Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating an electronic ink screen display method according to an exemplary embodiment, where the electronic ink screen display method is applied to an electronic device configured with an electronic ink screen, as shown in fig. 1, and includes the following steps.
In step S100, data to be displayed is acquired, and an attribute of the data to be displayed is determined.
In step S200, according to the attribute of the data to be displayed, an operating system file of the electronic device is processed, so that the data to be displayed is adapted to the electronic ink screen. The electronic ink screen is used for displaying data to be displayed.
Here, it should be noted that the electronic device in the embodiment of the present disclosure may be any device having a reading function that can provide contents such as numbers or images. Such as: electronic devices may include, but are not limited to: the mobile phone, the tablet computer, the electronic book reader, the MP3 (Moving Picture Experts Group Audio Layer-3) player, the MP4 player (MPEG-4Part 14), the laptop portable computer, the vehicle-mounted computer, the desktop computer, the set-top box, the smart television, the wearable device, and the like.
According to the display method of the electronic ink screen, when data (namely data to be displayed, such as videos, characters and the like) is displayed on a display interface of the electronic ink screen, an operating system file of electronic equipment is processed according to the attribute of the data to be displayed, so that the data to be displayed is matched with the electronic ink screen. Therefore, the operating system file of the electronic equipment is processed on the operating system level of the electronic equipment, so that the electronic ink screen is compatible with the data to be displayed, the adaptability of the electronic ink screen is improved, and the content ecology of the electronic ink screen terminal is enriched. And, compare in correlation technique, optimize the mode that comes the adaptation electronic ink screen to APP at the APP aspect, avoided all carrying out the operation of optimizing to each upper application software, this has just also effectively reduced research and development work load.
It should be noted that, when the operating system file of the electronic device is processed at the operating system level of the electronic device to implement compatibility of the electronic ink screen with data (i.e., data to be displayed) to be displayed by various applications (e.g., various APPs) loaded on the electronic device, the processing of the operating system file of the electronic device at the operating system level may include: adding a function (such as a function with a detection function) in the operating system file or modifying an original function (such as a display function) in the operating system file, so that when various functions in the operating system file are called to process data to be displayed, the processed data to be displayed can be adapted to an electronic ink screen of the electronic equipment.
That is, based on the operating system layer of the electronic device, processing the operating system file of the electronic device may include: and adding a set function in the operating system file, and calling the added function to process the data to be displayed (for example, intercepting a certain frame of data in the data to be displayed for displaying), so that the processed data to be displayed is matched with the electronic ink screen. The method can also comprise the following steps: and modifying the function (such as a display function) in the operating system file so that when the modified function is called to display the data to be displayed, the data to be displayed can be correspondingly processed based on the operation defined in the modified function.
Based on the foregoing, in one possible implementation manner, the attribute of the data to be displayed represents the display form of the data to be displayed. In the embodiment of the present disclosure, the attribute of the data to be displayed may include dynamic data. Here, it will be understood by those skilled in the art that dynamic data may be used to represent dynamically changing content, such as: video, audio, animation, etc. That is, the dynamic data may be data displayed in a video format or an animation format. Compared with dynamic data, the dynamic data is static data, and the static data can be single-sheet or single-frame images, characters and other contents.
When the attribute of the data to be displayed includes dynamic data, processing an operating system file of the electronic device according to the attribute of the data to be displayed, which may include:
calling a detection function preset in an operating system file, and detecting the update state of a storage unit of the electronic equipment through the detection function; the storage unit is used for storing data to be displayed.
And when the updating state of the storage unit is detected to be the updating stop state, reading the last frame data of the data to be displayed currently stored in the storage unit.
And pushing the last frame of data to the electronic ink screen for display.
That is, after a certain upper layer application software is loaded on an electronic device equipped with an electronic ink screen, in the process of using the application software, when data to be displayed is data displayed in a dynamic form, such as video, animation, and the like, due to the slow display update speed of the electronic ink screen, when the video, animation, and the like are pushed to the electronic ink screen for display, the update speed of the electronic ink screen does not reach the animation or the play speed of the video, and the phenomena of smear, flicker, or stutter are caused. Therefore, in order to enable dynamic data to be displayed normally on the electronic ink screen, in the embodiment of the disclosure, by calling a detection function in an operating system file of the electronic device, an update state of a storage unit for storing data to be displayed in the electronic device is detected by the detection function. When the updating state of the storage unit is detected to be updating stopping, the loading process of the data to be displayed in the storage unit is indicated to be finished, so that the last frame of data of the currently stored data to be displayed in the storage unit can be read at the moment, and the read last frame of data is pushed to the electronic ink screen for displaying.
The updating state (loading process) of the data to be displayed in the storage unit is detected, and after the data to be displayed stops updating, the last frame of data (namely, the final display image of the data to be displayed) in the data to be displayed is displayed on the electronic ink screen, so that the dynamic data and the electronic ink screen are adapted.
It should be noted that the detection function is pre-added to an operating system file of the electronic device, and the detection function is used to detect an update state of a storage unit (e.g., a display cache) in the electronic device, where the storage unit is used to store data to be displayed.
To more clearly explain the process of the embodiment of the present disclosure, referring to fig. 2, a part a of fig. 2 shows a schematic diagram of a related art, and a part b of fig. 2 shows a schematic diagram of an electronic ink screen display method according to an exemplary embodiment.
After a certain upper application software (APP) is loaded on the electronic device configured with the electronic ink screen, when the APP is used, an event (for example, playing a video or animation) is triggered by sliding or clicking, and the data to be displayed which needs to be displayed at this time is in a dynamic form. Referring to a portion a of fig. 2, in the related art, when displaying the dynamic data, each frame of data of the dynamic data is sequentially acquired (i.e., in a frame-by-frame reading manner), and after each frame of data is converted when the dynamic data includes color information (i.e., when the dynamic data is in a color form), each frame of data is sequentially displayed on the electronic ink screen. In the process, data reading operation needs to be performed for many times, and the current display interface of the electronic ink screen needs to be updated repeatedly, which occupies a large amount of system resources. Referring to part b of fig. 2, in the embodiment of the present disclosure, by detecting the update state of the dynamic data, only the last frame of data is read after the update of the dynamic data is completed, and after the last frame of data is processed accordingly (i.e., the color format is converted into the grayscale format), only the last frame of data is displayed on the electronic ink screen. In the process, only one data reading operation is needed, and only one updating operation is needed to be carried out on the current display interface of the electronic ink screen, so that system resources are effectively saved, and power consumption is reduced.
In one possible implementation, when the attribute of the data to be displayed is dynamic data, the dynamic data may include both a color form and a grayscale form. Meanwhile, the electronic ink screen displays by means of the movement of black and white ink drops under an electric field, so that the electronic ink screen has no color. Therefore, before pushing the last frame of data to the electronic ink screen for display, the method may further include:
it is determined whether the last frame data is in color form.
And when the data of the last frame is determined to be in the color form, removing the color information of the data of the last frame, and increasing the contrast of the data of the last frame so as to convert the data of the last frame from the color form to the gray form.
By confirming the color information of the last frame of data and when the last frame of data is determined to be in a color form (i.e., the last frame of data contains color information, such as in an RGB format or a YUV format), the last frame of data also needs to be processed to convert the last frame of data into a gray scale form because the electronic ink screen is not adaptable to the color image data. When the last frame data is subjected to conversion processing, the color information of the last frame data is removed, and the contrast of the last frame data is increased, so that the last frame data can be clearly and normally displayed on the electronic ink screen, and the normal display of the data to be displayed is ensured.
In a possible implementation manner, when the attribute of the data to be displayed includes dynamic data, the dynamic data may also be screen switching data generated by operations such as sliding, scrolling, or page turning. That is, the dynamic data may also be data of a switching process between a current display interface and a next display interface of the electronic ink screen, such as: data displayed in a sliding or scrolling manner. Therefore, in this case, processing the operating system file of the electronic device according to the attribute of the data to be displayed may further include:
and determining an operation mode corresponding to the data to be displayed.
And modifying the display function in the operating system file according to the operating mode so that the data to be displayed is matched with the electronic ink screen when the modified display function is called to display the data to be displayed.
Namely, the operation mode corresponding to the data to be displayed is determined, and then the display function in the operating system file is modified according to the determined operation mode, so that the data to be displayed can be normally displayed on the electronic ink screen when the modified display function is called to display the data to be displayed.
The modifying of the display function in the operating system file may be modifying the display function to only display data to be displayed corresponding to the display interface at the start and end of each operation in the operating mode.
Such as: when the operation mode corresponding to the data to be displayed is determined to be sliding, modifying a display function corresponding to the sliding operation in the operating system file (for example, closing or intercepting a sliding process defined in the display function corresponding to the sliding operation), that is, performing intercepting processing in the ontouchvent of the frame, so that when the display function corresponding to the sliding operation is called to perform display of the next display interface, the intermediate process of the sliding operation (that is, the action process of switching the current display interface to the next display interface) can be filtered, and the display content (that is, the data to be displayed) corresponding to the next display interface (for example, the display interface when the current sliding operation is finished) can be directly displayed. Similarly, when the operation mode is scrolling or page turning, the modification principle is the same as or similar to that under the sliding operation, and those skilled in the art can directly know the modification mode under the scrolling operation and the page turning operation from the modification mode under the sliding operation, so that the details are not described here.
Here, it should be noted that, when the dynamic data is content such as video or animation, the above-mentioned manner (i.e., modifying the display function in the operating system file) may be used for processing, and only the specific modified display function is different.
When the data to be displayed is dynamic data, the related display function in the operating system file is modified, the animation effect is accelerated or skipped, and the final picture is directly displayed, so that the low-speed characteristic of the electronic ink screen is adapted, the normal display of the data to be displayed on the electronic ink screen is ensured, and the adaptability of the electronic ink screen is improved.
In one possible implementation, the attribute of the data to be displayed may also include static data. As will be understood by those skilled in the art, the static data may be a single image or a single frame image, or may be one or a group of static text. That is, the static data is data displayed in a static state. When the attribute of the data to be displayed is static data, processing an operating system file of the electronic device according to the attribute of the data to be displayed, which may further include:
and calling an information acquisition function preset in the operating system file, and acquiring the color information of the static data through the information acquisition function.
And when the color information of the static data is colored, removing the color information of the static data, increasing the contrast of the static data, converting the color form of the static data into the gray form, and pushing the static data in the gray form to the electronic ink screen for display.
That is, by adding an information acquisition function for acquiring color information of static data in advance in an operating system file. Therefore, when the static data is displayed on the electronic ink screen, the color information of the static data is acquired by calling the information acquisition function in the operating system file. After the color information of the static data is acquired, whether the static data is in a color form or a gray form can be determined. If the static data is in a color form (such as an RGB format or a YUV format), the static data is converted into a gray form from the color form by removing the color information of the static data and increasing the contrast of the static data, and then the static data converted into the gray form is pushed to an electronic ink screen for display. This effectively ensures the display of static data in color on the electronic ink screen.
Here, it should be further noted that, when the static data is in a grayscale form, the static data can be directly pushed to the electronic ink screen for display without processing; the static data can also be processed in the above processing mode (i.e. removing color information and increasing contrast ratio), and then pushed to an electronic ink screen for display.
Through getting rid of color information to static data, the mode that increases the contrast is handled, has not only guaranteed the normal demonstration of static data on the electron ink screen, and the contrast when still effectively having improved static data display to the electron ink screen has improved the definition of data display simultaneously.
In one possible implementation, removing color information of the static data, and increasing the contrast of the static data may include:
based on the color information, differences between the colors in the color information are identified.
Different gray values are assigned according to different differences between the colors, so that the static data is converted from a color form to a gray form.
That is, different gray values are correspondingly distributed through different difference values among the static data, so that the static data can have clear contrast after being converted into a gray form, and the clear display is displayed on the electronic ink screen, thereby effectively ensuring the display quality and the display effect of the electronic ink screen.
In a possible implementation manner, before obtaining the data to be displayed and determining the attribute of the data to be displayed, the method may further include: determining whether a refresh indication is received, and determining a refresh mode when the refresh indication is received.
And calling a pre-added refreshing menu from the operating system file according to the refreshing mode, and refreshing the current display interface of the electronic ink screen according to the refreshing mode defined in the refreshing menu.
That is to say, when the current display interface of the electronic device is refreshed, the refreshing menu is called by adding the refreshing menu in advance in the operating system file, and the current display interface is refreshed according to the refreshing mode defined in the refreshing menu, so that the refreshing operation of the content which is required to be displayed on the electronic ink screen by the APP at the current stage is realized on the operating system layer. And the processing is not required to be carried out on the APP layer, so that the cost and the time for APP development are effectively reduced.
It should be noted that a plurality of refresh modes are defined in a refresh menu previously added to an operating system file. Each refresh mode corresponds to a different application scenario. Referring to table 1, table 1 shows different refresh modes corresponding to four different application scenarios.
In one possible implementation, the refresh mode comprises an automatic mode. In an automatic mode, calling a refresh menu added in advance from an operating system file, and refreshing a current display interface of the electronic ink screen according to a refresh mode defined in the refresh menu, wherein the refresh menu comprises the following steps:
and determining an application scene according to the data to be displayed. And the switching modes of the display interfaces in different application scenes are different.
According to the application scene, a matched refresh mode is determined from a plurality of refresh modes defined in the refresh menu.
And calling the matched refreshing mode, and refreshing the current display interface by adopting the matched refreshing mode.
The application scene is determined according to the data to be displayed, and then the matched refreshing mode is selected according to the determined application scene to refresh the current display interface, so that the current display interface of the electronic ink screen can be refreshed by adopting the most appropriate refreshing mode, the visual experience of the electronic ink screen during refreshing is further improved, and the refreshing effect is improved.
TABLE 1
In one possible implementation manner, determining an application scenario according to data to be displayed may include:
and analyzing the data to be displayed, and acquiring the characteristic information of the data to be displayed.
And determining the application scene according to the characteristic information.
Wherein the feature information includes at least one of OCR (Optical Character Recognition) Recognition information, text information, and image information.
Such as: by analyzing the data to be displayed, the feature information of the acquired data to be displayed only includes text information (that is, the data to be displayed is one or one segment of text), and then it can be determined according to the text information that the application scene can be "a pixel for displaying a new gray scale change, such as a fast page turning, a window jumping, a menu, a character number selection, a typing or a stylus input, a highlight mark (a reverse mode), a mouse pointer", that is, the application scene with an instruction set corresponding to DU 2. When the acquired feature information includes text information and image information, it may be determined that the application scene may be "providing an optimal picture display effect, and all pixels may be refreshed for displaying a high-quality picture, and fine text", that is, the application scene corresponding to the instruction set GC16, according to the feature information acquired at this time.
The method comprises the steps of analyzing data to be displayed, determining content to be displayed on a current display interface of an electronic ink screen, analyzing the content to be displayed, acquiring characteristic information of the data to be displayed, determining an application scene according to the acquired characteristic information, and ensuring the accuracy of determining the application scene, so that when a matched refresh mode is selected according to the application scene subsequently, the selected refresh mode is the most suitable and matched refresh mode, and the refresh effect is effectively guaranteed.
In one possible implementation, the refresh mode may also include a manual mode. In the manual mode, the method includes that a refresh menu added in advance is called from an operating system, and a current display interface of the electronic ink screen is refreshed according to a refresh mode in the refresh menu, and the method includes:
and calling the refreshing menu, and pushing the refreshing menu to the current display interface of the electronic ink screen.
And waiting for receiving a refresh mode determination instruction, and after receiving the refresh mode determination instruction, extracting a matched refresh mode from a plurality of refresh modes defined in the refresh menu according to the refresh mode determination instruction.
And refreshing the current display interface according to the matched refreshing mode.
That is, when the refresh mode is the manual mode, it indicates that the user selects the current refresh mode. Therefore, in a manual mode, when the current display interface of the electronic ink screen is refreshed, the refreshing menu in the operating system file can be called, the refreshing menu is pushed to the current display interface of the electronic ink screen, and the refreshing menu is displayed to a user by the electronic ink screen. The display mode of the refresh menu on the electronic ink screen may be a table mode or other modes, and is not limited specifically here. After the user selects the required refresh mode through the electronic ink screen, the user receives a refresh mode determination instruction containing the refresh mode information selected by the user, and then extracts the corresponding refresh mode according to the received refresh mode determination instruction to refresh the current display interface.
By setting a manual refreshing mode, a user can select a required refreshing mode to refresh the current display interface, so that the flexibility of refreshing the electronic ink screen is effectively improved.
In order to more clearly illustrate the process of the electronic ink screen display method according to the embodiment of the present disclosure, an application scenario is taken as an example to be more clearly described below.
Application scenario 1
The electronic equipment is a tablet computer, and a display screen of the tablet computer is an electronic ink screen. Wherein, an upper application software (video player) for watching video is loaded on the tablet computer, and the data stored in the database of the video player comprises dynamic data such as video, animation and the like. Meanwhile, the operating system of the tablet computer is an Android system (Android system), and a refreshing menu, a detection function, an information acquisition function and the like are added in advance in an operating system file.
Based on the above application example, in order to ensure that the data in the video player can be normally displayed on the display screen of the tablet computer (i.e. ensure that the video player is compatible with the display screen of the tablet computer), the following method may be adopted:
after the video player is opened on the tablet computer (i.e., after the video player runs on the tablet computer), the user performs a refresh operation of the current display interface by sliding the current display interface on the display screen. At this time, after the refresh instruction is received, the refresh mode is determined.
If the refreshing mode is automatic refreshing, the data to be displayed is obtained from the display cache of the tablet computer, the data to be displayed is analyzed, the characteristic information (such as OCR identification information, character information or image information) of the data to be displayed is obtained, and the corresponding application scene is determined according to the characteristic information. After the corresponding application scene is determined, according to the application scene, a matched refresh mode is determined from a plurality of refresh modes defined in a refresh menu, the matched refresh mode is called, and the current display interface is refreshed by adopting the matched refresh mode.
If the refreshing mode is manual refreshing, the refreshing menu is called at the moment, the refreshing menu is pushed to the current display interface of the electronic ink screen, and the user selects the required refreshing mode. After receiving the refresh mode determination instruction (namely, after the user selects the refresh mode), according to the refresh mode determination instruction, extracting a matched refresh mode from the plurality of refresh modes defined in the refresh menu, and refreshing the current display interface according to the matched refresh mode.
In the process of refreshing the current display interface, corresponding content (namely, data to be displayed) needs to be displayed on the display screen after refreshing. Therefore, at this time, the data to be displayed can be acquired from the display cache, and the attribute of the data to be displayed is determined.
When the attribute of the data to be displayed is determined to be dynamic data (namely, the content to be played by the video player currently is a video or animation and the like), a detection function in the operating system file is directly called, and the update state of the display cache is detected through the detection function. And when the update state is detected to be the update stop state, reading the last frame data of the data to be displayed currently stored in the display cache, and determining whether the last frame data is in a color form. And when the data of the last frame is determined to be in the color form, removing the color information of the data of the last frame, and increasing the contrast of the data of the last frame so as to convert the data of the last frame from the color form to the gray form. And then the last frame of data converted into the gray scale form is pushed to the electronic ink screen for display. At this time, the content displayed on the current display interface of the display screen of the tablet computer is the last frame of data (i.e., the final picture of the video or animation).
When the attribute of the data to be displayed is determined to be static data (namely, the content to be played currently by the video player is a static picture), an information acquisition function in an operating system file is directly called, and the color information of the picture is acquired through the information acquisition function. When the color information of the picture is a color (i.e., the picture is a color picture), the difference value between the colors in the color information is identified according to the color information, and different gray values are allocated according to different difference values between the colors, so that the picture is converted from a color form to a gray form (i.e., the color picture is converted into a gray picture). And after the picture is converted from the color form to the gray form, pushing the picture in the gray form to an electronic ink screen for display.
In summary, in the embodiment of the present disclosure, the operating system file is processed on the operating system level, so that the compatibility of the upper layer application software and the electronic ink screen is realized, the problem of display adaptation of the upper layer application software on the electronic ink screen is solved, and direct adaptation is performed without the participation of APP research and development personnel, which effectively enriches the application range of the electronic device configured with the electronic ink screen, and also effectively reduces the development cost, time and development workload of the application software.
