For example, the microcontroller may include an image processing module, a picture detection module, and the like, where the image processing module may perform a preset image processing operation on the obtained raw image data, for example, one or more of antialiasing, dithering, gray conversion, and contrast enhancement, and obtain image data of a picture to be displayed therefrom, where each pixel in the picture to be displayed has a corresponding color value, where the color value includes a gray scale value. And then the picture detection module analyzes the original image data to obtain a picture analysis result, and the microcontroller obtains a refresh strategy corresponding to the original image data according to the picture analysis result, wherein the picture analysis result at least comprises picture update frequency which is equivalent to a frame rate, and the microcontroller matches a refresh mode corresponding to the current frame rate according to a mapping relation between the frame rate and the refresh mode. For example, when the frame rate is in a preset numerical range, a specific refresh mode, such as A2 refresh mode, DU refresh mode, etc. with a faster refresh rate, GC16 refresh mode, etc. with a slower refresh rate, is matched.
In addition, the screen driving module is connected with the microcontroller, and the screen driving module receives image data of a picture to be displayed and a refresh mode matched with the picture to be displayed, converts the picture to be displayed into driving waveform data according to the received refresh mode, and the time sequence control circuit and the power supply control circuit are used for driving the electronic ink screen to display the picture according to the driving waveform data. Specifically, the screen driving module is connected with the time sequence control circuit, the time sequence control circuit is connected with the electronic ink screen, the power supply control circuit is connected with the time sequence control circuit and the electronic ink screen, the time sequence control circuit is used for providing control signals for controlling the generation and the withdrawal of driving voltage for the power supply control circuit, and the time sequence control circuit is also used for providing driving signals for driving the electronic ink screen for the electronic ink screen according to the refreshing mode of the electronic ink screen so as to enable the electronic ink screen to display a picture to be displayed.
Fig. 1 is a flowchart of a screen clearing display method of an ink screen according to an embodiment of the present application, where the screen clearing display method of the ink screen according to the embodiment of the present application may be executed by a screen clearing display device of the ink screen, and the screen clearing display device of the ink screen may be implemented by hardware and/or software and integrated in a display device on which an electronic ink screen is mounted.
The following description will be made taking, as an example, a screen clearing display method in which a screen clearing display device of an ink screen executes a screen clearing display method of an ink screen.
Referring to fig. 1, the clear screen display method of the ink screen includes:
step S101, judging whether the current display state meets the preset screen clearing display condition.
The processor is used for correspondingly selecting whether to perform the screen cleaning operation after confirming the screen cleaning display conditions. It should be noted that, in the display device, the microcontroller controls the pixel point to reach the expected pixel gray value by sending a driving pulse, the driving pulse includes a signal of change of the voltage difference (driving voltage) between the electrodes on both sides of the ink capsule and the duration of the signal of change (represented by a frame form), and the microcontroller controls the ink capsule according to the driving pulse, so that the pixel gray value is changed. However, in the process of actually controlling the ink screen to display, due to factors such as external resistance, pressure stability, electric field interference and the like, errors occur in actual movement of pigment particles, and the pigment particles cannot accurately move to an expected position, which can bring about the phenomenon of afterimage common to the ink screen. For example, since the ink screen is composed of a plurality of closely arranged ink capsules, there is a problem of electric field crosstalk between adjacent ink capsules, that is, an electric field formed by two electrodes corresponding to one ink capsule design does not completely restrict pigment particles in the one ink capsule, and when pigment particles in one ink capsule move under the action of the electric field, weak electric fields occur in adjacent ink capsules, and unexpected movement of pigment particles occurs. Therefore, when the ink screen displays an image, the range of the actual influence in the ink screen is larger than the expected range corresponding to the image to be displayed according to the display control electric field generated by the image components to be displayed; when the screen needs to be refreshed and the original image component is eliminated, the outline (the part with increased display area) of the eliminated image component is left in the screen, and unexpected afterimages appear.
Thus, the timing for triggering the screen-clearing function can be defined by setting different screen-clearing display conditions, and the following list of possible screen-clearing display conditions: 1. the current screen is in a display state of opening the screen cleaning function, and it is required to be noted that when the screen ghost affects the look and feel of a user, the user can open the screen cleaning function by triggering a control related to the screen cleaning function in the display device; the screen cleaning function may also be turned on by physical manipulation of a physical key connected to the display device, and the present application is not limited herein. When the processor of the display device receives the screen cleaning instruction corresponding to the triggering operation, the ink screen is driven to enter a screen cleaning state. 2. The time length of the interval from the last historical screen cleaning event reaches a preset threshold value, and it is to be noted that, since the display error caused by the screen ghost can be accumulated continuously in the process of refreshing the picture, in order to avoid the accumulation of the display error to directly influence the look and feel of the user, the maximum acceptable display error can be defined by defining the preset threshold value, so that the good look and feel of the user is maintained, and smooth use experience is provided. The processor can set a timer after each screen cleaning action is completed, and can forcedly enter a screen cleaning state when the timer reaches a preset threshold value and reset the timer. By setting the timing self-starting of screen cleaning, the display quality of the picture is effectively controlled without manually triggering screen cleaning. 3. It should be noted that, in the case that the current screen has switched the screen refresh mode, the number of driving frames of the corresponding driving waveform sequence is different in different screen refresh modes, for example, the A2 refresh mode of the ink screen supports display of two colors of black and white, the waveform sequence from black to white or from white to black needs to pass through about 10 driving frames, the GC16 refresh mode of the ink screen supports display of 16 gray scales, and from one gray scale to another gray scale needs to pass through about 30 to 40 driving frames, so that the processor can execute a screen cleaning operation after the screen refresh mode is switched to eliminate screen residues left by the previous screen refresh mode, and better support the new screen refresh mode. 4. The difference between the pixel change ratio of the to-be-displayed picture and the current display picture is larger than the preset ratio threshold, and the clear screen display conditions I, II and III is that, in order to ensure the display effect of each frame of picture, before each picture updating display, the processor compares the to-be-displayed picture with the current display picture to obtain the pixel change ratio, the larger the pixel change ratio is, the larger the area of the possible ghost is, so that the larger the pixel change area is considered to be influenced by the screen ghost by setting the preset ratio threshold and exceeding the preset ratio threshold, and the processor drives the ink screen to clear the screen under the condition that the pixel change ratio is larger than the preset ratio threshold. 5. The historical accumulated times of screen refreshing reaches a preset time threshold, and it is noted that display errors are likely to exist after each picture refreshing, so that the display errors are accumulated continuously after multiple screen refreshing, and after a certain degree, the display pictures are greatly affected, and the reading disorder of a user is caused. Therefore, the processor counts after each screen refreshing, and after the preset times of threshold values are reached, the display errors are considered to be accumulated to the limit, and the processor drives the ink screen to clear and resets the count. It will be appreciated that the above list of several clear display conditions is merely exemplary, and that the user may also set other conditions in conjunction with his reading habits, and the application is not limited thereto. In addition, any screen cleaning display condition is satisfied, the screen cleaning action of the ink screen can be triggered, so that the processor can judge whether the current display state satisfies one of a plurality of preset screen cleaning display conditions, and under the condition that the screen cleaning display condition is satisfied, the screen cleaning action is performed after the display of the current display picture is completed.
Step S102, responding to a judging result meeting a preset screen clearing display condition, acquiring at least one historical waveform sequence from a historical display picture to the current display picture of each pixel point in the current display picture, and confirming a corresponding standard screen clearing sequence according to a screen clearing display mode corresponding to each pixel point.
It should be noted that, first, the screen cleaning operation may be performed on the whole screen or may be performed on a sub-area of the screen, in addition, the screen display of the screen cleaning may be black-before-white, white-before-black, white-alone or black-alone, and in the corresponding screen cleaning display mode, the standard screen cleaning sequence of the pixel points may be further determined according to different gray scale values, so that the processor needs to determine the corresponding standard screen cleaning sequence based on the screen cleaning display mode corresponding to each pixel point.
Optionally, the step of obtaining the standard screen cleaning sequence according to the screen cleaning display mode matching corresponding to each pixel point includes:
confirming a corresponding clear screen display mode according to the position of each pixel point in the update area of the current application window;
and confirming the corresponding standard screen clearing sequence based on the screen clearing display mode of each pixel point.
For example, the processor may perform application identification on the current application window, match a preset configuration file according to the identification result, and further perform sub-region division on the current application window according to the preset configuration file, where the sub-region division may refer to a control type, a control size, a control hierarchy, a control content, and the like, and configure a corresponding refresh mode for each sub-region according to a mapping relationship between a content update frequency and a refresh mode. The clear display modes corresponding to the different refresh modes are different, such as a clear display mode corresponding to the A2 refresh mode, a clear display mode corresponding to the GC16 refresh mode.
In addition, each time the processor drives the pixel point to perform the screen cleaning action, the standard waveform sequence corresponding to the pixel point can be uniformly adopted, but unnecessary energy consumption is caused. Therefore, the processor also acquires at least one historical waveform sequence from the historical display picture to the current display picture, simplifies the standard waveform sequence based on the historical waveform sequence, can effectively reduce the energy consumption of the screen cleaning action, and simultaneously ensures the screen cleaning effect.
And step S103, comparing the historical waveform sequence of each pixel point with a corresponding standard clear screen sequence, and confirming a target repeated sub-sequence corresponding to each pixel point.
It can be understood that each pixel point is driven from the historical display picture to the current display picture based on the historical waveform sequence, at least one group of orderly arranged driving frames are corresponding to the standard screen cleaning sequence for driving the pixel points to clean the screen, and another group of orderly arranged driving frames are corresponding to the standard screen cleaning sequence, because the lengths of the standard screen cleaning sequence and the historical waveform sequence for driving the single image frame are not necessarily consistent, the effect of complete comparison is achieved, the continuous repeated driving frames can be accurately determined by combining the historical waveform sequences of multiple frames, and under the condition of keeping the screen cleaning effect of the standard screen cleaning sequence, only the residual driving frames are executed to finish the screen cleaning, so that the effect of reducing the energy consumption is achieved.
In one embodiment, fig. 2 is a process of a method for confirming a target repetitive sub-sequence corresponding to each pixel, and as shown in fig. 2, a specific process for confirming a target repetitive sub-sequence corresponding to each pixel is provided, which specifically includes the following steps:
step S1031, obtaining a target history sequence according to at least one history waveform sequence corresponding to a history display picture adjacent to the current display picture of each pixel point.
And S1032, comparing the head end sequence of the screen clearing sequence with the tail end sequence of the target history sequence to determine the longest repeated subsequence as the target repeated subsequence.
It should be noted that, since the length of the standard clear sequence is not necessarily consistent with the length of the historical waveform sequence for driving a single image frame, the length of the standard clear sequence needs to be referred to, specifically, when the sum of the lengths of all the historical waveform sequences is greater than or equal to the clear waveform sequence, the historical waveform sequences can be spliced in a time reverse manner in sequence until the length of the spliced waveform sequence is greater than or equal to the length of the clear sequence, the waveform sequence is taken as a target historical sequence, and when the sum of the lengths of all the historical waveform sequences is smaller than the Yu Qingbing waveform sequence, the waveform sequence after the splicing of all the historical waveform sequences is directly taken as a target historical sequence. Of course, when only one history waveform sequence exists or the length of the adjacent history waveform sequence is larger than that of the clear screen waveform sequence, the history waveform sequence is directly used as the target history sequence. The target repeated sub-sequence which is simultaneously positioned at the tail end of the historical waveform sequence and at the head end of the standard clear screen sequence can be obtained through the process. Specifically, the standard screen cleaning sequence corresponding to each pixel point can be segmented into a plurality of subsequences in a frame-by-frame increasing mode from the head end, and each subsequence is compared with the tail end sequence of the corresponding target history sequence to obtain a repeated subsequence; and selecting the record with the largest length from the repeated subsequences as a target repeated subsequence. For example, as shown in fig. 3, if the waveform sequence length of driving a single frame image frame is 7 and the corresponding standard clear sequence length is 14, then, taking the historical waveform sequences corresponding to the first two frames of image frames with pixels adjacent to the current display picture as 1011110 and 1001110 respectively, and the corresponding standard clear sequence is 11101001110111 as an example, since the standard clear sequence is exactly twice the waveform sequence length of driving a single frame image frame, then, the two historical waveform sequences can be spliced into the target historical sequence: 10111101001110. next, we can segment the standard clear sequence from the head end in a frame-by-frame increment into a number of sub-sequences, including 1, 11, 111, 1110, 11101. And comparing the multiple subsequences with the tail end sequences of the corresponding target historical sequences to obtain repeated subsequences 1110 and 11101001110, wherein the target repeated subsequence is the longest in length, namely 11101001110. It will be appreciated that after the comparison is completed, there may be multiple sequences in the set of repeated sub-sequences, or an empty set, and if the set is an empty set, then the target repeated sub-sequence is empty.
And step S104, removing the corresponding target repeated subsequence from the standard screen clearing sequence corresponding to the pixel point to obtain a target screen clearing sequence.
The processor deletes the target repeated sub-sequence and the part of the target repeated sub-sequence from the head end according to the target repeated sub-sequence obtained in step S103 to obtain a remaining waveform sequence, and it can be understood that the target repeated sub-sequence is an executed driving frame, and the remaining waveform sequence is a non-executed driving frame, so that the non-executed driving frame can be used as the target repeated sub-sequence, and as an example, the target repeated sub-sequence 11101001110 in the standard repeated sub-sequence 11101001110111 is deleted on the basis of fig. 3, and the target repeated sub-sequence 111 can be obtained. Therefore, the number of required driving frames can be reduced, and the energy output of the display device can be effectively saved.
Step 105, based on the target screen cleaning sequence, driving the ink screen to clean.
Judging whether the current display state meets the preset screen clearing display condition or not; responding to a judging result meeting a preset screen clearing display condition, acquiring at least one historical waveform sequence of each pixel point in a current display picture from a historical display picture to the current display picture, and confirming a corresponding standard screen clearing sequence according to a screen clearing display mode corresponding to each pixel point; comparing the historical waveform sequence of each pixel point with a corresponding standard clear screen sequence, and confirming a target repeated sub-sequence corresponding to each pixel point; then removing the corresponding target repeated subsequence from the standard clear sequence corresponding to the pixel point to obtain a target clear sequence; and finally, driving the ink screen to clear the screen based on the target screen clearing sequence. The method and the device have the advantages that repeated driving frames are removed by comparing the historical waveform sequence with the screen cleaning waveform sequence, the screen cleaning driving sequence is simplified, unnecessary energy consumption is reduced, and the screen cleaning efficiency is improved.
Further, the color of the screen pixels after the screen is cleaned by the display device may be white or black, for example, if the display device enables the night mode, the color of the screen pixels after the screen is cleaned is black, and if the display device is in the normal mode, the color of the screen pixels after the screen is cleaned is white. For example, in the normal mode, the screen cleaning process is from black to white, and then the current color value is a pixel point close to white, which is equivalent to the display effect after the screen cleaning process is close to the display effect, so that the processor can exclude the pixel point close to white before starting the screen cleaning process, and perform the screen cleaning process on the rest pixel points. For example, a color threshold range of 0xFF- Δa to 0xFF may be set, where Δa is the maximum acceptable pixel difference value, excluding pixels whose color values fall within the color threshold range, e.g., a pale gray that is off-white. For example, in the night mode, the screen cleaning process is from white to black, and the current color value is a pixel point close to black, which is equivalent to the display effect after the screen cleaning process, so that the processor can exclude the pixel point close to black before starting the screen cleaning process, and perform the screen cleaning process on the rest pixel points. For example, a color threshold may be set to a range of 0 to 0+Δb, where Δb is the maximum acceptable pixel difference value, and pixels with color values falling within the color threshold range are excluded, for example, dark gray with black color, where, based on this, optionally, before obtaining at least one historical waveform sequence of each pixel in the current display frame from the historical display frame to the current display frame, and obtaining the standard clear screen sequence according to the clear screen display mode matching corresponding to each pixel, further includes:
And screening out target pixel points meeting preset color conditions from the pixel points of the current display picture.
Accordingly, the subsequent processing procedure can be developed for the obtained target pixel, correspondingly, at least one historical waveform sequence of each pixel in the current display picture from the historical display picture to the current display picture is obtained, and a standard clear screen sequence is obtained according to the clear screen display mode matching corresponding to each pixel, and the method comprises the following steps:
obtaining at least one historical waveform sequence of each target pixel point in the current display picture from the historical display picture to the current display picture, and obtaining a standard screen clearing sequence according to screen clearing display mode matching corresponding to each target pixel point.
Above-mentioned, through getting rid of the pixel point in the color value range of presetted near white or near black, effectively reduce the data volume of clear screen processing, improve clear screen efficiency, reach the visual effect of quick clear screen.
Optionally, in the reading process, if the user obviously observes that the display screen of the ink screen is abnormal, the active triggering of the screen cleaning event may be considered, specifically, before the judging whether the current display state meets the preset screen cleaning display condition, the method further includes:
And receiving physical operation of a screen cleaning control acting on a display interface, or receiving physical operation of a physical key connected with the ink screen.
It should be noted that the physical key may be a key of the display device, or may be provided by a peripheral device connected to the display device, where the connection manner may be a wireless connection such as bluetooth, WIFI, or a wired connection, and the application is not limited in any way. Based on the physical operation, when the processor of the display device receives a corresponding screen cleaning instruction triggered by the physical operation, the processor drives the ink screen to enter a screen cleaning state so as to prepare for next screen refreshing. Through the mode that provides the initiative and trigger clear screen, the user can in time adjust the display effect of picture, ensures the use experience of ink screen.
