The Dynascan DS471LT4 is a 47 inch professional high brightness LCD with IPS technology.

With a brightness rating of 1500 cd/m² this display features a local dimming LED back light technique for incredible, high contrast picture quality and low power consumption. The DS471LT3 features a 11 mm bezel width, perfect for video wall applications in bright environments.

High Brightness LED Backlit With Local Dimming
The DS471LT4 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 2,500-nit high brightness LCD 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, the DS471LT4 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 DS471LT4 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.
Narrow Bezel for Video Wall Applications
The DS471LT4 features a 11 mm narrow bezel display – perfect for video wall applications.  With built-in video daisy chaining, a single 1080p source can be used on video walls up to 6×6 in size without the need for any additional external video wall controller. By combining a narrow bezel display with the benefits of a high brightness LED back light, these displays are ideal for indoor environments that receive a high amount of external daylight such as airports, shopping centers and storefront window displays.
Blackening Defect Free
Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats.  The DS471LT4 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.

Full HD Resolution
With a resolution of 1920 x 1080 Full HD, the DS471LT4 provides a super sharp image for easy to read text and incredible detail.
