Description
Technical Field
The present invention relates to the field of electronic devices, and in particular, to a refresh control method, a storage medium, and a device for an electronic ink screen.
Background
The electronic ink screen is a technology for innovating information display, and can enable the screen to display the general effect of paper. The ghost is a difficulty that it has been difficult to overcome. Multiple swipes often result in contours of previously displayed patterns on the electronic ink screen, resulting in a poor reading experience. The reason is that the display content of a single point of the electronic ink screen is interfered by adjacent points, so that only a distinguishing part between two frames of images is refreshed, and a part which is unchanged is not affected, and the result is that black ink is different in black degree, white ink is not completely white, and afterimages appear.
The method commonly adopted in the handheld device of the electronic ink screen at present is that GC full screen refreshing is combined with GU common refreshing, for example, GC full screen refreshing is carried out once after the fixed page number is turned over in each GU common refreshing mode so as to eliminate the residual shadow, so that a comprehensive balance of display effect and switching effect is obtained. But this strategy of GC full screen refresh combined with GU normal refresh can only be directed to full screen reading. In addition, some simple mechanisms for directly determining the current GC full screen refresh or GU common refresh according to the screen area of the brush screen are not strong enough in universality. In the occasion that electronic ink screens are increasingly facing rich applications, a strategy of controlling GC full screen refreshing and GU common refreshing under complex screen content refreshing actions becomes an important point. Therefore, a refresh control method and a refresh control system for an electronic ink screen are needed, so that GC full-screen refresh and GU common refresh can be reasonably controlled, and applicability is improved.
The refresh control method and system of the electronic ink screen proposed by the chinese patent application CN102509526a propose that dynamic refresh is realized according to the percentage of the minimum rectangular area of the content change area occupying the whole screen, which can be realized to a certain extent, but the scheme has various drawbacks, because the scheme only relies on the area to calculate, if two interfaces are switched interactively, no matter how many times the two interfaces are switched, full screen refresh will not be triggered, but the more the ghost is actually accumulated.
