Description
Technical Field
The invention relates to the technical field of ink screens, in particular to a refreshing control method, a refreshing control storage medium and refreshing control equipment of an electronic ink screen.
Background
The electronic ink screen is an innovative information display technology, and can display the common effect of paper. Ghosting is a difficult point which has been difficult to overcome. Multiple swipes often result in a previously displayed outline of the image on the electronic ink screen, resulting in a poor reading experience. The reason for this is that the display content of a single dot of the electronic ink screen is interfered by adjacent dots, and thus it is impossible to refresh only a portion differentiated between two frames of images without affecting an unchanged portion, which results in a difference in black level of black ink, and a residual image due to the fact that some white ink is not completely white.
At present, the mode commonly adopted in handheld equipment of an electronic ink screen is that GC full screen refreshing is combined with GU ordinary refreshing, for example, after a fixed number of pages are turned by using a GU ordinary refreshing mode, GC full screen refreshing is carried out once to eliminate residual shadows so as to obtain a comprehensive balance of a display effect and a switching effect. However, the strategy of combining GC full screen refresh and GU normal refresh is only applicable to full screen reading. In addition, some simple mechanisms directly determine the current GC full-screen refreshing or GU normal refreshing according to the refreshing area are not strong enough in universality. In the situation that the electronic ink screen is more and more rich in application, how to combine the strategy of GC full-screen refresh and GU normal refresh under the complex screen content refresh action becomes an important point. Therefore, a refresh control scheme of the electronic ink screen is needed, GC full screen refresh and GU common refresh can be reasonably controlled, and applicability is improved.
Disclosure of Invention
In view of the deficiencies of the prior art, the present invention is directed to a refresh control method, a storage medium and an apparatus for an electronic ink screen.
In order to achieve the purpose, the invention adopts the following technical scheme:
a refresh control method of an electronic ink screen comprises the following specific processes:
s1, dividing a display area of the electronic ink screen into M rows and N columns of grids, wherein each grid block is rectangular;
s2, acquiring and storing the coordinate data of each grid block;
s3, after the interface content of the electronic ink screen is refreshed each time, comparing the refreshed content in each grid block with the refreshed content in the last time according to the coordinate data of each grid block, acquiring the number of grid blocks with changed content, and calculating the proportion of the grid blocks with changed content in the total number of the grid blocks;
s4, carrying out GU refreshing on the grid blocks with changed contents, and updating the global refreshing count value according to the ratio value obtained in the step S3; the global refresh count value after each update is unchanged or increased progressively relative to the global refresh count value before the update;
and S5, when the global refresh count value is larger than or equal to a preset global refresh threshold value, triggering the global refresh of the electronic ink screen, and after the global refresh, restoring the global refresh count value to an initial value.
Further, the GU refreshing times of each grid block are counted separately, and if the GU refreshing times of a certain grid block exceed a preset refreshing threshold, the grid block is triggered to refresh in the GC mode.
Further, in step S4, the process of updating the global refresh count value is as follows: different ratio intervals map different counting steps, and when the ratio calculated in step S3 falls into a certain ratio interval, the current global refresh count value is added to the counting step mapped by the ratio interval to obtain the latest global refresh count value.
Further, in step S4, the process of updating the global refresh count value is as follows: and calculating the latest global refresh count value according to a preset linear increasing mode with positive correlation.
The invention also provides a computer-readable storage medium having stored therein a computer program which, when executed by a processor, implements the above-described method.
The invention also provides an electronic device with an electronic ink screen, comprising a processor and a memory, wherein the memory is used for storing a computer program; the processor is configured to implement the above method when executing the computer program.
The invention has the beneficial effects that: by utilizing the method and the device, the partition refreshing control can be carried out on the display area of the ink screen, the combination of GC full-screen refreshing and GU common refreshing is carried out in a targeted manner, the ghost shadow and the screen flash are reduced, and the user experience is improved.
Detailed Description
The present invention will be further described below, and it should be noted that the present embodiment is based on the technical solution, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides a refresh control method of an electronic ink screen, which specifically comprises the following processes:
s1, dividing a display area of the electronic ink screen into M rows and N columns of grids, wherein each grid block is rectangular;
m, N is a positive integer greater than 1. M, N may be a default value or may be user-defined. In addition, if the values of M and N are too small, the grid division is small, the content change error obtained by each grid block is large, and the greater the value of M, N is, the more accurate the refresh effect is, but the power consumption may be relatively large. Therefore, the user-set values of M and N may be prohibited from exceeding the maximum and minimum thresholds by presetting M, N the maximum and minimum thresholds.
And S2, acquiring and storing the coordinate data of each grid block. Specifically, the coordinates of the upper left corner of each grid block are acquired as corresponding coordinate data.
S3, after the interface content of the electronic ink screen is refreshed each time, comparing the refreshed content in each grid block with the refreshed content in the last time according to the coordinate data of each grid block, acquiring the number of grid blocks with changed content, and calculating the proportion value of the grid blocks with changed content in the total number of the grid blocks;
s4, GU refreshing the grid blocks with changed content, and updating the global refresh count value according to the ratio value obtained in the step S3; the global refresh count value after each update is either unchanged or incremented relative to the global refresh count value before the update.
In this embodiment, as a calculation method, different duty value intervals map different counting steps, and when the duty value calculated in step S3 falls into a certain duty value interval, the current global refresh count value is added to the counting step mapped by the duty value interval to obtain the latest global refresh count value.
Alternatively, the latest global refresh count value may be calculated in a preset linear increasing manner with positive correlation.
S5, when the global refresh count value is larger than or equal to the preset global refresh threshold value, triggering the global refresh of the electronic ink screen, and after the global refresh, the global refresh count value is restored to the initial value (which can be 0 or other values.)
In this embodiment, the GU refresh times of each grid block are counted separately, and if the GU refresh times of a certain grid block exceed a preset refresh threshold, the grid block is triggered to refresh in the GC mode.
Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
