The DS381LT4 is a 38 inch ultra high brightness 3:1 ratio super wide aspect professional LCD with IPS technology. With a brightness rating of 2,500 cd/m² this display features an LED back light for incredible, high contrast picture quality and low power consumption. Designed for use in direct sunlight, the specially designed LCD panel prevents “blackening defect” caused by high temperatures.

Key Features:

    • Sunlight readable 2,500 cd/m² brightness
    • LED backlit with local dimming
    • 1,000,000:1 dynamic contrast ratio
    • 3:1 ratio screen layout (1920 x 538 native 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 DS381LT4 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.

Blackening Defect Free LCD Panel

Most residential and commercial screens will blacken or result in isotropic failure when the LCD panel overheats.  The DS381LT4 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 on-board light sensor measures the ambient light in the area and automatically adjusts the image accordingly.
