The Graphics subsystem mainly consists of user interface \(UI\) components, layout, animator, font, input event, window management, and rendering and drawing modules. It is an application framework that can be built on the LiteOS to develop HarmonyOSOpenHarmony applications for Internet of Things \(IoT\) devices with limited hardware resources or on the standard OS to develop HarmonyOSOpenHarmony applications for standard- and large-system devices \(for example, tablet and lite smart devices\).
