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. 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 which can easily be viewed in direct sunlight such as store front 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.
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.
Colour Temperature and Quality
The DS47LT4 comes equipped to display both D55 (5500 K) and D65 (6500 K) CIE colour 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 colour settings produce a very natural looking image which has a correlated colour temperature to that of daylight.
Narrow Bezel for Video Wall Applications
The DS47LT4 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 centres and store front window displays
Full HD Resolution
With a resolution of 1920 x 1080 Full HD, the DS47LT4 provides a super sharp image for easy to read text and incredible detail
Auto Brightness Control
Different external lighting conditions require different brightness levels. An on-board light sensor measures the ambient light in the area and automatically adjusts the image accordingly.
