LED Backlit with Local Dimming
LED backlighting 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. The DS421LT4 utilizes a direct LED backlighting system 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 backlight technique for a remarkably high contrast picture. 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.
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 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.
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.
- 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. This is accomplished with ultra-quiet fans.
Full HD Resolution
With a resolution of 1920 x 1080 Full HD, the DS421LT4 provides a super sharp image for easy to read text and incredible detail.
The DS421LT4 is a 42-inch professional ultra-high brightness LCD. With a maximum brightness rating of 2,500 nits, this display features a local dimming LED back light for incredible, high contrast picture quality and low power consumption. The DS421LT4 features an intelligent thermal management system for ultra-quiet 24/7 operation.
