[0002] As the functions of e-ink display terminals increase, more and more people have the need to install third-party applications on e-ink display terminals. However, most third-party applications that support handwriting on the market are only adapted to LCD or LED screens. Third-party applications need to have their underlying code modified to run on e-ink display terminals. This means that each third-party application needs to undergo a corresponding code modification adaptation process, making the operation of adapting third-party applications to e-ink displays extremely complicated. Summary of the Invention

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a display control method for an e-ink screen, the method being applied to an e-ink screen terminal, the method comprising: When the e-ink terminal starts up, a preset auxiliary monitoring service is started, and the auxiliary monitoring service is registered as an auxiliary service of the operating system of the e-ink terminal. In response to a click or touch event occurring in the user interface of a third-party application, the operating system sends the control attribute information corresponding to the click or touch event to the auxiliary monitoring service. The auxiliary monitoring service determines the handwriting function corresponding to the click or touch event based on the attribute information and the preset application configuration file database. In response to a handwriting event occurring in the user interface of a third-party application, the handwriting is displayed on the e-ink screen of the e-ink terminal based on the handwriting function and the handwriting event.

[0006] In one embodiment, the target configuration file defines the mapping relationship between the control class name and control number of each control and the handwriting function. The step of determining the handwriting function corresponding to the click or touch event in the target configuration file based on the control class name and the control number using the target application-specific processor includes: The target application-specific processor compares the control class name and the control number with the control class name and control number of each control in the target configuration file. Based on the comparison results, the handwriting function corresponding to the click or touch event is determined. The handwriting function includes: writing, writing pen type, writing pen width, and erasing.

Before the e-ink screen completes a full-frame refresh, the handwriting event and the handwriting data are used to control the e-ink screen to perform a local area refresh operation to display the handwriting.

[0008] In one embodiment, the step of controlling the e-ink screen to perform a partial area refresh operation based on the handwriting event and the handwriting data to display the handwriting includes: Based on the handwriting event, the target display area of ​​the handwriting on the ink screen is determined; The driver interface of the e-ink screen is invoked to generate a driving waveform for the target display area based on the handwriting data; Based on the driving waveform, the e-ink screen is controlled to perform a local area refresh operation on the target display area to display the handwritten handwriting.

[0009] In one embodiment, the method further includes: Obtain the application configuration file and application package name of each third-party application that can be applied to the e-ink terminal; The application package name and application configuration file of each third-party application are bound and stored in the e-ink terminal to obtain a preset application configuration file database.

[0019] Furthermore, the terms "first," "second," and "third" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0020] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art as described in the various embodiments of this application. The terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be construed as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0021] It is understood that the method of this application is applied to e-ink display terminals, which can be smart terminals, PC devices, etc. For ease of description, the following embodiments use e-ink display terminals as the execution subject for illustration.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a first embodiment of the display control method for an e-ink screen provided in this application. The method is applied to an e-ink screen terminal and includes: Step S101: When the e-ink terminal starts up, a preset auxiliary monitoring service is started, and the auxiliary monitoring service is registered as an auxiliary service of the operating system of the e-ink terminal.

[0024] In this embodiment, upon startup, the e-ink terminal immediately initiates a preset auxiliary monitoring service and registers this service as an auxiliary service of the e-ink terminal's operating system. The auxiliary monitoring service is a monitoring service program designed to enable the e-ink terminal to adapt to all third-party applications. This monitoring service program registers with the e-ink terminal's operating system's auxiliary services, allowing it to interact with the operating system and obtain relevant information. The e-ink terminal's operating system can be Android, iOS, Windows, etc.

[0025] Step S102: In response to a click or touch event occurring in the user interface of a third-party application, the operating system sends the control attribute information corresponding to the click or touch event to the auxiliary monitoring service.

[0026] In this embodiment, when a user uses a third-party application on an e-ink terminal, the user interface of the third-party application will be displayed on the e-ink screen of the e-ink terminal. In response to the click or touch event of the user interface of the third-party application, the e-ink terminal sends the control attribute information corresponding to the click or touch event to the auxiliary monitoring service through the operating system.

[0027] It's important to note that click or touch events are events triggered by the user on the user interface of a third-party application, activating corresponding controls. These events are ultimately captured by specific functions of the operating system, generating control property information. The operating system then sends this control property information to the auxiliary monitoring service. Third-party applications are those with handwriting recognition capabilities, such as drawing applications and notebook applications.

[0028] Step S103: Through the auxiliary monitoring service, determine the handwriting function corresponding to the click or touch event based on the attribute information and the preset application configuration file database.

[0029] In this embodiment, the e-ink terminal uses an auxiliary monitoring service to query a preset application configuration file database based on attribute information to determine the handwriting function corresponding to a click or touch event. The handwriting function includes writing and erasing. It should be noted that the preset application configuration file database is created and set in advance within the e-ink terminal, and it contains handwriting functions corresponding to various controls from different third-party applications.

[0030] Step S104: In response to a handwriting event occurring in the user interface of a third-party application, the handwriting is displayed on the e-ink screen of the e-ink terminal based on the handwriting function and the handwriting event.

[0031] In this embodiment, when a user performs a handwriting operation on the user interface of a third-party application displayed on the e-ink screen of the e-ink terminal, the e-ink terminal responds to the handwriting event occurring on the user interface of the third-party application and displays the handwritten handwriting on the e-ink screen of the e-ink terminal based on the handwriting function and the handwriting event. It can be understood that a handwriting event is the event corresponding to the user sliding their finger or using a stylus on the user interface. The handwriting event includes the position information of the finger or stylus sliding. The handwritten handwriting is the writing trace left by the user when performing a handwriting operation on the user interface; the handwritten handwriting can be a written trace or an erased trace.

[0032] In this embodiment, the e-ink terminal starts a preset auxiliary monitoring service upon startup and registers this service as an auxiliary service of the operating system. In response to click or touch events occurring in the user interface of a third-party application, the operating system sends the control attribute information corresponding to the click or touch event to the auxiliary monitoring service. The auxiliary monitoring service determines the handwriting function corresponding to the click or touch event based on the attribute information and a preset application configuration file database. In response to handwriting events occurring in the user interface of a third-party application, handwriting is displayed on the e-ink screen of the terminal based on the handwriting function and the handwriting event. By setting up an auxiliary monitoring service in the e-ink terminal, during the use of a third-party application, the auxiliary monitoring service monitors the application and, in conjunction with the preset application configuration file, determines the corresponding handwriting function and handwriting event. Simultaneously, handwriting is displayed on the e-ink screen based on the handwriting function and handwriting event, avoiding the need for third-party applications to modify their code to adapt to the e-ink screen and reducing the complexity of third-party application adaptation to e-ink screens.

[0033] Please refer to Figure 2 , Figure 2 The flowchart illustrates a second embodiment of the e-ink screen display control method provided in this application. The difference between the second and first embodiments lies in the step of sending the control attribute information corresponding to the click or touch event to the auxiliary monitoring service via the operating system in response to a click or touch event occurring in the user interface of a third-party application. This step includes: Step S201: In response to a click or touch event occurring in the user interface of a third-party application, the control attribute information corresponding to the click or touch event is obtained through the click or touch event monitoring function of the operating system.

[0034] In this embodiment, the e-ink terminal responds to click or touch events occurring in the user interface of a third-party application by obtaining the control attribute information corresponding to the click or touch event through the operating system's click or touch event monitoring function. It should be noted that the click or touch event monitoring function differs across operating systems; the function's purpose is simply to capture the control attribute information corresponding to the click or touch event.

[0035] In one embodiment, the operating system of the e-ink terminal is the Android system, and the click or touch event monitoring function of the Android system is the dispatchTouchEvent function in the View. That is, all click or touch events of the user interface of all applications in the Android system will eventually reach the dispatchTouchEvent function in the View. The control attribute information of the control that caused the click or touch event can be obtained in this function.

[0036] Step S202: The control attribute information is sent to the auxiliary monitoring service through the operating system.

[0037] In this embodiment, after capturing the control attribute information corresponding to a click or touch event, the operating system of the e-ink terminal sends the control attribute information to the auxiliary monitoring service. The auxiliary monitoring service is registered as an auxiliary service of the e-ink terminal's operating system, and can then interact with the operating system to obtain the corresponding control attribute information.

[0038] In this embodiment, the e-ink terminal captures control attribute information of controls triggered by click or touch events in the user interface of a third-party application through its own operating system. This control attribute information is then sent to the auxiliary monitoring service, which is pre-registered as an auxiliary service of the e-ink terminal's operating system. By directly using the native functions of the native system to capture and transmit control attribute information to the auxiliary monitoring service, and avoiding other methods of obtaining control attribute information for the auxiliary monitoring service, the ease of obtaining control attribute information for the auxiliary monitoring service is improved, thus increasing the efficiency of acquisition.

[0039] Please refer to Figure 3 , Figure 3 This is a flowchart illustrating a third embodiment of the e-ink screen display control method provided in this application. The difference between this third embodiment and the first to second embodiments is that the control attribute information includes: a third-party application package name, a control class name, and a control number. The step of determining the handwriting function corresponding to the click or touch event based on the attribute information and a preset application configuration file database through the auxiliary monitoring service includes: Step S301: Through the auxiliary monitoring service, instantiate the target application-specific processor in the preset application-specific processor library according to the third-party application package name.

[0040] In this embodiment, the e-ink terminal instantiates a target application-specific processor in a preset application-specific processor library based on the third-party application package name through an auxiliary monitoring service. It is understood that the preset application-specific processor library contains application-specific processors for various third-party applications, each bound to and stored with the corresponding third-party application package name. The auxiliary monitoring service can then query the application-specific processor library based on the obtained third-party application package name to determine the target application-specific processor and subsequently instantiate it.

[0041] It should be noted that the application-specific processor is a Processor class. The application-specific processor can query the target configuration file corresponding to the third-party application package name, and directly call the e-ink screen terminal's underlying operating system's dedicated e-ink screen rendering interface to display the corresponding handwriting.

[0042] Step S302: The target application-specific processor determines the target configuration file in the preset application configuration file database based on the third-party application package name.

[0043] In this embodiment, the e-ink terminal uses a dedicated processor for the target application to determine the target configuration file based on the third-party application package name in a preset application configuration file database. It is understood that the preset application configuration file database contains application configuration files for various third-party applications. Each application configuration file is bound to and stored with the corresponding third-party application package name. The application configuration file defines the handwriting functionality that each control in the third-party application (represented by a combination of control class name and control number) needs to respond to. The dedicated processor for the target application determines the target configuration file by querying the preset application configuration file database for the corresponding third-party application package name.

[0044] Step S303: Using the target application-specific processor, determine the handwriting function corresponding to the click or touch event in the target configuration file based on the control class name and the control number.

[0045] In this embodiment, the e-ink terminal uses a dedicated processor for the target application to determine the handwriting function corresponding to a click or touch event in the target configuration file based on the control class name and control number.

[0046] In one embodiment, the target configuration file defines the mapping relationship between the control class name and control number of each control and the handwriting function. The step of determining the handwriting function corresponding to the click or touch event in the target configuration file based on the control class name and the control number using the target application-specific processor includes: Step S3031: Using the target application-specific processor, the control class name and the control number are compared with the control class name and control number of each control in the target configuration file.

[0047] Step S3032: Based on the comparison results, determine the handwriting function corresponding to the click or touch event. The handwriting function includes: writing, writing pen type, writing pen width, erasing, erasing pen type, and erasing pen width.

[0048] In this embodiment, the e-ink terminal uses a dedicated processor for the target application to compare the control class name and control number with the control class name and control number of each control in the target configuration file. Based on the comparison results, the handwriting function corresponding to the click or touch event is determined. The handwriting function includes: writing, writing pen type, writing pen width, and erasing. It can be understood that the target application configuration file defines the handwriting function that each control in the third-party application needs to respond to through a combination of control class name and control number. By comparing the control class name and control number in the control configuration information with the control class name and control number of each control in the target configuration file, the handwriting function corresponding to the control class name and control number in the control configuration information can be located, that is, the handwriting function corresponding to the click or touch event.

[0049] In this embodiment, the e-ink terminal uses an auxiliary monitoring service to instantiate a target application-specific processor in a preset application-specific processor library based on the third-party application package name. The target application-specific processor then determines the target configuration file in a preset application configuration file database based on the third-party application package name. Based on the control class name and control number, it determines the handwriting function corresponding to the click or touch event in the target configuration file. This allows for rapid determination of the handwriting function corresponding to the click or touch event based on control attribute information including the third-party application package name, control class name, and control number, thus improving efficiency.

[0050] In one embodiment, such as Figure 4 As shown, Figure 4This application provides a timing diagram for the process from a user triggering a click or touch event to determining the handwriting function. When the e-ink terminal starts, an auxiliary monitoring service is initiated and registered as an auxiliary service of the e-ink terminal's operating system. In response to a click or touch event occurring in the user interface of a third-party application, the operating system sends the corresponding control attribute information (third-party application package name, control class name, and control number) to the auxiliary monitoring service. The auxiliary monitoring service instantiates an application-specific processor in a preset application-specific processor library based on the third-party application package name. The application-specific processor determines the configuration file in a preset application configuration file database based on the third-party application package name. The auxiliary monitoring service sends the control class name and control number to the application-specific processor, which then determines the handwriting function corresponding to the click or touch event in the configuration file based on the control class name and control number.

[0051] Please refer to Figure 5 , Figure 5 This is a flowchart illustrating a fourth embodiment of the display control method for an e-ink screen provided in this application. The difference between the fourth embodiment and the first to third embodiments is that the step of displaying handwritten strokes on the e-ink screen of the e-ink terminal based on the handwriting function and the handwriting event includes: Step S401: Generate handwritten data based on the handwriting function and the handwriting event.

[0052] In this embodiment, the e-ink terminal generates handwriting data based on handwriting functions and handwriting events. The handwriting data includes the writing pen type, writing pen width, erasing pen type, erasing pen width, and writing or erasing position. It can be understood that a handwriting event contains position information of the user's finger or stylus swiping on the user interface; this position information is the writing or erasing position in the handwriting data. The handwriting function includes: writing, writing pen type, writing pen width, and erasing. When the handwriting event is the user writing content on the user interface, the handwriting function selected by the user includes writing, writing pen type, and writing pen width; that is, the writing data corresponding to the written content includes writing pen type and writing pen width. When the handwriting event is the user erasing content on the user interface, the handwriting function selected by the user includes erasing, erasing pen type, and erasing pen width; that is, the writing data corresponding to the written content includes erasing pen type and erasing pen width.

[0053] Step S402: Call the ink screen's handwriting rendering interface. Before the ink screen completes a full-frame refresh, control the ink screen to perform a local area refresh operation based on the handwriting event and the handwriting data to display the handwriting.

[0054] In this embodiment, the e-ink terminal calls the e-ink's handwriting rendering interface through the target application's dedicated processor. Before the e-ink completes a full-frame refresh, it controls the e-ink to perform a partial area refresh operation based on handwriting events and handwriting data to display the handwriting. It is understood that due to the unique display principle of e-ink screens (relying on the movement of positive and negative electrons), handwriting on an e-ink screen typically requires at least one frame refresh (100-300ms) before it can be displayed, resulting in a poor user experience. This application, however, controls the e-ink to perform a partial area refresh operation based on handwriting events and handwriting data before the e-ink completes a full-frame refresh, thus achieving real-time display of handwriting and improving the user experience.

[0055] In one embodiment, the step of controlling the e-ink screen to perform a partial area refresh operation based on the handwriting event and the handwriting data to display the handwriting includes: Step S4021: Based on the handwriting event, determine the target display area of ​​the handwriting in the ink screen.

[0056] Step S4022: Call the driving interface of the e-ink screen to generate a driving waveform for the target display area based on the handwriting data.

[0057] Step S4023: Based on the driving waveform, control the e-ink screen to perform a local area refresh operation on the target display area to display the handwritten handwriting.

[0058] In this embodiment, the e-ink terminal, through a dedicated processor for the target application, determines the target display area of ​​the handwritten data on the e-ink screen based on the handwriting event. The target display area is the region on the e-ink screen where the handwriting event was triggered, and it is also the area where the handwriting needs to be displayed. The e-ink terminal, through the dedicated processor for the target application, calls the e-ink screen's driver interface to generate a drive waveform for the target display area based on the handwriting data. This drive waveform is a driving signal used to drive grayscale changes on the e-ink screen; different grayscale changes correspond to different drive waveforms. Based on the drive waveform, the e-ink terminal, through the dedicated processor for the target application, controls the e-ink screen to perform a partial area refresh operation on the target display area to display the handwriting. It can be understood that the drive waveform only controls the grayscale change of the target display area on the e-ink screen where the handwriting needs to be displayed, thus avoiding the need to refresh the entire e-ink screen, improving efficiency, and ultimately achieving real-time display of the handwriting, thereby improving the user experience.

[0059] In this embodiment, the e-ink terminal controls the e-ink screen to perform a partial area refresh operation based on handwriting events and handwriting data before the e-ink screen completes a full frame refresh, so as to display the handwriting and realize the real-time display of the handwriting, thereby improving the user experience.

[0060] Please refer to Figure 6 , Figure 6 This is a flowchart illustrating a fifth embodiment of the display control method for an e-ink screen provided in this application. The difference between the fifth embodiment and the first to fourth embodiments is that the method further includes: Step S601: Obtain the application configuration file and application package name of each third-party application that can be applied to the e-ink terminal.

[0061] Step S602: Bind the application package name and application configuration file of each third-party application and store them in the e-ink terminal to obtain a preset application configuration file database.

[0062] In this embodiment, before the e-ink terminal is put into use, the application configuration file and application package name of each third-party application applicable to the e-ink terminal are obtained. The application package name and application configuration file of each third-party application are then bound and stored in the e-ink terminal, resulting in a preset application configuration file database. This allows the e-ink terminal to quickly obtain the corresponding application configuration file based on the obtained control attribute information when responding to click or touch events.

[0063] Before the e-ink terminal in this embodiment is put into use, the application package name and application configuration file of each third-party application are bound and stored in the e-ink terminal to obtain a preset application configuration file database. This lays the foundation for the specific implementation process of the subsequent display control of the e-ink screen, so that when the e-ink terminal responds to a click or touch event, it can quickly obtain the corresponding application configuration file based on the obtained control attribute information, which helps to reduce the complexity of third-party applications adapting to the e-ink screen.

[0064] refer to Figure 7 , Figure 7 This is a schematic diagram of the display control device for the e-ink screen provided in this application. The display control device for the e-ink screen includes: The startup module 10 is used to start a preset auxiliary monitoring service when the e-ink terminal starts up, and to register the auxiliary monitoring service as an auxiliary service of the operating system of the e-ink terminal.

[0065] The acquisition module 20 is used to respond to click or touch events occurring in the user interface of a third-party application and send the control attribute information corresponding to the click or touch event to the auxiliary monitoring service through the operating system.

[0066] The determination module 30 is used to determine the handwriting function corresponding to the click or touch event based on the attribute information and the preset application configuration file database through the auxiliary monitoring service.

[0067] Display module 40 is used to respond to handwriting events occurring in the user interface of a third-party application and display handwritten strokes on the e-ink screen of the e-ink terminal based on the handwriting function and the handwriting events.

[0068] It is understood that the display control device of the e-ink screen in this embodiment corresponds to the display control method of the e-ink screen in the above embodiment. The options in the above embodiment are also applicable to this embodiment, so they will not be described again here.

[0069] This application also provides an e-ink display terminal, which, exemplary, includes a processor and a memory, wherein the memory stores a computer program, and the processor executes the computer program to enable the e-ink display terminal to perform the above-described e-ink display control method.
