Let’s start by getting to know the merits of webOS Signage.
Merits of webOS Signage
webOS Signage is a web-based platform and provides an execution environment for web apps.
These "one-source multi-use" HTML5-based apps can run on any platform or device, and you can access your content directly from any device with an internet connection.
webOS Signage improves your experience through intuitive Launcher and Smart Home. Launcher provides a convenient and user-friendly experience to make apps executed simply and easily.
Also, webOS OSD (On Screen Display) is designed more freshly and compared to existing Signage products.
For more information on the Launcher and Smart Home UI, see User Interface.

Only contracted partner developers with DA (Development Agreement) can download SDK, read technical documents, and use partner forums in this developer site.
webOS Signage Architecture
webOS Signage is based on webOS that is specialized for signage display. You can develop web apps using the SCAP library along with a web app framework such as jQuery. SCAP library allows your web app to control the device or get information from the webOS Signage resources. The following diagram illustrates the webOS Signage architecture.
The key components of webOS Signage are described below:
The SCAP (Signage Common Application Platform) library provides functions for managing device settings, hardware resources, and web apps. For more information, see SCAP API.
|Harmony Library||The Harmony library provides a set of APIs to control the add-on sensors on the webOS Signage device. For more information, see Harmony API.|
|CustomJS Library||The CustomJS library provides useful APIs to manage and control your app as well as the webOS Signage features. For more information, see CustomJS API.|
|Luna Bus||Luna Bus is a system bus that supports the IPC mechanism used for interaction between webOS Signage components.|
