3 Ultra-High Brightness LED Backlight Built-in Video Wall Support DynaScan s DS² line of LCDs utilize a proprietary system of LED backlighting which is not only more energy efficient than traditional CCFL backlights, it is also considerably brighter. DynaScan has applied its LED expertise to create a collection of ultra-high brightness LCDs with maximum brightness ratings up to 5,000 cd/m². which can easily be viewed in direct sunlight such as storefront windows or outdoor enclosures. With built-in video daisy chaining, a single 1080p source can be used on video walls up to 6x6 in size without the need for any additional video wall controller. Local Dimming The display features a local dimming LED back light technique for a remarkably high contrast picture as high as 1,000,000:1 (dynamic). With direct local dimming, darker areas of an image receive less backlighting than lighter areas, as opposed to CCFL and edge-lit LED backlights which illuminate an entire screen at all times causing blacks and dark areas to appear washed out. Blackening Defect Free DynaScan offers most high brightness screens with IPS LCD panels which can withstand temperatures up to 110 C (230 F) without blackening - crucial for direct sunlight applications. Superior Color Quality DynaScan High Bright Professional LCDs come factory calibrated to D65 (6500 K) CIE color standard a feature lacking from many of the large format commercial LCDs currently on the market. As many displays have a tendency to be rather cool or bluish, these color settings produce a very natural looking image which has a correlated color temperature to that of daylight. Full HD 1080p With a resolution of 1920 x 1080 Full HD, DynaScan Professional LCDs provide a super sharp image for easy-to-read text and incredible detail. Fanless Thermal Management System 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. All of this is done without the use of any fans, resulting in silent operation and greatly reducing the potential of mechanical failure. This feature is especially beneficial in areas with a lot of dust which can eventually obstruct a vent and cause the display to overheat. Super Narrow Bezel Models DynaScan high brightness LCDs are available with bezel-tobezel widths as narrow as 5.3 mm, perfect for video wall and low profile enclosures. Automatic 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. Variety of Sizes and Styles One size does not fit all applications. DynaScan offer a full range of high brightness LCDs ranging from 46 to 72 in standard and narrow bezel styles. 24/7 Operation Designed for worry-free round the clock operation.
