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.

Furthermore, the order of the operations may be rearranged.

The processes described above may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of an ink screen display control method based on a waveform sequence according to an embodiment of the present application, where the ink screen display control method based on a waveform sequence according to the embodiment of the present application may be executed by an ink screen display control device based on a waveform sequence, and the ink screen display control device based on a waveform sequence may be implemented by means of hardware and/or software and integrated in an ink screen display control device based on a waveform sequence.
The following description will be made taking, as an example, a method for executing the waveform sequence-based ink screen display control by the waveform sequence-based ink screen display control device. Referring to fig. 1, the ink screen display control method based on the waveform sequence includes:
s101: and determining a first waveform sequence corresponding to each image pixel point in the image to be displayed, wherein the first waveform sequence comprises one or more driving frames corresponding to the image pixel point, and the driving frames comprise effective driving frames and ineffective driving frames.
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 picture displayed by a processor in the ink screen display control device based on a waveform sequence according to needs.
After determining an image to be displayed on an ink screen, 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 drive frames include an active drive frame and an inactive drive frame. Each first waveform sequence comprises a plurality of effective driving frames corresponding to the corresponding image pixels, and the plurality of effective driving frames in each first waveform sequence are ordered according to a set order. Optionally, the plurality of effective driving frames of the image pixel point on the image to be displayed may be determined according to an intermediate process required by the current color value of the screen pixel point corresponding to the image pixel point to change to the second color value of the image pixel point (the color value of the image pixel point corresponding to the image to be displayed), where 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 waveform sequences correspond to different color changes. Wherein the second color value is understood as the color of the corresponding image pixel of the image to be displayed (target color value).
In one possible embodiment, the effective drive frame for each image pixel may be determined based on preset drive waveform data. Based on this, as shown in the first waveform sequence confirmation flow chart provided in fig. 2, the method includes steps S1011-S1012 when determining the first waveform sequence corresponding to each image pixel in the image to be displayed:
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 the form of a waveform file, for example, an original waveform file of an ink screen) provided in this embodiment, driving frames corresponding to the conversion between different pixel color update contents (i.e., driving one color value to another color value on a pixel point of a screen) are recorded, and optionally, the driving waveform data may also record a driving sequence between a plurality of driving frames converted between different pixel color update contents. It can be understood that when the screen pixel points corresponding to the ink screen are sequentially driven according to the driving frame according to the driving sequence (the screen pixel points can be driven by driving the thin film transistor corresponding to the screen pixel points for a time period, for example, applying the voltage corresponding to the driving frame to the corresponding thin film transistor so as to move the pigment particles to the designated position), the screen pixel points undergo an intermediate process of corresponding color change, and after one or more driving frames are sequentially completed, the screen pixel points will display the color corresponding to the second color value.
The method includes the steps of determining a current display image to be displayed on an ink screen after determining the image to be displayed on the ink screen, determining pixel color update contents corresponding to the current display image and the image to be displayed, 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 driving sequences of all 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 driving frames corresponding to each image pixel, and each first waveform sequence comprises one or more driving frames which are sequentially ordered and realize corresponding color value conversion.
The original waveform file of the ink screen can be provided by a supplier of the ink screen, that is, waveform sequences corresponding to conversion of different color values are defined by the supplier in advance 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, 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. Since the ink screen manufacturer cannot predict the usage scenario of the ink screen, the predefined waveform sequence includes not only valid driving frames that actually drive the image display, but also invalid driving frames that do time alignment and do not actually drive the image display. The distinction between the valid driving frame and the invalid driving frame can be determined according to the driving voltage applied in the driving process, and the driving voltage reaches the set voltage threshold, that is, the valid driving frame, or the invalid driving frame (the invalid driving frame is generally a driving frame with voltage of 0, which 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 obtained by performing experimental observation on waveform sequences corresponding to different color value conversion, and determining whether the original driving frame can be used as the effective driving frame according to the driving effect (i.e. the consistency degree of the converted color value and the predicted color value), i.e. the driving frame playing an actual driving role in displaying the picture can be determined as the effective driving frame, and the driving frame not playing an actual driving role (e.g. the driving frame with zero driving voltage) is the ineffective driving frame. 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.
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 sequences is determined based on the number of effective driving frames.
Illustratively, after determining the first waveform sequences corresponding to the image pixels of the image to be displayed, the effective sequence length of each first waveform sequence is determined. 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 contained therein, or the effective sequence length can be identified by the number of effective drive frames contained therein.
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 will be appreciated that the drive frames of the first waveform sequences corresponding to the longest valid sequence length may be composed entirely of valid drive frames, such as the first waveform sequences corresponding to the color value changing from black to white, or from white to black, or may be composed of valid drive frames and invalid drive frames, such as the valid drive frames driving the corresponding color change when the color value changes between black and white, and the invalid drive frames added for alignment between different first waveform sequences.
S103: and performing invalid driving frame deletion processing on each first waveform sequence based on the longest valid sequence length to obtain a second waveform sequence corresponding to each image pixel point.
After determining the longest valid sequence length in the valid sequence lengths corresponding to the first waveform sequences, performing invalid driving frame deletion processing on the first waveform sequences with the longest valid sequence length as a reference, so as to obtain a second waveform sequence corresponding to each image pixel point. Here, the invalid driving frame deletion process may be understood as deleting a corresponding number of invalid driving frames (e.g., a difference between an original sequence length and a longest valid sequence length) in the first waveform sequence, such that the sequence length of the first waveform sequence after deletion of the invalid driving frame 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 the 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 at this time, 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 one possible embodiment, when performing the invalid driving frame deletion processing on each of the first waveform sequences based on the longest valid sequence length, the method specifically includes: and deleting an invalid driving frame from each of the first waveform sequences based on the longest valid sequence length so as to align the sequence length of each of the first waveform sequences with the longest valid sequence length.
For example, when the invalid driving frame deletion process is performed on the first waveform sequences, the number of invalid driving frames to be deleted for each first waveform sequence is determined according to the sequence length of each first waveform sequence (since the original waveform file needs to synchronize driving of the ink screen uniformly, in the same screen update mode, the sequence length of each first waveform sequence is fixed, for example, the sequence length of the A2 screen update mode is fixed to 10 driving frames, and the sequence length of the GC16 screen update mode is fixed to 30 driving frames). Further, according to the determined number of invalid driving frames to be deleted, deleting a corresponding number of invalid driving frames from each first waveform sequence, so that the sequence length of each first waveform sequence is aligned with the longest valid sequence length, obtaining second waveform sequences corresponding to each image pixel point, and keeping the lengths of the second waveform sequences obtained after deleting the invalid driving frames consistent.
In one possible embodiment, after performing the ineffective driving frame deletion process on each first waveform sequence based on the longest effective sequence length, an ineffective driving frame may be further inserted into the first waveform sequence, so as to obtain a second waveform sequence corresponding to each image pixel point (where the second waveform sequence includes the original effective driving frame and the inserted ineffective driving frame).
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. The method comprises the steps of controlling a thin film transistor matrix based on a driving frame in a corresponding second waveform sequence for each image pixel point, namely controlling the thin film transistor 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, and the ink screen is driven to display an image to be displayed.
It is 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 for determining an image to be displayed (including 4 image pixels) 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 method determines that effective driving frames in a first waveform sequence of the 4 image pixel points are respectively 15 frames, 16 frames and 18 frames according to the set driving waveform data, and corresponding ineffective driving frames in the first waveform sequence of the 4 image pixel points are respectively 15 frames, 14 frames and 12 frames, wherein the length of the longest effective sequence is 18 frames of 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, the sequence length of the corresponding second waveform sequence is 18 frames, and each second waveform sequence comprises driving frames as follows: 3 invalid driving frames+15 valid driving frames, 2 invalid driving frames+16 valid driving frames, 18 valid driving frames. At this time, the number of 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 refreshing efficiency of the ink screen is obviously improved.
According to the method, the first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, invalid driving frame deletion processing is conducted on each first waveform sequence according to the longest effective sequence length in the first waveform sequence, a second waveform sequence corresponding to each image pixel point is obtained, the ink screen is driven to display the image to be displayed based on the second waveform sequence, invalid driving frame deletion processing is conducted on the longest effective sequence length, the sequence length of the obtained second waveform sequence is effectively reduced, time consumed by invalid driving frames when the ink screen is driven is reduced, the updating speed of the ink screen picture is effectively improved, and user experience is optimized.
On the basis of the above embodiments, fig. 3 shows a flowchart of another waveform sequence-based ink screen display control method according to the embodiment of the present application, where the waveform sequence-based ink screen display control method is implemented by the above waveform sequence-based ink screen display control method. Referring to fig. 3, the ink screen display control method 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 may be extracted from an image queue to be displayed) to be displayed on an ink screen is obtained, a second color value corresponding to each image pixel in the image to be displayed is determined, a current color value corresponding to each screen pixel in a current image to be displayed on the ink screen (when a previous image to be displayed is displayed on the ink screen, the previous image to be displayed may be cached as the current image to be displayed in a set cache position) is determined, and a pixel color update content corresponding to each image pixel in the image to be displayed (i.e., a change range from the current color value to the second color value, for example, a change from black to white, a change from black to gray, etc., is determined according to the current color value to the second color value, and different color values may be represented by corresponding gray values).
Further, after determining the pixel color update content corresponding to each image pixel point in the image to be displayed, comparing the pixel color update content of each image pixel point with the set threshold range to determine whether the pixel color update content of the corresponding image pixel point reaches the set threshold range, and determining the number of image pixel points in which the pixel color update content reaches the set threshold range.
Further, it is determined whether the number of image pixels for which the pixel color update content reaches the set threshold range is within the set number of pixels. If the number of image pixels whose pixel color update content reaches the set threshold range is greater than the set number of pixels, the process goes to step S203, where the color change range of the image pixels is not required to be adjusted down, so as to ensure the image display effect. If the number of the image pixels whose pixel color update content reaches the set threshold range is less than or equal to the set pixel number, the process goes to step S202, where the update range is adjusted down for the image pixels whose pixel color update content reaches the set threshold range.
S202: and when the number of the image pixels with the pixel color updated contents reaching the set threshold range is within the set pixel number, performing updating range down-regulating processing on the image pixels with the pixel color updated contents reaching the set threshold range.
For example, when it is determined that the number of image pixels whose pixel color update contents reach the set threshold range is within the set number of pixels, the image pixels whose pixel color update contents reach the set threshold range are processed down to reduce the color variation range of the corresponding image pixels. When the color change range of the image pixel points is adjusted downwards, and the first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, as the color change range of the image pixel points, of which the original pixel color update content reaches the set threshold range, is reduced, the number of effective driving frames in the corresponding first waveform sequences is reduced, and likewise, the length of the longest effective sequence in the effective sequence length corresponding to each first waveform sequence is also reduced, more ineffective driving frames can be deleted when the ineffective driving frame deletion processing is carried out on the first waveform sequences, and the sequence length of the obtained second waveform sequences is shorter.
In one 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 points is from a first set color range to a second set color range or from the second set color range to the first set color range, determining that the pixel color updating content of the image pixel points reaches a set threshold range, wherein a color value corresponding to the second set color range is higher than a color value corresponding to the first set color range.
For example, the smallest color value (gradation value) in the first set color range is 0, the first set color range may be 0 to 10 (other color values may be used), the largest color value (gradation value) in the second set color range is 255, and the second set color range may be 245 (other color values may be used) to 255.
When determining whether the pixel color update content reaches the set threshold range, it may be performed based on a comparison of fixed color values of the first set color range and the second set color range, for example, the color corresponding to the first set color range is black, the corresponding first set color value (gray value) is 0, the color corresponding to the second set color range is white, and the corresponding second set color value (gray value) is 255. When the pixel color updating content of the image pixel point is from the first set color value to the second set color value, the pixel color updating content is considered to be from the first set color range to the second set color range, and the pixel color updating content of the image pixel point is determined to reach the set threshold range, or when the pixel color updating content is considered to be from the second set color range to the first set color range, the pixel color updating content of the image pixel point is determined to reach the set threshold range.
The image processing may be performed based on a comparison of fixed color values of the set color range and another set color range, for example, when the color corresponding to the first set color range is black and a color in the vicinity thereof, the corresponding first set color value (gradation value) is 0, the corresponding color value (gradation value) of the first set color range is 0 to 10, the corresponding color of the second set color range is white and a color in the vicinity thereof, the corresponding second set color value (gradation value) is 255, the corresponding color value (gradation value) of the second set color range is 245 to 255, and when the pixel color update content of the image pixel point is a range from the first set color value to the second set color range (for example, a range from 0 to [245,255], the pixel color update content is regarded as a range from the first set color to the second set color range, the pixel color update content of the image pixel point is determined to reach the set threshold range, or when the pixel color update content of the second set color range is regarded as a range from the second set color value to the first set color range (for example, the range from 255 to [0,10 ]).
Based on this, when the update range down-adjustment processing is performed on the image pixel points whose pixel color update contents reach the set threshold range, the method includes:
s2021: when the pixel color updating content of the image pixel point is from a first set color range to a second set color range, updating the pixel color updating content of the image pixel point 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 number of the groups of groups,
s2022: and when the pixel color updating content of the image pixel points is from the second set color range to the first set color range, updating the corresponding pixel color updating content from the second set color range to the fourth set color range, wherein the fourth set color range is higher than the first set color range.
For example, when determining to perform the update range downregulation processing on the image pixel points, different update range downregulation processing modes can be performed according to the pixel color update contents in different directions.
When the pixel color update content of the image pixel point is changed from the first set color range to the second set color range (for example, changed from black to white), the update range down-adjustment processing for the image pixel point may be performed by updating the pixel color update content of the image pixel point from the first set color range to a third set color range, which is lower than the second set color range (for example, changed from black to white down-adjusted from black to light white (gray value is lower than 255)).
When the pixel color update contents of the image pixel point are changed from the second set color range to the first set color range (for example, from white to black), the update range down-adjustment processing of the image pixel point may be performed by updating the corresponding pixel color update contents from the second set color range to a fourth set color range, which is higher than the first set color range (for example, by changing from white to black down to black to dark gray (gray value is higher than 0)). Wherein the third set color range is higher than the fourth set color range.
When the number of the image pixel points with larger color change range is small, the image pixel points with the pixel color update content reaching the set threshold range are subjected to update range down-regulation processing, so that the picture display speed is improved, and the picture display quality is ensured. For example, in the video playing process, when the number of image pixels with a larger color variation 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 the corresponding gray value is changed from 0 to 255, or from 255 to 0), the color variation range of the few pixels is reduced under continuous picture refreshing, so that the influence on the video playing and watching experience of a user is small, but the smoothness of the picture refreshing can be remarkably improved, and the user experience is effectively improved.
S203: and determining a first waveform sequence corresponding to each image pixel point in the image to be displayed, wherein the first waveform sequence comprises one or more driving frames corresponding to the image pixel point, and the driving frames comprise effective driving frames and ineffective driving frames.
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 sequences is determined based on the number of effective driving frames.
S205: and performing invalid driving frame deletion processing on each first waveform sequence based on the longest valid sequence length to obtain a second waveform sequence corresponding to each image pixel point.
S206: and driving the ink screen to display the image to be displayed based on the second waveform sequence.
In one possible embodiment, the update range down-adjustment processing of the first waveform sequence may be performed during a dynamic update process of a frame to be displayed, it may be detected whether the current update is an intermediate process of the dynamic update or a final displayed static frame, and only the intermediate process applies the update range down-adjustment processing mode, otherwise, the original frame update mode is used to ensure the color accuracy of the final display, and the deletion processing mode may be performed during various frame update processes, and does not affect the color accuracy of the final display.
In one possible embodiment, in determining a first waveform sequence corresponding to each image pixel point in the image to be displayed, if the image to be displayed is detected to be the final display image, the ink screen is driven 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. 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 on the first waveform sequence, and deletion processing or updating range down-regulating processing is not needed for the first waveform sequence, so that the final display quality is ensured.
For example, when the image to be displayed is determined to be the final display image and the updating range of the pixel points of the image is subjected to the down-regulating processing, the final display image can be compensated based on the optimized second waveform sequence, or the final display image can be compensated by using the first waveform sequence which is not optimized. When the image to be displayed is determined to be the final display image and the updating range of the image pixel points is subjected to the down-regulating processing, if the ink screen is not driven to display the image to be displayed based on the second waveform sequence at the moment, 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, so that the image to be displayed does not need to be displayed based on the second waveform sequence first, and 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 third color value and the image to be displayed, which correspond to each screen pixel point after being driven based on the second waveform sequence, and driving the ink screen to display the image to be displayed based on the third waveform sequence, so that the picture display effect is ensured. In one possible embodiment, before driving the ink screen based on the second waveform sequence, determining whether each of the second waveform sequence or the third waveform sequence is aligned, if not, using the invalid frame to align the second waveform sequence or the third waveform sequence, and then driving the ink screen based on the aligned second waveform sequence or third waveform sequence.
In one possible embodiment, when it is not known in advance whether the currently updated image to be displayed is an intermediate process image or a final display image, deletion processing and/or update range down-adjustment processing may be performed on the first waveform sequence first, while corresponding third color values driven based on the second waveform sequence are stored (where the current color value corresponding to each screen pixel point in the currently displayed image of the ink screen is a third color value after the stored down-adjustment color range, and the next screen update needs to use the third color value as a starting color), and then a certain time is delayed to check again whether the currently updated image to be displayed is an intermediate process image or a final display image, if the currently updated image to be displayed is an 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 stored third color value, so that the expected image is displayed.
Based on the above, 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 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.
According to the waveform sequence-based ink screen display control method, when the image to be displayed is the final display image and the updating range of the image pixel points is subjected to the down-regulating treatment, 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, after the ink screen is driven according to the second waveform sequence, 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, 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 of the image pixel points is not subjected to the down-regulating processing, 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 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 a video, an intermediate image of an image to be displayed in the video playing process (after the intermediate image is displayed, the next frame of the 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.
For example, after the ink screen is driven to display the image to be displayed based on the second waveform sequence, if it is determined that the image to be displayed is the final display image, it is determined whether the display range is subjected to the down-adjustment processing (that is, whether there is an image pixel point in which the pixel color update content reaches the set threshold range is subjected to the update range down-adjustment processing) when the ink screen is driven to display the image to be displayed based on the second waveform sequence. If the display range is not subjected to the down-regulation processing, the final display image does not need to be subjected to the compensation processing. If the display range is subjected to down-regulation processing, compensation processing is required to be performed on the final display image, namely, a 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 utilizing an 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 subjected to the down-regulating treatment, 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. The third waveform sequence may be a sequence after deleting the invalid frame, and does not affect the color accuracy of the final display.
In one possible embodiment, the ink screen display control method based on the waveform sequence provided by the scheme further includes: and under the condition that a 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 compensation switch is used to control whether the ink screen needs to be driven with the third waveform sequence for color compensation.
When the on-off state of the compensation switch of the ink screen is on, and the image to be displayed is determined to be the final display image, the ink screen is driven to perform color compensation by using a third waveform sequence, 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, and the third waveform sequence from the third color value to the third waveform sequence corresponding to the 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 the image to be displayed is driven to be displayed by the ink screen 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 is not needed, and driving the ink screen to perform color compensation by using the third waveform sequence is also not needed. According to the scheme, the first waveform sequence is flexibly controlled to be driven and compensated and/or the compensation starting time of the final display picture is flexibly controlled according to the switching state of the first compensation switch and/or the switching state of the compensation switch, 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 set threshold range and/or the update range down-regulation processing corresponding amplitude threshold provided by the scheme can be determined based on a user setting, a system automatic adjustment and/or a default preset threshold range and/or a down-regulation threshold. The initial values of the preset threshold range and the down-regulating threshold are default ranges and numerical values, and the initial values can be updated according to the adjustment operation of the user on the preset threshold range and the down-regulating threshold or the adjustment operation automatically performed by the system. The preset threshold range is used for determining a corresponding set threshold range when judging whether the pixel color updating content of the image pixel points reaches 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-regulating threshold is used for determining a down-regulating threshold of the range when the updating range down-regulating process is carried out on the image pixel points, namely, the down-regulating threshold set by a user, automatically regulated by a system or defaulted is used as a corresponding amplitude threshold of the updating range down-regulating process. The amplitude corresponding to the updating range down-regulation processing of the image pixel points is within an amplitude threshold.
According to the method, the first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, invalid driving frame deletion processing is conducted on each first waveform sequence according to the longest effective sequence length in the first waveform sequence, a second waveform sequence corresponding to each image pixel point is obtained, the ink screen is driven to display the image to be displayed based on the second waveform sequence, invalid driving frame deletion processing is conducted on the longest effective sequence length, the sequence length of the obtained second waveform sequence is effectively reduced, time consumed by invalid driving frames when the ink screen is driven is reduced, the updating speed of the ink screen picture is effectively improved, and user experience is optimized. And meanwhile, when the number of the image pixels with larger color change range is smaller, the image pixels with the pixel color updated content reaching the set threshold range are subjected to updating range down-regulation processing, so that the picture display speed is improved, and meanwhile, the picture display quality is ensured.
