[0002] In recent years, with the development of information and electronic technologies, electronic devices have increasingly penetrated from personal entertainment terminals to industries such as education and business. Touchscreen handwriting technology has also been widely used in electronic devices; however, handwriting latency is a key indicator affecting the input experience. Statistics show that in electronic devices supporting touchscreen handwriting technology, the latency from loading handwriting data on the screen to displaying the handwriting is generally around 100ms. Furthermore, as the amount of writing increases, the complexity of the screen increases, and the amount of data processed by the system per frame increases, the latency of handwriting display also increases significantly, resulting in sluggish handwriting display and a poor user experience.

[0003] The process of displaying handwriting on electronic devices specifically includes: acquiring point data, then rendering and drawing the point data to obtain handwriting image data, and finally displaying the handwriting on the electronic device based on the handwriting image data. The rendering and drawing process takes up too much time in the entire handwriting display process, resulting in a slow process from loading the handwriting data on the screen to displaying the handwriting, thus affecting the user experience.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and do not limit the number of objects; for example, a first object can be one or more, and should not be construed as indicating or implying relative importance. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. In addition, unless otherwise expressly specified and limited, the terms "set," "install," "connect," "link," and "serialize" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two elements. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] The handwriting display method provided in this application embodiment can be used in electronic devices, such as tablet computers, mobile phones, e-readers, and personal digital assistants (PDAs) based on displays. Specifically, the electronic device may include a display screen, an image processing module, a microcontroller, a screen driver module, a timing control circuit, and a power control circuit.

[0023] The embodiments of this application will be described in detail below.

[0024] Figure 1 This is a flowchart of a first embodiment of the handwriting display method for a display screen provided in this application. The handwriting display method provided in this application embodiment can be executed by a handwriting display device, which can be implemented by hardware and / or software and integrated into an electronic device.

[0025] The following description uses a handwriting display device as an example to illustrate the method of displaying handwriting. (Reference) Figure 1 The handwritten handwriting display method includes: Step S10: Obtain the reporting data of handwritten strokes.

[0026] In this step, the system acquires point data of the user's handwritten input on the display screen. This point data refers to a series of continuous or discontinuous handwritten points drawn by the user on the screen, including but not limited to coordinate information, time information, handwriting type and width, handwriting pressure information, and handwriting tilt information. The point data can be acquired in real-time via a stylus sensor or by reading the touch point coordinates from the display screen; no specific limitation is imposed here.

[0027] In addition, handwriting pressure and tilt information can be obtained from the stylus. For example, the stylus can detect the pressure at the pen tip and the tilt angle of the pen body, and then feed back the corresponding handwriting pressure and tilt information to the display screen in real time. Alternatively, the display screen can detect the pen tip pressure and tilt angle of the stylus to obtain the handwriting pressure and tilt information. Simultaneously, the display screen determines the reporting coordinates and reporting time based on the handwriting operation, and determines the handwriting input information based on the reporting coordinates and reporting time, handwriting pressure information, and / or handwriting tilt information. The handwriting type and handwriting width are preset in the display screen or set by the user.

[0028] Step S20: Divide the handwritten handwriting point data into at least two groups of point data based on strokes. Each group of point data includes point data corresponding to at least one stroke.

[0029] When a user inputs handwriting, each stroke involves putting down the pen, moving it, and lifting it. Therefore, the display screen can determine whether a stroke is complete using existing technology. Each stroke includes several reporting points. In this embodiment, the reporting points of the handwriting are divided into at least two groups of reporting points, based on the number of strokes. That is, further, before step S20, the number of strokes in the handwriting can be obtained, and it can be determined whether the number of strokes is greater than 1. If so, step S20 is executed; otherwise, the number of strokes is 1, and conventional processing methods are used to render and draw the handwriting.

[0030] Step S30: Assign at least two sets of reporting data to at least two threads, and each thread is assigned at least one set of reporting data.

[0031] In other words, this application uses at least two threads to process the reporting data, and each thread processes at least one set of reporting data.

[0032] Step S40: Use at least two threads to simultaneously render and draw at least two sets of reporting data to obtain handwritten handwriting image data.

[0033] Compared to existing technologies that use a single thread to render and draw the reported data, this application uses at least two threads to render and draw at least two sets of reported data simultaneously to obtain handwritten handwriting image data, thereby improving the speed of handwritten handwriting rendering and drawing, and thus improving the display speed of handwritten handwriting and user experience.

[0034] Step S50: Display the handwritten handwriting on the display screen according to the handwritten handwriting image data.

[0035] Specifically, after rendering and drawing at least two sets of reporting data to obtain handwritten handwriting image data, the driving waveform of the handwritten handwriting is obtained based on the handwritten handwriting image data, and then the driving waveform is used to drive the display screen to display the handwritten handwriting.

[0036] In summary, this application improves the speed of handwriting image data by dividing the handwritten stroke data into at least two groups of stroke data, allocating the at least two groups of stroke data to at least two threads, and then using the at least two threads to simultaneously render and draw the at least two groups of stroke data. This improves the speed of handwriting rendering and drawing, thereby improving the display speed of handwriting and the user experience.

[0037] Please refer to Figure 2 , Figure 2 A flowchart of a second embodiment of the handwriting display method for the display screen provided in this application. Further, in Figure 1 Based on the provided handwriting display method, in one embodiment of this application, before the step of dividing the handwriting point data into at least two groups of point data by stroke, the handwriting display method further includes: Step S60: Obtain the number of reported points in the handwritten handwriting; The step of dividing the handwritten mark data into at least two groups of mark data based on strokes includes: Step S21: Divide the handwritten stroke data into at least two groups of stroke data, so that the difference between the number of strokes in each group of stroke data is minimized.

[0038] In the process of using at least two threads to render and draw the reported data to obtain handwritten handwriting image data, the handwritten handwriting image data is obtained after one thread finishes rendering and drawing. This handwritten handwriting image data is then sent to a cache unit. Next, the display screen uses the handwritten handwriting image data from the cache unit to obtain the driving waveform of the handwritten handwriting. Finally, the driving waveform drives the display screen to display the handwritten handwriting. As can be seen, the rendering and drawing processes of multiple threads are performed simultaneously. The handwritten handwriting image data corresponding to the slowest rendering and drawing process will be displayed the slowest. Therefore, to improve the speed of complete display, this application obtains the number of reported points of the handwritten handwriting and then divides the reported point data into at least two groups of reported point data based on strokes. This minimizes the difference in the number of reported points between each two groups, thus minimizing the difference in rendering and drawing time among multiple threads, thereby enabling the complete handwritten handwriting to be displayed in the shortest possible time.

[0039] Please refer to Figure 3 , Figure 3 A flowchart of Embodiment 3 of the handwritten handwriting display method for the display screen provided in this application. Figure 2 Based on the provided handwriting display method, further in one embodiment of this application, the step of obtaining the number of dots in the handwriting includes: Step S61: Weight the reported points data according to the parameter information of the handwritten handwriting to obtain the number of reported points of the handwritten handwriting.

[0040] The parameter information includes handwriting type and handwriting width. Different handwriting types and widths correspond to different numbers of reporting points. Handwriting types include fountain pen, pencil, ballpoint pen, brush pen, marker, etc., and each handwriting type has a different weighting coefficient for reporting points. Furthermore, handwriting width can be between 0.1 and 1.0 mm; different handwriting widths result in different weighting coefficients for reporting points in a single handwritten stroke. Therefore, in this embodiment, the number of reporting points can be obtained by weighting the reporting data according to the handwriting type, or by weighting the reporting data according to the handwriting width, or by weighting the reporting data according to both the handwriting type and width. Because different handwriting types and widths result in different numbers of reporting points in each group of reporting data, the rendering processing time also varies. Therefore, this application obtains the number of reported points by weighting the reported point count, which can adapt to different handwriting types and handwriting widths, so that the difference between the reported point counts of each two sets of reported point data is minimized, and the difference in rendering and drawing processing time of multiple threads is minimized, thereby enabling the display of complete handwriting in the shortest possible time.

[0041] exist Figure 1 Based on the provided handwriting display method, in one embodiment of this application, the handwriting includes at least two handwriting graphics, and the handwriting graphics include at least one stroke. When the handwriting time interval between two adjacent strokes exceeds a preset time, the strokes of the two adjacent strokes belong to the strokes of different handwriting graphics. Among them, the reporting data corresponding to one of the handwritten graphics is a set of reporting data.

[0042] In one embodiment of this application, a complete handwritten graphic can be determined according to the handwriting time interval between two adjacent strokes. When the handwriting time interval between two adjacent strokes exceeds a preset duration, the two adjacent strokes belong to different handwritten graphics. Furthermore, the shortest distance between two handwritten graphics is greater than a first preset distance, where the first preset distance is a pre-set distance.

[0043] In this embodiment, by setting a set of reporting data corresponding to a handwritten graphic, at least two threads are used to render and draw the reporting data. Moreover, one thread renders and draws the reporting data corresponding to a handwritten graphic to obtain handwritten handwriting image data. This improves the rendering and drawing speed while enabling multiple handwritten graphics to be displayed and updated simultaneously, which is beneficial to improving the user experience.

[0044] The handwritten graphic may include a combination of one or more of the following: irregular graphics, text, symbols, numbers, polygons, and circles.

[0045] Please refer to Figure 4 , Figure 4 A flowchart of step S21 of the handwritten handwriting display method for the display screen provided in this application. Figure 2 Based on the provided handwriting display method, further in one embodiment of this application, the step of dividing the handwriting point data into at least two groups of point data by stroke, such that the difference between the number of points in each two groups of point data is minimized, includes: Step S211: Obtain the number n of handwritten graphics contained in the handwritten handwriting, where n is a positive integer, and the handwritten graphics include at least one stroke; Step S212: Determine whether n is greater than 1. If so, divide the handwritten stroke data into m groups of data based on the handwritten shape, where m is greater than or equal to 2, so that the difference between the number of points reported in each two groups of data is minimized. Otherwise, divide the handwritten stroke data into at least two groups of data based on the stroke, so that the difference between the number of points reported in each two groups of data is minimized.

[0046] This application obtains the number n of handwritten shapes contained in the handwritten handwriting, and then determines the grouping of the reporting data based on whether n is greater than 1. Specifically, when n is greater than 1, the reporting data of the handwritten handwriting is divided into m groups of reporting data, with m greater than or equal to 2. n and m can be the same or different, mainly to minimize the difference in the number of reporting points between any two groups. For example, if the number of handwritten shapes is 5, the reporting data of the handwritten handwriting is divided into 3 groups of reporting data, with the reporting data of the first to fifth handwritten shapes being 2, 4, 5, 6, and 8 respectively. To minimize the difference in the number of reporting points between any two groups, the first and fourth handwritten shapes are grouped together, the second and third handwritten shapes are grouped together, and the fifth handwritten shape is grouped together.

[0047] When n is not greater than 1, and n is 1, the handwritten point data is divided into at least two groups of point data based on strokes, while minimizing the difference in the number of points reported between any two groups. For example, if the number of handwritten shapes is 1 and the number of strokes in the handwritten shape is 5, the handwritten point data is divided into 3 groups of point data based on strokes, where the point data for the first to fifth strokes are 2, 4, 5, 6, and 8 respectively. To minimize the difference in the number of points reported between any two groups, the first and fourth strokes are grouped together, the second and third strokes are grouped together, and the fifth stroke is grouped together.

[0048] When the handwritten strokes contain multiple handwritten shapes, this application divides the point reporting data of the handwritten strokes into m groups of point reporting data, where m is greater than or equal to 2, based on the handwritten shape. This minimizes the difference in the number of points reported between any two groups, allowing multiple handwritten shapes to be displayed and updated simultaneously, and also minimizing the rendering time, thus improving the display speed and user experience of the handwritten strokes. When the handwritten strokes contain only one handwritten shape, this application divides the point reporting data of the handwritten strokes into at least two groups of point reporting data, based on the stroke. This also minimizes the difference in the number of points reported between any two groups, allowing multiple strokes to be displayed and updated simultaneously, and also minimizing the rendering time, thus improving the display speed and user experience of the handwritten strokes.

[0049] exist Figure 4 Based on the provided handwriting display method, further in one embodiment of this application, the step of obtaining the number n of handwritten graphics contained in the handwriting includes: The number n of handwritten graphics contained in the handwritten handwriting is obtained by recognizing the point data of the handwritten handwriting using OCR technology.

[0050] Optical Character Recognition (OCR) is a technology that uses computers to automatically recognize and interpret text information in images. It can convert text information on paper documents, pictures, photographs, and other media into computer-editable and processable text data. The working principle of OCR technology mainly includes image preprocessing, text segmentation, feature extraction, and character recognition. First, the system preprocesses the input image, including denoising and binarization, to improve the accuracy of subsequent recognition. Then, text segmentation technology extracts the text regions in the image and divides them into individual characters. Next, the system extracts the features of each character and compares them with a pre-trained character library to ultimately recognize the content of each character.

[0051] This application uses OCR technology to identify the number n of handwritten shapes contained in the handwritten handwriting by recognizing the reported point data of the handwritten handwriting. That is, in this embodiment, during the handwritten handwriting input process, OCR technology can recognize a complete handwritten shape when it is input, so the handwritten shapes can be recognized one by one according to the reported point data.

[0052] exist Figure 4 Based on the provided handwriting display method, further, in one embodiment of this application, the step of obtaining the number n of handwritten graphics contained in the handwriting includes: The number n of handwritten graphics contained in the handwritten handwriting is obtained by recognizing the input area of ​​the handwritten handwriting using OCR technology.

[0053] That is, in this embodiment, after the handwritten handwriting is input, the input area of ​​the handwritten handwriting is identified by OCR technology to obtain the number n of handwritten graphics contained in the handwritten handwriting.

[0054] Please refer to Figure 5 , Figure 5 A flowchart of a first embodiment of the handwriting display method for the display screen provided in this application, specifically step S211. Figure 4 Based on the provided handwriting display method, further, in one embodiment of this application, the step of obtaining the number n of handwritten graphics contained in the handwriting includes: Step S2111: Obtain the strokes of the handwritten handwriting, wherein the number of strokes is greater than 1; Step S2112: Arrange the strokes in chronological order and obtain the shortest handwriting spacing between two adjacent strokes; Step S2113: Compare the shortest handwriting spacing with a preset distance to obtain the number n of handwritten shapes contained in the handwriting. When the shortest handwriting spacing is greater than the preset distance, the two adjacent strokes corresponding to the shortest handwriting spacing do not belong to the same handwritten shape.

[0055] In other words, this application obtains the shortest handwriting spacing between two adjacent strokes and compares this shortest handwriting spacing with a preset distance. If the shortest handwriting spacing is greater than the preset distance, the two adjacent strokes are identified as belonging to two different handwritten shapes; if the shortest handwriting spacing is not greater than the preset distance, the two adjacent strokes are identified as belonging to the same handwritten shape, thereby obtaining the number n of handwritten shapes contained in the handwriting. The preset distance is pre-set by the display screen, but can also be set by the user according to actual needs.

[0056] Please refer to Figure 6 , Figure 6 A flowchart of a second embodiment of the handwriting display method for the display screen provided in this application, specifically step S211. Figure 4 Based on the provided handwriting display method, further, in one embodiment of this application, the step of obtaining the number n of handwritten graphics contained in the handwriting includes: Step S2114: Obtain the strokes of the handwritten handwriting, wherein the number of strokes is greater than 1; Step S2115: Arrange the strokes in chronological order and obtain the handwriting time interval between two adjacent strokes; Step S2116: Compare the handwriting time interval with the preset duration to obtain the number n of handwritten graphics contained in the handwriting. When the handwriting time interval is greater than the preset duration, the two adjacent strokes corresponding to the handwriting time interval do not belong to the same handwritten graphic.

[0057] In other words, this application obtains the handwriting time interval between two adjacent strokes and compares the handwriting time interval with a preset duration. If the handwriting time interval is greater than the preset duration, the two adjacent strokes are identified as strokes belonging to two different handwritten shapes; if the handwriting time interval is not greater than the preset duration, the two adjacent strokes are identified as strokes belonging to the same handwritten shape, thereby obtaining the number n of handwritten shapes contained in the handwriting. The preset duration is pre-set by the display screen, but can also be set by the user according to actual needs.

(Reference) Figure 7 A handwriting display device for a display screen, the handwriting display device comprising: an acquisition module 10, a coordinate module 20, a thread module 30, a rendering module 40, and a display module 50.

[0059] The acquisition module 10 is used to acquire the reporting data of handwritten handwriting. The coordinate module 20 is used to divide the handwritten handwriting point data into at least two groups of point data in terms of strokes, and each group of point data includes point data corresponding to at least one stroke. The thread module 30 is used to allocate at least two sets of reporting data to at least two threads, and each thread is allocated at least one set of reporting data; The rendering module 40 is used to simultaneously render and draw at least two sets of reporting data using at least two threads to obtain handwritten handwriting image data. The display module 50 is used to display the handwritten handwriting on the display screen according to the handwritten handwriting image data.

[0060] In summary, this application improves the speed of handwriting image data by dividing the handwritten stroke data into at least two groups of stroke data, allocating the at least two groups of stroke data to at least two threads, and then using the at least two threads to simultaneously render and draw the at least two groups of stroke data. This improves the speed of handwriting rendering and drawing, thereby improving the display speed of handwriting and the user experience.
