55” 4000 nits Fanless High Brightness Digital Signage Display Features: Product Highlights - Sunlight readable 4000 nits brightness, fanless cooling, Android™ based media player, LED backlight, blackening defect-free in direct sunlight, narrow 10.9 mm bezel, 1080p Full HD resolution. Android™ - An integrated Android™ based media player with WiFi offers users the freedom to select from the array of various media software solutions on the market or use the bundled DynaScan DSM365 application for local video playback, playlist creation, and content scheduling. Fanless Thermal Management - Eliminating life-shortening fans, the heat generated by the display is radiated away from high-temperature areas while a sensor continuously monitors the internal temperature to protect the system from overheating utilizing an advanced fanless thermal management system. TrueColor™ Calibration - Each screen is individually color calibrated to the D65 (6500K) CIE color standard. Not only does this produce a true, natural white, but also accurately reproduces brand colors, skin tones, and colorways. Blackening Defect Free - Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats. The DS552LT5-1 is equipped with a high-temperature LCD panel capable of withstanding temperatures up to 110˚C (230°F) without blackening – crucial for direct sunlight applications. Auto Brightness Control - Different external lighting conditions require different brightness levels. An onboard light sensor measures the ambient light in the area and automatically adjusts the image accordingly.
