As the electronic ink screen is similar to the eye protection characteristic of real paper, the wide application of various electronic ink screen devices and the derived note-taking purpose supporting a handwriting pen are promoted. However, due to the physical characteristics of the electronic ink screen, the screen refresh speed is relatively slow, so that the response time of the handwriting is much slower than that of the actual handwriting input, and the user experience is seriously influenced.
Based on this, the following technical solutions are proposed in the present application, specifically see the following:
in an embodiment, as shown in fig. 1, fig. 1 is a schematic flowchart of a screen updating method according to an embodiment of the present invention; the invention provides a screen updating method, which comprises the following steps:
s110: and when the fact that the user triggers the handwriting mode is detected, displaying a corresponding handwriting area in the screen.
In this step, when a user uses an electronic device, for example, uses a related application in the electronic ink screen device to perform a handwriting drawing operation, the electronic ink screen device provides a system interface for the related application, the system interface may be used to set the current application to enter or exit a handwriting mode, and the electronic ink screen device may further provide an interface to set a screen area allowing handwriting, that is, an allowed handwriting area, so that when it is detected that the user triggers the handwriting mode, a corresponding handwriting area may be displayed in the screen, so that the user performs a handwriting drawing operation in the handwriting area.
It can be understood that, the electronic ink screen device provided by the present application may have a plurality of different types of application programs installed therein, such as an application program for performing a handwriting drawing operation, and the application program may generate corresponding display information, such as handwriting, in response to the handwriting drawing operation of the user.
S120: a target handwriting pattern selected by a user in a handwriting mode is determined.
In this step, after the corresponding handwriting area is displayed in the screen through S110, the target handwriting style selected by the user in the handwriting mode may be determined, so as to perform a rendering operation on the real-time mobile data drawn by the user according to the target handwriting style.
The target handwriting style includes, but is not limited to, handwriting thickness, handwriting color, handwriting type, and the like, the handwriting thickness can be respectively graded by several grades, the handwriting color can be divided into various colors, such as red, yellow, blue, green, and the like, and the handwriting type can be divided into pens, pencils, ball pens, writing brushes, mark pens, and the like.
Further, when determining the target handwriting style selected by the user, the method may determine according to the handwriting thickness, the handwriting color and the handwriting type selected by the user in the application interface at present, may also determine according to the handwriting thickness, the handwriting color and the handwriting type selected in the user history data, and the like, and may also determine according to the default handwriting thickness, the handwriting color and the handwriting type in the application program under the condition that the user does not select the handwriting style.
S130: and receiving real-time mobile data drawn by a user in the handwriting area, and performing segmented rendering on the real-time mobile data based on the target handwriting style to obtain segmented handwriting data.
In this step, after the target handwriting style selected by the user in the handwriting mode is determined through S120, the application may receive real-time mobile data drawn by the user in the current handwriting area, and perform segment rendering on the real-time mobile data according to the target handwriting style selected by the user in the handwriting mode, so as to obtain segment handwriting data.
It is understood that the real-time movement data herein refers to a series of continuous or discontinuous point data drawn by the user in the handwriting area, the point data including, but not limited to, coordinate information, time information, pressure sensing information, etc. For the acquisition of the real-time mobile data, the real-time mobile data can be read through a stylus sensing device, and the touch point coordinates can also be read through a touch screen, which is not limited herein.
Further, the real-time mobile data drawn by the user in the handwriting area is received by the method, and the real-time mobile data is a series of continuous or discontinuous point data, so that the response speed of the screen is further improved, the method can perform segmentation processing on the real-time mobile data when handwriting rendering is performed, the data volume of the segmented real-time mobile data is small, the rendering efficiency of the segmented real-time mobile data is high when the segmented real-time mobile data is rendered, and the response speed of the screen can be effectively improved.
For example, when the real-time moving data is segmented, the segmentation may be performed according to coordinate information of a series of continuous or discontinuous point data, such as a set of point data with consistent abscissa as a segment of real-time moving data, or a set of point data with consistent ordinate as a segment of real-time moving data; or performing segmentation processing according to pressure sensing information of a series of continuous or discontinuous point data, for example, using a set of point data of which the pressure value range in the pressure sensing information is within a certain set range as a segment of real-time moving data; the data may be segmented according to time information of a series of continuous or discontinuous point data, for example, according to the time sequence, a set of point data in a certain set time range is used as a segment of real-time mobile data. Other modes capable of implementing the segmentation processing in the present application can be taken as preferred schemes in the present application, and are not limited herein.
Furthermore, after the real-time mobile data is segmented, the segmented real-time mobile data can be rendered according to a predetermined target handwriting pattern, so that the segmented handwriting data is obtained.

For example, an interactive interface of each application program, such as an interactive interface of an application program capable of performing a handwriting drawing operation, may be displayed on an ink screen of the electronic ink screen device, and a handwriting drawing component and a parameter control component provided by the application program may be displayed in the interactive interface. The handwriting drawing component can be used for receiving handwriting drawing operation and determining real-time moving data corresponding to the handwriting drawing operation; and the parameter control component can be used for setting handwriting styles, such as handwriting thickness, handwriting color, handwriting type and the like. After the application program receives the real-time mobile data and the target handwriting style through the handwriting drawing component and the parameter control component, the target handwriting style can be utilized to perform segmented rendering on the real-time mobile data, and segmented handwriting data obtained after segmented rendering is updated to a screen buffer area, so that a screen is updated through the segmented handwriting data stored in the screen buffer area.
It is understood that the screen buffer in this application refers to a memory map corresponding to the pixel content of the display. For example, when the display resolution is 1920x1080, it includes 1920x1080 pixel data, and the corresponding screen buffer is a memory area including 1920x1080 pixel data, and the pixel data generally refers to a color value of the pixel, for example, the ARGB32 format is a color value occupying 4 bytes.
According to the method and the device, in order to improve the display efficiency of the screen and the running efficiency of the program, the generated segmented handwriting data can be put into the screen buffer area, and when the updating condition is met, the segmented handwriting data stored in the screen buffer area is displayed on the screen, so that the handwriting drawn on the screen by the user can be displayed in time.
In the above embodiment, when it is detected that the user triggers the handwriting mode, a corresponding handwriting area may be displayed in the screen, so that the user draws real-time mobile data in the handwriting area, and before receiving the real-time mobile data drawn by the user, a target handwriting pattern selected by the user in the handwriting mode may be determined first, and then the received real-time mobile data is rendered in segments according to the target handwriting pattern.
In one embodiment, the determining the target handwriting pattern selected by the user in the handwriting mode in S120 may include:
s121: when detecting that a user triggers a handwriting style selection instruction in the screen, acquiring a plurality of handwriting styles based on the handwriting style selection instruction, and displaying each handwriting style in the screen.
S122: receiving a handwriting style selected by a user in the screen, and taking the selected handwriting style as a target handwriting style.
In this embodiment, when determining the target handwriting style of the user, it may be detected whether the user triggers a handwriting style selection instruction in the screen, and if the handwriting style selection instruction is triggered, a plurality of pre-stored handwriting styles may be called according to the handwriting style selection instruction, and each handwriting style may be displayed in the screen for the user to select.
It can be understood that, since the handwriting styles in the present application include, but are not limited to, handwriting thickness, handwriting color, handwriting type, and the like, the handwriting thickness may be respectively in several grades, the handwriting color may be divided into various colors, such as red, yellow, blue, green, and the like, and the handwriting type may be divided into pens, pencils, ball pens, writing brushes, mark pens, and the like.
Therefore, when each handwriting style is displayed, the handwriting thickness of multiple levels can be displayed in the display area corresponding to the handwriting thickness, different color types are displayed in the display area corresponding to the handwriting color, and the handwriting of different types is displayed in the display area corresponding to the handwriting type, so that a user can conveniently select the corresponding handwriting thickness, the handwriting color and the handwriting type, and after the handwriting style selected by the user in a screen is received, the handwriting style can be used as a target handwriting style.
In one embodiment, the determining the target handwriting pattern selected by the user in the handwriting mode in S120 may further include:
s123: and when the handwriting mode selection instruction triggered by the user in the screen is not detected, taking the default handwriting mode as the target handwriting mode selected by the user in the handwriting mode.
In this embodiment, before the user draws the real-time mobile data in the screen, if it is not detected that the user triggers a handwriting style selection instruction, at this time, the default handwriting style may be used as a target handwriting style selected by the user in a handwriting mode, and the real-time mobile data is rendered in a segmented manner according to the target handwriting style.
The default handwriting style may be a handwriting style set in factory settings, or a handwriting style set by the user before the current handwriting operation, that is, the corresponding handwriting style is called according to the history of the user to perform segment rendering.

In this embodiment, when the real-time mobile data is rendered in a segmented manner, the real-time mobile data may be processed in a segmented manner according to the moving direction of the real-time mobile data, so as to obtain the segmented data, and then the segmented data is rendered according to the target handwriting style, so as to obtain the segmented handwriting data.
When the real-time moving data is segmented according to the moving direction of the real-time moving data, the real-time moving data with the consistent moving direction can be used as a segment of data to be segmented to obtain segmented data; further, the moving direction here may be the abscissa of the point data corresponding to the real-time moving data is consistent, the ordinate of the point data corresponding to the real-time moving data is consistent, or the time information of the point data corresponding to the real-time moving data is within the set time range, which is not limited herein.
In one embodiment, the method may further comprise:
s150: and storing the segmented handwriting data into a memory buffer area, and clearing the segmented handwriting data stored in the memory buffer area when detecting that the user exits the handwriting mode.
In the embodiment, after the segmented handwriting data are obtained, in order to avoid the possibility that the written handwriting in the screen is lost due to the fact that only the screen buffer area is used for temporary storage, the segmented handwriting data after segmented rendering can be stored in the memory buffer area, and when the user is detected to exit the handwriting mode, the segmented handwriting data stored in the memory buffer area are cleared.
It can be understood that all the segmented handwriting data drawn in the handwriting mode can be stored in the memory buffer area of the application, when the system enters the handwriting mode, a handwriting event in the handwriting area can be monitored, when the handwriting pen falls down, the handwriting drawing is started, the actual handwriting is drawn according to the set handwriting pattern along with the movement of the handwriting pen, when the handwriting pen is lifted, the handwriting drawing is stopped, and the segmented handwriting data generated in the whole process can be stored in the memory buffer area, so that the segmented handwriting data of the corresponding area can be called through the memory buffer area subsequently.
Further, the memory buffer area in the application may be a section of buffer area opened in the memory, or may be a buffer area in a stack form, and the buffer area is used as an area for storing the segmented handwriting data in the handwriting mode, and can backup all the segmented handwriting data in the handwriting mode for the need from time to time.
In one embodiment, the method may further comprise:
s160: when it is detected that the display information except the real-time mobile data in the screen needs to be updated, an update request is sent to the screen buffer area, so that the screen buffer area updates the display information according to the update request, and the updated display information is displayed on the screen.
In this embodiment, in the handwriting process, if the current application or another application in the electronic device needs to update the screen, that is, when it is detected that the display information in the screen except the real-time mobile data needs to be updated, an update request may be sent to the screen buffer, and after receiving the update request, the screen buffer updates the display information according to the update request and displays the updated display information in the screen.
For example, in the process of handwriting by the user, if the system display time needs to be updated, an update request may be initiated to the screen buffer, and the data in the screen buffer may be updated according to the update request, so that the data in the screen buffer is displayed in the screen when the screen is refreshed.
In one embodiment, after sending the update request to the screen buffer in S160, the method may further include:
