Embodiment Construction

[0055] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.

[0056] Before introducing the plan, first introduce the process of regional merger.

[0057] The merging of multiple regions can also be regarded as the union of multiple regions, and the merged region obtained by merging multiple regions is the smallest region surrounding the multiple regions.

[0058] As for the video terminal, the window area is generally rectangular, so the area after multiple rectangular areas is merged is the smallest rectangular area...

Abstract

This application discloses a screen refresh system and method. This application divides multiple windows into multiple groups in advance according to the neighbor relationship of the window area. The window applications corresponding to the windows in each group form a window application group. Multiple window application groups The window management system only determines one target window application group from multiple window application groups in each time period, and sends time slices to each target window application in the target window application group, and the window application only receives After the time slice is reached, only when it is detected that the screen needs to be refreshed within the time slice length can it interact with the window management system to realize screen refresh. That is, within a period of time, at most only one window application in a window application group can refresh the screen, and the window areas corresponding to each window application in the same window application group are relatively close, even if the areas are merged, it will not cause excessive Drawing not necessary.

Description

Technical field [0001] This application relates to the field of screen refresh technology, and more specifically, to a screen refresh system and method. Background technique [0002] The screen of the terminal corresponds to a frame buffer in the system. The frame buffer is a pre-allocated buffer memory in which the pixel content to be displayed is stored. The bottom layer generally provides an interface to display the content in the frame buffer on the terminal screen. [0003] Multiple windows can exist on the terminal screen at the same time, and operations such as refreshing, drawing, and screen loading of multiple windows are managed by the window management system. The window management system provides a unified refresh interface to the outside, and any window can notify the window management system to refresh the specified area (usually the area occupied by the window) through this refresh interface. For the window management system, the area is rectangular. The window ma...
