Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a method, apparatus, electronic device, and storage medium for displaying multiple pages of a notebook. Background Technology

[0002] With the continuous development of electronic technology, electronic devices and applications developed for various specific application scenarios are increasingly involved in all aspects of people's lives, providing comprehensive support for each scenario. For example, when using mobile devices for reading and work, people often need to take handwritten notes. Users can input text on a touchscreen using their fingers or a stylus, or via a keyboard, to instantly record their thoughts.

[0003] In some situations, it's necessary to open at least two notebooks simultaneously for note-taking, meaning splitting the touchscreen into at least two windows, each displaying a separate note document. However, existing notebooks typically share a single editing toolbar and controls when multiple notes are displayed simultaneously. While this reduces the space occupied by the toolbar and controls, the editing modes and handwriting styles of the multiple notes may differ. This necessitates frequent manual switching of handwriting styles when recording multiple notes. The current notebook system's low level of automation undoubtedly adds inconvenience for users.

[0025] The display method provided in this application embodiment can be used in electronic devices equipped with touch screens. The electronic devices can be tablet computers, mobile phones, e-readers, personal digital assistants (PDAs), and other electronic devices based on touch screens. Specifically, the electronic devices may include touch screens, communication modules, digital signal processors, image processing modules, microcontrollers, screen driver modules, timing control circuits, and power control circuits.

[0026] The embodiments of this application will be described in detail below.

[0027] Figure 1 This is a flowchart of an embodiment of the method for displaying multiple pages of notes provided in this application. The method for displaying multiple pages of notes provided in this application can be executed by a display device, which can be implemented by hardware and / or software and integrated into an electronic device equipped with a touch screen.

[0028] The following description uses a display device to execute a method for displaying multiple instances of a notebook as an example. (Reference) Figure 1 A method for displaying multiple notes includes a touch screen displaying at least two note display areas, each note display area displaying a note document, each note including a handwriting style control, with at least two notes sharing a single handwriting style control, and the display method comprising: S10. Obtain the position of the handwriting tool on the touch screen.

[0029] The handwriting tool includes a stylus, which can be a capacitive stylus, an electromagnetic stylus, or a resistive stylus. The handwriting tool also includes a tool that enables handwriting input on a touchscreen display.

[0030] The point where the handwriting tool touches the touchscreen is the point where the handwriting tool first contacts the touchscreen.

[0031] Further, step S10 includes: S11. Obtain the pen stroke reporting data of the handwriting tool on the touch screen; S12. Obtain the pen placement position based on the pen placement data.

[0032] It is understood that the pen-point reporting data here includes the reporting data formed by the first contact between the handwriting tool and the touch screen, as well as some signal information. The reporting data includes, but is not limited to, coordinate information and time information. The pen-point reporting data can be acquired in real-time through the handwriting tool's sensing device or by reading the touch screen coordinates; no limitation is made here. Therefore, this application obtains the pen-point reporting data of the handwriting tool on the touch screen, wherein the pen-point reporting data includes coordinate information, and thus the pen-point position can be determined based on the pen-point reporting data. In addition, the pen-point reporting data may also include some signal information, which represent some commands input by the handwriting tool, such as handwriting input signals, erasing signals, and lasso signals.

[0033] S20. Obtain the first note whose display area overlaps with the pen placement position.

[0034] Specifically, by determining whether the coordinates of the pen placement position fall within the display area of ​​the first note, if so, the pen placement position overlaps with the first note; otherwise, the pen placement position does not overlap with the first note.

[0035] S30. Set the handwriting style of the handwriting style control to the handwriting style of the first note.

[0036] When the handwriting tool's pen stroke falls within the corresponding area of ​​the first note, it indicates that the handwriting tool is ready to perform handwriting input within the first note. There are two scenarios: First, the user has just started handwriting input using the handwriting tool, and the first note is the user's first handwriting input; second, the user previously performed handwriting input on another note and has just switched to the first note. For the first scenario, automatically setting the handwriting style control to the handwriting style of the first note based on the pen stroke position reduces the inconvenience of manual switching. For the second scenario, when multiple notes are open, the user may perform handwriting input in different notes. Automatically setting the handwriting style control to the handwriting style of the first note based on the pen stroke position avoids frequent switching of handwriting styles when multiple notes are open, greatly improving the intelligence and ease of use of the note-taking system.

[0037] The handwriting style includes parameters such as brush type, stroke thickness, stroke color, stroke smoothness, and pressure sensitivity. The brush type can include fountain pen, ballpoint pen, pencil, calligraphy brush / fine brush, marker, highlighter, etc.

[0038] In summary, this application obtains a first note whose display area overlaps with the pen placement position, and then sets the pen style of the pen style control to the pen style of the first note. This achieves automatic setting of the pen style control to the pen style of the first note based on the pen placement information, eliminating the need for manual switching and greatly improving the intelligence and ease of use of the note-taking system.

[0039] Furthermore, in Figure 1 Based on the provided display method, in one embodiment of this application, the touch display screen is a touch e-ink screen, and the handwriting style includes brush types, with each brush type corresponding to a refresh mode of the touch e-ink screen; The step of setting the handwriting style of the handwriting style control to the handwriting style of the first note includes: Set the handwriting style of the handwriting style control to the handwriting style of the first note, and set the refresh mode of the display area of ​​the first note to the refresh mode corresponding to the brush type of the first note.

[0040] In this embodiment, each brush type corresponds to a refresh mode on the touch e-ink screen. Since different brush types have different refresh display requirements, different refresh modes are used when the brush type of the notes is different. Therefore, this application improves the intelligence of the notes by simultaneously setting the refresh mode of the display area of ​​the first note to the refresh mode corresponding to the brush type of the first note when setting the handwriting style control to the handwriting style of the first note. This eliminates the need for manual refresh mode setting, thereby enhancing the user experience.

[0041] The refresh modes currently available for touch e-ink screens include: A2 refresh mode, DU refresh mode, GC refresh mode (including GC4, GC8, and GC16 refresh modes), GU refresh mode, GL refresh mode, and GLR refresh mode. Specifically: A2 refresh mode: Presents the previously displayed grayscale content in black and white to reduce the time and power consumption of rendering grayscale, resulting in the fastest refresh speed.

[0042] DU refresh mode: Presents the previously displayed grayscale content in black and white. The refresh speed is second only to A2 refresh mode, but the ghosting is less than that of A2 refresh mode.

[0043] GC refresh mode: All pixels are re-output. Before outputting, a screen clearing operation is performed. It can be further subdivided into GC4 refresh mode, GC8 refresh mode, and GC16 refresh mode, which indicate that it supports 4, 8, and 16 grayscale levels respectively. It has the slowest refresh speed but the least ghosting. GC refresh mode is also known as full-screen refresh, which means that the entire page is refreshed once, regardless of whether the grayscale of the same pixel has changed.

[0044] GU refresh mode: This mode does not clear the screen before outputting data, directly outputting pixels that have changed since the last output. This includes GU8 and GU16 refresh modes, which support 8 and 16 grayscale levels respectively. It is slower than A2 and DU refresh modes, but faster than GC refresh mode. GU refresh mode is also known as partial refresh; page turning speed is acceptable, and page changes are relatively smooth.

[0045] GL refresh mode: No screen clearing operation is performed before data output. It is generally GL16 refresh mode, which supports 16 grayscale levels. Its refresh speed is slower than A2 refresh mode and DU refresh mode, but faster than GC refresh mode. GL refresh mode is also a partial refresh.

[0046] GLR refresh mode: also known as "regal", it is generally GLR16 refresh mode, which supports 16 grayscale levels. Similar to partial refresh, the refresh method depends on the difference between the preceding and following images. The special feature is that if the preceding and following images go from black to black, there will be a black-white flashing effect. The refresh speed is similar to the aforementioned partial refresh mode, with less ghosting.

[0047] The current driving method for touch e-ink screens is as follows: The touch e-ink screen provides Waveform data based on the current refresh mode. Different refresh modes correspond to different Waveform data. Based on the Waveform data and the currently displayed image, the waveform sequence corresponding to the intermediate processes required for the next frame to be displayed is determined. Therefore, each refresh mode of the touch e-ink screen corresponds to a standard waveform, which is obtained by querying the Waveform data of the current refresh mode based on the current display image and the next frame to be displayed.

[0048] Furthermore, in Figure 1 Based on the provided display method, in another embodiment of this application, the touch display screen is a touch e-ink screen, the note includes a second cache unit, the second cache unit is used to store the latest refresh mode of the first note, and after the step of acquiring the first note whose display area overlaps with the pen placement position, the display method further includes: S40. Set the refresh mode of the display area of ​​the first note to the latest refresh mode of the first note.

[0049] In this embodiment, different note areas may employ different refresh modes because users may have different refresh requirements. For example, in some note display areas, users need to quickly refresh the display of handwriting and do not care about handwriting ghosting; therefore, a fast refresh mode is used in these areas. Conversely, in other note display areas, users do not need to quickly refresh the display of handwriting and require high display quality; in these areas, a slower refresh mode is used. Therefore, when a user switches between different notes, the refresh mode of the corresponding note display area needs to be switched simultaneously. This application automatically sets the refresh mode of the first note's display area to the latest refresh mode of the first note, avoiding the need for manual switching and improving intelligence and user experience.

[0050] Please refer to Figure 2 , Figure 2 A flowchart illustrating a second embodiment of the method for displaying multiple pages of notes provided in this application. Further, in Figure 1In addition to the provided display method, the display method further includes: S50. Obtain a second note whose display area does not overlap with the pen placement position; S60. Obtain the redraw driving waveform of the display area of ​​the second note according to the refresh mode of the display area of ​​the second note; S70. The second note is redrawn and refreshed using the redraw driving waveform.

[0051] The refresh mode used when redrawing and refreshing the second note may differ from the refresh mode used when handwriting input is performed on the second note. When the display area of ​​some notes is refreshed using a fast refresh mode during handwriting input, there may be significant display ghosting or insufficient particle drive on the touch e-ink screen. Both of these issues can lead to color distortion or poor display quality. Therefore, to improve the display effect of the second note, this application redraws and refreshes the display area of ​​the second note when the user performs handwriting input on the first note. The refresh mode used when redrawing and refreshing the second note can be a slower refresh mode, thereby improving the display effect.

[0052] Please refer to Figure 3 , Figure 3 A flowchart of Embodiment 3 of the method for displaying multiple pages of notes provided in this application. Further, in Figure 1 Based on the provided display method, the handwriting tool is a stylus, the note includes an eraser style control and a lasso style control, at least two notes share one eraser style control and one lasso style control, and before the step of setting the handwriting style of the handwriting style control to the handwriting style of the first note, the display method includes: S80. Based on the pen stroke reporting data, determine whether the stylus has triggered one of the three commands: handwriting input command, erase command, and lasso command. If the handwriting input command is triggered, proceed to the next step. S90. If an erase command is triggered, the erase style of the erase style control is set to the erase style of the first note. SA0. If the lasso command is triggered, the lasso style of the lasso style control is set to the lasso style of the first note.

[0053] In other words, in this embodiment, at least two notes share one erase style control and one lasso style control, which reduces the space occupied by the erase style control and lasso style control when multiple notes are open. Simultaneously, this application determines the handwriting style of the handwriting style control based on the pen stroke data. If the stylus triggers a handwriting input command, the handwriting style of the handwriting style control is set to the handwriting style of the first note; if the stylus triggers an erase command, the erase style of the erase style control is set to the erase style of the first note; if the stylus triggers a lasso command, the lasso style of the lasso style control is set to the lasso style of the first note. This achieves automatic setting of the parameters of the handwriting style control, erase style control, and lasso style control based on the pen stroke data, determining whether the stylus triggers one of the three commands: handwriting input, erase, or lasso. Furthermore, different notes may have different handwriting styles, different erasure styles, and different lasso styles. Therefore, this application can automatically set the handwriting style of the handwriting style control, the erasure style of the eraser control, and the lasso style of the lasso control, thereby improving the intelligence of note-taking and the user experience.

[0054] Furthermore, when the pen stroke reporting data includes a handwriting input signal, it is determined that the stylus has triggered a handwriting input command; when the pen stroke reporting data includes an erase signal, it is determined that the stylus has triggered an erase command; when the pen stroke reporting data includes a lasso signal, it is determined that the stylus has triggered a lasso command. That is, when the pen stroke reporting data includes a handwriting input signal, it means the handwriting tool has triggered a handwriting input command, and then the handwriting tool performs handwriting input on the touchscreen display; when the pen stroke reporting data includes an erase signal, it means the handwriting tool has triggered an erase command, and then the handwriting tool erases the pen strokes on the touchscreen display; when the pen stroke reporting data includes a lasso signal, it means the handwriting tool has triggered a lasso command, and then the handwriting tool performs lasso selection on the touchscreen display.

[0055] The erasure styles may include point erasure, lasso erasure, area erasure, and brush stroke erasure, and the lasso styles may include smart lasso, free lasso, circular / elliptical lasso, and rectangular lasso.

[0056] Please refer to Figure 4 , Figure 4 A flowchart of step S30 of the method for displaying multiple pages of notes provided in this application is shown in Embodiment 1. Further, in Figure 1Based on the provided display method, the note includes a first cache unit, which stores the latest handwriting style of the first note. The step of setting the handwriting style of the handwriting style control to the handwriting style of the first note includes: S31. Obtain the latest handwriting style of the first note from the first cache unit, wherein the handwriting style of the first note is the latest handwriting style of the first note; S32. Then set the handwriting style of the handwriting style control to the latest handwriting style of the first note.

[0057] That is, the first cache unit is used to store the latest handwriting style of the first note. Therefore, every time the handwriting style of the first note changes, the latest changed handwriting style will be stored in the first cache unit. Thus, the latest handwriting style can be the handwriting style that the user recently manually set for the first note and stored in the first cache unit, or it can be the handwriting style that the user last used to handwrite in the first note and stored in the first cache unit. In one embodiment of this application, when the handwriting style of the first note has not changed, the first cache unit can pre-store a preset handwriting style.

[0058] In summary, this application obtains the latest handwriting style of the first note from the first cache unit, and then sets the handwriting style of the handwriting style control to the latest handwriting style of the first note. By using the first cache unit to store the latest handwriting style of the first note, this application allows users to quickly obtain the handwriting style of the first note when switching between different notes, reducing the calculation process and enabling the handwriting style control to be quickly set to the handwriting style of the first note. Therefore, it can reduce switching latency and improve user experience.

[0059] Please refer to Figure 5 , Figure 5 A flowchart of step S30 of the method for displaying multiple pages of notes provided in this application, according to a second embodiment. Figure 4 Based on the provided display method, in one embodiment of this application, before the step of obtaining the latest handwriting style of the first note from the first cache unit, the display method further includes: S33. Determine whether the latest handwriting style of the first note is stored in the first cache unit. If so, proceed to the next step, i.e., execute step S31. S34. If not, obtain the handwriting style of the most recently closed first history note, the handwriting style of the first note is the handwriting style of the first history note, and then set the handwriting style of the handwriting style control to the handwriting style of the first history note.

[0060] In other words, when the first cache unit stores the latest handwriting style of the first note, the latest handwriting style of the first note is retrieved from the first cache unit, and then the handwriting style of the handwriting style control is set to the latest handwriting style of the first note. When the first cache unit does not store the latest handwriting style of the first note, it may mean that the first note is a newly created note or that the note style of the first note has not been changed. In this case, the handwriting style of the most recently closed first historical note is retrieved, and the handwriting style of the first note is used as the handwriting style of the first historical note. Then, the handwriting style of the handwriting style control is set to the handwriting style of the first historical note. Therefore, in this embodiment, when the first cache unit does not store the latest handwriting style of the first note, the handwriting style of the first historical note is used as the handwriting style of the first note. The handwriting style of the first historical note represents the handwriting style that the user has recently liked, which is more in line with the user's usage habits.

[0061] Please refer to Figure 6 , Figure 6 A flowchart of step S30 of the method for displaying multiple pages of notes provided in this application, according to Embodiment Three. Further, in... Figure 1 Based on the provided display method, in one embodiment of this application, the step of setting the handwriting style of the handwriting style control to the handwriting style of the first note includes: S35. Determine whether there are historical handwritings in the first notebook; S36. If so, obtain the handwriting style of the historical handwriting, the handwriting style of the first note is the handwriting style of the historical handwriting, and then set the handwriting style of the handwriting style control to the handwriting style of the historical handwriting. S37. If not, obtain the handwriting style of the most recently closed first history note, the handwriting style of the first note is the handwriting style of the first history note, and then set the handwriting style of the handwriting style control to the handwriting style of the first history note.

[0062] In other words, this application determines whether historical handwriting exists in the first note. If historical handwriting exists in the first note (meaning the first note is not a newly created note), the handwriting style of the historical handwriting is obtained, and the handwriting style of the first note is the handwriting style of the historical handwriting. Then, the handwriting style of the handwriting style control is set to the handwriting style of the historical handwriting. The handwriting style of the historical handwriting is the handwriting style used in the first note, thus maintaining the continuity and consistency of the handwriting in the first note. If historical handwriting does not exist in the first note (meaning the first note may be a newly created note or a historical note may have been deleted), the handwriting style of the most recently closed first historical note is obtained, and the handwriting style of the first note is the handwriting style of the first historical note. Then, the handwriting style of the handwriting style control is set to the handwriting style of the first historical note. The handwriting style of the first historical note represents the handwriting style that the user has recently preferred, which better matches the user's usage habits.

[0063] Please refer to Figure 7 , Figure 7 A flowchart of step S30 of the method for displaying multiple pages of notes provided in this application, according to Embodiment Four. Further, in Figure 1 Based on the provided display method, in another embodiment of this application, the step of setting the handwriting style of the handwriting style control to the handwriting style of the first note includes: S38. Determine whether there are historical handwritings in the first notebook; S39. If so, obtain the handwriting style of the historical handwriting, the handwriting style of the first note is the handwriting style of the historical handwriting, and then set the handwriting style of the handwriting style control to the handwriting style of the historical handwriting. S3A. If not, obtain the preset handwriting style, the handwriting style of the first note is the preset handwriting style, and then set the handwriting style of the handwriting style control to the preset handwriting style.

[0064] In other words, this application determines whether historical handwriting exists in the first note. If historical handwriting exists in the first note, meaning the first note is not a newly created note, then the handwriting style of the historical handwriting is obtained, and the handwriting style of the first note is the handwriting style of the historical handwriting. Then, the handwriting style of the handwriting style control is set to the handwriting style of the historical handwriting. The handwriting style of the historical handwriting is the handwriting style used in the first note, thus maintaining the continuity and consistency of the handwriting in the first note. If historical handwriting does not exist in the first note, meaning the first note may be a newly created note or a historical note may have been deleted, then a preset handwriting style is obtained, and the handwriting style of the first note is the preset handwriting style. Then, the handwriting style of the handwriting style control is set to the preset handwriting style.

[0065] Please refer to Figure 8 , Figure 8 A flowchart of step S30 of the method for displaying multiple pages of notes provided in this application is shown in Embodiment Five. Further, in...

The step of setting the handwriting style of the handwriting style control to the handwriting style of the first note includes: S3B: Determine whether the latest handwriting style of the first note is stored in the first cache unit; S3C, if so, then obtain the latest handwriting style of the first note from the first cache unit, the handwriting style of the first note is the latest handwriting style of the first note, and then set the handwriting style of the handwriting style control to the latest handwriting style of the first note. S3D, if not, determine whether there is historical handwriting in the first note; S3E, If yes, then obtain the handwriting style of the historical handwriting, the handwriting style of the first note is the handwriting style of the historical handwriting, and then set the handwriting style of the handwriting style control to the handwriting style of the historical handwriting. S3F: If not, obtain the preset handwriting style, the handwriting style of the first note is the preset handwriting style, and then set the handwriting style of the handwriting style control to the preset handwriting style.

[0066] In other words, when the first cache unit stores the latest handwriting style of the first note, the latest handwriting style of the first note is retrieved from the first cache unit, and then the handwriting style of the handwriting style control is set to the latest handwriting style of the first note. By using the first cache unit to store the latest handwriting style of the first note, this application allows users to quickly obtain the handwriting style of the first note when switching between different notes, reducing the computational process and enabling the handwriting style control to be quickly set to the handwriting style of the first note. Therefore, it reduces switching latency and improves the user experience.

[0067] When the first cache unit does not store the latest handwriting style of the first note, it is determined whether there is historical handwriting in the first note. If there is historical handwriting in the first note, the handwriting style of the historical handwriting is obtained, and the handwriting style of the first note is the handwriting style of the historical handwriting. Then, the handwriting style of the handwriting style control is set to the handwriting style of the historical handwriting. The handwriting style of the historical handwriting is the handwriting style used in the first note, thus maintaining the continuity and consistency of the handwriting in the first note. If there is no historical handwriting in the first note, a preset handwriting style is obtained, and the handwriting style of the first note is the preset handwriting style. Then, the handwriting style of the handwriting style control is set to the preset handwriting style.

S3I. If not, determine whether there is any historical handwriting in the first note; S3J, If yes, then obtain the handwriting style of the historical handwriting, the handwriting style of the first note is the handwriting style of the historical handwriting, and then set the handwriting style of the handwriting style control to the handwriting style of the historical handwriting. S3K, if not, then obtain the handwriting style of the most recently closed first history note, the handwriting style of the first note is the handwriting style of the first history note, and then set the handwriting style of the handwriting style control to the handwriting style of the first history note.

[0069] In other words, when the first cache unit stores the latest handwriting style of the first note, the latest handwriting style of the first note is retrieved from the first cache unit, and then the handwriting style of the handwriting style control is set to the latest handwriting style of the first note. By using the first cache unit to store the latest handwriting style of the first note, this application allows users to quickly obtain the handwriting style of the first note when switching between different notes, reducing the computational process and enabling the handwriting style control to be quickly set to the handwriting style of the first note. Therefore, it reduces switching latency and improves the user experience.

[0070] When the first cache unit does not store the latest handwriting style of the first note, it is determined whether there is historical handwriting in the first note. If there is historical handwriting, the handwriting style of the historical handwriting is obtained, and the handwriting style of the first note is the handwriting style of the historical handwriting. Then, the handwriting style of the handwriting style control is set to the handwriting style of the historical handwriting. The handwriting style of the historical handwriting is the handwriting style used in the first note, thus maintaining the continuity and consistency of the handwriting in the first note. If there is no historical handwriting in the first note, that is, the first note may be a newly created note or a historical note has been deleted, the handwriting style of the most recently closed first historical note is obtained, and the handwriting style of the first note is the handwriting style of the first historical note. Then, the handwriting style of the handwriting style control is set to the handwriting style of the first historical note. The handwriting style of the first historical note represents the handwriting style that the user has recently liked, which is more in line with the user's usage habits.
