For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following detailed description of specific embodiments thereof is given with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the matters related to the present application are shown in the accompanying drawings. Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The above-described process may be terminated when its operations are completed, but may have additional steps not included in the drawings. The processes described above may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a driving compensation-based ink screen display control method according to an embodiment of the present application, where the driving compensation-based ink screen display control method according to the embodiment of the present application may be implemented by a driving compensation-based ink screen display control device, and the driving compensation-based ink screen display control device may be implemented by hardware and/or software and integrated in a driving compensation-based ink screen display control device.
The following description will be made taking as an example an ink panel display control method in which the ink panel display control device based on the drive compensation executes the ink panel display control method based on the drive compensation. Referring to fig. 1, the driving compensation-based ink screen display control method includes:
s101: and determining a first color value corresponding to each image pixel based on a first waveform sequence corresponding to each image pixel in the image to be displayed.
The image to be displayed provided in this embodiment has a plurality of image pixels, and the image pixels on the image to be displayed correspond to the screen pixels on the ink screen one by one, and the image to be displayed can be obtained by processing a screen displayed according to needs based on a processor in the ink screen display control device.
After determining an image to be displayed on an ink screen, determining a first waveform sequence corresponding to each image pixel point in the image to be displayed, wherein each first waveform sequence comprises a plurality of driving frames corresponding to the corresponding image pixel point, and the driving frames in each first waveform sequence are ordered according to a set order. Optionally, the plurality of driving frames of the image pixel point on the image to be displayed may be determined according to an intermediate process required for changing the current color value of the screen pixel point corresponding to the image pixel point to the second color value of the image pixel point, where different intermediate processes correspond to different driving frames. Or, the first waveform sequence of the image pixel point on the image to be displayed can be determined according to the waveform sequence required by the color change from the current color value of the screen pixel point corresponding to the image pixel point to the second color value of the image pixel point, and different waveform sequences correspond to different color changes. The first color value may be understood as a color value (estimated color value) displayed by each screen pixel point of the image to be displayed on the screen pixel point of the display screen when the ink screen is driven to display according to the first waveform sequence, and the second color value may be understood as a color (target color value) of the image to be displayed corresponding to the image pixel point.
In one possible embodiment, the driving frame of each image pixel point may be determined based on a preset waveform file (may be provided in the form of a waveform file), that is, for one pixel point on the image to be displayed, according to an intermediate process that needs to be passed from a current color value (a color value that is currently displayed by the corresponding screen pixel point of the ink screen) to a second color value (a color value that is corresponding to the image pixel point to be displayed), a corresponding waveform sequence is determined from the waveform file, where the waveform sequence is a first waveform sequence, and in the first waveform sequence, a plurality of driving frames that instruct to drive the corresponding thin film transistor on the corresponding screen pixel point of the ink screen are included, and sequentially drive the thin film transistor according to different driving frames in the first waveform sequence, where the corresponding screen pixel point will undergo a corresponding intermediate process, and the currently displayed color value is converted to the second color value.
In one possible embodiment, the first waveform sequence corresponding to each image pixel in the image to be displayed may be a waveform sequence after display acceleration processing, for example, the first waveform sequence is driven at a set frame output frequency for the tft matrix, where the frame output frequency is obtained by performing an up-conversion processing on an original output frequency (which may be provided by an ink screen manufacturer) of the tft matrix. In the related art, after a first waveform sequence corresponding to an image to be displayed is obtained, the thin film transistor matrix is controlled according to the first waveform sequence directly based on the original output frequency of the thin film transistor matrix, so that the image displayed on the ink screen is updated from the current display image to the image to be displayed. Because the thin film transistor matrix is controlled so that when the pixel point on the screen is converted from the current color value to the second color value, a plurality of intermediate processes are undergone, correspondingly, the thin film transistor matrix needs to be driven through a plurality of driving frames, and when the thin film transistor matrix is driven and controlled according to the original output frequency, the time required for realizing the conversion of the second color value is long. For example, the A2 refresh mode of the ink screen supports display of two colors of black and white, a waveform sequence from black to white or from white to black requires approximately 10 driving frames, and assuming that the original output frequency of the TFT is 50Hz, the driving time of one driving frame is 20ms, and the total driving time required is 200ms, while the GC16 refresh mode of the ink screen supports display of 16 gradation, a waveform sequence from one gradation to another requires approximately 30 to 40 driving frames, and the total driving time required for one waveform sequence is 600ms to 800ms. Due to the display principle of the electronic ink screen, the intermediate process of updating the pixel points of the screen from one color to another color is more, and the time required is longer, so that the problems of low screen updating speed, slow user interaction response, long operation waiting time and the like are caused. The original output frequency of the thin film transistor matrix can be improved, the problem of display effect reduction caused by improvement of the output frequency is compensated in a driving compensation mode, and on the premise of ensuring the display effect, the image updating efficiency is effectively improved, and the user experience is optimized. For example, the up-conversion processing may be performed on the original output frequency according to a set up-conversion ratio (for example, 1.1-2 times), for example, the up-conversion ratio is set to 2 times, when the original output frequency is 50Hz, the processing speed of the original driving frame is 50 frames per second, and the frame output frequency of 100Hz is obtained after the up-conversion processing is performed on the original output frequency, then the processing speed of the driving frame is increased to 100 frames per second, the driving time of one driving frame is increased from 20ms to 10ms, for example, the total driving time corresponding to a waveform sequence including 10 driving frames is shortened from 200ms to 100ms, for example, the GC16 refresh mode, the total driving time corresponding to a waveform sequence including 30-40 driving frames is shortened from 600ms to 800ms to 300ms to 400ms, and the screen update efficiency is obviously accelerated.
In one possible embodiment, the first waveform sequence corresponding to each image pixel in the image to be displayed includes one or more key driving frames, that is, each first waveform sequence includes a plurality of key driving frames corresponding to the corresponding image pixel, and the plurality of key driving frames in each first waveform sequence are ordered according to a set order. In one possible embodiment, the key driving frame of each image pixel point may be determined based on preset key frame waveform data, when determining the first waveform sequence corresponding to each image pixel point in the image to be displayed based on the preset key frame waveform data, the key driving frame corresponding to each image pixel point in the image to be displayed may be determined according to the current display image and the image to be displayed based on the preset key frame waveform data, and the first waveform sequence corresponding to each image pixel point in the image to be displayed may be determined based on the key driving frame. In the key frame waveform data (key frame waveform file provided in the form of a waveform file) provided in this embodiment, key driving frames corresponding to the conversion between different color values (i.e., driving one color value to another color value on a screen pixel point) are recorded, and optionally, the key frame waveform data may also record a driving sequence between a plurality of key driving frames converted between different colors. It can be understood that when the screen pixel points corresponding to the ink screen are sequentially driven according to the key driving frames according to the driving sequence (the driving of the screen pixel points can be applied by driving the thin film transistors corresponding to the screen pixel points, for example, applying the voltages corresponding to the key driving frames to the corresponding thin film transistors so as to move the pigment particles to the designated positions), the screen pixel points undergo an intermediate process of corresponding color change, and after the driving of one or more key driving frames is sequentially completed, the screen pixel points will display the color corresponding to the second color value. In an exemplary embodiment, after determining an image to be displayed that needs to be displayed on the ink screen, determining a current display image that is currently displayed on the ink screen, determining one or more key driving frames corresponding to each image pixel point in the image to be displayed under the current display image and the image to be displayed based on a preset key frame image waveform file, and driving sequences of the key driving frames in the same image pixel point. Further, a first waveform sequence corresponding to each image pixel in the image to be displayed is determined based on one or more key drive frames corresponding to each image pixel, and each first waveform sequence comprises one or more key drive frames which realize sequential ordering of corresponding color value conversion. In the related art, assuming that the frame output frequency of the display screen is 50Hz, that is, the driving time of one driving frame is 20ms, and assuming that the number of original driving frames corresponding to 4 original waveform sequences of an image to be displayed (including 4 image pixels) determined based on the original waveform file is 30 frames, the driving time for driving the ink screen to display the image to be displayed based on the original waveform sequences is 600ms. The first waveform sequences composed of key driving frames are determined, the number of key driving frames corresponding to 4 first waveform sequences of an image to be displayed is respectively 15 frames, 16 frames and 18 frames, the number of driving frames corresponding to 4 second waveform sequences obtained after the first waveform sequences are subjected to frame-supplementing alignment treatment is 18 frames, the driving time for driving the ink screen to display the image to be displayed based on the second waveform sequences is 360ms, and the refreshing efficiency of the ink screen is obviously improved.
In one possible embodiment, the key frame waveform data provided by the scheme records key driving frames corresponding to the screen pixel points on the ink screen changing from one color value to another color value, wherein the key driving frames are determined based on the driving effect of each original driving frame in an original waveform file (which can be provided in the form of a waveform file) corresponding to the ink screen, and the image pixel points in the image to be displayed correspond to the screen pixel points on the ink screen one by one. The original waveform file may be provided by a vendor of the ink screen, that is, waveform sequences corresponding to the conversion of different color values are defined by the vendor in advance and recorded in the original waveform file, and the different waveform sequences include a plurality of original driving frames. It should be explained that in the prior art, the driving of the ink screen is performed based on the original waveform file, that is, after the image to be displayed is determined, the control waveform sequence of each image pixel point is determined based on the original waveform file, the image to be displayed and the current display image, and the thin film transistor (TFT, thin Film Transistor) matrix is directly controlled according to the control waveform sequences, and the thin film transistors are sequentially driven according to different original driving frames, so that pigment particles in the microcapsules are moved to the designated positions, and the image displayed by the ink screen is converted from the current display image to the image to be displayed. Because the ink screen manufacturer cannot predict the use scene of the ink screen, the pre-defined waveform sequence contains non-critical original driving frames besides the original driving frames playing a key role in image display, wherein the critical original driving frames can be obtained by performing experimental observation on waveform sequences corresponding to different color value conversion, and whether the original driving frames can be used as the key driving frames or not is determined according to the driving effect (namely, the consistency degree of the converted color values and the predicted color values), namely, the original driving frames with the most obvious driving effect can be determined as the key driving frames, and the original driving frames with the insignificant driving effect are non-key driving frames. In addition, since the current color value of each screen pixel point of the current ink screen may be different, and the second color value of each image pixel point of the image to be displayed to be updated is also different, the waveform sequence content and length that each screen pixel point on the ink screen actually needs to be driven from the current color to the color to be updated are also different, but since the ink screen update is a unified process, in order to keep the update time of all the image pixel points consistent, a short waveform sequence may be inserted into some invalid frames to keep the drive time of all the waveform sequences and the longest waveform sequence consistent. In general, the driving voltage indicated in the invalid frame is zero or a first set voltage value, and correspondingly, when the screen pixel (thin film transistor) is driven based on the invalid frame, the color value on the corresponding screen pixel remains unchanged. Based on the above, the key frame waveform data of the scheme can be created based on the key driving frames by observing the driving effects of different waveform sequences and different original driving frames in the original waveform file and determining the key driving frames, the non-key driving frames and the invalid driving frames in each waveform sequence. Optionally, the driving effects of different waveform sequences and different original driving frames in the original waveform file can be observed under different use scenes, key driving frames, non-key driving frames and invalid driving frames in the waveform sequences under different use scenes are determined, and key frame waveform data corresponding to different use scenes are created based on the key driving frames. When determining the first waveform sequence corresponding to each image pixel point in the image to be displayed, determining corresponding key frame waveform data according to the current use scene, and determining the key driving frame corresponding to each image pixel point in the image to be displayed according to the determined key waveform file.
By the above-mentioned mode of improving the output frequency of the thin film transistor matrix and/or screening the key driving frame, after improving the image refreshing efficiency of the ink screen, the image display effect is reduced after acceleration, so as to ensure the image display effect, the scheme performs driving compensation on the first waveform sequence according to the difference between the first color value and the second color value after driving according to the first waveform sequence. Based on the first waveform sequence, after the first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, the first color value corresponding to each image pixel point is determined according to the first waveform sequence.
In one possible embodiment, the determining of the first color value may be performed according to a preset estimated color mapping relationship, where the estimated color mapping relationship records a color value actually displayed by a color value corresponding to a pixel point after the pixel point performs screen driving on different color values according to different waveform sequences (or driving frames). The estimated color mapping relationship may be recorded in the form of a mapping table or a mapping formula. The color value displayed after driving one screen pixel point can be estimated according to the estimated color mapping relation, namely, the relation is determined according to the estimated color for each image pixel point, and the corresponding first color value after driving the ink screen according to the first waveform sequence under the current color value is determined. In one possible embodiment, the estimated color mapping relationship may be set up in advance according to the set frame output frequency, and 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 set up.
S102: and determining a compensation frame from the first color value to the corresponding second color value of each image pixel point according to the first color value and the corresponding second color value of each image pixel point in the image to be displayed.
For example, after determining the first color value corresponding to each image pixel, for each image pixel, a compensation frame from the first color value to the second color value corresponding to the image pixel is determined according to the first color value and the second color value.
For example, a color difference of a first color value relative to a second color value of each screen pixel point when driving the thin film transistor matrix in a first waveform sequence to cause the ink screen to display an image to be displayed at a frame output frequency to the thin film transistor matrix is determined, and a compensation frame is determined. It will be appreciated that when the ink screen is driven based on the compensation frame, the color value displayed by the corresponding screen pixel will change from a first color value to a second color value or close to the second color value (closer to the second color value than before the compensation process is driven).
S103: and performing driving compensation processing on the first waveform sequence corresponding to each image pixel point by using the compensation frame to obtain a second waveform sequence corresponding to each image pixel point.
After determining the compensation frame corresponding to each image pixel, the first waveform sequence corresponding to each image pixel is subjected to driving compensation processing by using the compensation frame to obtain the second waveform sequence corresponding to each image pixel. At this time, the second waveform sequence includes the driving frame and the corresponding compensation frame in the original first waveform sequence.
In one possible embodiment, the compensation frame may be one or more compensation driving frames for adding to the first waveform sequence, where the first color value is a first color value corresponding to a pixel of the screen when the ink screen is driven according to all driving frames in the corresponding first waveform sequence, and correspondingly, the compensation frame is added to the first waveform sequence when the driving compensation process is performed on the first waveform sequence. The compensation frame may also be a second number of modified drive frames for replacing the last first number of original drive frames of the first waveform sequence, wherein the second number of modified drive frames for replacing the original drive frames is larger than the first number of replaced drive frames (the second number of modified drive frames-the first number of replaced drive frames being equal to or larger than 1), i.e. the second number is larger than the first number. At this time, the first color value is a first color value corresponding to the ink screen according to the first driving frame to the first last number of the previous driving frames in the first waveform sequence (for example, when five correction driving frames are set, the first color value corresponding to the ink screen after the ink screen is driven according to the first driving frame to the third last driving frame in the first waveform sequence is set, and when three correction driving frames are set, the first color value corresponding to the ink screen after the ink screen is driven according to the first driving frame to the second last driving frame in the first waveform sequence is set. Correspondingly, when the first waveform sequence is subjected to the drive compensation processing, the last first number of drive frames in the first waveform sequence is replaced by the second number of correction drive frames, for example, when 3-5 correction drive frames are set and the number of replaced original drive frames is two, when the first waveform sequence is subjected to the drive compensation processing, the last two drive frames in the first waveform sequence are replaced by 3-5 correction drive frames.
S104: and driving the ink screen to display the image to be displayed based on the second waveform sequence.
After determining the second waveform sequences corresponding to the pixels of each image, the ink screen is driven according to the second waveform sequences, so that the image displayed by the ink screen is converted from the current display image to the image to be displayed. That is, for each image pixel, the thin film transistor matrix is controlled based on the driving frame in the corresponding second waveform sequence (including all or part of the driving frame in the original first waveform sequence and the compensation frame), that is, the thin film transistor is controlled based on the driving frame in the second waveform sequence in turn, so that the corresponding screen pixel realizes the corresponding color change intermediate process, and the ink screen is driven to display the image to be displayed.
In one possible embodiment, the ink screen display control method based on the driving compensation further includes: determining a current third color value of each screen pixel point of the ink screen in response to the image to be displayed as a final display image; determining a third waveform sequence from the third color value to the corresponding second color value of each screen pixel according to the third color value corresponding to each screen pixel and the image to be displayed; and driving the ink screen to display the image to be displayed based on the third waveform sequence.
In the ink screen display control method provided by the scheme, in the process of displaying the intermediate display image (the image to be displayed is the intermediate display image), the ink screen can be driven to display the image to be displayed based on the second waveform sequence, so that the display effect of the intermediate display image on the display screen is close to that of the image to be displayed. When the image to be displayed is the final display image, in order to ensure that the display effect of the final display image on the display screen is closer to or consistent with that of the image to be displayed, the ink screen can be driven again according to the color difference between the third color value (display color value) of each image pixel point and the final display image after the ink screen is driven based on the second waveform sequence, so that the final display image displayed on the display screen is closer to or consistent with that of the image to be displayed.
Whether the image to be displayed is a final display image or not can be judged according to whether other images to be displayed which are to be extracted and displayed exist in the image to be displayed cache queue, namely, when the other images to be displayed do not exist in the image to be displayed cache queue, the current image to be displayed can be determined to be the final display image. And the timing can be performed after the ink screen is driven to display the images to be displayed according to the second waveform sequence, and when the images to be displayed are continuously displayed and accumulated for a set time length and other highlights are not updated to be displayed or a new image to be displayed is received, the current image to be displayed can be determined to be the final image to be displayed. For example, when the ink screen is used to display video, the image to be displayed in the video playing process is an intermediate display image (after the intermediate display image, the next frame of image to be displayed needs to be updated in a set time), and when the video playing is finished or paused, the corresponding image to be displayed is a final display image (the display content on the display screen does not need to be updated in the set time). It will be appreciated that the determination of whether the image to be displayed is the final display image may be other methods, and the present solution is not limited.
After the ink screen is driven to display the image to be displayed based on the second waveform sequence, if the image to be displayed is determined to be the final display image, determining a current third color value of each screen pixel point of the current ink screen, determining a third waveform sequence from the third color value to the corresponding second color value of each screen pixel point by using the original waveform file according to the color difference between the third color value corresponding to each screen pixel point and the image to be displayed, and driving the ink screen to display the image to be displayed based on the third waveform sequence. According to the scheme, when the image to be displayed is the final display image, the ink screen is driven through the third waveform sequence determined according to the original file, so that the display effect of the final display image is ensured.
In one possible embodiment, when determining that the image to be displayed is the final display image, if the ink screen is not driven to display the image to be displayed based on the second waveform sequence at this time, determining a third waveform sequence directly according to a third color value corresponding to each screen pixel point and the image to be displayed, and driving the ink screen to display the image to be displayed based on the third waveform sequence, without displaying the image to be displayed based on the second waveform sequence, so as to increase the image display speed. In one possible embodiment, before driving the ink screen based on the second waveform sequences, it is determined whether each of the second waveform sequences is aligned, if not, the second waveform sequences are aligned by using the invalid frame, and then the ink screen is driven based on the aligned second waveform sequences.
In one embodiment, after the first waveform sequence is compensated, there may be a situation that the compensation capability is insufficient, and the ink screen may not be able to accurately display the corresponding target color, and the estimated third color value after the compensation needs to be estimated as the actual display color. Based on the above, after obtaining the second waveform sequence corresponding to each image pixel point or driving the ink screen to display the image to be displayed based on the second waveform sequence to drive the ink screen to display the image to be displayed, the ink screen display control method based on the driving compensation further comprises: when the ink screen display is driven based on the second waveform sequence, determining a predicted third color value corresponding to each image pixel point, namely determining that each image pixel point in the image to be displayed drives the ink screen to display the corresponding predicted third color value according to all driving frames in the corresponding second waveform sequence, wherein the predicted third color value can be used as a current color value corresponding to the screen pixel point on the ink screen for determining the image to be displayed of the next frame (the processing flow of the ink screen display control method based on driving compensation of the next round) of the ink screen display.
And the first waveform sequence of each image pixel point is driven and compensated by the compensation frame, so that the image display quality is effectively ensured. When the screen refreshing speed of the ink screen is improved, the driving compensation of the first waveform sequence is adopted, so that the situation that the difference between the display color of the ink screen and the target color is overlarge is reduced while the screen refreshing speed is improved, and the screen display quality is ensured.

For example, when more than 2 corrected driving frames are set to replace 2 driving frames, when determining the first color value, specifically, determining that each image pixel point in the image to be displayed drives the ink screen based on the first driving frame to the 3 rd driving frame in the corresponding first waveform sequence under the current output frequency of the thin film transistor matrix, and then, after the ink screen corresponds to the first color value of the screen pixel point.
In one possible embodiment, the determining of the first color value may be performed according to a preset pre-estimated color mapping relationship, that is, for each image pixel, according to the pre-estimated color determining relationship, determining, under the current color value, a corresponding first color value after driving the ink screen according to a first driving frame to a first last number of previous driving frames in the first waveform sequence.
S203: and determining a compensation frame from the first color value to the corresponding second color value of each image pixel point according to the first color value and the corresponding second color value of each image pixel point in the image to be displayed.
In this embodiment, the compensation frames include a second number of modified drive frames for replacing a last first number of drive frames of the first waveform sequence, wherein the second number is greater than the first number. Based on the above, after determining the first color value corresponding to each image pixel, determining the second color value corresponding to each image pixel in the image to be displayed, and further determining the second number of correction driving frames of each image pixel of the image to be displayed according to the first color value and the corresponding second color value of each image pixel.

For each image pixel of the image to be displayed, a second number of corrected driving frames from the corresponding first color value to the corresponding second color value is determined. The determination of the correction driving frame may be performed based on the waveform file, that is, a second number of driving frames corresponding to the first color value to the second color value are determined in the waveform file, and the corresponding driving frames are used as correction driving frames, and the correction driving frame may be further determined based on the estimated color mapping relationship, that is, a second number of driving frames corresponding to the first color value to the second color value are determined based on the estimated color mapping relationship, and the corresponding driving frames are used as correction driving frames.

At this time, the driving frames in the first waveform sequence include, in addition to the first to last first number of previous driving frames in the original first waveform sequence, a second number of corrected driving frames replacing the first to last number of driving frames in the original last, for example, when two corrected driving frames are set, the first color value is determined based on the first to last third driving frames in the first waveform sequence, and the driving frames in the second waveform sequence include two corrected driving frames replacing the two driving frames in the original last in addition to the first to last third driving frames in the corresponding first waveform sequence.

In one possible embodiment, the determining the compensation frame from the first color value to the corresponding second color value for each image pixel in the image to be displayed according to the first color value and the corresponding second color value for each image pixel provided by the scheme includes:
determining a compensation strategy for the first waveform sequence according to a set driving compensation mode; and based on the compensation strategy, determining a compensation frame from the first color value to the corresponding second color value of each image pixel point in the image to be displayed according to the first color value and the corresponding second color value of each image pixel point.
The compensation strategy provided in this embodiment is used to indicate the compensation intensity for compensating the first waveform sequence, and different compensation strategies correspond to different compensation intensities. After determining the first color value corresponding to each image pixel, the driving compensation mode set currently is determined, and the compensation strategy corresponding to the driving compensation mode currently is determined. Further, according to the determined compensation intensity corresponding to the driving compensation strategy, a compensation frame from the first color value to the corresponding second color value of each image pixel point in the image to be displayed is determined according to the first color value and the corresponding second color value of each image pixel point. The stronger the compensation intensity corresponding to the driving compensation strategy, the larger the number of compensation frames, that is, the stronger the compensation intensity on the first waveform sequence, and the color value displayed by the driving ink screen according to the second waveform sequence obtained after compensation is closer to the second color value (target color value). According to the scheme, the first waveform sequence is subjected to drive compensation with different compensation intensities through the compensation strategies under different drive compensation modes, so that the requirements of users on picture display quality and picture display speed under different use scenes are met, and the user experience is optimized.
In one possible embodiment, the drive compensation mode may be set automatically by the ink screen display control device, e.g., the ink screen display control device may be determined based on the current operating mode of the ink screen. Optionally, a driving compensation mode with lower compensation intensity can be set for a working mode with higher requirement on the screen refresh speed, for example, different driving compensation modes corresponding to different driving compensation modes under different working modes such as a reading mode, a picture mode, a web page mode, a video mode and the like, and the compensation intensity corresponding to the compensation strategy of the corresponding driving compensation mode is sequentially reduced.
In one possible embodiment, the driving compensation mode may also be set according to a compensation mode setting operation in which a user sets the driving compensation mode of the ink screen display control device. Based on this, the ink screen display control method based on the driving compensation provided by the scheme further comprises the following steps: and updating the driving compensation mode according to the received compensation mode setting operation.
For example, a driving compensation configuration interface for configuring driving compensation modes may be provided on the ink screen display control device, and a selection list of different driving compensation modes may be provided on the driving compensation configuration interface. When the user needs to configure the driving compensation mode, the user can select the required driving compensation mode on the driving compensation configuration interface, or configure the corresponding driving compensation mode for different working modes, or configure the corresponding driving compensation mode for different time periods, so as to trigger the compensation mode setting operation. After receiving the compensation mode setting operation, the drive compensation mode is updated according to the selection of the drive compensation mode by the compensation mode setting operation. According to the scheme, the driving compensation mode is updated according to the compensation mode setting operation triggered by the user, so that the flexible setting requirements of the user on the picture display quality and the picture display speed under different use scenes are met, and the user experience is optimized.
In one possible embodiment, the ink screen display control method based on driving compensation provided by the present solution further includes: under the condition that a first compensation switch of the ink screen is turned on, determining to carry out driving compensation processing on a first waveform sequence corresponding to each image pixel point by using a compensation frame; and/or under the condition that a second compensation switch of the ink screen is turned on, determining that the ink screen is driven by a third waveform sequence to perform color compensation when the image to be displayed is the final display image.
It should be explained that the first compensation switch is used for controlling whether the first waveform sequence needs to be driven and compensated, and the second compensation switch is used for controlling whether the ink screen needs to be driven by the third waveform sequence to be compensated.

And under the condition that the on-off state of the first compensation switch of the ink screen is closed, determining that driving compensation processing is not needed to be carried out on the first waveform sequences corresponding to the image pixels by using the compensation frames, namely after determining the first waveform sequences corresponding to each image pixel in the image to be displayed, driving the ink screen to display the image to be displayed directly based on the first waveform sequences.
The second compensation switch comprises an on state and an off state, when the on state of the second compensation switch of the ink screen is the on state, the ink screen is driven by a third waveform sequence to perform color compensation when the image to be displayed is determined to be the final display image, namely, the current third color value of each screen pixel point of the ink screen is determined in response to the fact that the image to be displayed is the final display image, and the third waveform sequence from the third color value to the corresponding second color value of each screen pixel point is determined according to the third color value corresponding to each screen pixel point and the image to be displayed, and then the ink screen is driven to display the image to be displayed based on the third waveform sequence. And under the condition that the on-off state of the second compensation switch of the ink screen is closed, determining whether the image to be displayed is the final display image or not is not needed, and driving the ink screen to perform color compensation by using the third waveform sequence is also not needed.

If the screen refresh rate of the ink screen is accelerated by screening the key driving frames, the driving frames of the first waveform sequence are key driving frames, and the numbers of the key driving frames corresponding to the 4 first waveform sequences of the image to be displayed are respectively 15 frames, 16 frames and 18 frames, and the second number of the correction driving frames (taking 3 correction driving frames as an example to replace 2 key driving frames) is used for performing driving compensation processing on the first waveform sequence, and at this time, the numbers of the driving frames corresponding to the second waveform sequence are respectively 16 frames (13 key driving frames+3 correction driving frames), 17 frames (14 key driving frames+3 correction driving frames) and 19 frames (16 key driving frames+3 correction driving frames). After the complementary frame alignment processing is performed on the second waveform sequences, the number of driving frames of the obtained 4 second waveform sequences is 19 frames (13 key driving frames+3 correction driving frames+3 invalid frames), 19 frames (14 key driving frames+3 correction driving frames+2 invalid frames) and 19 frames (16 key driving frames+3 correction driving frames), and then the driving time for driving the ink screen to display the image to be displayed based on the second waveform sequences is 380ms, so that the refreshing efficiency of the ink screen is obviously improved. If the image refreshing speed of the ink screen is accelerated by increasing the output frequency of the thin film transistor matrix, the original output frequency is doubled, at this time, the output frequency of the thin film transistor matrix is 100Hz, that is, the driving time of one driving frame is 10ms, the number of driving frames corresponding to 4 first waveform sequences of the image to be displayed (including 4 image pixels) is determined to be 30 frames based on the original waveform file, the second number of correction driving frames (taking 3 correction driving frames as an example to replace 2 key driving frames) is used for carrying out driving compensation processing on the first waveform sequences to obtain the second waveform sequences, and the number of driving frames corresponding to the 4 second waveform sequences is 31 frames, at this time, the driving time of driving the ink screen to display the image to be displayed is 310ms, so that the refreshing efficiency of the ink screen is obviously improved. According to the method, the first waveform sequence is subjected to driving compensation processing through the second number of correction driving frames, so that after the ink screen is driven to change from the current color value to the first color value, the color displayed at last on each screen pixel point is ensured to be consistent with the target color based on the change from the first color value to the second color value of the second number of correction driving frames, and the image display quality is ensured.
And the first waveform sequence of each image pixel point is driven and compensated by the compensation frame, so that the image display quality is effectively ensured. When the screen refreshing speed of the ink screen is improved, the driving compensation of the first waveform sequence is adopted, so that the situation that the difference between the display color of the ink screen and the target color is overlarge is reduced while the screen refreshing speed is improved, and the screen display quality is ensured. Meanwhile, when the first waveform sequence is subjected to driving compensation, a second number of corrected driving frames are determined according to driving requirements of first color values and second color values corresponding to each image pixel point after driving from a first original driving frame to a first last number of previous driving frames in the first waveform sequence of the first waveform sequence, and the first waveform sequence is subjected to driving compensation, so that the accuracy of the display image after display acceleration is effectively ensured.
