Detailed Description
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 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 relevant portions of 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 process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of an ink screen display control method according to an embodiment of the present disclosure, where the ink screen display control method according to the embodiment of the present disclosure may be executed by an ink screen display control device, and the ink screen display control device may be implemented by hardware and/or software and integrated in an ink screen display control apparatus.
The following description will be given taking an example in which the ink screen display control device executes the ink screen display control method. Referring to fig. 1, the ink screen display control method 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 key driving frames corresponding to the image pixel point.
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 by the processor in the ink screen display control device according to the need.
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 one or more key frames. Each first waveform sequence comprises a plurality of key driving frames corresponding to the image pixel points, and the key driving frames in each first waveform sequence are sequenced according to a set sequence. Optionally, a plurality of key 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 key 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 key drive frame for each image pixel may be determined based on pre-defined key frame waveform data. Based on this, 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 key driving frame corresponding to each image pixel point in the image to be displayed according to the current display image and the image to be displayed based on the set key frame waveform data.
S1012: and determining a first waveform sequence corresponding to each image pixel point in the image to be displayed based on the key driving frame.
In the key frame waveform data (which may 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, and optionally, the key frame waveform data may further record a driving sequence between a plurality of key driving frames for conversion between different colors. 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.
Illustratively, after an image to be displayed which needs to be displayed on an ink screen is determined, a current display image which is currently displayed on the ink screen is determined, 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 are determined based on preset key frame image waveform data, and the driving sequence of each key driving frame in the same image pixel point is determined.
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 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 a non-critical original drive frame besides an original drive frame playing a key role in image display, wherein the critical original drive frame can be experimentally observed through converting waveform sequences corresponding to different color values, and whether the original drive frame can be used as a key drive frame or not is determined according to a 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-critical 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 the 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 ink screen updating 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 scheme, the driving effects of different waveform sequences and different original driving frames in the original waveform file are observed, the key driving frame, the non-key driving frame and the invalid driving frame in each waveform sequence are determined, and the key frame waveform data of the scheme are 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 frame, the non-key driving frame and the invalid driving frame 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 frame. 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.
S102: and performing frame supplementing alignment processing on the first waveform sequence to obtain a second waveform sequence corresponding to each image pixel point in the image to be displayed.
Exemplarily, after a first waveform sequence corresponding to each image pixel point is determined, because the ink screen updating is a uniform process, in order to keep the updating time of all image pixel points consistent, the determined first waveform sequence corresponding to each image pixel point is subjected to frame supplementing alignment processing, that is, a driving frame (generally, an invalid frame indicating that a driving voltage is zero or below a set value) which does not affect a color value after driving a screen pixel point is inserted into a part of the first waveform sequence, so that the number of the driving frames included in each first waveform sequence is consistent, and a second waveform sequence corresponding to each image pixel point in an image to be displayed is obtained.
It is understood that the sequence length of each second waveform sequence or the number of drive frames included after the complementary frame alignment process is performed is the same. For example, assuming that the number of key driving frames corresponding to 4 first waveform sequences of an image to be displayed is 15 frames, 16 frames, and 18 frames, respectively, after performing frame complementing alignment processing on these first waveform sequences, the number of driving frames corresponding to 4 second waveform sequences obtained is 18 frames or more than 18 frames.
S103: 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 the key driving frame and the inserted driving frame) in the corresponding second waveform sequence, 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 the 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, 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 key 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 one possible embodiment, the ink screen display control method provided by the present disclosure 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 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 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 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.
In a possible embodiment, when it is determined that the image to be displayed is the final display image, if the ink screen is not driven to display the image to be displayed based on the second waveform sequence at this time, the third waveform sequence is directly determined according to 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 without displaying the image to be displayed based on the second waveform sequence first, so that the image display speed is increased. In one possible embodiment, before driving the ink screen to drive the ink screen based on the second waveform sequence, it is determined whether each of the second waveform sequences is aligned, and if not, the ink screen is driven based on the aligned second waveform sequence after the second waveform sequences are aligned by using the invalid frame.
The first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, the first waveform sequence is subjected to frame supplementing alignment processing to obtain a second waveform sequence, the ink screen is driven to display the image to be displayed based on the second waveform sequence, the second waveform is obtained by performing frame supplementing alignment processing on the first waveform sequence formed by a plurality of key driving frames, time consumed by non-key frames or invalid frames when the ink screen is driven is reduced, the ink screen refreshing speed is improved, the second waveform sequences of the image pixel points are aligned by performing frame supplementing alignment processing on the first waveform sequence, normal driving of the ink screen is guaranteed, and image display quality is guaranteed.
On the basis of the foregoing embodiment, fig. 2 is a flowchart of another ink screen display control method provided in an embodiment of the present application, which is an embodiment of the ink screen display control method. Referring to fig. 2, the ink screen display control method includes:
s201: 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 key driving frames corresponding to the image pixel point.
S202: and determining a first color value corresponding to driving of the ink screen by each image pixel point based on the corresponding first waveform sequence.
It should be explained that, after the first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, since only the key driving frame with an obvious driving effect is reserved in the first waveform sequence and the non-key driving frame with an unobvious driving effect is removed, there may be a situation that the display effect is reduced due to insufficient driving on the ink screen (or screen pixel points). In order to ensure the display effect after the ink screen is driven according to the compensation frame on the second waveform sequence behind the ink screen, the scheme also carries out driving compensation on the first waveform sequence according to the color difference between the first color value and the second color value which are driven by the key driving frame, and then carries out frame compensation alignment processing on the first waveform sequence after the driving compensation.
Illustratively, for each image pixel of the image to be displayed, determining a corresponding first color value of each image pixel for driving the ink screen (or screen pixel) based on the corresponding first waveform sequence. The first color value can be understood as a color value (estimated color value) displayed by each screen pixel point of the image to be displayed on the screen pixel point of the display screen when the ink screen is driven to display according to the first waveform sequence.
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 corresponding to a pixel point after the pixel point is screen-driven according to different waveform sequences (or driving frames) at different color values. 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 one possible embodiment, the pre-estimated color mapping relationship may be established based on color values corresponding to pixel points of the ink screen after the ink screen is driven according to different waveform sequences (or driving frames) under different color values.
S203: and performing drive compensation processing on the first waveform sequence corresponding to each image pixel point according to the first color value and the second color value corresponding to each image pixel point in the image to be displayed.
Exemplarily, after a first color value corresponding to each image pixel point is determined, a second color value corresponding to each image pixel point of the image to be displayed is determined, a driving compensation mode for the first waveform sequence is further determined according to the first color value of each image pixel point and the corresponding second color value, and the driving compensation processing is performed on the first waveform sequence corresponding to each image pixel point according to the corresponding driving compensation mode.
In a possible embodiment, when performing drive compensation processing on a first waveform sequence corresponding to each image pixel point according to the first color value and a second color value corresponding to each image pixel point in the image to be displayed, the method includes steps S2031 to S2032:
s2031: and determining a driving compensation parameter of an image pixel point from the first color value to the second color value according to the first color value and the second color value corresponding to the image to be displayed.
S2032: and performing drive compensation processing on the first waveform sequence corresponding to each image pixel point by using the drive compensation parameters.
Exemplarily, after determining a first color value corresponding to each image pixel point, determining a second color value corresponding to each image pixel point in the image to be displayed, and further determining a driving compensation parameter of each image pixel point of the image to be displayed according to the first color value and the corresponding second color value of each image pixel point. Furthermore, after determining the driving compensation parameters of each image pixel point, the driving compensation parameters are used to perform driving compensation processing on the first waveform sequence corresponding to each image pixel point, so that after the driving processing is performed on the screen pixel point according to the driving frame in the first waveform sequence, the displayed color value is consistent with the second color value corresponding to the image pixel point.
In one possible embodiment, the drive compensation parameter may be one or more compensation drive frames for addition to the first waveform sequence and may also be a second number of modified drive frames (the second number of modified drive frames being understood to be at least two modified drive frames) for replacing the last first number of key drive frames of the first waveform sequence. The second number of the correction drive frames for replacing the key drive frames is greater than the first number of the replaced key drive frames (the second number corresponding to the correction drive frames-the first number corresponding to the replaced key drive frames is greater than or equal to 1).
Correspondingly, when the driving compensation parameter is the compensation driving frame, the method specifically comprises the following steps of determining a first color value corresponding to each image pixel point when each image pixel point drives the ink screen based on the corresponding first waveform sequence: and determining a first color value corresponding to the ink screen driven by each image pixel point of the image to be displayed based on all key driving frames in the corresponding first waveform sequence. According to the scheme, when the driving compensation parameter from the first color value to the second color value of an image pixel point is determined according to the first color value and the second color value corresponding to the image to be displayed, the method specifically comprises the following steps: and determining one or more compensation driving frames of each image pixel point of the image to be displayed according to the first color value and the second color value corresponding to each image pixel point in the image to be displayed. Correspondingly, when the driving compensation parameters are used for performing driving compensation processing on the first waveform sequence corresponding to each image pixel point, the method specifically comprises the following steps: and adding one or more compensation driving frames corresponding to the driving compensation parameters to the first waveform sequence corresponding to the image pixel points.
For example, after determining a first waveform sequence corresponding to each image pixel point of an image to be displayed, after further determining that each image pixel point in the image to be displayed drives an ink screen based on all key driving frames in the corresponding first waveform sequence, determining a first color value corresponding to a screen pixel point on the ink screen after driving the ink screen according to a first key driving frame to a last key driving frame in the first waveform sequence at a current color value according to an estimated color determination relationship for each image pixel point, for example. Furthermore, for each image pixel point of the image to be displayed, according to the first color value and the corresponding second color value, one or more compensation driving frames from the corresponding first color value to the corresponding second color value of each image pixel point in the image to be displayed are determined. The compensation driving frame may be determined 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 frames are used as compensation driving frames. Furthermore, for each image pixel point of the image to be displayed, the determined one or more compensation driving frames are substituted for the invalid frame in the first waveform sequence of the corresponding image pixel point, so that the driving compensation processing of the first waveform sequence is realized. At this time, the driving frames in the first waveform sequence after the driving compensation process include one or more compensation driving frames replacing the invalid frames, in addition to a part of the driving frames (including all valid frames (key driving frames) and the invalid frames except for being replaced) in the original first waveform sequence. Alternatively, one or more compensation drive frames may be added directly to the first waveform sequence (e.g., at the end of the first waveform sequence). The driving frames in the first waveform sequence after the driving compensation process at this time include one or more compensation driving frames inserted in the first waveform sequence (e.g., at the end of the first waveform sequence) in addition to all driving frames in the original first waveform sequence.
When the driving compensation parameter is the correction driving frame, the method specifically comprises the following steps of determining a first color value corresponding to driving of the ink screen by each image pixel point based on the corresponding first waveform sequence: determining a first number corresponding to a key drive frame to be replaced in a first waveform sequence corresponding to each image pixel point of the image to be displayed; and determining a first color value corresponding to driving the ink screen according to the first key driving frame to the last key driving frame in the first waveform sequence corresponding to each image pixel point of the image to be displayed. Wherein the second number of modified drive frames used to replace the key drive frames is greater than the first number of key drive frames being replaced.
Exemplarily, after determining the first waveform sequence corresponding to each image pixel point corresponding to the image to be displayed, further determining key driving frames to be replaced in the first waveform sequence corresponding to each image pixel point of the image to be displayed, and a first number corresponding to the key driving frames to be replaced. The first number corresponding to the key driving frames to be replaced may be a default number, a number set by a user, and a dynamic number obtained by adaptive adjustment of the system.
For example, when two correction drive frames are set, and one replaced key drive frame corresponds to a first color value after the ink screen is driven according to a first key drive frame to a second last key drive frame in the first waveform sequence; when three correction drive frames are set and two replaced key drive frames are set, corresponding to the first color value after the ink screen is driven according to the first key drive frame to the third last key drive frame in the first waveform sequence.
According to the scheme, when the driving compensation parameter from the first color value to the second color value of an image pixel point is determined according to the first color value and the second color value corresponding to the image to be displayed, the method specifically comprises the following steps: and determining a second number of correction drive frames of each image pixel point of the image to be displayed according to the first color value and a second color value corresponding to the image to be displayed. Correspondingly, when the driving compensation parameters are used for performing driving compensation processing on the first waveform sequence corresponding to each image pixel point, the method specifically comprises the following steps: and replacing the last key driving frame in the first waveform sequence of the corresponding image pixel point by using the second number of corrected driving frames.
For example, after determining the first waveform sequence corresponding to the image to be displayed, after further determining that each image pixel in the image to be displayed drives the ink screen based on the first key driving frame to the last but one number of previous key driving frames in the corresponding first waveform sequence, determining, for each image pixel, a corresponding first color value after driving the ink screen according to the first key driving frame to the last but one number of previous key driving frames in the first waveform sequence, according to the estimated color determination relationship, at the current color value. Furthermore, for each image pixel point of the image to be displayed, determining a second number of correction drive frames from the corresponding first color value to the corresponding second color value of each image pixel point in the image to be displayed according to the first color value and the corresponding second color value. The determination of the modified driving frame may be performed based on a waveform file, that is, a second number of driving frames corresponding to the first color value to the second color value are determined in the waveform file, and the corresponding driving frames are used as modified driving frames, and the modified driving frames may also be determined based on an estimated color mapping relationship, that is, a second number of driving frames corresponding to the first color value to the second color value are determined based on the estimated color mapping relationship, and the corresponding driving frames are used as modified driving frames. Further, for each image pixel of the image to be displayed, the last first number of key drive frames in the first waveform sequence corresponding to the image pixel are replaced with the second number of modified drive frames in the determined drive compensation parameter (i.e., the last first number of key drive frames are deleted, and the determined second number of modified drive frames are inserted), so that the drive compensation processing on the first waveform sequence is realized. At this time, the driving frames in the first waveform sequence include a second number of modified driving frames replacing the first last number of key driving frames, in addition to the first to last number of previous key driving frames in the original first waveform sequence. For example, when the number of the modified driving frames is five and the number of the replaced key driving frames is two, the first color value is determined based on the first key driving frame to the third last key driving frame in the first waveform sequence, and the key driving frames in the second waveform sequence further include five modified driving frames replacing the original last two key driving frames in addition to corresponding to the first key driving frame to the third last key driving frame in the first waveform sequence.

Illustratively, after the driving compensation processing is performed on the first waveform sequences, the sequence lengths (which can be represented by the number of included driving frames) corresponding to the first waveform sequences are further determined. Further, the first waveform sequence with the longest sequence length is determined as the longest first waveform sequence in each image pixel point in the image to be displayed.
S205: and performing frame supplementing alignment processing on the first waveform sequences of other image pixel points in the image to be displayed based on the longest first waveform sequence to obtain a second waveform sequence corresponding to each image pixel point in the image to be displayed.
Illustratively, after the longest first waveform sequence is determined, frame supplementing and aligning the first waveform sequences of the pixels of other images in the image to be displayed are performed, so that the sequence lengths of the first waveform sequences of the pixels of other images in the image to be displayed are consistent with the sequence length of the longest first waveform sequence, and a second waveform sequence corresponding to each image pixel point in each image to be displayed is obtained.
In one possible embodiment, the complementary frame alignment process may be performed by inserting an invalid frame into the first waveform sequence. Based on this, when the frame supplementing alignment processing is performed on the first waveform sequences of the other image pixel points in the image to be displayed, the method specifically comprises the following steps: and inserting an invalid frame into the first waveform sequences of other image pixel points so as to align the sequence length of the first waveform sequences of other image pixel points with the longest first waveform sequence.
When the ink screen is driven based on the invalid frame, the color value of the corresponding screen pixel point of the ink screen is kept unchanged, and based on the color value, the invalid frame can be utilized to supplement the frame alignment processing, so that the screen display effect is not influenced while the uniformity of the screen updating process is ensured. For example, after the longest first waveform sequence is determined, an invalid frame is inserted into each first waveform sequence other than the longest first waveform sequence, so that the number of drive frames included in each first waveform sequence is consistent with the number of drive frames corresponding to the longest first waveform sequence (at this time, all the drive frames are key drive frames), and at this time, the sequence lengths of the first waveform sequences of other image pixels are aligned with the longest first waveform sequence. The second waveform sequence corresponding to the longest first waveform sequence is consistent with the first waveform sequence, that is, an invalid frame does not need to be inserted into the longest first waveform sequence. Alternatively, when inserting the invalid frame into the first waveform sequence, the inserting position of the invalid frame may be at the head, middle or end of the first waveform sequence, or may be randomly inserted.
S206: and driving an ink screen to display the image to be displayed based on the second waveform sequence.
And after the second waveform sequences corresponding to the pixel points of each image are determined, driving the ink screen according to the second waveform sequences so as to convert the image displayed by the ink screen from the current display image into the image to be displayed.
In a possible embodiment, the determining, according to the first color value and the second color value corresponding to the image to be displayed, a driving compensation parameter of an image pixel point from the first color value to the second color value includes:
determining a compensation strategy for the first waveform sequence according to a set driving compensation mode; and determining a driving compensation parameter of an image pixel point from the first color value to the second color value according to the first color value and the second color value corresponding to the image to be displayed based on the compensation strategy.
The compensation strategy provided by the embodiment is used for indicating the compensation intensity for compensating the first waveform sequence, and different compensation strategies correspond to different compensation intensities. For example, after the first color value corresponding to each image pixel point is determined, the currently set driving compensation mode is determined, and the compensation strategy corresponding to the current driving compensation mode is determined. Furthermore, according to the compensation intensity corresponding to the determined driving compensation strategy, and according to the first color value and the second color value corresponding to each image pixel point in the image to be displayed, a driving compensation parameter (compensation frame) from the first color value to the corresponding second color value of each image pixel point is determined. The stronger the compensation intensity corresponding to the driving compensation strategy is, the larger the number of compensation frames is, namely, the stronger the compensation intensity of the first waveform sequence is, and the color value displayed by the ink screen is driven to be closer to the second color value (target color value) according to the compensated second waveform sequence. According to the scheme, the first waveform sequence is subjected to driving compensation with different compensation intensities through compensation strategies in different driving compensation modes, so that the requirements of users on the picture display quality and the picture display speed in different use scenes are met, and the use experience of the users is optimized.
In one possible embodiment, the drive compensation mode may be automatically set by the ink screen display control device, for example, the ink screen display control device determines based on the current operating mode of the ink screen. Optionally, the driving compensation mode with lower compensation intensity may be set in the working mode with higher requirement on the screen refresh rate, for example, in different working modes such as a reading mode, a picture mode, a web page mode, a video mode, and the like, the driving compensation mode corresponds to different driving compensation modes, and the compensation intensity corresponding to the compensation strategy of the driving compensation mode is sequentially reduced.
In one possible embodiment, the driving compensation mode may also be set according to a compensation mode setting operation in which a user sets the driving compensation mode of the ink screen display control device. Based on this, the ink screen display control method provided by the scheme further comprises the following steps: the driving compensation mode is updated according to the received compensation mode setting operation.
For example, a driving compensation configuration interface for configuring the driving compensation mode may be provided on the ink screen display control device, and a selection list of different driving compensation modes may be provided on the driving compensation configuration interface. When a user needs to configure a driving compensation mode, the user can select the required driving compensation mode on a driving compensation configuration interface, or configure corresponding driving compensation modes for different working modes, or configure corresponding driving compensation modes for different time periods, so as to trigger a compensation mode setting operation. And after receiving the compensation mode setting operation, updating the driving compensation mode according to the selection of the driving compensation mode by the compensation mode setting operation. According to the scheme, the driving compensation mode is updated according to the compensation mode setting operation triggered by the user, the flexible setting requirements of the user on the picture display quality and the picture display speed under different use scenes are met, and the use experience of the user is optimized.
In one possible embodiment, the ink screen display control method provided by the present disclosure further includes: under the condition that a first compensation switch of the ink screen is turned on, determining that the driving compensation parameters are utilized to carry out driving compensation processing on a first waveform sequence corresponding to each image pixel point; and/or under the condition that a second compensation switch of the ink screen is turned on, when the image to be displayed is determined to be the final display image, driving the ink screen to perform color compensation by using a third waveform sequence.
It should be explained that the first compensation switch is used to control whether the driving compensation process is required to be performed on the first waveform sequence, and the second compensation switch is used to control whether the color compensation is required to be performed by driving the ink screen with the third waveform sequence.
The first compensation switch comprises an on-off state and an off-on state, and under the condition that the on-off state of the first compensation switch of the ink screen is on, the first waveform sequence corresponding to each image pixel point is determined to be driven and compensated by using the driving compensation parameters, namely after the first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, the first color value corresponding to each image pixel point, which is driven by the ink screen based on the corresponding first waveform sequence, needs to be determined, and the driving compensation processing is performed on the first waveform sequence corresponding to each image pixel point according to the first color value and the second color value corresponding to each image pixel point in the image to be displayed. And under the condition that the on-off state of the first compensation switch of the ink screen is closed, determining that the driving compensation parameter is not required to be used for carrying out driving compensation processing on the first waveform sequence corresponding to each image pixel point, namely after the first waveform sequence corresponding to each image pixel point in the image to be displayed is determined, directly carrying out frame supplementing alignment processing on the first waveform sequence to obtain a second waveform sequence corresponding to each image pixel point in the image to be displayed, and driving the ink screen to display the image to be displayed based on the second waveform sequence.
The second compensation switch comprises an on state and an off state, under the condition that the on-off state of the second compensation switch for the ink screen is on, when the image to be displayed is determined to be a final display image, the third waveform sequence is used for driving the ink screen to perform color compensation, 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 from the third color value to the corresponding second color value of each screen pixel point is determined according to the third color value corresponding to each screen pixel point and the image to be displayed, and then the ink screen is driven to display the image to be displayed based on the third waveform sequence. And under the condition that the on-off state of the second compensation switch of the ink screen is closed, determining whether the image to be displayed is the final display image or not, 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 switching state of the first compensation switch and/or the second 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.
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. After the first waveform sequence composed of the key driving frames is determined, the number of the key driving frames corresponding to the 4 first waveform sequences of the image to be displayed is assumed to be 15 frames, 16 frames and 18 frames respectively.
If one or more compensation driving frames (taking 1 compensation driving frame as an example) are used to perform driving compensation processing on the first waveform sequence, the number of driving frames corresponding to the first waveform sequence at this time is 16 frames (15 key driving frames +1 compensation driving frames), 17 frames (16 key driving frames +1 compensation driving frames), and 19 frames (18 key driving frames +1 compensation driving frames), respectively. After the frame supplementing alignment processing is carried out on the first waveform sequences, the number of the key frames corresponding to the 4 second waveform sequences is 19 frames, the driving time for driving the ink screen to display the image to be displayed based on the second waveform sequences is 380ms, and the refreshing efficiency of the ink screen is obviously improved.
If the first waveform sequence is subjected to drive compensation processing by using a second number of modified drive frames (assuming that three modified drive frames are provided and two replaced key drive frames are provided), the number of drive frames corresponding to the first waveform sequence is 17 frames (14 key drive frames +3 modified drive frames), 18 frames (15 key drive frames +3 modified drive frames), and 20 frames (17 key drive frames +3 modified drive frames), respectively. Then, after the frame complementing alignment processing is performed on the first waveform sequences, the number of the obtained key frames corresponding to the 4 second waveform sequences is 20 frames, and then the driving time for driving the ink screen to display the image to be displayed based on the second waveform sequences is 400ms, so that the ink screen refreshing efficiency is obviously improved.
In an embodiment, since there may be a situation of insufficient compensation capability after compensating the first waveform sequence, the ink screen may not accurately display the corresponding target color, and the estimated third color value after compensation needs to be estimated as the actual display color. Based on this, after obtaining the second waveform sequence corresponding to each image pixel point or driving the ink screen to display the image to be displayed based on the second waveform sequence, the method for controlling the display of the ink screen provided by the present scheme further includes: and determining an estimated third color value corresponding to each image pixel point when the ink screen is driven to display based on the second waveform sequence, namely determining that each image pixel point in the image to be displayed drives the ink screen to display the corresponding estimated third color value according to all the driving frames in the corresponding second waveform sequence, wherein the estimated third color value can be used as a current color value corresponding to a screen pixel point on the ink screen corresponding to the next frame of image to be displayed (the next round of ink screen display control method processing flow) displayed by the ink screen.
The method includes the steps that a first waveform sequence corresponding to each image pixel point in an image to be displayed is determined, frame supplementing alignment processing is carried out on the first waveform sequence to obtain a second waveform sequence, the ink screen is driven to display the image to be displayed based on the second waveform sequence, the second waveform is obtained by carrying out frame supplementing alignment processing on the first waveform sequence formed by a plurality of key driving frames, time consumed by non-key frames or invalid frames when the ink screen is driven is reduced, the ink screen refreshing speed is improved, the second waveform sequences of the image pixel points are aligned by carrying out frame supplementing alignment processing on the first waveform sequence, normal driving of the ink screen is guaranteed, and image display quality is guaranteed. Meanwhile, the original first waveform sequence is subjected to drive compensation processing according to the drive compensation parameters, so that the situation that the image display quality is reduced due to the reduction of non-key drive frames is reduced, and the image display quality is ensured. Meanwhile, when the first waveform sequence is driven and compensated, one or more compensation driving frames are 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; and determining a second number of correction drive frames according to the drive requirements of the first color value and the second color value corresponding to each image pixel point after the first key drive frame in the first waveform sequence of the first waveform sequence is driven to the last key drive frame with the first number, and performing drive compensation on the first waveform sequence, thereby effectively ensuring the accuracy of the displayed image after the display acceleration.
