DynaScan introduces a revolutionary leap for in-window display technology. The DS551DR4 is a dual-sided professional ultra-high brightness LCD. This all-in-one solution features back-to-back display surfaces in a single, ultra-slim form factor. With a sunlight viewable 3000 nit side and a 1000 nit brightness side on the reverse, the DS551DR4 is an ideal fit for in-window display applications. Every display is factory color calibrated for remarkable color reproduction, high contrast and superb picture quality. An included 1 meter base stand provides a custom tailored contemporary mounting solution. The DS551DR4 includes two integrated Android™-based media players for simultaneous playback of independent or duplicate video content and dual HDMI inputs.

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. 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.

Blackening Defect Free

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.

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 DS551DR4 provides a super sharp image for easy to read text and incredible detail.
