Description

Page refreshing method and electronic device

Technical Field

The present application relates to the field of display technologies, and in particular, to a method for refreshing a page and an electronic device.

Background

The electronic ink is a flicker-free and self-luminous display technology, and an ink screen developed based on the electronic ink has the obvious advantage of protecting eyes, and electronic equipment such as electronic books, electronic writing boards and electronic labels increasingly use the ink screen.

The ink drops in the ink screen are an electrochemical material, and display content is changed by virtue of movement of black and white ink drops under an electric field. Compared with electronic screens such as a liquid crystal display (liquid crystal display, LCD) or an organic light emitting semiconductor (organic electroluminescence display, OLED), the ink screen has a slower display update speed, and may have the phenomena of smear, delay, jamming, flickering, and the like.

As an important application scenario of the handwriting pen as an ink screen, the experience of using the handwriting pen by a user is poor due to delayed display of the handwriting pen, so how to solve the problem of handwriting pen delay is a urgent need in the field of ink screens at present.

It should be understood that the time corresponding to the global refresh refers to switching from the first page to the second page and displaying the second page entirely on the display screen. Illustratively, when the first page is switched to the second page and the second page is completely displayed, the refresh is required to be performed for 14 frames, that is, the global refresh corresponds to 14 frames, it should be understood that the second page may be displayed when the refresh time of the first page is switched to the second page is less than 14 frames, but the sharpness or color saturation of the second page displayed at this time may be lower than the second page displayed when the 14 frames are completely refreshed.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include, for example, "one or more" such forms of expression, unless the context clearly indicates to the contrary. It should also be understood that in embodiments of the present application, "one or more" refers to one or more than two (including two); "and/or", describes an association relationship of the association object, indicating that three relationships may exist; for example, a and/or B may represent: a alone, a and B together, and B alone, wherein A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship.

Reference in the specification to "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.

The plurality of the embodiments of the present application refers to greater than or equal to two. It should be noted that, in the description of the embodiments of the present application, the terms "first," "second," and the like are used for distinguishing between the descriptions and not necessarily for indicating or implying a relative importance, or alternatively, for indicating or implying a sequential order.

The page refreshing method of the ink screen is applied to the electronic equipment with the ink screen, and in the following description, if no special description exists, the electronic equipment is the electronic equipment with the ink screen. Exemplary, fig. 1 shows an exemplary scenario for application provided in the embodiment of the present application. As shown in fig. 1 (a), the electronic device 100 has an ink screen 101. Ink screen 101 may display pages of an Application (APP) installed in electronic device 100. Specifically, the ink screen 101 displays a display page 102 (page 1) and a display page 103 (page 2) of the APP. It should be appreciated that each APP contains multiple display pages, and when a user turns pages on the basis of display page 102, electronic device 100 jumps from display page 102 to display page 103, and the jump from display page 102 to display page 103 requires a global refresh of the electronic device.

As shown in fig. 1 (b), when the user performs a local operation on the display page 103, the electronic device may perform a local refresh on the display interface to display a page (page 104) after the local refresh on the display page 103. Illustratively, when the APP is of the reading type, after the user reads page 1 (page 102), the user turns page 2 (page 103), and when the user wants to make a note on page 2 (page 103), the user can edit on page 2 (page 103) in the form of a stylus or touch screen, and after the electronic device performs local refresh, the user can see the display page 104.

First, the concept of the ink screen mentioned in the embodiment of the present application will be specifically explained.

Exemplary, fig. 2 shows a schematic structural diagram of an ink screen according to an embodiment of the present application. Fig. 2 may be a plane view of the ink screen 101 in the AA' direction in fig. 1 (a) or fig. 1 (b). As shown in fig. 2, the ink screen includes a large number of ink droplets 13 therein. The ink droplets 13 are also called microcapsules (microcapsules) which have a size of about the size of the diameter of human hair. The ink droplet 13 contains a clear liquid, white particles 15 and black particles 16 suspended in the clear liquid, the white particles 15 having a positive charge, and the black particles 16 having a negative charge. The ink screen further comprises a top transparent electrode 11 and a bottom electrode 12 for applying an electric field to control the movement of white particles 15 and black particles 16 in the ink droplets 13.

For example, as shown in the ink droplet 13 on the left side in fig. 2, the electric field is set positive, the positive voltage is applied to the bottom electrode 12, the white particles 15 in the ink droplet 13 move toward the top of the ink droplet, i.e., toward the screen upward, so that the ink screen appears white to the user, and at the same time, the black particles 16 in the ink droplet 13 are pulled to the bottom of the ink droplet, thereby hiding.

For example, as shown in the ink droplet 13 on the right side in fig. 2, the electric field is set negative, the bottom electrode 12 applies a negative voltage, the black particles 16 in the ink droplet 13 move toward the top of the ink droplet, i.e., toward the screen upward, so that the ink screen appears black to the user, and at the same time, the white particles 15 in the ink droplet 13 are pulled to the bottom of the ink droplet, so as to be hidden.

It can be seen that the movement of white and black particles in the ink droplets can be controlled by the electric field applied by the top transparent electrode 11 and the bottom electrode 12, so that the ink screen can display color and display picture content. Wherein the colors include white, black, and gray levels (also referred to as gray levels) between white and black. The number of gray scales is not limited in the embodiment of the present application, for example, 2 gray scales, 16 gray scales, 32 gray scales, and the like.

The control chip of the ink screen may receive the control waveforms and apply an electric field to the top transparent electrode 11 and the bottom electrode 12 according to the control waveforms. Fig. 3 is a schematic diagram of a control waveform according to an embodiment of the present application. As shown in fig. 3, the control waveform has different voltage values at different time points, and the voltage values may be positive, negative or 0. The control waveform has a refresh frequency, which is also the frequency of refreshing the screen of the ink screen. The higher the refresh rate, the faster the picture refresh rate at the time of ink screen display, and conversely, the lower the refresh rate, the slower the picture refresh rate at the time of ink screen display.

Based on the display principle of the ink screen, the ink screen has the obvious advantages of low power consumption and eye protection. However, ink screens are typically slower to refresh when displayed, and the displayed color level is typically limited. When the ink screen displays animation, video and other contents, the situations of smear, jamming, flickering and the like may occur. The smear is also called afterimage, which is an afterimage on a display, and it can be understood that when the display switches the pictures, the previous picture does not disappear immediately, and the phenomenon that the previous picture and the next picture appear simultaneously and the previous picture disappear slowly appears on the visual effect.

To cope with different display scenes, the ink screen has a plurality of refresh modes. In different refresh modes, the control waveforms are different, for example, the frequency of the control waveforms is different and/or the voltage amplitude of the control waveforms is different, so that the requirements of different application scenes are met, and different display effects are provided.

Illustratively, the plurality of refresh modes includes: INIT (initial mode), DU (direct update), GC16 (gray level clear), GL16, GLR16, GLD16, and A2. The parameters for each refresh mode include: gray scale and refresh frequency.

The INIT mode is used to completely erase the display screen and keep it in a white state. It is suitable for display refresh in the case where the display information in the memory is not an indeterminate state of the optical element, e.g. a state after the device has been fully powered down after receiving power. This waveform will switch the display multiple times and place it in a white state.

A DU is a very fast, non-flashing update. For the DU refresh mode, there is 2 gray levels. This mode supports switching from any gray level to either black or white. It cannot be used for updating to any grey color other than black or white. The mode has fast updating time, and can be used for monochromatic menus, mouse pointers, text input, touch screen input, touch pen input, handwriting pen input, quick page turning, jump-out window, item selection (for example, word size selection), highlight marks and the like, little or no ghost shadow is generated, and the picture has no flicker.

The GC16 mode is used to update the full display and provide high image quality. The GC16 mode has 16 individual gray levels. When the GC16 is used with a full display update, the entire display will be updated as new images are written. If a "partial update" command is used, only pixels whose gray values change will be updated. Is generally used for displaying high-quality images, fine characters and the like, has little or no afterimage, and can provide a better picture display effect.

The GL16 waveform is mainly used to update sparse content on a white background, such as anti-aliasing, to reduce sparkle. The GL16 waveform has 16 unique gray levels.

The GLR16 refresh mode is generally used for displaying text, graphics, etc. in a white background, with little or no afterimage, and with little flicker during screen conversion.

The A2 mode is a fast, non-flashing update mode that can be used for fast page turning or simple black/white mode animation. For the A2 refresh mode, there is 2 gray levels, which only supports transitions from sum to black or white (meaning only black to white or white to black). It cannot be used for updating to any grey color other than black or white. Refresh is fast but contrast is poor, and is typically used for displays requiring fast refresh of scenes, such as fast page turning, video playing, animation, etc.

It should be noted that the above-mentioned refresh mode is only an example, and is not limited to the refresh mode, parameters of the refresh mode, application scenario, and display effect.

In order to facilitate understanding of the processing flow of display data of the electronic device, a general software architecture involved in displaying the electronic device is described. The software system of the electronic device may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, a cloud architecture, and the like. The embodiment of the application is described by taking a layered architecture as an example of electronic equipment. The layered architecture divides the software into a plurality of layers, each layer has clear roles and division, and the layers are communicated through software interfaces.

Fig. 4 is a schematic diagram of a software architecture of an electronic device according to an embodiment of the present application. As shown in fig. 4, the software architecture includes, from top to bottom, an Application (Application) layer, a framework (framework) layer, a Native Services layer, and a kernel layer.

The application layer, also referred to as the application layer, includes the APP provided by the system to the user, as shown in fig. 4, the application may be identified as APP 1-APP N, where N is a positive integer. Applications may include, but are not limited to: gallery, calendar, map, navigation, bluetooth, music, video, short message, etc.; the applications may also include third party applications such as: weChat reading, weChat, taobao, etc. APP 1-APP N can generate data to be displayed, and the electronic equipment processes the data to be displayed and then displays the data on the display screen. In this embodiment of the present application, the display screen is an ink screen.

The framework layer is also referred to as a framework service layer, and is used to provide application programming interfaces (application programming interface, APIs) and programming frameworks to application programs of the application layer. The framework layer may include some predefined functions, such as a layout subsystem and a rendering subsystem. The layout subsystem is used for realizing a layout flow, and the drawing subsystem is used for realizing a drawing flow.

The local service layer is used to provide the system level implementation required by the framework layer, such as graphics caching, database storage, etc. The local service layer may include a display composition subsystem for implementing a graph composition flow. For example, layers may be synthesized using an interface synthesis system (surfeflinger).

The kernel layer, also called the device driver layer, is the layer between hardware and software. The device driver layer includes at least display (display) drivers. In an embodiment of the present application, a waveform (waveform) module is further included for generating a control waveform. The control chip of the ink screen can apply an electric field according to the control waveform, so that the ink screen displays.

The electronic equipment processes the data to be displayed generated by the application program according to the display pipeline, and presents a display interface to the user. The display pipeline mainly comprises a layout flow, a drawing flow and a surfacefeldger synthesis flow. The layout process obtains the data to be displayed of at least one application program, and lays out the data to be displayed of each application program. And the drawing flow draws the content according to the layout corresponding to the data to be displayed of each application program, and generates a layer. And the surface eflinger synthesis flow synthesizes and displays a plurality of layers generated by the drawing flow, namely, the synthesized data is pushed to a display screen.

Next, an implementation of the page refresh mode of the ink screen in the related art will be described with reference to the scenario shown in fig. 1.

Fig. 5 is a schematic diagram showing an example of a structure of an ink screen apparatus in the related art, as shown in fig. 5, the ink screen apparatus including: a system on chip SOC, a timer control register Tcon, an electronic paper controller EPDC and an ink screen EPD. The main control devices such as a CPU and the like are integrated on the SOC and are main chips of the ink screen device; the Tcon is used for looking up a table according to the gray level image output by the SOC to obtain a driving waveform corresponding to the pixel. The SOC and the Tcon are electrically connected through an interface of a mobile industry processor (mobile industry processor interface, MIPI), and a grayscale image output from the SOC is transmitted to the Tcon. The EPDC is used for driving the ink particles in the EPD to move according to the driving waveform detected by the Tcon to realize imaging. However, when local refresh data is generated on a page, EPDC also needs to process the local refresh driving waveform after processing the global refresh driving waveform.

Optionally, the ink screen device further has an electromagnetic board, the electromagnetic board provides an electromagnetic handwriting function, a user can write any note content on the devices by using a handwriting pen, the electromagnetic board receives the induction data of the note, and finally the induction data can be processed to display the note content in the ink screen device, so that the user can conveniently mark in the reading process.

Fig. 6 shows a schematic flow chart of page refresh in the related art. As shown in fig. 6, when a user triggers a page turning operation, the electronic device performs global page refreshing, jumps from page 1 to page 2, performs synthesis of a layer corresponding to page 2 in a surface file, and then sends the synthesized layer to Tcon through an MIPI interface. The Tcon first performs gray processing on the image output in the surfacer, that is, converts the color image synthesized by the surfacer into a gray image. For example: the gray image can be obtained according to the gray value of each pixel point. And then, the Tcon looks up a table according to the gray image to acquire a driving waveform corresponding to the pixel position on the ink screen, and finally, the electronic equipment drives ink particles in the ink screen to move according to the driving waveform searched by the Tcon to realize imaging.

However, when the Tcon is still processing the globally refreshed data sent by the MIPI interface, the user triggers local refresh, and then the electronic device sends the image frame corresponding to the local brush (the position and the coordinate generated by drawing the handwriting pen) to the Tcon by using a universal serial bus interface (serial peripheral interface, SPI) channel, the Tcon firstly performs gray level conversion according to the local image frame to generate a gray level image, and then the Tcon obtains a driving waveform corresponding to the pixel according to the gray level image table lookup, and then the electronic device drives the ink particles in the ink screen to move according to the driving waveform searched by the Tcon to realize imaging.

Note that if the Tcon is processing the globally refreshed data sent by the MIPI interface, the data sent to the Tcon by the SPI needs to wait for a period of time before the Tcon can be processed, which eventually results in delay of the locally refreshed data displayed on the ink screen, and thus delay of the stylus pen. Illustratively, processing the data sent by the SPI requires waiting 500ms.

Fig. 7 shows another page refresh schematic in the related art. As shown in fig. 7, when a user triggers a page turning operation, the electronic device performs global refresh, and in the process of skipping from the page 1 to the page 2, a surface pointer in the electronic device first synthesizes a layer corresponding to the page 2, and then calculates a refresh area of the page 2 relative to the page 1. It should be appreciated that when the electronic device requires a global refresh, the refresh area is a global refresh area. And then, transmitting the calculated refreshing region to a hardware graphics renderer (hardware composer, HWC) by the surfacer, carrying out gray image transformation on the refreshing region by the HWC, and driving ink particles in an ink screen to move through an MIPI interface to realize imaging after obtaining a driving waveform corresponding to the pixel according to the gray image table lookup.

At the same time as the global refresh, the user triggers a local refresh, i.e. after the user performs a local operation on page 2, the electronic device performs the local refresh based on the user operation. In the process of jumping the page 103 to the page 104, a surface filter in the electronic device synthesizes a layer corresponding to the page 2 after partial refreshing, then calculates a refreshing area of the page 2 after partial refreshing relative to the page 2 before refreshing, finally, the surface filter transmits the partial refreshing area to the HWC, the HWC carries out gray image transformation on the refreshing area, and after a driving waveform corresponding to a pixel is obtained according to a gray image table lookup, ink particles in an ink screen are driven to move through an MIPI interface to realize imaging.

In this implementation manner, the global refresh and the local refresh are both performed by the HWC to perform gray image conversion first, and then the corresponding driving waveforms are searched according to the gray image, so when the global refresh is not completed yet, the local refresh needs to wait for the HWC to process the data of the global refresh when the local refresh is performed to refresh the data of the area, and therefore, the local refresh needs to wait, and finally, the handwriting pen is delayed. In addition, the chips corresponding to each APP are different, the HWC wants to finish page refreshing of a plurality of APP, and a plurality of different chips are required to be equipped, so that the cost is high and the resource is wasted finally.

In summary, whether the page refreshing method shown in fig. 6 or the page refreshing method shown in fig. 7 is adopted, the user needs to wait for the global refreshing to finish when the local refreshing is performed, and the handwriting pen scene is used as an important application scene of the local refreshing, and the handwriting pen is delayed due to the delay of the local refreshing, so that the user experience is poor. How to solve the response speed of the stylus pen is a problem in the field of ink screens.

In view of this, the present application provides a method for refreshing a page, in which global refresh and local refresh are performed simultaneously by inserting local refresh driving waveform conversion in the global refresh driving waveform conversion process, so as to solve the problem of local refresh delay caused by that the local refresh is performed only after the global refresh is completed in the related art, further improve the response rate of the local refresh, shorten the display time of the local refresh area, and improve the user experience.

The embodiment of the application does not limit the type, the model and the shape of the electronic equipment. Examples of some electronic devices are, for example: a wireless terminal in a cell phone, tablet, palm top, electronic book, electronic tablet, electronic sign, wearable device, smart screen, teaching device, internet of things (internet of things, IOT) device, or smart home (smart home), etc.

The page refreshing method provided by the embodiment of the application can be applied to the application scene shown in fig. 1, and can of course also be applied to other scenes, and the embodiment of the application is not limited.

Next, a software architecture of an electronic device implementing the page refreshing method provided in the embodiment of the present application is described.

The software of the electronic device 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In this embodiment, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated.

Fig. 8 is a software configuration block diagram of an electronic device according to an embodiment of the present application. The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into five layers, and as shown in fig. 8, the software architecture of the electronic device includes an application layer, a framework layer, a local service layer, a hardware abstraction layer and a kernel layer from top to bottom. The application layer, the framework layer, the local service layer, and the kernel layer may refer to the relevant descriptions in fig. 3, and are not described herein.

In this embodiment of the present application, the Surfaceflinger main thread in the local service layer is used to provide an image synthesis service, for example, to synthesize a layer after global refresh, or output a layer after local refresh. The Surfaceflinger main thread is also used to convert the synthesized color layer into a grayscale layer and output the grayscale layer to the HWC.

The surface active main thread in the local service layer comprises an electronic ink driving waveform (einkwave form) sub-thread which is mainly used for converting the gray level image into the driving waveform.

Specifically, when the einkwaveform sub-thread receives a locally refreshed waveform frame conversion task, the einkwaveform sub-thread may begin executing the locally refreshed waveform frame conversion while suspending the globally refreshed waveform conversion, and the locally refreshed waveform frame conversion times are the remaining globally refreshed waveform conversion times.

Alternatively, when the einkwaveform sub-thread receives a locally refreshed waveform frame conversion task, the einkwaveform sub-thread may begin executing the locally refreshed waveform frame conversion while suspending the globally refreshed waveform conversion, and the locally refreshed waveform frame conversion number is the number of times the entire page is refreshed.

A hardware abstraction layer (hardware abstract layer, HAL) is used to abstract the hardware. For example, the hardware abstraction layer may include an audio hardware abstraction layer, a bluetooth hardware abstraction layer, a camera hardware abstraction layer, a hardware renderer (hardware composer, HWC) abstraction layer, and other hardware device abstraction layers; the hardware renderer abstract layer can be connected with a hardware renderer algorithm library, and after graphic data are displayed on the device screen, the hardware renderer abstract layer can call algorithms in the hardware renderer algorithm library to render, and the hardware renderer is the core of all Android graphic rendering. The HWC in the hardware abstraction layer is also used to transfer the synthesized drive waveforms to the underlying drive.

The display driver in the kernel layer is used for driving ink particles in the ink screen to move according to the driving waveform to realize imaging.

Fig. 9 shows a schematic flowchart of an example page refreshing method provided in an embodiment of the present application. The page refreshing method provided by the embodiment of the application can be applied to the electronic equipment with the ink screen. As shown in fig. 9, the method 900 may include steps S910-S930:

s910, in response to user operation, the electronic device judges whether the current page needs local refreshing or global refreshing.

In the embodiment of the application, based on the operation of the user, the electronic device determines whether to perform the page skip on the current page or perform the local operation on the current page. It should be understood that the page skip corresponds to the electronic device performing a global refresh on the basis of the current page, and the local operation on the basis of the current page corresponds to the electronic device performing a local refresh on the basis of the current page.

Exemplary, fig. 10 shows an interface schematic diagram of a page refresh mode provided in an embodiment of the present application. If the current page is the second page, based on user operation, two possibilities exist on the basis of the second page, one possibility is based on page turning operation of the user, and the electronic equipment jumps to the third page after performing global refreshing on the basis of the second page; another is to display an update of the local area on the second page after the electronic device performs the local refresh on the basis of the second page, based on a local operation of the user, for example, the local operation may be taking notes, graffiti, etc. on the second page. Of course, the local operation may also be other manners, and the embodiments of the present application do not limit the manner of the local operation.

In some embodiments, the electronic device may obtain the operation signal by sensing movement of the handwriting pen through the electromagnetic plate, and then determine whether the user operation is a page skip or a local operation based on the page according to the operation signal.

For example, during the process of executing the handwriting operation by the user, the electromagnetic board monitors the handwriting report data generated by the handwriting operation, and generates new real-time report data in real time along with the handwriting operation by the user, and then the electromagnetic board detects the new real-time generated handwriting report data. The handwriting point data includes at least data reflecting tactile pressure, a position of the handwriting point, a dwell time of the handwriting point, and/or a thickness of the handwriting line, so as to determine handwriting content written by the handwriting operation. If the handwriting report data output by the electromagnetic plate is monitored, and the user is indicated to use the handwriting pen to execute handwriting operation, the user is in a handwriting use scene (local refreshing) corresponding to the update of the local area displayed on the basis of the second page in fig. 10. Otherwise, if a longer time has elapsed since the last time handwriting report point data was detected, it is considered that the global refresh is performed on the basis of the second page in fig. 9 corresponding to the non-handwriting use scene (global refresh).

In other embodiments, the electronic device may further determine whether the user operation is a page skip or a local operation based on the page according to the acquired graphic buffer.

It should be understood that, according to the drawing principle of the graphics system, whether the system is a built-in application or a third party application, a piece of graphics buffer is required to be applied from the BufferQueue for drawing the content of the application. Therefore, in the embodiment of the present application, the electronic device may determine, according to the GraphicBuffer obtained from the BufferQueue, whether the electronic device corresponding to the user operation needs global refresh or local refresh.

For example, based on user operation, if the GraphicBuffer acquired by the electronic device includes coordinates of a local area, the electronic device may determine that local refresh is needed on the basis of the current page. If the electronic device obtains the coordinates of the local area in the GraphicBuffer, the electronic device can determine that global refreshing is needed on the basis of the current page. Therefore, the electronic device can determine whether the electronic device performs global refreshing or local refreshing on the basis of the current page through the GraphicBuffer generated by user operation.

Illustratively, when the user's operation is to flip from the second page to the third page as shown in fig. 10, there is no coordinates of the local area in the GraphicBuffer; when the user's operation is as shown in fig. 10, the update contents are displayed in the local area on the second page, and there are coordinates of the local area in the GraphicBuffer. For example, the coordinates of the partial region may be coordinates where "notes" are located on the second page shown in fig. 10.

S920, when the current page needs local refreshing, stopping the driving waveform conversion of global refreshing, and converting the driving waveform of the local refreshing to the time corresponding to the global refreshing.

In the embodiment of the application, in order not to affect the waveform conversion of the local refresh, when receiving the waveform frame of the driving waveform conversion of the local refresh in the process of performing the driving waveform conversion of the global refresh, the electronic device can stop the waveform conversion of the global refresh and directly perform the waveform conversion of the local refresh, so as to reduce the display time of the local refresh area, thereby improving the efficiency of the local refresh of the electronic device.

It should be noted that, the time corresponding to the global refresh refers to switching from the first page to the second page, and the second page is completely displayed on the display screen. Illustratively, when the first page is switched to the second page and the second page is completely displayed, the refresh is required to be performed for 14 frames, that is, the global refresh corresponds to 14 frames, it should be understood that the second page may be displayed when the refresh time of the first page is switched to the second page is less than 14 frames, but the sharpness or color saturation of the second page displayed at this time may be lower than the second page displayed when the 14 frames are completely refreshed.

It should be understood that the Surfaceflinger may synthesize the GraphicBuffer after drawing the image data into the final image content, and display the final image content as the display information of the current page.

Therefore, in the embodiment of the present application, when the current page is locally refreshed, the electronic device sends the graphics buffer acquired in the BufferQueue to the Surfaceflinger in the electronic device, and then the Surfaceflinger synthesizes the layer of the locally refreshed current page according to the drawn graphics buffer. If the current page is the second page in fig. 10, the Surfaceflinger synthesizes the layer of the second page after the partial refresh according to the drawn GraphicBuffer.

Specifically, in the embodiment of the present application, the surface eflinger includes an app interface, where the app interface is configured to receive a drawn layer, for example, the app interface may receive a graphics buffer, and assuming that the frame rate is 1s/60 frames, the app interface receives a frame of the drawn layer every 16.67 ms; included in the surfeflinger is an appsf interface for synthesizing the received layers, for example, at a frame rate of 1s/60 frames, then appsf synthesizes the received layers once every 16.67 ms.

Based on the display principle of the ink screen, the electronic equipment also needs to perform graying treatment on the color image layer synthesized by the surface energy to obtain a gray image of the second page after local refreshing.

In one possible implementation, a Surfaceflinger in an electronic device may convert a color layer to a grayscale layer. Specifically, the surfacefelder may look up a table according to the gray value of each pixel point on the gray image to obtain a driving waveform corresponding to the pixel position on the ink screen. It should be appreciated that the transition of the drive waveform is also referred to as a transition of the waveform frame.

In this embodiment of the present application, after the electronic device obtains the gray image corresponding to the refreshed second page, the electronic device further needs to search and display the refreshed second page driving waveform according to the gray image, so as to complete final display.

Optionally, as a possible implementation manner, the einkwaveform sub-thread in the surfaefeldger main thread on the electronic device performs the conversion of the driving waveform.

Optionally, the surface Tcon interface may be further included in the surface active device, where the surface active device is used to find whether the conversion task of the locally refreshed waveform frame is sent, for example, the frame rate is 1s/60 frames, and the surface Tcon interface is found every 16 ms.

Optionally, the electronic device may also register a callback (callback) function in the einkwaveform sub-thread, where the callback function is used to receive a conversion task of a waveform frame in the create Tcon interface, and similarly, the callback function may also be received every 16 ms.

Therefore, when the einkwaveform sub-thread receives the transform task of the waveform frame, the waveform frame needs to be transformed. However, in general, when the einkwaveform sub-thread needs to convert a locally brushed waveform frame, the conversion of the fully brushed waveform frame by the einkwaveform sub-thread is not completed. In other words, when the electronic device needs to perform local area refresh of the second page, global refresh of the first page to the second page is ongoing. When the electronic device sends the gray image corresponding to the second page which is locally refreshed to the einkwaveform sub-thread, the einkwaveform sub-thread on the electronic device is converting the gray image which is globally refreshed from the first page to the second page into a driving waveform.

In this embodiment of the present application, the electronic device may stop the conversion of the globally refreshed waveform frame and directly perform the conversion of the locally refreshed waveform frame. It should be appreciated that a locally refreshed wave form frame is converted to continue conversion corresponding to a wave form frame of the global region, whereas a wave form frame of the local region is converted to begin conversion at the time of conversion of the locally refreshed wave form frame. In other words, the conversion of the locally refreshed wave form frame corresponds to the conversion of the wave form frame in which the global refresh is also performed.

For ease of understanding, further description is provided in connection with fig. 10 and 11. Fig. 11 is a schematic diagram illustrating an example of driving waveform conversion provided in the embodiment of the present application, as shown in fig. 11, when a surface active main thread in an electronic device sends a gray image corresponding to a locally refreshed second page to a einkwave form sub-thread, the einkwave form sub-thread on the electronic device performs conversion from a gray image of a first page to a gray image of a second page to a driving waveform. In other words, when a full-brush wave form frame needs to be converted, the full-brush wave form frame is being converted. Also, as can be seen from fig. 11, when a partially brushed wave form frame needs to be converted, the full brushed wave form frame has completed conversion of 8 frames.

It should be appreciated that in this example, a waveform frame complete 14 frame transition indicates that the waveform transition from the first page to the second page full brush is complete. Then, when the einkwaveform sub-thread receives the waveform frame to be converted of the local brush, the full-brush waveform frame does not complete conversion, but the full-brush waveform frame does not wait for the conversion of the full-brush waveform frame to complete and then performs conversion, but performs conversion of the full-brush waveform frame directly after the 8 th frame of the full brush. I.e., beginning at frame 9, the transition of the office swipe frame is initiated. Corresponding to the 1 st to 6 th frames of the partial brush being completed at the same time as the 9 th to 14 th frames of the full brush are completed.

In the implementation manner, the conversion of the drive waveform of the local brush can be directly inserted in the process of converting the overall drive waveform of the electronic equipment, so that the conversion of the drive waveform of the local brush is not influenced, the local display content corresponding to the local operation of the user can be rapidly displayed, and the user experience is improved.

And S930, the electronic equipment displays the page after the local refreshing according to the driving waveform of the global refreshing and the driving waveform of the local refreshing.

In the embodiment of the present application, the driving waveform of the page after the partial refresh may be generated based on the switching manner of the driving waveform in step S920.

And the electronic equipment drives ink particles in the ink screen to move based on the driving waveform to realize imaging, namely, finally, the page after the partial refreshing is displayed on the display interface.

According to the method provided by the embodiment of the application, the conversion of the drive waveform of the local brush can be directly inserted in the process of converting the drive waveform of the global drive waveform of the electronic equipment, so that the conversion of the drive waveform of the local brush is not delayed, the local display content corresponding to the local operation of the user can be displayed rapidly, and the user experience is improved. However, because the method of refreshing a page provided by the method 900 does not pass through a complete refresh cycle, the display effect of the page after the partial refresh displayed by the method 900 is not very good. Therefore, the embodiment of the application provides another page refreshing method, which ensures the efficiency of local refreshing and simultaneously ensures that the local refreshing can pass through a complete refreshing period.

Another method for refreshing a page according to the embodiment of the present application shown in fig. 12 is specifically described below. Fig. 12 shows a schematic flowchart of another example of a method for page refresh according to an embodiment of the present application, and the method 1200 mainly includes steps S1210-S1230.

S1210, responding to user operation, and judging whether the current page needs local refreshing or global refreshing by the electronic equipment.

Step S1210 may refer to the description of step S910, and will not be described herein.

S1220, when the current page needs local refreshing, stopping the driving waveform conversion of global refreshing, and ending the driving waveform conversion of executing local refreshing until the time corresponding to the local refreshing.

In the embodiment of the present application, when the einkwaveform sub-thread receives the task of converting the waveform frame, the waveform frame needs to be converted. However, in general, when the einkwaveform sub-thread needs to convert a locally brushed waveform frame, the conversion of the fully brushed waveform frame by the einkwaveform sub-thread is not completed. In other words, when the electronic device needs to perform local area refresh of the second page, global refresh of the first page to the second page is ongoing. When the electronic device sends the gray image corresponding to the second page which is locally refreshed to the einkwaveform sub-thread, the einkwaveform sub-thread on the electronic device is converting the gray image which is globally refreshed from the first page to the second page into a driving waveform.

In this embodiment of the present application, the electronic device may stop the conversion of the globally refreshed waveform frame and directly perform the conversion of the locally refreshed waveform frame. Unlike step S920, step S1220 performs a complete transition process, i.e., the transition of the driving waveform for performing the partial refresh to the end of the time corresponding to the partial refresh, when performing the transition of the waveform frame of the partial refresh.

For ease of understanding, further description will be given by taking fig. 13 as an example. Fig. 13 is a schematic diagram illustrating another embodiment of driving waveform conversion provided in the embodiment of the present application, as shown in fig. 13, when a surface active main thread in an electronic device sends a gray image corresponding to a locally refreshed second page to a einkwaveform sub-thread, the einkwaveform sub-thread on the electronic device is performing conversion from a gray image of a first page to a gray image of a second page to a driving waveform. In other words, when a full-brush wave form frame needs to be converted, the full-brush wave form frame is being converted. Also, as can be seen from fig. 13, when a partially brushed wave form frame needs to be converted, the full brushed wave form frame has completed conversion of 8 frames. Then, at this time, after the einkwaveform sub-thread receives the waveform frame to be converted of the local brush, the local brush waveform frame does not wait for the conversion of the full brush waveform frame to be completed, but directly performs the conversion of the local brush waveform frame after the 8 th frame of the full brush. I.e., starting at frame 9, starts the transition of the office swipe frame and recounts until the end of a complete cycle. Corresponding to the first frame through 14 th frame of the partial brush being completed after the 1 st through 8 th frames of the full brush are completed.

In the implementation manner, the conversion of the drive waveform of the local brush can be directly inserted in the process of converting the drive waveform of the global drive waveform of the electronic equipment, so that the conversion of the drive waveform of the local brush is not delayed, the conversion of the drive waveform of the complete local brush is executed, and the quality of a display picture is ensured while the local display content corresponding to the local operation of a user is rapidly displayed, so that the user experience is further improved.

S1230, the electronic device displays the page after the local refresh according to the driving waveform of the global refresh and the driving waveform of the local refresh.

The specific description of step S1230 may refer to step S930, and will not be described herein.

According to the method provided by the embodiment of the application, the conversion of the drive waveform of the local brush can be directly inserted in the process of converting the drive waveform of the global drive waveform of the electronic equipment, so that the conversion of the drive waveform of the local brush is not delayed, the conversion of the drive waveform of the complete local brush is executed, and the quality of a display picture is ensured while the local display content corresponding to the local operation of a user is displayed quickly, so that the user experience is further improved.

It should be noted that, the foregoing global page refreshing process in the method 900 and the method 1200 may refer to the specific description of the related art in the embodiments of the present application, or may refer to the global page refreshing process provided in the embodiments of the present application, which is not limited to this embodiment of the present application.

The global refreshing process provided in the embodiment of the present application is specifically described below. For example, reference may be made to fig. 10 of how an electronic device switches from a first page to a second page. Fig. 14 shows a schematic flowchart of a method for global refresh provided in an embodiment of the present application, and as shown in fig. 14, the method 1400 includes steps S1410 to S1430.

S1410, when the first page needs global refreshing to the second page, judging whether the first page is displayed completely.

In this embodiment of the present application, when the electronic device determines that the first page needs to be globally refreshed, that is, when the first page needs to be globally refreshed to the second page, based on the operation of the user, the electronic device needs to determine whether the sending task of the first page is completed.

It should be appreciated that refreshing of each page requires multiple waveform frames to be displayed completely clear on the page. Only if the transition of the plurality of waveform frames on the second page is completed, the transition of the locally refreshed waveform frames of the second page can be started.

Therefore, it is possible to determine whether the first page is completed by determining whether the wave form frame displaying the first page is converted to be sent.

S1420, when the first page is displayed, determining a driving waveform of the second page according to the image data of the second page.

It should be understood that when the first page on the electronic device completes display, based on user operation, the electronic device starts refreshing the second page, so that the electronic device sends the acquired GraphicBuffer to the surface processor to perform layer synthesis. And then obtaining a synthesized image layer corresponding to the second page, and carrying out gray-scale treatment on the synthesized color image layer based on the display principle of the ink screen to obtain a gray-scale image of the second page.

In one possible implementation, the grayscale image of the second page may be generated using a surfacefeldger in the first electronic device.

And according to the gray value of each pixel point on the gray image, looking up a table to obtain a driving waveform corresponding to the pixel position on the ink screen. It should be appreciated that this drive waveform is also referred to as a waveform frame.

In one possible implementation, embodiments of the present application utilize a einkwaveform sub-thread on an electronic device to convert a grayscale image to a driving waveform.

S1430, the electronic device displays the second page according to the driving waveform of the second page.

In the embodiment of the application, the einkwaveform sub-thread sends the converted driving waveform to the HWC, and the HWC renders and then sends the driving waveform to the display interface for page display.

That is, the electronic device performs a local operation on the second page during the process of refreshing from the first page to the second page, and thus the electronic device needs to complete the local refresh process during the global refresh process, which may refer to the above-mentioned method 900 and method 1200.

The page refreshing method provided by the application is described below with reference to another structure diagram. Fig. 15 shows a schematic flowchart of another page refreshing method provided in an embodiment of the present application. As shown in fig. 15, when the electronic device receives the refresh message, the electronic device reads a graphic buffer corresponding to the user click operation from the buffer request generated by the APP. And the electronic equipment judges whether the operation corresponding to the user on the current page is global refreshing or local refreshing according to the acquired graphicbuffer.

And when the coordinates of the local area are not included in the graphicbuffer, the operation corresponding to the user on the current page is indicated to be global refreshing. The electronic device judges whether the driving waveform frame of the last frame of the current page is sent, if the driving waveform frame of the last frame of the page is sent, the electronic device can refresh the current page, which indicates that the last page is displayed. The electronic device caches the globally refreshed graphicbuffer and then sends the graphicbuffer to the surfaceflinger main thread to perform layer synthesis, and it is understood that the synthesized layer is a color layer, and the surfaceflinger main thread needs to convert the color layer into a gray layer for displaying on the ink screen device. The electronic device sends the gray layer to the einkwaveform sub-thread to perform driving waveform conversion. Illustratively, as shown in FIG. 15, the electronic device is undergoing a transition from frame 1 to frame 8 of the global refresh.

When the graphicbuffer comprises the coordinates of the local area, the corresponding operation of the user on the current page is indicated to be local refreshing. The electronic device sends the acquired locally refreshed graphicbuffer to the surfaceflinger main thread to perform layer synthesis, and it is understood that the synthesized layer is a color layer, and the surfaceflinger main thread needs to convert the color layer into a gray layer for displaying on the ink screen device. The electronic device sends the gray layer to the einkwaveform sub-thread to perform driving waveform conversion. As shown in fig. 15, when the electronic apparatus needs to perform the transition of the drive waveform of the local refresh, the transition of the drive waveform of the global refresh is being performed, and in this case, the electronic apparatus suspends the transition of the drive waveform of the global refresh and performs the transition of the drive waveform of the local refresh. Illustratively, as shown in fig. 15, the electronic device pauses after performing the transition of the 8 th frame driving waveform of the global refresh, and starts performing the transition of the 1 st frame driving waveform of the local refresh. In this implementation, delays in local refresh can be avoided.

As shown in fig. 15, the Surfaceflinger main thread further includes an app interface, where the app interface is used for the Surfaceflinger to receive the drawn layer; included in the Surfaceflinger is an appsf interface for Surfaceflinger to synthesize the received layers. The surface file may further include a create Tcon interface, where the interface is used for the surface file to find whether a conversion task of the locally refreshed waveform frame is sent. The electronic device may also register a callback (callback) function in the einkwaveform sub-thread, through which a translation task of the waveform frame in the create Tcon interface is received.

The embodiments of the method for refreshing a page provided in the embodiments of the present application are described above in conjunction with fig. 9 to 15, and the electronic device provided in the embodiments of the present application is described below.
