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 utilise 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. 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

Ensuring the colour and brightness of each screen in a tiled matrix matches can be time consuming and requires additional calibration hardware. Each screen is individually colour calibrated to the D65 (6500K) CIE colour standard. Not only does this produce a true, natural white, the colour of all screens will be uniform.

Full HD Resolution
With a resolution of 1920 x 1080 Full HD, the DS551DR4 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 onboard 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 DS551DR4 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.
