The DS551LT7 is a 55 inch ultra high brightness professional LCD with IPS technology. With a brightness rating of 7,000 cd/m² this display features an LED back light for incredible, high contrast picture quality and low power consumption. The DS551LT7 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.
Key Features:
- Sunlight readable 7,000 cd/m² brightness
- LED backlit with local dimming
- Narrow 9.9 mm bezel for video wall applications
- 1,000,000:1 dynamic contrast ratio (3000:1 static)
- 1080p HD resolution
- Blackening defect free in direct sunlight
- Thermal management system
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.
Colour Temperature and Quality
The DS551LT7 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 DS551LT7 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.
Full HD Resolution
With a resolution of 1920 x 1080 Full HD, the DS551LT7 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.
Blackening Defect Free LCD Panel
Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats. The DS551LT7 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.
