content, and this cycle is repeated, thereby avoiding the problem of content refresh display caused by the exhaustion of power of the passive ink screen device, ensuring that the passive ink screen device has enough power to refresh and display each sub-content, and realizing the normal refresh display of the passive ink screen device.

[0059] In one embodiment, in the above S20, “sending the target sub-content to the passive ink screen device, and controlling the electronic device to charge the passive ink screen device” may include:

[0060] S201, obtaining position characteristic parameters of the target sub-content relative to the target content;

[0061] S202, determining an area identifier of a display area corresponding to the target sub-content according to the position feature parameter and a preset position mapping relationship between the target sub-content and the display interface of the passive ink screen device;

[0062] S203, charging the energy storage capacitor of the passive ink screen device through the NFC module, and synchronously sending the target sub-content to the passive ink screen device according to the area identifier, so that the passive ink screen device displays the target sub-content in the corresponding display area according to the area identifier.

[0063] In this embodiment, after dividing the target content into a plurality of sub-contents, the electronic device may predetermine position characteristic parameters of the sub-contents relative to the target content, that is, locate the specific positions of the sub-contents in the target content.

[0064] For example, if the target content is an image, the image can be divided into multiple sub-images (i.e., sub-contents in this embodiment). At this time, the position characteristic parameters of the sub-image compared to the image can be position coordinates. For example, if the sub-image is located in the first row and first column, then the position coordinates can be (1, 1).

[0065] Furthermore, the electronic device can determine the area identifier of the display area corresponding to the target sub-content according to the above-mentioned position characteristic parameters and a preset position mapping relationship between the target sub-content and the display interface of the passive ink screen device.

[0066] Among them, the preset position mapping relationship between the sub-content and the display interface of the passive ink screen device can be understood as the existence of a corresponding position when the sub-content is displayed on the passive ink screen device, so that all sub-contents can constitute a complete and correct target content, avoiding problems such as display position errors or position overlaps, which result in the content displayed on the passive ink screen being inconsistent with the content selected by the user to be displayed through the electronic device.

[0067] On this basis, the electronic device can charge the energy storage capacitor of the passive ink screen device through its NFC module, and during the charging process, synchronously send one of the multiple sub-contents as the target sub-content to the passive ink screen device, that is, Figure 3 As shown, the electronic device sends the target sub-content to the passive ink screen device and supplies power to the passive ink screen device in actual synchronization. After receiving the target sub-content, the charged passive ink screen device can display the target sub-content in the display area corresponding to the area identifier by discharging according to the area identifier.

[0068] In this way, in this embodiment, it can ensure that the passive ink screen device has sufficient power to refresh the displayed sub-content, and can also effectively manage the display positions of multiple sub-contents to ensure that the passive ink screen device can normally display the complete projection content.

[0069] In one embodiment, in the above S10, “dividing the target content into at least two sub-contents” may include:

[0070] S101, detecting the storage capacity of the energy storage capacitor of the passive ink screen;

[0071] S102, determining at least two sub-contents according to the energy storage space and the file size of the target content, wherein the power consumed by the passive ink screen device to refresh and display each of the sub-contents is less than or equal to the storage capacity of the energy storage space.

[0072] In this embodiment, in order to ensure that the power of the passive ink screen device after each charge can support the refresh display of the corresponding sub-content, the electronic device can pre-detect the energy storage space of the energy storage capacitor of the passive ink screen device when dividing the target content.

[0073] Furthermore, at least two sub-contents are determined according to the storage space and the file size of the target content.

[0074] Specifically, for example, the electronic device can calculate the standard file size of the content that can be refreshed by the amount of electricity stored in the energy storage space of the energy storage capacitor, use the standard file size as a reference, and divide the target content so that the file sizes of the obtained sub-contents are less than or equal to the above standard file size. In this way, the amount of electricity consumed by the passive ink screen device to refresh the display of each sub-content is less than or equal to the storage amount of the energy storage space.

[0075] Therefore, in this embodiment, when dividing the display content, the electronic device fully considers the energy storage space of the energy storage capacitor of the passive ink screen device, ensuring that the power of the passive ink screen device after each charge can at least refresh and display the currently received sub-content, ensuring the normal display of the sub-content. In this way, the entire target content can be refreshed and displayed normally, avoiding the situation where the power of the passive ink screen device is still unable to support the refresh display of the sub-content even after the content is segmented.

[0076] In one embodiment, before the above S20, “sending the target sub-content to the passive ink screen device”, the following steps are included:

[0077] S40, determining a refresh display period according to the file size corresponding to each sub-content;

[0078] In this embodiment, after dividing the target content into a plurality of sub-contents, the electronic device may calculate the file size of each sub-content and determine the refresh display cycle according to the file size.

[0079] Among them, the refresh display cycle includes the content identifier corresponding to each sub-content and the corresponding transmission time information when the electronic device sends each sub-content to the passive ink screen device, wherein the transmission time information includes the time consumed by the electronic device to send each sub-content to the passive ink screen device, and the time can be calculated based on the transmission rate and file size.

[0080] It should be noted that, in this embodiment, Figure 3 As shown, the complete display cycle of the target content includes the refresh display cycle of each sub-content (during this refresh display cycle, the passive ink screen device charges and receives the sub-content, and discharges to display the sub-content). The electronic device can send and display all sub-content corresponding to the target content on the passive ink screen device.

[0081] On this basis, in the above S20, “sending the target sub-content to the passive ink screen device” may include:

[0082] S201, acquiring a refresh display period of the target sub-content according to the content identifier of the target sub-content;

[0083] S202: Send the target sub-content to the passive ink screen device according to the refresh display cycle.

[0084] In this embodiment, before transmitting the current target sub-content to the passive ink screen device, the electronic device can obtain the content identifier of the current target sub-content, wherein the content identifier can be the position coordinates of the target sub-content compared to the target content, such as the row and column coordinates of the target sub-content described in the above embodiment. Furthermore, according to the content identifier of the target sub-content, the refresh display cycle can be queried to obtain the transmission order of the target sub-content.

[0085] The transmission sequence may include a transmission start time node of each target sub-content, where the node is used to indicate that the target sub-content is to be transmitted from the time node, and the target sub-content is sent to the passive ink screen device.

[0086] Furthermore, the electronic device can send the current target sub-content to the passive ink screen device according to the transmission time information.

[0087] Specifically, for example, the electronic device may query the refresh display cycle to obtain the transmission start time node of the current target sub-content, and then may send the target sub-content to the passive ink screen display device according to the transmission start time node.

[0088] Among them, it is worth noting that Figure 4As shown, multiple target sub-contents can also be sent to the passive ink screen device in sequence, and can also be sent in odd-even order of the target sub-contents, such as sending the odd-numbered target sub-contents first, and then sending the even-numbered target sub-contents. In addition, the target sub-contents can also be sent to the passive ink screen device in a preset sending order, wherein the preset sending order can be pre-specified by the user or determined by the electronic device. It can be understood that in the refresh display cycle, since there are content identifiers of each target sub-content, the transmission order of each target sub-content has been specified in the refresh display cycle. When the electronic device queries the refresh display cycle according to the content identifier of the target sub-content, it can determine the transmission start time node of each target sub-content, and send the corresponding target sub-content to the passive ink screen device according to the transmission start time node.

[0089] Furthermore, in the above S40, “determining a refresh display period according to the file size corresponding to each target sub-content” may include:

[0090] S401, for each sub-content, calculating the transmission time consumed for sending the sub-content to the passive ink screen device according to the file size and transmission rate corresponding to the sub-content;

[0091] S402, extracting edge feature parameters of the target content, and identifying key feature information in the target content according to the edge feature parameters, wherein the key feature information includes subject feature information and background feature information;

[0092] S403, determining the transmission order of the sub-content where the key feature information is located according to the key feature information and the mapping relationship between the key feature information and the transmission order;

[0093] S404: Determine the refresh display period according to the transmission duration and transmission sequence corresponding to each of the sub-contents.

[0094] In this embodiment, the electronic device can calculate, for each sub-content, the transmission time required to transmit the sub-content to the passive ink screen device according to the file size of the sub-content and the current transmission rate.

[0095] Furthermore, the electronic device may also extract edge feature parameters of the target content, and identify key feature information such as subject feature information and background feature information in the target content according to the edge feature parameters.

[0096] It can be understood that in this embodiment, according to the above description, when the electronic device sends multiple sub-contents to the passive ink screen device, the sub-contents can be sent to the passive ink screen device in a preset sending order, wherein the preset sending order can be pre-specified by the user or determined by the electronic device. In this embodiment, the transmission start time node of the target sub-content to which each key feature information belongs can be determined based on the key feature information in the target content.

[0097] Specifically, for example, the electronic device may determine the transmission order of the sub-content where the key feature information is located according to the key feature information and the mapping relationship between the key feature information and the transmission order. The transmission order may specifically be a transmission start time node.

[0098] For example, based on the mapping relationship between the above-mentioned key feature information and the transmission start time node, the transmission start time of the sub-content to which the main feature information belongs can be determined as an earlier transmission start time node, and the start time of the sub-content to which the background feature information belongs can be determined as a later transmission start time node. At this time, the above-mentioned mapping relationship is used to give priority to displaying the sub-content containing the main body.

[0099] On this basis, the electronic device can determine the refresh display period according to the transmission duration and the transmission start time node corresponding to each sub-content.

[0100] In this way, this embodiment can ensure that the passive ink screen device can preferentially display the main part of the target image, realize a more flexible refresh display mode of the passive ink screen, and thus improve the display effect of the passive ink screen.

[0101] In one embodiment, the present application also proposes a display control method for a passive ink screen device, which can be applied to a passive ink screen device, which can be a mobile phone case or a device with a passive ink screen that performs NFC communication with an electronic device. The display control method of the passive ink screen device is as follows: Figure 5 As shown, the following steps may be included:

[0102] S50, controlling the passive ink screen device to be charged via an electronic device, and synchronously receiving target sub-content; wherein the target sub-content is obtained by dividing the target content by the electronic device;

[0103] S60, after receiving the target sub-content, controlling the passive ink screen device that has finished charging to discharge, so as to display the target sub-content in a corresponding display area;

[0104] S70, until the passive ink screen device is controlled to display the target content.

[0105] In this embodiment, the electronic device can respond to the display control operation of the passive ink screen device, obtain the target content selected by the user, and then divide the target content according to the storage capacity of the energy storage capacitor of the passive ink screen device, so that the storage capacity of the passive ink screen device can support the refresh display of each target sub-content. After the electronic device divides the target content to be displayed into multiple target sub-contents, for each target sub-content, the target sub-content can be sent to the passive ink screen device, and in the process of sending the target sub-content to the passive ink screen device, the passive ink screen device can be charged synchronously.

[0106] After receiving the target sub-content, the charged passive ink screen device can control the discharge of the energy storage capacitor of the passive ink screen device to display the target sub-content in the corresponding display area of ​​the passive ink screen device.

[0107] For example, if the target content A is divided into target sub-content a1, target sub-content a2, and target sub-content a3, at this time, the target sub-content a1 can be sent to the passive ink screen device first, and while sending the target sub-content a1, the energy storage capacitor of the passive ink screen device is charged. After receiving the target sub-content a1, the passive ink screen device adjusts from the charging state to the discharging state, and displays the received target sub-content a1 in the corresponding display area by discharging. Then, the electronic device sends the target sub-content a2 to the passive ink screen device, and while sending the target sub-content a2, the energy storage capacitor of the passive ink screen device is charged. After receiving the target sub-content a2, the passive ink screen device adjusts from the charging state to the discharging state, and displays the received target sub-content a2 in the corresponding display area by discharging, and repeats the cycle until all the target sub-contents are displayed on the passive ink screen device to form the target content.

[0108] Furthermore, in the above S60, “discharging the passive ink screen device after charging is controlled to display the target sub-content in the corresponding display area” may include:

[0109] S601, receiving an area identifier sent by the electronic device, where the area identifier is determined by the passive ink screen device according to a position feature parameter of the target sub-content relative to the target content, and a preset position mapping relationship between the target sub-content and a display interface of the passive ink screen device;

[0110] S602: Determine, according to the area identifier, a display area of ​​the passive ink screen device corresponding to the target sub-content;

[0111] S603, controlling the passive ink screen device that has finished charging to discharge, so as to display the target sub-content in the display area.

[0112] It should be noted that, in this embodiment, after dividing the target content into multiple target sub-contents, the electronic device can pre-determine the position characteristic parameters of the target sub-content relative to the target content, that is, locate the specific position of the target sub-content in the target content.
