The DS841LR4 is the largest professional LCD offering from DynaScan, measuring 84-inches diagonally. The display features a 4k Ultra-HD* 84-inch IPS LCD with a high brightness LED backlight producing a 2,500 nit sunlight viewable image. The DS841LR4 is designed for large scale display applications in high ambient light environments.
- World brightest 84 inch LCD: 2500 nits
- Equivalent to four 42-inch screens as a video wall without bezel lines.
- 84-inch display area, 1860.48(H) mm x 1046.52(V) mm, about 6-sheet European poster size.
- No blackening defect panel capable of withstand high temperatures
- Wide viewing angle with IPS panel technology
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 LCD’s 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 DS841LT4 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 LCD’s currently on the market. As many displays have a tendency to be rather cool or blueish, these colour settings produce a very natural looking image which has a correlated colour temperature to that of daylight.
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.
*Although the LCD panel has a native UHD resolution the monitor only accepts standard Full HD input signals which are scaled to fit the screen. Support for true UHD signals will be introduced once HDMI 2.0 is implemented fully.[wpex more=”Full Specifications: (click to expand)” less=”Close Specifications: (click to close)”]
