Product Features
Product Overview
The ViewSonic LDM231-251 is a massive 231-inch All-in-One Direct View LED display designed for high-impact collaboration and digital signage in large venues. This integrated solution combines a professional-grade 4K UHD LCD panel with a built-in Rockchip RK3399 compute module, eliminating the need for external media players or PCs. Its direct-view LED backlight technology delivers 600 cd/m² brightness and wide 170-degree viewing angles, ensuring clear visibility even in brightly lit environments.
Engineered for permanent installation, the display features an ultra-narrow 0.24-inch bezel for a seamless multi-screen canvas. The integrated Android 9.0 operating system provides a familiar platform for app deployment, content management, and wireless screen sharing. With 4 GB of DDR4 memory and 32 GB of flash storage, the system handles demanding multimedia content and applications directly on the display, streamlining the entire AV setup.
Technical Overview
This collaboration display is built on a robust hardware platform centered on the Rockchip RK3399 system-on-chip. The processor manages the 4K video pipeline, the Android OS, and the extensive I/O simultaneously. The display itself is an LCD panel illuminated by a direct-view LED backlight array, achieving a high 600 cd/m² brightness level suitable for retail, corporate lobbies, and command centers.
Connectivity is comprehensive, featuring wired Gigabit Ethernet, dual-band Wi-Fi, and Bluetooth for network and peripheral attachment. The rear I/O panel includes seven USB ports for connecting storage drives, peripherals, or touch overlays, plus HDMI for external video sources, a serial port for control systems, and audio line-out. The integrated 60-watt stereo speaker system provides ample audio for medium to large rooms without external amplifiers.
Visual Performance
The 4K UHD resolution on a 231-inch canvas offers exceptional detail for presentations, video conferencing, and digital content. The 170-degree horizontal and vertical viewing angles maintain color and contrast for audiences viewing from the sides.

Localization and Operating System
The display ships with Android 9.0 Pie as its core operating system. This provides access to the Google Play Store for installing a vast ecosystem of business, utility, and signage-specific applications. The OS handles the device's networking, storage, and application runtime, offering a flexible platform for custom software development or off-the-shelf app deployment.
As an Android-based device, it supports standard touch and pointer input methods if a compatible touch overlay is added via USB. The system is configured for standard North American power input (120V AC) and includes RoHS environmental compliance.
