Description
Technical Field
The invention relates to the field of electronic books, in particular to a refreshing display method of ink screen equipment, electronic equipment and a storage medium.
Background
When the ink screen equipment refreshes the screen, the driving waveform corresponding to each pixel point in the gray image to be displayed is searched in a preset table according to the gray value of the pixel point. And driving the ink capsules corresponding to the pixel positions on the ink screen equipment according to the driving waveforms obtained by looking up the table to enable the black and white particles in the ink capsules to move at different distances so as to form corresponding gray scale colors. The whole table look-up process is called LUT (look-up table). The driving waveform (waveform) includes information of voltage, pulse number, pulse duration, and the like. When looking up the table, the parameters such as screen temperature and the like are also referred (the display characteristics of the ink screen equipment are different at different temperatures, and the driving waveforms of all gray scales at all temperatures are recorded in the table).
There are various refresh modes of the ink screen device, and common modes include modes such as a2, DU, GL16, GC16, and the like. As shown in fig. 1, different refresh modes, performances, etc. under different application scenarios are included. For example, in video animation playing and web page browsing scenes, an a2 refresh mode is adopted for fast refresh display, a DU refresh mode is adopted for handwriting application, and refresh modes such as GL16 and GC16 are applied to common reading scenes. The time consumed by each mode refresh is mainly in the table look-up process (i.e. LUT) of the driving waveform of the ink screen device, and the main difference of each refresh mode is that the frame (frame) number of the LUT of each mode is different, while the electric particles of the ink screen device move at 85Hz FPS (Frames Per Second, transport frame number Per Second), and each frame electric particle moves for 11.76ms, taking a2 refresh mode as an example, under the condition of a temperature of 25 ℃, 120ms is required for completing one refresh, i.e. 120ms is required for the ink screen device to refresh and display one picture. Under the occasions of rapid change of pictures such as video playing, webpage browsing and the like, the image refreshing rate of the ink screen device 8FPS can cause very unsmooth bad experience for users, and the refreshing rate of the ink screen is urgently needed to be improved, so that the smoothness of the pictures is improved.

Detailed Description
Example one
FIG. 2 is a flow chart illustrating a refresh display method of an ink screen device according to an embodiment of the present invention, as shown in FIG. 2, the method includes the following steps:
in step S201, a current refresh mode of the ink screen device is determined.
The present embodiment is implemented based on a frame-down refresh command that is predefined and stored. The frame-reducing refresh command achieves an increase in refresh rate by reducing the number of frames refreshed. Specifically, for example, under the condition of 25 ℃, taking an a2 refresh mode as an example, about 10 frames (corresponding to a refresh time of 120 ms) of movement are required for completely displaying the electric particles of an ink screen of a picture, and if the electric particles move each frame, the consumed time can be shortened by 11.76ms, so that the refresh speed of the ink screen device is increased, the pause under the situation of rapid change of the picture is improved, the smoothness is improved, if the movement of the electric particles of two frames is reduced, the corresponding image refresh rate can reach 10FPS, and the picture smoothness can be remarkably improved.
Before invoking the frame-reducing refresh command, it is also necessary to determine the current refresh mode of the ink screen device in order to determine whether the frame-reducing refresh command is applicable. When the current refresh mode of the ink screen device is determined, the corresponding current refresh mode may be determined according to a change of a current scene of the ink screen device, or the current refresh mode corresponding to a change caused by an operation may be determined according to a trigger operation of a user, or the like. Specifically, if in the reading mode, the user clicks a video playing button to watch video playing, or the user starts to browse a webpage, the ink screen device automatically changes the refresh mode, such as switching from the GC16 refresh mode to the a2 refresh mode; alternatively, in the reading mode, when the user writes on the screen using the stylus, the ink screen automatically changes the refresh mode, such as switching from the GC16 refresh mode to the DU refresh mode, and so on, to determine the current refresh mode.
Step S202, according to the current refresh mode and/or user operation, judging whether the frame-reducing refresh processing condition is satisfied.
The predefined and stored frame-reducing refresh command includes at least one frame-reducing refresh command corresponding to the refresh mode. The frame reduction refresh command corresponds to a refresh mode, and different refresh modes correspond to different frame reduction refresh commands. After the current refresh mode is determined, when it is determined whether it meets the frame-reduction refresh processing condition, it is determined whether the current refresh mode is a refresh mode included in the frame-reduction refresh command, if so, it is determined that the frame-reduction refresh processing condition is met, and step S203 may be executed; if not, no frame-reducing refreshing instruction corresponding to the current refreshing mode exists, and refreshing processing is executed according to the current refreshing mode.
Further, when the specific judgment is carried out, when the refresh mode switching is detected, the video browsing is converted from the character reading, the refresh mode is switched, whether the switched current refresh mode is the appointed refresh mode or not is judged, and if yes, the frame-reducing refresh processing condition is judged to be met. Or when detecting that the appointed refresh mode triggered by the third-party application program starting is adopted as the current refresh mode, judging that the frame-reducing refresh processing condition is met. If a third-party application program is opened, a specified refresh mode is triggered, and the like; or, a preset operation entry is set in advance for a user, the preset operation entry is a preset call entry for frame reduction refresh processing, and the user may directly operate the corresponding preset operation entry, preferably, the preset operation entry is a virtual operation entry of a graphical user interface of the ink screen device or an entity operation entry of the ink screen device, such as a touch button or an entity button of the graphical user interface, for example, an extremely fast refresh button, a fast handwriting button, and the like, so that the user may directly operate when browsing a webpage, watching a video, and the like. And when the triggering operation of the user on the preset operation entrance is detected, judging that the frame-reducing refreshing processing condition is met. Further, after the user triggers the operation on the preset operation entry, the current refresh mode may also relate to different modes, and it is further required to determine whether the current refresh mode is the designated refresh mode, and if so, it is determined that the frame-reducing refresh processing condition is met.
Here, the specified refresh mode corresponds to a frame-down refresh command defined and stored in advance. The frame-reducing refreshing instruction comprises at least one frame-reducing refreshing instruction corresponding to the refreshing mode. Considering that different refresh modes, such as GC16 and GL16, take too long time and are not suitable for situations requiring timely refresh feedback, such as handwriting, web browsing, video playing, etc., even if the effect of calling the frame-reducing refresh command for improvement cannot meet the requirements of the situations. Therefore, the present embodiment defines and stores the frame-down refresh command in advance for specifying the refresh mode. And the frame-reducing refreshing instruction is a frame-reducing refreshing instruction corresponding to the specified refreshing mode. The specified refresh modes include, for example, a2 refresh mode or DU refresh mode, and these refresh modes with faster refresh rates are suitable for the reduced frame refresh command.
Step S203, a frame-reducing refresh command is called for the display control module to execute frame-reducing processing when the display control module performs refresh display in the current refresh mode after receiving the frame-reducing refresh command.
When step S202 is executed and it is determined that the frame-reducing refresh processing condition is met, a frame-reducing refresh command corresponding to the current refresh mode may be called, and after the frame-reducing refresh command is received by the display control module of the ink screen, the frame-reducing processing is performed when a waveform driving look-up table (LUT) is executed on the basis of performing refresh display according to the current refresh mode, thereby improving the refresh efficiency.
The frame-dropping refresh command specifically includes, for example, a frame-skipping refresh command or a frame-dropping refresh command. The frame skipping refresh command is to skip some frames to perform refresh during refresh, for example, only 1, 3, 5, 7, 9 single frames are refreshed during table look-up of driving waveforms, and double frames are not refreshed; the frame-dropping refresh command can drop some frames and does not refresh, for example, the original 10 frames need to be refreshed, the frame-dropping refresh command only refreshes the previous 8 frames, and the last 2 frames are omitted and do not refresh. When the number of frames to be refreshed and the frame-reducing mode (which frames to be refreshed are reduced) in the frame-reducing refreshing instruction can be defined in advance, the frame-reducing mode configuration information, the frame-reducing number configuration information and the like are packaged in the frame-reducing refreshing instruction, and the specific setting needs to take the refreshing speed and the refreshing effect into consideration to configure appropriate information. The above is an example to illustrate that, during specific processing, a suitable frame is selected according to an implementation situation to perform a frame skipping refresh command or a frame dropping refresh command.
When the frame reducing processing is executed, the corresponding frame reducing processing is executed according to the frame reducing mode configuration information and the frame reducing quantity configuration information corresponding to the frame reducing refreshing instruction, so that the refreshing speed is improved, the refreshing effect is guaranteed, and good use experience is provided for users.
According to the refresh display method of the ink screen equipment, the frame reduction processing is executed on the current refresh mode and/or user operation which accord with the frame reduction refresh processing conditions based on the frame reduction refresh command, the processing speed of the refresh mode is improved, the picture displayed by the ink screen equipment is smoother, and the user experience is improved.
Example two
Fig. 3 is a flow chart illustrating a refresh display method of an ink screen device according to another embodiment of the present invention, as shown in fig. 3, the method includes the following steps:
step S301, determining the current refresh mode of the ink screen device.
Step S302, according to the current refresh mode and/or user operation, judging whether the frame-reducing refresh processing condition is satisfied.
The above steps refer to the descriptions of steps S201 to S202 in the first embodiment, and are not described again here.
When it is judged that the frame reduction refresh processing condition is satisfied, step S303 is executed.
Step S303, a shake compensation process is performed on the image to be displayed.
Specifically, in consideration of the fact that after the frame reduction processing is performed, the image may appear blurred and have serious afterimage, and in order to alleviate the occurrence of such a situation and improve the display effect, when the step S302 is performed to determine that the frame reduction refreshing processing condition is met, and the frame reduction processing is performed, the image to be displayed is subjected to the shake compensation processing. By employing an image shake compensation algorithm, such as the Dither shake compensation algorithm, the image is processed before the drive waveform look-up table (LUT) is performed. Considering that the image transmitted to the display control module in the refresh modes of DU, a2, etc. is a binary image (corresponding to the gray level 0/15), when the image to be displayed is subjected to the image dithering compensation process by using the image dithering compensation algorithm and then the frame reduction process is performed, a better image presentation effect can be achieved.
Optionally, since the image dithering compensation algorithm, such as the gather dithering compensation algorithm, needs a certain time for operation in the CPU, in order to reduce the time consumption, the gather dithering compensation algorithm may be moved to the GPU, and the GPU is used to perform high-speed parallel operation, so as to implement the dithering compensation processing on the image to be displayed, thereby increasing the operation speed.
Step S304, a frame-reducing refreshing instruction is called for the display control module to execute frame-reducing processing when the display control module adopts the current refreshing mode to refresh the display after receiving the frame-reducing refreshing instruction.
After the image to be displayed is subjected to jitter compensation processing, a frame reduction refreshing instruction is called, and after the frame reduction refreshing instruction is received by the display control module, frame reduction processing is executed when refreshing display is carried out in a current refreshing mode, so that the refreshing speed is improved.
According to the refresh display method of the ink screen equipment, provided by the invention, before the frame reduction processing is executed, the jitter compensation processing is carried out on the image to be displayed, so that the problems of image jitter, ghost image, trailing and the like are avoided, and the whole image is clearer and smoother.
EXAMPLE III
FIG. 4 is a flow chart illustrating a refresh display method of an ink screen device according to another embodiment of the present invention, as shown in FIG. 4, the method includes the following steps:
in step S401, the current refresh mode of the ink screen device is determined.
Step S402, according to the current refresh mode and/or user operation, judging whether the frame-reducing refresh processing condition is satisfied.
The above steps refer to the descriptions of steps S201 to S202 in the first embodiment, and are not described again here.
When it is judged that the frame reduction refresh processing condition is satisfied, step S403 is executed.
Step S403, determining whether the current application scene is the set application scene.
The operating system of the ink screen device may set a refresh frame rate, such as 60 frames, for the display. Changing the refresh frame rate of the operating system of the ink screen device will also correspondingly affect the refresh rate of the current refresh mode.
The ink screen device can display different application scenes, and when the number of the rendering overlay images displayed in the application scenes is small, the refresh frame rate of the operating system can be adjusted to improve the refresh speed of the refresh mode. Before adjusting the refresh frame rate of the operating system, it is also necessary to first determine whether the current application scenario is a set application scenario. Setting the application scene as a scene in which the number of the currently displayed rendering overlay graphs is less than a predetermined number, such as a handwriting mode scene or a partial video animation display scene.
Specifically, whether the current application scene is the set application scene may be determined according to information such as a currently displayed screen and a displayed content element of the ink screen device, and if yes, step S404 is executed. If not, the step S405 may be directly executed without adjusting the refresh frame rate of the operating system.
And step S404, dynamically adjusting the display refresh frame rate of the operating system according to the set application scene.
When the current application scene is judged to be the set application scene, and the display refresh frame rate of the operating system is dynamically adjusted, the display refresh frame rate of the operating system is improved, for example, from 60 frames to 90 frames, so that the display frame loss is avoided, and the refresh speed is further improved. When the refresh frame rate is displayed on the operating system, dynamic adjustment is performed, for example, a Vsync mechanism of an android operating system is dynamically adjusted by setting a configuration file, so that the CPU or GPU rendering overlay is accelerated, and the refresh speed is improved. Preferably, the display refresh frame rate of the operating system is dynamically adjusted by utilizing the efficient parallel operation of the GPU, so that the operation speed is higher.
Further, while dynamically adjusting the display refresh frame rate of the operating system, it is also necessary to monitor whether the current application scene is the set application scene in real time, and when the current application scene of the ink screen device changes, such as the current application scene exits, and the current application scene of the ink screen device is not the set application scene, the dynamic adjustment is stopped, such as the GPU is stopped to continue running the configuration file, the display refresh frame rate of the operating system is recovered, and the display refresh frame rate of the operating system is recovered to be normal.
Step S405, a frame-reducing refreshing instruction is called for the display control module to execute frame-reducing processing when the display control module adopts the current refreshing mode to refresh and display after receiving the frame-reducing refreshing instruction.
After the frame rate of the display refresh of the operating system is dynamically adjusted, a frame-reducing refresh command is called, and after the frame-reducing refresh command is received by the display control module, frame-reducing processing is executed when the display is refreshed in a current refresh mode, so that the refresh speed is improved.
According to the refresh display method of the ink screen device, provided by the invention, before the frame reduction processing is executed, whether the current application scene is the set application scene or not is judged, the display refresh frame rate of the operating system is dynamically adjusted according to the set application scene, the display refresh frame rate is increased, and the refresh rate is increased together with the frame reduction processing on the basis of avoiding the display frame loss, so that the picture display is smoother.
Example four
FIG. 5 is a flow chart illustrating a refresh display method of an ink screen device according to another embodiment of the present invention, as shown in FIG. 5, the method includes the following steps:
step S501, determining the current refresh mode of the ink screen device.
Step S502, according to the current refresh mode and/or user operation, judging whether the frame-reducing refresh processing condition is satisfied.
The above steps refer to the descriptions of steps S201 to S202 in the first embodiment, and are not described again here.
When it is judged that the frame reduction refresh processing condition is satisfied, step S503 is executed.
In step S503, a shake compensation process is performed on the image to be displayed.
Before refreshing and displaying in the current refreshing mode, the GPU is used for carrying out jitter compensation processing on an image to be displayed, so that the conditions of blurring, serious afterimage and the like are relieved.
Step S504, determine whether the current application scenario is the set application scenario.
And step S505, dynamically adjusting the display refresh frame rate of the operating system according to the set application scene.
And when the current application scene is judged to be the set application scene, the display refreshing frame rate of the operating system is improved, and the frame rate is improved so as to accelerate the refreshing speed. Setting the application scene as a handwriting mode scene or a scene with less than a preset number of rendering superimposed images such as a local video animation display scene, and after the display refresh frame rate of the operating system is increased, the operating system can normally process the scene to ensure normal display.
After the current application scene exits from the set application scene, if the application scene with more layers is in the rendering overlay, it is time-consuming, and here, when the display refresh frame rate of the operating system continues to maintain a higher frame rate, the system load is increased, normal display is affected, the display refresh frame rate of the operating system is recovered, and the display refresh frame rate of the operating system is recovered to be normal.
Step S506, a frame-reducing refresh command is called for the display control module to execute frame-reducing processing when the display control module performs refresh display in the current refresh mode after receiving the frame-reducing refresh command.
After the steps S503 to S505 are executed, the frame-reducing refresh command is called, and after the frame-reducing refresh command is received, the display control module executes frame-reducing processing when performing refresh display in the current refresh mode, so as to increase the refresh rate.
The execution sequence of step S503 and steps S504 to S505 is not limited herein, and the execution sequence may be set according to the implementation situation.
According to the refresh display method of the ink screen equipment, provided by the invention, before frame reduction processing is executed, the jitter compensation processing is carried out on an image to be displayed, the problems of image jitter, ghost image, tailing and the like are avoided, the display refresh frame rate of an operating system can be dynamically adjusted according to a set application scene, the display refresh frame rate is increased, and the refresh rate is increased together with the frame reduction processing on the basis of avoiding frame loss of display, so that the image display is clearer and smoother.
