[0035] It should be noted that the display method, device and program product of the e-ink screen device provided in this application can be used in the field of electronic display technology, or in any field other than the field of electronic display technology. The application field of the display method, device and program product of the e-ink screen device in this application is not limited.

[0036] It should be noted that in the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned. These should be regarded as exemplary and are only intended to illustrate the feasibility of implementing the technical solution of this application. However, they do not mean that the applicant has used or necessarily used the solution.

[0037] E-ink displays have been widely used in education, office work, and reading due to their low power consumption, paper-like display effect, and eye-friendly characteristics.

[0038] Currently, e-ink devices adopt a single-screen structure design, which displays only one page of content at a time. Users need to flip through pages to view related content. However, in the above method, single-screen display cannot present multiple related contents at the same time. Users need to switch frequently in scenarios such as reading for comparison, which makes the operation cumbersome and reading efficiency low.

[0039] To address the aforementioned problems, this application provides a display method for an e-ink screen device. The e-ink screen device includes a first e-ink screen and a second e-ink screen, and a control component for controlling the display on both the first and second e-ink screens. When a first book is launched on the first e-ink screen, first content to be displayed on the first e-ink screen is obtained from the first book. Based on the first content, second content is determined from the first book, where the second content is the content on the previous or next page of the first content. The first content and a first control for switching display modes are displayed on the first e-ink screen, where the display modes include single-screen display and dual-screen display. In response to touch of the first control, the second content is displayed on the second e-ink screen.

[0040] In the above method, by configuring a dual-screen structure for the e-ink device and having the display controlled collaboratively by a control component, when the first book is started and the first content is displayed, the second content on the previous or next page is simultaneously determined. A first control for switching display modes is also added. In response to the touch of the first control, the second content can be displayed on the second e-ink screen. This not only enables flexible switching between single-screen and dual-screen display, but also allows the related content to be displayed synchronously, solving the problem of frequent switching of comparison content on a single screen. This simplifies user operation and improves the efficiency of comparison reading and continuous reading scenarios.

[0041] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0042] Figure 1 This is a schematic flowchart illustrating a display method for an e-ink screen device provided in an embodiment of this application. Please refer to... Figure 1 As shown, the method may include the following steps:

[0043] S101. When starting the first book in the first e-ink screen, retrieve the first content in the first book that is to be displayed on the first e-ink screen.

[0044] The execution subject of this application embodiment can be an e-ink screen device, or a display device of the e-ink screen device disposed in the e-ink screen device. The display device of the e-ink screen device can be implemented by software, or by a combination of software and hardware.

[0045] In some implementations, the e-ink display device includes a first e-ink display and a second e-ink display, and the e-ink display device includes a control component for controlling the display of the first e-ink display and the second e-ink display.

[0046] In one possible implementation, the e-ink device may include two independently controlled e-ink screens, namely a first e-ink screen and a second e-ink screen.

[0047] In one possible implementation, the first book is the target reading document selected and launched by the user on the first e-ink screen. The format of the first book includes multiple formats such as e-book and document.

[0048] In one possible implementation, the first content is the content of the first book to be displayed on the first e-ink screen, which can be specific to a certain page or a certain paragraph of a chapter of the first book.

[0049] In one possible implementation, when a user opens the first book on the first e-ink screen for the first time, the first content is the first page of the first book; if the user is not opening it for the first time, the first content is the last content the user was reading when they last used the e-ink screen device to read the first book.

[0050] In one possible implementation, before launching the first book on the first e-ink screen, the first e-ink screen can display the main interface of the e-ink device, including application entry points such as bookshelf, textbooks, video teaching, and learning progress. The second e-ink screen can display the secondary interface of the e-ink device, including application entry points such as homework, test papers, notes, and calligraphy and painting. The control component can monitor the user's touch operation on the first e-ink screen in real time.

[0051] S102. Based on the first content, determine the second content in the first book, wherein the second content is the content on the previous or next page of the first content.

[0052] In one possible implementation, both the second content and the first content can be content from the first book. When the first e-ink screen is the left screen, the second content can be the content on the next page of the first content; when the first e-ink screen is the right screen, the second content can be the content on the previous page of the first content.

[0053] For example, when the first e-ink screen is the left screen, the first content is the content of page 1 of the first book, and the second content is the content of page 2 of the first book.

[0054] S103. Display first content and a first control for switching display modes on a first e-ink screen, the display modes including single-screen display and dual-screen display.

[0055] In one possible implementation, the first control is an interactive button that is displayed synchronously with the first content on the first e-ink screen. The display style of the first control can be an icon, a text button, etc. After the user touches the first control, the control component can be triggered to execute the dual-screen display logic.

[0056] In one possible implementation, the display mode is the content display method of the e-ink screen device, including single-screen display and dual-screen display modes, which can be switched by the user through touch operation of the first control, so as to adapt to the needs of different reading scenarios.

[0057] S104. In response to a touch of the first control, display the second content on the second e-ink screen.

[0058] In one possible implementation, when the display mode is single-screen display, in response to touch of the first control, the display mode can be switched to dual-screen display, and the second content can be displayed on the second e-ink screen.

[0059] For example, when the first page of the first book is displayed on the first e-ink screen and the content of the first book is not displayed on the second e-ink screen, if the user touches the first control, the first page of the first book will be displayed on the first e-ink screen and the second page of the first book will be displayed on the second e-ink screen.

[0060] In some implementations, after the second content is displayed on the second e-ink screen, in response to a further touch of the first control, the display of the second content on the second e-ink screen is canceled, and the display mode is switched to single-screen display.

[0061] For example, when the first page of a first book is displayed on the first e-ink screen and the second page of the first book is displayed on the second e-ink screen, if the user touches the first control, the first page of the first book will be displayed on the first e-ink screen and the second page of the first book will be de-displayed on the second e-ink screen.

[0062] In this way, by touching the first control again in the dual-screen display state, the second content display on the second e-ink screen can be canceled and the display can be returned to single-screen mode. This allows for flexible shutdown of the second e-ink screen display when no auxiliary content is needed, enabling convenient switching between the two display modes. This meets the needs of users in diverse reading scenarios (parallel reading / single-screen focused reading), simplifies the operation logic, avoids the cumbersome process of setting up an additional switching entry, and thus improves the user experience.

[0063] Next, combined Figure 2 ,right Figure 1 The display method of the e-ink screen device shown will be further explained, for example, taking the first e-ink screen as the left screen. Figure 2 This is a schematic diagram illustrating a display method for an e-ink screen device provided in an embodiment of this application. Figure 2 As shown, the e-ink device includes a first e-ink screen and a second e-ink screen. The first e-ink screen includes a first book. When the first book is started on the first e-ink screen, first content and a first control can be displayed on the first e-ink screen. In response to the touch of the first control, second content can be displayed on the second e-ink screen.

[0064] In some implementations, after the second content is displayed on the second e-ink screen, a launch operation for an application tool in the e-ink screen device can be received, and the application tool can be displayed on the second e-ink screen.

[0065] In one possible implementation, the application tools could include: a draft paper tool, a calculator, and a notebook, etc.

[0066] In some implementations, displaying application tools on a second e-ink screen may include:

[0067] When the application tool is the scratch paper tool, the scratch paper tool is displayed on the second e-ink screen; when the application tool is the calculator, the second content is canceled from being displayed on the second e-ink screen and the calculator is displayed; when the application tool is the notebook, the second content is canceled from being displayed on the second e-ink screen and the notebook content corresponding to the first content is displayed.

[0068] In one possible implementation, when the application tool is a draft paper tool, the draft paper can be displayed on top of the second content displayed on the second ink screen. The draft paper can occupy half of the second ink screen. For example, the first ink screen displays page 10 of the first book (e.g., a math book), and the second ink screen displays page 11 of the math book. When the user clicks on the draft paper, the draft paper can be suspended in the lower half of the second ink screen by default, that is, it will cover the lower half of the content of page 11 on the second ink screen, but will not cover the upper half of the content.

[0069] The draft paper can include multiple pages, allowing users to perform calculations on each page. For example, after completing calculations on page 1, clicking on page 2 will display a new blank draft paper, allowing users to continue their calculations. Furthermore, the calculations on page 1 will be retained, and users can read the previously completed calculations on page 1 when they click on page 1 again.

[0070] The draft paper may also include a fourth control for moving the draft paper vertically. In response to touch on the fourth control, the draft paper can jump between vertical positions. For example, if the draft paper is displayed on the lower half of the second e-ink screen (i.e., obscuring the content of the lower half of the screen but not the content of the upper half), when the user touches the fourth control, the draft paper can jump to the upper half of the second e-ink screen (i.e., obscuring the content of the upper half of the screen but not the content of the lower half).

[0071] The draft paper may also include a fifth control, which is used to switch the e-ink screen on which the draft paper is located. In response to touch of the fifth control, the draft paper can switch to the e-ink screen on which it is located. For example, if the draft paper is displayed on the lower half of the second e-ink screen, when the user touches the fifth control, the draft paper can switch to the lower half of the first e-ink screen.

[0072] For example, when the first page of a first book is displayed on the first e-ink screen and the second page of the first book is displayed on the second e-ink screen, if the user selects to open the calculator, then the first page of the first book will be displayed on the first e-ink screen and the calculator will be displayed on the second e-ink screen.

[0073] In this way, by displaying a second content on the second e-ink screen, users can flexibly switch between displaying applications such as scratch paper, calculator, and notebook. Different display logic is designed for different applications (e.g., the scratch paper tool supports overlay display, and the calculator and notebook tools replace the original second content display). This not only expands the functional boundaries of dual-screen e-ink devices, but also allows users to access applications other than the reader without switching applications or devices during reading, meeting the multitasking needs in learning, office and other scenarios, and improving reading and collaboration efficiency.

[0074] It should be noted that the display mode of the e-ink device can be preset or determined based on the user's historical reading habits. For example, if the user is accustomed to reading content on the first e-ink screen and not using the second e-ink screen, then when the first book is launched on the first e-ink screen, the first content can be displayed only on the first e-ink screen.

[0075] Next, combined Figure 3 This document explains how to launch the application tool on an e-ink display device. For example, it uses a draft paper tool as the application tool and the first e-ink display as the left screen. Figure 3 This is a schematic diagram of an application startup tool for an e-ink screen device provided in an embodiment of this application. It should be noted that... Figure 3 Taking the draft paper tool as an example, such as Figure 3 As shown, a draft paper can be displayed above the second content displayed on the second e-ink screen. The draft paper occupies half of the second e-ink screen and floats on the lower half of the second e-ink screen, obscuring the lower half of the second content. The draft paper includes a fourth control and a fifth control.

[0076] In response to a touch of the fourth control, the draft paper floats above the second ink screen, obscuring the upper half of the second content and displaying the lower half of the second content;

[0077] In response to a touch on the fifth control, the draft paper floats above the upper half of the first ink screen, obscuring the upper half of the first content and displaying the lower half of the first content.

[0078] In this embodiment, the e-ink screen device includes a first e-ink screen and a second e-ink screen. The e-ink screen device includes a control component for controlling the display of the first e-ink screen and the second e-ink screen. When a first book is launched in the first e-ink screen, the device acquires first content from the first book that is to be displayed on the first e-ink screen. Based on the first content, the device determines second content in the first book, where the second content is the content of the previous or next page of the first content. The device displays the first content and a first control for switching display modes on the first e-ink screen, where the display modes include single-screen display and dual-screen display. In response to touch of the first control, the device displays the second content on the second e-ink screen.

[0079] In the above method, by configuring a dual-screen structure for the e-ink device and having the display controlled collaboratively by a control component, when the first book is started and the first content is displayed, the second content on the previous or next page is simultaneously determined. A first control for switching display modes is also added. In response to the touch of the first control, the second content can be displayed on the second e-ink screen. This not only enables flexible switching between single-screen and dual-screen display, but also allows the related content to be displayed synchronously, solving the problem of frequent switching of comparison content on a single screen. This simplifies user operation and improves the efficiency of comparison reading and continuous reading scenarios.

[0080] Based on the above embodiments, after displaying the second content on the second e-ink screen, it is also possible to:

[0081] Based on historical reading speed, determine the first cached content corresponding to the first e-ink screen and the second cached content corresponding to the second e-ink screen; cache the first cached content in the cache corresponding to the first e-ink screen, and cache the second cached content in the cache corresponding to the second e-ink screen.

[0082] In one possible implementation, historical reading speed is the average time it takes for a user to read a single page of content.

[0083] In one possible implementation, historical reading speed can be determined as follows: Real-time detection and storage of the user's dwell time while reading each page on the first and second e-ink screens, followed by averaging the recorded times to obtain the historical reading speed. Alternatively, historical reading speed can be determined by comprehensively considering the user's long-established reading habits. For example, based on the user's preferred reading time periods, focus on different topics, and whether they prefer detailed reading or rapid skimming, a time interval suitable for the user's reading style is first defined. Then, combined with the user's regular reading pace within that interval, a historical reading speed consistent with the user's habits is determined.

[0084] In one possible implementation, the first cached content is a set of content that the user is about to read on the first e-ink screen, determined based on the user's historical reading speed. After caching, the content can be loaded quickly.

[0085] In one possible implementation, based on the user's historical reading speed, the set of content that the user is about to read on the second e-ink screen is determined and associated with the page numbers of the first cached content. After caching, the content of the two screens is refreshed synchronously and quickly.

[0086] In one possible implementation, the cache corresponding to the first e-ink screen refers to a local storage area that is separately allocated for the first e-ink screen in the e-ink device. It is used to store the first cache content and has the characteristics of fast read speed and small space occupation, which is suitable for the low power consumption operation requirements of e-ink screen.

[0087] In one possible implementation, the cache corresponding to the second e-ink screen refers to a local storage area in the e-ink device that is separately allocated for the second e-ink screen, used to store the second cache content, and works in conjunction with the cache of the first e-ink screen to ensure the content loading efficiency when the two screens are turned synchronously.

[0088] In one possible implementation, if the historical reading speed is greater than or equal to the first speed, indicating that the user is reading the content quickly, then the first cached content and the second cached content can be determined to be more (the number of the first cached content and the second cached content can be preset, and this application embodiment does not limit this). If the historical reading speed is less than the first speed, indicating that the user is reading the content slowly, then the first cached content and the second cached content can be determined to be less (the number of the first cached content and the second cached content can be preset, and this application embodiment does not limit this). The first speed can be preset, for example, to 1.5 pages per minute.

[0089] For example, when the first e-ink screen displays page 3 of the first book and the second e-ink screen displays page 4 of the first book, and the historical reading speed is less than the first speed, the first cached content and the second cached content may respectively include: page 1, page 2, page 3, page 4, page 5, and page 6 of the first book.

[0090] For example, if the first e-ink screen displays page 3 of the first book and the second e-ink screen displays page 4 of the first book, and the historical reading speed is greater than the first speed, then the first cached content and the second cached content may respectively include pages 1 to 15 of the first book.

[0091] In one possible implementation, when caching the first and second cached contents, icons, annotations, and images in the first and second cached contents can be cached first, followed by text content. In this way, by prioritizing the caching of non-text elements that are more visually noticeable and crucial to understanding the content during the reading process, users can quickly read auxiliary information such as charts, annotations, and icons after switching the content displayed on the e-ink screen, avoiding interruptions to the reading rhythm due to waiting for text to load. At the same time, it adapts to the partial refresh characteristics of e-ink screens, reduces the frequency of full-screen refreshes, lowers device power consumption, and further improves the smoothness and comfort of dual-screen reading.

[0092] It should be noted that, for comparative reading scenarios, when displaying the first content of the first book on the first e-ink screen and the translation or annotation on the second e-ink screen, the first content, the content before the first content, and the content after the second content can be cached in the cache area corresponding to the first e-ink screen (the amount of cached content can be determined based on the historical reading speed), and the corresponding translation or annotation can be cached in the cache area corresponding to the second e-ink screen. This can improve loading efficiency, and the cache areas of the first and second e-ink screens are isolated from each other, making it less likely to conflict.

[0093] In one possible implementation, the user can choose to prioritize caching a specific chapter or content from the first book. Furthermore, when the cached storage space corresponding to a particular e-ink screen is greater than or equal to a preset space threshold, the content in the cache corresponding to that e-ink screen can be cleared. For example, content from pages farther away from the current content can be cleared first, or content from pages with lower access frequency can be cleared first. The preset space threshold is, for example, 50 megabytes (MB).

[0094] In this embodiment, the historical reading speed is determined by combining the user's average reading time per page with their reading habits. Based on this speed, the amount of cached content on the first and second e-ink screens is dynamically matched. At the same time, independent cache areas are allocated to the two screens to store continuously related cached content. This not only adapts the caching strategy according to the user's reading rhythm (expanding the cache range during high-speed reading and simplifying the cached content during low-speed reading), but also enables fast loading of content on both screens by combining independent caching, avoiding page turning lag. Furthermore, it reduces the device's storage resource consumption and power consumption while ensuring smooth reading, significantly improving the personalized reading experience of dual-screen e-ink devices.

[0095] Based on the above embodiments, when the first e-ink screen is the left screen, the first e-ink screen includes a second control for scrolling down and a third control for scrolling up. After the second content is displayed on the second e-ink screen, the content can be scrolled down using the second control and scrolled up using the third control. Next, in conjunction with... Figure 4 The method for turning pages is explained. For example,Figure 4 This is a flowchart illustrating a page-turning method provided in an embodiment of this application, as shown below. Figure 4 As shown, the method includes:

[0096] S401. In response to a touch of the second control, display third content on the first e-ink screen and display fourth content on the second e-ink screen, wherein the third content is the next page of the second content and the fourth content is the next page of the third content.

[0097] In one possible implementation, the second control can be set on either the first or second ink screen.

[0098] In one possible implementation, in response to a touch of the second control, third content can be read from the cache corresponding to the first e-ink screen and displayed on the first e-ink screen, and fourth content can also be read from the cache corresponding to the second e-ink screen and displayed on the second e-ink screen.

[0099] For example, if page 3 of a first book is displayed on the first e-ink screen and page 4 of the first book is displayed on the second e-ink screen, in response to touch of the second control, page 5 of the first book can be displayed on the first e-ink screen and page 6 of the first book can be displayed on the second e-ink screen.

[0100] In one possible implementation, in response to a touch of the second control, the third content can be displayed on the first e-ink screen first, and then the fourth content can be displayed on the second e-ink screen.

[0101] For example, if page 3 of a first book is displayed on the first e-ink screen and page 4 of the first book is displayed on the second e-ink screen, in response to touch of the second control, page 3 of the first book displayed on the first e-ink screen can be switched to page 5 first, and then page 4 of the first book displayed on the second e-ink screen can be switched to page 6.

[0102] S402. In response to a touch of the third control, display the fifth content on the first e-ink screen and the sixth content on the second e-ink screen, wherein the fifth content is the previous page of the sixth content and the sixth content is the previous page of the third content.

[0103] In one possible implementation, the third control can be set on either the first or second ink screen.

[0104] In one possible implementation, in response to a touch of the third control, the fifth content can be read from the cache corresponding to the first e-ink screen and displayed on the first e-ink screen, and the sixth content can also be read from the cache corresponding to the second e-ink screen and displayed on the second e-ink screen.

[0105] For example, if page 5 of a first book is displayed on the first e-ink screen and page 6 of the first book is displayed on the second e-ink screen, in response to touch of a third control, page 3 of the first book can be displayed on the first e-ink screen and page 4 of the first book can be displayed on the second e-ink screen.

[0106] In one possible implementation, in response to a touch of a third control, the fifth content can be displayed first on the first e-ink screen, and then the sixth content can be displayed on the second e-ink screen.

[0107] For example, if page 5 of a first book is displayed on the first e-ink screen and page 6 of the first book is displayed on the second e-ink screen, in response to touch of the third control, page 5 of the first book displayed on the first e-ink screen can be switched to page 3 first, and then page 6 of the first book displayed on the second e-ink screen can be switched to page 4.

[0108] Based on the above embodiments, when the content of the first book is displayed on the first e-ink screen and the annotations or translations of the content are displayed on the second e-ink screen, the content displayed on the first e-ink screen can be turned page by page in response to the touch of the second control or the third control, and the annotations or translations of the content displayed on the second e-ink screen can also be turned page by page.

[0109] In this embodiment, by responding to touch on the second and third controls, content is preferentially read from the independent caches of the two screens to achieve synchronous or step-by-step page turning on both screens. It also adapts to the linked page turning logic of the main text and annotations / translations. This can improve the page turning response speed by combining cached content reading, reduce the refresh delay of the e-ink screen, and improve the reading smoothness and operation convenience of the dual-screen e-ink screen device.

[0110] Next, combined Figure 5 This section explains the method for page turning when the first and second e-ink screens display content simultaneously, using the first e-ink screen as the left screen as an example. Figure 5 This application provides a schematic diagram of a page-turning mechanism, as shown in the embodiment of the present application. Figure 5 As shown, the first e-ink screen includes a second control and a third control. The first e-ink screen displays page 1 of the first book, and the second e-ink screen displays page 2 of the first book. In response to touch of the second control, the page can be turned down, and the first e-ink screen displays page 3 of the first book, and the second e-ink screen displays page 4 of the first book. In response to touch of the third control, the page can be turned up, and the first e-ink screen displays page 1 of the first book, and the second e-ink screen displays page 2 of the first book.

[0111] It should be noted that, in addition to Figure 4 The page-turning method shown can also be used to turn pages of the content displayed on the first and second e-ink screens in the following ways:

[0112] Obtain the user's historical reading speed; based on the first content, the second content, and the historical reading speed, predict the first time required to read the first content and the second content; based on the first time, turn pages on the first e-ink screen and the second e-ink screen.

[0113] In one possible implementation, the method for obtaining the user's historical reading speed is the same as described in the above embodiments, and will not be repeated here.

[0114] In one possible implementation, a first book can be determined based on the first content and the second content. Then, based on the user's historical reading speed of the first book, the first time required for the user to read the first content and the second content can be predicted. Based on the first time, the first e-ink screen and the second e-ink screen can be turned.

[0115] In one possible implementation, when the first book is a teaching material, a first duration can be determined based on the first content, the second content, and the user's level of mastery of the first book. Based on the first duration, the first and second e-ink screens can be turned. Specific implementation methods include: determining the first book, the chapters of the first content, and the chapters of the second content based on the first and second content; determining the user's grades based on the first book; and determining the user's level of mastery of the first book based on the user's grades, the accuracy rate of assignments in the chapters of the first content, and the accuracy rate of assignments in the chapters of the second content, and determining the first duration. Based on the first duration, the first and second e-ink screens can be turned.

[0116] In one possible implementation, when the first book is a teaching material, a first duration can be determined based on the first content, the second content, and the user-selected mode. Based on the first duration, the first and second e-ink screens can be turned. The specific implementation includes: determining the first book based on the first and second content, and then determining the first duration based on the first book and the user-selected mode. Based on the first duration, the first and second e-ink screens can be turned.

[0117] For example, if the first book is a math book and the user selects the preview mode, the first duration can be longer; if the first book is a math book and the user selects the review mode, the first duration can be shorter.

[0118] In the above embodiments, a pop-up window can be displayed to show a prompt message before the first and second e-ink screens are turned over. The prompt message is used to remind the user that the first and second e-ink screens are about to turn over. The preset duration is, for example, 5 seconds.

[0119] In one possible implementation, within a preset duration, the window also includes a sixth control. The sixth control is used to cancel the page turning of the first and second ink screens. In response to a touch of the sixth control, the page turning of the first and second ink screens during the first duration is canceled, so as to continue reading the content currently displayed on the first and second ink screens.

[0120] In one possible implementation, if the user does not touch the sixth control, the first and second e-ink screens will be flipped during the first duration.

[0121] In this embodiment, the first reading time is predicted based on historical reading speed, book type, knowledge mastery level, and user-selected mode. Then, intelligent page turning is achieved by combining a preset page-turning prompt window and a sixth control for canceling page turning. This can dynamically adapt the dual-screen page turning rhythm according to the user's personalized reading habits and learning needs (such as extending the textbook preview time and shortening the review time). At the same time, the page turning warning and manual cancellation functions can ensure the user's reading autonomy, avoid accidental page turning that interrupts reading or learning, and eliminate the tedious operation of manual page turning, thereby improving the efficiency and user experience of e-ink screen devices in reading and learning scenarios.

[0122] Next, combined Figure 6 This section describes another method for page turning when the first and second e-ink screens display content simultaneously, using the first e-ink screen as the left screen and a preset duration of 5 seconds as an example. Figure 6 Another schematic diagram of page turning provided in this application embodiment, such as Figure 6 As shown, the first e-ink screen displays page 1 of the first book, and the second e-ink screen displays page 2 of the first book. When the first duration is determined, a pop-up window appears after a preset time before the first duration expires. The window includes a prompt message and a sixth control. The prompt message reads, "Pagination will turn in five seconds. To cancel this page turn, please click the 'Cancel' button." At this time, the first e-ink screen still displays page 1 of the first book, and the second e-ink screen still displays page 2 of the first book. If the e-ink screen device does not receive a touch on the sixth control within the preset time, the page will turn after the preset time, with the first e-ink screen displaying page 3 of the first book and the second e-ink screen displaying page 4 of the first book.

[0123] Based on the above embodiments, after displaying the second content on the second e-ink screen:

[0124] The system determines the adjustment mode of the e-ink device, which can be either synchronous adjustment of two screens or independent adjustment of two screens; it receives adjustment operations for the display mode of the first e-ink screen; when the adjustment mode is synchronous adjustment of two screens, it adjusts the display modes of the first and second e-ink screens based on the adjustment operations; when the adjustment mode is independent adjustment of two screens, it adjusts the display mode of the first e-ink screen based on the adjustment operations.

[0125] In some implementations, the adjustment operation is used to adjust one or more of the following: font, font size, page margins, paragraph spacing, and line spacing of the content displayed on the first e-ink screen.

[0126] In one possible implementation, the adjustment mode can be set by the user according to their reading needs.

[0127] In one possible implementation, under dual-screen synchronous adjustment, any display mode adjustment operation performed on one e-ink screen will be simultaneously applied to the other e-ink screen, ensuring that the display parameters of the two screens are completely consistent.

[0128] It should be noted that under dual-screen synchronous adjustment, if an adjustment operation is received for the display mode of the first e-ink screen, the display mode of the first e-ink screen can be adjusted first, and then the display mode of the second e-ink screen can be adjusted. This can avoid excessive instantaneous power consumption caused by simultaneous refresh of both screens, reduce the probability of ghosting caused by synchronous refresh of the e-ink screen, and allow users to see the adjustment effect of the first e-ink screen first, and then update the second e-ink screen synchronously, improving the visual smoothness and operation experience of the adjustment process.

[0129] In one possible implementation, under independent dual-screen adjustment, the display mode adjustment operation performed on one e-ink screen only applies to that e-ink screen, while the display parameters of the other e-ink screen remain unchanged.

[0130] In one possible implementation, the adjustment operation is an operation initiated by the user on the first e-ink screen to adjust the display effect. The adjustment operation is used to optimize the reading visual experience. It should be noted that the adjustment operation can also be an operation initiated by the user on the second e-ink screen to adjust the display effect. This application embodiment takes an operation initiated by the user on the first e-ink screen to adjust the display effect as an example for illustration.

[0131] In one possible implementation, the visual presentation attributes of the content displayed on the e-ink screen can affect the user's reading comfort.

[0132] For example, when the adjustment mode is dual-screen synchronous adjustment and the font size of both the first and second ink screens is 14, if the adjustment operation is to adjust the font size of the first ink screen to 12, then the font size of the content displayed on the first ink screen will change from 14 to 12, and the font size of the content displayed on the second ink screen can also be changed from 14 to 12.

[0133] For example, when the adjustment mode is dual-screen independent adjustment, and the distance from the end of the text on both the first and second ink screens to the bottom of the screen is 10 centimeters (cm), if the adjustment operation is to adjust the distance from the end of the text on the first ink screen to the bottom of the first ink screen to 15cm, then the distance from the end of the text on the first ink screen to the bottom of the first ink screen changes from 10cm to 15cm, while the distance from the end of the text on the second ink screen to the bottom of the second ink screen remains unchanged at 10cm.

[0134] In this embodiment, by providing two flexible adjustment modes—dual-screen synchronous adjustment and dual-screen independent adjustment—users can initiate adjustments to multiple display parameters such as font, font size, and page margins on any e-ink screen. During synchronous adjustment, a step-by-step refresh logic is adopted, first for the main screen and then for the secondary screen. This not only meets the user's need for consistent parameters on both screens when reading side-by-side, but also adapts to scenarios where different content such as main text, annotations, and translations are displayed differently. At the same time, it reduces the device's instantaneous power consumption and the probability of e-ink screen ghosting, improving the personalized reading comfort and operational flexibility of e-ink screen devices.

[0135] Next, combined Figure 7 and Figure 8 The methods for adjusting the display mode based on the two adjustment modes are explained respectively.

[0136] For example, taking the first e-ink screen as the left screen, Figure 7 This is a schematic diagram illustrating how to adjust the display mode based on dual-screen synchronous adjustment, as provided in an embodiment of this application. Figure 7 As shown, the first e-ink screen displays the first content, and the second e-ink screen displays the second content. The distance from the end of the first content to the bottom of the first e-ink screen is 10cm, and the distance from the end of the second content to the bottom of the second e-ink screen is 10cm. In response to the user's adjustment of the distance from the end of the first content to the bottom of the first e-ink screen, the distance from the end of the first content to the bottom of the first e-ink screen is first adjusted to 15cm, and then the distance from the end of the second content to the bottom of the second e-ink screen is also adjusted to 15cm.

[0137] For example, taking the first e-ink screen as the left screen, Figure 8 This is a schematic diagram illustrating how to adjust the display mode based on independent dual-screen adjustment, as provided in an embodiment of this application. Figure 8As shown, the first e-ink screen displays the first content, and the second e-ink screen displays the second content. The distance between the end of the first content and the bottom of the first e-ink screen is 10cm, and the distance between the end of the second content and the bottom of the second e-ink screen is 10cm. In response to the user's adjustment of the distance between the end of the first content and the bottom of the first e-ink screen, the distance between the end of the first content and the bottom of the first e-ink screen is adjusted to 15cm, while the distance between the end of the second content and the bottom of the second e-ink screen remains at 10cm.
