It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad 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. In addition, the order of the operations may be re-arranged. The above process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes described above may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a waveform sequence-based ink screen display control method provided in an embodiment of the present application, where the waveform sequence-based ink screen display control method provided in an embodiment of the present application may be executed by a waveform sequence-based ink screen display control device, and the waveform sequence-based ink screen display control device may be implemented by hardware and/or software and is integrated in a waveform sequence-based ink screen display control apparatus.
The following description will be given taking as an example an ink screen display control method in which the waveform sequence based ink screen display control apparatus executes a waveform sequence based ink screen display control method. Referring to fig. 1, the method for controlling the display of the ink screen based on the waveform sequence includes:
s101: determining a first waveform sequence corresponding to each image pixel point in an image to be displayed, wherein the first waveform sequence comprises one or more driving frames corresponding to the image pixel points, and the driving frames comprise effective driving frames and ineffective driving frames.
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 the image to be displayed according to the need by a processor in the ink screen display control device based on the waveform sequence.
Illustratively, 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 comprises a plurality of driving frames. Wherein the driving frames include active driving frames and inactive driving frames. Each first waveform sequence comprises a plurality of effective driving frames corresponding to the image pixel points, and the effective driving frames in each first waveform sequence are sequenced according to a set sequence. Optionally, a plurality of effective 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 (the color value of the image pixel corresponding to the image to be displayed), and different intermediate processes correspond to different effective 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 second color value can be understood as a color (target color value) of a pixel point of the image corresponding to the image to be displayed.
In one possible embodiment, the effective driving frame for each pixel of the image may be determined based on preset driving waveform data. Based on this, as shown in the first waveform sequence confirmation flowchart provided in fig. 2, when determining the first waveform sequence corresponding to each image pixel point in the image to be displayed, the method includes steps S1011 to S1012:
s1011: and determining a driving frame corresponding to each image pixel point in the image to be displayed according to the current display image and the pixel color updating content corresponding to the image to be displayed based on the set driving waveform data.
S1012: and determining a first waveform sequence corresponding to each image pixel point in the image to be displayed based on the driving frame.
In the driving waveform data (which may be provided in a waveform file, for example, an original waveform file of an ink screen) provided in this embodiment, a driving frame corresponding to conversion between different pixel color update contents (i.e., driving a color value on a pixel point of the screen to another color value) is recorded. It can be understood that, according to the driving sequence, when the screen pixels corresponding to the ink screen are sequentially driven according to the driving frames (the screen pixels can be driven by driving the thin film transistors corresponding to the screen pixels for a time period, for example, applying a voltage corresponding to the driving frames to the corresponding thin film transistors, so as to move the pigment particles to the designated positions), the screen pixels undergo an intermediate process of corresponding color change, and after the driving of one or more driving frames is sequentially completed, the screen pixels 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, determining pixel color update contents corresponding to the current display image and the image to be displayed, and determining one or more driving frames corresponding to each image pixel point in the image to be displayed under the pixel color update contents corresponding to the current display image and the image to be displayed based on a preset driving frame image waveform file, and a driving sequence of each 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 driving frames corresponding to each image pixel point, and each first waveform sequence comprises one or more sequentially ordered driving frames for realizing corresponding color value conversion.
The original waveform file of the ink screen 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 the different waveform sequences comprise a plurality of 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. Since the ink screen manufacturer cannot predict the usage scenario of the ink screen, the predefined waveform sequence includes, in addition to the valid driving frames that actually drive the image display, invalid driving frames that are not actually used for time alignment. The distinction between the valid drive frame and the invalid drive frame can be determined according to the drive voltage applied in the drive process, and the drive voltage reaching the set voltage threshold is the valid drive frame, otherwise the drive voltage is the invalid drive frame (the invalid drive frame is generally the drive frame with the voltage of 0, and is used for time alignment of the waveform sequence and does not drive the picture display). In addition, the effective driving frame can also be observed through experiments on waveform sequences corresponding to different color value conversions, and whether the original driving frame can be used as the effective driving frame or not is determined according to the driving effect (namely the consistency degree of the converted color value and the predicted color value), namely, the driving frame which plays a role in actually driving the display of the picture can be determined as the effective driving frame, and the driving frame which does not play a role in actually driving (for example, the driving frame with zero driving voltage) is the ineffective driving 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.
S102: and determining the longest effective sequence length in the effective sequence lengths corresponding to the first waveform sequences, wherein the effective sequence length of the first waveform sequence is determined based on the number of effective driving frames.
Illustratively, after determining the first waveform sequence corresponding to each image pixel point of the image to be displayed, determining the effective sequence length of each first waveform sequence. Wherein the sequence length of the first waveform sequence is determined based on the number of drive frames contained therein and the effective sequence length of the first waveform sequence is determined based on the number of effective drive frames, i.e. the effective sequence length of the first waveform sequence is proportional to the number of effective drive frames it contains or the effective sequence length can be identified by the number of effective drive frames it contains.
Further, after determining the effective sequence length of each first waveform sequence, the longest effective sequence length among the effective sequence lengths is determined. It is understood that the driving frame of the first waveform sequence corresponding to the longest valid sequence length may be composed of all valid driving frames, such as the first waveform sequence corresponding to the color value changing from black to white, or the first waveform sequence corresponding to the color value changing from white to black, or may be composed of valid driving frames and invalid driving frames, such as the valid driving frames corresponding to the color change when the color value changes between black and white, and the invalid driving frames added for alignment between different first waveform sequences.
S103: and deleting the invalid driving frame of each first waveform sequence based on the length of the longest valid sequence to obtain a second waveform sequence corresponding to each image pixel point.
Illustratively, after determining the longest valid sequence length in the valid sequence lengths corresponding to the respective first waveform sequences, taking the longest valid sequence length as a reference, performing invalid driving frame deletion processing on the respective first waveform sequences to obtain a second waveform sequence corresponding to each image pixel point. Here, the invalid driving frame deleting process may be understood as deleting a corresponding number (for example, a difference between an original sequence length and a longest valid sequence length) of invalid driving frames in the first waveform sequence, so that a sequence length of the first waveform sequence after deleting the invalid driving frames is aligned with the longest valid sequence length. It should be explained that, for the first waveform sequence corresponding to the longest valid sequence length, if its original sequence length is consistent with the longest valid sequence length (for example, the corresponding color change range is from black to white, or from white to black), the invalid driving frames do not need to be deleted from the first waveform sequence, and if the original sequence length is greater than the longest valid sequence length, all the invalid driving frames in the first waveform sequence are deleted.
In a possible embodiment, when performing the invalid drive frame deletion processing on each first waveform sequence based on the longest valid sequence length, the method specifically includes: and deleting invalid drive frames from each first waveform sequence based on the longest effective sequence length so as to align the sequence length of each first waveform sequence with the longest effective sequence length.
Illustratively, when the invalid driving frame deleting process is performed on the first waveform sequences, the number of invalid driving frames which need to be deleted for each first waveform sequence is determined according to the sequence length of each first waveform sequence (since the original waveform files need to synchronize the driving of the ink screens at the same time, the sequence length of each first waveform sequence is fixed under the same screen updating mode, for example, the sequence length of the A2 screen updating mode is fixed to 10 driving frames, and the sequence length of the GC16 screen updating mode is fixed to 30 driving frames). Further, according to the determined number of the invalid driving frames to be deleted, deleting a corresponding number of the invalid driving frames in each first waveform sequence, so that the sequence length of each first waveform sequence is aligned with the longest valid sequence length, and obtaining a second waveform sequence corresponding to each image pixel point, wherein the lengths of the second waveform sequences obtained after deleting the invalid driving frames are still consistent.
In a possible embodiment, after performing the invalid driving frame deletion processing on each first waveform sequence based on the longest valid sequence length, an invalid driving frame may be further inserted into the first waveform sequence to obtain a second waveform sequence corresponding to each image pixel point (in this case, the second waveform sequence includes the original valid driving frame and the inserted invalid driving frame).
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. And controlling the thin film transistor matrix based on the driving frame in the corresponding second waveform sequence for each image pixel point, namely sequentially controlling the thin film transistors based on the driving frame in the second waveform sequence, so that the corresponding screen pixel points realize a corresponding color change intermediate process to drive the ink screen to display the image to be displayed.
It can be understood that, 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 an 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. According to the scheme, effective driving frames in the first waveform sequence of the 4 image pixel points are determined to be 15 frames, 16 frames and 18 frames respectively according to set driving waveform data, correspondingly, invalid driving frames in the first waveform sequence of the 4 image pixel points are 15 frames, 14 frames and 12 frames respectively, and the length of the longest effective sequence is 18 effective driving frames. When the first waveform sequence is subjected to invalid driving frame deletion processing based on the longest valid sequence length, the number of invalid driving frames deleted by the first waveform sequence is 12 frames, and the sequence length of the corresponding second waveform sequence is 18 frames, wherein each second waveform sequence comprises the following driving frames: 3 inactive drive frames +15 active drive frames, 2 inactive drive frames +16 active drive frames, 18 active drive frames. At this time, the number of the driving frames corresponding to the 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 refresh efficiency of the ink screen is obviously improved.
The first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, the invalid driving frame deleting processing is performed on each first waveform sequence according to the longest valid sequence length in the first waveform sequence to obtain the second waveform sequence corresponding to each image pixel point, the ink screen is driven to display the image to be displayed based on the second waveform sequence, and the invalid driving frame deleting processing is performed on the longest valid sequence length, so that the sequence length of the obtained second waveform sequence is effectively reduced, the time consumed by the invalid driving frame when the ink screen is driven is reduced, the image updating speed of the ink screen is effectively improved, and the user experience is optimized.
On the basis of the foregoing embodiment, fig. 3 is a flowchart of another waveform sequence-based ink screen display control method provided in an embodiment of the present application, which is an embodiment of the waveform sequence-based ink screen display control method. Referring to fig. 3, the method for controlling the display of the ink screen based on the waveform sequence includes:
s201: and determining pixel color updating contents corresponding to each image pixel point in the image to be displayed according to the current display image and the image to be displayed.
For example, when an image to be displayed (which can be extracted from an image queue to be displayed) that needs to be updated and displayed on an ink screen is obtained, a second color value corresponding to each image pixel point in the image to be displayed is determined, a current color value corresponding to each screen pixel point in a current image (when a previous image to be displayed is displayed on the ink screen, the previous image to be displayed can be cached as the current image in a set cache location) of the ink screen is determined, and pixel color update content (that is, a change range corresponding to each image pixel point in the image to be displayed is determined according to the current color value to the second color value (for example, a change range corresponding to each image pixel point in the current image to the second color value is changed from black to white, from black to gray, and the like, and different color values can be represented by corresponding gray values).
Further, after determining the pixel color updating content corresponding to each image pixel point in the image to be displayed, comparing the pixel color updating content of each image pixel point with a set threshold range to judge whether the pixel color updating content of the corresponding image pixel point reaches the set threshold range, and determining the number of the image pixel points of which the pixel color updating content reaches the set threshold range.
Further, whether the number of image pixels of which the pixel color updating content reaches the set threshold range is within the set pixel number is determined. If the number of the image pixels of which the pixel color update content reaches the set threshold range is greater than the set number of the pixels, the method jumps to step S203, and the color change range of the image pixels does not need to be adjusted downward to ensure the image display effect. And if the number of the image pixel points of which the pixel color updating content reaches the set threshold range is less than or equal to the set pixel number, skipping to the step S202, and performing updating range down-regulation processing on the image pixel points of which the pixel color updating content reaches the set threshold range.
S202: and when the number of the image pixel points of which the pixel color updating contents reach the set threshold range is within the set pixel number, carrying out updating range down-regulation processing on the image pixel points of which the pixel color updating contents reach the set threshold range.
Illustratively, when it is determined that the number of image pixels whose pixel color update contents reach the set threshold range is within the set pixel number, the image pixels whose pixel color update contents reach the set threshold range are down-regulated to reduce the color change range of the corresponding image pixels. When the color change range of the image pixel points is adjusted downwards, when the first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, the color change range of the image pixel points of which the original pixel color updating content reaches the set threshold range is reduced, the number of the effective drive frames in the corresponding first waveform sequence is reduced, and similarly, the longest effective sequence length in the effective sequence lengths corresponding to the first waveform sequences is reduced, more ineffective drive frames can be deleted when the first waveform sequence is subjected to ineffective drive frame deletion processing, and the sequence length of the obtained second waveform sequence is shorter.
In a possible embodiment, the determination of whether the pixel color update content reaches the set threshold range according to the present scheme may be: when the pixel color updating content of the image pixel point is in a range from a first set color range to a second set color range or in a range from the second set color range to the first set color range, determining that the pixel color updating content of the image pixel point reaches a set threshold range, wherein the color value corresponding to the second set color range is higher than the color value corresponding to the first set color range.
For example, the minimum color value (gradation value) in the first set color range may be 0 to 10 (or other color values), the maximum color value (gradation value) in the second set color range may be 255, and the second set color range may be 245 (or other color values) to 255.
When determining whether the pixel color update content reaches the set threshold range, the pixel color update content may be determined based on a comparison of fixed color values of the first set color range and the second set color range, for example, a color corresponding to the first set color range is black, a corresponding first set color value (gray scale value) is 0, a color corresponding to the second set color range is white, and a corresponding second set color value (gray scale value) is 255. When the pixel color updating content of the image pixel point is from a first set color value to a second set color value, the pixel color updating content is considered to be from a first set color range to a second set color range, the pixel color updating content of the image pixel point is determined to reach a set threshold range, or when the pixel color updating content is from the second set color value to the first set color value, the pixel color updating content is considered to be from the second set color range to the first set color range, and the pixel color updating content of the image pixel point is determined to reach the set threshold range.
The comparison may be performed based on a fixed color value of a set color range and another set color range, for example, when a color corresponding to a first set color range is black and a color near the black color, a corresponding first set color value (gray scale value) is 0, a color value (gray scale value) corresponding to the first set color range is 0 to 10, a color corresponding to a second set color range is white and a color near the white color, a corresponding second set color value (gray scale value) is 255, a color value (gray scale value) corresponding to the second set color range is 245 to 255, when a pixel color update content of an image pixel is in a range from the first set color to the second set color range (for example, a range from a gray scale value of 0 to a color value of [245,255], the pixel color update content of the image pixel is determined to reach the set threshold range, or when the pixel color update content of the image pixel is determined to reach the set threshold range from the second set color to the first set color range (for example, a range from a gray scale value of [0,10 ]), the pixel color update content of the pixel color is determined to reach the set threshold range from the first set color.
Based on this, when this scheme carries out update scope down-regulation to the image pixel that pixel colour update content reaches the scope of settlement threshold value, include:
s2021: when the pixel color updating content of the image pixel point is in a range from a first set color range to a second set color range, updating the pixel color updating content of the image pixel point in a range from the first set color range to a third set color range, wherein the third set color range is lower than the second set color range; and/or the presence of a gas in the gas,
s2022: when the pixel color updating content of the image pixel point is from a second set color range to a first set color range, updating the corresponding pixel color updating content from the second set color range to a fourth set color range, wherein the fourth set color range is higher than the first set color range.
Illustratively, when determining to perform update range down-adjustment processing on image pixel points, different update range down-adjustment processing modes can be performed according to pixel color update contents in different directions.
When the pixel color update content of the image pixel is in a range from a first set color range to a second set color range (e.g., from black to white), the update range adjustment processing of the image pixel may be to update the pixel color update content of the image pixel in the range from the first set color range to a third set color range, where the third set color range is lower than the second set color range (e.g., to adjust the pixel color update content from black to white in the range from black to light white (gray value lower than 255)).
When the pixel color update content of the image pixel is in a range from the second set color range to the first set color range (e.g., from white to black), the update range down-adjustment processing on the image pixel may be to update the corresponding pixel color update content to be in a range from the second set color range to a fourth set color range, where the fourth set color range is higher than the first set color range (e.g., to change from white to black to dark gray (the gray value is higher than 0)). Wherein the third color setting range is higher than the fourth color setting range.
According to the scheme, when the number of the image pixel points with a large color change range is small, the update range down-regulation processing is carried out on the image pixel points with the pixel color update content reaching the set threshold range, and the image display quality is guaranteed while the image display speed is improved. For example, in the process of playing a video, when the number of image pixels with a large color change range is small (for example, only a few image pixels need to be changed from full black to full white, or from full white to full black, and correspondingly, the gray value is changed from 0 to 255, or from 255 to 0), under continuous picture refreshing, the color change range of the few pixels is reduced, the influence on the video playing and watching experience of a user is not large, but the fluency of the picture refreshing can be remarkably improved, and the user experience is effectively improved.

S204: and determining the longest effective sequence length in the effective sequence lengths corresponding to the first waveform sequences, wherein the effective sequence length of the first waveform sequence is determined based on the number of effective driving frames.
S205: and deleting the invalid driving frame of each first waveform sequence based on the length of the longest valid sequence to obtain a second waveform sequence corresponding to each image pixel point.
S206: and driving an ink screen to display the image to be displayed based on the second waveform sequence.
In a possible embodiment, the update range down-adjustment processing on the first waveform sequence may be performed in a dynamic update process of a picture to be displayed, and it may be detected whether the current update is an intermediate process of the dynamic update or a finally displayed static picture, and the update range down-adjustment processing mode is applied only in the intermediate process, otherwise, the original picture update mode is used to ensure the color accuracy of the final display, and the deletion processing mode may be performed in various picture update processes without affecting the color accuracy of the final display.
In one possible embodiment, in the step of determining a first waveform sequence corresponding to each image pixel point in the image to be displayed, if it is detected that the image to be displayed is a final display image, driving the ink screen to display the image to be displayed based on the first waveform sequence in response to the image to be displayed being the final display image. Namely, when the current display image is a static final display image, the ink screen can be directly driven to display the image to be displayed in the first waveform sequence, and the first waveform sequence does not need to be deleted or updated to ensure the final display quality.
For example, when it is determined that the image to be displayed is the final display image and the update range adjustment processing is performed on the image pixel points, the final display image may be compensated by using the optimized second waveform sequence, or the final display image may be compensated by using the first waveform sequence that is not optimized. When it is determined that the image to be displayed is the final display image and the update range of the image pixel points is adjusted, if the ink screen is not driven to display the image to be displayed based on the second waveform sequence, the third waveform sequence is directly determined according to the third color value (display color value) corresponding to each screen pixel point and the image to be displayed, and the ink screen is driven 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 that the image display speed is increased. If the ink screen is driven to display the image to be displayed based on the second waveform sequence, determining a third waveform sequence according to a corresponding third color value of each screen pixel point which is driven based on the second waveform sequence and the image to be displayed, and driving the ink screen to display the image to be displayed based on the third waveform sequence, so that the image display effect is ensured. In one possible embodiment, before driving the ink screen to drive the ink screen based on the second waveform sequence, whether each of the second waveform sequence or the third waveform sequence is aligned is determined, and if not, the second waveform sequence or the third waveform sequence is aligned by using an invalid frame, and then the ink screen is driven based on the aligned second waveform sequence or the aligned third waveform sequence.
In a possible embodiment, when it cannot be predicted in advance that a currently updated image to be displayed is an intermediate process image or a final display image, deletion processing and/or update range down-regulation processing may be performed on a first waveform sequence, and a corresponding third color value driven based on a second waveform sequence may be saved at the same time (where a current color value corresponding to each screen pixel point in a currently displayed image on an ink screen is a third color value after the saved down-regulation color range, and the third color value needs to be used as a starting color for next screen update), and then whether the updated image to be displayed is the intermediate process image or the final display image is checked again after a certain time delay, if the image to be displayed is the intermediate process image, no further processing is performed, and update processing of the next image to be displayed is continued, otherwise, compensation update is performed according to the saved third color value, so that an expected image is displayed.
Based on this, 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 detected to be the final display image, the current third color value of each screen pixel point of the ink screen is determined in response to the image to be displayed being the final display image; 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 waveform sequence-based ink screen display control method, when the image to be displayed is the final display image and the update range of the image pixel points is adjusted, 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 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. And when the image to be displayed is the final display image and the updating range reduction processing is not carried out on the image pixel points, the picture which is driven and displayed by the ink screen based on the second waveform sequence is consistent with the picture which is driven and displayed based on the first waveform sequence.
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 highlights are not updated and displayed or new images to be displayed are received. For example, when a video is displayed by using an ink screen, an intermediate image of an image to be displayed during the video playing process (after the intermediate image is displayed, a next image to be displayed needs to be updated within a set time) is displayed, 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 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.
For example, after the to-be-displayed image is displayed by driving the ink screen based on the second waveform sequence, if it is determined that the to-be-displayed image is the final display image, it is determined whether down-adjustment processing is performed on the display range (that is, it is determined whether update range down-adjustment processing is performed on image pixels whose pixel color update contents reach a set threshold range) is performed on the to-be-displayed image by driving the ink screen based on the second waveform sequence. If the display range is not down-regulated, the final display image does not need to be compensated. If the display range is down-regulated, the final display image needs to be compensated, namely the current third color value of each screen pixel point of the current ink screen is determined, a third waveform sequence from the third color value to the corresponding second color value of each screen pixel point is determined 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 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 and the updating range is adjusted, 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. The third waveform sequence may also be a sequence in which the invalid frame is deleted, and the color accuracy of the final display is not affected.
In one possible embodiment, the method for controlling the display of the ink screen based on the waveform sequence further includes: and under the condition that a compensation switch of the ink screen is turned on, determining that the image to be displayed is the final display image, and driving the ink screen to perform color compensation by using a third waveform sequence.
It should be explained that the compensation switch is used to control whether the ink screen needs to be driven by the third waveform sequence for color compensation.
The compensation switch comprises an on state and an off 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 under the condition that the on state of the compensation switch of the ink screen is on, namely, the current third color value of each screen pixel point of the ink screen is determined in response to the image to be displayed being the final display image, the third waveform sequence of each screen pixel point from the third color value to the corresponding second color value 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 compensation switch of the ink screen is closed, determining whether the image to be displayed is the final display image or not, and driving the ink screen to perform color compensation by utilizing the third waveform sequence. According to the scheme, the driving compensation of the first waveform sequence and/or the compensation starting time of the final display picture are flexibly controlled according to the on-off state of the first compensation switch and/or the compensation switch, so that the requirements of a user on the picture display quality and the picture display speed in different use scenes are met, and the use experience of the user is optimized.
In one possible embodiment, the amplitude threshold corresponding to the set threshold range and/or the updated range down-regulation processing provided by the present solution may be determined based on a preset threshold range and/or a down-regulation threshold set by a user, automatically regulated by a system, and/or defaulted. The initial values of the preset threshold range and the down-regulation threshold are default ranges and numerical values, and can be updated according to the adjustment operation of the preset threshold range and the down-regulation threshold by a user or the automatic adjustment operation of the system. The preset threshold range is used for determining the corresponding set threshold range when the pixel color updating content of the image pixel point is judged to reach the set threshold range, namely, the preset threshold range set by a user, automatically adjusted by a system or defaulted is used as the set threshold range. The down-regulation threshold is used for determining a threshold of range down-regulation when the update range down-regulation processing is performed on the image pixel point, namely, a user-set, system automatic adjustment or default down-regulation threshold is used as an amplitude threshold corresponding to the update range down-regulation processing. And adjusting the updating range of the image pixel points to be within the range threshold value.
The first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, the invalid driving frame deleting processing is performed on each first waveform sequence according to the longest valid sequence length in the first waveform sequence to obtain the second waveform sequence corresponding to each image pixel point, the ink screen is driven to display the image to be displayed based on the second waveform sequence, and the invalid driving frame deleting processing is performed on the longest valid sequence length, so that the sequence length of the obtained second waveform sequence is effectively reduced, the time consumed by the invalid driving frame when the ink screen is driven is reduced, the image updating speed of the ink screen is effectively improved, and the user experience is optimized. Meanwhile, when the number of image pixel points with a large color change range is small, the update range down-regulation processing is carried out on the image pixel points with the pixel color update content reaching the set threshold range, and the image display quality is ensured while the image display speed is improved.
