DynaScan DS46LO4, 3000 cd/m²

High Brightness LED Backlit with Local Dimming
LED back lighting is both more energy efficient and provides a much brighter image than traditional CCFL backlights. Due to the compact nature of LEDs, displays are also typically thinner. 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 easily 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.

Fanless Thermal Management System
Heat dissipation is always a concern when dealing with LCD panels operating around the clock. To increase performance and prolong the lifespan of the display, DynaScan’s DS² High Brightness Series utilizes a proprietary 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 is especially beneficial in areas with a lot of dust which can eventually obstruct a vent and cause the display to overheat.

Color Temperature and Quality
The DS46LO4 comes equipped to display both D55 (5500 K) and D65 (6500 K) CIE color standards right out of the box – 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.
