Fig. 1 is a flowchart of a handwriting display method for an ink screen device according to an embodiment of the present application, where the ink screen device includes an ink screen, a screen synthesizer, and a screen driving module, and the ink screen is used to implement display based on physical imaging of a entity. The screen compositor is used to fetch display data from the graphics buffer, which will correspond to the layers, and compose the final data stream (or composite image data) for transmission to the screen driver module. The graphics buffer is different from the screen buffer, which is layer-specific. The screen synthesizer may take two forms, for example, a software form: with the SurfaceFlinger decision in the android system, the GPU provides an operational capability hardware form: HWC (hwcomposer) module, which is realized by independent chips) can be used independently or matched with each other. The screen buffer refers to a memory map corresponding to the pixel content of the display. For example, when the resolution of the display is 1920×1080, it contains 1920×1080 pixel data, and the corresponding screen buffer is a memory area containing 1920×1080 pixel data, and the pixel data generally refers to a color value of the pixel, for example, the color value of the color value occupying 4 bytes in the ARGB32 format. Image data generated according to the movement data actually comprises pixel data of pixels of each screen, corresponding driving waveforms are matched from a waveform lookup table according to the image data, and a screen driving module outputs screen driving signals to the ink screen according to the driving waveform data, so that pigment particles on ink bags of the ink screen are driven to move, and imaging is achieved. The software/hardware used for driving the electronic ink screen can be an independent chip or can be software which is attached to the firmware of the electronic ink screen and used for converting display data into driving the electronic ink bag. If the current application or other applications in the electronic device need to update the screen, that is, when it is detected that the display information in the screen needs to be updated, an update request may be sent to the screen buffer at this time, and after the screen buffer receives the update request, the display data is updated according to the update request, so that when the screen is refreshed, the data in the screen buffer is displayed in the screen. The specific manner of use is a matter of routine skill in the art and will not be described in detail herein. Based on the above functional architecture, a data transmission schematic diagram in the handwriting process is displayed by further combining with a handwriting display method for an ink screen device, which is provided in the embodiment of the application and shown in fig. 2. The handwriting display method in the embodiment of the application, as shown in fig. 1, comprises the following steps:
S110, acquiring mobile data in real time, wherein the mobile data is touch data generated in the handwriting operation process.
The scheme aims at realizing the specific display of the writing handwriting generated in the handwriting operation process. In one writing operation, a writing drop operation, a writing movement operation, and a writing lifting operation are generally included, and when the writing drop operation is detected (for example, a touch signal performed in a handwriting input area of the third party application interactive interface is started to be received), the writing operation may be determined to be entered, and when the writing lifting operation is detected (for example, the touch signal is stopped to be received), the writing operation may be determined to be completed. From the detection principle of writing operation, each writing operation results in a set of coordinates of points that are set up with the plane in which the ink screen lies and are characterized based on the coordinate system.
Step S120, the mobile data is sent to a third-party handwriting application and a handwriting optimization component, so that the third-party handwriting application generates target handwriting display data according to the mobile data period and sends the target handwriting display data to the screen synthesizer; and the handwriting optimizing component generates simulated handwriting display data according to the mobile data period and sends the simulated handwriting display data to the screen synthesizer and the screen driving module.
And when the third-party handwriting application enters a handwriting drawing state, detecting handwriting operation performed on the ink screen aiming at the third-party handwriting application. When the handwriting operation is detected, the handwriting optimizing component continuously collects real-time moving data corresponding to the handwriting operation, namely, collects point data corresponding to the handwriting. Of course, the third-party handwriting application also collects point data corresponding to handwriting, processes the mobile data acquired according to the period to obtain target handwriting display data, sends the target handwriting display data generated in each period to the screen synthesizer, and generates the handwriting according to the currently set handwriting pattern and records the handwriting in the form of the target handwriting display data.
Before receiving real-time mobile data generated by writing operation of a user, a basic handwriting pattern corresponding to the third-party handwriting application can be determined, so that the handwriting optimization component can render the received point data according to the basic handwriting pattern. The handwriting patterns include, but are not limited to, handwriting thickness, handwriting color, handwriting type, etc., and the handwriting type may be classified into pen, pencil, ball pen, writing brush, mark pen, etc.
Similarly, when the subsequent third-party handwriting is applied to render the target handwriting display data, the target handwriting display data is also rendered according to the point data and the target handwriting style. The target handwriting style may be customized by the third-party handwriting application and/or user-adjusted on the third-party handwriting application interface. The target handwriting patterns are essentially determined by the third-party handwriting application, and in order to enable the display effect of the simulated handwriting and the target handwriting rendered by the third-party handwriting application to be close, corresponding basic handwriting patterns can be preset for each third-party handwriting application. Although the basic handwriting pattern is initially preset by the system, the user may further adjust the basic handwriting pattern. In general, the target handwriting style is a rendering operation for a third party handwriting application, and the base handwriting style is an operation for generating a simulated handwriting by the handwriting optimization component, which may be the same or may be significantly different. The handwriting optimizing plug-in obtains the handwriting style of the third-party handwriting application; correspondingly, the display style of the simulated handwriting display data corresponds to the handwriting style of the third-party handwriting application, and the specific correspondence can be complete correspondence or can be simplified to generally realize correspondence of handwriting outlines after the processing process.
Step S130: and when the screen driving module receives the simulated handwriting display data, updating the display picture of the ink screen according to the simulated handwriting display data.
In the scheme, a plurality of analog handwriting display data can be generated in one writing operation process, and after the analog handwriting display data are transmitted, the screen driving module drives the ink screen to enable the ink screen to display the analog handwriting first, and display handwriting pictures timely, so that a user has handwriting and hand-following use experience.
Step S140: when the screen synthesizer receives display data corresponding to each application, generating image data according to the display data and storing the image data in a screen buffer area; when the screen synthesizer receives the target handwriting display data, the screen synthesizer removes the analog handwriting display data received before, generates image data according to the target handwriting display data and stores the image data in the screen buffer area.
Step S150: and the screen driving module also acquires image data from the screen buffer area according to a preset refreshing frequency for displaying.
In this embodiment of the present application, the analog handwriting display data is simultaneously sent to the screen driving module and the screen synthesizer, and for the corresponding screen synthesizer, the display data is further obtained from at least one data source, and the display data is combined to obtain the synthesized image data, which is equivalent to the synthesized image data including the analog handwriting display data, where the synthesized image data is stored in the screen buffer, and the screen driving module may obtain the synthesized image data from the screen buffer. In the method, the screen buffer area is not locked, and other data sources (data sources input by non-handwriting operation) can update the display data according to the normal image display update flow. The display data of the screen synthesizer for merging operation comprises simulated handwriting display data, a handwriting layer corresponding to the simulated handwriting display data is a final layer, and when the final layer is merged, when the pixel points of the merged layer are overlapped with the pixel points corresponding to the simulated handwriting, color synthesis is carried out on the pixel points.
In a specific display process, as shown in fig. 2, the analog handwriting display data received by the screen driving module and the image data to be displayed, that is, the image data obtained from the screen buffer area, can be compared in a software or hardware mode, so that the image quality effect of final display is improved.
When the target handwriting display data corresponding to the current period is confirmed to be sent to the screen synthesizer, sending an instruction for obtaining image data to be displayed to the screen driving module, so that the screen driving module displays the image data generated according to the target handwriting display data in the screen buffer area. After the handwriting drawing operation is detected to be finished, the screen synthesizer and the screen driving module are informed of removing the analog handwriting display data after the corresponding pen lifting refreshing delay is applied to the third-party handwriting, in other words, the analog handwriting display data in the screen synthesizer and the screen driving module are cleaned. After the pen lifting refreshing time delay, the third-party handwriting application renders target handwriting display data, the target handwriting display data are sent to a screen synthesizer, the screen synthesizer synthesizes images, a screen buffer area is refreshed, the synthesized image data are stored in the screen buffer area, and a screen driving module reads and displays the image data from the screen buffer area, so that the target handwriting can be displayed on an ink screen finally.
In summary, based on an ink screen, a screen synthesizer and a screen driving module which are arranged in the ink screen device, the ink screen device acquires moving data in real time, wherein the moving data is touch data generated in the handwriting operation process; transmitting the mobile data to a third-party handwriting application and a handwriting optimization component so that the third-party handwriting application generates target handwriting display data according to the mobile data period and transmits the target handwriting display data to the screen synthesizer; the handwriting optimizing component generates simulated handwriting display data according to the mobile data period and sends the simulated handwriting display data to the screen synthesizer and the screen driving module; when the screen driving module receives the simulated handwriting display data, updating the display picture of the ink screen according to the simulated handwriting display data; when the screen synthesizer receives display data corresponding to each application, generating image data according to the display data and storing the image data in a screen buffer area; when the screen synthesizer receives the target handwriting display data, the screen synthesizer removes the analog handwriting display data received before, generates image data according to the target handwriting display data and stores the image data in the screen buffer area; and the screen driving module also acquires image data from the screen buffer area according to a preset refreshing frequency for displaying. By setting the use flow for the temporary simulation data and the final target data respectively, the screen buffer area is prevented from being locked in the process from the generation to the display of the simulation data, and the normal display of the display data generated by other applications in the handwriting display process is ensured.
Please refer to fig. 3 and fig. 4, which are respectively a flowchart of another handwriting display method for an ink screen device and a data transmission schematic diagram in a handwriting display process of another handwriting display method for an ink screen device according to an embodiment of the present application, where the ink screen device includes an ink screen, a screen synthesizer and a screen driving module, and as shown in fig. 3, the handwriting display method includes:
step S210, mobile data is acquired in real time, wherein the mobile data is touch data generated in the handwriting operation process.
Step S220, the mobile data are sent to a third-party handwriting application and a handwriting optimization component, so that the third-party handwriting application generates target handwriting display data according to the mobile data period and sends the target handwriting display data to the screen synthesizer; and the handwriting optimizing component generates simulated handwriting display data according to the mobile data period and sends the simulated handwriting display data to the screen driving module.
An optional implementation manner is that the handwriting optimization plugin acquires a handwriting style of the third-party handwriting application; correspondingly, the display style of the simulated handwriting display data corresponds to the handwriting style of the third-party handwriting application.
And step S230, when the screen driving module receives the simulated handwriting display data, updating the display picture of the ink screen according to the simulated handwriting display data.
Step S240, when the screen synthesizer receives display data corresponding to each application, generating image data according to the display data and storing the image data in a screen buffer area; when the screen synthesizer receives the target handwriting display data, the screen synthesizer removes the analog handwriting display data received before, generates image data according to the target handwriting display data and stores the image data in the screen buffer area.
Step S250, the screen driving module further obtains image data from the screen buffer according to a preset refresh frequency for displaying. When the target handwriting display data corresponding to the current period is confirmed to be sent to the screen synthesizer, sending an instruction for obtaining image data to be displayed to the screen driving module, so that the screen driving module displays the image data generated according to the target handwriting display data in the screen buffer area.
In general, the frequency of the mobile data sent to the handwriting optimizing component is the same as that of the frequency of the mobile data sent to the third-party handwriting application, the speed of the handwriting optimizing component for generating the simulated handwriting display data is higher, and the speed of the third-party handwriting application for generating the target handwriting display data is lower, but the display interval between the target handwriting display data and the corresponding simulated handwriting display data is basically ensured to be short in the normal processing process, and the display of the simulated handwriting display data can be basically ensured to be directly switched to the display of the corresponding target handwriting display data. However, in the actual display process, the process of synthesizing the image data by the screen synthesizer and the process of displaying the target handwriting display data are not necessarily completely synchronous, and in order to ensure that the display state corresponding to the simulated handwriting display data can be maintained to reach the target handwriting display data, the corresponding display process of the simulated handwriting display data needs to be controlled.
Specifically, the handwriting display method further includes: each handwriting optimizing component starts timing when receiving mobile data each time, and sends a refreshing instruction to the screen driving module when the timing reaches a preset delay time; correspondingly, in step S250, the process of the screen driving module further obtaining, according to the preset refresh frequency, the image data from the screen buffer area to display includes: when the screen driving module acquires the image data after receiving the analog handwriting display data, performing difference comparison on the analog handwriting display data and the acquired image data, keeping the display state of the analog handwriting display data, and displaying the part, which is not overlapped with the analog handwriting display data, in the acquired image data until the refreshing instruction is received; and when the screen driving module acquires the image data after receiving the refreshing instruction, removing display content corresponding to the simulated handwriting display data, and displaying according to the acquired image data until the simulated handwriting display data is received.
In the specific processing process, a delay time length is preset, the delay time length takes the total time length from the start of the mobile data receiving process of the third-party handwriting application to the synthesis of the generated target handwriting display data to the image data as a reference, in the timing process, the display state corresponding to the analog handwriting display data is unchanged, if the image data is received for display in the period, the screen driving module keeps the display state of the analog handwriting display data, the part, which is not overlapped with the analog handwriting display data, in the image data is displayed, according to the processing logic, whether the obtained image data is generated based on the target handwriting display data or not can be finally ensured to normally display the handwriting, and the display content corresponding to the analog handwriting display data is cleared when the timing is reached, and is directly switched to the formal display of the target handwriting display data. By the method, interruption of handwriting display caused by advanced full-screen refreshing and clearing when the image data of the analog handwriting display data is displayed without corresponding target handwriting display data is avoided. Of course, the screen driving module does not receive the analog handwriting display data, and the analog handwriting display data can be displayed directly according to the image data.
The main difference between the embodiment of the present application and the previous embodiment is that the analog handwriting display data in step S220 is only sent to the screen driving module, and the screen synthesizer does not have analog handwriting display data when performing picture synthesis, and if the screen driving module exists in the form of independent hardware, the screen driving module does not need to perform color synthesis on the basis of the acquired image data except performing basic display according to the analog handwriting display data, so that the processing efficiency can be effectively improved, and the energy consumption required by data processing can be reduced.
