Mainly there is three modes are used in Display
Fullscreen
Opens the web application without any browser UI and takes up the entirety of the available display area.
Standalone
Opens the web app to look and feel like a standalone native app. The app runs in its own window, separate from the browser, and hides standard browser UI elements like the URL bar, etc.
Minimal-ui
This mode is similar to fullscreen, but provides the user with some means to access a minimal set of UI elements for controlling navigation (i.e., back, forward, reload, etc).
Note: Only supported by Chrome on mobile.
