In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the matters relating to the present application are shown in the drawings. Before discussing exemplary embodiments in greater detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously.

The processes described above may correspond to methods, functions, procedures, subroutines, subprograms, and the like.
Fig. 1 is a flowchart of a driving compensation based ink screen display control method provided in an embodiment of the present application, where the driving compensation based ink screen display control method provided in an embodiment of the present application may be executed by a driving compensation based ink screen display control device, and the driving compensation based ink screen display control device may be implemented in a hardware and/or software manner and integrated in a driving compensation based ink screen display control apparatus.
The following description will be given taking as an example an ink panel display control method in which the drive compensation-based ink panel display control apparatus performs drive compensation-based ink panel display control. Referring to fig. 1, the ink screen display control method based on driving compensation includes:
s101: and determining a first color value corresponding to each image pixel point based on the first waveform sequence corresponding to each image pixel point in the image to be displayed.
The image to be displayed provided by 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 to one, and the image to be displayed can be obtained by processing a picture to be displayed according to needs by a processor in the ink screen display control device.
For example, after an image to be displayed, which needs to be displayed on an ink screen, is determined, a first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, wherein each first waveform sequence includes a plurality of driving frames corresponding to the corresponding image pixel point, and the plurality of driving frames in each first waveform sequence are ordered according to a set order. Optionally, a plurality of driving frames of image pixels on the image to be displayed can be determined according to an intermediate process required for changing the current color value of the screen pixel corresponding to the image pixel to the second color value of the image pixel, and 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 color changes correspond to different waveform sequences. The first color value may be understood as a color value (estimated color value) displayed by a screen pixel on the display screen of each screen pixel of the image to be displayed 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 an image pixel corresponding to the image to be displayed.
In a possible embodiment, the driving frame of each image pixel may be determined based on a preset waveform file (which may be provided in the form of a waveform file), that is, for a pixel on the image to be displayed, according to an intermediate process that needs to be passed from a current color value (a color value currently displayed by a screen pixel corresponding to an ink screen) to a second color value (a color value of an image pixel corresponding to the image 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, the driving frame includes a plurality of driving frames indicating to drive corresponding thin film transistors on the screen pixel corresponding to the ink screen, and the thin film transistors are sequentially driven according to different driving frames in the first waveform sequence, and the corresponding screen pixel will undergo the corresponding intermediate process and convert the currently displayed color value to the second color value.
In one possible embodiment, the first waveform sequence corresponding to each image pixel point in the image to be displayed may be a waveform sequence subjected to display acceleration processing, for example, the first waveform sequence is driven at a set frame output frequency of the thin film transistor matrix, where the frame output frequency is obtained by performing frequency boosting processing on an original output frequency (which may be provided by an ink screen manufacturer) of the thin film transistor matrix. In the related art, after the first waveform sequence corresponding to the 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. The thin film transistor matrix is controlled so that when the pixel points on the screen are converted from the current color value to the second color value, a plurality of intermediate processes can be experienced, 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 converting 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 drive frames to pass, a drive time of one drive frame is 20ms and a total drive time required is 200ms assuming that an original output frequency of the TFT is 50Hz, and the GC16 refresh mode of the ink screen supports display of 16-level gray requiring approximately 30 to 40 drive frames to pass from one gray level to another gray level, and a waveform sequence requires a total drive time of 600ms to 800ms. Due to the display principle of the electronic ink screen, the intermediate process required for updating the screen pixel point from one color to another color is more, and the required time is longer, so that the problems of low screen updating speed, low 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 that the display effect is reduced due to the fact that the output frequency is improved is compensated through a driving compensation mode, on the premise that the display effect is guaranteed, the image updating efficiency is effectively improved, and user experience is optimized. For example, the original output frequency may be up-converted according to a set up-conversion ratio (e.g., 1.1 to 2 times), for example, the up-conversion ratio is set to 2 times, when the original output frequency is 50Hz, the original processing speed for the driving frames is 50 frames per second, and the up-conversion processing for the original output frequency obtains a frame output frequency of 100Hz, then the processing speed for the driving frames at this time is increased to 100 frames per second, the driving time for one driving frame is increased from 20ms to 10ms, taking the A2 refresh mode as an example, the total driving time corresponding to the waveform sequence including 10 driving frames is shortened from 200ms to 100ms, taking the GC16 refresh mode as an example, the total driving time corresponding to the waveform sequence including 30 to 40 driving frames is shortened from 600ms to 800ms to 300ms to 400ms, and the screen update efficiency is obviously increased.
In one possible embodiment, the first waveform sequence corresponding to each image pixel point 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 point, and the plurality of key driving frames in each first waveform sequence are ordered according to the set order. In a possible embodiment, the key driving frame of each image pixel point may be determined based on preset key frame waveform data, and based on this, when determining the first waveform sequence corresponding to each image pixel point in the image to be displayed, 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 set 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 (a key frame waveform file that can be provided in the form of a waveform file) provided in this embodiment, a key driving frame corresponding to conversion between different color values (i.e., driving a color value on a screen pixel to another color value) is recorded. It can be understood that, according to the driving sequence, when the screen pixel points corresponding to the ink screen are sequentially driven according to the key driving frames (the thin film transistors corresponding to the screen pixel points can be driven by applying voltages corresponding to the key driving frames to the corresponding thin film transistors, for example, so that the pigment particles move 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. For example, after determining an image to be displayed that needs to be displayed on an ink screen, determining a current display image currently displayed on the ink screen, and 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 a driving sequence of each key driving frame in the same image pixel point. Further, a first waveform sequence corresponding to each image pixel point in the image to be displayed is determined based on one or more key driving frames corresponding to each image pixel point, and each first waveform sequence comprises one or more key driving frames which are sequentially ordered and used for realizing conversion of corresponding color values. In the related art, it is assumed that the frame output frequency of the display screen is 50Hz, that is, the driving time of one driving frame is 20ms, and it is assumed that the number of original driving frames corresponding to 4 original waveform sequences of an image to be displayed (including 4 image pixels) is determined to be 30 frames based on an original waveform file, and then the driving time for driving the ink screen to display the image to be displayed based on the original waveform sequences is 600ms. According to the scheme, the first waveform sequence composed of the key driving frames is determined, and on the assumption that the number of the key driving frames corresponding to 4 first waveform sequences of the image to be displayed is 15 frames, 16 frames and 18 frames respectively, after the first waveform sequences are subjected to frame supplementing alignment processing, the number of the driving frames corresponding to 4 second waveform sequences is 18 frames, so that 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 ink screen refreshing efficiency is obviously improved.
In a possible embodiment, the key frame waveform data provided by the present scheme records a key driving frame corresponding to a change from one color value to another color value of a screen pixel on an ink screen, where the key driving frame is determined based on a driving effect of each original driving frame in an original waveform file (which may be provided in the form of a waveform file) corresponding to the ink screen, and image pixel points in an image to be displayed correspond to screen pixel points on the ink screen one to one. The original waveform file can be provided by a supplier of the ink screen, namely, waveform sequences corresponding to conversion of different color values are defined in advance by the supplier and recorded in the original waveform file, and different waveform sequences comprise 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) matrix is directly controlled according to the control waveform sequence, and the Thin Film transistors are sequentially driven according to different original driving frames, so that the pigment particles in the microcapsules are moved to the designated position, and the image displayed by the ink screen is converted from the current display image to the image to be displayed. Because an ink screen manufacturer cannot predict the use scene of an ink screen, a predefined waveform sequence also contains non-key original drive frames besides the original drive frames playing a key role in image display, wherein the key original drive frames can be observed through experiments on the waveform sequences corresponding to different color value conversions, and whether the original drive frames can be used as key drive frames or not is determined according to the drive effect (namely the consistency degree of the converted color values and the predicted color values), namely the original drive frame with the most obvious drive effect can be determined as the key drive frame, and the original drive frame with the unobvious drive effect is the non-key drive frame. In addition, because 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 content and length of the waveform sequence actually required to be driven from the current color to the color to be updated of each screen pixel point on the ink screen are also different, but because the updating of the ink screen is a uniform process, in order to keep the updating time of all the image pixel points consistent, some invalid frames can be inserted into the short waveform sequence, so as to keep the driving time of all the waveform sequences consistent with the longest waveform sequence. Generally, the driving voltage indicated in the invalid frame is zero or a first set voltage value, and accordingly, when the screen pixel (tft) is driven based on the invalid frame, the color value of the corresponding screen pixel remains unchanged. Based on the method, the key driving frames, the non-key driving frames and the invalid driving frames in each waveform sequence can be determined by observing the driving effects of different waveform sequences and different original driving frames in the original waveform file, and the key frame waveform data of the scheme can be created based on the key driving frames. Optionally, the driving effects of different waveform sequences and different original driving frames in the original waveform file can be observed in different usage scenarios, the key driving frames, the non-key driving frames and the invalid driving frames in each waveform sequence in different usage scenarios are determined, and the key frame waveform data corresponding to different usage scenarios are created based on the key driving frames. When the first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, the corresponding key frame waveform data can be determined according to the current use scene, and then the key drive frame corresponding to each image pixel point in the image to be displayed is determined according to the determined key waveform file.
Through the mode of improving the output frequency of the thin film transistor matrix and/or screening the key driving frame, after the picture refreshing efficiency of the ink screen is improved, because the possibility that the picture display effect is reduced after acceleration exists, in order to guarantee the picture display effect, the first waveform sequence is driven and compensated according to the difference between the first color value and the second color value after being driven according to the first waveform sequence. Based on the method, after a first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, a first color value corresponding to each image pixel point is determined according to the first waveform sequence.
In a possible embodiment, the determination 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 relation can be recorded in the form of a mapping table or a mapping formula. The color value displayed after driving of one screen pixel point can be estimated according to the estimated color mapping relation, namely, for each image pixel point, the relation is determined according to the estimated color, and the corresponding first color value after driving the ink screen according to the first waveform sequence is determined under the current color value. In a possible embodiment, the estimated color mapping relationship may be established in advance according to a set frame output frequency, and after the ink screen is driven according to different waveform sequences (or drive frames) at different color values, color values corresponding to the pixel points are established.
S102: and determining a compensation frame of each image pixel point from the first color value to the corresponding second color value according to the first color value and the corresponding second color value of each image pixel point in the image to be displayed.
Illustratively, after determining a first color value corresponding to each image pixel point, for each image pixel point, a compensation frame from the first color value to a second color value of the corresponding image pixel point is determined according to the first color value and the second color value.
For example, when the tft matrix is driven by the first waveform sequence according to the frame output frequency of the tft matrix so that the ink screen displays an image to be displayed, the color difference between the first color value and the second color value of each pixel point of the screen is determined, and the 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 the first color value to the second color value or close to the second color value (relative to the second color value 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.
Illustratively, after the compensation frame corresponding to each image pixel point is determined, the compensation frame is used to perform driving compensation processing on the first waveform sequence corresponding to each image pixel point, so as to obtain a second waveform sequence corresponding to each image pixel point. At this time, the second waveform sequence includes the driving frames and the corresponding compensation frames 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 screen pixel when the ink screen is driven to display according to all driving frames in the first waveform sequence, and correspondingly, the compensation frame is added to the first waveform sequence when the driving compensation processing 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 corresponding to the modified drive frames-the first number corresponding to the replaced drive frames ≧ 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 driving the ink screen according to a first driving frame to a last but one number of previous driving frames in the first waveform sequence (for example, when five correction driving frames are set, two replaced driving frames correspond to the first color value corresponding to driving the ink screen according to a first driving frame to a last but one driving frame in the first waveform sequence, and when three correction driving frames are set, one replaced driving frame corresponds to the first color value corresponding to driving the ink screen according to a first driving frame to a last but one driving frame in the first waveform sequence). Correspondingly, when the drive compensation processing is performed on the first waveform sequence, the last first number of drive frames in the first waveform sequence is replaced by the second number of modified drive frames, for example, when 3 to 5 modified drive frames are set and the number of replaced original drive frames is two, when the drive compensation processing is performed on the first waveform sequence, the last two drive frames in the first waveform sequence are replaced by 3 to 5 modified drive frames.
S104: and driving an ink screen to display the image to be displayed based on the second waveform sequence.
Illustratively, after determining the second waveform sequences corresponding to the pixel points of the respective images, the ink screen is driven according to the second waveform sequences, so that the images displayed by the ink screen are converted from the currently displayed images to the images to be displayed. For each image pixel point, controlling the thin film transistor matrix based on the driving frame (including all or part of the driving frame and the compensation frame in the original first waveform sequence) in the corresponding second waveform sequence, namely controlling the thin film transistors based on the driving frame in the second waveform sequence in sequence, so that the corresponding screen pixel point realizes a corresponding color change intermediate process to drive the ink screen to display the image to be displayed.
In one possible embodiment, the ink screen display control method based on driving compensation further includes: responding to the image to be displayed as a final display image, and determining the current third color value of each screen pixel point of the ink screen; determining a third waveform sequence of each screen pixel point from the third color value to the corresponding second color value according to the third color value corresponding to each screen pixel point and the image to be displayed; and driving an ink screen to display the image to be displayed based on the third waveform sequence.
According to the ink screen display control method, in the process of displaying the middle display image (the image to be displayed is the middle 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 middle display image on the display screen is close to that of the image to be displayed. And 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 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 the image to be displayed.
Whether the image to be displayed is the final display image or not can be judged according to whether other images to be displayed waiting for being extracted and displayed exist in the image cache queue to be displayed or not, namely when other images to be displayed do not exist in the image cache queue to be displayed, the current image to be displayed can be determined to be the final display image. The method can also be used for timing after driving the ink screen to display the image to be displayed according to the second waveform sequence, and determining that the current image to be displayed is the final display image when the accumulated time for continuously displaying the image to be displayed reaches the set time length and other highlighting is not updated and displayed or a new image to be displayed is received. For example, when a video is displayed by using an ink screen, an image to be displayed in the video playing process is an intermediate display image (after the intermediate display image, a next frame of image to be displayed needs to be updated within a set time), and when the video playing is finished or paused, a corresponding image to be displayed is a final display image (the display content on the display screen does not need to be updated within the set time). It can be understood 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.
Illustratively, 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, the current third color value of each screen pixel point of the current ink screen is determined, according to the color difference between the third color value corresponding to each screen pixel point and the image to be displayed, the original waveform file is used for determining the third waveform sequence of each screen pixel point from the third color value to the corresponding second color value, and the ink screen is driven 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, and the display effect of the final display image is guaranteed.

If the screen refreshing speed 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 assuming that the number of the key driving frames corresponding to 4 first waveform sequences of the image to be displayed is 15 frames, 16 frames and 18 frames, respectively, the driving compensation processing is performed on the first waveform sequence by using a second number of correction driving frames (taking 3 correction driving frames to replace 2 key driving frames as an example), and at this time, the number of the driving frames corresponding to the second waveform sequence is 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 second waveform sequences are subjected to frame supplementing alignment processing, the number of the drive frames of the obtained 4 second waveform sequences is 19 frames (13 key drive frames +3 correction drive frames +3 invalid frames), 19 frames (14 key drive frames +3 correction drive frames +2 invalid frames), and 19 frames (16 key drive frames +3 correction drive frames), so that the drive time for driving the ink screen to display the image to be displayed based on the second waveform sequences is 380ms, and the refresh efficiency of the ink screen is obviously improved. If the frame refreshing speed of the ink screen is accelerated by increasing the output frequency of the thin film transistor matrix, assuming that 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, after determining that the number of the driving frames corresponding to 4 first waveform sequences of an image to be displayed (including 4 image pixels) is 30 frames based on the original waveform file, performing driving compensation processing on the first waveform sequences by using a second number of modified driving frames (taking 3 modified driving frames to replace 2 key driving frames as an example) to obtain a second waveform sequence, the number of the driving frames corresponding to 4 second waveform sequences is 31 frames, at this time, the driving time for driving the ink screen to display the image to be displayed is 310ms, and the refreshing efficiency of the ink screen is obviously improved.

Meanwhile, when the first waveform sequence is subjected to drive compensation, a second number of correction drive frames are determined according to the drive requirements of a first color value and a second color value corresponding to each image pixel point after the first original drive frame in the first waveform sequence of the first waveform sequence is driven to a last but one number of previous drive frames, and the first waveform sequence is subjected to drive compensation, so that the accuracy of the display image after the display acceleration is effectively ensured.

The determination of the compensation driving frame may be performed based on an original waveform file, that is, one or more driving frames corresponding to a first color value to a second color value are determined in the original waveform file, and the corresponding driving frame is used as the compensation driving frame, and the compensation driving frame may also be determined based on an estimated color mapping relationship, that is, one or more 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 frame is used as the compensation driving frame
S303: and adding one or more compensation driving frames corresponding to the compensation frames to the first waveform sequence of the corresponding image pixel points to obtain a second waveform sequence corresponding to each image pixel point.
Illustratively, for each image pixel point of an image to be displayed, the determined one or more compensation driving frames are added to the first waveform sequence of the corresponding image pixel point, so as to implement the driving compensation processing on the first waveform sequence. In one embodiment, the addition of one or more compensating drive frames to the first waveform sequence may be achieved by replacing invalid frames in the first waveform sequence. Based on this, when adding one or more compensation driving frames corresponding to the compensation frame to the first waveform sequence corresponding to the image pixel, the scheme includes: and replacing the invalid frame in the first waveform sequence of the corresponding image pixel point by using one or more compensation driving frames corresponding to the compensation frame.

For example, after the longest second waveform sequence is determined, an invalid frame is inserted into each second waveform sequence other than the longest second waveform sequence, so that the number of drive frames included in each second waveform sequence is consistent with the number of drive frames corresponding to the longest second waveform sequence (at this time, all the drive frames are key drive frames), and at this time, the sequence lengths of the second waveform sequences of other image pixels are aligned with the longest second waveform sequence.

If the frame refreshing speed of the ink screen is accelerated by improving 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, it is determined based on the original waveform file that the number of the driving frames corresponding to 4 first waveform sequences of an image to be displayed (including 4 image pixel points) is 30 frames, after the first waveform sequence is subjected to driving compensation processing by using the compensation driving frames to obtain a second waveform sequence, the number of the driving frames corresponding to 4 second waveform sequences is 31 frames, at this time, the driving time for driving the ink screen to display the image to be displayed is 310ms, and the refreshing efficiency of the ink screen is obviously improved.

When the picture refreshing speed of the ink screen is improved, the situation that the difference between the display color of the ink screen and the target color is too large is reduced and the picture display quality is ensured by the drive compensation of the first waveform sequence while the picture refreshing speed is improved. Meanwhile, when the first waveform sequence is driven and compensated, a compensation driving frame is determined according to the driving requirements of the first color value and the second color value corresponding to each image pixel point after the first waveform sequence is driven, the first waveform sequence is driven and compensated, and the accuracy of the displayed image after the display acceleration is effectively ensured.
