Hardware solution for Vestel Electronics to export to 156 countries around the world. Screens up to 65 inches. 4K video resolution. V-by-One/LVDS and many other interfaces.

The software platform — Android (AOSP) — was provided by AMLogic.

Android-based TV for Digital Signage

Project in a Nutshell: For Vestel Electronics, a major TV manufacturer exporting to 156 countries, Promwad ran the bring-up and system integration of an Android-based digital-signage TV on an AMLogic T962X3 SoC (49 to 65-inch 4K, HDMI, DisplayPort, USB-C, OPS, V-by-One/LVDS) running Android Pie. Promwad customized the Android apps, added backlight-based energy saving, touchscreen and rotation support, and OPS device support for interactive panels and video walls.

Client

Vestel Electronics is a popular manufacturer of home and professional appliances. It is a holding of 18 companies that specialise in electronics, major appliances, and TV solutions. Vestel devices are available in 2,500 retail stores around the world.

Challenge

Our goal was to help the customer with the bring-up and system components integration.

Together with the client, we participated in both solution architecture and software development. Here are some examples of our project tasks:

Customization of standard Android apps according to the customer's business logic.
Implementation of energy-saving algorithms based on backlight level change depending on the input video signal.
Development of additional system services to provide access to system/hardware resources.
Touchscreen support integration + device rotation support.
Help the customer develop UI applications + third-party application integration.
Improvements to the update system and remote control integrations.
Support for OPS device (Open Pluggable Specification) and RTC + power mode control.

Solution

We have addressed all the client's engineering challenges. Below you can find a detailed description of the design products and the stages of the project.

The Android-based TV will be used as an interactive flat-panel display (IFPD) or a video wall in the digital signage market.

1. Hardware design

The hardware platform is AMLogic SoC for TV devices (T962X3). Its key features:

screens sizes: 49, 55, 65 inches with 4K video resolution;
HDMI1-4, DisplayPort, USB Type-C, OPS + V-by-One/LVDS interfaces;
touchscreen and accelerometer.

2. Software development

The device runs Android Pie (9.0). The AOSP code version was provided by AMLogic with their T962X3 support.

Business Value

We helped our client to design a new product for the digital signage market and equip it with the software and hardware features the Vestel company needs to make it stand out from the competitors: touchscreen support integration, various remote control integrations, OPS device support, and more. Our customer's products are successfully exported to 156 countries around the world, thanks to the constant incorporation of the latest technology into their designs.
