DS46LO4 Fanless 46" High Brightness LED Backlit Full HD LCD Digital Signage
Available from Dynascan Technology Inc
The DS46LO4 is a 46 inch ultra high brightness digital signage LCD featuring 1080p HD resolution. With a maximum brightness rating of 3,000 cd/m² this display produces a sunlight readable image which may easily be seen in storefront windows and other brightly lit indoor environments. The DS46LO4 features a fanless, proprietary thermal management system and a unique local dimming LED backlit technique for incredible, high contrast picture quality. The DS46LO4 utilizes 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 which can easilly be viewed in direct sunlight such as storefront windows or outdoor enclosures. 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.
