技术领域Technical Field
本申请实施例涉及显示技术领域，尤其涉及一种墨水屏的驱动方法、装置、电子设备以及存储介质。The embodiments of the present application relate to the field of display technology, and in particular to a driving method, device, electronic device and storage medium for an ink screen.
背景技术Background Art
电子墨水屏利用电泳技术实现接近传统纸张的显示效果，因此也被成为“电子纸”。电子墨水屏一般通过电子墨水进行画面显示，电子墨水通常会制成电子墨水薄膜的形式，电子墨水薄膜由大量微囊组成，微囊中设置有带不同电荷的色素颗粒。初始状态下，色素颗粒悬浮在微囊中，当施加一定方向的电场后，相应的色素颗粒被推到顶部，微囊就会显示不同的颜色，而不同颜色的微囊组成了各种文字和图案。Electronic ink screens use electrophoresis technology to achieve a display effect close to that of traditional paper, so they are also called "electronic paper". Electronic ink screens generally display images through electronic ink, which is usually made into the form of electronic ink films. The electronic ink films are composed of a large number of microcapsules, and the microcapsules are equipped with pigment particles with different charges. In the initial state, the pigment particles are suspended in the microcapsules. When an electric field in a certain direction is applied, the corresponding pigment particles are pushed to the top, and the microcapsules will display different colors. Microcapsules of different colors form various texts and patterns.
而为了控制每个像素对应的墨水胶囊的变化，使像素点呈现目标颜色值（像素点在待显示画面中的颜色值），现有技术会通过向墨水屏的屏幕驱动模块发送驱动波形序列来控制像素对应的墨水胶囊，驱动波形序列包含了前述墨水胶囊两侧电极之间的电压差（驱动电压）的变化信号以及变化信号的持续时间（以帧的形式表征），屏幕驱动模块根据驱动波形序列来控制墨水胶囊，使像素颜色值发生变化。In order to control the changes of the ink capsules corresponding to each pixel so that the pixel point presents the target color value (the color value of the pixel point in the image to be displayed), the prior art controls the ink capsules corresponding to the pixels by sending a driving waveform sequence to the screen driving module of the ink screen. The driving waveform sequence includes a change signal of the voltage difference (driving voltage) between the electrodes on both sides of the ink capsule and the duration of the change signal (represented in the form of frames). The screen driving module controls the ink capsules according to the driving waveform sequence to change the pixel color value.
然而现有技术通常是采用遍历各个像素地比较当前画面和待显示画面，然后再根据各个像素的当前颜色值和目标颜色值计算出各个像素的驱动波形序列。显然，驱动波形序列的计算过程会影响画面刷新速度，为了满足用户对于电子墨水屏快速刷新的要求，有必要对电子墨水屏的驱动方法进行优化。However, the prior art usually compares the current image with the image to be displayed by traversing each pixel, and then calculates the driving waveform sequence of each pixel according to the current color value and the target color value of each pixel. Obviously, the calculation process of the driving waveform sequence will affect the image refresh speed. In order to meet the user's requirements for fast refresh of the electronic ink screen, it is necessary to optimize the driving method of the electronic ink screen.

其中，所述历史波形数据至少包括与当前显示画面具有相同刷新模式的历史显示画面的波形数据，所述历史颜色参数包括所述墨水屏的像素点在显示历史画面时的初始颜色参数值以及最终颜色参数值，也即是每个所述历史颜色参数包括两个颜色参数值，而每个历史波形数据与历史颜色参数一一对应。Among them, the historical waveform data at least includes waveform data of historical display pictures with the same refresh mode as the current display picture, and the historical color parameters include the initial color parameter value and the final color parameter value of the pixel points of the ink screen when displaying the historical picture, that is, each of the historical color parameters includes two color parameter values, and each historical waveform data corresponds one-to-one to the historical color parameter.
另外，所述初始颜色参数值为所述墨水屏的像素点在显示画面时的初始颜色值的相关参数，所述最终颜色参数值为所述墨水屏的像素点在显示画面时的最终颜色值的相关参数。所述当前颜色参数值为所述墨水屏的像素点在显示当前显示画面时的初始颜色值的相关参数，所述目标颜色参数值为所述墨水屏的像素点在显示当前显示画面时的最终颜色值的相关参数。In addition, the initial color parameter value is a parameter related to the initial color value of the pixel point of the ink screen when displaying the picture, and the final color parameter value is a parameter related to the final color value of the pixel point of the ink screen when displaying the picture. The current color parameter value is a parameter related to the initial color value of the pixel point of the ink screen when displaying the current display picture, and the target color parameter value is a parameter related to the final color value of the pixel point of the ink screen when displaying the current display picture.
进一步地，在本申请一实施例中，所述初始颜色参数值为初始灰度值，所述最终颜色参数值为最终灰度值，所述当前颜色参数值为当前灰度值，所述目标颜色参数值为目标灰度值。当然在本申请另一实施例中，所述初始颜色参数值可以为初始亮度值，所述最终颜色参数值可以为最终亮度值，所述当前颜色参数值可以为当前亮度值，所述目标颜色参数值可以为目标亮度值。Furthermore, in one embodiment of the present application, the initial color parameter value is an initial gray value, the final color parameter value is a final gray value, the current color parameter value is a current gray value, and the target color parameter value is a target gray value. Of course, in another embodiment of the present application, the initial color parameter value may be an initial brightness value, the final color parameter value may be a final brightness value, the current color parameter value may be a current brightness value, and the target color parameter value may be a target brightness value.
步骤S20、判断所述历史颜色参数中是否具有所述初始颜色参数值与所述当前颜色参数值相同且所述最终颜色参数值与所述目标颜色参数值相同的第一历史颜色参数。Step S20: Determine whether the historical color parameters include a first historical color parameter whose initial color parameter value is the same as the current color parameter value and whose final color parameter value is the same as the target color parameter value.

也即是，当所述历史颜色参数中具有所述初始颜色参数值与所述当前颜色参数值相同且所述最终颜色参数值与所述目标颜色参数值相同的第一历史颜色参数时，此时则代表所述波形缓存器中存在所述墨水屏的像素点在显示当前显示画面时所需要的驱动波形数据，因此只需要通过所述第一历史颜色参数即可获得与所述第一历史颜色参数相对应的第一历史波形数据，所述第一历史波形数据为所述墨水屏的像素点的驱动波形序列，因此不需要通过对比当前显示画面和待显示画面后计算得到所述墨水屏的像素点的驱动波形序列。That is, when the historical color parameters include a first historical color parameter in which the initial color parameter value is the same as the current color parameter value and the final color parameter value is the same as the target color parameter value, this means that the waveform buffer contains the driving waveform data required for the pixels of the ink screen when displaying the current display screen. Therefore, it is only necessary to use the first historical color parameter to obtain the first historical waveform data corresponding to the first historical color parameter. The first historical waveform data is the driving waveform sequence of the pixels of the ink screen. Therefore, there is no need to calculate the driving waveform sequence of the pixels of the ink screen by comparing the current display screen with the screen to be displayed.
步骤S40、判断结果为否，则根据所述当前颜色参数值与所述目标颜色参数值得到所述墨水屏的像素点的驱动波形序列。Step S40: If the judgment result is no, a driving waveform sequence of the pixel points of the ink screen is obtained according to the current color parameter value and the target color parameter value.
当所述历史颜色参数中不具有所述初始颜色参数值与所述当前颜色参数值相同且所述最终颜色参数值与所述目标颜色参数值相同的第一历史颜色参数时，则采用常规方式，根据所述当前颜色参数值与所述目标颜色参数值得到所述墨水屏的像素点的驱动波形序列。When the historical color parameters do not contain a first historical color parameter in which the initial color parameter value is the same as the current color parameter value and the final color parameter value is the same as the target color parameter value, a conventional method is adopted to obtain a driving waveform sequence for the pixel points of the ink screen according to the current color parameter value and the target color parameter value.
步骤S50、利用所述驱动波形序列驱动所述墨水屏显示所述待显示画面。Step S50: using the driving waveform sequence to drive the ink screen to display the image to be displayed.
综上，本申请通过判断所述历史颜色参数中是否具有所述初始颜色参数值与所述当前颜色参数值相同且所述最终颜色参数值与所述目标颜色参数值相同的第一历史颜色参数，从而得知所述波形缓存器是否存在与所述墨水屏的像素点在显示待显示画面时相同的颜色参数，如果是则获得与所述第一历史颜色参数相对应的第一历史波形数据，所述第一历史波形数据为所述墨水屏的像素点的驱动波形序列，如果否则根据所述当前颜色参数值与所述目标颜色参数值得到所述墨水屏的像素点的驱动波形序列，从而可以减少驱动波形序列的计算工作量，而提高所述墨水屏的画面刷新速度。In summary, the present application determines whether the waveform buffer has the same color parameters as the pixels of the ink screen when displaying the image to be displayed by judging whether the historical color parameters contain a first historical color parameter whose initial color parameter value is the same as the current color parameter value and whose final color parameter value is the same as the target color parameter value. If so, the first historical waveform data corresponding to the first historical color parameter is obtained, and the first historical waveform data is the driving waveform sequence of the pixels of the ink screen. Otherwise, the driving waveform sequence of the pixels of the ink screen is obtained according to the current color parameter value and the target color parameter value, thereby reducing the calculation workload of the driving waveform sequence and improving the screen refresh speed of the ink screen.

所述墨水屏在显示画面时都会采用某种刷新模式，由于刷新模式的不同也可能导致驱动波形不同，为了提高驱动波形的准确性，本申请通过判断所述当前刷新模式和所述目标刷新模式是否相同来决定获取驱动波形的方式。具体地，当所述当前刷新模式和所述目标刷新模式相同时，则执行执行下一步，也即是执行步骤S20；当所述当前刷新模式和所述目标刷新模式不相同时，则根据所述当前颜色参数值与所述目标颜色参数值得到所述墨水屏的像素点的驱动波形序列并跳过下一步，也即是跳过步骤S20，然后执行步骤S50，利用所述驱动波形序列驱动所述墨水屏显示所述待显示画面。The ink screen will adopt a certain refresh mode when displaying a picture. Since different refresh modes may also lead to different driving waveforms, in order to improve the accuracy of the driving waveform, the present application determines the method of obtaining the driving waveform by judging whether the current refresh mode and the target refresh mode are the same. Specifically, when the current refresh mode and the target refresh mode are the same, the next step is executed, that is, step S20 is executed; when the current refresh mode and the target refresh mode are different, the driving waveform sequence of the pixel points of the ink screen is obtained according to the current color parameter value and the target color parameter value and the next step is skipped, that is, step S20 is skipped, and then step S50 is executed to drive the ink screen to display the picture to be displayed using the driving waveform sequence.
其中，所述墨水屏的刷新模式包括：A2刷新模式、DU刷新模式、GC刷新模式（包括GC4刷新模式、GC8刷新模式和GC16刷新模式）、GU刷新模式、GL刷新模式和GLR刷新模式。具体地：The refresh modes of the ink screen include: A2 refresh mode, DU refresh mode, GC refresh mode (including GC4 refresh mode, GC8 refresh mode and GC16 refresh mode), GU refresh mode, GL refresh mode and GLR refresh mode. Specifically:
A2刷新模式：把原来显示的灰阶内容以黑白呈现，以减少渲染灰阶所带来的时间及电源消耗，刷新速度最快。A2 refresh mode: The original grayscale content is presented in black and white to reduce the time and power consumption of grayscale rendering, and the refresh speed is the fastest.
DU刷新模式：把原来显示的灰阶内容以黑白呈现，刷新速度仅次于A2刷新模式，但残影比A2刷新模式少。DU refresh mode: The original grayscale content is displayed in black and white. The refresh speed is second only to the A2 refresh mode, but the afterimage is less than the A2 refresh mode.
GC刷新模式：所有像素都重新输出，在输出之前，先进行一次清屏操作，其可细分为GC4刷新模式、GC刷新模式8、GC16刷新模式等，分别表示可以支援4种、8种及16种灰阶，刷新速度最慢，但残影最少。GC刷新模式又称为全屏刷新，即整个页面全部刷新一次，不论同一个像素的前后灰阶是否改变。GC refresh mode: All pixels are re-output. Before output, a screen clearing operation is performed. It can be subdivided into GC4 refresh mode, GC refresh mode 8, GC16 refresh mode, etc., which means that 4, 8 and 16 grayscales can be supported respectively. The refresh speed is the slowest, but the residual image is the least. GC refresh mode is also called full screen refresh, that is, the entire page is refreshed once, regardless of whether the grayscale of the same pixel before and after changes.
GU刷新模式：在数据输出之前不进行清屏操作，直接输出与上次输出发生变化的像素，包括GU8刷新模式、GU16刷新模式等，分别表示支援8种及16种灰阶，其较A2刷新模式、DU刷新模式的刷新速度慢，但较GC刷新模式的刷新速度快。GU刷新模式又称为局部刷新，翻页时速度能接受，并且页面变化也比较平顺。GU refresh mode: before data output, the screen is not cleared, and the pixels that have changed from the last output are directly output, including GU8 refresh mode and GU16 refresh mode, which support 8 and 16 grayscales respectively. The refresh speed is slower than A2 refresh mode and DU refresh mode, but faster than GC refresh mode. GU refresh mode is also called partial refresh. The speed is acceptable when turning pages, and the page changes are relatively smooth.
GL刷新模式：在数据输出之前不进行清屏操作，一般为GL16刷新模式，也就是支援16种灰阶，其较A2刷新模式、DU刷新模式的刷新速度慢，但较GC刷新模式的刷新速度快。GL刷新模式亦为局部刷新。GL refresh mode: No screen clearing is performed before data output. This is usually the GL16 refresh mode, which supports 16 grayscales. Its refresh speed is slower than the A2 refresh mode and the DU refresh mode, but faster than the GC refresh mode. The GL refresh mode is also a partial refresh.
GLR刷新模式：又称为“regal”，一般为GLR16刷新模式，也就是支援16种灰阶，类似于局部刷新，刷新的方式取决于前后画面之间的差异，特别之处在于如果前后画面由黑到黑时，会经过黑白黑的闪刷。刷新速度与前述局部刷新模式接近，残影少。GLR refresh mode: Also known as "regal", generally GLR16 refresh mode, that is, supports 16 grayscales, similar to partial refresh, the refresh method depends on the difference between the front and back images, the special thing is that if the front and back images change from black to black, they will flash black and white to black. The refresh speed is close to the aforementioned partial refresh mode, with less afterimages.

Based on the driving method provided in Figure 2, further, in an embodiment of the present application, the step of determining whether the current refresh mode and the target refresh mode are the same, if yes, executing the next step, if not, obtaining the driving waveform sequence of the pixel points of the ink screen according to the current color parameter value and the target color parameter value and skipping the next step includes:

If so, execute the next step. If not, obtain the driving waveform sequence of the pixel points of the ink screen according to the current color parameter value and the target color parameter value, skip the next step, and clear the data in the waveform buffer.

步骤S71、判断所述当前刷新模式和所述目标刷新模式是否相同，如果是则执行下一步，也即是执行步骤S20；Step S71, determining whether the current refresh mode and the target refresh mode are the same, if yes, executing the next step, that is, executing step S20;
步骤S81、如果否则根据所述当前颜色参数值与所述目标颜色参数值得到所述墨水屏的像素点的驱动波形序列并跳过下一步，也即是跳过步骤S20，并清空所述波形缓存器的数据。然后执行步骤S50，也即是利用所述驱动波形序列驱动所述墨水屏显示所述待显示画面。Step S81: If not, the driving waveform sequence of the pixel points of the ink screen is obtained according to the current color parameter value and the target color parameter value and the next step is skipped, that is, step S20 is skipped, and the data in the waveform buffer is cleared. Then step S50 is executed, that is, the driving waveform sequence is used to drive the ink screen to display the picture to be displayed.
由于刷新模式的不同也可能导致驱动波形不同，因此当所述当前刷新模式和所述目标刷新模式不相同时，则根据所述当前颜色参数值与所述目标颜色参数值得到所述墨水屏的像素点的驱动波形序列并跳过下一步，也即是执行步骤S20，同时并清空所述波形缓存器的数据，以避免在执行步骤S20时出现错误判断。在所述波形缓存器的数据被清空后，所述波形缓存器继续存储在所述目标刷新模式下产生的波形数据以及与所述波形数据一一对应的颜色参数。Since different refresh modes may also lead to different driving waveforms, when the current refresh mode and the target refresh mode are different, the driving waveform sequence of the pixel points of the ink screen is obtained according to the current color parameter value and the target color parameter value and the next step is skipped, that is, step S20 is executed, and the data in the waveform buffer is cleared at the same time to avoid erroneous judgment when executing step S20. After the data in the waveform buffer is cleared, the waveform buffer continues to store the waveform data generated in the target refresh mode and the color parameters corresponding to the waveform data.

步骤S90、判断所述当前颜色参数值和所述目标颜色参数值是否相同，如果是则不执行下一步，如果否则执行下一步。Step S90, determine whether the current color parameter value is the same as the target color parameter value, if yes, do not execute the next step, if not, execute the next step.
也即是，本申请在所述判断所述历史颜色参数中是否具有所述初始颜色参数值与所述当前颜色参数值相同且所述最终颜色参数值与所述目标颜色参数值相同的第一历史颜色参数的步骤之前，先判断判断所述当前颜色参数值和所述目标颜色参数值是否相同，当所述当前颜色参数值和所述目标颜色参数值相同时，则代表与所述当前颜色参数值和所述目标颜色参数值相关联的所述墨水屏的像素在待显示画面是颜色不变像素，此时无需对颜色不变像素进行驱动，则不执行步骤S20；当所述当前颜色参数值和所述目标颜色参数值不相同时，则代表与所述当前颜色参数值和所述目标颜色参数值相关联的所述墨水屏的像素在待显示画面是颜色变化像素，此时需要对颜色变化像素进行驱动，则执行步骤S20。That is, before the step of determining whether the historical color parameters contain a first historical color parameter in which the initial color parameter value is the same as the current color parameter value and the final color parameter value is the same as the target color parameter value, the present application first determines whether the current color parameter value and the target color parameter value are the same. When the current color parameter value and the target color parameter value are the same, it means that the pixels of the ink screen associated with the current color parameter value and the target color parameter value are color-unchanged pixels in the screen to be displayed. In this case, there is no need to drive the color-unchanged pixels, and step S20 is not executed. When the current color parameter value and the target color parameter value are different, it means that the pixels of the ink screen associated with the current color parameter value and the target color parameter value are color-changing pixels in the screen to be displayed. In this case, the color-changing pixels need to be driven, and step S20 is executed.
请参考图5，图5为本申请提供的一种墨水屏的驱动方法的实施例五的流程图。进一步地，在图1所提供的驱动方法的基础上，在所述步骤S20之前，所述驱动方法包括：Please refer to FIG5 , which is a flow chart of a fifth embodiment of a method for driving an ink screen provided by the present application. Further, based on the driving method provided in FIG1 , before step S20 , the driving method includes:
步骤S90、判断所述当前颜色参数值和所述目标颜色参数值是否相同；Step S90, determining whether the current color parameter value is the same as the target color parameter value;
步骤S100、所述当前颜色参数值和判断所述目标颜色参数值相同时，则获得所述墨水屏的像素点的灰度值不发生变化的时长，并判断所述时长是否大于预设阈值，所述时长不大于预设阈值时，则直接执行下一步也即是执行步骤S20；Step S100: When the current color parameter value and the target color parameter value are determined to be the same, the duration during which the grayscale value of the pixel of the ink screen does not change is obtained, and it is determined whether the duration is greater than a preset threshold. When the duration is not greater than the preset threshold, the next step is directly executed, that is, step S20 is executed.
步骤S200、所述时长大于预设阈值时，则对所述墨水屏的像素点的灰度值进行复位后再恢复至所述当前颜色参数值所对应的当前灰度值，然后执行下一步也即是执行步骤S20；Step S200, when the duration is greater than the preset threshold, the grayscale value of the pixel of the ink screen is reset and then restored to the current grayscale value corresponding to the current color parameter value, and then the next step is executed, that is, step S20;
所述当前颜色参数值和判断所述目标颜色参数值不相同时，则执行下一步，也即是执行步骤S20。When the current color parameter value and the target color parameter value are judged to be different, the next step is executed, that is, step S20 is executed.
也即是，本申请在所述判断所述历史颜色参数中是否具有所述初始颜色参数值与所述当前颜色参数值相同且所述最终颜色参数值与所述目标颜色参数值相同的第一历史颜色参数的步骤之前，先判断判断所述当前颜色参数值和所述目标颜色参数值是否相同。That is, before the step of determining whether the historical color parameters contain a first historical color parameter in which the initial color parameter value is the same as the current color parameter value and the final color parameter value is the same as the target color parameter value, the present application first determines whether the current color parameter value and the target color parameter value are the same.
当所述当前颜色参数值和所述目标颜色参数值相同时，则代表与所述当前颜色参数值和所述目标颜色参数值相关联的所述墨水屏的像素在待显示画面是颜色不变像素，此时则获得所述墨水屏的像素点的灰度值不发生变化的时长，并判断所述时长是否大于预设阈值。When the current color parameter value and the target color parameter value are the same, it means that the pixels of the ink screen associated with the current color parameter value and the target color parameter value are color-unchanged pixels in the image to be displayed. At this time, the time length during which the grayscale value of the pixel point of the ink screen does not change is obtained, and it is determined whether the time length is greater than a preset threshold.
当所述时长大于预设阈值，则表示所述墨水屏的像素点处于不变状态太久，所述墨水屏的像素点的实际颜色有可能失真，因此对所述墨水屏的像素点的灰度值进行复位后再恢复至所述当前颜色参数值所对应的当前灰度值，也即是恢复至所述当前颜色参数值所对应的颜色值，然后执行下一步也即是执行步骤S20；当所述时长不大于预设阈值，则表示所述墨水屏的像素点处于不变状态的时长还在预设阈值内，所述墨水屏的像素点的实际颜色不会失真，此时无需对颜色不变像素进行驱动，则执行下一步，也即是执行步骤S20。When the duration is greater than the preset threshold, it means that the pixel points of the ink screen have been in an unchanged state for too long, and the actual color of the pixel points of the ink screen may be distorted. Therefore, the grayscale value of the pixel points of the ink screen is reset and then restored to the current grayscale value corresponding to the current color parameter value, that is, restored to the color value corresponding to the current color parameter value, and then the next step is executed, that is, step S20 is executed; when the duration is not greater than the preset threshold, it means that the duration of the pixel points of the ink screen being in an unchanged state is still within the preset threshold, and the actual color of the pixel points of the ink screen will not be distorted. At this time, there is no need to drive the color-unchanged pixels, and then the next step is executed, that is, step S20 is executed.
当所述当前颜色参数值和所述目标颜色参数值不相同时，则代表与所述当前颜色参数值和所述目标颜色参数值相关联的所述墨水屏的像素在待显示画面是颜色变化像素，此时需要对颜色变化像素进行驱动，则执行下一步，也即是执行步骤S20。When the current color parameter value and the target color parameter value are different, it means that the pixels of the ink screen associated with the current color parameter value and the target color parameter value are color-changing pixels in the screen to be displayed. At this time, the color-changing pixels need to be driven, and the next step is executed, that is, step S20.
请参考图6，图6为本申请提供的一种墨水屏的驱动方法的步骤S100的部分流程图。进一步地，在图5所提供的驱动方法的基础上，所述历史画面包括当前显示画面；所述获得所述墨水屏的像素点的灰度值不发生变化的时长的步骤，包括：Please refer to FIG. 6, which is a partial flow chart of step S100 of a method for driving an ink screen provided by the present application. Further, based on the driving method provided by FIG. 5, the historical screen includes the current display screen; the step of obtaining the duration during which the grayscale value of the pixel point of the ink screen does not change includes:
步骤S101、从所述当前显示画面开始依次地将所述墨水屏的像素点在显示每个历史画面时的初始颜色参数值和最终颜色参数值进行对比，当所述墨水屏的像素点在显示第N个历史画面时的初始颜色参数值和最终颜色参数值不相同时，则停止对比；Step S101, starting from the current display screen, sequentially comparing the initial color parameter value and the final color parameter value of the pixel point of the ink screen when displaying each historical screen, and stopping the comparison when the initial color parameter value and the final color parameter value of the pixel point of the ink screen when displaying the Nth historical screen are different;
步骤S102、获得所述墨水屏的像素点从第一个历史画面至第N-1个历史画面的显示时长，所述显示时长为所述墨水屏的像素点的灰度值不发生变化的时长，所述第一个历史画面为当前显示画面。Step S102, obtaining the display time of the pixels of the ink screen from the first historical screen to the N-1th historical screen, wherein the display time is the time during which the grayscale value of the pixels of the ink screen does not change, and the first historical screen is the currently displayed screen.
具体地，所述墨水屏的像素点的灰度值不发生变化是指所述墨水屏的像素点在显示画面时的初始颜色参数值和最终颜色参数值是相同的，因此从所述当前显示画面开始依次地将所述墨水屏的像素点在显示每个历史画面时的初始颜色参数值和最终颜色参数值进行对比，当所述墨水屏的像素点在显示第N个历史画面时的初始颜色参数值和最终颜色参数值不相同时，此时代表所述墨水屏的像素点在显示第N个历史画面时的灰度值发生变化，则停止对比。然后计算得到所述墨水屏的像素点从第一个历史画面至第N-1个历史画面的显示时长，所述显示时长为所述墨水屏的像素点的灰度值不发生变化的时长。Specifically, the grayscale value of the pixel of the ink screen does not change means that the initial color parameter value and the final color parameter value of the pixel of the ink screen when displaying the picture are the same. Therefore, starting from the current display picture, the initial color parameter value and the final color parameter value of the pixel of the ink screen when displaying each historical picture are compared in sequence. When the initial color parameter value and the final color parameter value of the pixel of the ink screen when displaying the Nth historical picture are not the same, it means that the grayscale value of the pixel of the ink screen when displaying the Nth historical picture has changed, and the comparison is stopped. Then, the display time of the pixel of the ink screen from the first historical picture to the N-1th historical picture is calculated, and the display time is the time during which the grayscale value of the pixel of the ink screen does not change.

其中，当所述墨水屏为黑白墨水屏时，所述第一极限灰度值可以为黑色灰度值，也可以为白色灰度值；当所述墨水屏为acep墨水屏(acep为Advanced Color ePaper的缩写）时，所述第一极限灰度值可以为某种原色的极限灰度值，现有的acep墨水屏一般产生八种原色，其中现有的一种acep墨水屏的八种原色包括白色、黑色、红色、绿色、蓝色、青色、黄色和品红色。Among them, when the ink screen is a black and white ink screen, the first limit grayscale value can be a black grayscale value or a white grayscale value; when the ink screen is an ACEP ink screen (ACEP is the abbreviation of Advanced Color ePaper), the first limit grayscale value can be a limit grayscale value of a certain primary color. The existing ACEP ink screen generally produces eight primary colors, among which the eight primary colors of an existing ACEP ink screen include white, black, red, green, blue, cyan, yellow and magenta.
本申请将所述墨水屏的像素点的灰度值复位至第一极限灰度值后，此时所述墨水屏的像素点进行复位刷新，然后再将所述墨水屏的像素点的灰度值从所述第一极限灰度值恢复至所述当前颜色参数值所对应的当前灰度值，从而保证所述墨水屏的像素点的实际颜色不失真。In the present application, after the grayscale value of the pixel points of the ink screen is reset to the first limit grayscale value, the pixel points of the ink screen are reset and refreshed, and then the grayscale value of the pixel points of the ink screen is restored from the first limit grayscale value to the current grayscale value corresponding to the current color parameter value, thereby ensuring that the actual color of the pixel points of the ink screen is not distorted.
请参考图8，图8为本申请提供的一种墨水屏的驱动方法的步骤S200的实施例二的流程图。进一步地，在图5所提供的驱动方法的基础上，所述对所述墨水屏的像素点的灰度值进行复位后再恢复至所述当前颜色参数值所对应的当前灰度值的步骤，包括：Please refer to FIG8 , which is a flow chart of step S200 of embodiment 2 of a method for driving an ink screen provided by the present application. Further, based on the driving method provided in FIG5 , the step of resetting the grayscale value of the pixel point of the ink screen and then restoring it to the current grayscale value corresponding to the current color parameter value includes:
步骤S203、将所述墨水屏的像素点的灰度值至少复位至一次第一极限灰度值和一次第二极限灰度值，所述第一极限灰度值和所述第二极限灰度值为不同灰度值；Step S203, resetting the grayscale value of the pixel point of the ink screen to at least one first limit grayscale value and one second limit grayscale value, wherein the first limit grayscale value and the second limit grayscale value are different grayscale values;
步骤S204、再将所述墨水屏的像素点的灰度值从所述第一极限灰度值或所述第二极限灰度值恢复至所述当前颜色参数值所对应的当前灰度值。Step S204: restore the grayscale value of the pixel of the ink screen from the first limit grayscale value or the second limit grayscale value to the current grayscale value corresponding to the current color parameter value.
其中，当所述墨水屏为黑白墨水屏时，所述第一极限灰度值可以为黑色灰度值或白色灰度值，第二极限灰度值可以为白色灰度值或黑色灰度值，所述第一极限灰度值和所述第二极限灰度值为不同灰度值；当所述墨水屏为acep墨水屏(acep为Advanced ColorePaper的缩写）时，所述第一极限灰度值可以为某种原色的极限灰度值，第二极限灰度值可以为另外一种原色的极限灰度值，现有的acep墨水屏一般产生八种原色，其中现有的一种acep墨水屏的八种原色包括白色、黑色、红色、绿色、蓝色、青色、黄色和品红色。Among them, when the ink screen is a black and white ink screen, the first limit grayscale value can be a black grayscale value or a white grayscale value, the second limit grayscale value can be a white grayscale value or a black grayscale value, and the first limit grayscale value and the second limit grayscale value are different grayscale values; when the ink screen is an ACEP ink screen (ACEP is the abbreviation of Advanced ColorePaper), the first limit grayscale value can be the limit grayscale value of a certain primary color, and the second limit grayscale value can be the limit grayscale value of another primary color. The existing ACEP ink screen generally produces eight primary colors, among which the eight primary colors of an existing ACEP ink screen include white, black, red, green, blue, cyan, yellow and magenta.
本申请将所述墨水屏的像素点的灰度值至少复位至一次第一极限灰度值和一次第二极限灰度值，因为只是将所述墨水屏的像素点的灰度值复位至一次第一极限灰度值，由于所述墨水屏的残影现象较严重，有可能所述墨水屏有些像素在复位至一次第一极限灰度值后还存在残影，因此需要对所述墨水屏的像素点的灰度值进行至少两次复位，也即是至少复位至一次第一极限灰度值和一次第二极限灰度值，此时所述墨水屏的像素点进行复位刷新，然后再将所述墨水屏的像素点的灰度值从所述第一极限灰度值恢复至所述当前颜色参数值所对应的当前灰度值，从而保证所述墨水屏的像素点的实际颜色不失真。The present application resets the grayscale value of the pixel points of the ink screen to at least once the first limit grayscale value and once the second limit grayscale value. Because the grayscale value of the pixel points of the ink screen is only reset to the first limit grayscale value once, and since the afterimage phenomenon of the ink screen is more serious, it is possible that some pixels of the ink screen still have afterimages after being reset to the first limit grayscale value once. Therefore, the grayscale value of the pixel points of the ink screen needs to be reset at least twice, that is, at least reset to the first limit grayscale value once and the second limit grayscale value once. At this time, the pixel points of the ink screen are reset and refreshed, and then the grayscale value of the pixel points of the ink screen is restored from the first limit grayscale value to the current grayscale value corresponding to the current color parameter value, thereby ensuring that the actual color of the pixel points of the ink screen is not distorted.
进一步地，在图1所提供的驱动方法的基础上，在本申请的一实施例中，所述获取所述墨水屏的像素点在显示当前显示画面时的当前颜色参数值以及在显示待显示画面时的目标颜色参数值的步骤，包括：Further, based on the driving method provided in FIG. 1 , in one embodiment of the present application, the step of obtaining the current color parameter value of the pixel point of the ink screen when displaying the current display screen and the target color parameter value when displaying the screen to be displayed includes:
同时获取至少两个所述墨水屏的像素点在显示当前显示画面时的当前颜色参数值以及在显示待显示画面时的目标颜色参数值，至少两个所述墨水屏的像素点在显示当前显示画面时的当前颜色参数值存储在同一个存储单元内，至少两个所述墨水屏的像素点在显示待显示画面时的目标颜色参数值存储在同一个存储单元内。At the same time, current color parameter values of at least two pixels of the ink screen when displaying the currently displayed screen and target color parameter values when displaying the screen to be displayed are obtained. The current color parameter values of at least two pixels of the ink screen when displaying the currently displayed screen are stored in the same storage unit, and the target color parameter values of at least two pixels of the ink screen when displaying the screen to be displayed are stored in the same storage unit.
鉴于目前主流计算机设备均为64位或32位的操作系统，而计算机设备的字长是指计算机进行一次整数运算所能处理的二进制数据的位数，计算机设备的字长是由CPU的类型所决定，不同的计算机设备的字长是不同的，常见的有8位、16位、32位、64位等，字长越长，计算机设备一次处理的二进制数据的位数就越多，精度就越高。而大多数电子墨水屏处理一个像素的数据一般需要8位字长或16为字长。Given that the current mainstream computer devices are all 64-bit or 32-bit operating systems, and the word length of a computer device refers to the number of bits of binary data that the computer can process in an integer operation, the word length of a computer device is determined by the type of CPU, and the word lengths of different computer devices are different. Common ones are 8-bit, 16-bit, 32-bit, 64-bit, etc. The longer the word length, the more bits of binary data the computer device can process at one time, and the higher the accuracy. Most electronic ink screens generally require 8-bit or 16-bit word lengths to process data for one pixel.
而本申请通过同时获取至少两个所述墨水屏的像素点在显示当前显示画面时的当前颜色参数值以及在显示待显示画面时的目标颜色参数值，也即是同时处理至少两个所述墨水屏的像素点的颜色参数值，并且至少两个所述墨水屏的像素点在显示当前显示画面时的当前颜色参数值存储在同一个存储单元内，至少两个所述墨水屏的像素点在显示待显示画面时的目标颜色参数值存储在同一个存储单元内，因此等于一次指令能处理多个像素的数据，有利于提高数据处理的速度，从而提高所述墨水屏的画面刷新速度。The present application simultaneously obtains the current color parameter values of at least two pixels of the ink screen when displaying the currently displayed screen and the target color parameter values when displaying the screen to be displayed, that is, simultaneously processes the color parameter values of at least two pixels of the ink screen, and the current color parameter values of at least two pixels of the ink screen when displaying the currently displayed screen are stored in the same storage unit, and the target color parameter values of at least two pixels of the ink screen when displaying the screen to be displayed are stored in the same storage unit. Therefore, one instruction can process data of multiple pixels, which is beneficial to improve the speed of data processing, thereby improving the screen refresh speed of the ink screen.

If so, first historical waveform data corresponding to the first historical color parameter is obtained, and the first historical waveform data is a driving waveform sequence for the pixel points of the ink screen. Otherwise, the driving waveform sequence for the pixel points of the ink screen is obtained according to the current color parameter value and the target color parameter value, thereby reducing the calculation workload of the driving waveform sequence and improving the image refresh speed of the ink screen.
