The DS551LT4 is a 55 inch ultra high brightness professional LCD with IPS technology. With a brightness rating of 3,000 cd/m² this display features an LED back light for incredible, high contrast picture quality and low power consumption. The DS551LT4 features a 19.8 mm bezel-to-bezel width, perfect for video wall applications in bright environments. Designed for use in direct sunlight, the specially designed LCD panel prevents “blackening defect” caused by high temperatures.
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 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.
Narrow Bezel for Video Walls
The DS551LT4 features a 9.9 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.
Color Temperature and Quality
Ensuring the color and brightness of each screen in a tiled matrix matches can be time consuming and requires additional calibration hardware. Each DynaScan DS551LT4 screen is individually color calibrated to the D65 (6500K) CIE color standard. Not only does this produce a true, natural white, the color of all screens will be uniform.
Blackening Defect Free
Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats. The DS551LT4 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 DS551LT4 provides a super sharp image for easy to read text and incredible detail
