Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display method, device, electronic device and storage medium for an ink screen. Background Art

[0002] E-ink display technology dates back to 1996, based on research conducted by the MIT Media Lab. Using electrophoretic particle devices (EPD), these displays closely resemble traditional paper, earning them the nickname "electronic paper." Electronic ink, similar to printing ink, is made of pigments, which explains the similarities between the display and traditional paper. E-ink is typically formulated as a thin film composed of numerous microcapsules, each about the diameter of a human hair. The black and white spheres within these microcapsules are pigment particles with different charges. Initially, the pigment particles are suspended within the microcapsules. When an electric field is applied in a specific direction, the corresponding pigment particles are pushed to the top of the microcapsules, causing the microcapsules to display different colors. These microcapsules, each with a different color, form various text and patterns.

[0003] Compared to the LCD screens of general electronic devices, the display frame rate of the electronic ink screen is much slower. For example, the display frame rate of a mobile phone or tablet screen can be 60 frames / s, which means that it takes 16.7ms to display one image frame, while the display frame rate of the electronic ink screen can be 1.8 frames / s, which means that it takes 550ms to display one image frame. Therefore, when electronic devices with ink screens display images quickly, such as playing animated images, playing videos, updating page content at a high frequency, and scrolling pages, it will cause serious delays in the display of the screen, and even the loss of screen content. In particular, when moving the cursor at a faster speed, the cursor will be displayed delayed on the ink screen. When the cursor movement speed exceeds a certain threshold, the cursor display on the ink screen will be severely delayed or even unable to display normally. The cursor display can only keep up with the cursor position update speed after the cursor stops or the cursor movement speed decreases, resulting in poor display effect. Summary of the Invention

[0024] The display method provided in the embodiments of the present application can be used on an ink screen, especially on an electronic device equipped with an ink screen. The electronic device can be an electronic device based on an ink screen, such as a tablet computer, a mobile phone, an e-reader, a personal digital assistant (PDA), etc. Specifically, the electronic device may include an ink screen, a communication module, a digital signal processor, an image processing module, a microcontroller, a screen driver module, a timing control circuit, and a power control circuit.

[0025] The following is a detailed description of the various embodiments of the present application.

[0026] Figure 1 This is a flowchart of the ink screen display method provided in the present application. The ink screen display method provided in the embodiment of the present application can be executed by a display device, which can be implemented by hardware and / or software and integrated into the ink screen.

[0027] The following description is made by taking the method of displaying an ink screen on a display device as an example. Figure 1 , a method for displaying an ink screen, the method comprising: Step S10: Compare the current display image and the image to be displayed to obtain changed pixels in the image to be displayed, where the changed pixels are pixels that are displayed on the same pixel point of the image to be displayed and the current display image and have different color values.

[0028] The image information of the ink screen display is actually an array composed of multiple pixels. The way to compare the current display screen and the screen to be displayed is to compare the image information of the screen to be displayed with the image information of the current display screen one by one. Specifically, in the embodiment of the present application, the color values ​​of the screen to be displayed and the current display screen at the same pixel point of the ink screen are compared one by one. The color value of the pixel in the screen to be displayed may correspond to the same color value of the pixel in the current display screen, or may correspond to a different color value of the pixel in the current display screen. In the present application, the changed pixel is a pixel with different color values ​​displayed on the same pixel point of the ink screen as the screen to be displayed and the current display screen.

[0029] Step S20: Determine whether the area corresponding to the changed pixels includes a cursor feature area.

[0030] Specifically, the area corresponding to the changed pixel may include only one area, or may include multiple areas, and then determine whether the above area includes the cursor feature area. Because there are many types of cursors, each type of cursor corresponds to a cursor feature area. In this embodiment, if the area corresponding to the changed pixel includes the cursor feature area of ​​any type of cursor, then it is determined that the area corresponding to the changed pixel includes the cursor feature area; otherwise, the area corresponding to the changed pixel does not include the cursor feature area. In another embodiment of the present application, it is also possible to only target a certain type of cursor. If the area corresponding to the changed pixel includes the cursor feature area of ​​a certain type of cursor, then it is determined that the area corresponding to the changed pixel includes the cursor feature area; otherwise, the area corresponding to the changed pixel does not include the cursor feature area.

[0031] Step S30: If the area corresponding to the changed pixel includes a cursor feature area, a cursor pixel set of the cursor feature area is obtained from the changed pixel. When refreshing the current display screen, the ink screen is driven to refresh and display the cursor pixel set according to the first refresh mode.

[0032] That is, when the area corresponding to the changing pixel includes the cursor feature area, the cursor pixel set of the cursor feature area is obtained from the changing pixel, and when refreshing the current display screen, the ink screen is driven to refresh and display the cursor pixel set according to the first refresh mode. When the area corresponding to the changing pixel does not include the cursor feature area, the current display screen and the screen to be displayed are refreshed and displayed in sequence according to the existing refresh method. Therefore, when the area corresponding to the changing pixel includes the cursor feature area, the present application refreshes the cursor feature area of ​​the screen to be displayed in advance within the refresh cycle of the current display screen, thereby avoiding the situation where the cursor display is delayed due to the cursor moving too fast, thereby improving the display effect and user experience of the ink screen.

[0033] Furthermore, in one embodiment of the present application, the first refresh mode and the current refresh mode of the currently displayed screen are different refresh modes, and the refresh time of one frame of the first refresh mode is less than the refresh time of one frame of the current refresh mode of the currently displayed screen. Since the refresh time of one frame of the first refresh mode is shorter, the cursor feature area can be displayed faster, further improving the display speed of the cursor. Among them, as the priority mode of the present application, the first refresh mode is the A2 refresh mode, and the current refresh mode is a refresh mode other than the A2 refresh mode. However, it is easy to imagine that the first refresh mode can also be other existing refresh modes.

[0034] In addition, in another embodiment of the present application, the first refresh mode and the current refresh mode of the currently displayed image are the same refresh mode. For example, the first refresh mode and the current refresh mode of the currently displayed image are both A2 refresh mode or other existing refresh modes.

[0035] Please refer to Figure 2 , Figure 2 This is a flow chart of the embodiment 1 of step S30 of the ink screen display method provided by this application. Figure 1 Based on the provided display method, in one embodiment of the present application, when refreshing the current display screen, the step of driving the ink screen to refresh and display the cursor pixel set according to the first refresh mode includes: Step S31, obtaining a first driving waveform of the cursor pixel set according to a first refresh mode; Step S32: determining whether the pixels refreshed and displayed on the current display screen coincide with the cursor pixel set; Step S33: If no, when refreshing the current display screen, using the first driving waveform to drive the ink screen to refresh and display the cursor pixel set; Step S34: If yes, obtain the overlapping pixel area in the current display screen that overlaps with the cursor pixel set, interrupt the execution of the driving waveform of the overlapping pixel area of ​​the current display screen, and when refreshing the current display screen, use the first driving waveform to drive the ink screen to refresh and display the cursor pixel set.

[0036] Since the e-ink display can refresh pixels concurrently, when the pixels refreshed on the current display do not overlap with the cursor pixel set, the cursor pixel set and the current display can be refreshed and displayed simultaneously. Specifically, when refreshing the current display, the first driving waveform is used to drive the e-ink display to refresh and display the cursor pixel set.

[0037] When the pixels being refreshed on the current display coincide with the cursor pixel set, to ensure that the cursor pixel set is displayed in advance without delay, the overlapping pixel region in the current display that overlaps with the cursor pixel set is obtained, and the driving waveform for the overlapping pixel region of the current display is interrupted. Then, when refreshing the current display, the first driving waveform is used to drive the e-ink display to refresh and display the cursor pixel set. At this point, all other regions of the current display, except the overlapping pixel region, are refreshed and displayed normally.

[0038] To summarize, the present application compares whether the pixels refreshed and displayed on the current display screen overlap with the cursor pixel set. When the pixels refreshed and displayed on the current display screen overlap with the cursor pixel set, the driving waveform of the overlapping pixel area of ​​the current display screen is interrupted, thereby ensuring that the cursor pixel set can be displayed when the current display screen is refreshed.

[0039] Further, in Figure 1 Based on the provided display method, in one embodiment of the present application, when refreshing the current display screen, the step of using the first driving waveform to drive the ink screen to refresh and display the cursor pixel set includes: Step S35: When refreshing the current display screen, obtain the current cursor area pixels in the current display screen, interrupt the execution of the driving waveform of the current cursor area pixels in the current display screen, and use the first driving waveform to drive the ink screen to refresh and display the cursor pixel set.

[0040] Since the current cursor area pixels of the current display screen will be displayed simultaneously when refreshing the current display screen, in order to avoid two cursors appearing on the display screen, in an embodiment of the present application, when refreshing the current display screen, the current cursor area pixels in the current display screen are obtained, and then the driving waveform of the current cursor area pixels of the current display screen is interrupted, and then the first driving waveform is used to drive the ink screen to refresh and display the cursor pixel set.

[0041] Please refer to Figure 3 , Figure 3 This is a flow chart of the second embodiment of the ink screen display method of step S30 provided in this application. Figure 1 Based on the provided display method, in one embodiment of the present application, a cursor pixel set of the cursor feature area is obtained from the changed pixels, and when refreshing the current display screen, the step of driving the ink screen to refresh and display the cursor pixel set according to the first refresh mode includes: Step S36: obtaining the moving speed of the cursor; Step S37: determining whether the moving speed is greater than a preset speed; Step S38: If yes, obtain the cursor pixel set of the cursor feature area from the changed pixels, and when refreshing the current display screen, drive the ink screen to refresh and display the cursor pixel set according to the first refresh mode.

[0042] On an electronic device with an ink screen, when the cursor is moved at a faster speed, the cursor will be displayed delayed on the ink screen. When the cursor movement speed is greater than a certain speed, the cursor display on the ink screen will be severely delayed or may not be displayed normally. The cursor display can only keep up with the cursor position update speed after the cursor stops or the cursor movement speed is reduced. Therefore, in one embodiment of the present application, the technical solution of the present application is adopted only when the movement speed is greater than the preset speed, that is, when refreshing the current display screen, the ink screen is driven to refresh and display the cursor pixel set according to the first refresh mode. When the movement speed moves at a lower speed or the movement speed is less than or equal to the preset speed, it means that the cursor moves slowly. At this time, the cursor can be displayed normally on the ink screen or there may be some display delays, but the display effect can be achieved and meet user needs. At this time, there is no need to refresh the cursor pixel set in advance.

[0043] Please refer to Figure 4 , Figure 4 This is a flowchart of step S36 of the ink screen display method provided by this application. Figure 3Based on the provided display method, in one embodiment of the present application, the step of obtaining the movement speed of the cursor includes: Step S361: Acquire first coordinate information of the cursor on the current display screen and second coordinate information of the cursor on the screen to be displayed; Step S362: Obtain the movement displacement of the cursor according to the first coordinate information and the second coordinate information; Step S363: obtaining a first time when the data of the currently displayed image is updated and a second time when the data of the to-be-displayed image is updated; Step S364: obtaining the time difference between the first time and the second time; Step S365: Obtain the moving speed of the cursor according to the moving displacement and the time difference.

[0044] Among them, obtaining the first coordinate information of the cursor on the currently displayed screen is to obtain the first coordinate information of the current cursor area in the currently displayed screen. Obtaining the second coordinate information of the cursor on the screen to be displayed is to obtain the second coordinate information of the cursor pixel set on the screen to be displayed. Then, the movement displacement of the cursor is obtained based on the first coordinate information and the second coordinate information, and then the first time of data update of the currently displayed screen and the second time of data update of the screen to be displayed are obtained, wherein the first time is also the time when the cursor is at the corresponding position of the currently displayed screen, and the second time is also the time when the cursor is at the corresponding position of the screen to be displayed. Finally, the time difference between the first time and the second time is obtained, and then the movement speed of the cursor can be obtained based on the movement displacement and the time difference, that is, the movement speed is obtained by dividing the movement displacement by the time difference.

[0045] Please refer to Figure 5 , Figure 5 This is a flowchart of step S20 of the ink screen display method provided by this application. Figure 1 Based on the provided display method, in one embodiment of the present application, the step of determining whether the area corresponding to the changed pixel includes a cursor feature area includes: Step S21, dividing the changed pixels into at least one changed region; Step S22: matching the features of the changed area with the preset features of the cursor; Step S23: When the feature matching satisfies a preset condition, the changed region is the cursor feature region, and it is determined that the region corresponding to the changed pixels includes the cursor feature region; Step S24: When the feature matching does not meet the preset conditions, the changed area is not the cursor feature area, and it is determined that the area corresponding to the changed pixels does not include the cursor feature area.

[0046] The changed pixels are segmented into at least one changed region. In one embodiment of the present application, the segmentation of the changed pixels into at least one changed region can be performed using a minimum bounding rectangle algorithm or a clustering algorithm. It is readily apparent that other algorithms can also be used to segment the changed pixels into at least one changed region. The features of the changed region are then matched against preset cursor features. When the feature match satisfies a preset condition, the changed region is considered the cursor feature region, and the region corresponding to the changed pixels is determined to include the cursor feature region. The preset cursor feature can be one or multiple, as there are many types of cursors, each corresponding to a preset cursor feature. When there is one preset cursor feature, the features of the changed region are matched against the preset cursor feature. If the feature match satisfies a preset condition, the changed region is considered the cursor feature region, and the region corresponding to the changed pixels is determined to include the cursor feature region. When there are multiple preset cursor features, the features of the changed region are matched against the multiple preset cursor features. If the feature match with any one of the preset cursor features satisfies a preset condition, the changed region is considered the cursor feature region, and the region corresponding to the changed pixels is determined to include the cursor feature region. The preset condition can be set based on actual circumstances.

[0047] On the contrary, when the feature matching does not meet the preset conditions, the changed area is not the cursor feature area, and it is determined that the area corresponding to the changed pixels does not include the cursor feature area.

[0048] Further, in Figure 5 On the basis of the provided display method, in one embodiment of the present application, the feature of the changing area is the shape outline of the changing area, and the preset feature of the cursor is the shape outline of the cursor. When the similarity between the shape outline of the changing area and the shape outline of the cursor is greater than or equal to 90%, the changing area is the cursor feature area, and it is determined that the area corresponding to the changing pixel includes the cursor feature area; when the similarity between the shape outline of the changing area and the shape outline of the cursor is less than 90%, the changing area is not the cursor feature area, and it is determined that the area corresponding to the changing pixel does not include the cursor feature area. As can be seen from the above, in this embodiment, the preset condition is that the similarity between the shape outline of the changing area and the shape outline of the cursor is greater than or equal to 90%.

[0049] Further, in Figure 5On the basis of the provided display method, in one embodiment of the present application, the characteristic of the changing region is the area of ​​the changing region, and the preset characteristic of the cursor is the cursor area. When the ratio of the area of ​​the changing region to the cursor area is greater than or equal to ninety percent and less than or equal to one hundred percent, the changing region is the cursor characteristic region, and it is determined that the region corresponding to the changing pixel includes the cursor characteristic region; when the ratio of the area of ​​the changing region to the cursor area is less than ninety percent or greater than one hundred percent, the changing region is not the cursor characteristic region, and it is determined that the region corresponding to the changing pixel does not include the cursor characteristic region. As can be seen from the above, in this embodiment, the preset condition is that the ratio of the area of ​​the changing region to the cursor area is greater than or equal to ninety percent and less than or equal to one hundred percent.

[0050] Further, please refer to Figure 6 , Figure 6 This is a flow chart of step S30 of the third embodiment of the ink screen display method provided by this application. Figure 1 Based on the provided display method, in one embodiment of the present application, the step of obtaining a cursor pixel set of the cursor feature area from the changed pixels, and driving the ink screen to refresh and display the cursor pixel set according to a first refresh mode when refreshing the current display screen includes: Step S3A, obtaining the movement displacement of the cursor between the to-be-displayed image and the currently displayed image; Step S3B, determining whether the movement displacement is greater than a first threshold and less than a second threshold; Step S3C: If yes, obtain the cursor pixel set of the cursor feature area from the changed pixels, and when refreshing the current display screen, drive the ink screen to refresh and display the cursor pixel set according to the first refresh mode.

[0051] Since the cursor moves relatively large between the screen to be displayed and the currently displayed screen when the cursor moves quickly, in order to more accurately identify the movement status of the cursor, in an embodiment of the present application, the movement displacement of the cursor between the screen to be displayed and the currently displayed screen is limited to be greater than a first threshold and less than a second threshold. Because when the movement displacement is less than or equal to the first threshold, it means that the cursor moves slowly. At this time, the cursor can be displayed normally on the ink screen or some display delay may occur, but the display effect can be achieved and user needs can be met. At this time, there is no need to refresh the cursor pixel set in advance.

[0052] When the moving displacement is greater than the first threshold and less than the second threshold, it means that the cursor moves faster, and the cursor may be displayed with severe delay or even cannot be displayed normally on the ink screen. The cursor pixel set of the cursor feature area is obtained from the changed pixels. When refreshing the current display screen, the ink screen is driven to refresh and display the cursor pixel set according to the first refresh mode, thereby avoiding the situation where the cursor display delay is caused by the cursor moving too fast, thereby improving the display effect and user experience of the ink screen.

[0053] Furthermore, in an embodiment of the present application, the first threshold is a width value of 10 pixels, and the second threshold is a width value of 50 pixels. It is easy to imagine that the specific values ​​of the first threshold and the second threshold can be flexibly set according to actual conditions.

[0054] The movement displacement of the cursor between the image to be displayed and the currently displayed image can be obtained in the following manner: first coordinate information of the cursor on the currently displayed image is obtained, that is, the first coordinate information of the current cursor area in the currently displayed image is obtained. Second coordinate information of the cursor on the image to be displayed is obtained, that is, the second coordinate information of the cursor pixel set on the image to be displayed is obtained. The movement displacement of the cursor is then obtained based on the first coordinate information and the second coordinate information.

[0055] Figure 7 This is a schematic diagram of the structure of the ink screen display device provided by this application. Figure 7 The display device includes: a first comparison module 10, a judgment module 20 and a driving module 30.

[0056] The comparison module 10 is used to compare the current display image with the image to be displayed, and obtain changed pixels in the image to be displayed, wherein the changed pixels are pixels of the image to be displayed and the current display image displayed on the same pixel point on the ink screen and having different color values; The judging module 20 is used to judge whether the area corresponding to the changed pixel includes a cursor feature area; If the area corresponding to the changed pixel includes a cursor feature area, the driving module 30 obtains a cursor pixel set of the cursor feature area from the changed pixel, and when refreshing the current display screen, drives the ink screen to refresh and display the cursor pixel set according to the first refresh mode.

[0057] That is, when the area corresponding to the changing pixel includes the cursor feature area, the cursor pixel set of the cursor feature area is obtained from the changing pixel, and when refreshing the current display screen, the ink screen is driven to refresh and display the cursor pixel set according to the first refresh mode.
