The GHI DS550 is a 55-inch floor-standing digital signage display that puts advertising at eye level in lobbies, malls, showrooms, and exhibition halls. The Full HD panel at 1920 by 1080 shows product photography, video, and wayfinding content across a display area of 1209.6 by 680.4 millimeters, large enough to catch attention from across a room. Brightness of 500 nits keeps the picture vivid under bright indoor lighting, and the 178-degree viewing angle means the content reads clearly from the side as well as straight ahead.
The panel is built for commercial display. The a-Si TFT-LCD panel with a matte surface and 1 percent haze resists fingerprints and reflections, and the 3H hard coating protects the screen during daily cleaning. The 1000 to 1 contrast ratio, 16.7 million colors, and 72 percent CIE1931 color coverage keep brand colors accurate, and the response time of 7 milliseconds rising and 5 milliseconds falling keeps video smooth. The WLED backlight is rated for 50,000 hours of operation, which covers years of daily use in a public space.
The DS550 is a complete advertising player, not just a screen. An A83T octa-core processor running at 2.0 gigahertz, with 1 or 2 gigabytes of memory and 8 gigabytes of eMMC storage, decodes video up to 1080p and runs content from its own storage without a separate player box. Three USB host ports, three USB sockets, and three serial ports connect storage, sensors, and peripherals, and two CVBS inputs accept analog video. Ethernet at 10 or 100 megabits keeps the unit on the venue network, and GPS, WiFi, and Bluetooth are available as options for remote updates and location-aware content.
Touch is available as an option. An infrared touch overlay with a tempered glass front in 3, 4, or 6 millimeter thickness turns the display into an interactive screen for directories, catalogs, and self-service information. The overlay transmits at least 95 percent of the light, responds in as little as 6 milliseconds, and is designed for more than five years of service. The screen works in stand-alone mode or with Android or Windows systems, and a timed switch turns the display on and off on schedule.
The DS550 is part of a floor-stand family in 43, 50, and 55 inches, so a venue can use the same design at different sizes across different spaces. The housing is only 3 centimeters thick, or 2 centimeters in the slim version, and comes in black, gold, or silver to match the interior. It operates from 0 to 50 degrees Celsius and stores from minus 20 to 60 degrees, which covers heated lobbies, air-conditioned malls, and covered walkways.
