Abstract

The invention provides a visible window synthesis method and device and a multi-screen system. The synthesis method comprises the following steps: determining a plurality of target visible windows under the condition that a plurality of first visible windows are displayed on at least two display screens, wherein the total number of the target visible windows on all the display screens is smaller than the total number of the first visible windows on all the display screens; and synthesizing the plurality of target visible windows in one display screen to form at least one second visible window. According to the visible window synthesis method, only part of the first visible windows is synthesized, the resource consumption of a CPU and a GPU is reduced, the consumed time for synthesizing a layer is shortened, the system jamming phenomenon is relieved, and the problem that jamming is prone to occurring in a synthesis method of the first visible windows in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of window composition, and in particular, relates to a method for synthesizing a visible window, a synthesis device, a computer-readable storage medium, a processor, and a multi-screen system. Background technique [0002] Now a car device can support multiple screens to provide users with more personalized operations and display more content. [0003] When an in-vehicle device supports multiple screen displays, the number of application windows visible in the foreground and the number of application windows cached in the background of the android system of the in-vehicle device will increase. The first visible window and the background cache window, and synthesize the first visible window of all screens on the CPU and / or GPU, which will increase the consumption of resources such as CPU and GPU, and increase the synthesis time of the surfaceflinger process, exceeding 16.6ms, causing The system fre...
