| Graphics | 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 OpenHarmony applications for Internet of Things (IoT) devices with limited hardware resources or on the standard OS to develop OpenHarmony applications for standard- and large-system devices (for example, tablet and lite smart devices). | All systems |
| Driver | Constructed using the C object-oriented programming (OOP) language. It provides a unified driver platform and is compatible with different kernels by means of platform decoupling and kernel decoupling. This unified driver platform is designed to provide a more precise and efficient development environment, where you develop a driver that can be deployed on different systems supporting Hardware Driver Foundation (HDF). | All systems |
