Fig. 1 is a flowchart of an embodiment of a display control method of an ink screen according to the present application, where the display control method of the ink screen according to the embodiment of the present application may be executed by a display control device of the ink screen, and the display control 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 display control method of an ink panel performed by a display control device of the ink panel. Referring to fig. 1, the display control method of the ink screen includes:

step S10, recording history display data.

The history display data provided in this embodiment includes: historical waveform data and historical color data of pixel points on the ink screen under the driving of the historical waveform data. The historical waveform data comprises a waveform sequence which is driven to display the ink screen and a waveform sequence which is driven to display the ink screen, and the historical color data comprises historical actual color values of pixel points on the ink screen under the driving of the corresponding historical waveform sequence.

In addition, the historical waveform data may be processed by a processor of the display device based on the received raw image data. The display processing procedure of the ink screen will be described taking a display device equipped with a microcontroller, a screen driving module, a timing control circuit, and a power control circuit as an example. Specifically, 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, where each pixel point 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 the 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, the screen driving module receives image data of a picture to be displayed and a refresh mode matched with the picture to be displayed, the picture to be displayed is converted into driving waveform data according to the received refresh mode, the driving waveform data is recorded and stored to be history waveform data, 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.

It should be noted that, when the first display screen is interrupted by the interrupt event, since the driving waveform sequence of the first display screen is not completely applied to the electronic ink screen, the portion of the driving waveform sequence of the first display screen, which is applied to the electronic ink screen, is the applied driving waveform sequence, and the portion of the driving waveform sequence of the first display screen, which is not applied to the electronic ink screen, is the non-applied driving waveform sequence, so that at this time, there is a difference between the target color value of the pixel point of the first display screen and the actual color value of the pixel point of the first display screen. Because the working principle and the working mode of the electronic ink screen are that when the electronic ink screen displays the second display picture, the second display picture is positioned behind the first display picture and is adjacent to the first display picture, the electronic ink screen can determine one or more driving frames from each pixel point of the ink screen to the target color value of the second display picture according to the target color value of the first display picture and the target color value of the second display picture, and determine a driving waveform sequence corresponding to each pixel point based on the driving frames, but at the moment, the target color value of the pixel point of the first display picture and the actual color value of the pixel point of the first display picture have a difference value, so that the driving waveform sequence is used for driving the ink screen to enable the pixel point on the ink screen to display the target color value of the second display picture, thereby leading the ink screen to generate residual images and affecting the display effect.

The historical color data includes a historical actual color value of a pixel on the ink screen driven by the corresponding historical waveform sequence, for example, when the first display screen is interrupted by the interrupt event, since the driving waveform sequence of the first display screen is not completely applied to the electronic ink screen, a portion of the driving waveform sequence of the first display screen that is already applied to the electronic ink screen is the applied driving waveform sequence, a portion of the driving waveform sequence of the first display screen that is not already applied to the electronic ink screen is the non-applied driving waveform sequence, and the historical actual color value is a color value of the pixel on the ink screen driven by the applied driving waveform sequence, but is not a color value of the pixel on the ink screen when the driving waveform sequence of the first display screen is completely applied to the electronic ink screen; when the first display screen is not interrupted by the interrupt event, the historical actual color value is the color value of the pixel point on the ink screen when the driving waveform sequence of the first display screen is completely applied to the electronic ink screen.

Referring to fig. 2, fig. 2 is a schematic diagram of a driving waveform sequence of a first display frame interrupted by an interruption event, and it is assumed that the driving waveform sequence of the first display frame includes 11 total driving frames V1 to V11, and the driving waveform sequence of the first display frame is interrupted by the interruption event in a sixth frame, and when the driving waveform sequence applied includes 6 total driving frames V1 to V6, and when the driving waveform sequence not applied includes 5 total driving frames V7 to V11.

Step S20, detecting and recording an interrupt event.

When an interrupt event occurs, the application detects the interrupt event and records the interrupt event.

And step S30, judging whether the interrupt event is ended, and executing the next step if the interrupt event is ended. If not, continuing to wait for the ending of the interrupt event until the ending signal of the interrupt event is obtained, and executing the next step.

It should be noted that, specific ways for determining whether the interrupt event is ended include: and when the ending signal of the interrupt event is obtained, judging that the interrupt event is ended and executing the next step, and when the ending signal of the interrupt event is not obtained, judging that the interrupt event is not ended.

And S40, obtaining a compensation refreshing waveform sequence according to the historical display data.

The present application provides two ways to obtain a compensation refresh waveform sequence according to the history display data, wherein one way is to obtain a compensation refresh waveform sequence according to the history display data, and the other way is to obtain a compensation refresh waveform sequence according to the history waveform data and the history color data, but the protection scope of the present application is not limited to the above-mentioned way of obtaining a compensation refresh waveform sequence. Because the actual color value of the pixel point when the ink screen displays the picture to be displayed after the interrupt event has errors with the target color value of the picture to be displayed, the afterimage appears, and in order to solve the problems, the application performs compensation refreshing by obtaining the compensation refreshing waveform sequence.

And S50, performing compensation refreshing by using the compensation refreshing waveform sequence.

According to the application, after the display picture is interrupted by the interrupt event, the compensation refreshing waveform sequence is obtained after the interrupt event is ended, and then the compensation refreshing waveform sequence is utilized to carry out compensation refreshing, so that the technical problem that the ink screen generates residual shadows after the interrupt event is ended is solved, the picture display effect is ensured, and the use experience of a user is improved.

Further, in an embodiment of the present application, the history display data includes: historical waveform data;

the step S40 includes:

and S401, obtaining a compensation refreshing waveform sequence according to the historical waveform data.

s4011, obtaining a first waveform sequence of a display image interrupted by the interrupt event from the historical waveform data;

s4012, acquiring an unapplied waveform sequence which is not applied to the ink screen when the first waveform sequence is interrupted by the interruption event;

s4013, the non-applied waveform sequence is a compensation refresh waveform sequence.

It should be noted that, when the first display screen is interrupted by the interrupt event, since the driving waveform sequence of the first display screen is not completely applied to the electronic ink screen, at this time, the portion of the driving waveform sequence of the first display screen, which is applied to the electronic ink screen, is the applied driving waveform sequence, and the portion of the driving waveform sequence of the first display screen, which is not applied to the electronic ink screen, is the non-applied driving waveform sequence, at this time, there is a difference between the target color value of the pixel point of the first display screen and the actual color value of the pixel point of the first display screen, and the reason for generating the difference is that the non-applied waveform sequence is not applied to the ink screen. In this embodiment, the non-applied waveform sequence is used as the compensation refresh waveform sequence, so that the technical problem that the ink screen generates ghost after the interrupt event is ended can be solved, the picture display effect is ensured, and the use experience of a user is improved.

In another embodiment of the present application, the history display data includes: historical waveform data and historical color data of pixel points on the ink screen under the driving of the historical waveform data;

the step S40 includes:

and step S402, obtaining a compensation refreshing waveform sequence according to the historical waveform data and the historical color data.

Referring to fig. 4, fig. 4 is a flowchart of step S402 of the display control method of the ink screen provided by the present application, specifically, the step S402 includes:

s4021, obtaining a second waveform sequence for driving the ink screen to display a current display picture from the historical waveform data;

s4022, obtaining a historical actual color value of a pixel point of the ink screen when displaying a previous display picture from the historical color data, wherein the previous display picture is a picture adjacent to the current display picture;

s4023, obtaining the actual color value of the pixel point on the current ink screen according to the second waveform sequence and the historical actual color value;

s4024, obtaining a target color value of a pixel point of an image to be displayed;

s4025, a compensation refreshing waveform sequence for enabling the pixel points on the ink screen to change from the actual color value to the target color value is obtained.

In order to solve the above problems, in the embodiment of the present application, a second waveform sequence for driving the ink screen to display the current display frame is obtained from the historical waveform data; obtaining a historical actual color value of a pixel point of the ink screen when displaying a previous display picture from the historical color data, wherein the previous display picture is a picture adjacent to the current display picture; wherein, because the display picture of the ink screen is interrupted by the interrupt event, the historical actual color value of the pixel point when the ink screen displays the previous display picture is different from the target color value of the pixel point when the ink screen displays the previous display picture, and the previous display picture can be the display picture of the display image interrupted by the interrupt event on the ink screen or the display picture after the display picture of the display image interrupted by the interrupt event on the ink screen; then, according to the second waveform sequence and the historical actual color value, the actual color value of the pixel point on the current ink screen is obtained; in the prior art, the actual color value of the pixel point on the current ink screen is obtained according to the second waveform sequence and the target color value of the pixel point when the ink screen displays the previous display picture, so that the obtained actual color value of the pixel point on the current ink screen is inaccurate, and the display effect is affected; then, obtaining a target color value of a pixel point of the image to be displayed; and finally, obtaining a compensation refreshing waveform sequence for enabling the pixel points on the ink screen to change from the actual color value to the target color value. The method and the device can obtain the actual color value of the pixel point on the current accurate ink screen, thereby obtaining the accurate compensation refreshing waveform sequence, and then carrying out compensation refreshing by utilizing the compensation refreshing waveform sequence, so that the technical problem that the ink screen generates residual shadows after the interrupt event is ended can be solved, the picture display effect is ensured, and the use experience of a user is improved.

s40232, inquiring the estimated color mapping relation according to the second waveform sequence and the historical actual color value to obtain an actual color value.

The estimated color mapping relationship is a preset corresponding relationship between a driving waveform sequence and pixel color values, and the corresponding actual color values can be queried based on the known driving waveform sequence and the historical actual color values. In one possible embodiment, the estimated color mapping relationship may be preset according to a set frame output frequency, so that after the ink screen is driven according to different waveform sequences (or driving frames) under different color values, the color value corresponding to the pixel point is established.

And S25, judging whether the interrupt event belongs to a preset event, and if not, executing the next step. If so, the next step is not performed and the process returns to step S10.

And step S30, judging whether the interrupt event is ended, and executing the next step if the interrupt event is ended.

In this embodiment, step S25 is inserted before step S30 of the present application, that is, it is first determined whether the interrupt event belongs to a preset event, if not, step S30 is executed again. Some interrupt events do not need to be subjected to compensation refreshing, so that whether the interrupt event belongs to a preset event or not is judged, if yes, compensation refreshing is not needed, and if not, refreshing is needed and step S30 is executed. Thereby being beneficial to improving the working efficiency of the ink screen.

In this embodiment, the preset event includes a screen clearing event, and the preset event may further include other event types that do not need to be compensated and refreshed, which are all within the protection scope of the present application. The screen clearing event refers to a refreshing display mode that clears displayed content in an ink screen to eliminate ghost before displaying a picture to be displayed, and the refreshing mode of the screen clearing event can be a GC16 refreshing mode, a GC4 refreshing mode, an INIT refreshing mode and an A2 refreshing mode.

step S10, recording history display data.

Step S20, detecting and recording an interrupt event, wherein the interrupt event is forced standby.

Step S33, judging whether the standby screen is needed to be displayed, if not, executing the next step. If so, the preset display operation can be performed in a mode of displaying the standby screen, and the preset display operation can be displaying the preset standby screen.

In this embodiment, step S33 is inserted before step S40 of the present application, that is, it is first determined whether the standby screen needs to be displayed, and if not, step S40 is executed again. When the standby picture is required to be displayed, the ink screen displays the standby picture and does not display other pictures, so that refreshing is not required; when the standby screen is not required to be displayed, step S40 is performed. Thereby being beneficial to improving the working efficiency of the ink screen.

Fig. 8 is a flowchart of a third embodiment of a display control method of an ink screen according to the present application, and referring to fig. 8, in this embodiment, the display control method of an ink screen includes:

s401, obtaining a compensation refreshing waveform sequence according to the historical waveform data;

if not, step S40 includes:

s402, a compensation refreshing waveform sequence is obtained according to the historical waveform data and the historical color data.

In this embodiment, step S36 is inserted before step S40 of the present application, that is, it is first determined whether the refresh mode of the display image interrupted by the interrupt event belongs to the fast refresh mode, if yes, step S40 adopts the operation of step S401, and if not, step S40 adopts the operation of step S402. The reason is that when the refresh mode of the display image interrupted by the interrupt event belongs to the fast refresh mode, the requirement of the ink screen on the display image quality is not high, and the operation mode of the step S401 is adopted, that is, the requirement of compensation refresh can be met by obtaining the compensation refresh waveform sequence according to the history waveform data; when the refresh mode of the display image interrupted by the interrupt event does not belong to the fast refresh mode, the ink screen has a higher requirement on the display image quality, and the operation mode of step S402 is adopted, that is, the compensation refresh waveform sequence is obtained according to the history waveform data and the history color data. The operation of step S401 is faster and takes less time, while the operation of step S402 takes relatively more time.

The fast refresh mode includes an A2 refresh mode and a DU refresh mode, and may be other fast refresh modes commonly used in the art.

In a specific implementation process, the method selects different acquisition modes of the compensation refresh waveform sequence by judging whether the refresh mode of the display image interrupted by the interrupt event belongs to the quick refresh mode, thereby being beneficial to improving the running speed of the ink screen.

Fig. 11 is a flowchart of a sixth embodiment of a display control method of an ink screen according to the present application, and referring to fig. 11, the difference between the present embodiment and the image processing method provided in fig. 1 is that, based on the image processing method provided in fig. 1, the display control method includes:

the method further comprises the following steps before the step S50:

s41, acquiring a target color value of a pixel point of an image to be displayed;

s43, judging whether the target color value of the pixel point of the image to be displayed belongs to a preset color set;

if yes, said step S50 includes:

if not, the step S50 includes:

The first transformation process includes a frame subtraction process, and of course, the first transformation process may also include other processing manners in the prior art, so long as the number of driving frames of the first compensation refresh waveform sequence is smaller than the number of driving frames of the compensation refresh waveform sequence or the driving duration of the first compensation refresh waveform sequence is smaller than the driving duration of the compensation refresh waveform sequence.

The second transformation process includes a framing process, and of course, the second transformation process may also include other processing manners in the prior art, so long as the number of driving frames of the second compensation refresh waveform sequence is greater than the number of driving frames of the compensation refresh waveform sequence or the driving time of the second compensation refresh waveform sequence is greater than the driving time of the compensation refresh waveform sequence.

From the above, when the target color value of the pixel point of the image to be displayed is not within the preset color set, normal compensation refreshing is performed at this time or the first conversion processing is performed on the compensation refreshing waveform sequence to obtain a first compensation refreshing waveform sequence, the first compensation refreshing waveform sequence is used for compensation refreshing, and when the target color value of the pixel point of the image to be displayed is not within the preset color set, the second conversion processing is performed on the compensation refreshing waveform sequence to obtain a second compensation refreshing waveform sequence, and the second compensation refreshing waveform sequence is used for compensation refreshing.

The inventor finds that some color particles are not controlled to generate the afterimage after the interrupt event occurs in the practical process, when the target color value of the pixel point of the image to be displayed belongs to high gray scale, the phenomenon of generating the afterimage after the interrupt event occurs is smaller, and when the target color value of the pixel point of the image to be displayed belongs to low gray scale, the phenomenon of generating the afterimage after the interrupt event occurs is larger. Therefore, in one embodiment, the preset color set may be a low-gray-scale color set, for example, the gray scale range is generally from 0 to 255, where the gray scale value is 0 is black, and the gray scale value is 255, so that the low-gray-scale color set may be any set between 128 and 0, and at this time, when the target color value of the pixel point of the image to be displayed is within the low-gray-scale color set, normal compensation refreshing is performed or frame reduction processing is performed on the compensation refreshing waveform sequence to obtain a first compensation refreshing waveform sequence, and compensation refreshing is performed by using the first compensation refreshing waveform sequence, so that normal compensation or reduction compensation processing is performed on the pixel point of the image to be displayed with a darker color, which is beneficial to reduce the generation of a residual shadow; and when the target color value of the pixel point of the image to be displayed does not belong to the low-gray-scale color set, framing the compensation refreshing waveform sequence to obtain a second compensation refreshing waveform sequence, and performing compensation refreshing by using the second compensation refreshing waveform sequence, so that the pixel point of the image to be displayed with lighter color is subjected to reinforcement compensation, and the generation of afterimages is reduced.

Fig. 12 is a flowchart of a seventh embodiment of a display control method of an ink screen according to the present application, and referring to fig. 12, the difference between the present embodiment and the image processing method provided in fig. 1 is that, based on the image processing method provided in fig. 1, the display control method includes:

the method further comprises the following steps before the step S50:

s45, acquiring a refresh mode of at least one display picture in the latest display pictures and a refresh mode of an image to be displayed, wherein the latest display pictures comprise the display pictures interrupted by the interrupt event and the display pictures positioned behind the display pictures interrupted by the interrupt event;

s47, judging whether the refresh mode of the at least one display picture has a refresh mode different from the refresh mode of the image to be displayed;

if not, executing step S50;

if yes, said step S50 comprises:

Since the refresh mode of at least one display screen in the latest display screen is not necessarily the same as the refresh mode of the image to be displayed, in order to improve the compensation effect, the application adopts different compensation strategies for the case that the refresh mode is changed and the case that the refresh mode is not changed. Specifically, when the refresh mode of the at least one display picture does not have a refresh mode different from the refresh mode of the image to be displayed, that is, the refresh mode is not changed, compensation refresh is performed by using the compensation refresh waveform sequence, and when the refresh mode of the at least one display picture has a refresh mode different from the refresh mode of the image to be displayed, that is, the refresh mode is changed, periodic compensation refresh is performed by using the compensation refresh waveform sequence with T as a time interval, and the compensation effect is poor due to the fact that the refresh mode is changed, the compensation effect can be improved by adopting a periodic compensation refresh mode.

For example, the latest display screen includes 4 screens, where the 4 screens are a display screen interrupted by the interrupt event, a current display screen, and two other display screens located between the display screen interrupted by the interrupt event and the current display screen, in one embodiment, a refresh mode of the current display screen and a refresh mode of an image to be displayed are acquired, and whether the refresh mode of the current display screen is different from the refresh mode of the image to be displayed is determined, if not, the step is performed: and carrying out compensation refreshing by using the compensation refreshing waveform sequence, and if so, carrying out periodic compensation refreshing by using the compensation refreshing waveform sequence with T as a time interval. In another embodiment, the refresh mode of 3 display frames in the latest display frame and the refresh mode of the image to be displayed are obtained, for example, the refresh mode of 3 display frames is the refresh mode of the current display frame and the refresh modes of the remaining two display frames located between the display frame interrupted by the interrupt event and the current display frame, and it is determined whether the refresh mode of 3 display frames in the latest display frame has a refresh mode different from the refresh mode of the image to be displayed, if not, the step is executed: and carrying out compensation refreshing by using the compensation refreshing waveform sequence, and if so, carrying out periodic compensation refreshing by using the compensation refreshing waveform sequence with T as a time interval. Where T is in milliseconds, T may be 1 millisecond, 2 milliseconds, 4 milliseconds, etc.

Further, in this embodiment, on the basis of the foregoing, the step of performing periodic compensation refresh with T as a time interval by using the compensation refresh waveform sequence includes:

s51, performing third transformation processing on the compensation refresh waveform sequence to obtain a third compensation refresh waveform sequence, wherein the number of driving frames of the third compensation refresh waveform sequence is smaller than that of the compensation refresh waveform sequence or the driving duration of the third compensation refresh waveform sequence is smaller than that of the compensation refresh waveform sequence;

s52, using the third compensation refresh waveform sequence to carry out periodic compensation refresh at the time interval of T.

In order to avoid the situation of excessive compensation, a third conversion process may be performed on the compensation refresh waveform sequence to obtain a third compensation refresh waveform sequence, and then the third compensation refresh waveform sequence is used to perform periodic compensation refresh at a time interval of T.
