webOS Signage is a web-centrist platform that powers the LG Digital Signage. It is developer-friendly and provides powerful features for you to leverage for creating features in rich web apps. Best of all, webOS Signage is compatible with the programming languages and technologies you are already familiar with, like HTML, JavaScript, CSS, and more, so you can choose the way you want to develop.

Let’s start by getting to know the merits of webOS Signage.

Web-Centrist Platform

A figure that webOS Signage is a web-centric platform.

webOS Signage is a web-based platform and provides an execution environment for web apps.

The platform supports cross-browser, which means that you can build web-based apps in HTML5, CSS, and JavaScript while saving time and labor costs.

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.

Intuitive UX

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.

App Deployment Scenarios

webOS Signage allows various app deploying scenarios. Developers can choose the appropriate scenario according to their situation.

– Local Storage Deploying Scenario: Launches a web app from local storage. You should deploy the app with a web server or USB storage.

– USB storage Deploying Scenario: Runs a web app directly from USB storage attached to your computer.

– Remote Server Deploying Scenario: Runs a web app from a remote server.

For more information, see Deploying Your App.

Developing without Fuss

You can use our SDK and get technically supported fully from the LG Signage Support team when developing apps on webOS Signage.

Our developer website provides webOS Signage SDK download, technical documents, forums to make customers develop their apps in a more convenient environment.

The SDK includes the SCAP library and documents that can be used to develop your apps for webOS Signage.

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:

Web App	The web app on webOS Signage is developed using HTML5, CSS, JavaScript, JavaScript libraries (e.g., jQuery), UI framework (e.g., Bootstrap), and webOS Signage libraries (e.g., SCAP API).
JS Service	The JavaScript (JS) service on webOS Signage provides a way for apps to work even when they are not running. The service also allows the platform feature, which usually restricts access to apps, to access them.
SCAP Library	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.
webOS Signage Platform	A set of resources that are designated for running webOS Signage device.
