Delivered by a full-array direct-lit LED matrix — not edge-lit. Uniform luminance across the entire 49-inch panel, with an integrated ambient light sensor that adjusts output in real time. Readable at a glance under fluorescent overhead lighting, next to uncovered windows, and in semi-outdoor concourse environments.
BRIGHTNESS COMPARISON
† Nominal brightness ratings. Actual ambient contrast depends on installation environment and surface treatment.
Decisions made for integrators,
not for the spec sheet.
Every hardware choice on this panel reflects the realities of commercial deployment: sustained brightness, thermal stability, flexible connectivity, and a form factor that installs cleanly into custom enclosures.
Sunlight Readable
2,500 cd/m² with auto lux-sensor dimming. Consistent luminance across the full panel without hot-spot artifacts from a direct-lit array.
Open-Frame Chassis
Sheet-metal body with front and rear standard screw patterns. Designed to mount cleanly inside kiosk enclosures, display cabinets, and custom rack assemblies.
RK3568 · Android 11
Quad-core Cortex-A55 at 1.8 GHz with 2 GB DDR3 and 16 GB eMMC. Full Android 11 with enterprise management APIs — no external media player needed.
Full Connectivity Stack
WiFi, Bluetooth, RJ45 Ethernet, HDMI 2.0 (4K input), 6× USB, SD card, plus optional 4G LTE for air-gapped or offline-resilient installs.
Enterprise Security
Hardware dongle authentication, tiered user permission management, login and control passwords. Meets common requirements in financial and government procurement.
−10 °C to +50 °C
Tested across the full operating envelope. Suitable for temperature-variable retail environments, warehouse edges, and installations near heat sources or ventilated enclosures.

Where the WD490D-M2 is specified.
Transit & Transportation
Airport concourses, metro platforms, and intercity rail hubs. The 89° wide viewing angle and 2,500-nit output serve both near and far passenger sight lines under mixed natural and artificial lighting.
Retail & QSR
High-ceiling stores and quick-service menu boards. The wide temperature range accommodates heat from kitchen proximity or ventilated display enclosures common in food-service environments.
Gaming & Hospitality
Casino floors with high ambient lighting and mandatory 24/7 uptime. The 50,000-hour backlight life directly reduces TCO relative to panels requiring periodic replacement cycles.
Industrial & Control Rooms
Factory-floor operator panels and process control rooms. Metal chassis and isolated power architecture suit industrial EMC environments where consumer-grade panels fail prematurely.
Financial & Government
Branch banking lobbies and government service counters. Multi-level security architecture, including hardware dongle support and tiered user permissions, addresses enterprise IT requirements.
Healthcare
Hospital corridors and clinic reception for patient flow and health communications. 24/7 operation rating and RoHS compliance align with typical healthcare facility procurement standards.
Every port and protocol.
